DESCRIPTION AND OPERATION
The LC8 Lighting Control Panel is an easy to use lighting controller intended
for applications where automated lighting control is required. Lighting control
can be configured to respond to scheduling, photocell input, astronomic
input, switch input and/or combinations of these. The LC8 is suitable for
controlling interior or exterior lighting, and can be configured with either
single pole single throw relays or double pole single throw relays for multi-
pole circuits. Configuration changes are easily made through the integrated
touch screen that is always accessible through the panel cover.
QUICK SETUP
The LC8 is designed to allow very flexible automated lighting control, yet can
be set up to do basic automatic control functions very simply. It is assumed
that your unit is installed and wired before using this Quick Setup. The steps
for basic control are as follows:
Interior Lighting
The following example provides quick setup instructions for assigning
interior lighting to a schedule. The basic steps are:
1. Set Time and Date.
2. Assign Relays to a Channel.
3. Set a Schedule.
4. Assign Channel to your Schedule.

Installing the Panel
The LC8-120/277 enclosure is designed for surface wall mounting. Attach
the enclosure to the wall using hardware appropriate for the wall type and
material (not included).
The relays for the LC8 are modular and may have shipped separately from
the enclosure. The relay modules are designed for DIN rail mounting. To
install the relay modules:
1. Place the module over the DIN rail with the terminal blocks to the right.
2. First, hook the terminal side of the module DIN rail track onto the DIN rail.
3. Then, lower the module and press down until the opposite side of the
module clicks to the DIN rail.
4. After the module is attached to the DIN rail, slide the module down the
DIN rail until it makes contact with the power supply module.
5. Carefully push the relay module against the power supply module
until the multi-pin connector on the relay module fully mates with the
matching connector on the power supply module.
6. Repeat this process for all relay modules that are to be installed in the
enclosure.
7. When properly installed, there should be approximately 1/16 inch
space between each module.
8. Connect the hot feed wire (120 or 277 volts) to the “L” terminal block
on the power supply module.

13
9. Connect the neutral feed wire to the “N” terminal block on the power
supply module.
10. Connect the building source supply earth ground wire to earthing
ground post. Use the other grounding post to bond power supply
module to earth ground.
CAUTION: This unit contains two earthing posts for
grounding. Only one dedicated post
shall be used for the building source supply ground and is not
to be used or shared with any
other conductors. The other postcan be used for earth
bonding of internal components.

2. The green LED on the power supply module will illuminate and remain lit.
3. Three red LEDs on the main PC board will illuminate and remain lit.
4. If any of the above conditions do not occur, refer to the
troubleshooting section, otherwise de-energize the feed circuit and
continue with the installation.
Wiring SPST Loads
1. Connect each load to the Load terminal on a relay module.
2. Connect the Line terminal for each relay to an appropriate source of
power to control the load.
3. Note that the LCSP-2 relay module contains two single pole relays
that are independently controlled by the panel. Thus, each LCSP-2
has two Input/Output terminal blocks.

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 voltage 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 relays. 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 pushbuttons or other controls provided except for a reset button
located above the capacitor inside the enclosure.

There are three states of a channel depending on the states of assigned
relays: ON, OFF and MIX (when there is a mixture of ON and OFF relays).
The relays that are assigned can be toggled on and off. By default, the
relays are assigned to the channels on a one-to-one basis. That is, relay
one to channel A, relay 2 to channel B, etc. See the section on Assign
Relays/Channel under Setup to change the default assignment of relays to
the channels. If channels are not assigned, a “---” will display.
