The button for temporary deactivation of brakes of the trailer or semi-trailer

FHSX18N031
Prior to using the button for temporary deactivation of brakes of the trailer or semi-trailer, it is
always necessary to provide sufficient space in front of the tractor and behind the connected trailer
or semi-trailer where no obstacles or persons will be present for the case that the effect of the
parking braking will not be sufficient and the combination of vehicles moves.
If the trailer is equipped with an electrically operated input, the temporary brake deactivation
button also deactivates the hydraulic brakes of the trailer, semi-trailer. The 3-pin SuperSeal
connector, located behind the console of the 7-pin socket, is used for connection. The signal is
transmitted by the middle pin on the connector.
The button for temporary deactivation of brakes of the trailer or semi-trailer can be used by the operator of
the tractor with the connected trailer or semi-trailer to make sure that the effect of the parking braking system
of the tractor with the connected trailer or semi-trailer when the tractor is braked with the hand brake is
sufficient. If there is a tractor with the connected trailer or semi-trailer which is braked with the hand brake
and the key in the switch box is in the position (I), and we press the button for temporary deactivation of
brakes of the trailer or semi-trailer, the trailer or semi-trailer is deactivated for the time when the button is
pressed (the trailer or semi-trailer does not brake). When the button for temporary deactivation of brakes of
the trailer or semi-trailer is released, the brakes of the trailer or semi-trailer are activated (the trailer or semi-
trailer brakes).
