Leveling
• Leveling speed: Determines the speed at which the elevator will level into the floor (initial
approach prior to normal rate limited stop).
• Releveling speed: Determines the speed used during releveling, prior to normal rate lim-
ited stop. Releveling occurs after the car has reached a floor and subsequently is required
to relevel (direction enabled with ULM or DLM active). See also: Relevel distance and
Relevel dead zone distance.
• Leveling distance: Determines the distance from the final floor position at which the eleva-
tor operates at leveling speed.
• Releveling distance: The car must perform a re-level operation if it stops further than this
distance from the floor (with ULM or DLM active) or if, after stopping, moves further than
this distance from the floor due to load change.
Dead zone
an action may occur.
• Dead zone distance: The distance from the final floor position where the stop command is
issued (transition from leveling speed to normal rate limited stop) on the initial run to the
floor (i.e., leveling operation).
• Re-level dead zone distance: The distance from the final floor position where the stop
command is issued (transition from re-level speed to normal rate limited stop) during a
relevel operation.
Position Synchronization
switch, the encounter is reported to the controller. The controller can use the learned position
of the magnets or switch to update the current position reported by the position encoder. Posi-
tion Synchronization buttons allow you to force the controller to synchronize its position to
floor magnets or the bottom landing of the building (the controller 0.00 position).
• Terminal: Forces the controller to synchronize its position with a terminal landing. The
controller will use iLand reported position to choose to synchronize with an upper or lower
terminal landing. The car will travel at a rate halfway between Contract and Correction
Speed to the selected terminal. Upon reaching the first terminal switch, the car will decel-
erate to Correction Speed. At the final terminal switch, the car will decelerate to leveling
speed, synchronize its position, and return to normal operation. The on-screen Terminal
"LED" lights during synchronization.
• Floor: Forces the controller to synchronize its position with the current or nearest floor
magnets. The car will rise just enough to register the falling edge of the magnet-induced
signal, then resettle to the floor and synchronize its position. (The controller anticipates,
based on its logical position in the hoistway, that the signal should be encountered within
a calculated number of inches. If this calculation proves false, the elevator will stop at the
next floor.)
• Preset: Not implemented.
