2.3.1 SEAT SWITCH
Method of operation to series 6/95:
A seat switch is installed in the driver’s seat, which activates timer 1A3 when actuated. In order to prevent
a faulty operation of the switch on uneven roadways, the timer cuts off the enable signal for the traction and
lift control after a delay of approx. 2 seconds when the seat switch is no longer actuated.
Timer 1A3 is mounted opposite the voltage converter on the contactor board. The timer is connected to the
main cable harness via a 8-pin connector.
Method of operation from series 7/95:
The timer 1A3 has been omitted on trucks built since 7/95. The travel control time delay is integrated into
the electronic travel unit 1A2. Starting with this series, the working hydraulics can be operated without the
seat switch having to be activated.
