7.4.1.3. Restarting
The detection of an error or defect by the self-testing and moni-
toring functions during normal operation initiates the following:
· Processing by the protection functions is stopped and their
operation blocked.
· The binary outputs are reset and further operation blocked.
This includes resetting the ‘Relay ready’ signal, if it was acti-
vated.
· The stand-by signal (green LED on the frontplate) flashes.
Communication between the PC and the protection equipment
remains intact, however, and provides facility for localising the
cause of the problem.
Blocking of the protection is maintained until an attempt is made
to restart it by pressing the reset button on the frontplate. Should
restarting be successful, but the original defect still exists, the
same sequence is repeated and the protection is blocked once
again.
