In this application, the meter is also set up for aut manual reset at any
time. However, this time, an operator acknowledges the alarm manually while it
still exists. This causes the relay to reset, but the LED stays on until the meter
returns to the normal condition. Remember, for non-latching relays, the LED is
always OFF during normal condition and always ON during alarm condition,
regardless of the state of the relay.
