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.
