JLD 634 HELP!
Posted: Mon Jun 23, 2014 1:27 pm
Hello all (especially Marco!)
I've read through the JLD 634 topics here, and still have questions, including:
Making the SSR output actually ride on and off rather than vary voltage (it leaves the relays on, even when PV is greater than SV).
Using multiple program ranges (if we have two Ramp/Soak profiles, do we need two controllers?)
Using it as a Thermostat for running our oven when not running a program.
I currently have a program set, and it will run through the way we want it to, changing the SV according to time, but the relays remain energised even when PV is over SV.
We will not be using lights or alarms, but have used the J1 to make the thing work at all to get started, with the alarm function as our output, so I'll be rewiring as soon as I can get the SSR to run our relays.
Thanks! I know it's vague, so I'll try to explain what we have so far:
JLD 634
Relays
Heating elements
Oven
We would like to be able to set the SV without a password (if possible) to 100F, 120F, 180F throughout the day on a regular basis as production dictates.
The Ramp/Soak program I've written, which works as far as I can tell, goes from 70F (ambient) to 85, 100, etc. every 15 minutes. It holds at 130F for an hour, etc. It takes 15 steps to do what we need, and returns to step one to repeat.
Could I start a different program at step 20, and make a similar loop or pause? How would I go directly to that program step to run that program when we need it?
The instructions assume you're familiar with PIDs...
I want to write a simpler program to AutoTune to our oven and elements.
