2.12.4 Telecommunication Channel Monitoring
If a failure occurs or noise causes a disturbance in the telecommunication channel, this may
interrupt the data transmission or generate erroneous data, thus causing the relay to operate
incorrectly.
The GRL100 detects data failures by performing a cyclic redundancy check and a fixed bit check
on the data. The checks are carried out for every sample.
If the failure lasts for ten seconds, a communication failure alarm is issued.
The output blocking ceases instantly when the failure recovers.
