• During the functionning of one supply (G1 for example),
if an alarm AL1 appears, the second supply (G2 in that
case) is started at the end of GFt1 timer. G1 genset
is then stopped after Cdt1 timer. The emergency
genset G2 will then be maintained as long as the alarm
AL1 will be present. After AL1 disappearance, the basic
cycle will take over.
