Chapter 6: Trouble shooting

This chapter describes how to handle errors in the system and what mea-

sures to take. That includes the handling error log, list of error codes and how

to contact ABB.

Trouble shooting should be done by authorized personnel who are familiar

with the Arc Guard System, the setup as well as the environment where it is

located.

Trouble shooting should take into consideration:

• History, including events just before an arc

• Situation, circumstances when an arc occurred

• Environment, temperature, vibrations, power supply, electrical/magnetic distur-

bances

• How an arc is indicated and nature of its occurrence

• The different Arc Guard System modules and all connections

This section presents diagnostics and describes how to handle the error log.

It includes view logs and error codes.

The Arc Guard Systems is often operated without any personnel present.

The error logging function is a way to store information about past events for

future reference in order to facilitate trouble shooting. Performing diagnostics

is a check on the system status and its error events.

An error event indicates an error in the system. Example of error events is:

• Overcurrent for a long time period.

• Optical detectors that detect light for a long time period.

• DIP switch is changed physically while Arc Monitor is powered.
