EXCEL 10 W7761A INPUT/OUTPUT DEVICE  
Control Application  
The W7761A, Excel 10 Remote Input/Output device, provides auxiliary inputs and outputs for use with an Excel 10 Zone  
®
®
Manager and Excel 10 controllers over the Echelon LonWorks E-Bus. The W7761A Remote Input/Output Device can be  
connected to outdoor air temperature and humidity sensors that can be used by other Excel 10 controllers on the E-Bus or  
Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. This would allow the controllers to use their physical  
inputs for monitoring other elements such as return humidity, IAQ, etc. to achieve better control. The W7761A can be used to  
average many space temperature sensors that are located in a zone that is controlled by the W7750 Constant Volume AHU  
Controller. The W7761A device has 8 Digital Outputs which may be Discrete, Modulating or Floating. For example, this allows  
the control of lighting zones, miscellaneous exhaust or ventilation fans, miscellaneous pumps, and can enable freeze  
protection. See Fig. 2.

Control Provided  
The W7761A was not intended to control staged or modulating heating/cooling coils, mixed air economizer dampers, or system  
fan/heat pump units. The W7761A contains inputs and outputs, but no control software. All control that would be associated  
with the inputs and outputs in the W7761A would be accomplished though the Excel Zone Manager and would not be suitable  
for VAV control, temperature control, or any control function that would require less than a 30 second update rate.

attached to the screw terminal blocks on both sides of the device. Connection for operator access to the E-Bus is provided by  
plugging the SLTA connector cable into the communications jack.  
A channel in the cover allows the device status LED to be visible when the cover is in place. There are no field-serviceable  
parts on the circuit board and, therefore, it is intended that the cover never be removed.  
The W7761A can be mounted in any orientation. Ventilation openings were designed into the cover to allow proper heat  
dissipation regardless of the mounting orientation. See Fig. 3 and 4.

Power:  
24 Vac with a minimum of 20 Vac and a maximum of 30 Vac at either 50 or 60 Hz. The W7761A power consumption is 6 VA  
maximum at 50 or 60 Hz. The W7761A is a NEC Class 2 rated device. This listing imposes limits on the amount of power the  
product can consume or directly control to a total of 100 VA (U.S. only).  
The individual Triac outputs incorporate an internal common connection with the input power transformer. The Triacs provide a  
switched path from the hot side (R) of the transformer through the load to the common of the transformer. The W7761A Device  
design must use the same power transformer for any loads connected to that device; see Fig. 19.  
Each individual Triac is rated 500mA at 30 Vac maximum. Under all operating conditions, the maximum load/source power  
budget for the W7761A Device is 100 VA.

CPU:  
Motorola or Toshiba 3150 Neuron processor, containing three eight-bit CPU’s. Each Neuron has a unique 48-bit network  
identification number.  
Memory Capacity:  
64K ROM/PROM (6K reserved for network operations, 58K usable for control algorithm code).  
512 bytes EEPROM.  
2K RAM.  
Specified Space Temperature Sensing Range:  
45 to 99°F (7 to 37°C) with an allowable control setpoint range from 50 to 90°F (10 to 32°C) when initiated from the network  
and 55 to 85°F (13 to 29°C) when configured and connected to T7770 Wall Modules or T7780 DDWM.  
Communications:  
The W7761A Device uses a transformer-coupled communications port with differential Manchester-encoded data at 78 kilobits  
per second (kbs). The transformer-coupled communications interface offers a much higher degree of common-mode noise  
rejection while ensuring dc isolation.  
Approved cable types for E-Bus communications wiring is Level IV 22 AWG (0.34 mm2) plenum or non-plenum rated  
2
unshielded, twisted pair, solid conductor wire. For non-plenum areas, use Level IV 22 AWG (0.34 mm ) such as U.S. part  
2
AK3781 (one pair) or U.S. part AK3782 (two pair). In plenum areas, use plenum-rated Level IV, 22 AWG (0.34 mm ) such as  
U.S. part AK3791 (one pair) or U.S. part AK3792 (two pair). (See Tables 6 and 8 for part numbers.) Contact Echelon Corp.  
Technical Support for the recommended vendors of Echelon approved cables.  
The Free Topology Transceiver (FTT) supports polarity insensitive free topology wiring. This frees the system installer from the  
need to wire using a bus topology. Star, bus, mixed, and loop wiring are all supported by this architecture. The maximum E-Bus  
length when using a combination of star, loop, and bus wiring (singly terminated) is 1640 ft (500m) with the maximum node-to-  
node length of 1312 ft (400m). In the event that the total wire length is exceeded, then a Q7740A 2-Way Repeater or a Q7740B  
4-Way Repeater can be used to allow the number of devices to be spread out as well as increasing the length of wire over  
which they communicate. The maximum number of repeaters per segment is one (on either side of the router). A Q7751A E-  
Bus Router can also be used to effectively double the maximum E-Bus length. The advantage of using the router is that it will  
segregate traffic to a segment while when using the repeater, all traffic is repeated on each segment. When utilizing a doubly  
terminated E-Bus structure, use a continuous daisy-chain with no stubs or taps from the main backbone, The maximum E-Bus  
length is 4593 ft (1400m) with the maximum node-to-node length of 3773 ft (1150m).  
FTT networks are very flexible and convenient to install and maintain, but it is imperative to carefully plan the network layout  
and create and maintain accurate documentation. Unknown or inaccurate wire run lengths, node-to-node distances, node  
counts, total wire length, and misplaced or missing terminators can cause poor network performance. Refer to E-Bus Wiring  
Guidelines form, 74-2865 for complete description of network topology rules.

