VLT® HVAC Drive FC 102
Problem with changing the value of a parameter
Some parameters cannot be adjusted while the drive is running, and it may also be password protected.
If your display shows "NOT WHILE RUNNING," first press the off button and allow the drive to come to a complete stop before changing the data.
If you see an error message or "READY ONLY" after pressing OK, it means that the data cannot be changed.
