1-3 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.
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 2-Pump, 20-Station Controller. Failure to do so may
result in serious injury. No one but the person who installed the lockout may remove
it.

1-4 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.
Hold daily equipment inspections in addition to regular maintenance checks. You will keep
your equipment safe for production and exhibit your commitment to safety.
Please read and use this manual as a guide to equipment safety. This manual contains safety
warnings throughout, specific to each function and point of operation.
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.

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 Menu button on any screen. Then
touch System Setup. The “System Setup” screen will pop up.
2. Touch the Pump Staging button. A keypad pops up.

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 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 mix
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. 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 Menu button on any screen. Then
touch System Setup. The “System Setup” screen will open.
2. On the “System Setup” screen (Figure 4), touch the Operator Password button or
the Setup Password button, depending on which password you want to set up. A
keypad pops up.
3. Enter up to four digits. If you want to remove password protection, enter 0 as the
password. Use
(Backspace Key) to erase any mistakes. Use
(Enter
Key) 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.
To change the duration of the password, complete the following steps:
1. On the “System Setup” screen (Figure 4), touch the Operator Password Duration
button or 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
(Backspace Key) to erase any mistakes. Use

Chapter 4: Operation
4-1 Overview
Your 2-pump, 20-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 Menu on the right-hand side of the screen, and then touch Stations.

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 15: “Password Entry” Screen
2–Pump 20-Station Controllers
Operation
29 of 51
Download from Www.Somanuals.com. All Manuals Search And Download.
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 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 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
Status” 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,
complete the following steps:
1. Go to the “Menu” screen by touching Menu from any other screen.
2. Touch Log Off Password. The “Station Status” screen opens.
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 “0” 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 Menu and then Stations (or Pumps).
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 Operator” (or “Pump 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 “Status” 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.

Starting and Stopping the System
WARNING! In an emergency, you can use the power switch at 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 blue and
icons for enabled pumps are yellow. Enabling stations and pumps is described on
p. 303.
A button to start and stop the system is located in the lower right of the “Station Status” and
“Pump Status” 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.
Reviewing and Adjusting Basic Station Settings
The 2-pump, 20-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 Menu, and then touch Stations.
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 16: “Station Operator” Screen
Settings in the box labeled Convey, the red Priority Convey Activate button, and the
menu controls on the right-hand side of the screen appear for all stations. Buttons in light
gray are settings that you can adjust at this screen. Boxes in dark gray are for display only. If
a pump assignment needs to be changed, this must be done at the “Station Setup” screen.

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:
• 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.
• 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 display the screen for a specific station, touch Goto. A keypad pops up. Enter the
number for the desired station. Use
(Backspace Key) to erase any mistakes. Use
(Enter Key) to enter the value.
• To exit to the “Station Status” (or “Pump Status”) 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 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
Time.
To adjust a station’s convey time (or the dump delay), 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 (or Dump Delay) A keypad pops up.
3. Enter the number of seconds desired for convey time or dump delay. Use
(Backspace Key) to erase any mistakes. Use
(Enter Key) to enter the value.
The new setting appears under Convey Time (or Dump Delay).

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
and 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
conveying already in progress).
3. To stop a priority convey before the station is completely full, touch the blinking
Priority Convey Active button. The button changes to Priority Convey Activate
and stops blinking. The controller finishes the current convey, if any, and resumes
normal operation.
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.32 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 Menu, and then touch Pumps. The “Pump Status” screen
opens.
2. Touch and hold the icon for the pump. The “Pump Setup” screen opens.

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. At any screen, touch Menu, and then touch Pumps. The “Pump Status” 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. The icon becomes black with a gray
outline.
3. 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.
4. At the “Pump Status” screen, touch and hold the icon for any pump until the “Pump
Setup” screen appears.
5. At the “Pump Setup” screen, touch Transfer Stations To Standby Pump. The
“Transfer to Standby Pump” screen opens:

