there is enough room to perform a calibration. A cover on the front of the junction box allows access to the interior of the junction box. The detector housing body protects the sensing components within the housing body. Use the removable cap near the bottom of the housing body to access the sensor for maintenance or replacement. The cap protects the sensor from damage and includes a flame arrestor which contains any sparks which may occur within the detector housing body.
Internal Description This section describes the internal components of the Rig Monitor. Display Printed Circuit Board (PCB) The display PCB is mounted to the power supply mounting plate which is in turn mounted to the main PCB. The power supply mounting plate and main PCB are described below. The display PCB includes the display, the status lights, and the program buttons.
Status Lights The Rig Monitor includes four status lights that indicate the current status of the monitor. The status lights are to the left and right of the display (see Figure 4). • Pilot Light. The pilot light is on when the Rig Monitor is receiving incoming power. • Fail Light. The fail light turns on when the Rig Monitor is experiencing a fail condition. A fail condition can be caused by a failure within the Rig Monitor or detector head(s) wired to the Rig Monitor.
Main PCB The main PCB is mounted inside the housing. The power supply mounting plate is mounted to the main PCB with four standoffs and the display PCB is mounted to the power supply mounting plate with four standoffs. The main PCB includes the terminal strips, relays, fuses, and power switch. Terminal Strips The Rig Monitor includes four terminal strips for external wiring connections. See “Wiring the Beacon 200 Rig Monitor” on page 16 for detailed wiring procedures.
• DC In Terminal Strip. The DC in terminal strip is a 3-point terminal strip located above the controller terminal strip (see Figure 1). It facilitates wiring from the 12 VDC battery. The 50 foot battery cable is factory wired to this terminal strip. Table 4 lists the function of each terminal.
NOTE: The alarm 2 channel relays may be set to operate as individual channel fail relays. See “Configure Channel Settings Menu” on page 29 for instructions. • Common relays. The three common relays, alarm 1, alarm 2, and fail, are to the left of the controller terminal strip (see Figure 1). These relays are common for both channels. For example, the alarm 1 common relay energizes if either channel 1 or channel 2 recognizes an alarm 1 condition.

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 running the Channel Control & Setup or Calibration Programs.
Recorder Output Operation The output at the recorder output terminals is a 4 - 20 mA signal for each active channel that is proportional to the detection range of the channel. A channel that is set as CHANNEL NOT USED or CHANNEL DISABLED in the Channel Control & Setup Program (see “Chapter 5: Channel Control and Setup Program” on page 27) has an output of 0 mA.
Alarm Indications This section describes the Rig Monitor in alarm 1, alarm 2, and fail conditions and suggests response to these conditions. Table 5 below lists the alarm indications for each condition. NOTE: The Beacon 200 Rig Monitor includes alarm on and alarm off delay settings for each channel and level of gas alarm. The alarm indications described in this section operate according to the factory set delay settings. See “Configure Channel Settings Menu” on page 29 for all the factory settings.
NOTE: You can select normally energized (NE) or normally de-energized (NDE) channel relay settings in the Channel Control & Setup menu. The following sections describe the default setting for the channel relays which is NDE. Common alarm 1 and alarm 2 relays are factory-set as NDE, and the common fail relay is factory set as NE. The common relays’ NE/NDE settings are not user-adjustable.
Alarm 2 Condition This section describes the audible and visual indications for an alarm 2 condition and suggests response to an alarm 2 condition. Alarm 2 Condition Indications When the gas reading of an active channel 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 light turns on. • The gas reading in alarm 2 condition continues to flash and alternates with the ALARM-2 messages.
• 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.
