unstable in frequency, it should be suitable to install the signal “
GENERATOR ON
” on
X1 / 11, 22
.
See Fig. 5.2-1 / X1.
Since the Parameter for of the reading of the Generator function is “Service Code” protected, call the nearest ABB
Service Centre for it's activation.
When this contact closes, it changes certain (programmable) functions such as:
•
Enabling or disabling of synchronization and consequently the Load transfer to generator.
•
Reduction or elimination or delay of Battery recharging during the generator operation.
Additionally, when the “

and revert to double-conversion operation.
It is advised to contact your ABB Service Center for further details.
In a Parallel System a separate NO (Normally Open) contact must be connected to each
individual unit.
