7.7.6 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.
7.8 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.
7.8.1 Optical and acoustical error messages
Error message
in the display
Acoustic
alarm
Description of the alarm Removing the fault
Overload
(output overload)
Two bleeps
per second
The UPS is overloaded. The load needs
more power than the UPS can deliver. The
UPS is providing power via the bypass.
Reduce the load by switching off
unimportant consumers
Battery test
(battery test)
UPS performs a battery test
No handling necessary.
The UPS switches again to normal
operation after a successful battery test
Overcharging
(over-charge)
Continuous
tone
The batteries are over-charged. (Battery
charge voltage too high)
Contact the service hotline!
Battery discharged
(low battery)
Two bleeps
every 5 sec.
The UPS operates in autonomy mode
(loss of input mains) and the final
discharge voltage has almost been
reached.
The UPS is automatically started again
when the input mains network is
available again! No handling is required!
Battery operation
(on battery)
A bleep
every 5 sec.
The UPS operates in autonomy mode
(loss of input mains)
Save your data and shut-down your
computer in a controlled fashion.
Battery charge fault (charger
failure)
Continuous
tone
Battery charger defective Contact the service hotline!
Over-temperature
(over-temperature)
Continuous
tone
Temperature within the UPS is too high
Ensure that all fans on the UPS are
running and are not blocked or dirty
Short circuit on output side
(output short)
Continuous
tone
Short-circuit on the consumer side Contact the service hotline!
High output voltage
(High output voltage)
Continuous
tone
Overvoltage on the consumer side Contact the service hotline!
Bus fault
(Bus fault)
Two bleeps
per second
Excessively high voltage on the DC side Contact the service hotline!
Reverse polarity fault
(site wiring fault)
One bleep
per second
Voltage detected between N and PE
Deactivate the reverse polarity protection
in the menu
Mains fault
(line abnormal)
One bleep
per second
Synchronisation failed New start
Battery fault 3 x bleep No battery or a faulty one
Switch off UPS using the ON/OFF button
Connect up a battery.
P L E A S E N OT E!
The UPS unit must be started again after change-over to generator mode.
