LED signalization, outside the power supply.
MAINS green LEDdiode
Reaction
time
0 - no mains, battery disconnected (no-voltage condition) x
1 - mains on, rectifier operational 0
0/1 pulsowanie - battery operation (no mains or rectifier faulty) 0
FAULT yellow LED diode
0 - no faults
1 - battery operation (no mains power supply or rectifier faulty)
- no battery, or the battery has voltage lower than 10V - LVDD remains off
- battery disconnected or battery fuse blown out [**]
- decrease of output voltage of power supply down to level lower than 90% of
floating voltage. **)
- battery voltage below 22V **)
- mains voltage below 175V
- battery circuit resistance too high [*]
- output fuse blown
- fuse in additional outputs module (if attached) blown 0

0/1 flashing - external alarm or internal alarm (open cabinet doors, tamper) *) 0
0/1 blinking - recognized battery (U> 10V) but has too low voltage (U <21.6V) - RGR remains
switched off x
*) Alarms are not distinguished
**) Fast voltage drop when overloading the power supply activates the 22V signalization. Slow lowering starts the
90% signalization (after 1 minute from exceeding the threshold). When the battery is being charged, the alarm is
cleared after exceeding the 22V threshold.
Reaction time:
0

x
– the selected rows describe permanent states of operation preceding the start of the power supply.
LED signalization inside power supply (PCB packet)
MAINS green LED
Reaction
time
0 - no mains 0
1 - mains on, rectifier operational 0
0/1 blinks - mains on, damaged rectifier 0
BAT yellow LED
0 - battery correct [**] 0
1 - high resistance of battery circuit [*] 12min
0/1
pulsowanie - no battery or battery fuse blown 90s
[*] The measurement is performed every 10 minutes. The first detected overrun activates the signalization on the
BAT PCB packet and reduces this time down to 1m. After detection of the next two exceedances, the FAULT
external signalization is activated. Thus, the maximum detection time of the exceedance is 12 minutes. The first
correct measurement cancels the signal.
[**] When the battery fuse is faulty or the battery has been disconnected, the LVDD is automatically switched off
due to the voltage drop below its level. Reconnecting the battery or replacing the fuse results in the LVDD being
switched on without delay.
Relay signalization
MAINS FLT Mains fault
Reaction
time *)
0 - no mains (only mains, does not react to rectifier fault)
1 - mains on
GEN FLT General fault
0 - whenever FAULT LED is on, flashes or blinks
1 - no faults
0
–de-energized relay
1
–energized relay
*) The
MAINS FLT and GEN FLT relays react to the power failure and its return with delay of 6s.
The GEN FLT relay immediately follows the FAULT signalization.
