Customer Question
I'm trying to wire...

I'm trying to wire a CP3 exit probe 2 mi LiftMaster la500 with an expansion board

Contractor's Assistant: I'll do all I can to help. How long have you been dealing with this?

I just got it out the package this evening and looked in the control box I wired up my exit loops and had no problem

Contractor's Assistant: Do you plan on doing the work yourself?

Yes

Contractor's Assistant: Anything else we should know to help you best?

Not that I can think of I have 3 wires black red and white and green but I'm pretty sure if I understand the wiring diagram the green is not necessary and the red I know goes to the 24 volt Supply

Contractor's Assistant: How old is the system in question? And have you consulted an electrician yet?

It's brand new I wired everything myself and it works fine
