Vacuum ejector --> Aventics --> how to
Does someone knows how to control vacuum ejector with duet ?
I have ready one mosfet solution that will be installed between duet and ejector, but i can not find any schematics on how to connect this ejector.
I have two cables so one must be 24V power supply and other one is the control line + GND? But which is which and how to connect ?
This is the ejector that am using:
Any ideas ?
Looks like a fancy solenoid valve.
You can connect it to spare fan outputs (if the fan output has Vin and Vin is 24v) or a spare heater output. If using a heater output you should check if the ejector has a flyback diode or add that.
Both the fan and heater outputs have a 24v pin and a switched GND pin. You control it with M42 command

Thank you for reply.
Yes, it's fancy but very reliable and for professional use.
Do you know what valve pins should i use ?
In other words, where on this valve should i connect power supply and on which pin should i connect trigger line ?
sorry, not much info available
Where did you find this text, in which document ?
Am asking this because i have MNR 1834484253 connectors which i got in kit with all other stuff, so this must be it. I just dont know which valve connector should i use ( upper or lower one ) and if I need just one cable ( power supply ) ?
I have read the document on your link but it looks like that this is just for PE6 extender.
That was the only document on the page that had any relevant info on wiring, if its for the wrong part then idk.
Hi !. I got it working. The lower connector is for power supply and upper for "error management". When something is wrong, upper will trigger signal which can be interpreted as error code.
Where can i connect this error signal (GND and positive wire ) and how can i monitor it ?
I have also problems with pickup. Because the object has bumpy structure gripper does not fit 100% on surface. Do you know if its possible to use higher pressure ? At the time, am using 3 bar