Configurations  
Each W7761A device can control or monitor a variety of different types of mechanical equipment. The W7761A was not  
intended to control staged or modulating heating/cooling coils, mixed air economizer dampers, or system fan/heat pump units.  
The W7761A contains inputs and outputs, but no control software. All control that would be associated with the inputs and  
outputs in the W7761A would be accomplished though the Excel Zone Manager and would not be suitable for VAV control,  
temperature control, or any control function that would require less than a 30 second update rate.  
It would be suitable to control miscellaneous exhaust or ventilation fans, lighting zones that are spread out through a building  
which need to be linked to a start/stop time program through the Zone Manager or to enable freeze protection. The W7761A  
device can be connected to outdoor air temperature and humidity sensors that can be used by other Excel 10 controllers on  
the E-Bus or Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. The W7761A can be used to monitor  
Occupancy, Window, Dirty filter, Indoor air quality, and Smoke control sensors. This allows the controllers to use their physical  
inputs for monitoring other elements such as return humidity, IAQ, etc. to achieve better control. The W7761A can be used to

EXCEL 10 W7761A INPUT/OUTPUT DEVICE  
average many space temperature sensors that are located in a zone that is controlled by the W7750 Constant Volume AHU  
Controller.  
Mixed-Output-Type Control  
The W7761A Device can control mixed-output-types of applications such as PWM and staged control occurring simultaneously  
with Series 60 Floating Control.  
Occupancy Sensor  
Excel 10 W7761A device can be connected to an occupancy sensor through a digital input. This is a device, such as a passive  
infrared motion detector, that contains a dry contact (see following NOTE) closure to indicate whether or not people are present  
in the space. The Excel 10 W7761A Device expects a contact closure to indicate the space is Occupied. See Fig. 18 in  
Application Step 4, Prepare Wiring Diagrams, for details on wiring connections. This occupancy sensor can then be bound to  
other Excel 10 controllers on the E-Bus or Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. This  
would allow the other Excel 10 controllers to use their physical inputs for monitoring other elements such as return humidity,  
IAQ, etc. to achieve better control.  
NOTE: The Excel 10 Controllers (W7750 CVAHU and W7761A RIO) have limited power available (only 9 mA at 4.8 volts) for  
checking the digital inputs for contact closures. It is very important that the device used contains high quality,  
noncorroding contacts with resistivity that does not degrade; that is, increase over time. Use noble metal (such as  
gold or silver), pimpled or sealed contacts to assure consistent, long-term operation.  
The recommended devices for use with the Excel 10 W7750 Controller and W7761A Device are the EL7628A1007 Ceiling  
Mounted Infrared or the EL7680A1008 Wall Mounted Wide View Infrared Occupancy Sensors. If ultrasonic sensors are  
required, the EL7611A1003 and the EL7612A1001 Occupancy Sensors are recommended. An EL76XX Power Supply/Control  
Unit is required for use with these occupancy sensors. The EL7630A1003 can power up to four sensors, and is multi-tapped for  
several line voltages. The EL7621A1002 can power three sensors and it connects to 120 Vac line voltage. The EL7621A1010  
can also power three sensors but it connects to 277 Vac line voltage.  
Window Open/Closed Digital Input  
Excel 10 W7761A device can be connected to a window sensor to indicate whether a window in the space was opened. The  
Excel 10 W7761A device can be connected to a dry contact (see the NOTE for the Occupancy Sensor and Fig. 18 in  
Application Step 4. Prepare Wiring Diagrams, for details) or a set of contacts wired in series (for monitoring multiple windows)  
to verify that the window(s) are closed. This window(s) sensor can then be bound to other Excel 10 controllers on the E-Bus or  
Excel 5000 controllers on the C-Bus through the Excel 10 Zone Manager. The algorithm in the other Excel 10 controllers  
expects a contact closure to indicate the window is closed. If an open window is detected, the algorithm in the other Excel 10  
controllers changes the mode of operation to FREEZE_PROTECT, which shuts down the control functions, and watches for  
low space temperature conditions. The freeze protection setpoint is 46.4°F (8°C), and the frost alarm occurs at 42.8°F (6°C).  
Wall Module Options  
As previously discussed, there are five basic varieties of the T7770. There is one variety of the PT3000 sensor and the T7780  
DDWM (see the Product Names and the Construction sections). The T7770A,B,C,D 20Kohm NTC sensor—(current feature  
that can be used with the RIO Device) and one PT3000 sensor can be configured on any of the four resistive inputs. The  
T7780 is an E-Bus node and would not be directly connected to the RIO Device.  
Dirty Filter Monitor  
The air filter in the air handler can be monitored by the W7761A RIO device and an alarm issued by the Zone Manager when  
the filter media needs replacement. The two methods of monitoring the filter are:  
1. Connecting a differential pressure switch to a digital input on the W7761A.  
2. Wiring a 2-to-10V differential pressure sensor to a voltage input on the W7761A. If the analog input sensor is used, its  
measured value 0 to 5 inw (0 to 1.25 kPa) is compared to a user-selectable setpoint. The comparison is done in the  
Zone Manager —valid range: 0 to 5 inw (0 to 1.25 kPa), and the Dirty Filter alarm is issued when the pressure drop  
across the filter exceeds the setpoint.  
Indoor Air Quality (IAQ)  
The Excel 10 W7761A device can monitor IAQ using one of two different methods of detecting poor air quality. The first is with  
an IAQ switch device connected to a digital input on the W7761A, where a contact closure indicates poor air quality, and an  
alarm can be issued by the Zone Manager. The device can detect poor air quality using any desired measure such as CO2,  
VOC, CO, etc. The second method, is through an analog input that connects to a CO2 sensor (0 to 10V). The measured value  
of CO2 from this sensor (0 to 2000 ppm) is compared to a user-selectable setpoint (the comparison is done in the Zone  
Manager —valid range: 0 to 2000 ppm), and an IAQ alarm can be issued when the CO2 level exceeds the setpoint. The IAQ  
sensor that is connected to the W7750 RIO, can be bound to other W7750 CVAHU Excel 10 controllers on the E-Bus.

APPLICATION STEPS  
Overview  
The seven application steps shown in Table 3 are planning considerations for engineering an Excel 10 W7761 Remote  
Input/Output Device. These steps are guidelines intended to aid understanding of the product I/O options, bus arrangement  
choices and the Excel 10 W7761A Devices role in the overall EXCEL 5000® System architecture.

Troubleshooting  
Step 1. Plan The System  
Plan the use of the W7761A Devices according to the job requirements. Determine the location, functionality and sensor or  
actuator usage. Verify the sales estimate of the number of W7761A Devices and the number and type of output actuators and  
other required accessories.  
When planning the system layout, consider potential expansion possibilities to allow for future growth. Planning is very  
important to be prepared for adding HVAC systems and controllers in future projects.  
T7770A,B,C,D Wall Modules (sensor—current feature that can be used with the RIO Device)can be installed as either  
hardwired I/O-only devices or additional wiring can be run to them (for the E-Bus network ) to allow a CARE/E-Vision operator  
terminal to have access to the E-Bus. The application engineer needs to determine how many wall modules or other input  
sensors are required. This information is required during installation to ensure that the proper number and type of wires are  
pulled to the wall modules, and the building operators are informed about where they can plug in to the E-Bus network with a  
portable operator terminal (see Fig. 8 through 10).  
Fig. 8. Connecting the portable operator terminal to the E-Bus.  
The FTT communication loop, (E-Bus) between controllers is a free topology wiring scheme that supports star, loop, and/or bus  
wiring. Refer to the E-Bus Wiring Guidelines form, 74-2865 for complete description of network topology rules. See Application  
Step 3. Lay Out Communications and Power Wiring, for more information on bus wiring layout, and see Fig. 16 through 19 in  
Application Step 4. Prepare Wiring Diagrams, for wiring details.  
The application engineer must review the Direct Digital Control (DDC) job requirements. This includes the Sequences of  
Operation for the Excel 10 controllers, and for the system as a whole. Usually there are variables that must be passed between  
the W7750 (CVAHU), Q7750A Zone Manager, W7761 (RIO), and other Excel 10 controller(s), or central plant controller(s) that  
are required for optimum system-wide operation. Typical examples are the TOD Occ/Unocc signal, the outdoor air  
temperature, demand limit control signal, and smoke control mode signal.

