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 (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 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

Assembly hints

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

1.3 Soldering Hints :

1- Mount the component against the PCB

surface and carefully solder the leads

2- Make sure the solder joints are cone-shaped and shiny

3- Trim excess leads as close as possible to the solder joint

REMOVE THEM FROM THE TAPE ONE AT A TIME !

DO NOT BLINDLY FOLLOW THE ORDER OF

THE COMPONENTS ONTO THE TAPE.

ALWAYS CHECK THEIR VALUE ON THE

PARTS LIST!

Test & connection

19. Test and connection

The card uses a separate supply for the relays and one for the board microcontroller.

Test 1:

• Connect a power supply of 9 to 10Vac or 12 to 14Vdc (minimum 500mA).

• The power LED should turn on.

• The USB power LED will also turn on (indicating that the microprocessor power

is ON).

• Push the buttons and the relays should activate.

Test 2:

• Disconnect the power supply.

• Connect the USB port to the PC.

• The USB power LED should turn on.

• Pressing the buttons will make the output indicator LEDs turn on, but the relays

will not activate.

Now the card can be used with all connections. It is possible to power the card through USB only, but the relays will not activate. The relay indicator LEDs will work fine. This mode can be used for software testing.
