The shredder uses two rotating cutting shafts,
which are driven by an electrical motor to shred
paper.

Electrical Operation

When the center power on switch is pressed,
all the LED warning symbols on the indicator

The shredder will now
be in standby mode and the “Power-on” symbol
on the indicator panel will be illuminated amber.
When the shredder is in standby mode and the the
cabinet door is opend,the normally closed door
adjar micro switch is opened and prevents power to
the motor until the door is closed.. When the bag full
sensor is triggered, the bag full icon will illuminate.
The control board will then disable the motor circuit
until the shredder bag is either cleared or emptied.

When the shredder is severely loaded down, the
control board will illuminate red and disable the

motor circuit.

Bag Full Flap Switch - The ap switch is a normally
open switch actuated by the bag full ap. When the
shred bag becomes full of shredded material, the
bag full ap is pushed back and power is then
removed from the motor circuit.

Paper Sensors - Located in the throat area consist­ing of two components, the emitter and receiver.

Emitter - Theinfraredlightbeamfromthelight emit­tingdiodeissensedbythereceivertoactivate/deac­tivate the control board.

Receiver - The receiver is a light activated diode,
which works in conjunction with the emitter to acti­vate/deactivate the control board.

g Electrical Components

Testin

WARNING!

Always disconnect the power cord from receptacle
before making continuity or resistance tests.

Electrical Components

Motor - Thermally protected motor designed for
continous operation.

Capacitor -AC motor run capacitor.
Power on/Auto feed on switch - The Power on

/Auto feed on switch, when depressed, connects
the hot and neutral circuits to electrical components
of the shredder.

Doorajar, Machine head safety switch - The safety
switch is a normally open micro switch which is
actuatedbya trigger locatedinsideofthecabinetdoor.
The switch is normally closed when the door is
closed and when the machine head is installed on the
cabinet.

Switches
Set meter to read resistance. Check switches for
continuityfromcommontoclosedcontactsand
ity from common to the open contact.

Emitter - Set meter to the diode setting. Disconnect
emitters from the control board. With the positive
meter probe on the emitter wire and the negative
meter probe on the black-stripped emitter wire,
check for approximately .639 ohms. Reverse the
meter leads and

should be read.

Receiver-Setmetertoread20Mohms. Disconnect
thereceiverfromthecontrol board. With thepositive
meter probe on thereceiver wire and the negative
meter probe on the receiver wire check for app­roximately 4.62 Mega ohms under normal room
light. The resistance will increase when blocked.
Reverse the meter leads and

should be read.

General Troubleshooting

Malfunction corrections are based on visual obser­vations made by the operator. The causes of the
malfunctions are isolated by the symptom of the
malfunction and noting at which point in the operat­ing cycle the malfunction occurred. Malfunctions
may be pinpointed toadefective electrical compo­nent or mechanical part by referring to the
Principles of Operation, the troubleshooting guide
and the wiring diagram.

TroubleshootingChart

The troubleshooting guide chart that follows is
arranged in order of the normal operational
sequence. Whenamalfunction occurs, read down
the SYMPTOM column until you
ate description for your symptom. Read the corre­sponding PROBABLE CAUSE, then perform the
recommended procedure in the CORRECTIVE
ACTION column. When replacing electrical compo­nents that have push on terminals, label the electri­cal leads that were removed, to facilitate reconnect
ing them. Refer to the wiring diagram
to resolve any wiring di

WARNING!

Always unplug the shredder to avoid possible elec­trical shock hazard before attempting to perform
any repairs.
