Wiring
Bus cable
Note that screened multi-core twisted-pair control cable is required as bus line, e.g.
UNITRONIC
®
BUS CAN 2x 2x...mm² or RE-2YCYV-fl 2x2x...mm².
The baud rate (data transfer rate) dictates the cable length between the bus nodes, and
the conductor size dictates the total power consumption of the sensor.
The baud rate is set via code switches (S8 to S10). Default factory setting of control
unit LRR 1-40: baud rate 250kbit /s (cable length 125m).
For longer cable lengths reduce baud rate accordingly. Make sure that all bus nodes
feature the same settings.
