IV. MAINTENANCE AND TROUBLESHOOTING
Your sowing control console is mostly an electronic device. Therefore it requires to be cared for. After sowing, store it in dry
premises.
Symptoms Probable cause Solution
1. The console does not
switch on. The diodes do
not light up upon power
on.
-The supply harness is
disconnected
-
Battery supplying insufficient
voltage.
-The fuse has blown.
-The console is faulty.
-Check it is connected to the tractor’s 3-pin outlet or the battery
(check that the lugs are clean and crimped properly).
-Check that the battery voltage ranges between 10 and 15 Volts.
-Check the fuse located on the console’s supply harness. Replace
it if necessary by a 5 AMPERE fuse.
Never fit a fuse with
higher amperage. If the fuse blows again, contact our after-sales
service.
-Call our after-sales service.
2. A diode is not lit
during the initial phase
after power-on.
- The console is faulty.
-Call our after-sales service.
3. When sowing, the
diodes most too the right
are lit red (with alarm
buzzer) whereas there is
no cell on these rows.
-The number of rows set exceeds
the actual number of rows
-In the menu setting the number of rows, set as many diodes as
there are rows. Disable monitoring for the non-existent rows.
4. A diode is inoperative
during sowing, it stays off
continuously.
-Monitoring of the cell was
disabled in the menu setting the
number of rows
- In the menu setting the number of rows, enable the diodes
corresponding to the cells to monitor.
5. When sowing all
diodes programmed are
lit red (with alarm buzzer)
-The alarm threshold value is too
high
-Reduce the value of the alarm threshold
6. A diode remains lit red
during sowing, the alarm
buzzes continuously
while the seeder element
dispenses the grains
properly.
-The sensor of the sowing
element is faulty.
-
Connection problem between
the sensor and the harness, or
between the harness and the
console.
-
The sensor or electric harness
has intermittent faults.
-Clean the sensor’s photoelectric cells properly with a brush. If
required, use water and a product to remove the film of sowing
treatment product deposited on the photoelectric cells.
-Check that all connectors are connected properly.
-Check that the electric harness is not pinched, worn or torn.
Swap the sensor indicating a fault with that of another row. If the
problem follows, the sensor is the cause of the fault. If the
problem does not follow, the harness or console is the cause of
the fault.
7. All diodes on the
console are lit during the
initialisation phase after
power-on, but no grain is
detected (no flashing
diode)
-The seeder harness is not
connected properly.
-The seeder harness is faulty.
(short-circuit)
-A sensor is faulty.
-The console is faulty.
-Check that the connector of the console, seeder and the
connectors of the sensors are connected properly.
-Check that the electric harness is not pinched, worn or torn.
Check that the sensor wires are not pinched, worn or torn.
-Call our after-sales service.
-Call our after-sales service.
CAUTION
Disconnect the console power supply before performing any welding operation on the tractor or the seeder to prevent the
system from being damaged.
