1-3 Responsibility
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.

This manual provides operation, installation, and maintenance instructions for 4-Pump, 38-
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 4-Pump, 38-Station Conveying Controller is a programmable logic controller, with 24
VDC 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 Vacuum Pump Product manual (Part No.
A0571050) for installation recommendations.

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 conveying
system; 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.
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.

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, complete the following steps:
1. Go to the “System Setup” screen by touching the SYSTEM SETUP button on any
screen.
2. Touch the PUMP STAGING button. A keypad pops up.
3. Enter the number of seconds (between 0 and 99) for the length of the delay between the
start of one pump and the next. Use CLR to erase any mistakes. Use ENT to enter the
value. The keypad disappears, and the new setting appears under PUMP STAGING.
Setting Up Stations
Before starting the system, you must define several settings for each station, such as which
pump conveys material to it. This section first discusses how to use the controller’s menu
system to configure stations. The table on pages 36–37 discusses the individual choices. To
set up each station, perform the following:
1. Go to the “Station Status” screen if needed. To reach this screen press station status
button on any screen.

Setting Up Pumps
Before starting the system, you must define several settings for each pump, such as how
quickly to shut it down when it is not in use. This section first discusses how to use the
controller’s menu system to configure pumps. The table on page 37 discusses the individual
choices. In order to setup up the pumps properly, perform the following:
1. Go to the “Pump Status“ screen if needed. To reach this screen from any other screen,
touch PUMP STATUS button. The “Pump Status” screen appears:
Figure 7: “Pump Status” Screen
2. Touch the icon for the pump you want to set up, and hold it for several seconds. The
“Pump Setup” screen opens.

3. Adjust settings as required. Touching any box that appears in red (for “disabled”)
toggles it to green (for “enabled”), and vice versa. Touching any box that appears in
white gives you a keypad to enter a new value.
Keypad entry works as with many ATM machines: the first digit you enter initially
appears in the rightmost column and moves to the left as you enter more digits. You do
not need to use the decimal point. Use CLR to erase any mistakes. Use ENT to enter
the value. The keypad disappears and the “Pump Setup” screen shows the new value in
the selected white box.
See page 37 for details on the options and their default settings.
4. As appropriate, setup the rest of the pumps using the following method:
• Use the PREVIOUS or NEXT buttons to navigate to other pumps. Touch
PREVIOUS to go to the previous “Pump Setup” screen, or touch NEXT to go to
the next “Pump Setup” screen.
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 all 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).
• 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 Status (to enable or disable a station, and start or stop system)
• Pump Status (to enable or disable a pump, and start or stop system)
• Station 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 purge time.
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. Then any user who
enters the password will have access to all functions.
To set (or remove) password protections, complete the following steps:
1. Go to the “System Setup” screen by touching the SYSTEM button on any screen.
2. On the “System Setup” screen, touch the Operator Password button or the Setup
Password button, depending on which password you want to set up. A keypad pops
up, with an entry of 0.
3. Enter up to four digits. If you want to remove password protection, enter 0 as the
password. Use CLR to erase any mistakes. Use ENT to enter the value. The keypad
disappears, and the “System Setup” screen shows the password you entered.
Note: When entering a password, all four digits must be supplied. For example, if you enter
a password of 2 here, you will need to enter 0002 when 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 Status” 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.

the Setup Password Duration button, depending on which password duration you
want to change. A keypad pops up.
2. Enter the number of minutes (between 1 and 99) that you want to set as the password
duration. Use CLR to erase any mistakes. Use ENT to enter the value. The keypad
disappears, and the “System Setup” screen shows the new setting.
3-5 Initial Startup
Once you have finished all the setup described above, you are ready to start the system. To
start your system, complete the following steps.
1. At any screen, touch STATION STATUS or PUMP STATUS on the bottom left
side of the station status or pump status screen.
2. For each station that you want to use, briefly touch its icon. The icon turns green,
indicating that the station is full, or the icon turns yellow, indicating that the station
needs material.
3. Touch PUMPS STATUS. The “Pump Status “screen opens (Figure 7)
4. For each pump that you want to use, briefly touch its icon. The icon turns green,
indicating that the pump is ready.
5. Touch START SYSTEM in the lower left-hand corner of the screen.

Chapter 4: Operation
4-1 Overview
Your 4-pump, 38-station 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 three
sub-sections:
• 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 Basic Tasks
Reviewing Station Status
The starting point for all operations is the “Station Status” screen. To reach this screen from
any other screen, touch STATION STATUS on any screen. The “Station Status” screen
appears.

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, touching a button will open the “Password Entry” keypad screen.
Figure 11: “Password Entry” Screen
Enter the four-digit password (including any leading zeros). For example, if the password is
1, enter 0001.
Each digit appears as an “ ” 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 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 us for assistance.
Once you have logged on, the password remains active until 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 Status” screen
and you must reenter the password to continue working.

