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.
Make sure you have the right tools
-
A good quality soldering iron (25- 40W) 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 en-ables 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
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.
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 ONE AT A TIME ! 
Construction
Hook– up and use
Solder an AC cable to the SK1 pins (AC Power).
Solder the cables of the lampholder to the appropriate pins “SK2”(LOAD), use
always min. ø 0,75mm² cable.
As this kit is shipped to different countries, their is no AC plug supplied.
You will need to attach a plug that matches your electrical system. You can
adjust the ON/OFF time by turning the trimmer RV1 “OFF” and RV2 “ON”. The
ON/OFF LEDs indicate the LOAD status.
FThe connection cables should be equipped with a good strain relief when
mounted in a movable housing. FOptional you can mount a heatsink on TR1 (e.g.
ML73/25P) so that Max. power is 600W at 240VAC and 300W at 110VAC.
Inspect the complete assembly once more before applying power to the unit !
