What to do if the 'Fault' LED lights up and the warning signal sounds twice per second on my AEG PROTECT 1?
If the 'Fault' LED is illuminated and the warning signal sounds twice per second, this indicates an overload of the AEG UPS system. To resolve this, immediately reduce the capacity utilization of the UPS by disconnecting some of your loads.
Why are the 'Line' and 'Fault' LEDs lit with a continuous warning signal on my AEG UPS?
The simultaneous illumination of the 'Line' and 'Fault' LEDs accompanied by a continuous warning signal indicates a switch-off due to the AEG UPS's internal overtemperature detection. Ensure that there is no overload, the UPS fans are not blocked, and the ambient temperature is within the correct range. Allow the UPS to cool down for 10 minutes before switching it back on.
What to do if the AEG UPS switches to battery mode?
The AEG UPS switches to battery mode because the mains voltage supply has been interrupted. Try to re-establish the mains voltage, checking for triggered fuses. If the acoustic signal sounds every second, the battery is almost completely discharged. Immediately perform a system shutdown of your IT equipment.
How to troubleshoot no display and no acoustic signal on my AEG UPS?
If there is no display and no acoustic signal, even when the system is connected to the mains, the mains and/or battery voltage may be outside the tolerance range, or the battery may be totally discharged. Check the mains connection, the back-up fuse, and the mains input miniature circuit breaker.
Why is the emergency power supply duration shorter than expected on my AEG PROTECT 1?
The emergency power supply duration might be shorter than the setpoint because the batteries are not completely charged or they are aged or faulty. Charge the batteries for at least the recharging time. If the problem persists, contact your dealer.
What does it mean when the 'Line' LED flashes and the 'Battery' LED lights up on my AEG PROTECT 1?
When the 'Line' LED flashes and the 'Battery' LED is lit, the mains voltage and/or mains frequency are outside of tolerance. Check the mains voltage and frequency.
What to do if my AEG UPS does not switch to bypass even when mains is OK?
If the AEG UPS does not switch to bypass even when the mains is OK, the mains input use may be in the “OFF” position. Switch the mains input miniature circuit breaker to “ON”.
How to fix error description no. 19 on my AEG PROTECT 1 UPS?
Error description no. 19 indicates a switch-off due to a short-circuit in the AEG UPS output. Correct the short-circuit, then switch the UPS on again, connecting loads one after the other.
What does it mean if the 'Fault' LED lights up, the 'Battery' LED flashes, and a warning signal sounds once per second on my AEG PROTECT 1?
If the 'Fault' LED lights up, the 'Battery' LED flashes, and the warning signal sounds once per second, this indicates a fault in the DC circuit or a faulty battery system. Notify your dealer.
