The cleanest and fastest way to stop the trips without losing your ADON learn is to physically disconnect the encoder's communication while you pull the rope.
1. Put the Car on Inspection: Place the controller on Machine Room Inspection (RDF / 270 switch down).
2. Power Down: Kill the main power to the controller.
3. Unplug the Encoder: Locate the ADON board and simply unplug the encoder connector (this is typically found at the XCT1 or XCT2 terminals, depending on your exact board revision).
4. Complete the Roping: Power the controller back up. You can now pull the new governor rope over the sheave. The sheave will spin, but because the ADON board is blind to the pulses, it won't trigger the UIM trip.
5. Restore: Once the rope is swapped and tensioned, kill the power one last time, plug the encoder back into the ADON board, and restore power.
While it might be tempting to change this parameter to "blind" the ADON board, do not change Parameter 5-21. Any changes made to the 5-series parameters (specifically 5-9, 5-10, and 5-21) will instantly wipe the ADON board's memory. If you change it, you will be forced to perform a complete ADON learn (shaft setup) from scratch once the new rope is on.
