Comfort Controller Processor (PCB1) —

The central processing unit for the OMNIZONE system

control is the Comfort Controller 6400. The Comfort Control-

ler provides general purpose HVAC (heating, ventilation and

air conditioning) control and monitoring capability in a stand-

alone or network environment using closed-loop, direct dig-

ital control. The Comfort Controller 6400 has been pre-pro-

grammed to work in either stand-alone or CCN (Carrier Com-

fort Network) system installations.

The CC6400 processor is designed to provide heating and

cooling control, loop control, scheduling, and custom program-

ming. The main processor provides 16 field points (8 input and

8 output). Additional points are provided by the I/O modules

described on page 2. Table 1 lists the control inputs and outputs

for all CC6400 modules.

(IO BUS

COMMUNICATIONS)

REMOTE OCCUPANCY CONTROL (PCB1) — This con-

trol is a field located switch, controller or timer input which,

when activated, tells system when to switch from Unoccupied

to Occupied mode.

YELLOW

(CNN BUS

COMMUNICATIONS)

When in Occupied mode, the unit turns on the supply fan

and controls supply fan speed to maintain a duct static set point

measured at the Duct Static Pressure Sensor (DSP). The unit

operates to provide conditioning to a set point. When in

Unoccupied mode, the unit provides no cooling/heating, or

controls to a ‘setback’ set point.

FIRE ALARM (PCB1) — The fire alarm is a control voltage

input to the 50XJ unit, which causes the controller to shut the

system down in the event of a fire.

CONDENSER WATER FLOW SWITCH (50XJ

PCB1) — This thermal dispersion type flow switch if factory

installed, is located in the unit waterline to ensure that there is

waterflow before allowing the unit to start the compressor(s). If

no flow is detected, then compressor operation and economizer

cooling is avoided until waterflow is again detected. An

warning light (yellow) is provided during this state.

HEAT INTERLOCK OUTPUT (50XJ PCB2) — This output

is activated whenever heating is activated, commanding the

VAV dampers to operate in heating control mode.

Fig. 1 — CC6400 Control Module LEDs

Carrier Comfort Network Interface — The 50BV,XJ

units can be connected to the CCN (Carrier Comfort Network)

if desired. System elements are connected to the communica-

tion bus in a daisy chain arrangement. The negative pin of

each system element’s communication connector must be

wired to the respective negative pins, and positive pins on each

component must be connected to respective positive pins. The

controller signal pins must be wired to the signal ground pins.

Wiring connections for CCN must be made at the 3-pin plug.

At any baud rate (9600, 19200, 38400 baud), the number of

controllers is limited to 239 devices maximum. Bus length may

not exceed 4000 ft, with no more than 60 total devices on

any 1000-ft section. Optically isolated RS-485 repeaters are

required every 1000 ft.

NOTE: In order to this output to function, the Terminal

Occupied output must also be on.

TERMINAL OCCUPIED (50XJ PCB2) — Terminal Occu-

pied is activated to command VAV dampers to control to the

cooling set point. Terminal Occupied must be on along with

Heat Interlock for heating set point control to function.

EXTERNAL RESET INPUT (50XJ PCB2) — This modu-

lating input (0 to 10 vdc) allows remote adjustment (upward) of

the Supply Air Temperature (SAT) sensor set point. The default

External Reset Input setting is 55 F. This variable input can

raise the set point by up to 20 F for a full-range input signal, or

to any point in between.

WATER ECONOMIZER COIL (50XJ PCB2) — This factory-

installed option contains a water-to-air coil, two (2) electronic

motorized water valves, and related piping. Control of the water

economizer also requires a Mixed/Return Air Temperature

Sensor, a Condenser Water Inlet Temperature Sensor and an

Economizer Freezestat safety switch.

The electronic motorized water valves are each controlled

by the unit controller via separate 4 to 20 mA variable signals

to define variable valve position.

The Mixed/Return Air Sensor (MA_RA) is an air

temperature sensor located in the unit, between economizer

coil and evaporator.

The Condenser Water Inlet Temperature Sensor (CWT) is

located at the unit water inlet connection. This sensor receives

input power from the unit main controller and provides a linear

variable 1 to 5 vdc signal back to the controller. The full

temperature range is 32 to120 F.

The 50XJ units can be connected to two types of building

water systems: variable and fixed or constant flow control. In

either case, the economizer water valves are opened whenever

there is a call for Cooling and the Inlet Water Temperature is

colder than the Econ Start Set Point in the custom configuration.

NOTE: Carrier device default is 9600 baud.

The CCN Communication Bus wiring is field-supplied and

field-installed. It consists of shielded three-conductor cable

with drain (ground) wire. The cable selected must be identical

to the CCN Communication Bus wire used for the entire

network. See Table 2 for cable recommendations.

NOTE: Conductors and drain wire must be at least 20 AWG

(American Wire Gage), stranded, and tinned copper.

Individual conductors must be insulated with PVC, PVC/

nylon, vinyl, Teflon, or polyethylene. An aluminum/

polyester 100% foil shield and an outer jacket of PVC,

PVC/nylon, chrome vinyl, or Teflon with a minimum

operating temperature range of –20 C to 60 C is required.

The communication bus shields must be tied together at

each system element. If the communication bus is entirely

within one building, the resulting continuous shield must be

connected to ground at only one single point. If the communi-

cation bus cable exits from one building and enters another

building, the shields must be connected to the grounds at a

lightning suppressor in each building (one point only).

Optional and Field-Installed Accessory Sensors/

Devices — The 50XJ unit can be ordered with options and

accessories that add functionality and control. These options

and accessories are controlled by the CC6400 system as

described below.

NOTE: The CC6400 Control software includes all PCB1

functions, and most of the sensors/devices associated with

those functions are factory installed. However, some PCB1

sensors/devices must be field-connected to the proper terminal.

