Issues with debugging the Fisher 6030; I need expert help. I have to work overtime tomorrow, but I still don’t know where to start

That’s the situation right now: there is no movement at the midpoint; only when 20 ma is applied does the valve open fully. But if a current of less than 20 ma is applied, for example 19 ma, the valve closes completely immediately, and the feedback indicating the fully closed position shows 2.8 ma. Moreover, the screw used for manual adjustment also does not move in response to that feedback. What’s going on here? The handheld controller is for 475:'(
This situation is caused by improper settings of the locator; it is possible to use 475 communication for five-point verification and self-tuning, in order to check whether the linearity is correct. We have encountered this issue with the 6010 model as well in the past
I forgot to mention it – with the 475 model, I’m not sure if it’s due to an incorrect procedure or something else, but I can’t adjust it. On the interface for adjusting the amplifier, it’s specified that the output pressure should be between 50% and 70%, but it keeps showing 100%. No matter what I do, it doesn’t change. Is there any guide on how to adjust this setting for the 475 model? All the information online relates to the 375 model, and following those instructions doesn’t work either :(
There’s another issue: the command gate doesn’t move now! Giving 20 directly doesn’t cause any reaction at all. I just pressed the control buttons a few times, and also moved the feedback rod by hand (the feedback rod is a bit heavy, so it took some effort to move it). ) Have I broken something, or has the controller been misconfigured? I’m just a bit worried; I don’t think I’ve damaged anything though:'(:'(:'(
What error message appears when self-tuning doesn’t work?
It’s because it wasn’t installed properly; the installation angle of the feedback rod is incorrect. First, use the 475 controller to set the instrument mode to Out of Service. Then, from the Sensor Calibration menu, go to Travel Sensors Adjust. It is necessary to set the current reading of the travel sensors (Sensor Count) within its specified range (+600/-150) for the locator to function properly
When the feedback on the installation angle is incorrect, it can be corrected using 475; there’s really no need for physical adjustments. Is that really possible? Please answer
Display the current reading of the travel sensor (Sensor Count), adjust the feedback lever, and once the reading is within the range of –150 to +600, it is considered acceptable; at this point, self-calibration can be carried out
The range of -150 to 600 is quite large, isn’t it?
The numbers look large, but the actual size is very small
