1 General Information

1-1 Equipment Function

Sterling systems create vacuum for conveying pelletized or
granular material in a central material handling system.

A typical use is an in-plant distribution system for plastic
processing plants.

1-2 Necessary Documents

The documents below are necessary for proper installation,
operation and maintenance of conveying systems. You can
obtain additional copies from the Service Department at
Sterling. Make sure that the appropriate personnel are

familiar with these documents:

• This product manual.

• The Sterling SPD/SPC Series product manual.

• Electrical schematic and connection diagrams.

• Blower and electric motor information sheets.

• Operation and Installation manuals for all electrical

components.

1-3 System Capabilities

Sterling central vacuum systems are as varied as the
applications they service. The tubing and equipment
furnished in a Sterling system are designed to convey the
material(s) specified at the time of purchase at specific rates
and distances.

Sterling 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.

Page 8 of 38

Use the minimum effective amount of vinyl flex hose to
maximize material line efficiency. Keep material lines as
straight as possible. Refer to the Sterling SPD/SPC Series
Product Manual (Sterling Part No. A0571050) for installation
recommendations.

Important! Vacuum leaks occurring anywhere in your system reduce capacity.

1-4 Equipment Cycle

Sterling material conveying systems are used for automatic
pneumatic handling of most free-flowing, dry, pelletized, or
granular materials. Material characteristics determine the
type of equipment needed to convey the material.

2 Safety

2-1 Work Rules

The installation, operation, and maintenance of this
equipment must be conducted in accordance with all appli­cable work and safety codes for the installation location. This
may include, but is not limited to OSHA, NEC, CSA, SPI,
and any other local, national, and international regulations.

; Read and follow these operating instructions when

installing, operating, and maintaining this equipment. If
the instructions become damaged or unreadable,
additional copies are available from Sterling.

; Only qualified personnel familiar with this equipment

should work with this system.

; Work only with approved tools and devices.
; Disconnect and lock out power while working on this

equipment.

2-2 Tools and Equipment Needed

These tools and equipment are necessary for installation:

; Hand tools.
; Wire, conduit, and fittings for wiring runs.
; Anchor bolts with nuts and washers or red head-type

anchors.

2-3 Safety Considerations

The terms NOTICE, CAUTION, WARNING, and DANGER
have specific meanings in this manual.

NOTICE is used to indicate a statement of company policy
directly or indirectly related to the safety of personnel or
protection of property.

CAUTION indicates a potentially hazardous situation which,
if not avoided, may result in minor injury.

WARNING indicates a potentially hazardous situation which,
if not avoided, could result in death or serious injury.

Page 11 of 38

DANGER indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
This word will be limited to the most serious situations.

The term IMPORTANT emphasizes areas where equipment
damage could result, or provides additional information to

2-3-1 Reporting a Safety Defect

make a step or procedure easier to understand. Disregarding
information marked IMPORTANT would not be likely to

cause personal injury.

If you believe that your equipment has a defect that could
cause injury, you should immediately discontinue its use and
inform Sterling.

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.

2-4 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.

Page 12 of 38

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.

2-5 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 co­workers to promote safe practices. Immediately report any
potentially dangerous situation to your supervisor or
appropriate person.

2-6 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.

2-7 Safety Devices

This section includes information on safety devices and
procedures that are inherent to the SSC1-5Q 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.

2-7-1 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 SPD/SPC 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.

2-7-2 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

Page 14 of 38

guarding a motor, and the safety switch fails, the motor
should not be able to run.

2-7-3 Safety Device Lock-Outs

Some safety devices disconnect electrical energy from a
circuit. The safety devices that are used in the SSC1-5Q
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 SSC1-5Q
Controller. Failure to do so may result in serious injury. No one but
the person who installed the lockout may remove it.

4 Installation

4-1 Installing the SCC1-5Q Control Panel

Note: Before you mount the panel, consider how you run wiring to

the vacuum receivers, 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.

4-2 Making 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.

4-3 Making SSC1-5Q Control Panel Power Drop Wiring

Connections

Hardwire the input power at 110/1/50-60 VAC or 230V/1/50­60 VAC, depending on the specifications, which are located
on the SSC1-5Q Control Panel Serial Tag. The main power
switch is located on the right side of the enclosure.

