Moin and Hello,
The electronics seem to be the unloved child in the documentation.
I have a slightly more detailed wiring diagram including the startup
Function of D-Tec drawn. I hope it is helpful for one or the other.
Olaf
Very lovely, thanks for the good work!
Looks good. One possible change would be to wire the system so that fan/motor cannot turn on without having the heater switch turned on (series instead of parallel). The purpose would be to prevent cold extrusion.
Also, the fan is supposed to turn on with the motor, not the heater.

I adopted this in the v1.1 instructions.
Also, the motor terminal with the red dot is ground.
@jesse
I have added your suggestions as variant C,
and a minimum variant A.
I use Variant B (first post) with Heater Switch as Main Switch
and Motor Switch only to test purposes. I also add Relais
to protect the PID Controller Outputs (not shown in schematic)
Olaf
Your labels for variants B and C are reversed.
There's no center-off position on those switches.
There's no need for a second relay, the internal relay is rated for 1M cycles - that's about 10,000 hours of runtime, enough for 500kg of filament!
Hi Tim,
in with way the labels are reversed ?
The Switches in my kit (95) are on-off-on , with Center off Position.
I dont want to say the the pid controler are not got enough (sorry),
i only want to prevent to kill them by mistake e.g short circuit.
One question to the PID, are Power and Termocoupler Inputs galvanically isolated ?
Dont find information in the datashett.
By the way, first filament was extruded easily :-)
Bye Olaf
By labels I meant headings, but I looked at it too quickly - you are correct, I was wrong.
Also, you are correct about the switches - I was away from them and thinking about an earlier batch. They are definitely center-off.
Again, my apologies. I think maybe my brain needs a vacation - I'm losing my mind here!
I'm not sure about galvanic isolation, though I could find out if you'd like.
Hi Tim ,
I ask for galvanic Isolation to protect the PID Controller.
In another project, I have destroyed a controller
because 12V came indirectly to the Termocoupe (via Chassis)
For the moment I put Kaptontape between Brass an Thermocoupe
Have a nice Weekend

I'll let you know as soon as I know!
Thanks Olaf, this was very helpful.
I wired my machine according to the variant C schematic. When I power the circuit the PID turns on and I configure a target temperature. The nozzle heats up, and there is the red current temperature setting rises.
The motor and fan never seem to turn on, I'm not sure if this is a function of the PID (controlling the ALARM switch) a problem with the wiring or some configuration with the PID unit.
The PID makes a clicking sound and the OUT1 LED turns on and off (toggling power to the heating element, I guess?). No other LEDs turn on.
Has anyone else seen this? Any idea what I'm missing?
If the AL light doesn't come on, the controllers alarm is likely set wrong. You have to set a temperature to turn the motor on.
Thanks, that did it. You need to hold down the set button until "AL1" is displayed, then you can set a temp to control the alarm switch.

Aren't there instructions that explain this?
Ralph
There are instructions with the PID, but the English is fairly broken so its a bit of a challenge to figure out.
So no one has done a translation/English reprint?
Ralph
Add Minimum PID Settings
Nice!
Keep in mind, this is only for the Mypin variant.
Hi Tim,
If I knew on which pins of Sestos PID "alarm" is,
I could complete the schematics for these variants

Yup, I see what you mean.
Operation Procedures:
1/ Press SET key 2 second into the function mode, after return to the operation mode. If no any change
after 10 second automatic return.
2/ For temperature setting, press the UP or Down key change the value, after 10 second operate the new
setting.
3/ First operate the Auto adjustment, press AT key 2 second, SV display blink AT, finally into PID control
mode. Press the AT key 2 second to abandon Auto adjustment.
4/ If successful the first Auto adjustment, can not use AT key for Auto adjustment again. It need change
function setting Ctrl to 2 to operated again.
5/Auto adjustment needs from few second to few hour.
Suggestions:
1/ If use SSR or SCR for control part, setting control period prefer 4 second or shorter.
2/ If use relay for control part, setting control period prefer 20 second or longer for extend the relay life.
"the English is fairly broken" is an under statement.
But I guess others have gotten it to work so hopefully I'll manage.
Ralph
I'm with the instructions for the Sestos Controller.
Since I have no hardware ,once please
check pages 5-8
Olaf
I Would like to add that I have built SESTOS Variant C diagram Wiring ) Autostart, Cold extrusion not possible, Fan starts with Motor.
Followed the SESTOS instruction on the bottom of the BETA.pdf file you provided.
This wiring works great, one switch to turn on and everything is on Auto, good work.
I'm with the instructions for the Sestos Controller.
