These machines are constructed for maximum operator safety when used under standard
operating conditions and when recommended instructions are followed in the maintenance
and operation of the machine.
All personnel engaged in the use of the machine should become familiar with its operation as
described in this manual.
Proper operation of the machine promotes safety for the operator and all workers in its
vicinity.
Each individual must take responsibility for observing the prescribed safety rules as outlined.
All warning and danger signs must be observed and obeyed. All actual or potential danger
areas must be reported to your immediate supervisor.
General Responsibility
No mater who you are, safety is important. Owners, operators and maintenance personnel
must realize that every day, safety is a vital part of their jobs.
If your main concern is loss of productivity, remember that production is always affected in a
negative way following an accident. The following are some of the ways that accidents can
affect your production:
• Loss of a skilled operator (temporarily or permanently)
• Breakdown of shop morale
• Costly damage to equipment
• Downtime
An effective safety program is responsible and economically sound.
Organize a safety committee or group, and hold regular meetings. Promote this group from
the management level. Through this group, the safety program can be continually reviewed,
maintained, and improved. Keep minutes or a record of the meetings.

Operator Responsibility
The operator’s responsibility does not end with efficient production. The operator usually has
the most daily contact with the equipment and intimately knows its capabilities and
limitations.
Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or
through a casual attitude toward machinery formed over a period of months or years. Your
employer probably has established a set of safety rules in your workplace. Those rules, this
manual, or any other safety information will not keep you from being injured while operating
your equipment.
Learn and always use safe operation. Cooperate with co-workers to promote safe practices.
Immediately report any potentially dangerous situation to your supervisor or appropriate
person.
Maintenance Responsibility
Proper maintenance is essential to safety. If you are a maintenance worker, you must make
safety a priority to effectively repair and maintain equipment.
Before removing, adjusting, or replacing parts on a machine, remember to turn off all electric
supplies and all accessory equipment at the machine, and disconnect and lockout electrical
power. Attach warning tags to the disconnect switch.
Be sure that all non-current carrying parts are correctly connected to earth ground with an
electrical conductor that complies with current codes. Install in accordance with national and
local codes.
When you have completed the repair or maintenance procedure, check your work, remove
your tools. Rigging, and handling equipment.
Reporting a Safety Defect
If you believe that your equipment has a defect that could cause injury, you should
immediately discontinue its use and inform the manufacturer.
The principle factors that can result in injury are failure to follow proper operating procedures
(i.e. lockout/tagout), or failure to maintain a clean and safe working environment.

2-1 Models Covered in This Manual
This manual provides operation, installation, and maintenance instructions for 7-Pump, 50D
& D Plus-Station Conveying Controllers. Model numbers are listed on the serial tag. Make
sure you know the model and serial number of your equipment before contacting the
manufacturer for parts or service.
The 7-Pump, 50D & D Plus-Station Conveying Controller is a programmable logic
controller, with 24 VDC or 115 VAC control circuit, easy-to-use touchscreen operator
interface terminal and optional audible/visual alarm.
2-2 General Description
Our material conveying systems create vacuum for the automatic conveying of most free-
flowing, dry, pelletized, or granular materials. Material characteristics determine the type of
equipment needed to convey the material.
A typical use for our equipment is an in-plant distribution system for plastic processing
plants.
Our central vacuum systems are as varied as the applications they service. The tubing and
equipment furnished in our system is designed to convey the material(s) specified at the time
of purchase at specific rates and distances.
We can advise you on your system capabilities based on system makeup, distance, material,
and conveying rates you want.
System capacity is directly affected by the pressure drop in the overall system, such as
number of material line bends, pipe length, Y-tubes, T-tubes, etc.
Use the minimum effective amount of vinyl flex hose to maximize material line efficiency.
Keep material lines as straight as possible. Refer to the Mechanical Components Product
manual (Part No. A0536580) for installation recommendations.
Note: Vacuum leaks occurring anywhere in your system reduce capacity.

2-3 Standard Features
Mechanical Features
Time-fill Capability. The length of time allowed for material to drain from the station to its
receiver. During this time, the controller does not attempt to deliver any more material to the
station.
Volume-fill Capability. The length of time a station’s vacuum valve remains open to allow
material to be drawn in. The vacuum valve will close when material covers the station’s
volume-fill proximity sensor or this time elapses, whichever comes first.
Vent Valve Output. The vent valve protects the pump motor from damage during high
vacuum conditions if an undetected failure of the vacuum switch should occur. The vent
valve limits system vacuum by allowing a plunger in the valve to shift and vent the pump.
Closed-Loop Conveying. This feature allows material to be conveyed and processed
without being contaminated by outside influences (such as dust, other materials, etc.).
Common Purge Valve Output Control for Each Pump. This feature allows any remaining
material to be cleaned out of the vacuum pump or station.
Local Blowback Filter Cleaning Outputs. When this feature is enabled, the controller
periodically sends compressed air backward through the pump’s air filter to dislodge
accumulated dust and debris.

