Programmable LitePak Panels
FEATURES & APPLICATIONS
Timed Schedules
n
Use timed schedules to automatically
switch lights.
n
Remote switches permit occupant
ON/OFF switching.
* If switches are installed, ON schedules
should not be used, because the switches
permit the lights to be turned ON only
when needed. The OFF schedules ensure
lights are eventually switched OFF.
Flick Warn
n
Flick warn feature is used to war n
occupants that lights will be
switched OFF in 5 minutes.
Occupants can cancel the OFF by
switching the relay again (with
remote switch or override in panel).
Time-Out Mode
n
The time-out mode causes a
controller output to start an internal
timer when the relay is switched
ON. Upon time expiry, the output
switches the relay OFF.
n
The time-out mode can be enabled
and disabled with a time schedule.
Thus, switches work normally during
business hours and function with
time-out mode during closed hours.
Astronomical Control
n
With longitude, latitude, time zone
and date, the controller calculates
the sunset and sunrise times. An
output can be programmed to
switch at these calculated times.
n
An offset time (± 180 min) can be
entered to cause the switching to
occur sooner or later than actual
sunset and sunrise.
Photometric Control
n
Connecting WPS-5527K Photo
Sensor to the LitePak controller
permits digital entry of light levels.
Range of sensor: 0-6,500 fcandles
n
Each output of the controller can
have unique ON and OFF set points
for different requirements of a
lighting group.
Override Switching
n
To override circuits at the panel, use
manual on/off levers built into relays.
n
Install switch stations at locations
convenient to occupants.
n
To control individual circuits, connect
switch direct to relay. To control all
circuits, use group input on controller.