PCB2 devices are field-installed accessories. The CC6400

software includes these functions, but the actual sensor/device

must be installed and wired in the field. PCB3 is an accessory

control module. All PCB3 sensors/devices and software are

field-installed.

Dependencies — Water Economizer option is enabled, and

Fan is On, and Inlet Water Temperature is below set point; or

from “Remote Scheduler,” or from “Remote Linkage.”

Economizer mode is switched to Off or no start if: there is

no condenser waterflow, Fire Input is On, Fan is not On, or Un-

occupied mode is On.

Variable Waterflow Systems — Whenever water economizer

is off, the economizer flow control valve is fully closed, and the

reverse flow valve directly to the condenser is fully open. Upon

engagement of the water economizer, the economizer flow con-

trol valve shall be controlled to maintain the MA_RA located

between the economizer coil and the DX cooling coil, at a tem-

perature near the supply air set point. The the reverse flow valve

will be controlled in reverse of the economizer flow control

valve’s position. The following formula is an example: Reverse/

Head Press Ctrl output = 100 – two-position/Econo output.

Constant Building Waterflow Systems — Constant waterflow

configurations use two (2) water valves, only one of which is

in the main water supply pipe. The second valve is located in a

bypass pipe to the main outlet water pipe branched off of the

supply pipe immediately ahead of the first valve. This valve is

same type, but normally closed and is controlled in unison with

the first valve, but opposite position, such that the total opening

of the 2 valves always equals 100%.

VFD BYPASS (50XJ PCB2) — The VFD Bypass option

provides backup for the VFD Drive in VAV units. It uses a

manually operated rotary switch, which includes a series of

high voltage contacts. The bypass is a direct input to the unit

controller, and will be activated via a switch on the unit front

panel. When manually activated, the rotary switch takes the

VFD out of the fan power circuit and provides the 3-phase

power directly to the fan motor, running it at constant speed. A

low voltage control circuit ensures that the unit controller pro-

vides a signal to allow all VAV dampers to open fully before

the fan is turned on (at constant/full speed). A blue indicator

light located on the front of the unit indicates that the VFD By-

pass is active. A High Duct Static Switch (HDS) shuts the fan

down if duct static exceeds a maximum setting.

When the unit is off, both valves are closed.

Constant Waterflow Systems — Control of the economizer

flow control valve is same as for variable waterflow systems.

Control of the reverse flow control valve position will inversely

track the economizer flow control valve, such that the total sum

of the two valves open positions always equals 100%. The only

difference between the variable waterflow system and the

constant waterflow system is that for the constant flow system

when the unit is off, the economizer valve will be closed and

the reverse flow control valve will be open.

WATER ECONOMIZER COIL (50BV) — For the 50BV

unit, this factory-installed option contains a water-to-air coil, a

two-position diverting valve, and related piping. The water econ-

omizer is controlled by an Aquastat and a return-air thermostat.

VENTILATION OUTPUT (50XJ PCB2) — The ventilation

output is controller output signal (available for field connection)

to a field-supplied ventilation damper(s). This signal is activated

whenever the unit is in the occupied mode.

SPACE TEMPERATURE SENSOR (50XJ PCB2) — A field-

supplied Carrier space temperature sensor is required to

maintain space temperature in sensor mode.

SUPPLY AIR RESET (50XJ PCB2) — Supply air temperature

set point may be reset using either the SPT or MA_RA.

HEATING COILS AND VALVE (50XJ PCB2) — Water or

steam heating options are factory installed. Each includes a

motorized, variable control water or steam flow control valve,

which can be factory supplied for field installation outside the

unit. Installed in the water or steam inlet pipe, this valve is

wired to the unit main controller and operates on a 4 to 20 mA

signal. A Heating mode PID control is needed to control the

valve position (i.e., coil heating capacity) variably between 10

and 100%. The PID will control a set point to + 1° F; for VAV

Units this set point is at the Supply Air Temperature Sensor, or

as communicated from a remote thermostat.

SUPPLY AIR RESET (50BV) — Reset is provided by a

field-installed temperature sensor.

EXHAUST FAN CONTROL OUTPUT (50XJ PCB2) — This

output is activated whenever the unit is in the Occupied mode.

This is a modulating output that controls based on the Building

Pressure Input set point.

CONDENSER WATER PUMP/WATER TOWER (50XJ

PCB2) — This output (provided for field connection) is used

to control condenser water flow. Either an On/Off signal or a

variable output may be required for this feature.

HEAD PRESSURE CONTROL (50XJ PCB2) — Head Pres-

sure Control is required for unit installations that will

experience entering condenser water temperatures of 55 F or

lower.

PHASE LOSS/REVERSAL PROTECTION SWITCH

(50XJ PCB2) — This switch monitors VFD/Fan Motor sup-

ply leads to detect phase loss or reversal. If the switch detects

improper phasing, an input is sent to the unit controller, which

shuts the unit down. After a time delay, the controller attempts

to restart the unit.

A phase loss/reversal switch may be installed in the unit to

detect over/under voltage conditions and phase loss or reversal.

When the switch opens, the controller outputs are forced to off

with Safety forces, the alarm output will close and the red

alarm light will be lit. A system alarm will be generated and

displayed on the unit keypad. Unit reset is automatic when the

voltage and power phases have been restored.

FREEZE THERMOSTAT (FREEZSTAT) (50XJ PCB2) — The

Economizer Freezestat, used in conjunction with an optional

water economizer coil or heating coil, is a factory installed

averaging (capillary tube) air temperature sensor positioned in

the unit inlet airstream.