2-5 Safety Devices and Interlocks
This section includes information on safety devices and procedures that are inherent to the
Controller. This manual is not intended to supersede or alter safety standards established by
the user of this equipment. Instead, the material contained in this section is recommended to
supplement these procedures in order to provide a safer working environment.
At the completion of this section, the operator and maintenance personnel will be able to do
the following:
•
•
•
Identify and locate specific safety devices.
Understand the proper use of the safety devices provided.
Describe the function of the safety device.
Safety Circuit Standards
Safety circuits used in industrial systems protect the operator and maintenance personnel
from dangerous energy. They also provide a means of locking out or isolating the energy for
servicing equipment.
Various agencies have contributed to the establishment of safety standards that apply to the
design and manufacture of automated equipment. The Occupational Safety and Health
Administration (OSHA) and the Joint Industrial council (JIC) are just a few of the
organizations that have joined with the plastics industry to develop safety standards.
Every effort has been made to incorporate these standards into the design of the controller;
however, it is the responsibility of the personnel operating and maintaining the equipment to
familiarize themselves with the safety procedures and the proper use of any safety devices.
Fail Safe Operation
If a safety device or circuit should fail, the design must be such that the failure causes a
“Safe” condition. As an example, a safety switch must be a normally open switch. The switch
must be held closed with the device it is to protect. If the switch fails, it will go to the open
condition, tripping out the safety circuit.
7/50D Plus or 7/50D Controller
Chapter 2: Functional Description
12
Download from Www.Somanuals.com. All Manuals Search And Download.
At no time should the safety device fail and allow the operation to continue for example, if a
safety switch is guarding a motor, and the safety switch fails, the motor should not be able to
run.
Safety Device Lock-Outs
Some safety devices disconnect electrical energy from a circuit. The safety devices that are
used in this Controller are primarily concerned with electrical power disconnection.
WARNING! Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air)
sources prior to servicing the 7-Pump, 50D & D Plus-Station Controller. Failure to
do so may result in serious injury. No one but the person who installed the lockout
may remove it.

3-1 Uncrating
7-Pump, 50D & D Plus-Station Controllers are shipped mounted on a skid, enclosed in a
plastic wrapper, and contained in a cardboard box.
1. Pry the crating away from the skid.
Note: Remove the nails holding the box to the skid and lift the box off
carefully; avoiding staples in the 1’ x 4’ wood supports. Cut the steel
banding.
2. Use a pry bar to remove the blocks securing the unit to the skid.
3. Lift unit from sides, inserting forklift under the base. The forks must be equidistant
from the centerline of the unit and the unit must be balanced on the forks. Lift
slowly and only high enough to clear the skid. Use a pry bar if necessary to
carefully remove the skid from the unit.
4. Lower slowly.
3-2 Mounting the Control Panel
Note: Before you mount the panel, consider how you run wiring to the
KwikLink connectors, ArmorBlocks, vacuum hoppers, the filter cham-
ber atmospheric valve (if so equipped) and the pump motor starter(s),
vacuum switch(es), and vent valve(s).
Mount the control panel on a flat, vertical area. It should be a visible area that gives your
operator access to the control. The panel requires a low voltage power drop as listed on the
serial tag.
3-3 System Installation Overview
Installing the 7-pump 50-station controller is easy and straightforward. Because the system
uses networked distributed I/O modules, you’ll only need to run two cables for the entire
system.
The following is a typical installation sequence:
1. Run the black power and the grey data KwikLink™ flat cables from the start of the
system to the end, attaching them to vacuum tubing with nylon cable ties.
2. Set up mounting plates with tubing clamps; install KwikLink™ connectors and
ArmorBlocks onto mounting plates as required.
3. Install KwikLink connectors and ArmorBlock™ cable plates to mounting plates, and
install on vacuum tubing at each node location, just before a T-fitting or valve.
4. Install cable terminations.
5. Determine location of network system nodes, and set addresses for ArmorBlocks as
required.
6. Set up and connect to the controller and, if purchased, remote display. Connect grey
patch cords from controller terminals to KwikLink connectors installed in Step 3.

supply(ies) (consult factory); set up and connect to KwikLink connectors installed in
Step 3.
8. Set up and connect vacuum receiver stations to ArmorBlocks installed in Step 3,
using yellow patch cords.
9. Set up and connect vacuum pump stations and filter chambers to ArmorBlocks
installed in Step 3, using yellow patch cords.
10. Determine location(s) of central alarm(s); set up and connect alarms using yellow
patch cords.
The following sections provide detailed information on these installation steps.
3-4 Electrical Connections
Refer to local electrical codes, the schematic and connection diagrams supplied with this unit
and the serial tag for wiring considerations. Run all wiring in conduit if codes require it.
Making Control Panel Power Drop Wiring Connections
Hardwire the input power at 115/1/50-60 VAC or 230/1/50-60 VAC, depending on the
specifications, which are located on the Control Panel Serial Tag. The control enclosure
draws less than five (5) amps during normal operation at 115/1/50-60 VAC. The main power
switch is located on the right side of the enclosure.
Caution!
We recommend that you protect PLC memory by providing the control
panel with a dedicated circuit, a true earth ground, and a spike/surge
protector.
Running KwikLink™ Cables
About KwikLink Flat Cables
KwikLink flat cable is physically keyed to prevent wiring mishaps. This type of cable is
unshielded and contains four conductors. Use a long-jawed straight-bladed cable cutter at
least 1½” long to cut KwikLink flat cable.
You’ll install two (2) colors of flat cable: black and grey. The black cable transmits output
power, and the grey cable transmits input power and data transmission.

