Earth Fault Detection

Overview

This appendix contains instructions on how to use the Earth Fault Search feature of the

 

4100U-S1 diagnostics menus.

 

Earth Fault Search is a diagnostic search of external field wiring that assists in locating

 

circuits with earth faults. An earth fault occurs when an electrical circuit is shorted to

 

ground. Although most circuits operate with a single earth fault, multiple earth faults can

 

disable communications. Because of this, earth faults must be located and repaired.

 

Earth Fault Search is conducted by the 4100U-S1. The diagnostic may be activated using

 

either the front panel interface or the Computer Port Protocol via a service port.

The 4100U-S1 supports two types of Earth Fault Searches:

Location Search. Searches all circuits at a location, such as the main panel.

IDNet Channel Search. Selectively enables channel isolators and repeaters to detect which segment of the channel wiring has a fault.
