The fail relay is factory set as normally energized and is not user adjustable.
DC Circuit Protection
Two DC fuses are used in the Rig Monitor. The two fuses are located on the left side of the main
PCB, above the 12 VDC power terminal strip. They cut off the incoming 12 VDC power in the
event of a short circuit or other electrical fault which causes a high curren t draw in the Rig Monitor.
They are housed in vertical fuse holders and are he ld in the holder by a qu arter turn cover. They are
labelled as F1 (left fuse) and F2 (right fuse) on the PCB silk-screen and are rated at 3 A, 250 V.
Power Switch
The power switch is located to the right o f the power s upply and above the relays ( see Figure ). The
power switch turns the incoming 12 VDC power source on and off at the Rig Monitor. When the
switch is up, the power switch is on.
Control PCB
The LCD display and control buttons are located on th e control PCB. It is installed on the main
PCB with three standoffs. The control PCB is connected to the main PCB with the display cable
which is a ribbon cable terminated with 20 position rectangular connectors on each end. The

Chapter 4: Operation
Overview
This chapter describes the Beacon 110 Rig Monitor in normal operation. This chapter also
describes the Rig Monitor in alarm 1, alarm 2, and fail conditions and suggests response to these
conditions.
Normal Operation
Normal operation is defined as follows:
• The start-up procedure is complete.
• The Rig Monitor is not indicating an alarm 1, alarm 2, or fail condition.
• The Rig Monitor is not in Calibration or Configuration Mode.
During normal operation, the Rig Monitor simultaneously displays the current gas reading, unit of
measure, and target gas.
Information Screen
The Information Screen displays the Rig Monitor’s operating voltage and firmware and hardware
information. To display the Information Screen, do the following:
1. Press and hold the DOWN/NO button for 3 seconds. The Information Screen will appear.
2. Continue holding the DOWN/NO button to keep the Information Screen on the display. The
top line indicates the operating voltage that the power converter is providing to the Rig
Monitor. The second line indicates the firmware that is running, version 5.0 in this example,
and the Rig Monitor’s hard ware vers i on , vers ion 2A in this example. This information may be
useful if you need to contact the facto ry with questions about the Rig Monitor.
3. Release the DOWN/NO button when you are done viewing the Information Screen. The
display will return to the normal operation screen within a couple of seconds.
NOTE: The Information Screen is not a good indicator of battery life because the power
converter will operate as normal and have an output of 24 volts until the 12 VDC
battery dies.

4 - 20 mA Signal Output Operation
The output at the 4 - 20 mA output terminals is a 4 - 20 mA signal that is proportional to the
detection range of the Rig Monitor. During normal operation, this signal tracks the gas
concentration on the LCD.
There are several circumstances where the signal output will not track the display reading but will
behave as follows:
• When the Rig Monitor is in its warm-up period, the signal output will be fixed at 4 mA (zero).
• If you e nter Calibration Mode or Configuration Mode, the signal output will be fixed at 3.5 mA
until the Rig Monitor returns to normal operation.
• If the Rig Monitor’s input power decreases below 10 volts so that the Rig Monitor is in a low
power alarm, the signal output is fixed below 2.4 mA until the low power alarm is cleared.
NOTE: Under typical operating conditions, there will be no low power alarm. The 12 VDC
battery that is recommended for operation will die before the power converter
recognizes a low power condition.
• If the R ig Monitor goes into a fail condition, after a 30 second delay, the signal output is fixed
below 2.4 mA until the fail alarm is cleared. During the 30 second delay, the output follows the
detector output. In the case of a downscale reading, the displayed gas reading will only go as
low as -10% of full scale but the signal output will continue to track the reading even if it’s
lower than -10% of full scale.
Viewing and Resetting Min/Max
Readings
The reset switch may be used to view and reset the minimum and maximum gas readings.
NOTE: Minimum and maximum readings are reset if the instrument is turned off.
1. While the Rig Monitor is in normal operation, press and hold the reset switch button for 5
seconds.
2. The display will indicate the minimum reading on the bottom display line and the maximum
reading on the top display line for about 3 seconds before indicating <RESET> TO CLEAR.
3. To return to normal operation without resetting the minimum and maximum readi ngs, do not
press the reset switch button and allow the unit to return to normal operation. It will return to
normal operation in about 5 seconds.
To reset the min imu m and max imu m r eadi n gs, p r ess and hol d the r es et s wit ch butt on
while the <RESET> TO CLEAR message is on the display until the dis p lay indicates
Min/MAX Is RESET. Release the reset switch button.The unit will then return to
normal operation in about 5 seconds.