Installing KwikLink Cable
Before you install flat cable, determine how much length you need to install black power
cable and grey data cable. Typical installations have equal lengths of each. This is a good
time to plan for the future, and run these cables to each possible location in the plant. Use a
straight-blade cable cutter to make the cut at each end.
To install KwikLink cables:
1. Cut both black and grey cables to the proper length.
2. Use cable ties to attach KwikLink cables, black cable above grey cable, on the
vacuum tubing. Attach cable to the tubing with cable ties at about three-foot (3 ft./
1 m) invervals. Make sure that cable ties are snug, but not tightened enough to bend
the flat cable.
Caution!
Install KwikLink cable on vacuum tubing only. DO NOT install KwikLink
cable on material conveying tubing, as static electricity formed at material
lines could disrupt system operation.

Note: When approaching a node location, stop the attachment process. Run
the cables over the node area (such as a T-valve) and make sure you
create a slight amount of slack when continuing the attachment with
cable ties. Doing so lets you install KwikLink connectors or
ArmorBlocks with greater ease, with less stress on the cable.

Setting Up and Installing Mounting Plates
Setting Up Mounting Plates
It’s a good idea to get all your mounting plates set up with KwikLink connector bases or
ArmorBlock cable bases before installation, as your system layout determines.
Note: ArmorBlock cable bases are installed on mounting plates
perpendicular in orientation to the flat cable runs.
Vacuum hoppers/receiver stations require 8-connector ArmorBlocks; vacuum
pumps and central alarm stations require 4-connector ArmorBlocks.
Make sure that each mounting plate has properly attached tube clamps as required. Each
mounting plate requires two (2) tube clamps. Always use locking washers, especially in
high-vibration environments.
Figure 3: Side View of a Typical Mounting Plate Assembly with ArmorBlock Base
Rotate 30º to 45º downward
Installing Assembled Mounting Plates
After you’ve set up the mounting plates:
1. Install them at each node location by clipping the tubing clamps onto the vacuum
tube, just before the node area (such as a T-valve).
2. Orient the mounting plate parallel with the flat cables and at a 30º to 45º angle so the
KwikLink connector or ArmorBlock faces the operator on the floor; torque the tubing
clamp fasteners until tight.
The flat cable will be installed inside KwikLink connectors and ArmorBlocks as described in
the following sections of this chapter.

Terminating Cable Runs
After you’ve run the black and grey network cables, you need to properly terminate the ends
of the cables. By doing so, you’ll insure that the network runs properly. You will also have
the benefit of being able to measure voltage in the system without disrupting operation.
This section lists procedures for terminating these cables. To properly terminate a cable run:
1. Mount three standard KwikLink connectors to a mounting plate in a triangle
configuration. See Figure 4 on Page 19 for an illustration.
Make sure that each connector is installed with the hinge side down.
2. Mount the tubing clamps to the mounting plates. Each mounting plate requires two
(2) tubing clamps.
3. Mount the standard resistor cap from the KwikLink connector kit on the top center
KwikLink connector for the black power flat cable. The standard resistor cap has
metal prongs in the center.
Repeat for the outside end KwikLink connector on the grey data flat cable.
4. For the inside KwikLink connector (next to the outside end on the grey cable), mount
a separately-packaged blank cap on it instead of the standard resistor cap in the
KwikLink connector kit.
Discard the standard resistor cap to eliminate confusion.
5. Mount the mounting plate assembly on the vacuum line at the end of the cable run.
See Page 17 for more information.
6. Using the straight-blade cable cutter, carefully trim each flat cable so it sticks out past
the final KwikLink connector by 1/4” to 3/8”.
Place a dust cap over the end of the trimmed cable.
7. Lay the dust cap and cable into the KwikLink connector so the dust cap tabs engage
in the connector slots. The dust cap tabs should fit into the connector slots perfectly.

8. Lay the cable in the hinged base, noting the correct keyed profile; flat edge toward
the hinge, keyed edge toward the latch. Make sure that the cable and dust cap are
properly seated inside.
9. Making sure that the cable is completely straight, carefully close the hinged
assembly, and apply firm, even pressure until the first latch locks into place.
Note: Make sure that the flat cable is completely staight before continuing!!
The latch has two catches; the first loosely holds the connector on the cable, the
second requires more pressure to close the connector tightly. The cable must be in the
correct position for the connector to close properly.

10. Drive the two screws at the center points about halfway down; first on the latch side,
then the hinge side.
11. Continue to tighten the screws a little at a time until fully tightened; no more than 15
inch-pounds (5.6 N•m) of torque.
Note: You can only pierce the cable once. Once pierced, the KwikLock
connector must not be removed. This insures that the inner conductors
are not exposed to the elements.
Installing Inside KwikLink Connectors with Blank Caps
Once installed on the grey data cables, these connectors permit you to measure voltage in the
system so you can analyze how it is working. The system cannot work properly unless these
inside-mounted connectors have the blank (non-conductor) caps installed.
1. Lay the cable in the hinged base, noting the correct keyed profile; flat edge toward
the hinge, keyed edge toward the latch. Make sure that the cable is properly seated
inside.
2. Making sure that the cable is completely straight, carefully close the hinged
assembly, and apply firm, even pressure until the first latch locks into place.
Note: Make sure that the flat cable is completely straight before continuing!!
The latch has two catches; the first loosely holds the connector on the cable, the
second requires more pressure to close the connector tightly. The cable must be in the
correct position for the connector to close properly.
3. Drive the two screws at the center points about halfway down; first on the latch side,

