IDNet isolator fault. The message below shows a fault detected after the IDNet isolator was turned on:

CARD 2, IDNET CARD (250 POINTS)

M1-3, IDNET ISOLATOR EARTH FAULT

If the message in the lower right corner of the LCD reads FAULT NOT FOUND (for a Location Earth Fault Search) or FAULT CLEAR FAIL (for an IDNet Channel Earth Fault Search), it means the search could not locate the fault, but it acknowledges that a fault exists.

There are three main possibilities behind this message:

•There are one or more internal wiring earth(s) in the system.

•There are system defects (hardware or software, such as a failed isolation circuit).

•An intermittent earth exists in the system (it occurs inconsistently and is therefore difficult to track via diagnostics).

•The cable to the service port may be grounded due to the remote PC's 3-pin plug. Run the laptop on batteries only, or, use an isolating transformer to the PC to get rid of this earth.

•The fault is on an auxiliary output that was excluded from the search.

The problem may have to be found manually and then corrected in some of the above scenarios.

If the message in the lower right corner of the LCD reads NO FAULT, it means the IDNet channel search could not locate any earth faults on that channel.

If the message in the lower right corner of the LCD reads RESULT NOT AVAILABLE, it means there is no result to view. This message comes up only when you have selected "Last Search Result" on the menu.
