The Sprinkler Police Will Get You

Seems the water authority have been sending out their inspectors pre dawn and in the evening so if you are watering when you shouldn’t be then you might want to think twice. Its a hefty fine…

If you aren’t sure how to set your control then just give me a call.

Here’s the story

Orbit Controllers ‘Off Power’ symbol

Posted on 15th January 2012 in Controllers, solenoids, wiring

 

I got a call to look at this retic system where the control box was displaying the ‘off power’ water droplet symbol. (see the left side of the display)

I wasn’t sure what it meant or how it got there and the manual didn’t mention it. A brief google search suggested it may be the  box blowing a fuse and protecting itself against a faulty solenoid coil.

I called Scott at Total Eden and then he put me on to the tech heads at HR who weren’t totally sure either.

So I began to test it and discovered there was no voltage coming from any of the terminals. The fuse was intact and the battery was ok but the box just would not operate.

I attached a new control box as a test and it worked first time. The problem was in the box and whatever the source of the problem was, it had fried the whole box.

When the new one was installed I ran it thru the stations and it worked well on 1 & 2 but blew the fuse on station 3. Obviously this was the source of the previous problems and the coil needed replacing. As it turned out the whole solenoid was cactus and had to be replaced.

I repowered the Orbit box to see if the symbol might disappear but it was definitely a throwaway. So if you happen to see that symbol and your retic won’t work then chances are you will be looking for a new control box

 

Everything is off But My Solenoid is On

So what’s the deal when your retic box if switched to off and a solenoid is still receiving an electrical signal and is stuck open?

Honestly I have no idea…

But its happened to me 3 times now and today I was able to resolve it.

The first two times were with Hunter EC 2 station control boxes and I couldn’t find a solution and ended up changing the box over. It was a faulty box, but this time I had another 3 terminals to test before doing a swap. On terminals 4 & 5 the solenoid stuck open (there was negilible voltage coming from the terminals (4V) but when I switched the wires to terminal 6 the problem went away.

I have no idea what was going on but on each occasion it has been a Hunter control box that has been the problem. Today was a brand new X Core.

So if you find a solenoid stuck open despite there being no voltage going to it maybe you’re not crazy. Maybe its the control box doing some crazy stuff
