Fluid bed roaster cooling stage Artisan+TC4
iPa
How do you manage cooling stage with Artisan and fluid bed roaster ?
I mean there is no Drop stage, but need to power off heater and adjust fan speed to cool down as quick as possible.
Add some specific button ?
Is it possible to set more than one action with a single button (heater OFF, fan 80%) ?
Alarm Actions ?
Thank you
 
renatoa
Create a button with a serial command action OT1;0 for the heater, followed by OT2;80 for the fan
This is for a TC4 scenario, for other devices the commands are different.

I've tried to send more than one command with a "Serial command" button without success, probably not using the correct separator between commands.
But Button mode Multiple events works well.

I saw in the list of serial commands:

PID,STOP
Turns off the PID and heater. Sets fan to auto cool setting as defined in user.h. Can be used at end of roast. Response from TC4 device is "# PID Roast Stop"


I could use this command to end the roast, even better no?

But I suppose that Artisan would sent it too, but when it does, on press DROP button ?

Nope, Artisan don't send anything to TC4 other than some init commands and temperature reading command.
Any event related commands should be added by the user in the Events dialog.
Attached you have an example of an Events dialog really stuffed with commands, but they aren't mandatory for a typical TC4 setup.

PID;STOP control of the fan depends on other config values.
Is PHASE_ANGLE_CONTROL defined? How is the fan connected/controlled ?

Thank you, that was the missing part !

My config :
i84.servimg.com/u/f84/20/23/21/77/ef31ab10.jpg
Yes PHASE_ANGLE_CONTROL is defined for this config
 
renatoa
If PAC defined, then PID;STOP will call outIO2 for the fan control, thus a DC fan connected to IO3 will not react to this command.
You need CONFIG_PAC2_IO3FAN in this case.
