External Description

This section describes the housing and all external components of the Beacon 110 Rig

Monitor. For the purposes of this description, the housing door is considered the front of the monitor.

Housing

The Rig Monitor’s fiberglass housing is weather- and corrosion-resistant. It is suitable for installation where general purpose equipment is in use. The housing door is hinged on the left side and is secured by two latches on the right side. The display screen and status lights are visible through a window in the housing door. Four mounting feet are attached to the back of the housing (one at each corner). The mounting feet allow installation to a vertical surface. Two cable bushings on the bottom of the housing are for wiring connections. One cable bushing is for the 12 VDC battery connection. The other is for the direct connect H

2

S detector connection. Both are factory wired.

Buzzer

The buzzer is on the bottom center of the housing in front of the reset switch. The buzzer sounds audible alarms to warn you of gas alarms and instrument failures.

Reset Switch

The reset switch is on the bottom of the housing behind the buzzer. The reset switch serves four functions:

• You can reset the alarm circuits for “latched” alarms after an alarm 1 or alarm 2 condition passes.

• You can silence the buzzer during an alarm 1 or an alarm 2 condition. You cannot silence a fail condition.

• You can turn off the strobe/horn in an alarm 1 condition once the condition has passed.

• You can display and reset the minimum and maximum readings that the Rig Monitor has experienced since the last min/max reset or startup.

Alarm Strobe/Horn

The Rig Monitor has a red alarm strobe light/horn installed on the top of the housing. The

Rig Monitor retains its NEMA 4X rating with the strobe installed. Strobe/horn operation is controlled by the Alarm 1 relay contacts. The relay action settings can be changed in

Configuration Mode.

Internal Description

This section describes the internal components of the Beacon 110 Rig Monitor

Power Converter

The power converter is located underneath the control PCB. It takes 12 VDC voltage supplied to the Rig Monitor and converts it to 24 VDC which is used to run the Rig

Monitor.

Main Printed Circuit Board (PCB)

The main PCB is mounted inside the housing. The main PCB includes the terminal strips, relays, fuses, and power switch.

Terminal Strips

The Rig Monitor includes terminal strips for field and factory wiring connections. See

“Wiring the Beacon 110 Rig Monitor” on page 13 for detailed wiring procedures.

12 VDC In Terminal Strip.

The 12 VDC In terminal strip is a 3-point terminal strip located in the lower left corner of the main PCB. It facilitates wiring from a 12 VDC battery with the factory supplied battery cable. Table 2 lists the function of each terminal.

Detector/Transmitter Terminal Strips.

Three adjacent terminal strips are located along the right side of the main circuit board above the controller terminal strip (see

Figure ). These three terminal strips labelled LEL, Oxy, and AMP facilitate wiring connections to a detector or a 4 - 20 mA transmitter. The Beacon 110 Rig Monitor only uses the top terminal strip, labelled AMP, for wiring to the H

2

S detector. The LEL and

Oxy

terminal strips are not used.

Ground Stud

The threaded ground stud is used for making connections to earth ground. It is connected through the main PCB to the (earth) terminal on the 12 VDC In terminal strip. A kep nut on the stud may be removed for installation of one or more lugs to make wiring connections. The detector cable shield’s drain wire is connected to the stud.

Relays

The Rig Monitor includes three alarm relays located above the alarm terminal strip. They are from left to right Fail, Alarm 1, and Alarm 2. The relays are form C, single-pole, double-throw (SPDT) and rated for 10 amps at 250 VAC (resistive). The Rig Monitor uses the Alarm 1 relay to control the factory installed strobe/horn. Only the Fail and Alarm 2 relays are available for customer use.

NOTE:

You can select normally energized (N.EN) or normally de-energized (N.DE-

EN) settings for the alarm 1 and alarm 2 relays. See “Chapter 5: Configuration

Mode” on page 22.

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 current draw in the Rig Monitor. They are housed in vertical fuse holders and are held in the holder by a quarter 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 of the power supply 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 the 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 display cable connects to the control PCB on the back of the top edge and to the main PCB directly below the control PCB.

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.

H2S

0 ppm

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.

24.2V v5.0 2A

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 hardware version, version 2A in this example. This information may be useful if you need to contact the factory 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.

17 Beacon 110 Rig Monitor Operator’s Manual

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 enter 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 Rig Monitor goes into a fail condition, the signal output is fixed below 2.4 mA until the fail alarm is cleared.

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 readings, 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 minimum and maximum readings, press and hold the reset switch button while the <RESET> TO CLEAR message is on the display until the display indicates

If the reset switch is pressed while the Beacon 110 Rig Monitor is in an alarm 1 condition, the buzzer will be silenced and the alarm 1 LED will flash.

You cannot de-energize the alarm 1 relay and consequently turn off the strobe/ horn 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 follows:

• 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.

Responding to an Alarm 2 Condition

1.

Follow your established 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, turns off the Alarm 2 LED, returns the LCD to the normal operation screen, and de-energizes the alarm 2 relay.

21

NOTE:

If the reset switch is pressed while the Rig Monitor is in an alarm 2 condition, the buzzer will be silenced and the alarm 2 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.

Fail Condition

Fail Condition Indications

The Rig Monitor indicates a fail condition for any of the following:

• The detector head wiring is disconnected or incorrectly connected.

• The display reading is -10% of full scale or lower.

When the Rig Monitor senses a fail condition, it alerts you as follows:

• The fail LED turns on.

• The gas reading is replaced by the FAIL message.

• The buzzer sounds a steady tone.

• The fail relay de-energizes.

Responding to a Fail Condition

NOTE:

A fail condition cannot be reset using the reset switch.

1.

Verify that the detector head wiring is correctly and securely connected.

2.

Verify that the replaceable plug-in sensor is properly installed.

3.

If necessary set the zero reading for your detector head as described in “Calibration

Mode” on page 25.

Low Power 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.

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 removed 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.

Calibration Program Flow

Figure 10 below illustrates the general flow of the Calibration Program for 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

Frequently Answers and Questions

What is the Beacon 110 Rig Monitor used for?
It is a fixed mount, hydrogen sulfide monitoring controller designed for use at oil drilling sites.
What does the Beacon 110 Rig Monitor display?
It displays the current gas reading on an LCD display.
What are the alarm indications on the Beacon 110 Rig Monitor?
The Rig Monitor includes audible and visual alarms that warn you of hazardous gas conditions. There are three types of alarms: Alarm 1, Alarm 2, and Fail. The alarm circuit includes two levels of gas alarms. The fail circuit alerts you to failures in the gas detector head or controller. The Rig Monitor provides a 4 - 20 mA signal proportional to the target gas reading for use by a recording device. Two sets of relay contacts, one controlled by Alarm 2 and one by the fail alarm, rated at 10 amps 115 VAC, 10 amps 220 VAC, and 10 amps 30 VDC are available for controlling devices such as lights or horns or for controlling higher rated relays. The alarm 1 relay is factory wired to the strobe/horn.
How do I change the Beacon 110 Rig Monitor settings?
You can change the Beacon 110 Rig Monitor settings using Calibration and Configuration Modes.
How often should I calibrate the Beacon 110 Rig Monitor?
The frequency of calibration depends upon the type of use you have and the sensor types. Typical calibration frequencies for most applications are between 3 and 6 months, but can be required more often or less often based on your usage.
