OPERATION GUIDE
Theory of Operation
The
LC8 lighting control panel is designed to automatically control interior or
exterior lighting
based on a weekly schedule, astronomic time calculation or input from an accessory photocell.
Automatic operation can be augmented or overridden through the use of accessory low volt-
age wall switches. Automatic operation is conveniently user defined by selecting an operating
mode scenario that will automatically combine the clock, astronomic and photocell operations
to produce the desired sequence of operation for each day of the week.
The LC8 supports the control of both single pole (120 or 277 volts) and double pole lighting
circuits (240, 208, or 480 volts) through the selection of either SPST or DPST relay modules.
Modules are available as either a single double pole relay or two independent single pole re-
lays. A maximum of 4 relay modules can be installed in the LC8 panel for a total of 8 circuits of
control. Input power to the LC8 panel can be supplied at either 120 or 277 volts.
All user interface with the LC8 is through the illuminated touch screen. There are no pushbut-
tons or other controls provided except for a reset button located above the battery inside the
enclosure.