If the freeze protection switch contacts open the ventilation

request output will be closed for 15 minutes and the warning

light will light. If the freeze protection switch contacts are still

open after 15 minutes the supply fan will be stopped, all

compressor cooling will stop, the economizer valve will open

to 100%, the pump request output will remain on, and the

alarm light will light. This will maintain condenser water flow

through the coil to prevent freezing the coil while stopping all

other operations that could have contributed or will be affected

NOTE: Head Pressure Control is not needed or used in

conjunction with a Water Economizer. A refrigerant pres-

sure transducer will monitor head pressure on compressor

circuit 1, allowing the unit main controller to regulate water

flow rate in the main water line entering the unit; i.e., flow

to all condensers. (Water header design to the condensers

will be optimized such as to provide relative flow rates to

each condenser based on its compressor capacity, enabling

successful waterflow control at the main entering pipe.)

There are two possible water valving configurations, as

outlined below.

Pressure transducer input is factory installed in the

discharge line of compressor circuit 1. It is provided 5 vdc by

the unit main controller and returns a signal 1 to 5 vdc linearly.

The sensor’s range is 0 to 550 psig.

Water Valve(s) Control

Variable Building Waterflow Systems — Variable waterflow

configurations use only one water valve in the main water

supply pipe. The factory installed valve is a normally open

motorized variable control type. The valve is controlled by a

4 to 20 mA signal from the main unit controller using the

Reverse/Head Press Ctrl output, which modulates to maintain

the head pressure set point (Setpoint 04).

by the freeze condition. Unit reset is automatic when the

contacts on the freeze protection switch close again. The

contacts on the freeze protection switch open below 37 F.

to reset the 50XJ supply-air temperature. The controller will

scale the signal to provide 0 reset at 0 volts and 20 degrees of

reset at 10 volts. Wire the positive of the signal to the RESET

terminal and the negative to the C or common terminal.

as the 33ZCT55SPT sensor may be used. If the SPT

sensor is not installed and the MA_RA (mixed air/

return air) sensor is configured for return air, the 50XJ

unit will use this sensor to control supply air reset,

occupied heat, and unoccupied heating and cooling

See Fig. 4 for space temperature sensor averaging.

HOT WATER OR STEAM VALVE (HWV) (50XJ

PCB2) — The HWV terminal supplies the positive signal to

control a 4 to 20 mA hot water or steam valve for occupied and

unoccupied heat. Connect the common side of the valve to the

C terminal or an equipment ground.

SPACE TEMPERATURE SENSOR (50XJ PCB2) — The

CONTROLS AND FUNCTIONS

Using the Local Interface Display — The Local

Interface Device (LID) is a CCN operator interface that gives

the user the capability to view and modify all configuration and

service data for the CC6400 control system. The LID also

allows the user to override all point display and maintenance

data.

MENU STRUCTURE — The LID operates on a hierarchy of

four levels (menus).

The top level contains the LID’s major functions. Each

function has a corresponding key on the LID. For an explana-

tion of each function key, refer to Table 3.

The second level separates the major functions (items) into

types with corresponding type numbers that can be used for

quick access.

The third level gives the user the capability to access each

occurrence of an item. For example, the application may

require two DO (Discreet Output) — Analog Comparison

algorithms. Thus, the CC6400 Controller would have two

occurrences of the DO — Analog Comparison algorithm.

The fourth level gives the user the capability to access main-

tenance and configuration data associated with the selected

occurrence of the item.

DEFAULT SCREEN — Figure 5 shows the LID. The LID’s

screen provides the user with the 24-character controller name

and the controller’s current time, date, and alarm status. This

screen appears when the LID is powered up and communicat-

ing with the controller or there is no keyboard activity for

10 minutes.

OPERATIVE

KEYS

USE

Clear — performs three operations:

• Cancels a data entry before the user

presses Enter, thus leaving the current

value unchanged.

• Returns a forced point to automatic

control.

• Redisplays the previous menu level.

Enter — performs two operations:

• Selects the displayed item, thus displaying

either its maintenance or configuration

data, depending on whether the user is in

the Status mode or the Edit mode.

• Accepts the value entered in a configuration

decision as new configuration data or as a

force.

CLEAR

ENTER

Down arrow — displays the next configured

item or decision. When the last configured

item or decision is displayed, the LID

re-displays the first configured item or

decision. For example, when the user presses

the down arrow key while viewing the last

configuration decision of an algorithm, the LID

re-displays the first configuration decision.

Up arrow — Displays the previous configured

item or decision.

Table 5 — Numeric Keys

OPERATIVE

KEYS

USE

Numeric keys

Performs two operations:

• Separates items, such as an algorithm from

its occurrence or hours from minutes.

• Serves as a decimal point in numeric values.

KEYPAD AND DISPLAY — The LID consists of a keypad

with 8 function keys, 4 operative keys, 12 numeric keys (0 to

9,., and -) and a two-line, alphanumeric liquid crystal display

(LCD). Each line on the LCD can display up to 24 characters.

See Fig. 5. Table 4 defines the purpose of the LID’s operative

keys. Table 5 defines the purpose of the LID’s numeric keys.

Performs two operations:

• Negates the value of numeric keys.

• Clears current data entry value any time it is

not the first key pressed during the data

entry sequence.

Table 3 — LID Function Keys

VIEWING MODES — The user can view items in either the

Status (maintenance) mode or the Edit (configuration) mode.

OPERATIVE

USE

KEYS

Status Mode — When the user first powers up the LID, it

displays the CC6400 controller items in Status (maintenance)

mode. The user may view the current value or status of an item

in Status mode without actually logging on to the Controller.

Knowing the current values or status of items can be useful

when troubleshooting. For example, the user could determine

if a point was forced.

Status — gives access to maintenance

values and configuration data for points.

Alarm — gives access to maintenance

and configuration data for alarms.

History — gives access to maintenance

and configuration data for history system

functions.

NOTE: Not all items have maintenance data. If the item you

select does not have maintenance data, the LID will display

“No maintenance.”

Accessing Items in Status Mode — The user can access

maintenance data in Status mode in two ways:

Service — gives access to maintenance

and configuration data for service system

functions.

Setup — gives access to configuration

data for setup system functions.

Schedule — gives access to maintenance

and configuration data for schedules.