It is important to understand these interrelationships early in the job engineering process to ensure implementing when  
configuring the controllers. (See Application Step 6. Configure Devices, for information on the various Excel 10 parameters and  
on Excel 10 point mapping.)  
Step 2. Determine Other Bus Devices Required  
A maximum of 62 nodes can communicate on a single E-Bus segment. Each W7761A (RIO), W7750 (CVAHU), W7751 (VAV)  
Controller or T7780 Wall Module constitutes one node. If more nodes are required, a Q7751A Router is necessary. Using a  
router allows up to 125 nodes, divided between two E-Bus segments. The router accounts for two of these nodes (one node on  
each side of the router); a Q7750A Excel 10 Zone Manager takes one node and two nodes are available for operator terminal  
nodes, leaving 120 nodes available for Excel 10 Controllers and T7780 Wall Modules. All 120 controllers and T7780 Wall  
Modules are able to talk to each other through the router. A Q7750A Excel 10 Zone Manager is required to connect the E-Bus  
to the standard EXCEL 5000® System C-Bus. Each Excel 10 Zone Manager can support no more than 120 Excel 10  
Controllers and T7780 Wall Modules. This limit is set in the Excel 10 Zone Manager database as an absolute maximum.  
Each E-Bus segment is set up with two unused nodes to allow for a CARE/E-Vision or Hand Held Tool (HHT) to be connected  
to the E-Bus. Multiple CARE/E-Vision or HHT terminals can be connected to the bus at the same time. Table 4 summarizes the  
E-Bus segment configuration rules.

Refer to the E-Bus Wiring Guidelines form, 74-2865 for complete description of network topology rules and the maximum wire  
length limitations. If longer runs are required, a Q7740A 2-way or Q7740B 4-way repeater can be added to extend the length of  
the E-Bus. A Q7751A Router can be added to partition the system into two segments and effectively double the length of the  
E-Bus. Only one router is allowed with each Excel 10 Zone Manager and each network segment can have a maximum of 1  
repeater. In addition, all E-Bus segments require the installation of a Bus Termination Module for a singly terminated E-Bus or  
two Bus Termination Modules for a doubly terminated E-Bus. For more details on E-Bus termination, refer to the E-Bus Wiring  
Guidelines form, 74-2865, or see Application Step 3. Lay Out Communications and Power Wiring, and the E-Bus Termination  
Module subsection in Application Step 4.

Unswitched 24 Vac power wiring can be run in the same conduit as the E-Bus cable.  
Do not use different wire types or gauges on the same E-Bus segment. The step change in line impedance  
characteristics causes unpredictable reflections on the bus. When using different types is unavoidable, use a  
Q7751A Router at the junction.  
•

•
•
In noisy (high EMI) environments, avoid wire runs parallel to noisy power cables, or lines containing lighting  
dimmer switches, and keep at least 3 in. (76 mm) of separation between noisy lines and the E-Bus cable.  
Make sure that neither of the E-Bus wires is grounded.  
Power Wiring  
A power budget must be calculated for each Excel 10 W7761 Device to determine the required transformer size for proper  
operation. A power budget is simply the summing of the maximum power draw ratings (in VA) of all the devices to be controlled  
by an Excel 10 W7761 Device. This includes the device itself, the equipment actuators (ML6161, or other motors) and various  
contactors and transducers, as appropriate, for the Excel 10 configuration.

The Excel 10 System example requires 29.9 VA of peak power; therefore, a 40 VA AT72D Transformer is able to provide  
ample power for this device and its accessories. Alternatively, a 75 VA AT88A Transformer could be used to power two Excel  
10 Systems of this type, or a 100 VA AT92A Transformer could be used to power three of these controllers and meet NEC  
Class 2 restrictions (no greater than 100 VA). See Fig. 12 through 14 for illustrations of power wiring details. See Table 5 for  
VA ratings of various devices.

For contactors and similar devices, the in-rush power ratings should be used as the worst case values when performing power  
budget calculations. Also, the application engineer must consider the possible combinations of simultaneously energized  
outputs and calculate the VA ratings accordingly. The worst case, that uses the largest possible VA load, should be determined  
when sizing the transformer.  
Line Loss  
Excel 10 Controllers must receive a minimum supply voltage of 20 Vac. If long power or output wire runs are required, a  
voltage drop due to Ohms Law (I x R) line loss must be considered. This line loss can result in a significant increase in total  
power required and thereby affect transformer sizing. The following example is an I x R line-loss calculation for a 200 ft (61m)  
run from the transformer to a W7761 Device drawing 37 VA using 18 AWG (1.0 mm2) wire.  
The formula is:  
Loss = [length of round-trip wire run (ft)] x [resistance in wire (ohms per ft)] x [current in wire (amperes)]  
From specification data:  
18 AWG twisted pair wire has 6.52 ohms per 1000 feet.  
Loss = [(200 ft) x (2 - round-trip) x (6.52/1000 ohms per ft)] x [(37 VA)/(24V)] = 4.02 volts  
This means that four volts are going to be lost between the transformer and the device; therefore, to assure the device receives  
at least 20 volts, the transformer must output more than 24 volts. Because all transformer output voltage levels depend on the  
size of the connected load, a larger transformer outputs a higher voltage than a smaller one for a given load. Fig. 11 shows this  
voltage load dependence.  
In the preceding I x R loss example, even though the device load is only 37 VA, a standard 40 VA transformer is not sufficient  
due to the line loss. From Fig. 11, a 40 VA transformer is just under 100 percent loaded (for the 37 VA device) and, therefore,  
has a secondary voltage of 22.9 volts. (Use the lower edge of the shaded zone in Fig. 11 that represents the worst case  
conditions.) When the I x R loss of four volts is subtracted, only 18.9 volts reaches the device, which is not enough voltage for  
proper operation.  
In this situation, the engineer basically has three alternatives:  
1. Use a larger transformer; for example, if an 80 VA model is used, see Fig. 11, an output of 24.4 volts minus the four volt  
line loss supplies 20.4V to the device. Although acceptable, the four-volt line-loss in this example is higher than  
recommended. See the following IMPORTANT.  
2. Use heavier gauge wire for the power run. 14 AWG (2.0 mm2) wire has a resistance of 2.57 ohms per 1000 ft which,  
using the preceding formula, gives a line-loss of only 1.58 volts (compared with 4.02 volts). This would allow a 40 VA  
transformer to be used. 14 AWG (2.0 mm2) wire is the recommended wire size for 24 Vac wiring.  
3. Locate the transformer closer to the device, thereby reducing the length of the wire run, and the line loss.  
The issue of line-loss is also important in the case of the output wiring connected to the Triac digital outputs. The same formula  
and method are used. The rule to remember is to keep all power and output wire runs as short as practical. When necessary,  
use heavier gauge wire, a bigger transformer, or install the transformer closer to the device.

