Multi-Channel Dimmer Self-Commissioning via Parallel Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The commissioning of multi-channel dimmers is time-consuming due to the need for manual disabling of individual functions during the setup process, which affects the efficiency, reliability, and safety of the lighting control system.
Innovation Solution
A method that automates the decommissioning of functions for individual dimmer channels by using a test procedure where the control circuit emits control signals to determine parallel connections and automatically deactivates unnecessary local controls and extension inputs, allowing for streamlined commissioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual decommissioning of functions is performed during commissioning, then reliability and safety are ensured, but commissioning time increases
Solution Approach 1:
The multi-channel dimmer performs self-commissioning by automatically detecting parallel connections between dimmer channels and decommissioning functions without manual intervention. The control circuit autonomously identifies which channels are connected in parallel and disables appropriate local control buttons and extension inputs, eliminating the need for manual decommissioning while ensuring reliable system configuration.
2Ease of operation
If all dimmer channel functions are enabled during commissioning, then ease of operation is maintained, but safety and reliability are compromised due to potential conflicts
Solution Approach 1:
The control circuit performs preliminary detection of parallel connections between dimmer channels before enabling full operation. By identifying connected channels in advance and pre-decommissioning conflicting functions, the system ensures that only appropriate functions are active, preventing operational conflicts while maintaining ease of use during commissioning.
3Reliability
If manual decommissioning is required, then safety is maintained, but productivity decreases due to time-consuming commissioning
Solution Approach 1:
The system performs self-commissioning by automatically detecting parallel connections and decommissioning functions without manual intervention. The control circuit autonomously identifies connected channels and disables appropriate local control buttons and extension inputs, eliminating time-consuming manual decommissioning while ensuring safe and reliable system configuration.
4Reliability
If multiple functions are manually disabled, then reliability is improved, but device complexity increases due to manual configuration requirements
Solution Approach 1:
The control circuit automatically detects parallel connections between dimmer channels and autonomously decommissions appropriate functions without manual configuration. This self-service approach simplifies the commissioning process while maintaining reliable operation, as the system independently determines which functions to disable based on detected channel connections.

AI summary
The method involves executing and evaluating a test procedure by a control circuit (52) after occurrence of connection of a load (14) to respective dimmer channels (6, 16, 23, 35, 43). One of the channels is successively and separately controlled during a given time interval, by the control circuit. A voltage signal available at an outlet (13) is detected by control electronics of the channels. The dimmer channels switched parallel to composite dimmer groups (5, 34) are determined based on the detected voltage signal, by the control circuit.
