6 Troubleshooting
PC System crash during UPS mode
Connection interrupted or defect fuse on battery side
Connected load <10 W (load sensor)
Battery pack has not enough capacitance or is discharged
Battery fail (Battery defect)
The LED flashes red/green
when the internal battery pack is discharged or defect.
when the battery supply line or fuse is defect.
For further display schemes please have look at page 21.
The UPSI-1202 does not switch off in connection with RUPS 2000-B1.
The checkmark under “
Settings
“, “
Shutdown
“ and “
Switch off UPS
“ (
USV
abschalten
) was not set.
The shutdown suppression period (see 5.4) was disturbed, and the shutdown
impulse was, thus, “suppressed“.
The interface cable is defect or a wrong interface cable was used.
Battery is not fully charged
Battery pack defect
No function
Polarity reversal of input voltage? >> internal fuse defect
Please contact our service!
Upstream input fuse defect? >> replace input fuse
The overvoltage protection at the input (from 17 V DC) was activated.
Short circuit of internal suppressor diode blows input fuse and the UPSI-1202
switches to battery mode.
DC source supplies too less peak current, UPS shuts down
Overload at output due to high peak current. The UPS shuts down (LED lights red).
