3.3 Remote Sensors Installation

Conduit Version (P/N: 231GRSX3MX)

For conduit version remote sensors, use the following instructions:

1. Install the remote sensors into the system plumbing (use 3/4” hex to tighten”)

Important:

Each remote sensor is labeled “HIGH PRESSURE SENSOR” or “LOW PRESSURE SENSOR”, respectively. Match up

the high pressure sensor to the high “HI (+)” pressure electrical terminals, and the low “LO (-)” pressure

sensor to the low pressure electrical terminals. Otherwise, the performance may not meet the product

linearity specications.

2. Install a 1/2” conduit tting into the remote sensor top cover and fasten the retaining nut.

3. Feed wires from a exible conduit through the remote sensor top, cover fasten the wires to terminals.

4. Screw on the top cover.

5. Fit conduit into conduit tting, and tighten conduit watertight strain relief.

To connect the wires from the remote sensor to the unit, remove the terminal blocks from the circuit board and use

the following chart:

Installation of the Model 231RS is now complete.
