Pre-Start Sequence
If the car is properly adjusted and running well, but the floor to floor times are not as quick as
you would like, the Pre-Start Sequence parameters (Configuration > Drive > General tab) can
be used to allow the brake and/or motor to be energized while the doors are closing, thereby
allowing the elevator to leave the floor as soon after the doors are locked as possible.
The Pre-Start Sequence options
include:
“Allow machine to be energized”
• After doors are locked
• After door position monitor is
activated
• While doors are closing:
•with motor only
• with motor and partially
picked brake
•with motor and fully picked
brake
Regardless of the option chosen, the elevator is not allowed to move before the doors are locked
and the Speed pick delay 1 timer has elapsed.
The parameters that affect the Pre-Start Sequence options are found on the Configuration >
Brake > Control tab
The following pages include descriptions of each Pre-Start Sequence option and diagrams
showing the parameters that affect each option and the resulting sequence of operation.
Do not use Pre-Start Sequence options until drive control parameters have been
adjusted for no rollback and good control at zero speed.
