Process alarms
Process Alarm detection is based on the OUT value. Configure the alarm limits of the
following standard alarms:
•
High (HI_LIM)
•
High high (HI_HI_LIM)
•
Low (LO_LIM)
•
Low low (LO_LO_LIM)
To avoid alarm chattering when the variable is oscillating around the alarm limit, an alarm
hysteresis in percent of the PV span can be set using the ALARM_HYS parameter.
The priority of each alarm is set in the following parameters:
•
HI_PRI
•
HI_HI_PRI
•
LO_PRI
•
LO_LO_PRI
