Gen Set signalling
If an Emergency generator set supplies the UPS in case of utility failure and the generator is
particularly unstable in frequency, it should be suitable to install the signal "generator on" on
terminals X1 / 11, 22 (Normally Open voltage-free contact) or on connector J2 / 11, 24 (see Fig.
10.2.1-1 / X1 and J2).
When this contact closes, it causes the change of certain settable functions such as:
•
Enabling or disabling of synchronisation and consequently the load transfer to generator.
•
The battery recharge inhibition during the generator operation, or after what delay from
generator start the battery will start to be recharged.
Consult your nearest Service Centre for more information.
