Here is the wiring for the timer for making the gate open at a time and close at a time: Power terminals 1 & 2 of timer to: 12 or 24 volts dc Terminal 4 to the common of the accessory terminals on the gate opener Terminal 5 to where an automatic exit device would go. Terminal 3 not used. The other thing to check is the display should show AUTO on the timer. If this is not you will need to toggle the Manual button until it is. When the gate is open the ON light should be illuminated. When the gate should be closed the light should be off. If it is not off then check the above to make sure it is on Auto and not ON; then check your programming to make sure it is scheduled to turn off properly. Lastly - Auto-reclose must be on in this configuration. That is what actually closes the gate - the timer simply delays the gate opener until the desired time. If you are trying to use it with auto-reclose off or for another purpose like turning off an accessory at a certain time or disabling the gate at a certain time let us know and we will explain a different way of hooking it up.
