ATYS 520 B GB
• A fault can cause an important damage -> the genset
must be stopped immediately.
• During one supply operation (G1 for example), if Ft1
appears, the second supply (G2 in that case) is
imme-
diately
started. The initial G1 genset is then stopped
immediately
after the transfer. The emergency genset
G2 will then be maintained as long as Ft1 will be
present. After Ft1 disappearance, the basic cycle will
take over.
