How do I fix an F26 Start-up Prevent Fault code for a DG1 drive?

The startup prevent fault is due to a run command given to the drive with the damper startup function selected (P18.10). If the time out time on the damper timeout (P18.12) is met the drive will go into the start-up prevented fault. To determine the issue with this fault an input will come back to indicate the damper has closed so go into to monitor menu to verify the input is on or off, then go and check wiring and the damper circuit to verify things are operation properly.
