    What do error codes F34, F35, F36, L34, L35, L36 mean on my Riello MULTI SENTRY MST 60 UPS?
    • J
      Jonathan JohnstonDec 1, 2025
      If the display of your Riello UPS shows one or more of the codes F34, F35, F36, L34, L35, L36, it could be due to: * Ambient temperature exceeding 40°C * Sources of heat near the UPS * Obstructed ventilation slits or slits too close to walls To resolve this, activate manual bypass (SWMB) without switching off the UPS to allow the fans to cool the dissipator more quickly. Remove the cause of over-temperature and wait for the dissipator temperature to lower before excluding manual bypass. It may also indicate a temperature sensor or UPS cooling system malfunction. In this case, insert manual bypass (SWMB) without switching off the UPS so that fans can cool the dissipator more quickly. Wait for dissipator temperature to lower. Switch off and then re-start the UPS. Exclude manual bypas...

    What to do if Riello MULTI SENTRY MST 60 UPS does not go into standby mode with mains power?
    • K
      Kelly HamiltonAug 25, 2025
      If your Riello UPS doesn't enter standby mode despite mains power, check the following: * Ensure the mains are correctly connected to the input terminals as per the installation instructions. * Verify the neutral connection is present, as the UPS requires it to operate. Failure to connect the neutral can damage the UPS or the load. * Confirm the switch behind the door (SWIN) is closed. * Check for a blackout; verify the presence of mains voltage. If there is no mains voltage, switch on via batteries to power the load. * Check for upstream protection intervention and reset the protection, ensuring there is no output overload or short to the UPS.

    What to do if there is no load voltage arriving from my Riello UPS?
    • P
      Peter ParkerAug 26, 2025
      If there is no load voltage from your Riello UPS, consider these possibilities: 1. Check that the load is properly connected to the output terminals. 2. Ensure that the switch behind the door (SWOUT) is closed. 3. Verify that the UPS is not in standby mode. If it is, perform the startup sequence. 4. Confirm that the Stand-by OFF mode is not selected, as this mode only powers loads during blackouts. 5. If the UPS has malfunctioned and the automatic bypass isn't working, insert the manual bypass (SWMB) and contact the nearest service center.

    What does it mean when my Riello MULTI SENTRY MST 60 UPS shows codes A39, A40 and the replace batteries LED is on?
    • C
      Cindy LevineAug 27, 2025
      If your Riello UPS displays codes A39 or A40 and the red "Replace Batteries" LED is on, it means the batteries haven't passed their periodic efficiency test. It's recommended to replace the batteries, as they may no longer provide sufficient autonomy. Battery replacement must be performed by qualified personnel.

    What does code S07 mean on my Riello MULTI SENTRY MST 60 UPS?
    • B
      Breanna AllenAug 27, 2025
      If your Riello UPS displays code S07, it indicates that the batteries are flat and the UPS is waiting for the battery voltage to exceed the set threshold. You can either wait for the batteries to recharge or manually force power-on via the “ON” menu.

      If your Riello UPS displays one or more of the following codes: L01, L10, L38, L39, L40, L41, it indicates a malfunction of the temperature sensor, UPS cooling system, main auxiliary power, or static bypass switch. To resolve this, activate manual bypass (SWMB), switch off and re-start the UPS. Exclude manual bypass Contact the nearest service centre if this problem persists.

    What do error codes L11, L12, and L13 mean on my Riello MULTI SENTRY MST 60?
    • B
      Becky BrownSep 14, 2025
      If your Riello UPS displays codes L11, L12, or L13, it indicates a static bypass breakage or malfunction. To address this, activate manual bypass (SWMB), switch off the UPS, wait one minute, and then re-start the UPS. Exclude manual bypass. Contact the nearest service centre if this problem persists.

    What do error codes F06, F07, F08 mean on my Riello UPS?
    • M
      Melinda HarrisSep 15, 2025
      If your Riello UPS displays one or more of the following codes: F06, F07, F08, it indicates that the input contactor is blocked. To resolve this, activate manual bypass (SWMB), switch off the UPS, open the SWIN and contact the nearest service centre (Attention: once the SWIN is open, it will no longer be possible to close it again before Service intervenes).

    Why won't my Riello MULTI SENTRY MST 60 UPS start up and shows codes A30, A32, A33, A34?
    • S
      Scott LesterSep 6, 2025
      If your Riello UPS displays codes A30, A32, A33, A34 and won't start, it could be due to the ambient temperature being below 0°C. Heat up the room, wait for the dissipater temperature to exceed 0°C, and then start up the UPS. Alternatively, there may be a temperature sensor malfunction on the dissipator. 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.

      If your Riello UPS shows one or more of the following codes: F11, F14, F15, F16, F17, L06, L07, L08, L09, L14, L15, L16, L17, L18, L19, L20, L21, L22, it may be due to the insertion of abnormal loads. Remove the load. Insert manual bypass (SWMB), switch off and re-start the UPS. Exclude manual bypass Call the nearest service centre if this problem persists. Another possibility is a UPS input or output stage malfunction. Activate manual bypass (SWMB), switch off and re-start the UPS. Exclude manual bypass Contact the nearest service centre if this problem persists.