Algorithm — gives access to maintenance

and configuration data for AO, DO, and global

algorithms. It also gives access to BEST ++™

custom programs.

To perform the Run Test:

1. Turn unit power on.

Automatic Run Test — The 50BV,XJ unit controls are

programmed with an automatic run test that checks connection

and operation of major components. To perform the run test:

Verify that the control display (LID device/System Monitor)

interface cable is connected to internal jack on main controller;

that the fire alarm/shutdown switch input (FSD) has a factory

jumper or field input; that Bypass (if installed) is set in the

DRIVE position; and that the Local/Off/Remote switch is set to

the REMOTE position.

NOTE: When the Local/Off/Remote switch is in the

REMOTE position, the controller time schedule is pre-set

(from the factory) as unoccupied. This means that the unit

will not turn on until the run test is enabled. However, if the

controller schedule has already been modified in the field,

and the current time of day is occupied, then the supply fan

will start. The run test will shut the fan down when it

OPERATION

Occupancy Determination — The OMNIZONE™

controller can determine occupancy in many ways. Local occu-

pancy is determined by either a local schedule contained in the

CC6400 controller, the use of the ROCC discrete input point or

by setting the Local/Off/Remote switch to Local. In order for

the CC6400 schedule or ROCC point to function the Local/

Off/Remote switch must be set to Remote.

When the OMNIZONE unit is connected to a Carrier

Comfort Network and the Local/Off/Remote switch is set to

Remote, the controller occupancy can be determined by a

Network Group schedule, a Network Global schedule, or via

Linkage from a linkage device such as a ComfortID™ linkage

master.

If the Return/Mixed air sensor is in the mixed airstream and

configured as such and there is no Space temperature sensor

installed and no Linkage, the Space Control Point will display

a default value of 75 F, which is above the default occupied

cooling set point and below the unoccupied cooling set point.

If this condition exists, supply air reset from a sensor and

unoccupied unit operation will not occur.

If the unit is configured to use a sensor for the Space

Control Point or if Linkage is active and the space has

unoccupied demand, the software point OKFAN will turn on

followed by the points TRMCT for air terminal control and

PUMP and TOWER to request condenser water flow and

temperature control. Approximately 20 to 30 seconds later the

SF point will turn ON and then the VFD output SPEED will

increase. If unoccupied demand is the reason the fan is on, a

control force will appear next to the OKFAN point. Otherwise

there should not be a force on that point.

If the fan is running due to unoccupied heating or cooling

demand, either the space temperature (if installed), return air

temperature or average linkage temperature must rise or drop

to within half way between the occupied and unoccupied set

points in order for the fan to turn back off.

Enabled by Switching to Local Mode — When the switch is

placed in the local mode the ROCC point will indicate enable.

If ROCC is ENABLED a software routine will override the

occupancy schedule so that TIMECLOCK will also turn on.

When ROCC is turned off the TIMECLOCK point will turn

off within 60 seconds.

Supply Fan Shutdown — If the unoccupied demand is satis-

fied and TIMECLOCK and ROCC are off and disabled,

OKFAN will turn off, SF_SFS will turn off, Tower and PUMP

will turn off, and then 5 minutes later the SF point will turn off

and the VFD speed will go to 0%.

During the 5-minute delay, the cooling and heating routines

become disabled. This delay allows a compressor that may

have just started to run for its 5-minute minimum on time with

the supply fan on. For example, if the staging routine had just

started Compressor 3 at the time the OK_FAN point changed

to OFF, the cooling routine would become disabled and com-

pressors 1 and 2 would shut off right away. Compressor three

would continue to run for its minimum on time of 5 minutes.

The fan continues running until all compressors meet the

minimum on time and run with a load, preventing them from

shutting down due to a safety.

Fan Control — All Variable Air Volume (VAV) units have

a Variable Frequency Drive (VFD) to provide variable fan

motor speed and thus variable airflow. Fan control turns the fan

on and off based on unit operating mode, and controls fan

speed to maintain a particular duct static pressure at a Duct

Static Pressure Sensor (DSP). The objective is to maintain a

reasonably constant supply-air exit velocity at VAV system

outlet grilles, regardless of damper opening positions. The duct

static pressure sensor is field-installed about /₃of the way

toward the “far end” of the ductwork. A High Duct Static

Switch (HDS) provides protection by shutting the fan down if

the duct static pressure exceeds a maximum setting.

For the 50XJ unit, a VFD interface display is mounted in

the front of the unit. A number of user-adjustable features can

be entered/changed using the keypad on the display. These

features described in detail in the Variable Frequency Drive

Control section.

Sequence of Operation — The following control

sequence of operation for the 50XJ,BV unit describes the

various sequences that occur depending upon the way an

operation is triggered and which software control points are

involved.

SUPPLY FAN — The Supply fan can be activated in any of

the following ways:

•

Unoccupied space or return air temperature demand.

Unoccupied Linkage demand.

Local Time Schedule (TIMCLOCK software point).

Remote Occupancy (ROCC software point).

By placing the remote-off-local switch in the local

mode.

•

Enabled by Schedule.

Supply Fan operation with Optional Bypass (50XJ) — If the

optional VFD Bypass is installed and the Bypass switch has

been turned to Bypass, and the access panel is in place, the

software point Bypass access panel secure BB_SAFE has been

turned to ON, and the unit operation switch has been placed

back in local or remote, then the bypass start stop point BPS_S

will follow the SF point when it turns on and off. The terminal

open point TRMOP will go on with the TRMCT point before

the fan starts.

COMPRESSOR COOLING — If the fan is on and there is no

demand for Heat, the equipment mode (MODE) will be

COOL, and Cooling (COOLOK) will switch to ENABLE.

If the unit is configured for variable flow the Reverse/Head

Pressure CTRL valve will open (otherwise it will already be

open), and if there is condenser water flow (CDWF is YES),

then the Fan + Condenser water flow point will become TRUE

and the Compressor Cooling (COMRES) point will switch to

Enable.

