In this application, the meter is set up for manual reset only after the signal
passes the reset point (alarm condition has cleared). Acknowledging the alarm
while it is acknowledged after it returns to the normal state, the LED and the relay
go off. Notice that the LED remains on, even after the meter returns to the normal
condition. This is because, for latching relays, the alarm LED reflects the status of
the relay, regardless of the alarm condition.
Acknowledging Relays
Acknowledge relays programmed for manual reset via the programmable front
panel function keys F1-F3 (Default: F3 assigned to ACK).
