Maintenance Events - GE MiCOM P747 Agile Technical Manual

Chapter 6 - Monitoring and Control
Note:
We recommend that you do not set the triggering contact to latching. This is because if you use a latching contact,
the fault record would not be generated until the contact has been fully reset.

MAINTENANCE EVENTS

Internal failures detected by the self-test procedures are logged as maintenance records. Maintenance
records are special types of standard events.
The event type description shown in the Event Text cell for this type of event is always Maint Recorded.
The Event Value cell also provides a unique binary code.
The IED contains a separate register containing the latest maintenance records. This provides a convenient
way of viewing the latest maintenance records and saves searching through the event log. You access these
fault records using the Select Maint setting.
The maintenance record has a number of extra menu cells relating to the maintenance event. These
parameters are Maint Text, Maint Type and Maint Data. They contain details about the maintenance event
selected with the Select Maint cell.
The possible maintenance records are as follows:
Event Value Event Text
6 FPGA Health Err
7 IO Card Error
9 Code Verify Fail
14 Software Failure
15 H/W Verify Fail
16 Non Standard
17 Ana. Sample Fail

There is a system error
The device has been requested to reboot
There is an unrecoverable internal error. The device will reboot after the maintenance record has been
created
A lockout has been requested. This is generated whenever maintenance access is gained through the
USB port
There has been an I/O upgrade failure. This can be caused by a faulty I/O card, or the boot loader
enable bit on the micro-controller being disabled
