Solenoid Problem?

[paulc]

Since I installed my D-D CO2 kit I have had problems with it shutting off at the end of the day. Yesterday I thought it was the timer switch so I tested it and found out that I had pressed the random switch on the timer. So i turned that off and plugged the timer switch back in. Yesterday evening the solenoid failed to turn off again. The timer switch went off fine (the red led went off) but CO2 was still being produced. This was not residual co2. I do have another timer I can test but I don't think its that. Reason being is that yesterday I tested the timer and solenoid. I timed it to go on and then off five minutes later. Did this several times but still the solenoid did not turn off at the end of the evening.

Now, could this be a pressure thing? My CO2 pressure being supplied to the diffuser was 0.5 bar and I read on a forum that a solenoid relies on pressure to help make the seal. Any thoughts on this?

I have since upped my pressure to 1 bar and have switched out the timer to a different one.

0.5 bar is really low...Pressurised cylinders should be at working pressure of around 1.5-2 bar. I think this may be your problem. At the moment mine are working @ 2.5 bar as i'm using atomisers, and theses need a little more pressure.

Thanks Ian as always

I'll up the pressure and see what happens tonight.

Just a quick update - the move from 0.5 bar to 1 bar did the trick

Hi,

Sorry to jump oin the end of this thread, but it saved me cluttering up the board with a similar question.

i believe i have the same kit as you (LINK) Currently mine is sitting at just under 5 Bar. Is this too much? should i reduce it to 2?

i have been having trouble getting the final tweaking done (its either too much or off) would this be the cause?

Thanks
