Beacon 200 Rig Monitor Operator’s Manual • 26
• The display reading is -10% of full scale or lower.
• The Rig Monitor or detector head is malfunctioning.
When the Rig Monitor senses a fail condition, it alerts you as follows:
• The FAIL light turns on.
• The gas reading for the failing channel is replaced by the FAIL
message.
• The buzzer sounds a steady tone.
• The common fail relay de-energizes.
NOTE: If you elected to use the channel’s alarm 2 relay as an individual
fail relay in the Channel Control & Setup menu, the relay de-
energizes in a fail condition. See “Chapter 5: Channel Control and
Setup Program” on page 28 for a description of this setting.
Responding to a Fail Condition
This section suggests response to a fail condition.
1. Verify that the detector head wiring to the Rig Monitor is correctly and
securely connected.
2. Verify that the detector head’s detector is correctly and securely
connected.
3. See the troubleshooting guide in the detector head instruction manual.
Low Battery Condition
The 12 VDC battery that is recommended for operation of the Rig Monitor
is typically dead before the power converter recognizes a low power
condition. As a result, when the Rig Monitor is used with a 12 VDC battery,
there may be no low power alarm and the unit will instead shut off once the
battery is dead.