Addressing and Installing ArmorBlocks™
Addressing Armorblocks
An ArmorBlock permits you to give it a number “address” so that the controller network
system can recognize its location and function. ArmorBlocks are used at vacuum
hopper/receiver, pump, and alarm node locations.
ArmorBlock Address Ranges
The number range of ArmorBlock addresses are as follows:
• 01 to 50 — Vacuum hopper/receiver stations; use a leading zero for
numbers 01 to 09.
• 51 to 57 — Pump stations
• 58 to 60 — Alarm stations
Setting Armorblock Addresses
Locate the rotary switches underneath the ArmorBlock. The two switches are:
• MSD (most significant digit) for tens
• LSD (least significant digit) for units/ones
For example, if you wanted to set an address at 36, you set the MSD rotary switch at 3 and
the LSD rotary switch at 6. To set an address of 8, set the MSD rotary switch at 0 (leading
zero), then set the LSD rotary switch at 8.
• Using a permanent black marker, write the number of the address
on the white label located on the bottom front of the ArmorBlock.
We suggest that you place numbered tags at node locations to ease
installation and reduce any confusion of locations.
To set the node address:
• Use a small straight-bladed screwdriver to rotate the switches.
Line up the small arrowhead on the switch with the number you want
to select.
The following figure shows that the address is set at 01; the MSD rotary switch is set at 0 and
the LSD rotary switch is set at 1.

Installing ArmorBlocks
The ArmorBlock cable base should already be attached to the mounting plate, aligned so it is
perpendicular to the flat cables. If not, reinstall it with its proper alignment.
To install the flat cables in the ArmorBlock cable base:
1. Lay the flat cable into the ArmorBlock cable base, grey data cable on the bottom and
the black power cable on the top, making sure that the keyed edge is properly seated
toward the top.
Caution!
EXERCISE CARE when handling the seal block.
Cable contacts are SHARP!
Only ONE attempt to pierce the cable is allowed for proper contact.
Figure 6: Using seal block to pierce cable
2. Align the seal block so the L-shaped tabs are towards the top, and the arrows are
matched on the bottom of the cable base and seal block. Make sure that the arrows
and the four captive screws on the seal block are properly aligned. Gently press it
into place.
Make sure that you align the seal block properly when you attach it to the base.
Doing so maintains the integrity of the sealed base.
Note: You can only pierce the cable once. Once pierced, the seal block must
not be removed. This insures that the inner conductors are not exposed
to the elements.

Figure 7: Securing the Seal Block to the Cable Base
To secure the seal block:
1. Start the threads of each of the four captive screws into the cable base receptacle
holes.
2. Drive each of the screws about halfway down, using the proper torque sequence:
Bottom screw, top screw, left screw, right screw. Doing so insures that the cables are
pierced evenly.
3. Using the proper torque sequence, tighten each screw, a little at a time, until the
seal block is fully seated into the cable base. Tighten to no more than 8 to 10 inch-
pounds (3.0 to 3.7 N•m) of torque.
The three seat lines on the seal block should meet the cable base, indicating that the
seal block is fully seated. The seal block clips should also click into place onto the
corresponding cable base slots.

Installing KwikLink™ Connectors
KwikLink connectors let you connect the controller and the power supply to the system. They
are also used to electronically terminate power cable and data cable runs.
Just like ArmorBlocks, KwikLink connectors are insulation displacement connectors (IDCs).
Caution!
Exercise care when installing Kwiklink connectors.
IDC blades on KwikLink connectors are SHARP!
Gently push back any protruding IDC blades before installing flat cables
inside.
The KwikLink connector should already be attached to the mounting plate, so the hinge side
is down. If not, reinstall it with its proper alignment, along the correct flat cable. See the
installation drawing located in your Customer Information Packet for further details.
To install flat cable inside KwikLink connectors:
1. Lay the cable in the hinged base, noting the correct keyed profile; flat edge toward
the hinge, keyed edge toward the latch. Make sure that the cable is properly seated
inside.
2. Making sure that the cable is completely straight, carefully close the hinged
assembly, and apply firm, even pressure until the first latch locks into place.
Note: Make sure that the flat cable is completely straight before continuing!
The latch has two catches; the first loosely holds the connector on the cable, the
second requires more pressure to close the connector tightly. The cable must be in the
correct position for the connector to close properly.
3. Drive the two screws at the center points about halfway down; first on the latch side,
then the hinge side.
4. Continue to tighten the screws a little at a time until fully tightened; no more than 15
inch-pounds (5.6 N•m) of torque.
Note: You can only pierce the cable once. Once pierced, the KwikLink
connector must not be removed. This insures that the inner conductors
are not exposed to the elements.

