Car Start
The Car START feature controls when the car will respond to registered Hall Calls by
controlling the internal direction circuits. When the START circuit is energized the car will
immediately begin to respond to Hall Calls. There is a separate start circuit for the Low
Zone and the Upper Zone. A car will always respond to Car Calls immediately.
The START circuit is energized if ANY of the following conditions are true:
1.
The car is Next in that zone.
2.
The car is in the other zone, and is NOT next in that zone. (This means that both cars
are in the other zone, so the car that is not next in the other zone will be pulled into this
zone.)
3.
The call(s) in this zone have been registered for a preset time. (This allows the other
car to help in heavy traffic situations.)
4.
The car is not in normal group operation.
5.
The other car is not in normal group operation.
6.
The other car has a call behind it.
7.
Emergency Power is activated, and this car is assigned to run.
4.10.4
Homing
If there are no cars at the Main Dispatch landing, the "Next" car in the Low Zone will
home, or return, to the Main Dispatch Landing. If there is no "Next Car" in the Low Zone,
then the first available car will home to the Lobby. If desired, the "Free" car can be set up
to home to a specific (adjustable) landing in the upper zone, or to home to the Main
landing. (See the separate description on Feature Adjustments.)
A car will home if the following conditions have been met for 10 seconds:
1.
The car is in group operation (not on Inspection, Independent Service, Fire Service, Load
Weighing etc.).
2.
The Stop Switch is not thrown.
3.
The car is not stuck.
4.
