Explanation
60
Mains parallel operation is desired: Clear blocking of GCB ↔ MCB
Relay is set if the MCB or the GCB are synchro-
nized and if
MCB + GCB are closed (NPB)
61 Overcurrent I/t or generator overcurrent level 2 UMZ
62 Introduce load-shedding: Add-on / Sync. GCB carried out or circuit
breaker is closed
Signal is set prior to connection / synchronization
and remains present when circuit breaker is
closed.
63 Add-on / Sync. MCB carried out or circuit breaker is closed Signal is set prior to connection / synchronization
and remains present when circuit breaker is
closed.
64 Overspeed pickup
65 Emergency power is active
66 Shutoff malfunction
67 Power watchdog for power supplied by the mains
68 Maintenance call
69 Pickup/gen. differential frequency The electrically determined speed and the speed
determined via pickup are different
70 Time monitoring alarm "synchronization MCB" or "add-on MCB".
71 GCB synchronization carried out
72 MCB synchronization carried out
73 Lamp test active
74 Malfunction "Reply: GCB is open" - alarm on closing The GCB cannot be closed after 5 attempts.
75 Malfunction "Reply: MCB is open" - alarm on closing The MCB cannot be closed after 5 attempts.
76 Malfunction "Reply: GCB is open" - alarm on opening 2 s following the "Command: GCB open" a reply
continues to be detected.
77 Malfunction "Reply: MCB is open" - alarm on opening 2 s following the "Command: MCB open" a reply
continues to be detected.
78 Power supplied by the mains <> 0 In the event of interchange synchronization, the
incoming power zero cannot be adjusted. As a re-
sult of this, the MCB is prevented from opening.
Reset via acknowledgment.
79 Isolated operation in parallel with other gensets /operatin in parallel with
the mains
80 Synchronization on MCB and NPB Relay is set if,
1.) MCB synchronized
2.) if MCB + GCB are closed (NPB)
3.) if GCB synchronized on
closed MCB
→ no synchronization on IPB
→ for voltage controllers which are only operated
in parallel with the mains.
