5.4.3 Symptom: No Output
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. Turn on the pressure and temperature display in the Display Menu and verify that the pressure and temperature
are correct.
3. Using ESD precautions and hazardous area precautions, remove the electronics enclosure window cover.
Disconnect the vortex sensor from the electronics stack (see
Figure 78 below) or the remote feed through
board (see Figure 79 below). Measure the resistance from each outside pin to the meter ground (see Figure 80
on page 120 ) - each should be open. Measure the resistance from the center pin to the meter ground - this
should be grounded to the meter.
