Possible cause
Reverse polarity.
Interruption in supply
current circuit.
Defective monitor
Power outage in the wires
of seed sensors or the
circuitry causes overload,
thus, the monitor limits or
switches off power output.
Damaged connecting leads
or loose connector causes
disturbance in power
supply.
Communication error
caused by a broken cable
or loose connector.
Sensor is blocked or
defective.
TROUBLESHOOTING
Resolution
Check polarity.
Check the power machine's
mains, fuse panel, etc.
Return it to the manufacturer or
one of its services.
Seek the cause of power outage
by visual inspection and moving
the cables. The defective part has
to be replaced.
Connect the sensors to the
monitor section by section to find
the unit where the green light
goes off. This one is the cause of
power outage.
Check whether the red LEDs on
seed sensors are on in normal
position. Disconnect the module
indicated with the first dark LED
in the sequence or the module
before this one. Check
connectors.
Check the first module indicated
as faulty or the module before
this one. Tighten connectors.
Carefully insert an object (e.g. a
screwdriver) into the sensor head.
The LED should be darkened for
a moment. If module does not
react, it has to be cleaned or
replaced.
