A command does not respond, whilst the other commands function normally:
1)
Check if the command from the console is sent to the coil of the solenoid valve of the manoeuvre. In order to check:
keep the power supply to the system on; the PTO of the tractor must not be enabled and the parking brake of
the tractor must be engaged.
2)
With a tester check if voltage reaches the coil of the solenoid valve when the electric command is operated. If no
voltage reaches it, it means that the console wire to the control unit or the console button is causing problems.
Contact an Authorised Ferri Assistance Centre.
3)
Check the wiring from the control unit to the connector. Remove the connector and use a tester to check that the
connectors of the distributor are being powered by the control unit. Check whether the console command is
followed by a corresponding voltage output on the connector of the control unit (the pinout of the connector is
shown below). If there is no voltage coming out of the control unit, the problem is located inside the control unit.
Contact an Authorised Ferri Assistance Centre.
4)
If there is no voltage, check that the wiring is intact. Check whether the command on the console is followed by a
corresponding voltage on the connector of the coil of the solenoid valve of the same command. If no voltage
reaches it, the problem is with the wiring. Contact an Authorised Ferri Assistance Centre.
5)
If there is voltage present, there may be a problem with the solenoid valve of the distributor. Check whether the coil
is intact. In order to check, replace the coil of the manoeuvre that is presenting the problem with another coil.
If the problem does not persist and exists in the manoeuvre with the replaced coil, the problem is with the coil.
Contact an Authorised Ferri Assistance Centre.
Clean the electronic control unit and its wiring if they are dirty or wet:
1)
Disconnect the plug of the control unit;
2)
Clean with a compressed air jet;
3)
Spray an anti-rust product for electrical contacts.
4)
Take care to apply some silicone (suitable for electric systems) to seal the screws of
the type DIN electric connectors that might have been removed for maintenance
operations.
