7.
The solenoid on the control valve is not functioning: REFER TO SECTION 8.3.
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, place the selector switch in the START position and power the
machine. Place the selector switch in the PUNCH or the SHEAR position and test the voltage between
terminal #’s 1, 2, 3 & ground. A test between terminal 1 and ground will determine if there is voltage
present to the pedal. The reading should be 110-120 volt. With the pedal up, the voltage should read
110-120V between #’s 2 & ground. There should be no voltage reading between #’s 3 & ground. With the
pedal depressed, the voltage should read 110-120V between #’s 3 & ground. There should be no voltage
reading between #’s 2 & ground. If these readings are not correct, continue on with the following steps:
A.
Turn the machine’s power off at the disconnect switch. Remove the cover on the foot switch and
check for any loose connections.
B.
Make sure that the switches are adjusted properly. (You should hear two distinct "clicks" when
depressing the pedal.) There is a set screw adjustment on the pedal shaft to adjust the switches.
C.
Check the switches with an Ohm meter.
9.
Damage to the foot pedal cord: Check the continuity of the wire in the cord with an Ohm meter.
Make sure that the power to the machine is off and locked out. The wires must be disconnected from
the pedal and the terminal blocks.
10. The pump to motor coupler is damaged: Loosen the set screws in the pump and motor flanges and
slide them apart. Inspect the coupler; if it’s damaged, replace it.
8.2 LIMIT SWITCH INSPECTION
The limit switches are sealed units and cannot be taken apart. The plunger can be manually checked.
It should move freely in and out. The switches can also be tested with an Ohm meter.
The wires must be disconnected from the terminal blocks and the power to the machine off.
With the plunger out, the switch should read continuity; with the plunger depressed, it should read open.
