Extra Features Menu Options
PI OUTPUT TYPE Choose either 1 WIRE PER FLOOR, BINARY BASE 1, BINARY BASE
0, GRAY CODE 1, or GRAY CODE 0 depending on the inputs required by the position indicator
and whether the floor count begins with a zero value or a one value.
FLOOR ENCODING INPUTS? If this option is selected, whenever the car is in a door
zone the computer checks the floor code inputs and corrects the P.I., if necessary. The code
inputs are provided by the landing system (refer to the Job Prints). Refer to R4, R3, R2 (see
“Spare Inputs Menu Options” on page 5-29).
ENCODE ALL FLOORS? This option is only available when the Floor Encoding option
is programmed to YES. This option indicates at what landing the Absolute Floor Encoding val-
ues begin. When set to YES, then every landing must have AFE code values, including the termi-
nal landings. When set to NO, then only intermediate landings must have AFE code values.
EMERGENCY POWER OPERATION?/EMERGENCY POWER RETURN
FLOOR If this option is selected, the controller will put the elevator into Emergency Power
Operation when the controller receives the Emergency Power Input (EPI) signal. During Phase
1 of Emergency Power Operation, the car will be moved to the emergency power return floor. In
a duplex controller, each car will be moved to the emergency power return floor, one at a time.
During Phase 2 of Emergency Power Operation, if the car's Emergency Power Run (EPRUN)
input is activated, the car will run normally. Otherwise, the car will remain at the emergency
power return floor and will not respond to any calls.
For a simplex controller, the car's EPRUN input is sometimes connected to a switch, so that the
input can be turned ON and OFF. For a duplex controller, both cars’ EPRUN inputs are usually
connected to a Run Selection switch. The position of this switch determines which car will run
during Phase 2 of Emergency Power Operation.
Often there is an AUTO position on the Run Selection switch connected to the AUTO input on
both controllers in a duplex. If the AUTO input is activated, then one car will be automatically
selected to run during Phase 2 of Emergency Power Operation. For example: If one car happens
to be out of service when the operation begins, the other car will be automatically selected to
run.
If the Emergency Power option is selected, then the appropriate spare inputs should be selected
also (see “Spare Inputs Menu Options” on page 5-29).
LIGHT LOAD WEIGHING? / LIGHT LOAD CAR CALL LIMIT This option is
only used when the Light Load Weigher Input is activated (see “Spare Inputs Menu Options” on
page 5-29, LLI spare input). To program this option, activate the LLI input. Then, set LIGHT
LOAD WEIGHING? to NO or press S to select the maximum number of car calls registered
before all the car calls are canceled. If S is pressed, the display will read LIGHT LOAD CAR
CALL LIMIT. Press S until the desired number is displayed.
PHOTO EYE ANTI-NUISANCE? / CONSEC STOPS W/O PHE LIMIT When
this option is ON, the car calls will cancel if the Photo Eye input has not been activated after a
programmed number of consecutive stops. The number of consecutive stops must be pro-
