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.
1.
Check the SHEAR/NOTCH selector switch. The machine will not move unless the selector switch
is in either the SHEAR or the NOTCH position.
2.
Check the motor rotation. It should be counterclockwise when viewed from the shaft end of the
motor.
3.
Check the stroke control adjustment and make sure that only one limit switch is in contact with
the metering boss. If both limit switches are in contact with the metering boss, the machine will
not move. Loosen the stroke control handles and move the limit switches. Try the machine again.
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 8.1C.
6.
No power from the transformer: Check the voltage across the transformer secondary terminals. It
should read 110 to 120 volts.
7.
The solenoid on the control valve is not functioning. REFER TO SECTION 8.2.
8.
The foot pedal switch is not functioning properly. A voltage test may be run on the terminal strip
in the control box to determine if the foot switch is working properly.
►
WARNING: THERE IS LINE VOLTAGE PRESENT IN THE CONTROL BOX WHEN THE
MACHINE IS POWERED. THESE TESTS SHOULD BE PERFORMED BY A QUALIFIED
ELECTRICIAN.
To test the foot switch, power the machine and test the voltage between terminal #’s 9, 20, 21 & Ground.
Test the voltage between terminal #9 and Ground. The reading should be 110 to 120 volts.
This will determine that you have the proper voltage to the pedal.
With the pedal up, the voltage should read 110 to 120 volts between #20 and Ground. There should be no
voltage reading between #21 and Ground.