EXCEL 10 W7761A INPUT/OUTPUT DEVICE  
No installation should be designed where the line loss is greater than two volts to allow for nominal operation if the  
primary voltage drops to 102 Vac (120 Vac minus 15 percent).  
To meet the National Electrical Manufacturers Association (NEMA) standards, a transformer must stay within the NEMA limits.  
The chart in Fig. 11 shows the required limits at various loads.  
With 100 percent load, the transformer secondary must supply between 23 and 25 volts to meet the NEMA standard. When a  
purchased transformer meets the NEMA standard DC20-1986, the transformer voltage-regulating ability can be considered  
reliable. Compliance with the NEMA standard is voluntary.

Notes on power wiring:  
•
•
•
All field wiring must conform to local codes and ordinances.  
To maintain NEC Class 2 and UL ratings, the installation must use transformers of 100 VA or less capacity.  
For multiple controllers operating from a single transformer, the same side of the transformer secondary must be  
connected to the same input terminal in each device and the ground terminals (1 on the W7761A) must be  
connected to a verified earth ground for each device in the group. See Fig. 13. (Device configurations are not  
necessarily limited to three devices per transformer.)  
•
•
•
•
For the W7761A Device (which has Triac outputs), all output devices must be powered from the same transformer  
as the one powering the Excel 10 W7761A Device.  
Use the heaviest gauge wire available, up to 14 AWG (2.0 mm2) with a minimum of 18 AWG (1.0 mm2) for all  
power and earth ground connections.  
To minimize EMI noise, do not run Triac output wires in the same conduit as the input wires or the E-Bus  
communications loop.  
Unswitched 24 Vac power wiring can be run in the same conduit as the E-Bus cable.

•
Make earth ground connections with the shortest possible wire run using 14 AWG (2.0 mm2) wire. A good earth  
ground is essential for W7761A operation. Ideally, connect the earth ground to the ground bus at a motor control  
center or circuit breaker panel. However, if the nearest ideal earth ground is inaccessible, consider an alternate  
source for earth ground. Metal water pipe is generally a good ground, but do not use sprinkler pipe if prohibited by  
local codes. Attention must be given when duct work, conduit, or rebar are to be considered as ground sources. It  
is the responsibility of the installer to assure that these structures are tied back to a known earth ground.  
Step 4. Prepare Wiring Diagrams  
General Considerations  
The purpose of this step is to assist the application engineer in developing job drawings to meet job specifications. Wiring  
details are included for the W7761A device the T7770A,B,C,D wall module (sensor—current feature that can be used with the  
RIO Device) and the T7780 DDWM. The drawings detail I/O, power, and communication bus wiring connections.  
NOTE: For field wiring, when two or more wires are to be attached to the same connector block terminal, be sure to twist  
them together. Deviation from this rule can result in improper electrical contact. See Fig. 15.  
The connector block terminals on the W7761A and on the T7770 accept 14 through 22 AWG (2.0 to 0.34 mm2) wire. Table 6  
lists wiring types, sizes, and length restrictions for Excel 10 products.

provided by plugging the connector into the communications jack.  
NOTE: If an Excel 10 W7761A Device or Zone Manager is not connected to a good earth ground, the device internal transient  
protection circuitry is compromised and the function of protecting the device from noise and power line spikes cannot  
be fulfilled. This can result in a damaged circuit board and require replacing the device.

Alarms  
When an Excel 10 has an alarm condition, it reports it to the central node on the E-Bus (typically, the Excel 10 Zone Manager).  
See Table 9. Information contained in an alarm message is:  
• Subnet Number:  
E-Bus subnet that contains the Excel 10 node that has the alarm condition. Subnet 1 is on the Zone Manager side of the  
router; Subnet 2 is on the other side.  
• Node Number:  
Excel 10 node that has the alarm condition (see Network Status).  
• Alarm Type:  
Specific alarm being issued. An Excel 10 can provide the alarm types listed in Table 9.

RETURN_TO_NORMAL  
128U  
Return to no alarm after being in an alarm condition. This code is added  
numerically to another alarm code to indicate that the alarm condition has  
returned to normal.  
ALARM_NOTIFY_DISABLED 255U  
The alarm reporting has been turned off by the DestManMode. No more  
alarms are reported via nvoAlarm until DestManMode turns on alarm repor  
or upon application restart.  
NO_ALARM  
0
1
No alarms presently detected.  
INPUT_NV_FAILURE  
One or more NV inputs have failed in receiving an update within their spec  
FAILURE_DETECT_TIME.  
NODE_DISABLED  
2
The control algorithm has stopped because the RIO device is in  
DISABLED_MODE, MANUAL, or FACTORY_TEST mode. No more alarms  
reported when the device is in the DISABLED_MODE. Alarms continue to  
reported if the device is in the MANUAL or FACTORY_TEST mode. The  
control is shut down and disabled until power is cycled or the node is reset  
See note 1 below.  
SENSOR_FAILURE  
3
One or more sensors have failed.  
NOTE: The node can be reset by switching the node to MANUAL and then to the normal operating mode.  
Also, the Excel 10 variables, AlarmLogX where X is 1 through 5, that store the last five alarms to occur in the device, are  
available. These points can be viewed through XBS or E-Vision.  
Broadcasting the Service Message  
The Service Message allows a device on the E-Bus to be positively identified. The Service Message contains the device ID  
number and, therefore, can be used to confirm the physical location of a particular Excel 10 in a building.  
There are two methods of broadcasting the Service Message from an Excel 10 W7761A Device. One uses a hardware service  
pin button on the side of the device (see Fig. 24). The other involves using the PC Configuration tool, as follows.  
The commissioning tool is used to perform the ID Assignment task (see the E-Vision User’s Guide form, 74-2588).

