Alarm Output (ALARM)
Alarm outputs may be assigned to: Modbus PV or math channel (PV NUM); rate (RATE); total
(TOTAL); grand total (GRTOT); always on (ON), or always off (OFF).
Alarm outputs may be assigned to rate, total, or grand total; or be forced on or off.
Modbus PV or Math Alarm (PV NUM)
Program a PV (PV1-16) or math channel (CV1-4) to trigger an alarm. Select the source
PV or CV for the alarm and enter the display value set and reset points. The 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.
