Guys would you please to share how to calibrate the IGV actuator on Carrier 19XR? much appreciated for your help
Shut the machine off by the stop switch, go to the service menu.Then go to "control test", then to "guide vane calibration".Hit select, it will ask if you want to proceed with guide vane calibration , select yes and it will drive fully open and record the voltage.It will let you know when it is finished, then hit exit and get back to the main screen.
Yes I have check and go through as per the bulletin said. on the other chiller the procedure is working properly and the machne is running fine now, but on the other chiller the IGV still not working.
I have jumper the J11 between X -2 the motor close, and between X- 3 the motor is open. I have replace the IO module with the working one swap from other chiller and the ICVC as well the same problem still happen.
So difficult deal with this control, anyone have any idea what next i should do.
The Potensiometer i have set to 0,25 V which shown on the screen.
