Beacon 110 Rig Monitor Operator’s Manual
Alarm Indications
NOTE:
The Beacon 110 Rig Monitor includes alarm on and alarm off delay settings for alarm 1
and alarm 2. The alarm indications described in this section operate according to the
factory set alarm settings. See Table 6 on page 23 for all the factory settings.
NOTE:
You can select normally energized (N. EN) or normally de-energized (N. DE-EN)
alarm 1 and alarm 2 relay action settings in Configuration Mode. The following
sections describe the standard factory setting for these relays which is N. DE-EN.
The fail relay is set as normally energized in the firmware and is not user-adjustable.
CAUTION:
Changing the relay action setting for the Alarm 1 relay in Configuration Mode will
cause the strobe/horn to be on during normal operation.
