How does the disengage work? If i grab the steering wheel and try to turn, the steering wheel is tight and the tractor lurches around. If I barely tap the wheel, it releases ok. The problem is that if I have a panic situation and try to grab and turn, it reacts very erratically.
Also is there a setting in the valve that slows down the turning? I have the max pwm turned up the whole way and it takes too long to get the wheels turned for u-turns. It did get to full turn, just takes too long to get there.
Hello guys, Sorry for my dummy questions, but I really don´t want to harm my only tractor…
So I have 3 questions.
Does have anybody NH tractor here and already installed the block? Because I can´t find any letters or plate on my orbitrol. Tractor is NH T6.165 tier 4A. But I can´t find out which port is which. I find out that the ports on the right are for piston, but on the left side I don´t know which is port T and which is P. Photo of orbitrol:
I guess that with 1 I don´t do anything am I right? But what it is?
Number 2 on pic is for adjusting pressure or something like that? What is best starting position for that?
Number 3 in pic is pressure sensor, adjustable with flat screwdriver, but also what is best starting position? Fully in and slowly out or in reverse? And this sensor is +5V, NC, right? And what digital pin is for encoder?
It is very easy! The most important thing is not to confuse the T and P ports, reverse connection may damage the hydraulic pump, so check carefully if it is correct.
The overflow valve you have marked (2) can be adjusted as follows:
After connecting everything, turn on the manual mode and “command” turn the wheels to the maximum angle, the PWM sent to the valve should then be above 100. Then, with the engine running, tighten the overflow valve until the wheels start to turn and pull to the set angle. Be careful not to be between the wheel and the body of the tractor, as there is a risk of crushing.
If you do that in an OC system, then almost all the oil will go through orbitrol even when autosteer is on.
I say almost , because there is some pressure left from the flow , and perhaps if oil is also used in gearbox for hi/lo.
The coils are without diodes, the citron does not require additional protection, I have never had a case of it being damaged. The coils of the 3/2 valves must be protected with a schotky diode, currently released all-in-may 1 boards have a built-in needed diode. If anyone wants, I can also add diodes to the solenoid plugs.
By tightening the sensor 3 adjustment screw clockwise, you increase the force required to disconnect the A.S. Run everything and try it, if AGO disconnects randomly, tighten the screw e.g. by 1 turn and check if it is good.
