Relay Help

Does anyone know how exactly the relays work? I know that there is a forward and reverse value for each relay but what does setting both to different values do to the individual relay? Thanks in advance :yikes:

Be a little more specific and send me a pic if you can and i should be able to help. I programmed 3 relays for our arms along with limit sitches to stop them.

Take a look at page 2 of the User Guide to see if that helps any:
