Alarm Output (alrm)
Alarm outputs may be assigned to rate, total, or grand total; or be forced on or off.
Rate Alarm (rate)
Program the rate set point to trigger the alarm. Rate alarm deadband is determined
by the difference between set and reset points. Minimum deadband is one display
count. If set and reset points are programmed the same, output will reset one count
below set point.
Total or Grand Total Alarm (Total, Grtot)
Program total or grand total set point. A pulse alarm will generate when the set value
is reached by the total or grand total.
If the total/grand total is set for manual reset, this alarm will remain until the to-
tal/grand total is reset to 0.
