TM 5-3610-286-20 Table 2-5. Organizational Troubleshooting (cont). Malfunction Test or inspection Corrective action 5. FEEDER BOARD DOES NOT LOWER INTO POSITION (cont). Step 4. Turn printing press main power switch to OFF. Using a muitimeter 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 multi meter 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 multimeter 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 c6: Point 13 and Point 14 Limit Switch b37: Point 50 and Point 51 Limit Switch b274: Point 50 and Point 50a If no voltage is observed, replace the faulty component (paragraphs 2-89, 2-93). If voltage is observed, go to step 7. NOTE Step 7 requires one person to depress main pile up pushbutton during performance. Step 7. Using a multi meter set to range higher than 115V ac, check for 115V ac between the points listed below for each component. Contactor c6 Point A1 and Point A2 2-3O
