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 !

Connection

15. Connection & operation

Note : this kit operates on mains voltage and this may

present some hazards. Disconnect the kit from the mains

!

when working on the PCB.

A - Power supply :
Connect the device to the mains (110 - 240 Vac) through connec­tions L & N of connector SK1.

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

appropriate connection.

F The connection cables should be equipped with an appropri-

ate strain relief when mounted in a housing.

B - Connect the fan :

This kit enables you to switch on a fan together with the light.

G ATTENTION : check the wiring carefully when connecting to an

existing installation (see connection diagram p. 10).

— Connect the fan to output connector SK2.
— Connect Lx of connector SK1 to the cable linking the switch to

the light source in question (Ø1.5mm²).

— Connect the live (L) of connector SK1 with the live of the

mains.

— Connect the neutral (N) of connector SK1 to the neutral of the

mains.

Operation : The fan starts when the lights in the room are
switched on. After the lights have been extinguished, the fan will
continue its operation for 5 more minutes. This delay can be ad­justed by turning potentiometer RV1.

When the lights are turned on again during the deactivation delay,
the fan timer will simply restart. The deactivation delay will restart
after the lights are extinguished.

17. Mounting into the optional housing

This fan timer exactly fits into the box type G311 from Velleman
Components. Follow the assembly instructions below :

1. Drilling the holes :

— Mark the centre of the holes to be drilled on the front of the

bottom enclosure. (Fig. 1.0)

— You can drill the left hole with a Ø 7mm drill bit and the right

hole with a Ø 15mm bit.

Optional housing

2. Mounting :

Position the PCB in the bottom half of the enclosure. (Fig. 3.0)

G ATTENTION : Solder two wires onto the PCB instead of the

LED. The LED will be mounted on top of the enclosure later
on.

Mount the LED clip into the hole of the top
enclosure, together with the LED.
See Fig. 4.0

* LED clip (optional)
