3.3 Hardware Fault Diagnostics
Fault Condition Possible Solution
Screen Blank, no Signal Check Wiring, check fuses.
Distorted MA Signal Output jumper set to voltage.
Voltage signal pinned high Output jumper set to mA
No mA Signal on AC floating power supply Check for signal common line.
Check for signal operation by using on-board test
points
Bad RS-485 Communications for this unit. Check wiring polarity for A & B lines
Check for correct line terminations.
Check for correct address.
Bad RS-485 Communications for a multi-drop
group.
Check wiring polarity for A & B lines
Check for correct line terminations.
It is possible for one failed device on a multi-drop
line to pull communication down for the whole line.
Check for correct addresses.
