Optional changeover to 20 A
By default, the electric landing gear is preset to a maximum motor
current of 15 A.
However, it is possible to operate the system with a higher motor
current in 20 A mode. 20 A mode is only allowed to be activated if
the feeder cable from the semi-trailer tractor to the semi-trailer is
fused with at least 20 A, and the cables are designed for operation
at 20 A. Information about this can be obtained from the manu-
facturer of your semi-trailer tractor or semi-trailer. Proceed as fol-
lows to do this:
Activate the system by pressing both control elements simul-
taneously for five seconds. Both control elements flash alter-
nately if the control unit has been activated in 20 A mode.
From this point on, proceed as described in the previous sec-
tion for automatic or momentary-contact mode.
If exclusively semi-trailer tractors with feeder cable fusing of at
least 20 A are used, the control can be set to operate in 20 A mode
permanently by making a setting on the electronic circuit board.
ADVICE!
This work is exclusively allowed to be carried out by spe-
cialist personnel, otherwise there is a danger of damage
to the electronic circuit board, e.g. by electrostatic dis-
charge.
Proceed as follows to do this:
Disconnect the motor from the electrical power supply.
Unscrew the motor housing bolts (10 x T20).
