laser4000 mac valve

[bones]

What would make a mac valve energize on and off by itself?
It's not not leaking but energizing 24v .No cars in the bay or waiting to enter. I do not see any output lights in jo going on and off when the valve is going on and off????

I would check the voltage when you hear it pop. check it on the output y20. If you are geeting power change the relay. If not..

The mac valve has a little white button on the side of it,if you push it your valve will pop over..there could be something going on there also. You may have a button that is stuck in a little. You may need to replace the mac valve.

check the connections in the j box on the pump stand that they are not shorting out with maybe a weep cycle or something.

Also one other thing. check for water in the control box on the pumpstand.

The only other thing that comes to mind is you are losing air pressure to the valve. Is everything ok with the air compressor?( long shot on this idea)