Connecting the Power Supply Enclosure to the Network
The power supply provides electrical power to make the system work. Some network layouts
require more than one power supply.
Location is also an important consideration when locating power supply enclosures on your
network. Contact the factory for determining how many power supply enclosures your system
needs, as well as where they need to be installed.
After you’ve mounted the power supply enclosure(s), you can connect them to your network.
To connect a power supply to the network:
1. Attach a KwikLink connector included in the bag with power cables to the flat
cables. One connector is used for the network grey cable and one connector is used
for the auxiliary power black cable.
2. Align the square connector of the grey drop cable so the cable leads down from the
connector. Evenly press the square connector onto the top of the bottom KwikLink
connector. It should make two audible snaps when properly seated.
3. Align the square connector of the black drop cable so the cable leads down from the
connector. Evenly press the square connector onto the top of the upper KwikLink
connector. It should make two separate, audible snaps when properly seated.
4. Attach the keyed round connectors to the receptacles on the side of the power supply
enclosure marked 24 VDC POWER SUPPLY. Tighten the cord grip ring until
snug.
5. Dress the excess cables with cable ties so they do not interfere with operation and to
give a pleasing appearance.
If more than one power supply is required to properly energize the grey network flat cable:
1. Remove the terminal block jumpers on all but the most centrally-located network
power supply enclosures.
For locations of jumpers, refer to the drawing shipped inside the power supply
enclosure
Note: Only one power supply should be connected to each section of the
black auxiliary power flat cable. Do not remove any jumpers on power
supplies that transmit energy to the black flat power cable.

Checking Addressing and Wiring for System Components
Once you have set the number of stations and pumps as described previously, you should
verify that the controller is communicating with all stations, pumps, and central alarms, and
with the ArmorBlocks for all central purge valves. To do so:
1. At the System Setup screen, touch DeviceNet Node Statusnear the lower
right of the screen.
The DeviceNet Node Status screen appears:
2. Check that the expected components are shown as present (green) and not present
(black). (Disregard any error messages.)
For example, if you have 18 stations, boxes 01through 18in the Stationssection
should be green and boxes 19through 50should be black. For central purge valves,
you should see a green box for each ArmorBlock installed.
If the screen display is not as expected, either a component’s ArmorBlock has an incorrect
address or the ArmorBlock is not correctly wired to the network.
When you have verified that the controller is communicating with the other system
components, you should verify that the inputs on all ArmorBlocks for stations and pumps are
wired correctly and are working correctly. To do so:
1. At the DeviceNet Node Status screen, touch DeviceNet Input Statusnear
the lower right of the screen.

The DeviceNet Input Status screen appears:
Station numbers are stacked vertically as column headings in this screen.
2. Check that all inputs are on (green) or off (black) as expected and that they switch on
and off as required:
a. Station demand switch: In a new installation, the box labeled Demand
Switchshould be green for every station (vacuum hopper) in the system.
(All other boxes for demand switches will be black.) In a retrofit at an
existing installation, each station’s Demand Switchbox should be green
unless the receiver bin under the station is in fact full.
b. Station volume-fill proximity switch: For each time-fill station, the box
labeled Volume Fill Proxshould be black; no further check is needed
for these stations. For each volume-fill station, you should calibrate the
sensor now and, at the same time, check this input. To calibrate the sensor,
remove the station’s cover, extract the volume-fill proximity switch, and
place the switch in a container of the material that you will be using at this
station. Adjust the sensor according to the procedure given in the
manufacturer’s documentation for the switch. While you are doing this,
check that:
1.
The box on this screen is green when the sensor indicates that no
material is present, and
2.
The box is black when the sensor indicates that material is
present.
Then reinstall the switch in the station.

c. Station bypass switch: For every station, the box labeled Bypass Switch
should match the state of the switch at the station. Flip the switches at the
stations in order to check that:
1.
Each station’s box is black when its bypass switch is in the “0”
position (station ready to convey), and
2.
Each station’s box is green when its bypass switch is in the “1”
position (station bypassed).
Leave each station with its bypass switch off (in the “0” position).
d. Station receiver level: For each station whose receiver has no low-level
switch, the box labeled Receiver Levelshould be black; no further
check is needed for these stations. For each station whose receiver has a low-
level switch, you should calibrate the sensor now and, at the same time,
check this input. To calibrate the sensor, remove the receiver’s cover, extract
the low-level switch, and place the switch in a container of the material that
you will be using at this station. Adjust the sensor according to the procedure
given in the manufacturer’s documentation for the switch. While you are
doing this, check that:
1.
The box on this screen is green when the sensor indicates that no
material is present, and
2.
The box is black when the sensor indicates that material is
present.
Note: You will not see any alarms for “receiver low level” during this
procedure. In order to prevent nuisance alarms when the system starts,
the controller’s software is designed to issue these alarms only after
material has been detected in the receiver at least once.
When you have finished calibration and checking, reinstall the switch in the
receiver.
e. Pump inputs (verify, high vacuum, fault #1, fault #2): All boxes for pump
inputs should be black. Because these inputs can turn on only when the pump
is running, it is not possible to check their operation further at this point.
If any input does not operate as expected, check the wiring on the ArmorBlock. If this does
not solve the problem, phone the Service Department for assistance.

