ronfire Posted July 11, 2020 Report Share Posted July 11, 2020 When a Genesis controller is set for SSR do you have to change the cycle time or does it default to a set time? Will start to assemble my wall controller today and program it. Wish I could find an Current sensor to add to it that was not $34.00 usd. Can't find any listings for it in Canada or find the parts required to build one on Digi-Key. Link to comment Share on other sites More sharing options...
neilestrick Posted July 11, 2020 Report Share Posted July 11, 2020 I'd call Bartlett. Link to comment Share on other sites More sharing options...

Definitely call Bartlett, they may suggest additional modifications to parameters. The genesis model has a Specific programming point for SSR Which defaults to 500 milliseconds when set. Tech manual here about 2/3 of the way through settings, so you know how to get to the hidden menu function. https://binst.s3.amazonaws.com/uploads/manual/asset_path/224/Genesis_-_Technical_Manual.pdf Just to add any 50amp current transformer should work as long as you can get its output to 5volts. So a 50 amp core with 1 volt output would need 5 wraps of the load wire through it to register 5 volts at 50 amps actual draw. Link to comment Share on other sites More sharing options...

Lost me, I have seen the cores that work with 50 amps but don't understand how to make them work without the attached circuit board. Have only been able to find the current sensors for the Skutt and Bartlett controllers. Little over my knowledge base. Have seen the section how to set the controller for SSR but have not seen anything about the cycle time with SSR other than the 500 milliseconds, will give Bartlett a call on Monday Link to comment Share on other sites More sharing options...
ronfire Posted July 12, 2020 Author Report Share Posted July 12, 2020 So if I understand this right the Current transformer will developed output voltage when the power is sent down the monitored line. The more amps the more power output from the transformer. So if I chose the correct one (CR8420-1000) would produce 5.2 vac max at 50 amp, would this allow me to connect directly to the genesis controller? Cant be as simple as that? If so why do they sell the ones for the kilns with a circuit board attached? Link to comment Share on other sites More sharing options...

So if you have a transformer with 1volt output you could wrap 5 times to get 5 volt output like the attached diagram. This is turning into an electronics course. lol Link to comment Share on other sites More sharing options...

If so why do they sell the ones for the kilns with a circuit board attached? No idea why they do what they do. If their input is 0- 5 volts then any current coil with that output should work. If the factory model is attached to a circuit board and the board is powered from the kin, and not passive then maybe they are generating a 0-5 v output through a voltage divider of sorts to represent the Measured Current. Examining the input specs should reveal what they expect, but just buying one from them seems easiest actually than speculating. As a parameter it looks like the current sensor max amperage is a programmable number. Just get their stuff, no issues to figure out. Link to comment Share on other sites More sharing options...

ronfire Posted July 13, 2020 Author Report Share Posted July 13, 2020 Thanks Neil, learned something new in electronics. I like building stuff but am not an electronic wiz but manage the basics. I am in the process of building the wall controller, still need to connect to the power and the kiln but the box is done and mounted. Link to comment Share on other sites More sharing options...
