Parker XA2 DOUT voltage pulsing?

Jon G 2 years ago in Expansion modules / XA2, XS2 updated by Gustav Widén (System support) 2 years ago 1

I have a system with a MD3 controlling a XA2 with several relays and solenoids controlled by DOUT channels when certain unrelated circuits are activated the DOUT power pulses continuously as long as the other circuit is activated.  before and after using this other circuit that does not run through the XA2 the unit operates as normal.

what would cause these outputs to pulse?  Their status even changes true/false in the MD3 monitor screen as they pulse. grounding has been confirmed and checked at different locations.


Resolved. due to insufficient voltage to the unit.
