1 General Information

1-1 Equipment Function

Sterling conveying 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 Sterling 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 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 9 of 60

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 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 12 of 60

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 13 of 60

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 SCC4/38 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 proved 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 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.

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 15 of 60

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 SCC4-38
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 SCC4-38
Controller. Failure to do so may result in serious injury. No one but
the person who installed the lockout may remove it.
