2–Pump 12-Station Controllers Chapter 1: Safety 7
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.
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.
2–Pump 12-Station Controllers Chapter 1: Safety 8
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 2-Pump, 12Station 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 2-Pump, 12-Station Conveying Controller is a programmable logic controller, with 24
VDC or 115 VAC control circuit, easy-to-use 16-key operator interface keypad and optional
audible/visual alarm.
2-2 General Description
Our systems create vacuum for the automatic pneumatic conveying of most free-flowing, dry,
pelletized, or granular materials in a central material handling system. 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.
Note: Vacuum leaks occuring anywhere in your system reduce capacity.
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.
Time-fill Capability. The length of time a station’s vacuum valve remains open to allow
material to be drawn into its receiver.
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.
Pump 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.

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, 12-Station Controller. Failure to do so may
result in serious injury. No one but the person who installed the lockout may remove
it.
2-Pump, 12-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. 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
vacuum hoppers, the filter chamber atmospheric valve (if so equipped)
and the pump motor starter(s), vacuum switch(es), and vent valve(s).
Mount the 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 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
Plug the power cord supplied with your unit into a properly grounded, 3-slot, 115/1/50-60 VAC
or 230/1/50-60 VAC receptacle specified on the control panel serial tag. The control enclosure
draws less than five (5) amps during normal operation at 115/1/50-60 VAC.
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.
Your 12-station controller system can operate from a 115 VAC or 220 VAC source at 50 Hz
or 60 Hz. The main power switch on the controller is located on the right side of the housing.
Built into the power switch are the controller fuses. Also, the configuration of the fuse holder
determines the voltage setting of the controller (115/220 VAC).
Marked on the faceplate of the fuse holder shows the configuration for the desired voltage.
Using a small screwdriver, remove the fuse holder. To select the operating voltage, align the
arrow marker on the holder and the switch as shown in the following section.
The 12 station controller has a standard IEC power cord. Plug the cord into any standard 115
VAC outlet. If you selected the 220 VAC option, remove the end connector and install a
standard 220 VAC plug. Doing so does NOT effect the controllers warranty.
DC Controller Power Sources
Although main controller power is 115/220 VAC, control power is actually unregulated 24
VDC. The 24 VDC control power supplies the power for all solenoids, sensors, and the
controller itself. The unregulated supply can deliver up to five (5) amps of continuous current
to drive a very large system.
Inputs
• Station connections

3-4 Setup
This section provides the procedures for configuring your 2-pump, 12-station controller.
Configuration of your controller includes setting the number of stations and pumps, setting
variables such as convey time and blow-back interval, and setting up passwords. We
recommend that you carry out these procedures in the order given here.
To help you set up the controller quickly, this section walks you through the setup using the
menu system. This procedure will work for most applications, but you may need to perform
some minor adjustments afterwards to achieve the best conveying performance.
• High vacuum connections
• System error connections
• Station connections
• Pump/blowback
• Spare
Note: Before carrying out these procedures, install all equipment as

To access the Station Settings menu, place the controller in the OFFLINE state:
1. Press the ENTER/MENU key to enter the menu system.
2. Continue to press the ENTER/MENU key until the following screen displays:
STATION SETTINGS?
NO/YES
To enter the Station settings menu:
• Press the YES key.
To bring you up one level within any menu:
• Press the CLEAR key.
Operation Mode, Station Settings Menu
In most applications, each loading station can use different types of hoppers. The two
common types are standard hoppers and sight glass loaders. You’ll need to set up your
controller for the type of hopper you are using for each of the 12 loading stations.
The first submenu in the Station Settings menu is the Operation Mode.
To enter the Operation Mode submenu:
• Press the YES key at the following screen prompt.
OPERATION MODE?
NO/YES
Each station in the conveying system can be a standard configuration or a sight glass
configuration. Each hopper design operates in a slightly different manner.
In Standard mode, a flapper sensor detects a demand on the system. The volume fill sensor
senses when the hopper is filled with material. These two (2) sensors are wired in series and a
single input of the controller reads them. The controller determines the difference in the
signals, depending on load sequence timing.
In Sight Glass mode, only one single sensor detects demand. This mode has no volume fill
operation, and you’ll need to disable that function. Properly setting the operation mode lets
the controller correctly sequence station loading.
Upon entering the Operation Mode menu, the controller prompts you to set all 12 stations to
Normal (default) mode.
To set all the stations to Normal mode and return to the Station Settings menu:
• Press the YES key at the following screen prompt.
ALL NORMAL MODE?
NO/YES
This function lets you use the fast setup feature of the controller. Normal mode is the factory
default, so if no sight glass loaders are on your system, you won’t need to alter this setting.
Pressing the NO key moves to the All Sight Glass Mode screen. Again, this function lets you
quickly change all stations to Sight Glass mode if all stations have sight glass loaders.
ALL SIGHTGLASS MODE?
NO/YES
To move on to the individual settings screen:
• Press the NO key.
The following screen displays.
STATION: 1 NORMAL
Y=NORMAL N=SIGHTGLS
Starting with Hopper 1, the controller now lets you individually set the operation mode of
each station.
1. Press the YES key to set the station to Normal mode.
2. Press the NO key to set the station to the Sight Glass mode.
3. Press the SET key to save the new setting into controller memory and increment to
the next station in sequence.
4. Press the CLEAR key to exit to the Station Settings menu.
