Wiring
Bus cable
Use screened multi-core twisted-pair control cable – e.g. UNITRONIC ® BUS CAN x x...mm or
RE-YCYV-fl x x...mm as bus cable or the preassembled control cable that is available as
accessory.
The baud rate (data transfer rate) dictates the cable length between the bus nodes, and the total power
consumption of the sensor dictates the conductor size.
The baud rate is set via code switches 3 (S8 to S0), Fig. 6. Default factory setting of conductivity
electrode LRG x- 40: baud rate 50 kbit/s (cable length 5 m).
For longer cable lengths reduce baud rate accordingly. Make sure that all bus nodes feature the same
settings.

Note
The max. baud rates and cable lengths indicated above are based on empirical values
obtained by GESTRA. In certain cases it may be necessary to reduce the baud rate in
order to ensure operational safety.
The design and preparation of the data cable is an important factor for the electro-
magnetic compatibility (EMC) of the equipment. Wiring should therefore be carried out
with special care.
If you do not use the preassembled control cable, connect the connector and the jack for the CAN bus
lines according to the wiring diagram.
