CAUTION: The battery latches should always be locked, if not, the motor will crash into
the battery latch during retraction, preventing full retraction.
6. Adjust the door driver length to ensure the door fully closes when the pylon is
completely extended. The door should close firmly and be pulled into position,
deflecting the door inward into the fuselage (2-3mm) at the centre point.

7. Disconnect the door that was set up.
8. Install the other main door and adjust its door driver to ensure it fully closes as well as
per step 6.
9. Adjust the bell crank stop bolt to ensure the doors do not touch the fuselage during full
extension and also not touch the motor while the pylon is retracted or retracted.
Motor resolver calibration
The motor resolvers must be recalibrated if either the motor or motor controller were replaced.
Each motor is matched to the motor controller. Changing any one of these two components
creates a miss-match in settings, causing poor motor performance or could cause the motor
to not work at all. It is advisable to remove the propeller before calibration.
WARNING: If the resolver calibration is out, the motor could start rotating by itself. Be sure
to clear the propeller during the start-up of the system until the calibration has
been completed.
1. Switch off the RES main switch.
2. Install both HV batteries.
3. Boot the DCU into Maintenance mode.
