Plug in the red and blue power wiring to the red and
blue power wiring from the transformer using the
provided Molex connection as shown in Figure 4. The
controller display should power up and display the

Relay Override Operation
The LiteKeeper® has a means of overriding relays on or
off without the need of the logic board in place. There is
an all enclosure override switch located at the bottom of
the enclosure. It is possible to control lighting loads and
override programming using this override mechanism
without the logic board being in place.
The Standard Override Card is located at the bottom of the
enclosure. If this switch is moved to the ALL ON or ALL
OFF position, all relays in the enclosure will be energized or
de-energized as long as the switch is in the ALL ON or ALL
OFF position. The ON or OFF state is maintained regardless
of programmed state. In order for relays to run programmed
scheduling the hardware override switch must be in the
AUTO or center position.

LED Operation
The LiteKeeper® has LED indicators for system status
monitoring. These will be discussed in two sections,
including LiteKeeper® status LEDs and relay status LEDs.
LiteKeeper® Status LEDs
There are two (2) system status LEDs that are located in
the upper left corner of the LiteKeeper®. There are two
additional LEDs located in top middle of the board next to
the ribbon cable connector that diagnose Digita® switch
communications. Please refer to Figure 5 for location of
these status LEDs. These status LEDs will indicate proper
operation or potential problems with the LiteKeeper®.
normal operation includes the following LED states.
Status LED:
The status LED will flash ON and OFF
continuously under normal operation. The LED is an
indication of microprocessor health. If the LED is ON or
OFF all the time, please use the soft reset button on the
controller. If the LED does not resume normal flashing
state, contact
Technical Support.
Power LED:
The POWER LED indicates that the
LiteKeeper® is getting the proper expected voltage from
the transformer. If this LED is not lit, there is a problem
with power to the board. Please contact Technical Support
for further details.
Digita® Switch LEDs:
These LEDs, labeled CAN-TX and
CAN-RX, will flash when Digita® Switch information is being
passed back and forth between the Digita® Switch Gateway
and the LiteKeeper®. The CAN-RX LED flashes when the
controller is receiving data from the Digita® Switch BUS.
The CAN-TX LED flashes when the controller is sending
data to the Digita® Switch BUS.