Important! Sterling recommends that you protect PLC memory by providing

the control panel with a dedicated circuit, a true earth ground, and
a spike/surge protector.

4-4 Connecting the Control Panel to Vacuum Receivers

1. On 24 VDC control voltage systems, run a common +24
VDC wire and a common 0 (zero) VDC wire from the
controller to each vacuum receiver in the SSC system.

2. On all systems, run two wires to each vacuum receiver:
one each from the controller to the Bin-Full switch (LS)
and to the Atmospheric/Sequence-T solenoid (SOL)
valve.

3. Make sure that the solenoid and the proximity switch (if
supplied) on vacuum receivers are the same voltage (24

Page 19 of 38

VDC) as the SSC control panel voltage. Consult the
control panel serial tag and the solenoid valve
nameplates.

4. Wire size depends on control voltage, distance, number
of vacuum receivers, and the number of wires in each
raceway. Consult a qualified electrician.

5. Properly ground each receiver to reduce static build up
generated by material conveying.

4-5 Connecting the Control Panel to the Pump Package

1. Wire the pump package motor starter coil (M) to the
terminal provided in the SSC control panel enclosure.

2. Wire the pump package vacuum relief valve solenoid
(SOL A) to the terminal provided in the SSC control
panel enclosure.

3. Wire the pump package vacuum switch (VS) to the
terminal located in the SSC control panel enclosure (If
provided).

4. On SPDB pumps, wire the pump package blowback
solenoid (SOL B) to the terminal located in the SSC
control panel enclosure.

Wire the pump package motor overload to the terminal
provided in the SSC control panel enclosure.

5. On 24 VDC control voltage systems, run a common +24
VDC wire and a common 0 (zero) VDC wire from the
controller to each pump package in the conveying
system.

4-6 Special Timed Convey

Connect +24 VDC to inputs 11-15, corresponding to Stations
1-5, to enable the Special Timed Convey feature.

5 Using the Controller

5-1 Introduction

This chapter gives the procedures for configuring your
SSC1-5Q controller.

Configuration of your SSC1-50Q controller includes setting
the number of stations, setting variables such as convey
time and blow-back interval. Sterling recommends that you
carry out these procedures in the order given here.

5-2 Setup

Important! Before carrying out these procedures, install all equipment as

described in Chapter 4: “Installation”, and in the manual SPD/SPC
Series Conveying Systems.

5-2-1 Setting Up the System

This section provides an overview of the controller screens used in
configuring the system. Section 6 provides a detailed explanation of the
features listed on each screen.

5-2-1-1 Basic Menus and Setup of Controller

Once power has been applied to a properly installed
system, turn the disconnect switch to the ON position.
The alpha controller will display the screen for receiver 1

(Hopper 1).

Page 21 of 38

Important!

This screen allows the operator to adjust the convey time
(CONVEY), dump delay (DUMP), and the number of tries
before the no convy alarm activates (NO CONVEY).

To disable a station, set the convey time to 0 (zero).

DO NOT set the Dump delay or No Convey to 0 (zero).

To set the parameters for each receiver, use the left (◄)
or right (►) arrow keys to scroll through the settings for
the next (►) or previous (◄) receiver.

5-2-1-1-1 Setting Pump Parameters

To access the pump screen, press the right
arrow key (►) when in the station 5 screen or
press the left arrow key (◄) when in the
blowback screen.

This screen allows the operator to adjust the
pump motor ramp up/ramp down time (RAMP)
and the amount of time the pump runs unloaded
before shutting off (IDLE).

Important!

DO NOT set the Idle Time or Ramp time to 0 (Zero).

5-2-1-1-2 Setting Blowback Parameters

Once the pump parameters have been set, the
blowback parameters will need to be configured.
This screen can be accessed for each station,
by pressing the right arrow key (►) when in the
pump parameters screen (RAMP and IDLE
times are displayed).

This screen allows the operator to adjust all
those settings related to cleaning the filter
chamber: the number of conveys before
blowback (CNV>BB), the duration between
blowback pules (BB OFF), the duration of the
pulse (BB ON), and the number of cleaning
pulses (BB CYC).

Page 22 of 38

Important!

