5.2.5 X1 terminal block - Gen Set Signalling (GEN ON)
If an emergency generator set supplies the UPS in case of Utility Failure and the generator is
considerably 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 password protected, call the nearest
Service Center 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 “GENERATOR ON” input contact is closed, the UPS will inhibit eBoost™ Operation
Mode and revert to double-conversion operation.
It is advised to contact your Service Center for further details.
In a Parallel System a separate NO (Normally Open) contact must be connected to
each individual unit.
