What to do if LSIS SV-IS7 displays Over Current2?
If your LSIS Inverter shows an Over Current2 error, it could be due to a short-circuited output wiring. Check the output wiring. It might also indicate a fault with the electronic semiconductor (IGBT). In this case, do not operate the inverter and contact the retailer or LSIS Customer Support.
What to do if LSIS SV-IS7 displays Under Load?
If your LSIS Inverter displays an Under Load error, it could mean there is a motor-load connection problem, so replace the motor and inverter with lower capacity models. It could also mean that the set value for the underload level (PRT-29 and PRT-30) is less than the system’s minimum load, so increase the set value for the underload level.
How to troubleshoot a FAN Trip error on an LSIS Inverter?
If your LSIS Inverter displays a FAN Trip error, there may be a foreign object in the inverter vent where the fan is located, so remove any obstructions from the air inlet or outlet. The cooling fan might also need to be replaced, so replace the cooling fan.
