What to do if Emerson Vilter VSS Air Compressor actuator cannot be calibrated because the button is held too long?
If the Emerson Air Compressor actuator cannot be calibrated, ensure you are not holding the push button down for more than ¾ second when calibrating. Each ¾ second the button is held down counts as another press. Depress the button quickly and then let go.
What to do if the calibrate button is stuck on Emerson Vilter VSS, and the actuator cannot be calibrated?
If the Emerson Air Compressor actuator cannot be calibrated, a possible cause is a stuck calibrate button. Attempt to free the stuck button.
Why the Emerson Vilter VSS Air Compressor actuator cannot be calibrated and the white calibrate wire is grounded?
If the Emerson Air Compressor actuator cannot be calibrated, it may be due to the white calibrate wire in the grey Turck cable being grounded. Tape the end of the white wire in the panel and ensure it cannot touch metal.
What causes Emerson Vilter VSS actuator calibration failure due to position sensor board issues?
If the Emerson Air Compressor actuator cannot be calibrated, it could be due to dirt or condensation on the position sensor boards causing them to malfunction. Clean the boards with an electronics cleaner or compressed air.
Why Emerson Vilter VSS actuator cannot be calibrated and there is dirt in optocoupler slots?
If the Emerson Air Compressor actuator cannot be calibrated, it may be because dirt or debris is blocking one or both optocoupler slots. Clean the optocoupler slots with a cotton swab and rubbing alcohol.
What to do if Emerson Vilter VSS Air Compressor actuator cannot be calibrated because of the photo-chopper fence?
If the Emerson Air Compressor actuator cannot be calibrated, it might be because the photo-chopper fence extends less than about half way into the optocoupler slots. Adjust the photo-chopper so that the fence extends further into the optocoupler slots. Make sure the motor brake operates freely and the photo-chopper will not contact the optocouplers when the shaft is pressed down.
