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.

Set-up 15. set - up The K8050 features 4 operating modes, selectable with diodes D16 and D17. 1) 2) 3) 4) 15 independent outputs. 15 rotary outputs 7 independent outputs & 8 rotary outputs. 7 rotary outputs & 8 rotary outputs (independent from each other). MODE D16 D17 1 Not mounted Not mounted 2 Not mounted Mounted 3 Mounted Not mounted 4 Mounted Mounted Momentary (push button-) function : Hold the key to activate the output and release the key to deactivate it.
Set-up For each output : Diode type: 1N4148 Check the polarity ! CATHODE D... If a momentary output is needed, DO NOT mount a diode for the corresponding output D1 to D15. If a toggle output is needed, MOUNT a diode for the corresponding output D1 to D15. ADDRESS SELECTION Different possibilities in conjunction with diode setup: The address selection allows you to operate up to 3 receivers in the same room without interference. Each receiver shall have its own address setting.
Set-up ATTENTION: the receivers can only be operated by a transmitter allowing address setting. For the setting of the transmitter, we refer to the manuals of the kits in question.
Set-up If you want to mount the reception indication LED at a distance (cf. fig. 2.0), do not mount LD16 directly on the circuit board, but connect it to the board by means of a cable of the desired length. 1 2 3 1 2 3 1 2 3 FIG 2.0 Anode Cathode 3 SK11 2 1 USING SEVERAL RECEIVER INDICATIONS In case you want for each receiver a diagnostic LED, connect them parallel and each LED in series with a resistor (390Ω).
Testing the circuit 16. Testing the circuit Connect 2x6 to 2x12VAC or 8 to 14VDC / 150mA (see pag13). +V +V MAINS Before making a final connection we will test the circuit : VA GND 8 ... 14VDC / 150mA K8050 VB VA +V GND 1 VB 2 +V 1 3 2 4 5 6 7 12 6 ... 12v/150mA K8050 6 ... 12v/150mA Use a 2x6 to 2x12VAC power supply to feed the receiver or connect an 8 to 14VDC power supply between the points GND and VA or VB (Fig 2.0). FIG 2.
Testing the circuit Now test the inputs : Using your transmitter, choose each time a different output. Ex. Press 1 on your transmitter, normally LED LD1 should light. Repeat this for every output. All the LED’s should have lit up one by one. Test the outputs : You can check each output for correct operation, using a LED and resistor (390Ω) in series. Connect pin +V of SK2, see point A with the left side of the resistor (See fig 3.0) and connect the cathode side of the diode with the output 1.

Figure 4.0 shows how to connect eventual relays. Its advisable to use a separate power supply for the relays, rather than to branch off K8050 from the power supply of the receiver.
