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 o r c loth , to ke ep it c lean ; th en apply so lder to th e t ip, to g ive it a wet look. This is called ‘ thinning’ an d w ill

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 leaf let.

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 !

Configuration

17. Configuration

At power-on, LD1 will flash a # of times, hereby indicating that the unit is operational. Next, LD4 will turn-on.
At first power-on, the unit will respond to channel(1)/button(1) of the K8058/VM118R transmitter. Make sure the transmitter
buttons are configured as 'pulse' (check your K8058/VM118R manual).

18. To learn a remote(button):

1. Hold 'setup'-button. LD1 turns on.

2. Hold a remote button (1..8)

3. LD4 will light when the button has been stored

4. Release all buttons
Repeat steps 1 trough 4 to learn other remote buttons or remotes.

 31 transmitters or transmitter-buttons can be stored.
 If the memory is full, both LD1 and LD4 will flash rapidly.

19. To remove all stored remotes from memory and to return to factory defaults

1. Turn off the power.

2. Hold 'setup'-button.

3. Turn on power. LD1 and LD4 will start flashing

4. Release 'setup' when LD1 and LD4 stop flashing

 This process takes about 10 seconds.
 If the button is released before the leds stop flashing, the memory will not be cleared.
 The unit will now respond to the default code only.

20. Configuration of left and right relay output

1. Push 'setup'-button repeatedly to configure either left relay (LD2 lights) or right relay
(LD3 lights).

2. Confirm your selection with a long push (LD4 flashes 3 times). The selected relay will
remain ON.

3. Push 'setup'-button a number of times, depending on the desired mode (see table). At
each press, LD1 will flash a # of times, indicating the current mode.

4. Confirm with a long push (LD4 flashes 3 times). The selected relay will turn off and the
unit is ready for use.

 The unit will return to normal operation when left idle for 10s. The current mode will not

be changed.

If necessary, repeat sequence for the remaining channel.

Factory defaults: left relay-output: 0.5s timer right relay-output: 1h timer

21. Use

Pressing a transmitter button will operate both outputs simultaniously.
Each relay will behave according to the selected mode.
In '0.5s timer'-mode, the relay will remain on for as long as the remote button is held.
In 'ON/OFF'-mode, the relay will toggle between ON and OFF every time the remote button is pushed.
