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 (cont). NOTE Main pile up pushbutton must be pressed to perform this step. Step 4. Turn printing press main power switch to OFF. Using a multimeter set to ohms range, perform continuity check on main pileup (b20) and main pile down (b21) switches. If no continuity, replace defective switch (para. 2-94). If continuity, go to step 5. Step 5. Using a multimeter set to range higher than 115V ac, check for 115V ac between the points listed below for each motor protection switch. a6: Point 13 and Point 14 a8: Point 13 and Point 14 a40: Point 13 and Point 14 If no voltage is observed, replace the faulty switch (para 2-93). If voltage is observed, go to step 6. Step 6. Using a multi meter set to range higher than 115V ac, check for 115V ac between the points listed below for each component in the limit switch circuit. Contactor c5a: Point A1 and Point A2 Limit Switch b87: Point 156 and Point 170 Limit Switch b36: Point 123 and Point 156 Safety Limit Switch b89: Point 123 and Point 126 Safety Limit Switch b90: Point 47 and Point 126 If no voltage is observed, replace the faulty component (para. 2-89). If voltage is observed, go to step 7. 2-27
