What does it mean when my Riello UPS display shows codes C01, C02, or C03?
If the display of your Riello UPS shows one of the following codes: C01, C02, C03, it indicates that a remote command is active. If this is unwanted, check the status of the command inputs on any optional contact card.
What does C02 mean on my Riello VST 2000 display and how do I fix it?
If the display on your Riello UPS shows C02, the “BATTERY SWAP” mode is activated. To exit this mode, press and hold the ON/SEL buttons for at least 4 seconds.
Why is my Riello UPS operating from the battery even with mains voltage present?
If your Riello UPS is operating from battery despite mains voltage, it could be due to the input voltage being outside the permitted tolerance range. In this case, the solution is to wait until the input mains voltage returns within the tolerance range, at which point the UPS will automatically return to mains operation. Another cause may be intervention of the input circuit breaker. If present, reset the circuit breaker by pressing the button on the back of the UPS, being cautious of a potential output overload.
How to troubleshoot a Riello VST 2000 UPS when the display does not light up?
If the display of your Riello UPS doesn't light up, first, ensure that you have pressed the ON/OFF switch on the front panel. If it still doesn't light up, check that the power cable is correctly connected. Also, verify that there is mains voltage by testing the socket with another device, like a table lamp. Finally, check for intervention of the input circuit breaker. If present, reset the circuit breaker by pressing the button on the back of the UPS, being cautious of a potential output overload to the UPS.
What to do if the buzzer sounds continuously and the display shows codes A54, F50, F51, F52, L50, L51, or L52 on my Riello UPS?
If the buzzer of your Riello UPS sounds continuously and the display shows one of the following codes: A54, F50, F51, F52, L50, L51, L52, it indicates that the load applied to the UPS is too high. To resolve this, reduce the load to within the threshold of 100% (or the user threshold in the case of code A54). If the display shows a lock, remove the load and switch the UPS off and back on again.
What to do if my Riello VST 2000 display is on, but the load is not powered?
If your Riello UPS display is on but the load is not powered, first, check if the UPS is in standby mode. If so, press the ON button on the front panel to power the loads. If it is not in standby mode, check the connection to the load.
What does it mean if my Riello UPS buzzer sounds continuously and shows code F38?
If the buzzer of your Riello UPS sounds continuously and the display shows code F38, it means the UPS is malfunctioning and may lock soon. Disconnect the power to the load if possible, then switch the UPS off and back on again. If the problem persists, contact the support center.
Why doesn't my Riello VST 2000 turn on and the display shows error code A06 or A08?
If the Riello UPS does not come on and the display shows the code A06 or A08, it indicates that the temperature of the UPS is lower than 0°C. Check the temperature of the environment where the UPS is located and, if necessary, bring it above the minimum threshold of 0°C.
Why does my Riello VST 2000 buzzer sound continuously and show error codes F04 or L04?
If the buzzer of your Riello UPS sounds continuously and the display shows one of the following codes: F04, L04, it means that the temperature of the heatsinks inside the UPS is too high. Check that the environment temperature does not exceed 40°C.
What should I do if my Riello UPS buzzer sounds continuously and shows error codes F53 or L53?
If the buzzer of your Riello UPS sounds continuously and the display shows one of the following codes: F53, L53, there is a fault on one or more of the utilities powered by the UPS. Disconnect all the utilities, switch the UPS off and back on again, then reconnect the utilities one at a time to identify which one is faulty.