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.
Note: 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 “Convey” position.
To enable or disable a station (or pump), complete the following steps:
1. Go to the “Station Status” (or “Pump Status”) screen, if needed. To reach this screen
from any other screen, touch STATION STATUS or PUMP STATUS button.
Each disabled station (or pump) has an icon with a status of “offline” (black with a
white 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 Operator” (or “Pump Setup”) screen appears when you touch the
icon, then you have kept your finger on the screen too long. Touch STATION
STATUS (or PUMP STATUS) to return to the “Status” screen and try again.
Starting and Stopping the System
WARNING! In an emergency, you can use the power switch on the front of the controller cabinet if
a password is required to stop the system and you do not know the password.
Note: 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 green or
yellow and icons for enabled pumps are green. Enabling stations and pumps is
described on p. 27.
A button to start and stop the system is located in the lower left of the “Station Status” and
“Pump Status” screens. When the system is off, the button is red and reads START
SYSTEM. When the system is on, the button is green and reads 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.

Reviewing and Adjusting Basic Station Settings
The 4-pump, 38-station controller has a “Station Operator” screen for each station, as shown
below. This screen enables you to review and adjust all basic settings for the station.
To reach the “Station Operator” screen, complete the following steps:
1.
Go to the “Station Status” screen, if needed. To reach this screen from any other
screen, touch STATION STATUS button.
2.
Touch and hold the icon for the station, until the controller either prompts for the
password or displays the “Station Operator” screen. Once you have entered the
password (if needed), the “Station Operator” screen appears.
Figure 12: “Station Operator” Screen
Buttons in white are settings that you can adjust at this screen. Boxes in black are for display
only. If a pump assignment or purge time can be changed from operator screen, this must be
done at the “Station Setup” screen.

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.)
Unload time 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 unload time should match the times actually required to fill
and empty the station. The following problems may occur if these settings are incorrect:
•
Material is backing up and causing “high vacuum” alarms (for time-fill stations only):
Convey time is too long.
•
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 Operator” screen shows the length of time the controller
actually spent conveying material during the most recent delivery under Last Convey.
To adjust a station’s convey time (or the unload time), complete the following steps:
1. Go to the “Station Operator” screen by touching and holding a station icon, or go to the
“Station Setup” screen.
2. Touch CONVEY TIME. A keypad pops up.
3. Enter the number of seconds desired for convey time or unload time. Use CLR to erase
any mistakes. Use ENT to enter the value. The new setting appears under CONVEY
TIME (or UNLOAD TIME).

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, complete the following steps:
1. Go to the “Station Operator” by touching and holding a station icon, or go to the
“Station Setup” screen.
2. Touch PRIORITY CONVEY ACTIVATE. The button changes to PRIORITY
CONVEY ACTIVE 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 conveying already in progress).
3. To stop a priority convey before the station is completely full, Touch the PRIORITY
CONVEY ACTIVE button. The button changes to PRIORITY CONVEY
ACTIVATE. The controller finishes the current convey, if any, and resumes normal
operation.
Navigating among the “Station Operator” Screens
The controls at the top of the screen enable you to move among the “Station Operator”
screens:
•
•
•
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 PREVIOUS.
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.
To exit to the “Station Status” (or “Pump Status”) screen, touch STATION STATUS
(or PUMP STATUS).

4-3 Adjusting Advanced Settings
This section describes the procedures carried out during operation that are normally reserved
for setup personnel. These procedures require use of the setup password (if your facility has
defined one). The procedure for logging on and off with the setup password is the same as for
logging on with the operator password; see p. 26 for step-by-step instructions for logging on
and off.
Reviewing and Resetting a Pump Hour Meter
The controller keeps two meters for the length of time a pump has run. One, like a car’s
odometer, keeps a running total and cannot be reset. The other, like a car’s trip odometer,
counts the running time since the last reset.
To review and reset the hour meter, complete the following steps:
1. At any screen, touch the PUMP STATUS button.
2. Touch and hold the icon for the pump. The “Pump Setup” screen opens.
Figure 13: Pump Setup Screen
The box labeled x Hours shows the running time since the last reset. The box labeled total x
Hours shows total running time.
To reset the resettable meter, touch Hour Meter Reset. The time above x Hours changes to
0.

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 pump 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, complete the following steps:
1.
2.
At any screen, touch PUMP STATUS button. The “Pump Status” screen appears.
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. The icon becomes black with a
white outline.
3.
4.
5.
Move the vacuum hose from the failed pump to the standby pump, and carry out any
other mechanical procedures needed to use the standby pump.
At the “Pump Status” screen, touch and hold the icon for any pump until the “Pump
Setup” screen appears.
At the “Pump Setup” screen, touch Transfer Stations To Standby Pump. The
“Transfer to Standby Pump” screen opens:

If the error message tells you to disable the source pump and/or the standby pump, touch
RETURN at this screen, then PUMP STATUS at the “Pump Setup” screen. Take the pumps
offline and then return to the “Transfer to Standby Pump” screen.
If the error message tells you that the standby pump has stations assigned, you must either use
a different standby pump or you must remove the pump assignment for all stations assigned
to the standby pump. To remove the assignments, complete the following steps:
1. Touch RETURN at the “Standby Pump” screen, and then touch STATION STATUS.
2. Touch and hold a station icon to get to the “Station Operator” screen.
3. Then touch STATION SETUP to go to the “Station Setup” screen.

This section describes the proper setup of the 4 pump, 38-station 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.
