GUARDS FAILED
or
GUARD SW TIMEOUT
This message refers to the guards included on
the bench version of this machine. When the
main guard interlock and the insert guard
interlock do not open or close at the same time,
this message is displayed. In this machine, the
guard switch circuits are controlled by jumpers
located in connector J2.
Check that the jumper is installed connecting
positions 4 and 5 of J2. Also, check that the
jumper is installed connecting positions 13 and
14 of J2. Verify that the contacts are fully seated
in the connector. Clear the error and attempt to
cycle the machine.
Clear the error and attempt to cycle the machine.
GUARDS NOT CLOSED
The manual cycle button was pressed while the
guards were opened. This message refers to the
guards included on the bench version of this
machine. In this machine, the guard switch
circuits are controlled by jumpers located in
connector J2.
Check that the jumper is installed connecting
positions 4 and 5 of J2. Also, check that the
jumper is installed connecting positions 13 and
14 of J2. Verify that the contacts are fully seated
in the connector.
Clear the error and attempt to cycle the machine.
MOTOR FAULTED
The terminating machine detected a problem with
the motor drive circuit.
Contact a Field Service Specialist.
MOTOR OVER TEMP
The motor temperature switch (located inside the
fan shroud) has opened.
Check that the connector located on top of the
fan shroud did not come off. Verify that contacts
are fully seated.
Check for overheating of the motor. Check and
clean the filter screen and motor ventilation slots.
Verify proper operation of the motor temperature
switch—normally closed; opens at 49°C±3°C
[120°F±5°F].
The terminating machine cannot be cycled (the
error will not clear) until the problem with the
temperature switch is corrected.
MOTOR RELAY OPEN
The motor relay circuit (connected to parent
interface connector J3) has opened.
Check for the proper seating of the contacts in
connector J3. Make sure that the contacts in
jumper positions 11 and 22 and 16 and 24 have
not backed out of the housing.
Reset the error and retry cycling machine.
SW 1 NOT UNMADE
During a normal cycle, the braking switch (SW 1)
turns on and then is expected to turn off again. If
by the end of the cycle SW 1 has not turned off,
this error message is displayed.
Check for proper alignment of the vane as it
rotates through the switch. If the vane has struck
the switch, it may need to be replaced.
With a voltmeter, electrically check the switch
circuit in the following fashion:
CAUTION: Do not disconnect the vane switch to
perform this check.
1) With terminating machine power ON, check
between contacts 1 and 2 of the vane switch
connector—the reading should be between 22
and 24 Vdc. If no or low voltage is present,
contact a Field Service Specialist.
2) With terminating machine power on, check
between contacts 3 and 2 of the vane switch
connector. Remove the rear cover so the pulley
can be manually rotated. Allow the vane to move
in and out of the gap of the switch under test.
With no vane in the gap, the reading should be
between .03 and .40 Vdc. With a vane in the gap,
the reading should be between 22 and 24 Vdc.
