Operational Check and Adjustments
If the feeder is not operating correctly, see the
following operating malfunctions for instructions.
NOTE: The separator must be engaged and the
operator must be in the seat to engage the feeder.
1. Feeder does not engage at all. This indicates
that there is no power to the feeder clutch
solenoid or there is no signal to the controller
from the seat switch. Check the following:
A. Check for a blown fuse (Number 10).
Replace as required.
B. The switch in the operator’s seat may have
disengaged the feeder drive. Reset the
feeder clutch switch by turning OFF and ON
to permit operation of the feeder.
2. Feeder runs for approximately four (4) seconds
and disengages. This indicates that the
instrumentation is not getting a signal from the
feeder speed sensor (1). Check the following
items:
A. Check for damage to the sensor (1) or
connecting wires.
B. Check the clearance between the sensor (1)
and the signal sprocket (2). The correct
clearance is 0.25 to 1.5 mm (0.010 to 0.060
inch).
If necessary, temporarily bypass the Automatic
Feeder Cutoff.
NOTE: If the operator leaves the seat for more than
7 seconds, the feeder will disengage. The operator
must be in the seat and cycle the feeder clutch switch
to reengage the feeder.
NOTE: The feeder speed sensor (1) is located
opposite the signal sprocket (2) on the Left side of
the feeder housing or on the rock trap idler arm.
