Operating Instruction

Light-Display-Module

for the

Light Control

Light@Night and Light-DEC

Light-Display-F Part-No.: 050032

>> finished module <<

At least one Light-Display-Module and one Light-Interface

(LI-LPT or LI-LAN) will build together the hardware for the PC-

Layout-Light Control Light@Night.

The connection of a Light-Display-Module to a Light-DEC-

Basis-Module will create the basic unit for the

Layout Light Control Light-DEC.

Light-Display-Modules contain 40 light outputs with a

possible current load of 0.5 Ampere on each output.

The lighting effects (neon lamps, flashing blue light, light

chains, traffic lights and many others) can be assigned to 40

outputs.

Suitable for analog and digital model railways.

This product is not a toy! Not suitable for children under 14 years of age! The kit

contains small parts, which should be kept away from children under 3! Improper

use will imply danger of injuring due to sharp edges and tips! Please store this

instruction carefully.

CE Part-No.:

146 40 18

Introduction/Safety instruction:

You have purchased the Light-Display-Module for the Light

Control Light@Night and Light-DEC for your model railway.

The Light-Display-Module is a high quality product that is

supplied within the assortment of Littfinski DatenTechnik (LDT).

We are wishing you having a good time using this product.

The finished module comes with 24 month warranty.

• Please read the following instructions carefully. Warranty will

expire due to damages caused by disregarding the operating

instructions. LDT will also not be liable for any consequential

damages caused by improper use or installation.

Connect the Light-Display-Module:

• Attention: Before starting the installation switch off the

drive voltage by pushing the stop button or disconnect

the main supply.

• The Light-Display-Modules contain a large capacitor

which has to be completely discharged before the Light-

Display-Module can be connected or disconnected.

Please wait a couple of minutes after switching off the

supply transformer before you connect or disconnect the

Light-Display-Module.

Connect the Light-Display-Module to the Light-Interface (LI-

LPT or LI-LAN), to the Light-DEC-Basic-Module or to the

already available Light-Power- or Light-Display-Modules via

the 10-poles pin-plug-bar.

The pin bar shall not be inserted in offset position to the

socket bar.

The modules are correct inserted whenever the pc-boards

are flash at the top and at the bottom. The pictures at the rear

side of this instruction show the correct position of the modules.

Light-Power- and Light-Display-Module do not need to be

connected directly to each other. It is as well possible to

connect the module via the “Kabel L@N” or via the screened

and therefore interference protected “Kabel Patch” (from

Light-Power Version 1.2 and Light-Display Version 1.7).

Light-Display-Modules contain 40 outputs with a maximum

load of 0.5 Ampere each. They are particular suitable for

switching light sources such as incandescent model railway

lamps or light emitting diodes (LED).

Voltage supply to the Display-Modules:

Each Light-Display-Module will get the voltage from a model

railway transformer via the clamp KL6.

The supply voltage can be between 10 and 18 Volt AC or

between 12 and 24 Volt DC.

If you use mainly light emitting diodes on your layout it is

possible that one 52VA transformer can supply more then

one Light-Display-Module. Picture 3 at the rear side of this

instruction shows how to arrange the supply of one

transformer to two Light–Display-Modules.

Please attend always to the same polarity (marked brown

and yellow) at the clamp KL6 of the connected Light-Display-

Module.

If you use incandescent lamps for illumination one 52VA

transformer can supply one Light-Display-Module. Also in

this case please attend always to the same polarity (marked

brown and yellow) at the clamp KL6 of the connected Light-

Display-Module (Picture 4 at the rear side of this instruction).

Connect the Illumination:

Each Light-Display-Module contains 40 outputs. Model

incandescent lamps can be directly connected. LED`s

require a serial resistor (about 4,7kOhm, depending to the

input voltage on KL6).

Each output can be loaded up to max. 0.5 Ampere. For

clamping a connection cable onto one of the 40 outputs please

press carefully down the white lever and insert the cable from

the top into the clamp.

If the Light-Display-Module will be supplied with AC-voltage is

the DC-voltage at the 40 outputs about (1,414 * input voltage)

– 1.4 Volt. An AC input voltage of e.g. 15 Volt (on KL6) will give

a DC-voltage of about 20 Volt at the outputs.

If the Light-Display will be supplied with DC voltage on KL6

the output DC voltage will be lower by about 1,4 Volt related

to the input voltage. The interrelation between input and output

voltage will be shown on table 1 at the rear side of this

instruction.

The common positive pole for all outputs is clamp KL7

(Picture 1 at the rear side).

The common positive pole contains three inputs which can

be loaded with 1 Ampere each. Distribute the common

positive connection of the lamps and LED`s evenly to the three

positive clamps KL7 (Picture 2 at the rear side).

Soldering instruction Provided you have no special experience in soldering electronic components please read first this soldering instruction before starting the job. Soldering has to be trained! • Never use additional fluxes for soldering electronic circuits which contain acids (e.g. zinc chloride or ammonium chloride). Those can destroy components and printed circuits when not washed off completely. • As soldering material only lead free soldering tin with a rosin core for fluxing should be used.