Setting Up Pump Staging
To avoid an excessive power demand at your facility when the conveying system starts up,
you can stagger the times at which pumps start. Whenever a demand would cause two pumps
to start simultaneously, your choice for pump staging sets the delay between the start of one
pump and the start of the next. The factory default is a delay of three seconds. You need to
change this setting only if this delay is too long or too short for your facility.
To set the delay between the start of one pump and the next:
1. Go to the System Setup screen if needed.
To reach this screen from the Station Summary or Pump Summary screen, touch and
hold the icon for any station or pump, until the Station n Operator or Pump n Setup
screen appears. Then touch System. The System Setup screen appears.
The current delay is displayed under Pump Staging.
2. Touch Pump Staging.
A keypad pops up, with an entry of 0.
3. Enter the number of seconds (range: 1–99). Use ← to erase any mistakes. Use ↵ to
enter the value.
The keypad disappears and the new setting appears under Pump Staging.
Setting Up Touch Switch Delay
During operation, the controller normally displays the Station Summary screen or the Pump
Summary screen, showing the current status of all stations or pumps. Briefly touching the
icon for a station or pump toggles between taking it offline (disabling it) and putting it online
(enabling it). Touching the icon and holding it takes the user into the controller’s menu
system. The setting for touch switch delay determines how long the user must keep an icon
touched before a menu appears. The factory default is 1.5 seconds. You need to change this
setting only if you find that users are having difficulty with the current setting.
To change the touch switch delay:
1. Go to the System Setup screen if needed.
To reach this screen from the Station Summary or Pump Summary screen, touch and
hold the icon for any station or pump, until the Station n Operator or Pump n Setup
screen appears. Then touch System. The System Setup screen appears.
The current delay is displayed under Touch Switch Delay.
2. Touch Touch Switch Delay.
A keypad pops up, with an entry of 0.
3. Enter the number of seconds (range: 0.0–99.0). As with many ATM machines, the
first digit you enter initially appears to the right of the decimal point and moves to the
left as you enter more digits. You do not need to use the decimal point. Use ← to
erase any mistakes. Use ↵ to enter the value.
The keypad disappears and the new setting appears under Touch Switch Delay.

Finishing Setup: Setting Up Passwords
You can set up passwords for two levels of security: for operators and for setup personnel.
The controller comes from the factory with neither password set. This allows every user
access to all functions.
Setup Password. If you define a password for setup personnel, then most settings can be
changed only after entering the password. The password will be required to display the
following screens:
• System Setup (to review and change system-wide settings, clear the
alarm log, and go to the network status screens)
• Station Setup (to review and change settings for all station options)
• Pump Setup (to review and change settings for all pump options)
Operator Password. If you define a password for operators, then a password will be
required to carry out any function (other than reviewing station and pump status, silencing
alarms, reviewing the alarm log, and looking at help screens). Entering the operator’s
password will give the user access to the functions at the following screens:
• Station Summary (to enable or disable a station, and start or stop
system)
• Pump Summary (to enable or disable a pump, and start or stop system)
• Station n Operator (to adjust a station’s convey time and dump delay,
activate priority convey, and review the station’s last convey time and
pump assignment; depending on the options installed, the screen may
also enable the operator to adjust the mixture percentage for a remote
proportioning valve, review the last purge time and purge valve, and
set the intended material line for material proofing)
Entering the setup password will give the user access to all functions.
Note: If you want to protect the operator’s functions with a password, you
must also define a setup password. If you leave the setup password
undefined, then all users will have access to all functions.
If you want two different levels of password protection, you must make the
passwords different from each other. If the two passwords are the same as each
other, then any user who enters the password will have access to all functions.
To set (or remove) password protections:
1. Go to the System Setup screen if needed.
To reach this screen from the Station Summary or Pump Summary screen, touch and
hold the icon for any station or pump, until the Station n Operator or Pump n Setup
screen appears. Then touch System.

Password. A value of 0000means that no password is required.
2. Touch Operator Password or Setup Password, as appropriate.
A keypad pops up, with an entry of 0.
3. Enter up to four digits. If you want to remove the password protection, simply leave
the entry at 0. Use ← to erase any mistakes. Use ↵ to enter the value.
The keypad disappears and the new setting appears under Operator (or Setup)
Password. In addition, if you have added a password, a new button appears on the
screen, labeled Log Off Operatorand/or …Setup, depending which
passwords are now active.
Note: When entering a password, all four digits must be supplied. For
example, if you enter a password of 2here, you will need to enter
0002when the controller prompts for the password.
If desired, you can also change the duration for which a password remains effective. During
operation, the password-protected screens are available either until the user logs off or until
this time elapses, whichever comes first. This feature prevents the password from remaining
active if a user forgets to log off.
Note: The password timer starts when the user logs on. It expires even if the
user is actively using the screens when the chosen time is up. If the
timer expires, the system goes to the Station Summary screen. Your
password duration should be long enough to allow authorized users to
complete their tasks but short enough to provide adequate protection
against tampering.

