Micom P634 - Testing the Output Relays

If the self-monitoring detects a serious hardware fault (see those error messages
in Chapter 11, (p. 11-1), which lead to a blocking of the protection), all output
relays are reset regardless of the set operating mode or signal configuration.

Fig. 3-30: Testing the output relays.
For testing purposes, the user can select an output relay and trigger it via setting
parameters. At the time when the test is triggered the P634 must be switched to
“off-line”. Triggering persists for the duration of the set hold time.
