3.1.3 Description of the features of the connectors and signals.
The CS-I / T interfaces to the CS-I / P through the supplied 9-pin plug-socket RS422
cable. Male connector is on the CS-I / P c RS422 female on CS-I / T. The input signals and
inlets on the CS-I / P are underneath explained:
X1 CAN BUS (5 pin M)
X2 Proportional Valve (4 pin M)
X3 Measuring inputs (6 pin M)
IN1 Control signals (12 pin M)
IN2 Signals of program selection, control and protection (12 pin M)
OUT1 Drive signals for solenoid valves and alerts (10 pin M)
OUT2 Alert signals (9 pin M)
RS422 Communication line with CS-I/T (9 pin male tank)
RS232/RS485 Communication line and programming (9 pin male tank)
M = Male footprint 2.5 Phoenix type
The input signals are activated at +24VP
The disposal of hardware signals is given in Annex A
