Overview

Non-Point Faults

There are several types of results that can display at the end of an Earth Fault Search. This section covers all types of results.

IMPORTANT: Once you have been directed to an earth ground fault and corrected it, it is recommended that you restart the system (warm- or cold- start).

A non-point fault indicates a ground that cannot be traced to an addressable point (for example, a shield or an audio riser). The earth fault in this example is not occurring at the audio controller but somewhere in the riser:

CARD 17, ANALOG AUDIO CONTROLLER

AUDIO RISER 1

EARTH FAULT

Non-point faults can be displayed for each of the following items:

•Shield (Flex 50/100 W Amplifier)

• Audio Riser (Digital./Analog Audio Controller; Local Mode Transponder; may also annunciate as "DAR SECONDARY" (Digital Audio Riser Secondary) on transponder)

 

• Remote Mic 1 and Push-to-Talk line (Digital./Analog Audio Controller) (other

 

remote mics are not supported)

 

 

 

• Channel Output (IDNet Card; MAPNET Interface Card)

 

• RUI Channel (Master Controller Card)

 

 

 

• Channel 1 to 3 (TrueAlert Power Supply)

 

 

Point Faults

 

 

 

A point fault indicates a ground at a specific addressable point. The example below is a

 

location earth ground search result, where 3 is the card address, 10 is the point number,

 

and 0 is the

 

 

 

sub-point number (not used):

 

 

 

 

 

 

 

 

CARD 003, FLEX 50 AMPLIFIER

 

 

 

3-10-0

EARTH FAULT

 

 

Point faults can be found at any point in the system that connects to field wiring.

 

Some IDNet channel point fault examples are illustrated below.

 

Fault not cleared. The message below shows that an IDNet channel that has been

 

isolated for fault detection still has the earth fault:

 

 

 

 

 

 

 

 

CARD 2, IDNET CARD (250 POINTS)

 

 

 

M1, EARTH FAULT SEARCH

FAULT CLEAR FAIL

 

 

Fault between channel output and first isolator. The message below shows a fault

 

between the IDNet channel output and the first isolator on the line:
