(continuous transmission). When these kind of signals are present on the power line it is
possible that the Marmitek X-10 signals will not come through.
5. The mains do not stop at the front door of your home. Everything that is attached
to mains nearby your home can have influence on Marmitek X-10 signals (e.g. heavy
machinery). If you think that your system is influenced by devices out of your house, it is
advisable to install FD10 Phase Coupler/Filter on each phase entering the house. These filters
will block signals coming into or going out of your house, but will also match the impedance
for the mains. The FD10’s will not only filter but will also couple the phases (please see 1).
INTRODUCTION
Congratulations on your purchase of the LW12.
• The MicroModule can be installed behind conventional wall switches or into wall outlets
because of the extreme small size of the MicroModule (Minimum built-in depth 40 mm,
advised 50 mm). The MicroModule is also ideal for installation into light fixtures or for use
in areas with limited space such as rooms with lowered ceilings.
• Universal compatibility: No limitation in choosing brand, colour or type of any wall
switches and outlets. The LW12 can be used to switch and dim 230V light bulbs, 230V
halogen lamps and low-voltage halogen lamps with transformers ranging from 60 to 250
watts/230 volts.
This module can be activated using a momentary switch connected to it or using Marmitek X-
10 PLC signals. It can be operated using the following Marmitek X-10 signals: ON, Off, DIM,
BRIGHT and the optional Marmitek X-10 commands All Lights On/All Lights Off/All Units Off if
these are programmed. The unit will accept a momentary switch. The input for the switch is
connected to the phase (brown wire, 230V), the output of the switch is connected to input
"K" of the LW12 MicroModule. See figure A.
No Neutral (blue wire) has to be connected to the LW12 MicroModule, which means it can be
easily used instead of a normal switch, without additional wiring. The module is equipped
with softstart, softdim and a memory setting for the last dim level. When power has been
interrupted, the module will be in the OFF position. The
LW12 uses 1-way X-10 communication.
INSTALLATION
• Switch off appropriate mains fuse and master switch!
• Where present, take the wall switch out of the wall
box.
• Disconnect all wires from the switch.
• Connect the live (brown) and load wire (black) to the
terminals of the LW12 as described in figure A.
• Replace your normal make/break contact switch by a
momentary switch.
• Connect a load wire (brown) to the momentary
switch (CAUTION: In the interest of safety
and to make the device work properly, this load wire