If these conditions are not all met, error messages appear on the screen instead
of a Transfer to Standby Pump button. If you get an error message, first
check to make sure that you have entered the correct numbers and reenter if
necessary. If another error occurs, see the Standby Pump Errors section below.
10. Touch Transfer To Standby Pump. “Transfer in Progress” appears briefly on the
screen, followed by “Transfer Complete,” in place of the Transfer To Standby
Pump button. The controller switches the setting for Source Pump to the new
pump and switches the setting for Standby Pump to 0 (unassigned).
11. Touch Return, and then Pumps to return to the “Pump Status” screen.
12. Put the standby pump online by briefly touching its icon. The icon changes color to
show the new status, and the system begins using the pump. In addition, all “Station
Operator” and “Station Setup” screens show the new pump assignment.
When the failed pump is operational again, you can repeat this process, this time using the
standby pump’s number as the setting for Source Pump the repaired pump’s number as the
setting for Standby Pump.
Standby Pump Errors
If the error message tells you to disable the source pump and/or the standby pump, touch
Return at this screen, then Pumps 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 Menu.
2. From the “Menu” screen, touch Stations.
3. Touch and hold a station icon to get to the “Station Operator” screen.
4. Then touch Setup to go to the “Station Setup” screen.
5. Use ◄ Back. and Next ► to review all pump assignments.
6. Where necessary, choose Assigned to Pump #n to set station assignments to 0
(unassigned). Then return to the “Transfer to Standby Pump” screen.

Silencing Alarms
Whenever a new alarm occurs, your controller sounds the horn and turns on the strobe light at
each central alarm.
Touch Alarm Silence on the alarm message banner that appears when a new alarm occurs
or press the physical push button included in the central alarm option.
The horns and lights at the central alarms turn off. Your controller has separate, configurable
settings for how long the horns should remain silent and how long the lights should remain
off. (see “Setting U1p Alarm Duration” on page 19). If the alarm condition still exists when
either of these times elapses, the corresponding device (horn or lights) turn on again and the
alarm message banner appears with a “Suppression/Silence Time Expired” message. If a new
alarm occurs, both horns and lights turn on. See page 436 for a list of alarms and their
possible causes.

PLC Memory Module
A PLC memory module (ACS Part# A0567138) loaded with the appropriate program for the
system purchased is provided as both a backup in the event of a catastrophic failure and as a
means to upgrade the PLC program.
Depending on the system purchased, the memory module will contain:
1. A0573702
2. A0573712
VTC 2/20 AC Inputs
VTC 2/20 DC Inputs
In the event that the PLC memory becomes corrupted, the memory module can be used to
reload the PLC program with factory default values. The red FAULT indicator on the PLC
indicates a problem with the PLC memory or an error in the internal settings and may be
flashing or on steady. Follow the procedures below to reload the PLC program.
1. Open the front cover of the PLC by pulling on the tab above the words “Allen-
Bradley” to expose the memory module socket. Refer to the diagram, item 7 shown
below.

2. Insert the memory module. Note: this step can be preformed while the unit is
powered, however care should be taken not to contact any wiring within the control
cabinet.
3. Cycle power to the control cabinet allowing approximately 30 seconds for the DC
power supply (if provided) to fully discharge.
4. After approximately 30 seconds, the PLC’s green RUN indicator will flash indicating
the PLC is reading the memory module. When complete, the PLC will automatically
begin operation and the RUN indicator will be on solid.
5. Note that re-loading the memory module will restore ALL settings to their factory
default values and the settings will have to be re-entered manually.
Contact ACS service at 1-800-423-3183 if the fault persists.

Chapter 6: Configurable Settings/Defaults
This section describes the proper setup of the 2 pump, 20-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.

1–99 sec.
15 sec.
Adjust this value to match the actual time needed
to drain the station. If it is set too short, the
controller may attempt to refill the station before it
is empty, causing material to back up and/or
underusing the station’s capacity. If it is set too
long, the system may be unable to keep up with
your equipment’s demand for material.

When this option is enabled, the station’s vacuum
valve remains open for the convey time, even if
the station is not demanding material and is
indicating that it is full. When disabled, the
station’s vacuum valve opens when there is
demand from the station, and it remains open until
the convey time has elapsed or material trips the
volume-fill proximity switch.

disabled
Usually this option should be enabled. At times,
you may wish to disable it during operation as a
stopgap measure for dealing with an alarm.
Number of attempts before alarm: the number of
times the controller will attempt to convey material
to a station before it issues a “no convey” alarm.
The setting for this option depends on (a) how
much material your injection mold uses to make
each part compared with the capacity of the
receiver and (b) how important it is to keep your
injection mold from running out of material and
shutting down. A higher setting will give you fewer
alarms, at the risk of emptying the receiver without
warning. A lower setting will give more frequent
alarms, at the risk of disrupting operations
unnecessarily.
