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 applicable detector
head.
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. Locate the recorder output terminals on the controller terminal
strip (see Figure 1).
3. Install an appropriately rated cable bushing in the Rig Monitor housing.
All 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.
4. Guide the wiring from the recording device through the new conduit
hub on the Rig Monitor.
