Features & Specifications This dimmer is a plug-in module for our K8006 home modular light system suitable for incandescent lamps, and halogen lighting. This dimmer uses phase control technology. The main advantages of this technology are a reduced harmonic distortion on the mains and the fact that this dimmer can be used for electronic transformer, used in low voltage halogen lighting. Specifications: PLUG-IN’ module for use with our home modular light system K8006 only.
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 16. Installation & use Cut off the mains voltage of the K8006 (deactivate the main fuse of your switch box). Place the K8068 module into a free connector. Connect a load suitable for the specifications of this module ! You can now activate your K8006 Upon K8068 power-on, the LED (LD1) will flash briefly once (twice for 60Hz mains) during the internal diagnosis test. After this brief test, the module automatically switches to normal operation.
Installation & use LED indications in case of normal operation: Flashes once every 5 seconds when the module is in standby mode (lamp OFF). Flashes twice per second when the lighting is dimmed. Flashes 5x per second when the lighting is on at full brightness. Flashes once per second during a dimming cycle. LED indications in case of error: When an error is reported, the status LED is lit for a while and then flashes a number of times. The number of flashes indicates what problem has occurred.
