Protect-5:
The standby time is determined by calculating the balance of the
battery currents.
Parameters to be set and their setting ranges:
Discharge currents Corresponding discharge times
I1: 1 – 9999 A t1: 1 – 999 min
I2: 1 – 9999 A t2: 1 – 999 min
Moreover, the set values must fulfil the following conditions:
t2 / I1 > t1 / I2
t2 > t1
I1 > I2
ATTENTION:
If a communication error with the respective control system occurs
during the saving process, the setting procedure must be repeated.
10.1.3 Battery Tests
The implemented battery tests depend on the unit type and can be
started and cancelled via the "SERVICE / BATTERY TEST" menu of
the DOU. Status messages and measured values of the battery
branches are shown in the display. The yellow LED signals an
ongoing test. The tests are either completed successfully, completed
with an error or cancelled manually.
The test parameters are set using the "SERVICE / BATTERY
VALUES" menu. This menu allows the operator to set the discharge
current, the maximum discharge time and the minimum battery
voltage for each type of test.
Prerequisites for initiating the tests:
The UPS is in normal operation (no fault is present)
• The rectifier is switched on.
- Note/Connection is possible using the DOU
• The battery charger is running in trickle charge mode.
- Note/Switchover is possible using the DOU
• The INV is running.
- Note/Connection is possible using the DOU
• The battery is installed.
• The last test was conducted at least 1 minute previously
