Building Energy Monitor

Non-invasive electrical monitoring for a permitted low-voltage demonstration system. Non-invasive electrical monitoring for a permitted low-voltage demonstration system.

Components

• Isolated low-voltage current/voltage measurement demo
• Regulated low-voltage bench supply
• Emergency stop or safe fallback input

Build steps

1. Inventory the board, actuators, sensors, and power rails listed for S09.
2. Build and inspect the low-voltage wiring against the supplied connection diagram before connecting actuators.
3. Flash the firmware, run the startup self-check, and record the printed board and firmware version.
4. Calibrate the sensors and limits, then run the acceptance tests at the lowest safe energy level.

Test and expected result

Compare measured current to a reference meter and verify safe isolation; no mains work without qualified supervision.

Safety and limits

No mains wiring by unqualified workers; use a certified low-voltage trainer.
