Heating Element Control

[peanutaxis]

Thanks,

Yeah I tried a voltmeter on mine and it didn't work. Don't think I'll bother trying an ammeter then.

Burst fire controller might find an ammeter more useful.

Not true. If you have ever hooked an ammeter up to a burst fire controller it dances around alot and will not give you a clear figure. Where as with phase angle control, the needle will go up and down smoothly

OMG...I've just returned to this forum from many months away and can't believe this thread is still going

Got me pissin in my pants. I haven't been over all the new pages but for those of you who have....is there some kind of repetition going on?

This thread is sending me ........

It sure beats 50 repetitive topics scattered throughout the forums...

Well, I think I indicated that possibility and the modifying factor that it depends on the rate of burst fire and the type of ammeter you use. Moving iron for example would have a little more inertial mass than moving coil.

I know it all works smoothly on phase angle. Another reason they are my personal preference. It's just not needed as the voltmeter does a fine job for dialling in.

If a volt meter does nothing for him and he has it connected right then he probably has a burst fire module. So an ammeter is his only hope. yes it is unlikely to provide a clear steady reading except in the unlikely (more expensive unless you make it yourself)event he has one that is firing at twice mains frequency or at least mains frequency. The Suntronic one linked, with a firing rate of one second, would jump wildly for example. 100 to 120 times a second and you are doing better.

Just finished wiring my 240V 5500W but I am having problems with it. Simply, when I plug it in, it doesn't work and the ammeter isn't reading any Amps. I don't think that I wired it wrong, but here is a diagram of what I did just in case. How does it look? See any problems?

[MuleKicker]

are you using a psr25 or a chineese module? Is the amp meter rated for amps ac? What is the pot rated at? and what pot is the module calling for? If you have an ohm meter, do a sweep on the pot. If that checks out, you have a bad module. (provided it is wired up exactly as you have pictured)

[MisterSteve124]

Everything is wired up exactly as pictured. The PSR is a chinese module for 40A, the pot is rated for 2 W, the ammeter is AC, and I'm not sure what you mean by what mode is the pot calling for. I was having trouble figuring out what way to wire it. I think I did legs 1 and 2.

For testing purposes, try to simplify things by bypassing both the switch and ammeter... And remember that you have to have the heating element in the circuit for testing as the elements resistance is required for the module to trigger... You can also jump across terminals 3 & 4 which should cause the module to apply full power to the element... That will leave either the module or the element as the culprit if no heat is generated... And always make sure the element is submerged in water as it only takes seconds to fry it in thin air...

[MisterSteve124]

Yes I did have the element hooked up and fully submerged when testing, but i will try bypassing both the ammeter and switch and the potentiometer to try and pinpoint the problem. Ill give it a go tonight and let you know. Thanks

No luck testing it today. After trying about everything I decided to pull out the multi meter. When I tested a hot and ground it was about 100V AC and when I tried the other it was the same. But when I tried both hot it said like 1. What is this about? I can't figure out if its something wrong with my breaker, or my heating element. Any ideas?
