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.
What does NTC Open mean on my LSIS Inverter?
If your LSIS Inverter displays an NTC Open error, the ambient temperature might be too low, so keep the ambient temperature above 10?. It could also mean there is a fault with the internal temperature sensor. In this case, contact the retailer or LSIS Customer Support.
What to do if LSIS SV-IS7 Inverter displays IP54 FAN Trip?
If your LSIS Inverter shows an IP54 FAN Trip error, the fan connector might not be connected, so connect the fan connector. The power connector for the internal fan PCB board might also be disconnected, so connect it. Additionally, the cooling fan might need replacement, so replace the cooling fan.
What does No Motor Trip mean on my LSIS SV-IS7 Inverter?
If your LSIS Inverter displays a No Motor Trip error, the motor might not be connected to the inverter output, so check the wiring connections. It could also mean that the current level for trip detection is not set properly, so check the values of both BAS-13 (Rated current) and PRT-32 (No Motor Level).
