Generator mode
Generator mode (adjustable via the panel) ensures that the UPS unit is not constantly switching over to battery
operation, since the output voltage of the generator often demonstrates distortions or irruptions, but remains in
online mode and thus a sinusoidal output voltage for the consumers is achieved.
This functionality has a low loading effect on the battery which means that the working life of the battery is
maintained.

Error messages and their removal
This trouble-shooting instruction offers simple tips about how faults can be located and removed.
If an error message occurs in the function display then you may well be able to remove the fault yourself using
these trouble-shooting instructions.
The UPS emits acoustic error signals for:
-
A mains fault; the UPS unit runs in battery mode and the alarm sounds every 5 seconds.
-
Battery discharge; unit runs in battery mode and the alarm sounds twice every 5 seconds.
-
Internal error in the UPS; the alarm sounds continuously
The acoustic alarm can be silenced by pressing any key.
P L E A S E N OT E!
The UPS unit must be started again after change-over to generator mode.
Summary:
Free running mode
On, bypass deactivated
A fault occurs
CPU on UPS checks whether the
narrow input frequency window (±2%) and voltage window is being maintained
if parameter OK
no
switch-over to bypass
since bypass is deactivated
Free running mode
On, bypass activated
A fault occurs
CPU on UPS checks whether the
narrow input frequency window (±2%) and voltage window is being maintained
if parameter OK.
Switch-over to bypass
since bypass is activated.
