TM 5-3610-286-20 Table 2-5. Organizational Troubleshooting (cont). Malfunction Test or inspection Corrective action 4. FEEDER BOARD DOES NOT RAISE INTO POSITION. WARNING HIGH VOLTAGE • Do not operate printing press until you are sure TSS Press Section is connected to a suitable ground. Failure to do so may result in death or serious injury. • Shut off power source before attempting to disconnect, service, or con- nect wires or cables. Failure to do so may result in death or serious injury. • When working on high-voltage components, always have an additional person present, and keep one hand away from equipment to reduce hazard of current flowing through vital organs of body. Remove all jewelry from fingers, wrists, and neck prior to working on electrical components. Failure to do so may result in death or serious burns. Step 1. Visually check for mechanical binding of chains, sprockets, or guides of pile lift mechanism. Adjust, repair, or replace components (para. 2-90). Step 2. Turn panel breakers and main power switch ON. Check that feeder motor circuit breaker is ON. Press contactor (c5a) button in. If motor does not operate, go to step 3. If motor operates, go to step 4. NOTE Main pile up pushbutton must be pressed to perform this step. Step 3. Using a multimeter set to range higher than 24V dc, check for 24V dc at point 161 and negative ( - ) on terminal strip. If power is present, go to step 4. If power is not present, replace main pile feeder brake (s7), (figure FO-1 and para. 2-90). 2-26
