Good Afternoon,
Our GOT1000 HMI was wired incorrectly when the vendor installed them. +24V was on ground and ground to +24V post. Everything was working fine until our Ionization system was being tested/calibrated with a 1000V charge plate placed in the tool. Then the GOT1000 HMI display went blank and no indication lights were lite on the front. I swapped the wires and the HMI works fine now. It's understandable that it faulted when the ION systems were being checked due to the polarity problem caused by the wrong wiring.
The question I have for anyone who might know is, why was the GOT1000 HMI working at all with the wiring wrong like is was?
Thank You,
Webby
