Pixsys ATR 401 - Selection of Process Value Related to the Command Output and to the Alarms; Remote Setpoint by Analogue Input

18 ATR401 - User manual
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;
•
 : Di erence between inputs: AI1-AI2;
• : Di 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, di erence and addition are available only if both inputs are
con 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  on par. 20  
