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.
NOTE:
Be sure to turn off the Beacon 110 Rig Monitor before connecting or disconnecting it
from the 12 VDC battery.
1.
Turn off, unplug, or disconnect all incoming power to the Rig Monitor.
2.
Open the housing door, then place the power switch in the OFF position.
3.
Connect the red battery clamp to the (+) terminal of the 12 VDC battery.
4.
Connect the black battery clamp to the (-) terminal of the 12 VDC battery.
Connecting External Alarms
Perform the following procedure to connect external alarms to the Rig Monitor’s Fail or Alarm 2
terminals. The Alarm 1 terminals are factory wired and are not available for field use.
1.
Disconnect the battery clamps from the + and - terminals of the 12 VDC battery.
2.
Open the housing door, then place the power switch in the OFF position.
3.
Locate the alarm terminal strip. See Figure 1 to assist you in locating the alarm terminal strip.
4.
Install an appropriately rated cable bushing in the Rig Monitor housing. Both factory supplied
conduit hubs are used in the Rig Monitor, so you will need to drill a hole in the housing for a
conduit hub and cable bushing.
5.
Guide the wiring of the external alarm through the new cable bushing.
6.
Connect the leads from the external alarm to the appropriate terminals on the alarm terminal
strip as shown in Figure 8 to obtain the desired operation.