Once one of the above conditions exists, either TIME-

CLOCK or ROCC indicates ON or Enable. The software point

OKFAN will turn on followed by the points TRMCT for air

terminal control and PUMP and TOWER to request condenser

water flow and temperature control. Approximately 20 to

30 seconds later the supply fan (SF) point will turn ON and the

VFD output SPEED will increase. The SPEED point will

output a signal, determined by a PID calculation, based on the

duct static pressure DSP input and the Supply Static Pressure

set point in SETPT05.

Once the supply fan is running and the static pressure

increases above the Supply fan status set point in SETPT01, the

supply fan status point (SFS) will indicate ON and the software

point SF_SFS will indicate TRUE.

Enabled By Unoccupied Demand — A software point “Space

Control Point” will display the current value of the sensor used

to determine unoccupied demand. The EWT sensor provides

this function for the 50BV unit. The display is based on the

COMRES triggers the compressor staging routine that

controls the number of compressors energized. Units are

equipped with 4 compressors piped in separate refrigerant

circuits, and staged On/Off in a fixed sequential manner

(compressor no. 1 through compressor no. 4). The compressor

control routine uses a PID calculation to determine the percent-

age of cooling required, from 1 to 100%. Demand for the PID

calculation is determined from the supply air temperature and

the supply air set point (SETPT06).

NOTE: The reset from all methods may be limited to 10 F

or 15 F by changing the high end point of the custom

voltage input from the default (20 F) to 15 F or 10 F.

Either the return air or a space temperature sensor will be

used as the space control point. If this variable goes below the

Occupied High set point in the HEAT/COOL MODE AND

RESET set point (SETPT03), then for each degree that the

Space control point is below the set point value the supply air

set point will be reset by the value configured in the custom

configuration RESET RATIO.

If Linkage is active, for each degree that the average

occupied space temperature is below the average occupied cool

set point, the supply air set point will be reset by the amount

configured in the RESET RATIO. Reset will be limited to the

maximum value the custom voltage input RESET can display.

COOLING RESET (50BV) — The 5k ohm temperature sen-

sor will be used as the space control point. If this variable goes

below the Occupied High set point in the HEAT/COOL

MODE AND RESET set point (SETPT03), then for each

degree that the Space control point is below the set point value

the supply air set point will be reset by the value configured in

the custom configuration RESET RATIO.

Compressor cooling (COMPRES) will be turned off for any

of the following reasons:

•

There is no condenser water flow (CDWF is Off).

Economizer Freezestat (FREEZ) has been in alarm for

more than 15 minutes.

•

MODE changes to heat.

OK-FAN turns off during normal shut down.

During normal compressor operation the minimum on

time is 5 minutes and the minimum off time is 5 min.

ECONOMIZER COOLING (50XJ) — The unit diverts con-

denser inlet water flow through an optional economizer coil to

precool evaporator entering airflow. This occurs when there is

demand for the cooling, and the temperature at an Entering

Water Temperature (EWT) thermistor is colder than the

economizer start set point. Waterflow is controlled via two

electronic water flow valves. This option also incorporates an

Economizer Freeze Switch (EFS), located at the inlet of the

economizer coil.

Economizer water flow is in series with the condensers

allowing compressor operation while the economizer is

operating.

If the Fan is on, and there is no demand for heat then the

equipment mode (MODE) will be COOL and Cooling

(COOLOK) will switch to ENABLE.

HEATING (50XJ) — The controller is configured to control

two types of heat:

•

A modulating 4 to 20 mA output Hot Water Valve

(HWV) in the base unit, wired to the second module.

Four stages of staged heat wired to a third, accessory

module (PCB3).

•

For either method of heat to function, a space control point

must be configured in the custom configuration. This control

point comes from a return air sensor or space sensor, or from

the average space temperature received through linkage.

Whenever the space control point is below the occupied or

unoccupied heat set point the mode will change to heat and if

unoccupied the fan will be started. For linkage, this occurs if

the average space temperature is below the appropriate average

heat set point.

If the unit is configured for variable flow the Reverse/Head

Pressure CTRL valve will open (otherwise it will already be

open), and if there is condenser water flow (CDWF is YES)

then the Fan + Condenser water flow point will become TRUE.

If the entering-water temperature is below the Economizer

start set point in the configuration parameters table (Table 10),

then the Mod. Econ Enabled point (ECONOK) will change to

enable and the Economizer valve will modulate open to lower

the Economizer control temp to the supply air set point

(SETPT06) temperature. The economizer modulation is

controlled by a PID loop and the Reverse/Head pressure

control valve will modulate in reverse of the Economizer valve

using the formula MVLV = 100 – ECONO.

ECONOMIZER COOLING (50BV) — The unit diverts con-

denser inlet waterflow through an optional economizer coil to

precool evaporator entering airflow. If the entering-water

temperature is colder than the setting on the Aquastat, and the

return-air temperature is warmer than the setting on the return

air thermostat, the two-position diverting valve will direct

water to the economizer coil.

Both heat control routines use a PID to calculate a supply air

set point that will satisfy the heat demand in the space. The

modulating output and the staged outputs will both operate at

the same time to control an attached heat source, such as steam

valves or electric heaters, to provide the supply-air temperature

required.

The heat mode changes back to cool when the space control

point is back above the occupied heat set point. For linkage, the

mode changes back to cool when the average space tempera-

ture is back above the average occupied heat set point.

When unoccupied heat is enabled the fan will be stopped

and the heat turned off when the space control temperature is

more than halfway above the difference between the occupied

heat set point and the unoccupied heat set point. For example,

if the occupied heat set point is 70 and the unoccupied heat set

point is 60 the unit will come on for unoccupied heating below

60 F and turn off again above 65 F. The average occupied and

unoccupied set points are used when linkage is active.

