SAFETY WARNING
The following troubleshooting procedure may require that tests
be made with the electrical enclosures open and power turned
ON. These tests should only be conducted by authorized
personnel who are aware of the electrical and mechanical
hazards present.
The gathering brushes use an AC induction motor. It is
not a servo motor and it is not controlled by the CPU in
the tyer. This test should be done with the tyer's
gathering belts running. Start the tyer and turn the
BELTS/BRUSHES switch on the operator panel to ON.
Check CB5 and CB6
in the main electrical
box. Have they been
tripped?
Using a voltmeter, check for AC
voltage at motor leads. Check
motor nameplate for rating. Is
voltage present?
Some 220 VAC motors use a
capacitor. Check connections to it. If
OK, check wiring in junction box on
motor. If this is OK, replace the
motor.
Check voltage at CRE1 between
terminal 1 and wire 92 and
between terminal 2 and wire 92.
Repair AC wiring to
output of solid-state
relay.
Check DC voltage across the input
terminals of the solid-state relay which
controls the motor for the gathering
brushes .
Replace the
solid-state
relay.
Verify good connections P6:7 to the
positive terminal and also P6:23 to
the negative terminal. Is there
continuity?
Replace Main
board.
Repair faulty
wiring.
Reset the
breaker.
