Features & Specifications This dimmer is a plug-in module for our K8006 home lighting system. Just like its predecessor K8007, it was designed for the dimming of conventional incandescent lamps and halogen lighting. Not only is this kit easy to operate with just one push button, it is also equipped with numerous safety features. With low-voltage halogen lighting the transformation from mains voltage to 12V lamp voltage is to be achieved by means of a wire-wound transformer.
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.

Installation & use 20. Installation & use Cut off the mains voltage of the K8006 (deactivate the main fuse of your switch box). Mount the jumpers in locations JP1,2, 3. (see fig. 1.0) to select the settings (see page 12). LD1 (Red) LD2 (Yellow) JP3 JP2 1 2 3 JP1 : Memory function JP2 : Safe min. Luminous itensity. JP3 : Deactivation timer. JP1 Place the K8037 module into a free connector.
Installation & use You can now activate your K8006 When you start up your K8037, LD1 & LD2 will flash together for a couple of seconds until the self-test is completed. The indication LEDs display any irregularity the CPU may discover (read "LED indication in case of error" below). Following the self-test, LD2 will flash once when the net frequency is 50Hz or twice for 60Hz. The module is now operational.
Installation & use LED indications in case of error: When the CPU detects an error, LD1 (red) can provide an indication as to the nature of the problem. LD2 (yellow) will then remain lit continuously, whereas LD1 (red) will repeatedly flash a number of times: We advise you to briefly interrupt the supply voltage and evaluate the situation. It is possible to restart the module without interrupting the voltage: hold the operation button for at least 10 seconds (until both LEDs are extinguished).
Jumper selection 21. Jumper selection The settings of the dimmer module are determined by placing a shunt (=jumper) over pins 1-2 or 2-3 of JP1, 2 and 3 (see figure 1.0). The operation of the device becomes unstable if the jumpers are not mounted. JP1 – Memory function: The last used luminous intensity is stored in the memory if this function is activated. 1-2: Memory function is deactivated. or 2-3: Memory function is activated. JP2 – Safe min.
Jumper selection JP3 – Deactivation timer: Lamps are automatically deactivated after ± 12 hours of continuous use when this function is activated: 1-2: Deactivation timer is deactivated. or 2-3: Deactivation timer is activated. The “TP” connection on the print is only used by the people in our technical department.