HEAD PRESSURE CONTROL (HPC) (50XJ) — In instal-

lations where entering water temperature can fall below 55 F,

where a water economizer (described above) is not installed,

the HPC provides 1 or 2 electronic water flow control valves to

vary flow to the condensers. Controlling the water flow

maintains compressor discharge pressure above a minimum

value, ensuring sufficient refrigerant flow out of the condenser

and throughout the refrigerant circuit. Refrigerant pressure is

measured at compressor circuit no. 1 by a Discharge Pressure

Sensor (DPS).

Economizer water flow is in series with the condensers

allowing compressor operation while the economizer is

operating.

COOLING RESET (50XJ) — The controller can reset the

supply air set point using these three methods:

•

An external 0 to 10 volt input RESET

The value of the space control point

Linkage

The external 0 to 10 volt input reset is configured to produce

a 0 to 20 degree supply air reset over the 2 to 10 volt range. If

more than 1.8 volts is sensed on the input, this method of reset

takes priority over other methods.

Units not equipped with a water economizer can be ordered

with the reverse/head pressure control valve factory installed

and a pressure transducer located in the discharge line of

compressor no. 1.

When the condenser water temperature gets low enough to

cause the head pressure to drop, the valve will be modulated to

control the head pressure of all four compressors by varying

the water flow through the condensers.

When the unit is operating and the COOLOK software

point is enabled and the EWT gets below 60 F, the Head

software point will become enabled and the head pressure

control valve will modulate to keep the head pressure at the

head pressure set point (SETPT04). The default set point is

225 PSI and may be set from 200 to 250 PSI. The minimum

output value for the head pressure control algorithm is 40% in

order to maintain a minimum flow through the condensers. The

valve will modulate between 40 and 100%. Do not set the

minimum lower than 40% or the compressors may shut down

due to low flow, resulting in the high-pressure switch tripping.

VENTILATION REQUEST (50XJ) — The ventilation request

output will close a set of relay contacts to activate a ventilation

damper whenever the supply fan and supply fan status are both

true and the TIMECLOCK software point is on.

VAV TERMINAL OPERATION OUTPUT (50XJ) — The

VAV terminal control output (TRMCT) closes a set of relay

contacts to indicate to non-Carrier air terminals that the fan is

either forced on or is going to turn on. This signals the

terminals to open and start controlling to the desired CFM and

Temperature set points.

VAV TERMINAL OPEN OUTPUT (50XJ) — The VAV ter-

minal open output (TRMOP) closes a set of relay contacts to

command the air terminals to open to maximum CFM at times

when the fan is operating on the VFD Bypass.

PUMP AND TOWER OUTPUTS (50XJ) — The pump and

Tower outputs close a set of relay contacts to indicate that the

50XJ unit is in operation and may require condenser water

flow through the unit.

FIRE INPUT (FSD) — This is a normally closed input, which

when opened, deenergizes an isolation relay in the unit, opening

the input to the controller. When this input turns On, all control

outputs are immediately turned Off, including the fan. Unit

reset requires manual resetting at the main controller keypad.

DUCT HIGH STATIC INPUT (DHS) — This air switch

provides backup protection for the ductwork. It is factory

installed in the unit, wired to the unit main controller to receive

5 vdc. It is a normally open discreet switch, with adjustable

manual setting at the switch (range is 1 to 5 in. wg). Upon

switch closure, the controller immediately turns all outputs Off,

including fan, and then indicates an alarm both by turning On

its Alarm Output, Red Alarm light and via communications.

DIRTY FILTERS SWITCH (DFLTS) (50XJ) — This switch

measures the change (delta) in air pressure across the filters.

When the delta increases beyond the preset setting, a yellow

warning light will be lit, indicating that the filters need cleaning

or replacement.

The switch receives 5 vdc from the unit controller and

monitors air pressure delta across the return air filters. Switch is

normally open, with manually adjustable setting at the switch

between 0.5 and 1.5 in. wg. Upon closure, controller should

wait to assure closure for minimum 1 minute, then indicate an

alert via its non-critical alert output and via communications.

All other unit operation should remain normal.

COMPRESSOR OVERLOAD (COL)/SAFETIES — Each

compressor circuit is provided with a temperature overload

board (Copeland Protector Bd.), a Current Overload/Sensor

Board (COL), High Pressure Switch (HPS), Low Pressure

Switch (LPS), and Evaporator Freeze Switch (EFS). These

devices are wired in series to the contactor for each compressor.

Each such circuit is then wired through a common resistor board;

such that any one or more input(s) to the main controller allows it

to discern which compressor is not operating when it should be.

The Current Overload Board (COL) is located in the unit

control box, wired in the control power line for the compressor

pilot relay (which drives the compressor contactor), and

incorporates a current loop which monitors one leg of the

compressor power leads. This board is powered along with the

related compressor contactor.

Whenever the compressor current falls below a threshold

level (i.e., compressor not operating), it activates an on-board

relay which opens power to the compressor pilot relay (i.e.,

compressor contactor), and turns On a control power feedback

line to the unit controller, via the resistor board (described

above). Any one of the safety switches described herein will

cause this event. In the event this occurs, the controller shall

turn OFF this compressor, and start the next compressor in

sequence. After a 5-minute period, the controller shall restart

this compressor, and turn the other one off, as cooling demand

requires. If the ‘problem’ compressor then operates for 10 min-

utes of run time normally, the unit reverts to normal operation

and compressor sequencing. If not, and the same error occurs

again, this compressor shall be shut down and replaced with

the next compressor, as before, and held off for 10 minutes. It

shall then be restarted and the other compressor shut down, as

before. If it does not run successfully for 10 minutes of normal

run time again, it is shut down and replaced a third time. This

time it is held off for 15 minutes. If the “problem” compressor

does not operate successfully for the 10 minutes of normal run

time this third time, this compressor ONLY is shut down and

locked out for servicing. Alarm output (Red light) flashes and

then remains on.

