I am putting a timer relay in-line with a momentary pushbutton to hold power for 2-3 seconds. how exactly do i wire this. I am using 120 VAC to control a solenoid valve which raises a pneumatic piston up. I am using a Dayton time relay (grainger p/n: 5YZ86 on a base p/n: 5X852)
If i understand you correctly you want to push the button, release it and have the timer give power to the solenoid for 3 more seconds, correct? If this is the case you will need an off delay timer. On delay timers work like this. You push the button, power goes through the timer, at this point the timer starts counting, when the timer reaches its preset point,(3 seconds we'll say) the contacts change till the power to the timer goes off.
If you hook this up with an on-delay timer this is what will happen:
Push the button and release, the timer will tick as long as you hold the button down, till three seconds, then the solenoid will raise until you release the button.
With an off delay this will happen: push button , solenoid begins working, when button is released timer counts 3 seconds while solenoid is still working, then removes power to the solenoid.
The way you would wire the off-delay is like this:
Connect line side of your pushbutton(incoming power side),incoming power and terminal 1 on your base together. next connect the load side (outgoing power side) of your pushbutton and terminal 2 on your base together. Connect terminal 3 to the hot wire or terminal on your solenoid. Lastly connect terminal 7 the incoming neutral wire and the neutral wire or terminal of the solenoid together.
I am telling you how to wire it in my head, if you'll write back with some specifics such as what wire you will use, where your getting power from,what the solenoid current draw is and such i can get a little more detailed. maybe it will make more sense.
Also make sure the timer and pushbutton are rated to handle the solenoids running current. The timer appears to handle 10 amps im not sure what you pushbutton can handle. Also keep in mind the solenoid will operate for whatever time u set it to, after the button is released. There are other ways to do it but this would be the most economical way.
And of course turn the breaker off and test that it is off before working on the circuit. Write back with any problems.
