Astronomic Function and Photocell Option
n
The LitePak controller unit has an astronomic function for dusk-to-
dawn lighting control applications. The latitudes and longitudes for
most North American cities are listed in the manual. This setting is
necessary for the Astronomic function to work properly.
n
The astro function permits offsets of up to 180 minutes from the
calculated time of sunset and sunrise. Thus, lights can be
switched before or after sunset and sunrise if desired.
n
The astro function can also be combined with the time function to
permit lights to be switched on at sunset, off at a later hour, on at
an early hour and off after sunrise.
n
Connecting a WPS-5527K photo sensor (optional) to the LitePak
controller permits precise numeric settings for the ON and the
OFF setpoints. Each output can have a unique setpoint.
n
Care must taken to install the sensor at a location that measures
natural and not artificial light. Usually best results are obtained by
pointing the sensor to the northern sky. Sensor range is from 0-
6,500 footcandles. Lower settings (less than 100 footcandles) are
used for dusk-to-dawn applications and higher settings are used
for daylighting applications (Ex: skylights).
Stand Alone Panel
n
Install LitePak panel near breaker panel and connect up to eight
circuits (for 8-relay models) or sixteen circuits (for 16-relay
models) to the panel (20A @120/277V lighting load rated relays).
The largest wire size that can be used is 10 AWG.
n
LitePak panels are pre-wired so that each relay (for 8-relay
models), or a set of 2 adjoining relays (for 16-relay models) is
connected to one of the 8 outputs of the controller. In this
configuration, each relay, or relay pair, can have its own program.
In applications where several relays are to be controlled by the
same program, connect the relay's red control wires to a single
output. Up to 4 relays can be controlled by an output of the
controller.
n
The LitePak panel permits manual override of the relays by:
1) The membrane keypad of the controller.
2) Manual on/off levers built into the relays.
n
Use the keypad and interactive graphic display menus to enter,
view and edit programs. In most cases the instruction manual
should not be necessary to make simple adjustments to
schedules, light levels and time settings.
L i t e P a k
CONNECTIONS
Optional Remote Switching
n
If accessing the LitePak panel for override switching is
inconvenient, install a remote switch station convenient to the
occupants.
n
All Douglas 2 wire relay switches are compatible. Indicating, non-
indicating and key operated switches are available. Up to 3
switches can be installed in a wall box to permit compact stations.
Off-white plastic and stainless steel cover plates are available.
n
Individual Switching:
Connect the red control wire from the switch to the relay. The
switch is connected in parallel to the controller output. Several
switches can be installed at the same or multiple locations
as required.
n
Group Switching:
The LitePak controller has one group switch input that can be
used to switch all or some of the outputs of the controller.
Expansion Panel(s)
n
To expand a system, install a LitePak expansion panel.
Expansion panels have no controller or transformer installed.
Only relays are installed and they are controlled by the panel
housing the controller.
n
An eleven (11) wire bus ensures that all connection
combinations are possible.
n
The outputs of a LitePak controller each can switch a maximum
of 4 relays. There are 8 outputs, thus a theoretical maximum of
32 relays can be controlled. If more than 24 relays are to be
controlled, it is recommended that full-sized, Douglas relay
panels be considered. Panels of up to 72 relay capacity are
available and they can be connected together to form even
larger systems.

Detailed Schematic Example
n The schematic shows an 8-relay LitePak installation that utilizes
all of the options possible. In addition, the switching groups are
altered slightly from the standard factory connections to illustrate
grouping several relays on an output.
n Relays 1,2,3 and 4 of the main panel are the factory connections.
Relays 5,6,7 and 8 of the main panel are all connected to
controller output #5 and they switch together.
n The expansion panel has 3 groups of relays that are switched by
controller outputs #1, #2 and #6. Note that 11 conductors connect
the expansion panel to the main panel even though all conductors
are not used. This permits all possible switching combinations and
permits switch stations to be connected to the expansion panel.
n The WPS-5527K photo sensor connects with 2 wires to the controller.
n The primary connection of the transformer (wiring not shown) is
wired for a 277V connection. If connecting 120V, connect the
120V wire of the transformer to the terminal block.
Caution: Do not connect 277V to the 120V wire of the transformer
as the over voltage will damage the LitePak controller.

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.
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.
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.
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).
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.
