closed, main power switch pulled out,
nothing happens when START button
is pressed
No incoming power
Check by measuring voltage at power socket,
measure from phase to phase to phase – NOT to
ground.
Power cord or plug faulty Disassemble plug cap and check connections or
open electrical compartment and measure
voltage from terminals 1 to 2 to 3, do NOT
measure from either terminal to ground.
Safety guard switches not operating
With the electrical panel attached to the front of
the machine with the plate hook, temporarily
connect terminal 7 of relay K2 to ground. Turn
the machine on and press the START button. If
it starts, then one or both of the guard switches
were not operating. Remove the temporary
connection and open the main access panel.
Disconnect one guard switch at a time and
connect together the ends of the wires to which
the guard switch had been connected. Attempt
to start the machine; if it operates, the guard
switch just removed was faulty. Check to see if
the guard had been bent—forcing the magnet out
of the correct position. Replace the Reed Switch
if required.
Fuse, F5 blown
Check the fuse or replace with a known good
one.
