1. For remote mounted electronics, carefully check all the wiring connections in the remote mount junction box.

There are 18 connections that must be correct. Verify each color (black and red), shield, and wire number.

2. Using ESD precautions and hazardous area precautions, remove the electronics enclosure window cover.

Disconnect the pressure sensor from the electronics stack (see Figure 78 on page 119) or the remote feed

through board (see Figure 79 on page 119). Measure the resistance across the outside pins of the pressure

sensor connector, then across the inside pins (see Figure 82 below). Both readings should be approximately

4000 ohms.

3. Go to the first column of the hidden diagnostics and record the

findings.