BUILDING PRESSURE CONTROL (50XJ) — The building

pressure control output provides an analog 4 to 20 mA signal to

control return fan or exhaust fan speed. Fan speed is modulated

to maintain the building static pressure set point (SETPT07).

The control parameters for the building pressure set point

and building pressure are read and controlled in milliamps but

are converted to inches of water for ease of setting and display.

The range and low start values of the sensor selected should be

configured in the custom configurations screen. The raw sensor

value in milliamps will be displayed on the hardware point

BSP. The converted sensor reading in inches of H₂O will be

displayed at the software point BSP_IN. The set point input in

SETPT07 in inches of H₂O is converted to a raw milliamp set

point in SETPT08. The algorithm controls to the milliamp

values since the math required for control using the static

pressure in inches generates numbers too small to be used

given the range of the controller configuration parameters.

Diagnostic Features — The CC6400 provides a number

of features to help protect the unit and allow problem

diagnosis.

CRITICAL FAULT — The controller provides an output

(for field connection) to signal an external building systems

monitor or control that the unit is not operating properly and

has shut down. A red light mounted on the front of the unit

provides visual indication of this alarm condition.

NOTE: If the Local/Off/Remote switch is in the OFF

position, it is normal for the red alarm light on the display

panel to be lit, indicating that the unit is disabled.

NON-CRITICAL FAULT — The controller provides an

output for a yellow light, mounted on the front of the unit, that

indicates the need for minor maintenance or service.

HIGH-PRESSURE SWITCH (HPS) — This switch is located

in the discharge refrigerant line of each compressor, and is set

to open at pressures above 360 psig. It is wired in the 115 vac

control power line of the compressor contactor (in series with

the LPS and EFS), and activates the COL board (above) when

it opens.

LOW-PRESSURE SWITCH (LPS) — The Low-Pressure

Switch is located in the suction refrigerant line of each

compressor, and is set to open at pressures below 27 psig. It is

wired in the 115 vac control power line of the compressor

contactor (in series with the HPS and EFS), and activates the

COL board (above) when it opens.

EVAPORATOR FREEZE SWITCH (EFS) — This is a thermal

disk type switch, mounted on a return bend of the evaporator,

refrigerant circuit for which corresponds to each respective

compressor, and is set to open at temperatures below 28 F. It is

wired in the 115 vac control power line of the compressor

contactor (in series with the HPS, and activates the COL board

(above) when it opens.

The 7-character LED displays various values, depending

upon what mode is running.

•

In Standard Monitor mode: the LED displays the current

output frequency.

In Status Monitor mode: monitors the status conditions

and frequency command value setting.

In Setup mode: displays setup parameter titles and values.

In Program mode: displays parameter group titles, indi-

vidual parameter names, and parameter values.

During a trip: displays the trip title.

•

The appropriate local/remote LED, which is inset into the

speed control key, is lit when the unit is in Local or Remote

mode.

COPELAND PROTECTOR BOARD — This board is pro-

vided with each compressor, installed in the terminal box, since

these compressors do not have internal current protection. This

board activates at an overtemperature setting, and locks out

operation of the compressor for 30 minutes; there is no method

to over-ride or reset this timer. Due to this timing function,

please note that the compressor will not attempt to restart until

the third attempt described above.

ALARMS — Alarms can be provided via 4 methods; Unit

mounted Alarm Light (Red and Yellow), Keypad Display,

Network Communications, or a discreet Alarm Output to the

Field Low Voltage Terminal Strip. This field output circuit

includes an isolation relay and dry contacts. Alarms are

covered in detail in the Troubleshooting section.

The appropriate manual/auto LED, which is inset into the

run mode key, is lit when the unit is Manual or Auto mode.

When numeric data is shown on the LED display, the corre-

sponding unit indication LED will be lit. If no unit indication

LED is lit, the current data has no unit or the corresponding

unit does not exist on the display panel.

KEY FUNCTIONS — Refer to Table 11 for the functions of

each key on the keypad.

NON-TRIP MESSAGES — Non-trip messages are those that

may be displayed but do not cause a trip and are not recorded in

the fault history. Table 12 lists the non-trip messages with their

explanations.

TRIP MESSAGES — Trip messages and their causes are

shown in Table 13.

CLEARING A TRIP — A trip clear can be performed after

the cause of the trip has been removed. To perform a trip clear,

either switch off power to the inverter or use the following

procedure:

Press Stop/Reset. The display will show: CLr. Press Stop/Re-

set again. The display will show: 0.0, indicating that the trip is

cleared and the display will return to Standard Monitor mode.

If any key other than the STOP/RESET key is pressed at the

trip clear command prompt, the trip clear command is aborted

and the display returns to Standard Monitor mode (where the

trip title will be displayed flashing).The trip clear command

does not clear the recorded past faults.

50XJ Variable Frequency Drive Control — The

variable frequency drive is factory wired and programmed for

proper operation with the unit controls; no installation or

service adjustments are normally required. There is an interface

display for the VFD, independent of the main control display,

mounted on the front of the 50XJ unit.

The VFD default conditions at unit power up are: “AUTO”

run mode, “REMOTE” speed control, and “OFF” in the LED

display. When the fan is operating, the LED displays the output

frequency in Hz.

OPERATING KEYPAD — The keypad allows users to en-

able or disable the keypad, input commands from the keypad,

and monitor drive operation. Fig. 6 shows the operating panel

keypad layout and the locations of the keys and display LEDs.

Standard Diagnostic Features, Alarm and

Warning Lights

DUCT HIGH STATIC INPUT (DHS) — This air switch

provides over pressurization protection for the ductwork. It is

factory installed in the unit. The switch is a normally open

switch, with adjustable manual setting (range is 1 to 5 in. wg

default setting is 3.0 in. wg). Upon switch closure, the control-

ler outputs will be forced to off with safety forces, the alarm

output will close and the red Alarm light will be lit. A system

alarm will be generated and displayed on the unit keypad. Unit

reset is automatic when the duct pressure is again below the

switch setting minus the device hysteresis.

