Its not very clear on the motor instructions, you can see the open and close relays but its not clear which terminals relate to them. I would call the manufacturer to get the right info, you need to know which relay is normally open or normally closed and if the relays need to be momentary or maintained. On the DS2 side if you look at the three terminals marked relay, the terminal on the left is normally open (NO) the middle is common (COM) and the one on the right is normally closed (NC). hope this helps