APPENDICES  
Appendix A. Using E-Vision to Commission a W7761 Device.  
CARE/E-Vision must be used to configure the W7761 device. The inputs and outputs will be configured through the application  
selection menu (see E-Vision user guide form, 74-2588). The RIO does not contain control loops for directly controlling the  
digital outputs, therefore the Zone Manager or some other device has to be bound to the outputs to perform the control  
function. Refer to the CARE User’s Manual form, 74-5587 to add Control Strategy, Switching Logic, or Time Programs for  
control of the RIO digital outputs. Refer to the E-Vision user guide (form, 74-2588 for the RIO commissioning procedure and  
updating/downloading of the Zone Manager files.  
NOTE: The RIO device does not synchronize the floating digital outputs. This function (position is synchronized whenever an  
endpoint is reached (full open or full close).and when the elapsed time since the last synchronization is 24 hours)  
must be done by the controlling device (such as the Zone Manager).  
SENSOR CALIBRATION  
The resistive temperature sensors and voltage/current inputs can all be calibrated. The wall module setpoint potentiometer is  
not supported on the W7761A. Perform the sensor calibration by adding an offset value (either positive or negative) to the  
sensed value using E-Vision menus (see E-Vision user guide form, 74-2588).  
When calibrating voltage/current sensors on the W7761A, the offset amount entered by the user is in volts, regardless of the  
inputs actual engineering units. See Appendix E for information on how to derive the proper voltage value to enter as an offset  
during calibration.  
CUSTOM MAPPING  
The RIO default CARE plant contains all available points that are supported on the RIO device. If the RIO plant was  
customized by deleting unused points, then the Custom mapping feature will have to be used to add points back into the plant  
so that they can be used or monitored by other devices. The following procedures will describe the Custom mapping process  
for adding analog/digital inputs and digital outputs.  
ADDING ANALOG INPUTS - ENTHALPY (4 to 20 mA)  
To add an enthalpy (outdoor or return air) sensor to an RIO plant, the user must add a software point (pseudo analog) that can  
be mapped to the actual hardware input through the Custom Mapping function of E-Vision. The following procedure will instruct  
the user on adding the pseudo analog and using the Custom Mapping function. This allows the enthalpy input to be used with  
other Excel 10 controllers (referenced) on the E-Bus, used in Zone Manager control strategy or switching logic, or be used with  
Excel 5000 controllers on the C-Bus.  
1. With CARE running, open an existing RIO plant. The user can go into either switching logic or control strategy to add the  
pseudo analog point. If the user does not have an existing control loop through control strategy, use switching logic to  
add the pseudo point, otherwise a control loop will have to be created along with unnecessary RACL to add the point.

This procedure will use switching logic to add the pseudo analog point. With the RIO plant having the focus, go into  
switching logic. Select the Software Points menu item and then Pseudo Analog. The Create/Select Software Point <Va>  
dialog box will be displayed. Type in a New point name for the enthalpy sensor (such as OaEnthaply) and click on the OK  
button. The new point that was just created will be added to the screen as the header point for switching logic table and  
also added to the Point List . Select the Cancel button to exit the Create/Select Software Point <Va> dialog box. Exit  
switching logic by selecting the File menu item and Exit. CARE will display the Delete Unused Software Points list box.  
Click the Cancel button to continue.  
2. Go into the Data Point Editor (Controller/Edit/Data Point Editor) and under Point select the pseudo analog point that was  
just created and click the OK button. Select the drop down list for the Engineering Unit and scroll through the list until the  
mA (mA matches the engineering unit of the RIO input) engineering units are displayed. Select the mA engineering unit  
that is shown with one decimal place (number 66) and click the OK button to save the selection. Cancel the User  
Address list box and select File/Exit to exit out of the Data Point Editor.  
3. Translate the Zone Manager and Export the Zone Manager files to E-Vision by selecting the Project and Export to E-  
Vision menu items. Type in the name of the Zone Manager Export file when the Export Zone Manager dialog box is  
displayed. Select the project and the Zone manager within that project that is being exported and click the Export button.  
Exit CARE and Start E-Vision. Select the E-Vision project to open and the CARE Export Filename created above. Once  
the project is open, select the RIO device that the enthalpy sensor is connected to and go into the Application Selection  
screen (offline) by selecting the Controller, then the Application Selection menu items. From the Inputs tab of the  
Application Selection dialog box, add Oa_Enthalpy to either analog input 5 or 6 and select the OK button to save the  
selection.  
4. Select the Controller menu item and then Import from CARE to import the Zone Manager files with the new pseudo  
analog point. If this function has already been performed before, the user will be prompted with the message CARE  
Export File has already been imported, do you want to import again?. Select Yes to continue with the Import. When the  
import is finished, E-Vision displays the message CARE Export File has been imported. Select OK to continue.  
5. Select the Network menu item and then Map C-Bus Points. Select RIO1 as the Controller Type from the Map C-Bus  
Points dialog box. Under Unmapped CARE, select the name of the RIO device that the enthalpy sensor was added to in  
CARE. Under Unmapped Excel 10, select the name of the RIO device that the actual enthalpy sensor was added to  
(both names should be the same). Next, select the Custom button and the Custom Mapping CARE Points dialog box will  
be displayed. Select the OaEnthalpy point under CARE Points and CurrentAI under Excel 10. CurrentAI is the user  
address in the RIO device that contains the actual sensor value for the OaEnthalpy (C7400A1004, 4 to 20 mA device).  
Select the Map button to add the OaEnthalpy point to the list of Mapped Points. Click on the Close button to exit the  
Custom Mapping CARE Points dialog box. Click on the Close button to exit the Map C-Bus Points dialog box.  
6. To use the OaEnthalpy custom mapped point with other Excel 10 controllers on the E-Bus, select the Network menu item  
and Refer Excel 10 Points. Select the RIO device name as the Source Excel 10 and then scroll down the list of Excel 10  
Points: until you reach CurrentAI and select it. Select an Excel 10 controller from the Destination Excel 10 list. For  
example if the user had selected a CVAHU controller from the Destination Excel 10 list, the user would select from the  
Excel 10 Points list as the destination point and then click on the Add button to add the point association (Binding)  
between the RIO and CVAHU controllers. If DestOaEnth is already being used in an association, then the message At  
Least one of the output network variables is in an existing connection and E-Vision will not allow this association to be  
added. In order to add this association, the user has to remove any other associations with the DestOaEnth point. Select  
the Close button to exit out of the Refer Excel 10 Points dialog box. Any controllers involved in the new association or  
change in an existing association will require commissioning.  
7. Select the Controller menu item and the Update Zone Manager Files. E-Vision will add the custom mapping information  
to the Zone Manager files. When the Update Zone Manager Files function is done, commission any controllers that need  
to be commissioned, then close the E-Vision project and exit out of E-Vision.  
8. Start CARE and open the Zone Manager that was just updated through the Update Zone Manager Files function and  
start XI584 by selecting the Controller, Tools and XI584 menu items. Once XI584 is started, select the Utilities and File  
Transfer menu items and select CARE Import. Select the project and the Zone Manager that was just updated and select  
Import and click OK on the Select Target Controller dialog box. When the CARE Import is complete, close the CARE  
Import dialog box. If this is the initial loading of the Zone Manager, then it will have to be reset and the CPU address set  
by the XI581 Emulation function (Applications, XI581 Emulation menu). Select the Utilities, File Transfer menu items and  
select Download. The Download dialog box will be displayed. Check the All selection and click the Controller button.  
When the Select Controller/Subsystem dialog box is displayed, make sure that the correct CPU address or name is high  
lighted and select the OK button. Click the Download button and click Yes to the message Replace updated application  
part in controller (CPU address or Controller name). When the download is complete, exit out of the Download dialog  
box. From the XI584 main menu, select the Data, Access by User Address menu items. Type OaEnthalpy in the Search  
For User Address and click the Search button. When the OaEnthalpy point displays in the User Addresses list, click on  
the point and select the Attributes button. XI584 will now display the value of the enthalpy sensor connected to the RIO  
device. This point can now be used in the Zone Manager control strategy or switching logic. This point can be used in  
other Excel 5000 (C-Bus) controllers by assigning a global analog point in the destination controller with the user address  
name of OaEnthalpy. Refer to the CARE User’s Manual form, 74-5587 for information on creating global points in Excel  
5000 controllers.  
ADDING OTHER VOLTAGE/CURRENT SENSORS  
See Table A-1 for the supported Voltage/Current analog input sensors that can be connected to the RIO Device. The user  
must add a software point (pseudo analog - in RIO CARE Plant) that can be mapped to the actual hardware input (RIO Plant)  
through the Custom Mapping function of E-Vision. The procedure described previously for adding an enthalpy ( 4 to 20 mA)  
sensor should be followed and instructs the user on adding the pseudo analog point in the RIO CARE Plant and using the

