Solution
Machine will
not turn on
Circuit Breaker Tripped
Check VDC between Terminals T-42 (+) and T-2 (-) and they
should read 24VDC. If not correct change out Clean
24vdc power supply. Check to see if the green start push
button lights up when depressed. If the push button lights
up but motor will not start, manually depress the button on
the Mag Starter. If the motor starts then go to next step. If
the motor does not start replace Mag Starter.
Machine turns
on but motor
does not
start.
Overload relay tripped
Reset overload relay. If Overload relay trips again check to
insure the correct volts are being supplied to the machine.
Check wires going to the motor for any signs of damage or
loose connections.
Inspect connections at motor for tightness and inspect
ground terminal for tightness. If ok change out motor. If not
ok fix problem and retest.
No voltage going to
motor.
Check for voltage at overload relay. If no voltage present on
discharge side, change out overload relay. If voltage is
present go to next step.
Check connections at motor for tightness and check ground
screw for tightness. If ok , check for voltage at motor. If ok,
change out motor. If not ok inspect wiring for damage.
Mag Starter shorted
Check to see if the green start push button lights up when
depressed. If the push button lights up but motor will not
start, manually depress the button on the Mag Starter. If the
motor starts then go to next step. If the motor does not
start replace Mag Starter.
Check for 24vdc at terminal 14 on the Mag Starter. If there
is no voltage, check F6 fuse for damage. If there is 24 vdc go
to next step.
Check for 24vdc at terminal 3 on the Green start push
button. If there is no voltage check wire from terminal 14 on
the Mag starter to terminal 3 on the green start push
button for damage. If there is voltage go to next step.
Check for 24vdc at terminal 4 on the green start push
button when it is depressed. If there is no voltage, change
out start push button. If there is voltage present then check
the wire condition from terminal number 4 on the green
push button to terminal 13 on the Mag starter for damage.
Also check the P.C fan motor for continuity. The fan motor
connects to the start push button on terminals X1 positive
and X2 negative.
