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 (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

* 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 !

Construction

The unit is equipped with a transient suppressor to reduce sparking. Normally, this suppressor is put over

the relay contacts. In some cases it might be necessary to put it on the load (eg. with very small loads).

Operation modes

SW1 OPERATION

MODE DESCRIPTION

Momentary

mode

The load will be switched on as long as the pushbutton is pressed.

Applications : doorbell, …

Toggle mode Push once to turn on, push again to turn off the load. Applications : put a virtually unlimited num-

ber of pushbuttons in parallel to control a light source or other device.

Start/stop

timer

Push to turn on. After pre-set time has elapsed, load will turn off. Push any time to turn off. Load

will turn off when pushbutton is held down and time elapses.

Applications : General timing. Hint : use as ‘Toggle mode’ with a very long delay time. This will

ensure lights will not remain on forever if forgotten to turn them off.

Staircase

timer

Push to turn on. After pre-set time has elapsed, load will turn off. A push during on-time will restart

timer and stretch on-time. Applications: staircases, basements, storage rooms, front door light-

ing, …

Dual-time

staircase

timer

A short push turns on with delay1* while a longer push turns on with delay2*. Repeated short/long

pushing during on-time will retrigger timer accordingly. Load will turn off when time elapses even

when pushbutton is held down.

Applications : same as above, but allows to select a longer time if necessary.

Operation modes

Non-retrigger-

able timer

Push to turn on. After pre-set time has elapsed, load will turn off. Pushing the button during on-time

has no effect. Load will turn off when pushbutton is held down and time elapses. Applications :

General timing.

Turn-on delay

Turn on delay starts when button is pushed. When time elapses, load is turned on until

button is released. Applications : Prevent cycling of light sources operated by a motion

detector on porches, front doors, driveways, …

Timer with

early re-trigger

prevention

turn on with delay1*. When time elapses, load is turned off and delay2* is enabled. Load

cannot be turned on again before delay2 elapses. Continuous pushing will not switch on the

load when delay2 elapses. Applications : Prohibit continuous operation of heating, airco, TV,

spa, …

Turn-off delay

Push to turn on load. When button is released, timer is started. When time elapses, load is

turned off. Repeated push during on-time restarts timer. Applications : Allow a pump or fan to

remain on for a while after a sensor detects pre-set level, to prevent cycling.

Interval timer

As long as the button is pushed, the load will be turned on during delay1*, and turned off during

delay2* Applications : Lawn sprinklers, pool pumps, compressor dehydration, ventilation, defrost-

ing,

Blinking circuit As long as the button is pushed, the load is turned on and off with a fixed frequency of 1Hz.

Applications : warning lights, buzzers, …
