Replace Battery; Alarm Priority; Fault Mode; Stand-By - GE GT Series User Manual

4.4.6 Replace battery

Either the batteries are almost chemically worn out or the battery wiring, including the battery fuse, is
faulty. If the batteries are aged, they must be replaced as soon as possible to ensure full protection for
your equipment (see section 7.4.1 & 7.4.2). Perhaps the 'replace battery' alarm occurs after a test, which
was started immediately after installation or after a power failure. In this case the alarm may be incorrect,
as the batteries have been (partly) discharged during transport or storage or during the power failure. For
this reason we advise to execute battery test only after 5 hours on line operation with no mains
failures. This allows the UPS to recharge the batteries.

4.4.7 Alarm priority

'General alarm' comprises a group of alarms; the buzzer behavior indicates the priority of the generated
alarm.
ON: Battery not connected (see section 4.5)
1 / 0.5 sec.: Overload (see section 4.4.5)
1 / 4 sec.: General Alarm
1 / 60 sec.: Battery test failed (see section 4.5)
1 / 120 sec.: On bypass (see section 4.4.1)

4.4.8 Fault mode

The UPS may be in "fault mode" if the following failure occurred:
Fault Situation
!! Charger Over-voltage
!! Output Short Circuit
!! Negative Power
!! Overload
!! Over-temperature
= continuous - - - - = intermittent
In "fault mode", the UPS is "forced" on bypass or stand-by. After having solved the cause of the fault
condition you have to press the 'UPS off' button for 0.5 seconds to switch the UPS to normal mode or
restart the unit.

4.4.9 Stand-by

In stand-by mode the UPS is turned off (output power is lost) and the batteries are being recharged.
To put the unit in this condition press for 1 second the 'UPS off' switch, the unit switches to bypass.
Press one more time 'UPS off' switch for 1 second. The unit is now in stand-by mode. Most changes of
UPS settings are only possible in bypass or stand-by mode.
