Hi I have a 3 phase 400v motor wired in star configuration it is controlled via a 3 pole 415v coil contactor which is switched simply via a stay put stop ... In for off Out for run.. ( Spanish design ) there is also a single phase fan connected between one phase and the star point of the motor. Got a number of these machines like this but this one.... sometimes when you release the stop button to start the motor it runs in reverse !!!!
In 50+ years in the industry Ive never seen this happen .... Any ideas?
Thanks
Dennis
