Electrical Operation Bag Full Flap Switch - The flap switch is a normally open switch actuated by the bag full flap. When the shred bag becomes full of shredded material, the bag full flap is pushed back and power is then removed from the motor circuit. 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. Paper Sensors - Located in the throat area consisting of two components, the emitter and receiver. When the shredder is severely loaded down, the control board will illuminate red and disable the motor circuit. WARNING! Always disconnect the power cord from receptacle before making continuity or resistance tests. Electrical Components Switches Set meter to read resistance. Check switches for continuity from common to closed contacts and ity from common to the open contact. 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. Door ajar, Machine head safety switch - The safety switch is a normally open micro switch which is actuated by a trigger located inside of the cabinet door. The switch is normally closed when the door is closed and when the machine head is installed on the cabinet. Emitter - The infrared light beam from the light emitting diode is sensed by the receiver to activate/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. Testing Electrical Components 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 - Set meter to read 20M ohms. Disconnect the receiver from the control board. With the positive meter probe on the receiver 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. should be read. Reverse the meter leads and 8 3 5.0 TTroubleshooting General Troubleshooting Troubleshooting Chart 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 to a defective electrical component or mechanical part by referring to the Principles of Operation, the troubleshooting guide and the wiring diagram. The troubleshooting guide chart that follows is arranged in order of the normal operational sequence. When a malfunction occurs, read down the approprithe 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 on page 6 to resolve any wiring di culties that may occur. WARNING! Always unplug the shredder to avoid possible electrical shock hazard before attempting to perform any repairs. 4 5.0 Troubleshooting 5 Shredder Does Not Operate, No Indication Of Power Power Cord Disconnected.
