to the interior of the junction box. The combustible gas detector is a catalytic type detector that produces an electrical output that corresponds to the detection range. It is packaged in a 1/2 inch NPT nipple with a sintered metal flame arrestor on one end allowing ambient air to diffuse into the detector. The flame arrestor also contains any sparks which may occur within the detector. The calibration cup/splash guard is screwed onto the bottom of the detector.
The H2S detector is factory wired through the middle cable bushing of the Beacon 200 and has a 25 foot cable for remote installation. The mounting bracket at the top of each junction box is used to mount the junction box. The junction box protects the detector wiring connections. Three spacers installed on the back of the junction box control the distance of the junction box from a mounting surface and ensure that there is enough room to perform a calibration.
12 VDC Battery Cable A 50 foot cable with clamps for connection to a 12 VDC battery (customer supplied battery not included) is factory-wired through the right cable bushing of the Beacon 200. One end of the cable is connected to the DC In terminal strip. 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.
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 5). • 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 17 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 30 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.