until the gas reading falls below the alarm 1 setpoint.
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 foll ows:
• The alarm 2 LED turns on.
• The gas reading alternates with the ALARM-2 message.
• The buzzer sounds a pulsing tone.
• The alarm 2 relay energizes and the strobe/horn will remain activated.
NOTE: If the Beacon 110 Rig Monitor is in both an alarm 1 and alarm 2 condition, both the
alarm 1 and alarm 2 LEDs will be on, the gas reading will alternate with the ALMS
1&2 message, and both alarm relays will energize.
Beacon 110 Rig Monitor Operator’s Manual 20
Responding to an Alarm 2 Condition
1. Follow your establ ished procedure for a toxic gas condition.
2. The alarms are factory set as latching. After the gas reading falls below the alarm 2 setpoint,
press the reset switch to reset the alarm circuit. Resetting the alarm circuit silences the buzzer,

Chapter 6: Maintenance
Overview
This chapter describes how to calibrate the Beacon 110 Rig Monitor using Calibration Mode,
replace the DC fuses, and preventive maintenance procedures for the Rig Monitor. It includes a
troubleshooting guide for problems you may encounter with the Rig Monitor.
Calibration Frequency
Although there is no particular calibration frequency that is correct for all applications, a calibration
frequency of every 3 to 6 months is adequate for most Rig Monitor applications. Unless experience
in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration
frequency of every 3 months.
If an application is not very demanding, for example detection in a clean, temperature controlled
environment where hydrogen sulfide is not normally present, and calibration adjustments are
minimal at calibration, then a calibration frequency of every 6 months may be adequate.
If an application is very demanding, for example if hydrogen sulfide is present often and in
significant concentrations or the environment is not well controlled, then more frequent calibration
than every 3 months may be necessary.
Calibration Mode
Calibration Mode is used to calibrate the Rig Monitor’s detector head. All calibration adjustments
are made at the Rig Monitor housing after calibration gas is applied to the detector.
Calibration Gas Response Memory Feature
The Rig Monitor has the capability to “remember” the detector’s response to the calibration gas
after the gas is remove d from the detector during the fresh air or span adjustment procedure. This
feature enables one person to perform calibration if the detector is mounted remotely from the Rig
Monitor. When zero air is applied to the Rig Monitor during a fresh air adjustment, the Rig Monitor
will freeze the display reading at the lowest response and the Rig Monitor will continue to display
this reading and retain it in its memory until the fresh air adjustment procedure is completed. When
calibration gas is applied to the Rig Monitor during a span adjustment, the Rig Monitor will freeze
the display reading at the highest response to the calibration gas. The calibration gas can then be
removed and the Rig Monitor will continue to display this reading and retain it in its memory until
the span adjustment procedure is completed.
25 Beacon 110 Rig Monitor Operator’s Manual
Calibration Program Flow
Figure 10 below illustrates the general flow of the Calibration Program fo r a direct connect
detector. See the next section, “Preparing for Calibration”, for instructions to enter Calibration
Mode. In general, if a question mark, “?”, is part of the display text, use the UP/YES or DOWN/NO
button to respond. Use the UP/YES and DOWN/NO buttons to increase or decrease a displayed gas
reading when performing a span (zero for oxygen) operation, and use the ENTER button to accept

Preventive Maintenance
This section describes a preventive maintenance s chedule to ensure the optimum performance of
the H
S detector. It includes daily, monthly, and quarterly procedures.
2
Daily
Verify a display reading of 0 P P M H2S at the controller. Investigate significant changes in the
display reading.
Monthly
This procedure describes a test to verify that the H2S detector responds properly to hydrogen
sulfide. It describes a test using a fixed flow regulator with an on/off knob. RKI Instruments, Inc.
recommends using a 0. 5 LPM (liters per minute) fixed fl ow regulator.
NOTE: Performing a response test on the H2S detector may cause alarms. Be sure to put the Rig
Monitor into its calibration program or disable external alarms before performing this
test.
Preparing for the response test
1. While in normal operation, press and hold the UP/YES button for 5 seconds and press the UP/
YES button again when asked if you would like to enter Calibration Mode.
2. Verify that the R ig Mon itor display reading is 0.
If the display reading is not zero, set the zero reading of the detector as described in
the Start Up section of this manual, then continue this procedure.
3. Screw the regulator into the calibra tion cylinder.
4. Use the calibration kit sample tubing to connect the regulator to the calibration cup/splash
guard.
Performing the response test
1. Turn the regulator’s on/off knob counterclockwise to open the regulator. Gas will begin to
flow.
2. Allow the gas to flow for two minutes, then verif y that the reading is within ± 20% of the
cylinder gas concentration.
NOTE: If the reading is not within ± 20% of the correct response reading, calibrate the detector
as described in the Calibration section of this manual.
3. Turn the regulator’s on/off knob clockwise to close the regulator.
4. Unscrew the regulator from the calibratio n cylinder.
5. When the Rig Monitor display readin g falls below the alarm setpoints, return it to normal
operation.
6. Store the components of the calibration kit in a safe place.
Quarterly
Calibrate the H2S detector as described in the Calibration section of this manual.
