The standby circuit checks test was a planned evolution that was not intended to cause a start of the EDG.

The EDG was secured at 13:03, after functioning successfully.</br>The EDG was not started by a valid initiation signal. A valid initiation signal is degraded or loss of voltage to the Power Board (PB) 103.
