LCP128
Dimming & Switching Systems
System Overview
LCP128 is a combination dimming and switching
system that provides a complete lighting control
solution. The system consists of panels and control
station devices. An integrated astronomical time
clock provides system automation capability.
System Features
• 32 global lighting scenes and off.
• Connect up to 8 power panels for up to 128
dimmed/switched outputs.
• Connect up to 32 wallstations or control devices for
multiple points of control.
• Entire system is programmed using the LCD
controller mounted in the panel.
• Astronomical time clock provides automated selection
of lighting scenes.
• Works directly with incandescent, magnetic low
voltage, reverse-phase electronic low voltage, neon,
Lutron Tu-Wire
TM and switched load types.
• Works with DSI, DALI, and 0-10 V dimming ballasts
using Ten Volt Modules in the panel.
• Motor modules are also available.
• Panel may be surface or recess mounted.
• Feed-through or branch circuit breaker panels are
available.
• Panel is pre-wired and pre-tested.

Overview
Lighting control may be automated by using the
astronomical time clock integrated into the LCP128
controller. The controller has an LCD screen for easy
programming.
Features
• Controller LCD screens may be displayed in English,
Spanish, German, French, Portuguese, Dutch, and
Italian.
• LCD interface simplifies scene, time clock event, and
control station programming.
• Time clock events automatically recall presets at a
specific time of day or at an offset from sunrise or
sunset.
• Up to 500 total events are programmable within 7
daily schedules and 40 holiday schedules.
• Holiday schedules are programmable to run once or
repeat up to ninety days in a row.
• Two integrated Contact Closure Inputs provide an
interface with occupancy sensors or Building
Management Systems.
• Select system location from a built-in city database or
by entering latitude and longitude.
• Time clock is battery backed; time and event settings
are remembered even after power failures.

Class 2 (PELV) Wiring
The LCP128 system communicates to control stations using a Class 2 (PELV) low voltage link. Control
stations include wallstations, contact closure input and output devices, and RS232 interfaces.
Wire the Class 2 (PELV) link according to the following guidelines:
• Link must be daisy chained.
• Must run in separate trough from line (mains) voltage.
• Link must be less than 2000 ft. (600 m) long.
• Make wire connections inside the wallbox and LCP128 panel.
• Install Link Terminators (LT-1) at the start and end of the Class 2 (PELV) daisy-chained link.
• The order of controls on the control link is not important.
• Use Lutron GRX-CBL-46L cable or equivalent.
Maximum total length of the control link is 2,000 ft.
This distance is based on proper shielding of the
twisted/shielded pair, proper wire size, and the use of
link terminators (LT-1) at each end of the link. If
unapproved cable or smaller wire is used, control link
length must be de-rated according to the following
chart:

Note: Link Terminators (LT-1) are

LCP128 Class 2/PELV Link.
Notice! If Link Terminators (LT-1) are not
used or improper wiring topology is
employed, the system will not
communicate properly.

wire for 24 V (terminal 2) from
the Class 2 (PELV) link to the
control. Two #12 AWG wires
cannot both be terminated on

• Only connect the Drain/Shield
wire (bare copper) to terminal ‘D’
in LCP128 panels. Maintain the
shield throughout the link but do
not allow it to touch ground
