TROUBLESHOOTING
Malfunction Possible cause Resolution
Device cannot be switched
on.
Stand-by LED (red light on
the left) is off.
Reverse polarity.
Interruption in supply
current circuit.
Defective monitor Check polarity.
Check the power machine’s
mains, fuse panel, etc.
Return it to the manufacturer or
one of its services.
The green "POWER ON"
LED is off or flashes but
then goes off. Power outage in the wires
of seed sensors or the
circuitry causes overload,
thus, the monitor limits or
switches off power output. 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.
The monitor does not
detect some or all of the
seed sensors during the
Test. Some of the seed
sensor LEDs is off. Damaged connecting leads
or loose connector causes
disturbance in power
supply. 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.
The monitor does not
detect some of the seed
sensors during the TEST.
The sensors are indicated
with red light. Communication error
caused by a broken cable
or loose connector. Check the first module indicated
as faulty or the module before
this one. Tighten connectors.
Sensor does not indicate
drilling, seeds are not
sensed. TEST indicates
high dust level. Sensor is blocked or
defective. 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.
