PROBLEM
PROBABLE CAUSE
SOLUTIONS
The «beep» and alarm light
are continuous.
Check position of jumpers.
They should, by default, be
in the OFF position on J6
and in the “BOLT” position
on J8. The ON position on
J6 is used when optional
motion detectors are in-
stalled on the cutter head
and the feed rolls. In this
case, choose, on J8, the
type of clutch on the trans-
mission shaft between the
transmission and the cutter
head.
Check position of jumpers on the electronic board
of the metal detector.
The transmission shifts
directly to REVERSE follow-
ing a metal detection.
Bad power supply.
NEUTRAL - REVERSE sensors are not properly
adjusted or they are defective. The electronic
board is defective. The electronic board should be
serviced by a qualified technician approved by the
manufacturer.
The safety reset button
of the metal detector box
switches to the OFF posi-
tion.
Power supply connections
inverted.
Sensor wire shorted.
Check polarity of connections. White is positive (+)
Check transmission sensor wire for damages.
Turn off device, disconnect sensor connector on
the electronic board, switch device on. If you still
have the problem,
check the other wires, if not, the problem comes
from the sensor wire.
The safety reset button in
the tractor cab switches to
the OFF position.
Power supply connections
inverted. Damaged wiring
cable.
Check polarity of connections. Carefully repair wir-
ing. Check for continuous current between positive
connector and machine frame.

The lower front feed roll
bearings are defective
causing the roll to touch the
antenna.
The feed rolls turn at
maximum speed.
The maximum speed is
obtained when:

length of cut.
• Use of a 11.3 in dia pul-
ley on the corner trans-
mission.
Replace the lower front feeding roll bearings.
Check feed roll bumpers, they may be touching
each other.
Check antenna.
Move jumper J9 from position G=100 to position
G=50 (G for Gain)
The solenoid retracts iedi-
ately when switch in turned
