To reset the unintended movement the car has to be on hoistway access then go to menu 10 press enter go to 127 press enter make it a 1 and press enter. Some of the newer ones have a switch under the door bypass switches that can be slide in one direction to simulate hoistway access. Be sure to switch it back.

Release elevator from blocked state by dedicated reset of
the tripped safety device.
