Chapter 3: Installation & Startup Overview This chapter describes procedures to mount the Beacon 110 Rig Monitor, make wiring connections to the monitor, and start up the monitor. WARNING: Perform all installation and start-up procedures in a “fresh air” environment (environment known to be free of toxic gas, and of normal oxygen content). The Beacon 110 Rig Monitor is not in operation as a gas monitoring system until the start-up procedure is complete.
1. Select the mounting site. When you select the mounting site consider the following factors: • Is a DC power source available? • Is there enough room to open the housing door and make wiring connections through the cable bushings at the bottom of the housing? • Are the display screen and status lights on the Rig Monitor visible? 2. If necessary, close and latch the Rig Monitor housing door. 3. Position the monitor on a vertical surface at eye level (4 1/2 to 5 feet from the floor). 4.
Wiring the Beacon 110 Rig Monitor This section describes procedures to connect external alarm(s) and a recorder to the Rig Monitor. The power, detector, and strobe/horn wiring are all factory wired as shown below.
WARNING: Make all connections to the Beacon 110 Rig Monitor before you plug in or turn on the DC power source. Before you make any wiring adjustments, always verify that all power sources are not live. Connecting DC Power Perform the following functions to connect the Rig Monitor to DC power. One end of the battery cable is already factory wired to the appropriate terminals at the Rig Monitor housing. Use the other end to connect a 12 VDC battery.
Connecting Recorders Perform the following procedure to connect an analog signal recording device to the Rig Monitor. The output at the recorder output terminals is a 4 - 20 mA signal that is proportional to the detection range of the H2S detector head connected to the Rig Monitor’s Fail or Alarm 2 terminals. The Alarm 1 terminals are factory wired and not available for field use. 1. Disconnect the battery clamps from the + and - terminals of the 12 VDC battery. 2.
Start Up Introducing Incoming Power Perform the following procedure to place the Rig Monitor into normal operation. 1. Complete the mounting and wiring procedures described earlier in this chapter. 2. Verify that all wiring connections are correct and secure and that the Rig Monitor’s power switch is in the OFF position. 3. If not already connected, connect the battery clamps to the + and - terminals of the 12 VDC battery. 4. Turn on the power switch. 5.
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.
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).
Alarm Indications NOTE: The Beacon 110 Rig Monitor includes alarm on and alarm off delay settings for alarm 1 and alarm 2. The alarm indications described in this section operate according to the factory set alarm settings. See Table 6 on page 23 for all the factory settings.
Alarm 1 Condition Alarm 1 Condition Indications When the gas reading 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 LED turns on. • The gas reading alternates with the ALARM-1 message. • The buzzer sounds a pulsing tone. • The alarm 1 relay energizes and the strobe/horn activates. Responding to an Alarm 1 Condition 1. Follow your established procedure for a toxic gas condition. 2.
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.
Chapter 5: Configuration Mode Overview This chapter describes how to view and change Beacon 110 Rig Monitor parameters using Configuration Mode. It is accessed using the program buttons. Configuration Mode includes a 5-minute time-out feature. If you do not press a control button for 5 minutes, the Rig Monitor automatically returns to normal operation.
Table 6: Configuration Parameters Parameter (Factory Set Value) Description ALARM-1 (10 ppm) The gas reading at which the Rig Monitor initiates an alarm 1 condition. ALARM-1 (activation) (Increase) Indicates if the alarm 1 circuit is activated by gas readings increasing (Increase) or decreasing (Decrease) to the ALARM-1 Level. • Note: Changing this parameter will affect the operation of the factory installed strobe/horn. Do not change this parameter from the factory setting. ALARM-1 (relay action) (N.
Table 6: Configuration Parameters (Continued) Parameter (Factory Set Value) Description ZeroSupp (2 ppm) The zero suppression feature helps prevent “jumpy” readings near the fresh air reading. For example, if the zero suppression setting for the H2S detector is 2 ppm, the Rig Monitor will display a reading of 0 ppm for gas readings from -2 ppm to 2 ppm. FILTER (5 secs) The filter feature helps “smooth out” jumpy or noisy signals from the detector.
