Element Light always On - SSR Leakage?
 
Hi all -

I've read a few threads on this, but I still can't get it through my thick skull.

I have an "element on" pilot light on my control panel. I only want it to light when both:

A. PID is sending power *AND*
B. Element Relay is closed.

Basically, I want what Kal has.

It is a 120v pilot light. It is getting power from the black 120 output (black is SSR switched) of the element relay and neutral.

The way I have it wired, the light is always on if the Element Relay is closed.

I don't understand how I can fix this.

Do I need to buy a 240v pilot light?

Here is a cheesy picture of my current wiring diagram:

Please help me fix this.

Thanks!

I'm no electrician but you are feeding it live current at all times and providing neutral so it lights. You need to be on the other side (red in your diagram) to the pilot lamp. I think!

thanks sam....but I would think that the opposite of what you said would be true.

in my wiring, the SSR is switching the black 120 on and off. So hence, the light should be off at some points in time...unless the SSR is leaking current.

the red in my diagram is always hot when the relay is closed.

You need to put 240v lights in series with the element. If you look at Kal's panel that is how he has it wired. Your circuit will have a current loop from the hot in to the neutral, exactly how home wiring is done.

Thanks Bill...but doesn't Kal have the light wired in parallel with his element?

Yes, he does. I stand corrected there, but either way would work.

It's leakage.

so...why would a 240v light fix this?

if black hot is leaking current while SSR is "off" and red hot is flowing current as long as the relay is open, wouldn't the 240 light have the same problem?

can someone explain this in detail?

Have you tried it with the element plugged in? I use a 120v light. Mine will light from SSR leakage current until I plug in the element.

Really simple to explain, your 120Y is feeding it in serie with the element.

Fixing it is an other story, you'll have to find a 240V light or put a resitor in serie with your 120v(find the good size) and plug it in parallel with the element on 120Xto element and 120y to element.
