Explanation of symbols and safety instructions 1 1 Explanation of symbols and safety instructions 1.1 Guideline to symbols Warnings Warnings are indicated in the text by a warning triangle and a gray background. In case of danger from electric shock, the exclamation point on the warning triangle is replaced with a lightning symbol. Signal words at the beginning of a warning are used to indicate the type and seriousness of the ensuing risk if measures for minimizing damage are not taken.
Explanation of symbols and safety instructions 1 WARNING: Only transformers with following specification are permitted: 6 V AC; 400 mA. The transformer is not part of the product! Please take care to use a reliable product which meets our requirements shown above. Do not mount the transformer internally! Buderus does not accept responsibility for systems which contravene the Installation instruction or addition documentation in scope of delivery.
2 2 Product description Product description 2.1 Correct use The Logamatic LON-Gateway may only be used to connect Buderus boilers with control panel from the Buderus Logamatic 4000 control series to superior control and/or building control systems via LON-BUS. 2.2 Disposal B Electronic components do not belong in household waste.

Incorporation of Logamatic 4000 in LON networks via Logamatic LON-Gateway 5 5 Incorporation of Logamatic 4000 in LON networks via Logamatic LON-Gateway 5.1 Structure of the hardware A main component of the products that communicate via LON data bus such as the Logamatic LONGateway is the neuron chip. Each neuron chip has a unique ID, the neuron ID making each device unique. For commissioning, operation, service or replacement, each device is identified via the unique neuron ID.
5 Incorporation of Logamatic 4000 in LON networks via Logamatic LON-Gateway 5.2.1 Commissioning LON networks The PC software saves the database structure in the respective project. In order to be able to use the functions created in the PC software, the assignment of the functions in the PC software to the device is required. This assignment takes place during "commissioning" via the neuron ID of the device.