Chapter 4: Operation
4-1 Overview
Your 7/50D Plus or 7/50D controller electrically controls valves and solenoids to convey
material from a central location to individual stations as needed. The controller senses
demands for material at the stations and responds to the demands in a timely fashion.
This section gives the procedures for using your controller, and it covers tasks that can be
carried out with no password or with an operator’s password. The section is divided into four
sub-sections:
• Starting and stopping the system
• Basic tasks: tasks normally carried out by a station operator
• Advanced tasks: tasks normally carried out by setup personnel
• Alarms: silencing and clearing alarms
Note: Before you carry out any of the procedures in this chapter, the system
must be set up as described in the previous chapter.
4-2 Starting and Stopping the System
Note: In an emergency, you can use the power switch on the upper right-
hand side of the controller cabinet if a password is required to stop the
system and you do not know the password.
Normally, all the stations and pumps you want to use should be enabled before
you start the system. When the system is stopped, icons for enabled stations are
blue when full and yellow when they need material. Icons for enabled pumps
are yellow. Enabling stations and pumps is described on p. 60.
A button to start and stop the system is located in the lower right of the Station Summary,
Pump Summary, and Alarm Log screens. When the system is off, the button is red and reads
Push to Start System. When the system is on, the button is green and reads Push
to Stop System. Depending on the setup at your facility, the system may prompt for a
password when you touch this button.
Note: If conveying does not begin when you start the system, check to make
sure that all needed pumps are enabled. If they are, check that all
needed stations are enabled.

Logging On and Logging Off
Your controller may be set up to require a password for any operation (other than reviewing
station and pump status, silencing alarms, reviewing the alarm log, and looking at help
screens). If so, a keypad appears when you touch a button for a screen that requires a
password:
• Enter the four-digit password (including any leading zeros). For
example, if the password is 1, enter 0001.
Each digit appears as an “X” as you touch it. When you touch the fourth digit, the
controller carries out your request. For example, it enables or disables the requested
pump or station, or it goes to the Station n Operator screen. If you did not enter the
correct password, the controller erases the entry. You can then try again. To give up,
touch Return.
Note: If you have lost the password(s), contact the manufacturer for
assistance.
Once you have logged on, the password remains active until you log off or the password
expires. (Setup personnel at your facility control the number of minutes before the password
expires.) While the password is active, you can continue to carry out password-protected
tasks without reentering the password. If the timer expires, the controller goes to the Station
Summary screen and you must reenter the password to continue working.
When you have finished any tasks that require the password, you should log off. (If you
forget to do this, the controller will log you off when the password expires.) To log off:
1. Go to a Station Operator screen.
To reach this screen, go to the Station Summary if needed by touching Stationsat
any screen. Then touch and hold the icon for any station until its Station Operator
screen appears.
2. Touch Log Off Operatornear the lower right of the screen.
The Station Summary screen appears.

Enabling and Disabling Stations and Pumps
When a station or pump is disabled, the controller makes no attempt to use it and ignores any
alarms that occur for it. Disabling a station or pump at the controller’s screen is similar to
bypassing a station with its bypass switch. Enabling a station or pump makes it available for
use. (For a station to be available for the system, it must be enabled at the controller’s screen
and its bypass switch must be in the “0” position.)
To enable or disable a station (or pump):
1. Go to the Station Summary (or Pump Summary) screen, if needed.
To reach this screen from any other screen, touch Stations(or Pumps) on the
right-hand side of the screen.
Each disabled station (or pump) has an icon with a status of “offline” (black with a
gray outline). All other statuses are enabled statuses.
2. Touch the icon for the station (or pump) briefly.
The station (or pump) switches to the new state, as indicated by the color of its icon.
Note: If the Station n Operator (or Pump n Setup) screen appears when you
touch the icon, then you have kept your finger on the screen too long.
Touch Stations(or Pumps) to return to the Summary screen and
try again. If you find it difficult to touch the icon briefly enough, ask
the setup personnel at your facility to lengthen the touch switch delay.

Navigating among the Station Operator Screens
The controls in the upper right-hand corner of the screen enable you to move among the
Station Operator screens:
1. To display the screen for the next lower-numbered station (for example, to move
from the screen for Station 15 to the screen for Station 14), touch ◄ Back.
2. To display the screen for the next higher-numbered station (for example, to move
from the screen for Station 15 to the screen for Station 16), touch Next►.
3. To display the screen for a specific station, touch Goto. A keypad pops up. Enter the
number for the desired station. Use ← to erase any mistakes. Use ↵ to enter the
value.
4. To exit to the Station Summary (or Pump Summary) screen, touch Stations(or
Pumps).
Adjusting Convey Time and Dump Delay
Convey time is the length of time the station’s vacuum valve remains open to allow material
to be drawn in. (For a volume-fill station, the valve closes when material covers the station’s
volume-fill proximity sensor or this time elapses, whichever comes first.)
Dump delay is the length of time allowed for material to drain from the station into its
receiver. During this time, the controller does not attempt to deliver any more material to the
station.
The settings for convey time and dump delay should match the times actually required to fill
and empty the station. The following problems may occur if these settings are incorrect:
1. Material is backing up and causing “high vacuum” alarms (for time-fill stations
only): Convey time is too long.
2. System is not keeping up with the demand for material: Convey time is too short, or
dump delay is too long.
For your reference, the Station n Operator screen shows the length of time the controller
actually spent conveying material during the most recent delivery under Last Convey
Time.
To adjust a station’s convey time (or the dump delay):
1. Go to the Station n Operator screen (as described on p. 61), or go to the Station n
Setup screen.
2. Touch Convey Time (or Dump Delay).
A keypad pops up.
3. Enter the number of seconds desired. Use ← to erase any mistakes. Use ↵ to enter the
value.
The new setting appears under Convey Time(or Dump Delay).
Note: If you change convey time by more than a few seconds for a station
with a remote proportioning valve (RPV), notify the setup personnel at
your facility. The setting for the RPV’s cycle time should be adjusted to
divide evenly into the new convey time (see pp. 43 and 77).

