7.1
Selection of process value related to the command
output and to the alarms
When second input is enabled (par.11

other than

) it is possible to
choose the process value to be related to command output, to alarms and to
retransmission. Following options are available:
•

: Value read by input AI1;
•

: Value read by input AI2;
•

: Mean between inputs AI1 and AI2;
•

: Diff erence between inputs: AI1-AI2;
•

: Diff erence between inputs as absolute value: AI1-AI2;
•

: Addition between inputs: AI1+AI2.
• Process related to command output must be set on parameter 19

• Process related to alarms must be set on par. 38

for alarm 1, on par. 47

for alarm 2, on par. 56

for alarm 3 and on par. 65

for alarm 4.
• Value to retransmit must be set on par. 88

It is possible to choose the visualization for display 2 on parameter 86

.
Mean, diff erence and addition are available only if both inputs are
confi gured either for temperature sensors or for linear signals V / mA.
7.2
Remote setpoint by analogue input
It is possible to enable remote setpoint function setting