Common Operations  
The Excel 10 W7761A Device contains inputs and outputs, but no control software. All control that would be associated with  
the inputs and outputs in the W7761A would be accomplished though the Excel Zone Manager and would not be suitable for  
VAV control, temperature control, or any control function that would require less than a 30 second update rate. The analog and  
digital sensors could be shared or bound to other Excel 10 controllers on the E-Bus or Excel 5000 controllers on the C-Bus  
through the Excel 10 Zone Manager. This would allow the other Excel 10 controllers to use their physical inputs for monitoring  
other elements such as return humidity, IAQ, etc. to achieve better control.  
Room Temperature Sensor (RmTemp)

EXCEL 10 W7761A INPUT/OUTPUT DEVICE  
The T7770A,B,C,D wall module is the room space temperature sensor—(current feature that can be used with the RIO  
Device). When it is configured, it provides the temperature input that can be shared with the W7750 or W7751 controllers. If  
there are multiple space sensors in a area controlled by one W7750 CVAHU, then the space temperatures can be wired into  
the W7761A controller and mapped to the Zone Manager. The Zone Manager can average all of the space temperatures and  
then have that value can be bound to the W7750 controlling that area.  
Window Sensor (StatusWndw)  
The digital input for a window contact can be wired into the W7761A device and then bound to a W7750 CVAHU to disable its  
temperature control algorithm if someone has opened a window or door in the room or area that the W7750 is serving. When a  
window is detected to be Open (digital input contacts Open equals window open), the normal temperature control is disabled,  
and the W7750 Controller enters the Freeze Protect mode. Freeze Protect mode sets the space setpoint to 50 °F (10°C) and  
brings on the fan and heat if the space temperature falls below this setpoint. Normal temperature control resumes on window  
closure.  
Dirty Filter Monitor  
The air filter in the air handler can be monitored by a digital input in the W7761A and an alarm issued by the Zone Manager  
when the filter media needs replacement. The two methods of monitoring the filter are:  
1. A differential pressure switch whose contacts are connected to a digital input on the W7761A and;  
2. A 2 to 10V differential pressure sensor wired to a voltage input on the W7761A. If the analog input sensor is used, its  
measured value 0 to 5 inw (0 to 1.25 kPa) is compared to a user-selectable setpoint in the Zone Manager, the  
comparison is done in the Zone Manager - valid range: 0 to 5 inw (0 to 1.25 kPa), and the Dirty Filter alarm is issued by  
the Zone Manager when the pressure drop across the filter exceeds the setpoint.  
Series 60 Modulating Control  
Series 60 Control is also commonly referred to as Floating Control. The Excel 10 W7761A Device can drive Series 60 type  
actuators to control a modulating damper or valve actuator. The W7761A device contains no control software, so these outputs  
would have to be bound to either the Zone Manager or other Excel 10 controllers. When floating control is used, the full-stroke  
motor drive time of the actuator must be entered into the configuration parameter DO1FlSpeed (for output 1), DO2FlSpeed (for  
output 2). When Floating control is configured, two digital outputs are required, so the user has to change the configuration  
parameter for the appropriate digital outputs.  
Pulse Width Modulating (PWM) Control  
The Excel 10 W7761A device can drive a PWM-type actuator to control a modulating actuator. The W7761A device contains  
no control software, so these outputs would have to be bound to either the Zone Manager or other Excel 10 controllers. PWM  
control positions the actuator based on the length, in seconds, of the pulse from the digital output. The controller outputs a  
pulse whose length consists of two parts, a minimum and a maximum. The minimum pulse time represents the analog value of  
zero percent (also indicates a signal presence) and the maximum pulse length that represents an analog value of 100 percent.  
If the analog value is greater than zero percent, an additional time is added to the minimum pulse time. The length of time  
added is directly proportional to the magnitude of the analog value. If PWM control is used, the configuration parameters for  
the PWM operation must be specified. These parameters are DO1PWMPeriod and PWMZeroScale, and PWMFullScale.  
Example: To find the pulse width of a valve actuator (for example stroke mid position - 50 percent) with the PWMZeroScale =  
0.1 seconds, PWMFullScale = 25.5 seconds, and the PWMPeriod = 25.6 seconds. There are 256 increments available, so the  
number of increments required for 50 percent would be (0.5 X 256) or 128. The time for each increment for this industry  
standard pulse time is 0.1 seconds. The pulse width is the minimum time (0.1 second) + the number of increments (128 times  
the seconds added 0.1) = 12.9 seconds. The W7750B Controller would command the valve output on for 12.9 seconds every  
25.6 seconds to maintain the valve position at 50 percent.  
Indoor Air Quality (IAQ) Override  
The Excel 10 W7761A Device can monitor an IAQ sensor and that input can be bound to a W7750 CVAHU Controller that  
supports an IAQ override feature, that upon detection of poor air quality in the space, allows the economizer dampers to be  
opened above the standard minimum position setting to a value set in EconIAQPos (parameter located in W7750). Two  
different methods of detecting poor air quality are supported, The first is by using an IAQ switch device connected to a digital  
input on the W7761A Device, where a contact closure indicates poor air quality. This digital input would then be bound to the  
W7750 Controller that is serving the area being monitored and would initiate the IAQ override mode. The second is through an  
analog input that connects to a CO2 Sensor (0 to 10V). The measured value of CO2 from this sensor (0 to 2000 ppm) is  
mapped into the Zone Manager where it is compared to a setpoint (parameter located in the Zone Manager). When the CO2  
level is higher than the setpoint, the Zone Manager can initiate an IAQ alarm. A pseudo digital point in the Zone Manager can  
be bound to the W7750 CVAHU Controller which can initiate the IAQ override mode.