COMPRESSOR MULTIPLEX (MUX) BOARD — A re-

sistance board is used to generate a variable voltage input to the

controller to determine compressor status. If the voltage output

from this board gets out of the acceptable range the controller

outputs will be forced to off with safety forces, the alarm

output will close and the red Alarm light will be lit. A system

alarm will be generated and displayed on the unit keypad. Unit

reset is automatic when the Mux board has a valid reading

again. The valid range is between 1.5 and 10 vdc. The table

below indicates what voltages correspond to the compressor

status indicated in the controller.

SUPPLY AIR TEMPERATURE SENSOR FAILURE — If

the supply air temperature sensor fails and indicates either

245 F from a short or -40.0 F from and open sensor the control-

ler outputs will be forced to off with safety forces, the alarm

output will close and the red Alarm light will be lit. A system

alarm will be generated and displayed on the unit keypad. Unit

reset is automatic when the supply air sensor has a valid

reading again.

DUCT STATIC PRESSURE SENSOR FAILURE — If the

duct static pressure sensor fails and indicates either 5.0 inches

from a short or 0.0 inches from and open sensor the controller

outputs will be forced to off with safety forces, the alarm

output will close and the red Alarm light will be lit. A system

alarm will be generated and displayed on the unit keypad. Unit

reset is automatic when the supply air sensor has a valid

reading again.

FIRE/SHUTDOWN INPUT (FSD) — This is a normally

closed input, which when opened, deenergizes an isolation

relay in the unit, opening the input to the controller. When this

input turns opens, all control outputs are immediately turned

off, including the fan. Fire forces will be displayed on the

outputs. Unit reset is automatic when the FSD input is closed

Table 21 — Compressor MUX Board Voltages

A phase loss reversal switch may be installed in the unit to

detect over, under voltage conditions and phase loss or reversal.

Upon switch opening, the controller outputs will be forced to off

with safety forces, the alarm output will close and the red Alarm

light will be lit. A system alarm will be generated and displayed

on the unit keypad. Unit reset is automatic when the voltage and

power phases have been restored.

ECONOMIZER COIL FREEZE PROTECTION SWITCH —

This switch is installed in the 50XJ unit when the economizer

coil is provided. In the event the freeze protection switch

contacts open, the ventilation request output will be closed for

15 minutes and the Warning light will light. If the freeze

protection switch contacts are still open after 15 minutes, the

supply fan will be stopped, all compressor cooling will stop,

the economizer valve will open to 100%, the pump request

output will remain on, and the Alarm light will light. This will

maintain condenser water flow through the coil to prevent

freezing the coil while stopping all other operations that could

have contributed or will be affected by the freeze condition.

Unit reset is automatic when the contacts on the freeze

protection switch close again. The contacts on the freeze

protection switch open below 37 F.

SUPPLY FAN STATUS — Supply fan status is determined

by the duct static pressure sensor. If the fan is operating and a

fan speed signal is sent to the variable frequency drive, the duct

static pressure must become greater than the supply fan status

high set point (SETPT01) for the supply fan status software

point to turn on. When the duct static pressure becomes lower

than the supply fan status low set point, the supply fan status

will indicate OFF. If at any time the commanded state of the

supply fan does not agree with the supply fan status for more

than a minute, a supply fan status warning will be issued and

the warning light will be lit.

COMPRESSOR STATUS — Compressor status is determined

from the compressor MUX voltage input to the OMNIZONE

controller. If at any time the compressor status indicates off for

more than 30 seconds when the compressor commanded state

is on, the compressor will be turned off with a safety force and

the controller will try to start the compressor after five minutes.

If the compressor status does not indicate on for more than

30 seconds then the compressor will be turned off again with a

safety force for ten minutes. The controller will then try to

restart the compressor a second time. If the compressor status

does not come on within 30 seconds the compressor will be

turned off for 15-minutes this time. After the 15-minute delay

the controller will try to restart the compressor for a third time.

If the compressor does not start it will be locked out for this

operating cycle and will not be restarted until the OMNIZONE

controller goes through an off cycle where the cooling and

supply fan are shut down. When the compressor is going

through the three restarts or when it is locked out the Warning

light will be lit and the specific compressor alarm will be

indicated on the display and via communications. The three

strikes compressor test is reset automatically if the compressor

status comes on while the compressor is on.

CONDENSER WATER FLOW — This is an optional

switch that can be used with the OMNIZONE™ controller. A

thermal dispersion flow switch detects water flowing past the

sensor element and closes normally open contacts that energize

a relay with normally open contacts to the unit controller. If no

flow switch is installed, a jumper must be in place to indicate

that there is water flow all the time in order for the economizer

and compressors to operate. A configuration decision is used to

indicate if a flow switch is installed and disable alarms from the

flow switch. When the flow switch is installed, the controller

will check for water flow when flow is requested for unit

operation. The controller will also test or to see if there is water

flow when the unit is not operating. If there is no flow when

the unit is operating or if there is flow when the unit is not

operating, the warning relay will energize and the yellow light

will be lit. If only loss of flow indication is desired, the

configuration for the flow switch may be set to no and the

controller will only energize the warning relay and turn on the

yellow light if there is a loss of flow while the unit is in

operation.

DIRTY FILTERS INPUT — This air pressure delta switch is

factory installed in the 50XJ unit. It receives 5 vdc from the

unit controller and monitors air pressure delta across the return

air filters. Switch is normally open, with manually adjustable

setting at the switch between 0.5 to 1.5 in. wg. Upon closure,

controller should wait to assure closure for minimum 1 minute,

and then indicate an alarm both via its Alarm Output and via

communications. However, all other unit operation should

remain normal.
