RKI Instruments Beacon 200 Rig Monitor, LEL/H2S - Manual (Page 52)

47 • Beacon 200 Rig Monitor Operator’s Manual
Buzzer Not
Working • The buzzer does not
sound an audible
alarm during alarm
conditions.
• The buzzer sounds
weak or broken.
• The buzzer is
disconnected or
misconnected.
• The buzzer is
malfunctioning.
1. Verify that the wiring to the BUZ- and
BUZ+ terminals of the controller terminal
strip is correct and secure.
2. If the buzzer difficulties continue, contact
RKI for further instruction.
Reset Switch
Not Working • The buzzer does not
silence when you
press the reset switch.
• The applicable alarm
circuit does not reset
when you press the
reset switch after an
alarm condition
passes.
• The reset switch is
disconnected or
misconnected.
• The reset switch is
malfunctioning.
1. Verify that the wiring to the RESET (2)
terminals of the controller terminal strip is
correct and secure.
2. If the reset switch difficulties continue,
contact RKI for further instruction.
Strobe/Horn
Not Working • The strobe/horn does
not activate when an
alarm 1 condition
occurs. • The strobe/horn is
malfunctioning.
• The strobe/horn wiring is
disconnected or
misconnected.
1. Verify that the strobe/horn is wired
properly to the alarm terminal strip.
2. If the strobe/horn difficulties continue,
contact RKI for further instruction.
Fail Condition • Rig Monitor indicates a
fail condition.
• Controller indicates a
fail condition.
• The detector wiring to
the main PCB is
disconnected or
misconnected.
• The plug-in H
2
S sensor
is not properly plugged
into the sockets in the
detector housing body.
• The detector fresh air
signal is low enough to
cause a fail condition.
• The detector is
malfunctioning.
• The main or display PCB
is malfunctioning.
1. Verify that the detector wiring is correct
and secure.
2. Confirm that the plug-in H
2
S sensor is
installed properly.
3. Calibrate the Rig Monitor.
4. If the fail condition continues, replace the
detector.
5. If the fail condition continues, contact RKI
for further instruction.
Slow or No
Response/
Difficult or
Unable to
Calibrate • Rig Monitor responds
slowly or does not
respond to response
test.
• Unable to successfully
set the fresh air or
span reading during
calibration.
• Rig Monitor requires
frequent calibration.
Note: Under “normal”
circumstances, the
detector requires
calibration once every 3
months.
Some applications may
require a more frequent
calibration schedule.
• The calibration cylinder
is low, out-dated, or
defective.
• The flame arrestor in the
H
2
S detector housing
cap or the LEL flame
arrestor is wet or
clogged with dirt or other
particulates.
• The detector is
malfunctioning.
• The main PCB is
malfunctioning.
1. Verify that the calibration cylinder contains
an adequate supply of a fresh test sample.
2. Verify that the calibration gas
concentration is appropriate for the
detector. Zero emission air (0 %LEL and 0
ppm H
2
S) is normally used for a zero
adjustment if the environment is suspect
and 50% LEL and 25 PPM H
2
S in nitrogen
is normally used for a response
adjustment.
3. Check the H
2
S detector housing cap and
the LEL detector to determine if the flame
arrestor is wet or dirty. Clean if necessary.
4. If the calibration/response difficulties
continue, replace the detector.
5. If the calibration/response difficulties
continue, contact RKI for further
instruction.