DestOut1Cmd: DestOut1Cmd through DestOut8Cmd corresponds to DO1 through  
DO8. Refer to the Eng. Units/States column for DO1Type for the enumerated  
values that can be assigned to any output channels.  
Note that a selection of FLOAT means that the two DO channels are used for  
output. RIO assumes that the tool makes the proper assignment of enumerated  
values to DO1 through DO8 and also takes the responsibility to avoid assignment  
of multiple or overlapping commands on the same output channels. An example of  
the relationship between nviRemoteCmd and ncirioIoSelect is discribed below:  
RIO is receiving a command to DestOut4Cmd. This can be mapped as one of the  
three output types (Discrete, Modulate, Float_Open, or Float_Close) by DO3Type.  
If the user selects an enumerated value of Discrete2 for DO3Type, this value would  
be stored in (DO2). Then the DestOut4Cmd will command DO2.

nviInUse is used by a management node to indicate to all other management  
nodes that it is logged on, to the Excel 10 node and that they should not try to  
interact with any of the Excel 10s network variables. Before the management node  
reads or writes any network variables, the management node checks nviInUse for  
a zero value meaning no other management nodes are already logged on and that  
a management node may log on, to the node. Then the management node writes a  
number, 1 through 65534, to nviInUse and periodically writes the same value to  
indicate that the management node is still logged on. If there are no writes made to  
nviInUse for approximately 60 seconds, then the Excel 10 resets nviInUse to zero  
to automatically log off the management node. Before interacting with any network  
variables, the management node verifies that the nviInUse has not changed. The  
management node logs off by writing 0 to nviInUse.  
During power up, an application restart, or return to on-line from off-line, the Excel  
10 sets nviInUse to 65535 to indicate to the management node that it has returned  
to on-line.

AlarmNode: is the LonWorks node number (in domain entry 1 of the nodes domain  
table) assigned to the node.  
AlarmSubnet: is the LonWorks subnet number (in domain entry 1 of the nodes  
domain table) to which the node is assigned.  
AlarmType: is the alarm type being issued. When an alarm condition is no longer  
TRUE, type is set to the sum of the alarm conditions numeric value and the  
RETURN_TO_NORMAL numeric value. The type also is recorded in  
AlarmTypeLog0 through AlarmTypeLog4. When a new alarm is detected, just the  
corresponding numeric value for the alarm is reported. Refer to table 9 (Excel 10  
Alarms) in the System Engineering Guide for all the error conditions that may be  
reported.

AlarmTypeLog0 (0, 1, 2, 3, 129, 130, 131, 255)  
A supervisory node may poll the AlarmTypeLog output for a short alarm history. The  
last five alarm reports sent via nvoAlarm are reported via AlarmTypeLog. When  
ALARM_NOTIFY_DISABLED is entered into the log, further alarms or return to  
normals are not entered into the log, until alarm reporting is again enabled. If  
nvoAlarm is bound and not being acknowledged, the last alarm report entered into  
the AlarmTypeLog is the one that was not acknowledged.  
See nvoAlarm and for related subjects.  
type ( n ) specifies the alarm that was issued via nvoAlarm. See nvoAlarm for the  
alarm types used in AlarmTypeLog. The newest alarm is reported in type( 0 ) and  
the oldest is reported in type( 4 ). When a new entry is made to the log, the oldest  
entry is lost.

ResSensor1Error(AI1): The nvoError is a polled output containing a list of the current  
errors detected by the node. A search for error conditions in the node is made  
periodically. A diagnostic tool may poll nvoError for all of the current errors. nvoError  
uses one bit for each possible error condition. nvoError contains all the detected  
current errors even though they may be suppressed for reporting by nvoAlarm.  
There is a correspondence between the error conditions and alarm types. nvoError  
includes sensor failure errors and input network variable failure detect errors. Any  
sensor failure errors result in a SENSOR_FAILURE alarm. Failure to receive any  
bound network variable periodically results in an INPUT_NV_FAILURE alarm.  
nvoError tells which sensor(s) or network variable(s) have failed. See nvoAlarm,  
AlarmTypeLog for related subjects.

ApplicationType identifies the current application number of the Excel 10.  
nciDeviceName is an 18 character field used to identify the node uniquely as one  
object at the site or project. The contents of the nciDeviceName is maintained by a  
management node. If nciDeviceName is all ASCII blanks, it is considered  
unconfigured.  
The time stamp of the last change to the Excel 10 application configuration. Time  
meets the ANSI C time stamp requirement specifying the number of seconds  
elapsed since midnight (0:00:00), January 1, 1970. It is represented in the Intel  
Format.  
VersionNumber identifies the version number of the Excel 10 application.

