J4
Connector for light lamp connection 230 V / max. 100 W ( fig. 4).
The lamp lights when the unit has performed any first action (control button is
pressed, door position sensor is activated) and goes out when the power is turned
off. If faults in the platform operation are detected, the lamp no longer lights
(section 7 ‘Faults and recommendations on their elimination’)
J5
Connector for connection of the electric motor of hydraulic unit ( fig. 5) and
STOP
safety
sensor ( NC ).
CAUTION! While opening the 24 V at J5 connector, control voltage of
24 V DC turns off and control unit does not operate. For control unit
operation, OUT + 24 V and IN + 24 V contacts should be closed ( NC )

Connector for connection of hydraulic unit valves ( fig. 6) and door position sensor ( fig. 8).
If the sensor is triggered, the electric motor of hydraulic unit turns off and the dock
leveller starts lowering
J9
Connector for connection of the jumper to select an output type of door position sensor:
PNP
or
NPN
(terminal output)
J10 Connector for connection of control buttons 2 and 3 , LED 4 ( fig. 1, fig. 7)
J12
The jumper for setting the overcurrent protection in the electric motor of hydraulic
unit. In the case of overcurrent or fault ( section 7 ‘Faults and recommendations on their
elimination’), the dock leveller movement completely stops ( STOP ).
CAUTION!
If the jumper is not set, the protection will be turned off
J13

ATTENTION!
The position of the jumper set in J12 and J13 connectors is saved when the
on-off switch 1 ( fig. 1) is switched from ‘ 0 ’ position (‘ Off ’ position) to ‘ I ’ position (‘ On ’ position)
and maintained during the control unit operation. If the jumper position in J12 and J13
connectors is required to be changed, power off the unit, set the jumper in the appropriate
position and power on the unit.
