menu. The following sections describe the default setting for the
channel relays which is NDE.
Common alarm 1 and alarm 2 relays are factory-set as NDE, and
the common fail relay is factory set as NE. The common relays’
NE/NDE settings are not user-adjustable.
Alarm 1 Condition
This section describes the audible and visual indications for an alarm 1
condition and suggests response to an alarm 1 condition.
Alarm 1 Condition Indications
When the gas reading of an active channel reaches the alarm 1 setpoint,
the Rig Monitor senses an alarm 1 condition. The Rig Monitor alerts you to
an alarm 1 condition as follows:
• The ALARM 1 light turns on.
• The gas reading in alarm 1 condition flashes and alternates with the
ALARM-1 message.
• The buzzer sounds a Pulsing tone.
• The common alarm 1 relay energizes and the strobe/horn activates.
• The applicable alarm 1 channel relay energizes.
Responding to an Alarm 1 Condition
This section suggests response to an alarm 1 condition.
1. Follow your established procedure for a low level H
2
S condition.
2. Alarms are latching. After the gas reading falls below the alarm 1
setpoint, press the reset switch to reset the alarm 1 circuit. Resetting
the alarm 1 circuit silences the buzzer, turns off the ALARM 1 light,
resets the channel display, de-energizes the common and channel
alarm 1 relays, and turns off the strobe/horn.
NOTE: To silence the buzzer while in an alarm 1 condition, press the
reset switch.
You cannot de-energize the alarm 1 relays and consequently the
strobe/horn until the gas reading falls below the alarm 1 setpoint.
