5.4 Test 

Screens 

 
These screens show the test procedure, either started from the service menu (front panel keys) or via the UPS 
monitoring software (RS232/SNMP). The upper line indicates the kind of test, the second line its status. 
 
Upper lines: 

second line: 

 

GENERAL SYSTEM 

TEST START

 

the test will start soon 

QUICK BATTERY 

TEST ACTIVATED

 

the test is running 

CALIBRATE BAT 

TEST SUCCESSFUL

 

the test has been completed successfully 

BYPASS 

TEST FAILED

 

the test has not been completed successfully 

 
 

5.4.1  Battery test, general 

 

Automatic test

: Every 500 operating hours the UPS conducts automatic battery tests to ensure that the 

batteries and the wiring are able to support power failures. The tests do not cause any interruption in the 
functioning of the unit. 

Manual test

: A manual battery test can be activated 

 

- 

either through an interface kit, via the RS232 or SNMP Interface Port (please refer to the 

manual of your interface package), or 
 

-  via the front panel: see below 

 
 

5.4.2  Quick battery test 

 
From the standard menu first enter the service menu (press the ‘Down’ and 'Enter/Reset' keys simultaneously, 
then press the ‘Down’ key until the following screen appears: 
 
 
 
 

QUICK BATTERY 

TEST PRESS ENTER 

The enter/reset key confirms the selection, and the screen shows: 
 
 
 
 

QUICK BATTERY 

TEST START 

 
The test status (indicated by the second line) can be: 

TEST ACTIVATED

 = 

testing 

TEST SUCCESSFUL

 

= 

battery has been tested with positive result 

TEST FAILED

 

= 

the batteries should be replaced 

NOT AVAILABLE

 

= 

battery capacity too low to start the test 

 
If the batteries are dangerously close to being worn out, a low priority alarm 'replace battery' will be generated. 
The batteries must be replaced as soon as possible (see section 8.3). 
NOTE: If the manual test is started immediately after installation or after a power failure, the UPS may generate 
a false 'replace battery' alarm as the batteries have been (partly) discharged during transport/storage or during 
the power failure.