Activating and Stopping Priority Convey for a Station
Note: Before activating priority convey, make sure that all other stations
using the same pump have adequate material in reserve to continue
operation. No material will be conveyed to these stations during
priority convey.
If you want the controller to fill a specific station with material immediately, you can activate
“priority convey” for that station. When you do so, the controller temporarily dedicates the
station’s pump to it, ignoring demands from other stations assigned to that pump. Once the
chosen station is full, normal operation resumes.
You can also use this feature to give one station a “head start” by conveying a few loads to it
and then stopping the priority convey.
No more than one station for a given pump can be in “priority convey” at once.
To activate priority convey:
1. Go to the Station n Operator screen (as described on p. 61), or go to the Station n
Setup screen.
2. Touch Priority Convey Activate.
The button changes to Priority Convey Activeand blinks until the station’s
demand has been satisfied (or you stop the priority convey).The controller begins
filling the chosen station only (after finishing any convey already in progress).
To stop a priority convey before the station is completely full:
1. Touch the blinking Priority Convey Active.
The button changes to Priority Convey Activateand stops blinking. The
controller finishes the current convey, if any, and resumes normal operation.
Changing the Mixture for a Remote Proportioning Valve
A remote proportioning valve (RPV) mixes two different materials, typically virgin and
regrind materials, during a convey cycle. If present, this valve may be set up so that you
control the mix with a timer at the station, or it may be set up so that you control the mix with
the controller’s touch screen. The instructions here apply only for controlling the mixture
from the touch screen.
The controller refers to the two materials as Material A (primary) and Material B (additive).
The system is set up so that, if there are any inaccuracies in the proportions, the mix will
contain more Material A and less Material B.
To change the mixture for the remote proportioning valve:
1. Go to the Station n Operator screen (as described on p. 61), or go to the Station n
Setup screen.
2. Touch RPV Material B.
A keypad pops up.
3. Enter the desired percentage for the additive material. Use ← to erase any mistakes.
Use ↵ to enter the value.
The new setting appears under RPV Material B.

Transferring Stations to a Standby Pump
If a pump fails, you can transfer all of the controller’s station assignments for that pump to a
standby pump. To do this, you must disable (take offline) both the source pump and the
standby pump, and the standby pump must have no stations already assigned to it.
The transfer operation at the controller’s touch screen merely changes the pump assignment
for every station on the failed pump. It does not transfer any pumps settings for auto
shutdown delay, alarms, or blow-back to the standby pump. Mechanical connections must be
changed manually.
To transfer stations from a pump to a standby pump:
1. At any screen, touch Pumps.
The Pump Summary screen appears.
2. Both the source pump and the standby pump must be offline. If either pump is any
other state, disable it by touching its icon briefly.

Silencing Alarms
Whenever a new alarm occurs, your controller sounds the horn and turns on the strobe light at
each central alarm. If the alarm is for a specific station or pump, and if the station or pump
has a local alarm, the controller also turns on the local alarm light. In addition, the
manufacturers’ logo on the controller’s screen changes to an Alarm Silencebutton.
To silence the alarm:
1. Touch Alarm Silencein the lower right-hand corner of the screen.
The horns and lights at the central alarms turn off. (The local alarm light stays on.)
The button changes back to the company logo. Your controller has separate,
configurable settings for how long the horns should remain silent and how long the
lights should remain off. If the alarm condition still exists when either of these times
elapses, the corresponding devices (horns or lights) turn on again. If a new alarm
occurs, both the horns and the lights turn on.

Network Scanner Module Considerations
The manufacturer includes a network scanner software diskette with your controller; this
diskette and instructions are located in your Customer Information Packet. Keep this diskette
and the instructions in a safe place.
Should the network scanner module require replacement, use the scanner software to restore
the program. You can:
• Purchase a programmed replacement scanner module from the
manufacturer
• In extreme cases, you can purchase the module from your local Allen-
Bradley dealer and program it yourself with the scanner software
diskette; you can also have your A-B dealer do that for you
We suggests that you have a preprogrammed spare network scanner module on hand for such
conditions.

Chapter 6: Configurable Settings
This section describes the proper setup of the 7/50D Plus or 7/50D control system parameters.
These parameters are operator changeable; however, these items should require setup only
during the initial installation. Only authorized personnel should change them.
Many of the variables and setup parameters have been preset at the factory and do not need to
be changed. However, this section of the manual will address all of the setup parameters that
were available at the time of printing. The purpose of this is to familiarize the reader with all
the setup parameters and their usage.
6-1 Memory Module Considerations
The operator interface and the PLC central processing unit use memory modules to store the
operating program. The modules are installed in the back of the controller interface chassis
and on the PLC CPU card.
The memory module returns the controller to the factory default settings if an electrical fault
occurs, or if the hardware is replaced. Keep in mind that this condition is extremely rare.
You will then need to set up the controller once again with the settings you programmed in
this chapter.
