5.11. 86 Function. Trip Output Lockout
When the trip output is configured like OR_LACTH the programmable logic allows this
output to block.
5.12. Self-diagnosis
Diagnostic algorithms are run while the equipment is being picked up and continuously
when the relay is operating. This diagnostic is a preventative process to guarantee that the
equipment is in good operational condition.
The following general considerations are applicable:
•
Communications between different CPUs are confirmed by the corresponding integrity
checks. In the case of continuous faults, the equipment shall be re-picked up.
•
The settings details are confirmed with the corresponding checks. Also, the settings
tables are folded and the relay can operate with one table damaged but not with two
damaged.
•
There is a WatchDog mechanism between the different main CPUs, as well as on the
CPUs themselves. Loss of activity on any of these will result in the resetting of the
equipment, and this will be recorded as an event.
The following status bits are associated with this process:
Measurement error
Problem in the measurement block
Protection error
Problem in the protection block
Eeprom Error
Problem in the eeprom memory, a table is corrupt.
Event error
Problem in the events recording
On the other hand, a default settings error indicates that the relay is operating with default
settings, whereby it will not trip (check that the relay alarm is activated with default
settings).
