• At a minimum, recall to next floor: This option permits cars to be recalled to the nearest
floor to prevent entrapments if the Recall phase would instead be bypassed. The Recall
phase is bypassed if one of the cars is manually selected to run, Activate recall by the Auto
recall selection switch is selected but the Auto recall selection switch input is not active, or
Never recall is selected.
Emergency Power Run Based on the Number of cars that can be run at the same
time parameter, cars are selected to run as follows:
• Manual selection - cars are selected to run in the order they appear on the Run sequence
list as follows:
1. Cars with a Priority Run Request status (e.g. EMS phase 2, CFSS phase 2 and Fire Ser-
vice Phase II), that also have their Emergency power run input active.
2. Cars that have their Emergency power run input active.
•Automatic selection - If Always run is selected, or if Activate run by the Emergency
power auto run input is selected and the Emergency power auto run input is active, cars
are selected to run in the order they appear on the Run sequence list as follows:
3. Cars with a Priority Run Request status, e.g. EMS phase 2, CFSS phase 2 or Fire Service
Phase II.
4. If Last car to be recalled shall be the first car to run parameter is selected, that car is
chosen to run at this time, if it hasn’t already been selected.
5. All other cars.
Choose one of the following three parameters to determine the method used to activate auto-
matic selection of cars to run on emergency power.
• Activate run by the Emergency power auto run input: Cars are selected to run as indi-
cated in Automatic selection above.
• Always run: Cars are selected to run as indicated in Automatic selection above.
• Never run: Cars are not automatically selected to run on emergency power.
• Run Sequence: Cars are selected to run in the order in which they appear in this list. Select
a car and use the Up/Down buttons to order the list.
• Number of cars that can be run at the same time: Set the number of cars that may be run at
any one time, considering generator capabilities and elevator and other building demands.
Typically set to run one car.
• Run all manually selected cars: Caution! Checking this box will allow all manually selected
cars to run during the emergency power running phase. Please verify your building's gen-
erator capacity before activating this option.
• Last car to be recalled shall be the first car to run: The last recalled car is selected to run as
indicated in 4 above.
Power Transfer This phase, initiated by the activation of the “Power transfer input”,
indicates that commercial power is about to be restored. Cars that are moving on emergency
power are commanded to stop at the next available floor to avoid an emergency stop. No cars
are permitted to move until transfer to commercial power is completed.
If the Power transfer input is deactivated, and commercial power has not been restored, the sys-
tem will return to the Emergency Power phase it was operating in prior to the Power transfer
input being activated.
