● Installation of CS 31 system

Generalities

Some installation rules have to be respected. These rules concern the ground concept, the connection of the CS 31 bus and the different power supplies installations. The following main principles must be applied :

Each type of signal has to be mounted separatly

– power supply 230 VAC

– analogue and low voltage signals

The ground and power supply wires must be connected in star

● Refer to the description of each remote unit for connection of inputs and outputs.

● Installation of the bus

The CS 31 bus is a RS 485 serial line and a schield twisted pair.

The CS 31 bus is a master slave bus. Only one master can be present on the bus.

The maximum length between the both extremities is 500 metres.

The master should be :

– a central unit : 07 KR 31, 07 KT 31, 07 KR 91,07 KT 92, 07 KT 93, PCZB, UCZA/UCZB

– a PLC coupler : 07 CS 61 and 07 CS 91 for the ABBProcontic T 200 and T 300

– a PC board : 07 CM 90

● Characteristics of the bus' cable The CS 31 bus is a shield twisted pair RS 485

– cross 0.22 ... 0.8 mm2

– twists > 10 per metre

– resistance – impedance 100/km

– characteristics 100 to 150 

– capacitance

– schield < 150 nF/km

– termination 120 , 1/4 Watt resistor

connected at the ends of the bus

– ALCATEL MCX-T

– DRAKKA dracoda 2903
