5.2.6 Voltage
supply
The supply cable for the voltage supply should be kept as short as possible. For cable lengths up
to 20 m the cable should have 2×0.5 mm
2
, for larger lengths the cross section of the cable needs to
be accordingly increased. For power consumption of the system please refer to section “technical
data”.
Attention
The positive supply v24 VDC should not be
connected to machine ground.

Sensor connection (connections S1–4 and E1–4)
The sensor cable SCI20-S is connected at the control unit by plug.
Because of the special wiring of the sensor cable SCI20S it is no longer necessary to avoid mixing
transmitter and receiver cable. When using the SCI20S cable the transmitting sensor and the
receiving sensor will automatically be connected to the appropriate sockets of the control unit.
Note
The sensor cable is an active part of the sensor. The performance
data is therefore based on the compliance with cable specification.
