Installation Connecting connection cable ATTENTION! The safety information set out in section 2.2 must be observed to prevent damaging the vehicle's electrical system. Connect the plug (2) to the display. Route the power supply connection (8) to the point approved by the vehicle manufacturer and connected there (see con- nection diagram in section 4.1). -
Page 11: Operation
Operation ADVICE! The figures partially show sensor couplings with 2 or 3 sensors, however, descriptions apply to both versions. Self-diagnostic Operating indicator (fifth wheel coupling open/ ready for coupling) The sensor coupling carries out a self-diagnostic test when the igni- tion is switched on. -
Page 12: Operating Indicator (Faults)
The red "Fifth wheel coupling A system error has occurred. closed" indicator will flash and an alarm will sound. The JOST fifth wheel coupling is not correctly locked, i.e. the fifth-wheel coupling is closed, but the king pin is not engaged or not detected by the system. -
Page 13: Sensor Coupling Process
Operation Sensor coupling process The fifth wheel coupling is open and ready to cou- ple. JSKC/38 Drive the tractor unit under the semi-trailer. Raise the fifth wheel using the air suspension until the fifth wheel coupling plate contacts the skid plate. For a sensor coupling with skid plate detection (3 sensors), the display now switches on automatically. - Page 14 Operation Reverse the tractor unit until the fifth wheel cou- pling closes. The green "Fifth wheel coupling closed" display will be lit. The fifth wheel coupling is correctly closed. ADVICE! The display will go dark after 2 minutes. WARNING! The driver must check that the semi-trailer has been connected properly.

After a time limit of 2 minutes has elapsed the alarm will stop and the red LEDs will be constantly lit until the tractor unit has been driven out. - Page 16 Operation Drive out the tractor unit as usual, lowering the air suspension. The red indicators go out. ADVICE! The display will switch off completely after approx. 10 seconds. MUB 007 001 M01 (REV-C) 07/2020 Sensor JSK...
