Anleitung Zusammenfassung
The shredding of other metal items will damage the cutting blades. Plastic materials such as charge cards, covers, inserts and film may be shredded on a very limited basis However, extended shredding of such materials will prematurely dull the cutting blades The shredder control panel is shown in Figure 4-1. To start shredding, press the "ON" button then feed the material to be shredded into the throat of the shredder. Never exceed the maximum capacity of the shredder To tum the shredder off press the "OFF/REVERSE" button. When the shred bag becomes full, the bag full flap triggers a sensor which automatically turns the shredder off. To resume shredding, push the shreds down into the bag or install a new bag then press the "ON” button If too much paper is inserted into the feed throat of the 1246S-1, the shredder will automatically reverse eject the paper, then tum off. To resume shredding, REDUCE the number of sheets in the lift then depress the "ON" button To clear a severe jam that is not automatically ejected by the shredder, reverse the shredder by depressing the "OFF/REVERSE" button while pulling firmly on the paper in the throat. If there is not enough paper to grasp, rock the paper through the cutters by alternately depressing the "ON" and "OFF/REVERSE" buttons In case of a severe jam, the thermal overload circuit of the motor may be triggered causing the unit to appear to be "DEAD". Allow the motor to cool for a few minutes before attempting to clear the jam OFF/REVERSE On FIGURE 4.1 ORANGE ON SWITCH BLACK BLACK BLACK OFF/RE V SWITCH WHITE REO BLACK GREEN BLACK 5.0 TROUBLESHOOTING 5.1.1 Electrical Operation; 1246S-1 The 1246S-I electrical schematic/wiring diagram is shown in Figure 5-1. The electrical circuit is comprised of the following components. 1. ON Switch (SI). This momentary push button switch controls the forward mode of operation. In the "ON" position, current is applied to the motor by the Printed Circuit Board (PCB1). 2. OFF/REVERSE Switch (S2), This momentary push button switch controls the OFF mode of the shredder operation when depressed once then released. When the switch is depressed and held down the current is reversed causing a reverse rotation of the motor. 3. Flap Switch (S3). This switch is opened and power removed from the motor and circuit board whenever the shred bag becomes filled enough to raise the Bag Full Flap. 4. Capacitor (Cl). The 1246S-1 contains a 30 MF capacitor This capacitor is wired in series with the motor and assists the motor in both running and starting. 5. Motor (Ml). The 1246S-1 motor is a single phase, i/4 horsepower, 1650 RPM, continuous duty, AC motor. It is a permanent split capacitor three wire reversible motor with a no-load current draw of 2.4 Amps nominal and 6 4 Amps maximum. The motor is thermally protected. 6. Main Printed Circuit Board (PCB1). The P C. Board causes the motor to run in a forward direction when the "ON" Switch is actuated and turn off when the "OFF/REVERSE” is momentarily depressed. When the "OFF/REVERSE" Switch is held down PCB1 reverses direction of the motor. If the motor stops due to a jam, PCB1 will reverse the direction of the motor then shut off after the jam has been ejected. When the "ON" button is depressed, contacts A and B of SI close momentarily completing a circuit between PCB1-1 and PCB1-3. At this time the coil of the forward relay on the board latches causing the motor to run in the forward direction. When the "OFF/REVERSE" button is momentarily depressed the circuit is broken causing the unit to shut off When the shredder becomes full, the "BAG FULL" flap pushed up opening the normally closed contacts of the flap switch. The motor is disabled until the shredded paper is either pushed down into the bag or the full bag is replaced. If too much paper is inserted into the throat opening, the cutting head stalls forcing current on the reverse winding to drop, PCB-1 detects the change in current and activates the reverse relay on the board. The motor reverses direction to eject the paper. After the jam has been ejected the motor automatically shuts off. 5.0 TROUBLESHOOTING (Continued) 5.3 Troubleshooting Guide Chart SYMPTOM PROBABLE CAUSE CORRECTIVE ACTION Motor does not run.