AIOutputRHigh: This is the equivalent temperature degrees F (degrees C) value for  
the resistance entered for AIResHigh. Using the resistance example for AIResHigh  
of 48,000 ohms, you would enter the equivalent temperature of 45.0 degrees F (7.2  
degrees C) for the AIOutputRHigh value.  
AIOutputRLow: This is the equivalent temperature degrees F (degrees C) value for  
the resistance entered for AIResLow. Using the resistance example for AIResLow of  
11,520 ohms, you would enter the equivalent temperature of 99.0 degrees F (37.2  
degrees C) for the AIOutputRLow value.  
AIResHigh: This is the highest resistance value of the user specified range for a  
custom resistive input as selected through E-Vision in the input Tab of the  
Application selection screen. The user can select between a PT3000  
(Custom_PT3000) or a 20 Kohm NTC (Custom_20 Kohm NTC) sensor. This value is  
specified in ohms with LSB in 10 Ohms. This means that if your high resistance  
value for a 20 Kohm NTC sensor was 48,000 ohms, 45.0 degrees F (7.2 degrees C),  
the value that would be entered for AIResHigh would be 4800 (the resistance value  
divided by ten).

specified in ohms with LSB in 10 Ohms. This means that if the low resistance value  
for a 20 Kohm NTC sensor was 11,520 ohms, 99.0 degrees F (37.2 degrees C), the  
value that would be entered for AIResLow would be 1152 (the resistance value

DO1PWMPeriod is a intermittent voltage pulse whose width varies in proportion to  
the desired actuator position. The PWM signal has three parameters that have to be  
configured in order for the output to function correctly. The period, is the overall pulse  
lenegth in seconds. The percent_time (signal presence) is the zero percent position  
of the actuator output. The actuator requires this signal (pulse width) sent once every  
period, so that it knows that it is still connected to the controller and where the zero  
position starts. The variable width (delta_time) portion is incremented in proportion to  
the signal percentage. There are 255 increments available (for example 0.1 second).  
Thus, the pulse width will be the minimum width (percent_time) plus the number of  
increments (delta_time/ 255). The smallest time that can be used with the RIO  
controller is 0.1 second. An example stroke at mid position is: 0.1 second  
(percent_time) + 128 x 0.1 (255/0.5 - 50 percent position) = 12.9 seconds. The period  
would equal the percent_time plus the delta_time (for example 0.1 seconds) + 255 x  
0.1 seconds = 25.6 seconds.

DestManMode: is an input which is used to manually set the physical outputs.  
DestManMode remains unchanged until another mode has been commanded or an  
application restart has been performed. The valid enumerated values are:  
MODE_ENABLE enables the node so that the RIO controls the physical outputs as  
the normal mode. MODE_ENABLE is the default state after power is restored or an  
application restart occurs. If the mode was MANUAL and DestManMode is set to  
MODE_ENABLE, the node then goes through application restart.  
MODE_DISABLED sets the node into the DISABLED mode. The alarm  
NODE_DISABLED is initiated, and the physical outputs are turned off. The physical  
inputs, network variable inputs, and network variable outputs are still functioning  
when the node is in the DISABLED mode.  
MODE_MANUAL sets the node into the MANUAL mode. The alarm  
NODE_DISABLED is initiated, and the physical outputs are controlled manually as  
commanded by DestManMode. The nodes configuration variables and  
DestManMode are used to set valves, dampers, and/or digital output to the desired  
manual positions or state(s). The physical inputs, network variable inputs, and  
network variable outputs are still functioning when the node is in the MANUAL mode.  
SUPPRESS_ALARMS causes AlarmType to be set to ALARM_NOTIFY_DISABLED,  
and AlarmTypeLog to no longer record alarms. If alarms are suppressed,  
UNSUPPRESS_ALARMS causes AlarmType and AlarmTypeLog to be returned to  
reporting alarms. See nvoAlarm for more details. All unspecified values are the same  
as MODE_ENABLE.

Appendix D. Q7750A Excel 10  
Zone Manager Point Estimating Guide.  
Memory size approximation is shown below: (all sizes in bytes)  
When memory size is less than 110,000 bytes, the size is OK.  
When memory size is between 110,000 and 128,000 bytes, the application may be too large. The user must expect to reduce  
the application complexity, reduce the number of attached Excel 10s or distribute the Excel 10s over more than one Zone  
Manager.  
When memory size is greater than 128,000, the size is too large. The application size must be reduced as described above.  
Approximate Memory Size Estimating Procedure.  
1. Determine the number of points per controller required at the Central (for example, XBS).  
NOTE: All remaining points that are not mapped can be accessed through the Direct Access feature.  
2. Calculate the number of Excel 10 Zone Manager program points that are used in control logic and in the switching table.  
3. Estimate the program complexity of the Zone Manager (one of three levels).  
a. No time programs, control logic, or switching tables.  
b. 10K of control logic (one time program, five switching tables, and five control loops).  
c. 20K of control logic (multiple time programs, ten switching tables, and ten control loops).  
Use Fig. D-1 to determine the number of Excel 10s that can be connected to the Zone Manager.  
NOTE: More than 60 Excel 10s requires a Router.  
4. Repeat for each Q7750A Excel 10 Zone Manager in a project.  
(A) NO TIME PROGRAM,  
NO CONTROL LOOPS,  
NO SWITCHING TABLES.

Fig. D-1. Point capacity estimate for Zone Manager.  
The exact equation for calculating memory size follows:  
Memory size = 21,780  
+ 4096 (in case of a time program).  
+ CARE Control Program.  
+ 14 x time points x Excel 10 units.  
+ 50 x Excel 10 units.  
+ map complexity x Excel 10 units x mapped points.  
+ 57 x C-Bus points.  
+ 7488 x Excel 10 types.  
Where:  
Time points = number of switch points in time program per Excel 10.  
Excel 10 units = number of attached Excel 10s.  
C-Bus points = including mapped points and others; for example, remote points.  
Mapped points = number of mapped points per Excel 10,  
including One-to-Many and Many-to-One  
mechanism.  
Excel 10 types = number of different Excel 10 types (currently three)  
Map complexity =  
20 = using One-to-Many and not using  
points with read/write.  
30 = average.  
45 = many points with read/write ability.
