What does it mean if my Riello UPS display shows codes F06, F07, or F08?
If the Riello UPS display shows one or more of the following codes: F06, F07, F08, it means that the input switch is short-circuited. Operate the manual bypass (SWMB), switch the UPS off, open SWIN and contact your local service centre (caution: once SWIN has been opened, it cannot be closed before the service centre works on the system).
What does it mean if my Riello UPS display shows codes A08, A09, or A10?
If the Riello UPS display shows one or more of the following codes: A08, A09, A10, it could indicate no connection on one or more phases. Verify the terminal connections. It can also mean that fuses are broken inside protections on input phases. In this case, call the nearest service centre.
What does it mean if my Riello UPS display shows codes F42, F43, F44, L42, L43, or L44?
If the Riello UPS display shows one or more of the following codes: F42, F43, F44, L42, L43, L44, it means that the fuses inside protections on batteries are broken. Call the nearest service centre
Why is my Riello UPS operating from the battery when mains voltage is present?
If your Riello UPS operates from the battery even when mains voltage is present, it could be due to upstream protection intervention. In this case, reset the protection, ensuring there is no output overload or short circuit to the UPS. Alternatively, the input voltage may be outside the acceptable range for mains operation. If so, wait for the input mains voltage to return within the tolerance range; the UPS will automatically switch back to mains operation.
What should I do if the display on my Riello UPS is blank or showing incorrect information?
If the Riello UPS display is blank or gives incorrect information, it indicates that the display is having power problems. Close Manual Bypass (SWMB) keeping closed INPUT and OUTPUT switches. Open input switch (SWIN and SWBYP) and wait until UPS is completely turned OFF. Turn ON SWIN and SWBYP again and verify display regular operation. Exclude the maintenance bypass. If the fault persists, contact the nearest technical support centre.
What does it mean if my Riello UPS display shows codes A13, A14, or A15?
If the Riello UPS display shows one or more of the following codes: A13, A14, A15, this could be due to the bypass line upstream protection being open (with separate bypass only). Reset the upstream protection, ensuring there is no output overload or short circuit. Alternatively, the bypass switch (SWBYP) may be open. Close the switch located behind the door.
What does it mean if my Riello UPS display shows codes F37, L37?
If the Riello UPS display shows one or more of the following codes: F37, L37, the issue might stem from ambient temperature exceeding 40°C, heat sources near the UPS, obstructed ventilation slits, or a temperature sensor/battery charger cooling system malfunction. Remove the cause of over-temperature. Insert manual bypass (SWMB) without switching off the UPS and wait for battery charger temperature to lower. Exclude manual bypass. Contact the nearest service centre if this problem persists
What does code S07 mean on my Riello UPS display?
If your Riello UPS display shows code S07, it means the batteries are flat, and the UPS is waiting for the battery voltage to exceed the set threshold. Wait until the batteries have recharged, or force power-on manually via the “ON” menu.
What does it mean if my Riello UPS display shows codes A30, A32, A33, A34 and the UPS will not start up?
If the Riello UPS display shows one or more of the following codes: A30, A32, A33, A34 and the UPS will not start up, this may be due to an ambient temperature below 0°C. Heat up the room, wait for dissipater temperature to exceed 0°C and start up the UPS. It can also be caused by a dissipator temperature sensor fault (dissipator temperature < 0°C). In this case, activate manual bypass (SWMB), switch off the UPS, re-start the UPS and exclude manual bypass. Call the nearest service centre if this problem persists.
What does it mean if my Riello UPS display shows codes L26, L27, or L28?
If the Riello UPS display shows one or more of the following codes: L26, L27, L28, it indicates a short-circuit in the output. To resolve this, switch off the UPS, disconnect all utilities related to the short-circuited phase, switch the UPS back on, and reconnect utilities once the fault has been identified.
