View Full Version : A first with a 521

Using the 521 today I had the ground wire on the common and the red wire on the zone wire and on settings 3&4 it kicked on the valve but not on settings 1,2,&5. Don't recall ever having the 521 turn on a valve before.

I usually use earth ground when using a detector.

what are you talking about?

aren't you always supposed to ground with the earth on the black with that funky screw driver??

I always start that way but I was flushing out a difficult one with a secondary method.

After you track the wire path using the normal ground method you can then ground the zone wire and put the red on the common. This will cause them to cancel each other out. After you pass the valve the zone wire is attached to the null and sound will start up again.

There's plenty of juice in a detector, so solenoid operation is certainly possible. I can't envision a whole lot of benefit from not using earth ground, with some water to help it out, if necessary. For one thing, using two wires in a multiconductor cable might lead to a signal cancelling itself out. I always get a clarion blast when I find the solenoid.

Mind= blown....

very nice peter..i dont fully understand what your saying, but ill re read it a few times and let it sink in..

what do you mean by "ground the zone wire" hook black up to zone common and red to the wire in trace question?

That's cuz you manifold people are peons compared to us Texans when it comes to 521 usage skills.:p

The general idea in the locating process is for the wire to sort of become an antenna, radiating to your receiver. Grounding it out is something I don't need to do. I cannot recall a time I sent a signal into a solenoid, and couldn't hear its location.

now that we are talking about the 521, can someone please explain how to determine depth?

to find the depth you find the center of the null, turn the reciver 180 degrees from the wire path (mark the path), angle the reciever 45 degrees with the receiver tip on the ground until the bubble is in the circle, then back away from the path (the tone should then sound) until you hear the null again and the distace between the end of the receiver and your mark should be the depth.

We have the answer. That 45-degree trick gives you the depth.pwwwwwwwwwwwwwwwweeeeeeeez!Doesn't matter, they're too obscure to even show up on eBay (none to be seen today) so you aren't missing anything.

Only time I ever had a huge problem was when I had a solenoid that wasn't completely shorted out.....in a parking island...during a drought.....no water available.....

I blew the solenoid up w/ a neat little remote start trigger mechanism plugged into 120volts AC.....then the solenoid was toast....and I could find where the common AND the zone wire stopped...

Should have smelled it....

I once used a pigtail left over from a hardwired SL to do the same thing after fruitless hours of searching for a solenoid in a wooded area - worked great, but did have to put out small brush fire:dizzy:
