Hello, have a 330A with intermitant ETSL fault. Purchased sensors from Adam's. Adams had 2 different part numbers for the switches. One NO and one NC. Current setup at job has 2 NO switches. Can someone confirm which is correct setup?

Thanks.

Hi, the serial number on the sensor would indicate which is needed. It’s either a NPN or PNP
