So I just installed my first AOG system using a danfoss valve with Pwm control, but I cannot get any response from the danfoss when steering is engaged nothing happens. Is there anything I need to do on the PCB for danfoss?
Is danfoss selected in wizard?
Yes, it’s selected
Do you have a picture of all settings page?
What tractor is this on? Is there a lock valve that needs powering
You need a cytron to control the valve.
On my danfoss I don’t need the cytron. Do you know what your pressure reading is for override? With the 4-20 mv jumper in it may be reading too high?
Its on a Case STX440, the documentation says not to power the danfoss with the lock output pin just use the left and right pin.
Yes the pressure is not the issue i tested that. I just took a multimeter and test the wires going to the danfoss with the tractor off and AOG requesting to steer it was showing 190 pwm. So between GND and the pwm pin i got like 8 volts and between GND and the energize pin i got nothing shouldn’t i be getting something here?
Some info in that thread
Please post what version of board you have and how you have it wired currently.
Danfoss Gnd to AIO pin ?
Danfoss Us to AIO pin ?
Danfoss Udc to AIO pin?
Please also post a link to “the documentation” you were following.
I believe I have it figured out now, got some help in the telegram group. But this is how I currently have it wired I have the Us pin (pwm) connected to pin 5 on the ampseal and the Udc pin (energize) connected to pin 6 on the ampseal and the GND to GND. Seems like I need to put the Udc on pin 7 of the AIO. I’ll be trying this tomorrow.
I’m using V4.5 and below is the documentation I followed, I guess I was kind of confused with the ampseal pinout instructions.
Yup, you want pin 7 for lock on a v4.5
Prior versions had a jumper that could be set to use pin 6 for lock.
