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 c loth , to kee p it c lean ; th en apply so lder to th e t ip, to g ive it a wet look. This is called ‘ thinning’ and will
protect the tip, an d enab les you t o make good conn ections. When so lder ro lls of f th e tip, it ne eds clean ing.
• Thin raisin-core solder. Do not use any flux or grease.
• A diagonal cutter to trim excess wires. To avoid in jury wh en cutting ex cess leads, ho ld the lead so th ey
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 poss ible last m inu te manu al 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 solderjoints 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 !
AXIAL COMPONENTS ARE TAPED IN THE COR-
RECT MOUNTING SEQUENCE !

3. Determining the code
The four code digits are determined by fitting wire jumpers, see figure 1.0.

Attention : the wire jumpers that build the code must be as close
to the pcb as possible, because otherwise they will touch the
aluminium front panel!
The code sequence is determined by connecting the lines A,
respectively B, C and D to the connecting t erminals (keys 1 through 9)
at the inside of the pcb, where line A is the fi rst code, B the second
code and so on. The unused keys (normally 5) are connected to line N.

Construction
4. Preparation
Fit seven non insulated wires at the solder side of the pcb. These wires will be used later on for through
connection to the master module (see fig. 3.0).
Attention : the wires at the component side must be cut off as close to the pcb as possible.

1. Jumpers

on/off function of the key lock.
J1
Fit wire jumper J1 in case you intend to use the on/off function of the
key lock. If you don't fit this wire jumper, then, at the input of the code,
the code lock will only generate a pulse (in general this mode is used
with door locks).
"closed" contact or "open" contact .
NC or NO
Fit wire jumper NC if you intend to use the normally "closed" contact
of the relay, or wire jumper NO if you intend to use the normally "open" contact of the relay.

Pass two 2mm bolts through the front panel and
fix th em usi ng a nut.
Then pass a lock washer over the bolts followed by
the keyboard module. Take care that the LED is in the front panel.
ALU FRONT
Fig. 4
Normally, neither the LED nor the push buttons may pass through the front panel. The push buttons
must be flush with the front side.
Pass a 10mm distance tube over the two bolts, followed by the master module. Also take care that the
through connections pass through the master module.
Now fix both modules using two nuts, where after you can solder the through connections (pay attention
to short-circuits).

Test & usage
Test & usage
Connect a 9 to 15VDC or a 8 to 12VAC to the points V and GND. (V is the plus pole in the case of direct
current).
Put the front panel film next to the keyboard and enter the right code (in the case of a pulse out put this has
to be done within 5 seconds). If everything is going on well, now the relay should close and open again in
case pulse output mode has been selected. If however you have chosen for a constant switch position, then
you can cause the relay to open by entering a digit NOT belonging to the code digits.
Tip: should the opening tim e of the relay (in the case of the pulse output mode) be too short, fit a 22µ F
capacitor instead of C1 to change that time.
Building in
In case you use the key lock outside, it is advisable to mount it sunk, so that no water can soak in. For safety
you better first fix the code lock into the wall where aft er you stick the film to it, so that the fixation screws are
hidden "behind" the film.
Take care that, when sticking the film, the "LED WINDOW" corresponds with the hole in the aluminium.
