The DC-UPS is equipped with an automatic “Check Wiring” and “Battery Quality” test.
“Check Wiring” test:
Under normal circumstances, an incorrect or bad connection from the battery to the DC-UPS or a missing (or blown)
battery fuse would not be recognized by the UPS when operating in normal mode. Only when back up is required
would the unit not be able to buffer. Therefore, a “check wiring” test is included in the DC-UPS. This connection is
tested every 10 seconds by loading the battery and analyzing the response from the battery. If the resistance is too
high, or the battery voltage is not in range, the unit displays “Check Wiring” with the red LED. At the same time the
green “Ready” LED will turn off.

“State of Health” (SoH) test:
The battery has a limited service life and needs to be replaced in a fixed interval which is defined by the specified
service life (acc. to the Eurobat guideline), based on the surrounding temperature and the number of
charging/discharging cycles. If the battery is used longer than the specified service life, the battery capacity will
degrade. Details can be found in chapter 27.1. The battery SoH test can not determine a gradual loss in capacity.
However, it can detect a battery failure within the specified service life of the battery. Therefore a SoH is included in
the DC-UPS.

The battery quality test consists of different types of tests:
During charging:
If the battery does not reach the ready status (see chapter 14) within 30h, it is considered to be defective.
The reason could be a broken cell inside the battery.
The reason could be a broken cell inside the battery.
During operation:
Once the battery is fully charged, a voltage drop test and a load test is performed alternately every 8 hours.
Three of the tests must consecutively produce negative results to indicate a battery problem.
Three of the tests must consecutively produce negative results to indicate a battery problem.
A battery problem is indicated with the yellow LED (replace battery pattern) and the relay contact “Replace Battery”.
Please note that it can take up to 50 hours (with the largest size of battery) until a battery problem is reported. This
should avoid nuisance error messages as any urgent battery problems will be reported by the “Check Wiring” test
and create a warning signal. The battery tests require up to 50h uninterrupted operation. Any interruptions in the
normal operation of the DC-UPS may result in the “Replace Battery” test cycle to start over.

When “Replace battery” is indicated, it is recommended to replace battery as soon as possible.
