1Manufacturing precision
If an electrical connection pattern is manually configured during system commissioning, then the system can be set up according to design requirements, but the process becomes complex and error-prone
Solution Approach 1:
The system automatically detects and validates the electrical connection pattern without manual intervention. The control device autonomously acquires measurement values from measuring devices, drives system components through test operating states, and validates the actual connection pattern against the provided pattern, eliminating manual configuration errors
Solution Approach 2:
The control device receives measurement values from measuring devices during automated tests and uses this feedback to determine whether the actual connection pattern matches the provided connection pattern. The system performs plausibility checks based on acquired measurement data and provides validation results to confirm correct installation
2Productivity
If manual checking of connection patterns is performed, then installation can proceed, but operational faults may occur due to incomplete or faulty patterns
Solution Approach 1:
The system performs automated validation of the electrical connection pattern during the commissioning phase before the system enters normal operation. By conducting plausibility checks and comparing actual connections against the provided pattern in advance, the system prevents operational faults from occurring during later use
Solution Approach 2:
The control device automatically executes validation tests by driving system components through different operating states and acquiring measurement values without requiring manual checking. This automated self-validation ensures both rapid commissioning and high operational reliability

AI summary
A method validates an electrical energy system in a building. The method includes providing a connection pattern of the electrical energy system. The connection pattern describes an arrangement of a plurality of components of the electrical energy system and the relative position and connections of the components. The method further includes setting the electrical energy system into a first operating state by driving at least one component. At least one measurement value is acquired in the first operating state. A plausibility check is carried out as a function of the at least one measurement value and the provided connection pattern. A signal is output as a function of the result of the plausibility check.
