Alarm 2 Condition
Alarm 2 Condition Indications
When the gas reading reaches the alarm 2 setpoint, the Rig Monitor senses an alarm 2
condition. The Rig Monitor alerts you to an alarm 2 condition as follows:
•
The A2 LED turns on.
•
The gas reading alternates with the ALARM-2 message.
•
The alarm 2 relay energizes.
NOTE:
If the M2 Rig Monitor is in both an alarm 1 and alarm 2 condition, both the A1
and A2 LEDs will be on, the gas reading will alternate with the ALMS 1&2
message, and both alarm relays will energize.
Responding to an Alarm 2 Condition
1.
Follow your established procedure for a high level H
2
S condition.
2.
After the gas reading falls below the alarm 2 setpoint, press the ENTER button to reset
the alarm circuit. Resetting the alarm circuit turns off the A2 light, resets the LCD, and
de-energizes the alarm 2 relay.
NOTE:
If the ENTER button is pressed while the M2 Rig Monitor is in an alarm 2
condition, the A2 LED will flash but all other indications will remain
unchanged.
You cannot de-energize the alarm 2 relay until the gas reading falls below the
alarm 2 setpoint.
