Step 3.
Step 4.
Step 5.
Set SAFETY STOP PUSHBUTTONS and MACHINE SAFE PUSHBUTTONS to proper
operating positions. Ensure that cylinder guard switch (b135), defIector safety
limit switch (b30), ink unit safety guard switch (b26), form roller limit switch
(b31), and plexiguard limit switch (b42) are in operate position to allow press to
run.
Using a multimeter set to range higher than 120V ac, check for 120V ac between
input side of fuses (e3) and ground (refer to figure FO-1).
If power is present, go to step 4.
if no power is present, go to step 3.
Turn main power switch OFF. Using a multimeter set to ohms scale, check
continuity of wire between main power switch and fuses (e3).
If continuity is present, check that main panel breakers are ON.
If no continuity, replace wiring.
Using a multimeter set to range higher than 120V ac, check for 120V ac between
output side of fuses (e3) and ground (figure FO-1).
If power is present, go to step 5.
If no power is present replace fuses (e3) (para. 2-93).
Using a multimeter set to range higher than 120V ac, check for 120V ac between
point L1 of input side of contactor (c2) and ground, and repeat for points L2
and L3.
If power is present, go to step 6.
If no power is present, replace wiring (figure FO-1).
