8.0 TROUBLE SHOOTING GUIDE
8.1 ELECTRICAL TROUBLESHOOTING:
PUNCH/TOOL STATION
►
CAUTION: ALL ELECTRICAL WORK PERFORMED ON THIS MACHINE
SHOULD BE PERFORMED BY A QUALIFIED ELECTRICIAN.
A.
MOTOR WILL NOT RUN:
1.
Check the PUNCH/TOOL and SHEAR/NOTCH selector switches. The machine will not start
unless both selector switches are in the START position.
2.
Check the disconnect switch. Make sure that it is in the ON position.
3.
Check the emergency stop palm buttons. A defective or stuck emergency stop button will not allow
the machine to be powered. Check the emergency stop buttons with an Ohm meter. With the
switch in its normal position, the reading should show continuity from one terminal to the other.
DO NOT OPERATE THIS MACHINE WITH THE EMERGENCY STOP BUTTONS BYPASSED!!
4.
Check to be sure that plant voltage and phase correspond to the machine voltage and phase.
5.
Check the line wiring connections at the starter. FOR THE WIRING DIAGRAM,
SEE SECTION 10.
6.
Check the line voltage at the starter. If the correct line voltage is present at the starter, either the
starter or the motor is defective. Contact your local dealer or the factory.
B.
THE MOTOR RUNS BUT THE MACHINE WILL NOT CYCLE WHEN DEPRESSING THE
FOOT PEDAL.
NOTE: MAKE SURE THE CORD FROM THE FOOT PEDAL IS IN GOOD
CONDITION. IF IT HAS BEEN PINCHED OR CUT - REPLACE IT!!
1.
Check the PUNCH/TOOL selector switch. The machine will not move unless the selector switch is
in either the PUNCH or the TOOL position.
2.
Check the motor rotation. It should be counterclockwise when viewed from the shaft end of the
motor.
3.
Check the run/jog switch. The foot pedal will not operate the machine when this switch is in the
JOG position.
4.
Check the fuses in the control box. There are two fuses on the primary side of the transformer and
one on the secondary side. Remove the fuses and check them with an Ohm meter.
5.
Check the limit switches. FOR PROCEDURES, REFER TO SECTION 8.1B.
6.
No power from the transformer: Check the voltage across the transformer secondary terminals. It
should read 110 to 120 volts.
