Door Operation Menu Options
NUDGING? Enables Nudging Operation when doors are prevented from closing. During
Nudging Operation, controller will turn ON the NUDG output to signal the door operator to
close the doors at reduced speed. The NUDG output will stay ON for the amount of time the
Nudging Timer specifies and then cycle off for the same amount of time. This cycle will continue
until the doors have fully closed.
The NUDG output can also be used to activate a buzzer. The PHE (Photo Eye) input will be
ignored during nudging if the Stuck Photo Eye Protection option has been selected (see “STUCK
PHOTO EYE PROTECTION?” on page 5-22). A Safety Edge or Door Open Button input will
stop the doors from closing, but will not reopen the doors fully. Nudging Operation will begin
when the Nudging Timer elapses. The Nudging Timer starts when the regular door timer
elapses. The Nudging Timer is adjustable (see “NUDGING TIMER (Range: 10-240 Seconds)”
on page 5-26).
STUCK PHOTO EYE PROTECTION? When enabled, causes controller to ignore PHE
(Photo Eye) input and close the doors after the Nudging Timer elapses if the Nudging option is
selected or when the Time Out of Service Timer elapses, whichever comes first. If the Nudging
option is not selected, the PHE input will be ignored when the Time Out of Service Timer
elapses. (see “TIME OUT OF SERVICE TIMER (Range: 15-240 Seconds, or None)” on page 5-
26 for more details.)
If the Stuck Photo Eye Protection option is not selected, a PHE input that is stuck ON will keep
the doors open indefinitely.
SEQUENTIAL DOOR OPER. (F/R)? This option is available only if independent rear
doors are present. If this option is set to YES then the front and rear doors of the car do not
open at the same time. Whenever the controller receives a front and rear call to the same land-
ing, the car will, upon reaching that landing, first open the front doors and close them, then
open the rear doors and close them. The default is to open the front doors first unless the rear
doors have already started to open.
CAR
CALL CANCELS DOOR TIME? If this option is selected, pressing a car call but-
ton when the doors are fully open will cause the doors to start closing. There is one exception. If
the car is stopped at a floor, pressing the car call button for that same floor will not cause the
doors to close, but will cause the doors to reopen if they are in the process of closing.
NUDGING DURING FIRE PH. 1? If selected, the controller will turn ON the NUDG
output while the doors are closing during Fire Phase 1. The NUDG output signals the door oper-
ator to close the doors at reduced speed. This is useful for elevators that do not have mechanical
safety edges. During Fire Phase 1, all smoke sensitive reopening devices must be disabled. This
includes photo eyes and other devices that use infrared beams. If there are no other reopening
devices active, the doors should close at reduced speed.
RETIRING CAM OPTION? This option should be selected for elevators with retiring
cams. This option affects the car only when it is sitting at a floor. Without this option, the con-
troller will wait until the doors are closed and locked before it turns OFF the door close signal.
However, if the elevator has a retiring cam, the doors will not be locked until the retiring cam is
activated.
