Relays not functioning

When powered from the nano the relays open a normally closed circuit. Even in manual cannot close circuit again. Trying causes relay to cycle on and off. Sprayer functions as normal with relays unpowered.
Using version 5.1.3, 8 relay control board for 5 sections. Have tried control on a single relay with no difference. Currently nano is the only power source. Any suggestions?


Did you apply "invert relay " in configuration , arduino , hydraulic lift?

Tried that it causes the relays to trip and then reset constantly??

Try powering it with a buck convertor, in simulator does it work?
