Hello everyone,

Please let me know when we press start button on screen for Motor and Den-ester in auto and manual mode why it is not starting?, which points i have to check for input and output signals from drive.

And there is no error on screen.

Please refer both electrical drawings.

What is a Den-ester? What kind of machine is this? Who is the manufacturer?

Have you used your ear to determine if the contactor (or other relays) is being energized? Sure you want to stick your meter-probe/fingers near the phases?
