Check all the grounding and depending on the controller you are using moving the limit circuit to a 24V logic circuit would probably fix your issue. Really this just means you would run 24V through all of the limit switches to a 24V relay. The contact of the relay will then tie to the breakout board you are using. The relay would be activated when all is correct, so you would use COM and NC to go to the breakout board to generate the LIMIT error.
