DIAGNOSTIC & TROUBLESHOOTING
98
Top feedroll plastic stop worn out
or absent Check the condition of the red plastic feedroll stop. If worn out, there will be a direct
metal-metal contact that may cause severe vibrations.
Damaged or squeezed sensor
cable
Inspect the antenna cable over its whole length and on every angle. Measure the
resistance between each of the 3 antenna wires. Only the colored wire should display
readable value between 880-950 Ω. Repair and isolate the cable if necessary.
The sensor/antenna is damaged.
Electrical resistance between the colored wire is less than 800Ω or higher than 1kΩ
signaling that antenna coil wire are damaged or short. Or, there is a short circuit
between the signal wires and the ground. Or the epoxy casting holding the magnet-
coil assembly is broken or detached from the casing. Or the fasteners holding the
sensor on the shafts are damaged or loose.
With the PTO stopped and disconnected, turn on the control box and detector, then
set the harvester in forward. Check if vibrations or impacts on the feedroll causes
metal detections. Replace the antenna if necessary.
No metal detection
or abnormal
behavior.
(No alarm)
Damaged breakers, wires, bad
connections or failed controller. Check the wiring and all connectors. Make sure the control box power offers clean
12V. Consult technician for a controller field diagnostic with computer software tools.
The antenna cable is damaged or
cut
Inspect the antenna cable over its whole length and on every angle.
Measure the resistance between each of the 3 antenna wires. Only the colored wire
should display readable value between 880-950 Ω.
Repair and isolate the cable if necessary.
