Troubleshooting P - ABB Arc Guard System TVOC-2 Installation And Maintenance Manual

50 ABB ARC GUARD SYSTEM™ – T VOC-2 INSTALL ATION AND MAINTENANCE GUIDE
7.1 Introduction
This chapter describes how to handle errors in the system
and what measures to take. That includes the handling
error log, list of error codes and how to contact ABB.
7.2 Requirements
Troubleshooting 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.
Troubleshooting should take into consideration:
• History, including events just before an arc.
• Situation, circumstances when an arc occurred.
• Environment, temperature, vibrations, power supply,
electrical/magnetic disturbances.
• How an arc is indicated and nature of its occurrence.
• The different Arc Guard System™ modules and all
connections.
Handling Error log
This section presents diagnostics and describes how to
handle the error log. It includes view logs and error codes.
Diagnostics
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.
7.3 Errors
Error event
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.
• HMI display has lost contact and can not communicate
with Arc Monitor.
Error Log
• During diagnostics the error events are logged in
the Error Log. In the Error Log the error events are
represented by error messages. Each message includes
a code that gives information about the specific
occurred event and the time stamp it occurred.
The log is a circular buffer. It stores nine error events.
The oldest will be overwritten.
Error indication
When a system error occurs the HMI display a notification
window.
The window displays are:
• System Error
• Error code
• Time and Date
