The control’s sensor inputs can be freely
parametrised. The inputs are not defined for a
particular sensor type.
When commissioning a sensor, the sensor
input on the control must be activated and
the sensor type specified

and maintenance instructions. If the RLS 1 WR
on the controller is deactivated (parameter for
simple control unit inactive), up to 4 sensors
can be connected.
The power supply to
sensors 3 + 4 can be ensured via terminals
LD1, LD2, LD3 (all 12 VDC) or with double
assignment, via the 24 VDC supply of sensor
connections.
