Allow The Machine To Be Energized: While Doors Are Closing With Motor And Partially Picked Brake - MCi iControl User Manual

Allow the machine to be energized:
While doors are closing with motor and partially picked brake
This Pre-Start Sequence option allows the motor to be fully energized and the brake to be par-
tially energized while the doors are closing, so that when the doors become locked, the car can
begin moving as soon as the brake is fully picked. The diagram below shows the parameters that
affect this option and the resulting sequence of operation.
