Hello,
As I age I just cannot work things out like I used to so please help me if you can.
I have 2 x 12 volt 3 way valves that have 2 wires each. To operate each way requires the power to be reversed - same as you would to forward and reverse a motor to run in either direction. These valves cannot be energized all the time as that would burn them out and they only need 5 second run time to turn either way by having their wires reversed.
Both valves are to operate at the same time.
I have 2 x timer relays (SPDT) that are set to 5 seconds so when power is supplied to the coil the relay will switch on for 5 seconds and then automatically switch off.
My plan is to use one timer relay to turn the valves one way and the other timer to reverse the wires and turn the valves back again.
I need a diagram of how to wire this please as my brain isn't doing a good job of working it out.
I think the fact that the valves can only receive power for 5 seconds is confusing the issue.
By the way, I do have other regular relays available to use also if needed.
Please help sort this out for me, your help would be greatly appreciated.
Many Thanks,
Les
