4 LED Display
LED green:
The LED is green as long as an input voltage (>20 V DC) is present.
LED orange:
The LED turns to orange as soon as the DC UPS UPSI-B-2410 switches
to battery mode (input voltage <20 V DC).
LED red/orange-flashing:
The LED flashes red/orange in battery mode when the capacitance of the
connected battery pack decreases (battery voltage dropping to <21 V).
LED red/green-flashing:
The LED flashes red/green
when the connected battery is discharged or defect.
when the battery supply line or fuse is defect.
3 Functional Description
In case of a mains voltage failure the DC UPS UPSI-B-2410 supplies the connected
consumer load with DC voltage from the connected battery pack. Via LED display the
status is visualised. Signals can be informed to a connected PC via interface.
3.1 Mains Mode
In mains mode a voltage source at the input line supplies 24 V DC. This voltage minus
0.4 V DC is provided directly at the consumer load (e. g. PC). The connected battery
pack is charged by the UPSI-B-2410. The LED is green and the interface signalises
“Power ok“. App. every 10 minutes a battery test is carried out. In case of a defect
battery or if the battery pack is not connected, the LED flashes red/green.
3.2 Battery Mode
If the supply voltage drops below the switch-over threshold at the input of the
DC UPS UPSI-B-2410, the UPSI-B-2410 takes over supplying the connected consu-
mer loads. The LED is orange and the interface signalises “Power Fail“. When the
capaci-tance of the connected battery pack decreases (battery voltage dropping to
<21 V), the interface signalises “Battery Low“. The LED flashes red/orange. The DC UPS
UPSI-B-2410 can be switched off by an impulse at the “Shutdown“ input.
