12.4. Prioritysourceautomaticrestorationsequence
This sequence is started as soon as the system is in AUTO mode and in position II. Specific function Automatic
retransfer inhibited: Once source 1 is restored, it may be preferable not to retransfer the load from source 2 to source
1 immediately. Once the retransfer from source 2 to source 1 is possible, the RETRANS function locks the retransfer,
and the AUT LED flashes pending the operator's confirmation.
The VALIDATION key must be pressed or an input must be programmed on RTC to authorise the retransfer.