Setting either the CNV>BB or BB CYC parameters to “0” will disable
the blowback feature. DO NOT set other blowback parameters to “0.”

5-2-1-1-3 Input and Output Screen Features

To access the I/O screen, press the right arrow
key (►) when the Blowback Parameter screen
is displayed or the left arrow key (◄) when the
Convey/Dump/No Convey screen is displayed.

The I/O screen allows a service technician to
view the status of the controller’s inputs and
outputs during operation.

5-2-1-1-4 Changing Parameters

To change the settings in the Conveying, Pump
Parameters, or Blowback screens {To access
the required screen, press the right (►) or the
left arrow key (◄)}, the following operations will
need to be performed:

1. When the controller is in the menu screen
of the feature you wish to configure, press
the up (▲) and down (▼) arrow keys to
select the value you wish to change. (The
parameter value will flash when selected.)

2. Use the Plus (+) key to increase the value
or the Minus (-) key to decrease the value.

3. Press the OK key to update and accept the
new value entered.

4. Press the ESC key to cancel the
parameters you entered and return the
values to the previous settings.

Page 23 of 38

1. Press the green START pushbutton in. The controller
will display “✷✷✷” in the lower right corner of station and
pump setup screens.

Once the system has been started, each active station is
polled in sequence for a demand signal. The convey
sequence upon initiation, will continue until the set
convey time has elapsed or the demand signal stops,
whichever happens first. If the Special Timed Convey
feature is enabled, conveying will continue until the
convey time has elapsed. (Once station dump delay has
been initiated during the convey sequence, a new
demand signal will be ignored.) If the blowback
sequence begins immediately following the convey
sequence, the sequence valve will remain open
throughout the blowback sequence.

2. If during operation, a station conveys the specified
number of consecutive times without clearing the
demand signal, the NO CONVEY alarm will activate.
Press the ALARM SILENCE pushbutton and hold it in to
clear the alarm. The no convey alarm will sound in
LONG TONES.

3. Should the high vacuum pressure switch activate, the

HIGH VACUUM alarm will sound. Press the ALARM
SILENCE pushbutton and hold it in to clear the alarm.

The high vaccum alarm will sound in SHORT TONES.

4. If the pump motor contactor fails or the pump motor
overload trips, the PUMP FAULT alarm will be activated.

6 Configurable Settings

This section describes the proper setup of the SSC1-5Q
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 Options for Station Setup

Name Description Default

Conveying Components
Convey time

(CONVEY)

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.)

15 sec.

Dump delay

(DUMP)

No convey

(NO CONVEY)

Adjust this value to match the actual time needed to fill the
station. To disable a station, set the convey time to Ø

(zero).

Length of time allowed for material to drain from the station into
the receiver. The controller will not attempt to deliver more
material to the station until this time has elapsed.

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. DO NOT SET TO “Ø”.
The controller issues a “no convey” alarm if it has repeatedly
attempted to convey material to the station but the flapper
never opened during the dump delay. (The number of attempts
is controlled by this setting.)
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. DO NOT SET TO “Ø”.

10 sec.

6-2 Options for Pump Setup

The ramp time represents the amount of time it takes for the
vacuum blower to come up to full speed once it has been
turned on. The ramp down time represents the amount of
time it takes the blower to stop once it has been turned off.

The ramp up time lets the blower reach full speed unloaded.
When the ramp up time is reached, the vent valve will open
and allow the pump to draw a vacuum on the main vacuum
line. This in turn will open the receiver sequence valve
connected to the main vacuum line and allow material to be
drawn into the vacuum receiver.

The ramp down time allows the vacuum blower to come to a
full stop before it can be started again. This prevents the
blower motor from becoming a generator and blowing fuses.

Length of time the pump continues to run unloaded without
demand from any station. After this time has elapsed, the pump
shuts down to save power and to prevent wear on the pump.
Adjust this setting to fit the needs of your facility in trading off the
savings against the costs associated with waiting for a pump to

This feature specifies the time (in seconds) allowed for the pump
motor to come to a complete stop.
When this option is enabled, the controller periodically sends
compressed air backward through the pump’s air filter to dislodge
accumulated dust and debris.
Enable this option if and only if the pump has the equipment for
compressed-air filter cleaning. Set to Ø to Disable Blowback.
