Assembly hints

1. Assembly (Skipping this can lead to troubles ! )

Ok, so we have your attention. These hints will help you to make this project success­ful. Read them carefully.

1.1 Make sure you have the right tools:

• A good quality soldering iron (25­40W) with a small tip.

• Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the
tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and en­ables you to make good connections. When solder rolls off the tip,
it needs cleaning.

• Thin raisin-core solder. Do not use

any flux or grease.

• A diagonal cutter to trim excess wires. To avoid injury

when cutting excess leads, hold the lead so they
cannot fly towards the eyes.

• Needle nose pliers, for bending leads, or to hold components in
place.

• Small blade and Phillips screwdrivers. A basic range is fine.

For some projects, a basic multi-meter is required, or

might be handy

1.2 Assembly Hints :

⇒ Make sure the skill level matches your experience, to avoid disappointments.
⇒ Follow the instructions carefully. Read and understand the entire step before you

perform each operation.

⇒ Perform the assembly in the correct order as stated in this manual
⇒ Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.
⇒ Values on the circuit diagram are subject to changes.
⇒ Values in this assembly guide are correct*
⇒ Use the check-boxes to mark your progress.
⇒ Please read the included information on safety and customer service

* Typographical inaccuracies excluded. Always look for possible last minute manual
updates, indicated as ‘NOTE’ on a separate leaflet.

1.3 Soldering Hints :

Mount the component against the PCB surface and carefully solder the
leads

Make sure the solder joints are cone-shaped and shiny

Trim excess leads as close as possible to the solder joint

AXIAL COMPONENTS ARE TAPED IN THE CORRECT

MOUNTING SEQUENCE !

REMOVE THEM FROM THE TAPE

Connection

17. Use

Connect this kit according to the wiring diagram. LED LD1 will light if the
operating voltage is correct. Take all necessary precautions to avoid
electroshocks when connecting cold-cathode fluorescent lamps : the

inverter ‘FLPS1’ uses a potentially life-th reatening voltage.

F This kit is available in various countries. Take care to use

an appropriate connection or adapter.

Selecting a light effect :
Push button SW1 ‘Effect select’ allows you to choose one of ten avail­able programmes. Hold SW1 to see which effect is currently selected :
the LED of that effect will light. The light effect will start running when you
release SW1. Press SW1 momentarily to select the next light effect.
SW2 enables you to activate or deactivate all channels. Press SW1 to
restart the selected light effect.

Adjust the speed of the running light with RV1

F The connection cables should be equipped with an appropri-

ate strain relief when mounted in a movable housing.

Random light effect :

Hold SW2 pressed before connecting the power supply (the
other light patterns shall not work!).

Number of connected channels :

Mount a jumper wire on the spot that matches the amount of
light channels you would like to use. This will make some light

!

effects adjust to the number of channels used.

Example : Mount a jumper wire on 5 CH if you wish to use 5

light channels.
