33.1.4 Single Group Operation
When the system is running on emergency power, each car within a single car group is
individually recalled to a defined recall floor. Once all active cars have been recalled, a defined
number of cars (set by parameter 08-0186), are placed back into operation at the defined
emergency power speed. For the list of parameters, see the C4 Parameter List.
33.1.4.1 Number of Active Cars
A selected number of cars are set to operate during emergency power.
The following procedure describes how to set the number of active cars.
1. Navigate to MAIN MENU | SETUP | E–Power. See Figure 62.
2. From the E–POWER menu, scroll and select Number Active Cars.

33.1.5 Multiple Group Operation
Emergency power handles the car recalls and the number of cars placed into normal operation
across multiple interconnected groups. The multiple group operation works the same as the
single group during emergency power whereas a group of cars are given a priority assignment
(set by parameter 08-0129) and a limited number of cars per group (set by parameter 08-0186)
that can be activated for normal operation. Parameter 08-0230 sets the number of cars that
can be activated for normal operation across all groups. For the list of parameters, see the C4
Parameter List.
Car recalls, privileged mode cars and earthquake operations, and cars placed into operation are
coordinated between the groups. This coordination limits the number of active cars which can
be in motion. These operations are restricted based on the number of cars allowed to run.
