Safety Considerations

AEC OFC Series extrusion control systems are designed to provide safe and reliable operation
when installed and operated within design specifications and national and local safety codes.

To avoid possible injury or equipment damage when installing or operating this equipment,
always use good judgment and follow these safe practices:

; Follow all SAFETY CODES.

; Keep fingers away from slide gates, augers, clean-outs, and calibration hatches.

Because automatic operation may start unexpectedly, A PINCH HAZARD
CAPABLE OF CAUSING BODILY INJURY EXISTS ANY TIME THE
POWER IS ON.

; Wear SAFETY GLASSES and WORK GLOVES.

; Use care when installing, operating or servicing this unit.

; Disconnect and/or lock out power before servicing or maintaining the blender.

; Use care when LOADING, UNLOADING, RIGGING, or MOVING this

equipment.

; Operate this equipment within design specifications.

; OPEN, TAG, and LOCK ALL DISCONNECTS before working on equipment.

You should remove the fuses and carry them with you.

; Disconnect and lock out power and compressed air before attempting to clean out

an auger and slide gate area.

; NEVER PUT FINGERS OR TOOLS IN AN AUGER OR SLIDE GATE

AREA.

; Make sure the blender and components are properly GROUNDED before you

switch on power.

; Do not jump or bypass any electrical safety control.

; Do not jump or bypass any pneumatic safety control.

; Do not restore power until you remove all tools, test equipment, etc. and until the

blender and related equipment is fully assembled.

; Only PROPERLY TRAINED personnel familiar with the warnings and

instructions in this manual should work on this equipment.

1 General Information

1-1 Introduction

This manual contains the basic information needed to operate and maintain our
standard AEC OFC Series extrusion control units.

The OFC extrusion control unit is a state of the art, simple to operate system that learns
the extruder rate and adjusts either the haul off or extruder speed to maintain a preset
weight per length. The units will self adjust to keep the product weight per length
adjusted for extruder throughput variations.

1-2 Necessary Documents

The items listed below are required for installation, operation, and maintenance of an
AEC OFC Series extrusion control unit. Additional copies are available from AEC.
Familiarize the appropriate personnel with these documents:

; This Service manual.

; The Customer Parts List.

; Operation and Installation manuals for accessories and options selected by the

customer, where installed.

2-4 Safety Considerations

The terms NOTICE, CAUTION, WARNING, and DANGER
have specific meanings in this manual. See Section 9 for a

complete list of specific safety warning information.

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

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

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

A 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 situation(s).

The term IMPORTANT emphasizes areas where equipment
damage could result, or provides additional information to make a
step or procedure easier to understand. Disregarding information
marked IMPORTANT would not be likely to cause personal
injury.

REPORTING A SAFETY DEFECT

NOTE: If you believe that your equipment has a defect which could cause

injury, you should immediately discontinue its use and inform
AEC, Inc., at our address listed in this manual.

The principle factors which can result in injury are:

1. Failure to follow proper operating and clean-out procedures,

i.e. lockout/tagout.

2. Failure to maintain a clean and safe working environment.
