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.
Assembly hints ⇒ 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.

Noise suppression 15. Noise suppression of the relay contacts “OPTIONAL !” : At the standard module K6714 as well K6714-16 have you the opportunity to noise-suppress every relay contact.
Important 16. IMPORTANT : If you want an electronic controller to be able to switch higher currents and at the same time you need an insulation between the controller and the controlled items, then a relay module is an indispensable help. The module is very well suited to be connected to our kits K6711 (15 channel IR receiver) and one or two times K8023. For those two kits power can be taken direct from the relay module. The module can also be used together with the open collector interface module K8000.
Test and connections 17. TEST AND CONNECTIONS : Connect the phase to “0” and the Neutral to “125” or “220”, depending on the mains voltage. Normally the POWER ON LED should be lit now. In case no manual operation has been provided, you can test the relay by connecting the inputs (terminals 1 trough 16) to earth (GND) one after another. Connections possibility's : 1. Connect the board to the 15 channel receiver K6711 (see Fig. 1.0) FIG 1.0 10 H67146(16)IP'1_rev1.
Test and connections 2.

Tips at malfunctions 18. Remedies in the case of malfunction caused by the relays If the relays are used to switch alternating voltage, it may be necessary to suppress them. 1. Suppressing resistive loads (Lamp, resistor,…) : Fig. 3.1 2. Suppressing inductive loads (Transformer, motor,…) : Fig. 3.2 3. When above solutions fail : In this last case an independently feeded DC-relay is used, wich is installed as close to the load as possible.
