Connecting a Recorder

Perform the following procedure to connect an analog 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 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.
