The different alarms are:
Hi Alarm
System goes into alarm if the input value is > Hi Limit + deadband
System goes out of alarm if the input value is < Hi Limit –
deadband
Low Alarm
System goes into alarm if the input value is < Low Limit –
deadband
System goes out of alarm if the input value is > Low Limit +
deadband
ROC Alarm
1. When ROC Mode is set to Off, no ROC alarm test occurs.
2. When ROC Mode is set to Hi, the system goes into alarm if the
change in input value is > ROC Mag + deadband. The system goes
out of alarm when the change in input value is < ROC Mag –
deadband.
3. When ROC Mode is set to Low, the system goes into alarm if
the change in input value is < ROC Mag - deadband. The system
goes out of alarm when the change in input value is > ROC Mag +
deadband.
4. The change in input value is computed in one of two ways,
depending on the state of Fixed Interval. If Fixed Interval is
checked, the change in input is calculated as the absolute value of
the difference between the current value and the last value. If Fixed
Interval is not checked, the change in input is calculated as the
absolute value of the difference between the current value and the
last value that caused a ROC Alarm to occur.
