What does it mean if my Riello UPS displays codes L01, L10, L38, L39, L40, or L41?
This can be caused by a fault in the temperature probe, UPS cooling system, main auxiliary power supply, or static bypass switch. Activate the maintenance bypass (SWMB), turn the UPS off and then on again. Exclude the maintenance bypass. If the problem persists, call your local service centre.
What to do if my Riello UPS displays codes A22, A23, A24, F23, L23, L24, or L25?
This can happen if the load applied to the Riello UPS is too high. Reduce the load to below the 100% threshold, or the user threshold if the codes A22, A23, or A24 are displayed.
What does it mean when my Riello MCT 10 display shows codes L26, L27, or L28?
This indicates a short circuit at the output of the Riello UPS. To resolve this: 1. Power off the UPS. 2. Disconnect all devices connected to the affected phase. 3. Power the UPS on again. 4. Reconnect the devices one by one to identify the faulty device.
What does the S06 code on my Riello MCT 10 display mean?
This issue occurs because of discharged batteries. You should wait for the batteries to recharge, or you can force power on from the System On menu.
Why is my Riello UPS running on battery when mains voltage is present?
The Riello UPS might be running on battery power due to a protective device upstream being activated. Reset the protective device, but first check for any overload or short circuit at the UPS output. Another cause may be that the input voltage is outside tolerance limits for mains operation. In this case, wait for the input mains voltage to return within the tolerance limits for the UPS to return automatically to mains operation.
What to do if my Riello UPS displays codes A26 or A27?
This can happen if the battery fuses are blown or the fuse holder isolators are open. Replace the fuses or close the isolators (SWBATT). If necessary, replace fuses with others of the same type.
What does it mean when my Riello MCT 10 display shows codes F42, F43, F44, L42, L43, or L44?
This can happen if the internal protection fuses on the batteries have blown. Call the nearest service centre.
What does it mean if my Riello UPS displays codes F19 or F20?
This can happen if there is a battery charger fault. Open the battery fuse holders (SWBATT), insert the maintenance bypass (SWMB) and shut down the UPS completely. Switch on again and if the fault persists, contact the nearest technical support centre.
Why won't my Riello MCT 10 start and shows codes A30, A32, A33, or A34?
If the Riello UPS displays codes A30, A32, A33, or A34 and will not start, it might be because the ambient temperature is below 0°C. Heat the environment, wait for the heat sink temperature to rise above 0°C, and then start up the UPS. Another cause may be a fault in the temperature probe on the heat sink. Activate the maintenance bypass (SWMB), turn the UPS off and on again and exclude the maintenance bypass. If the problem persists, call your local service centre.
What does C01 mean on my Riello MCT 10 display?
The code C01 on the Riello UPS display indicates that the jumper is missing from the R.E.P.O. connector (J13) or is not inserted correctly. Assemble the jumper or check that it is inserted correctly.
