For the workshop
Perform the following preparatory work:
•
Connect ammeter,
Remove fuse F043 and connect meter (measurement range at least 3A) between the
contacts.
•
Connect voltmeter,
Connect actuator adapter cable (X899.980.246.207, 8-pin) to actuator connection.
Connect meter to Pin 4 (+UB of fuse F043) and Pin 8 (earth).
•
You should be able to read the two meters at the same time. If you do not have two
meters, measure the current and voltage in succession.
•
Connect PC and in the Gearbox menu, select diagnosis window Gearbox Adjustment.
When the fault occurs, you can determine the adjustment angle.
•
Start engine.
•
Select neutral on gearbox.
•
Adjust range selection (adjustment code 4003).
If picture A00437 is output, press neutral button.
•
Select acceleration ‘Ramp’ I and set minimum acceleration
(0.02 or 0.03 km/h) (see Operating Instructions Favorit 700 Chapter 7.3).
This adjustment then causes the actuator to move through its range in the smallest
possible steps. Engine speed approx. 1400 rpm.
•
Release hand brake (chock tractor wheels).
Press neutral button.
Press Activation button, push drive lever forwards and hold. The gearbox ratio is adjusted
in the forward direction until the maximum setting is reached (takes around 7 minutes) or a
fault occurs.
The gearbox adjustment can be monitored on the terminal. During the adjustment
process, the current consumption (heavily temperature-dependent) in good condition is up
to approx. 100 mA +/- 50 mA. Beware, meter display will jump.
