I have a problem from a lot of time, after the replacement of controller with elettroquadri + VF10 Tele..que. 2 vf10 was burn. The third is still alive. After the first we repalce the motor (new FIAM 1n). Now every 2 weeks the lift is down and the ovf10' error is "Ground fault". The insulated is ok. What can i do? Ottavio

I think there is problem with the calibration of one of the CTs. Try to find out the faulty CT.
