Generator display shows E12 and engine stops abruptly without obvious mechanical noise

Safety first: Confirm that no real emergency exists before resetting any emergency stop devices.

• Step 1 – Check E‑stop button: Locate the red emergency stop button on the generator or remote panel. Twist or pull to reset it, depending on design.
• Step 2 – Inspect E‑stop wiring: Follow the two‑wire loop from the E‑stop button to the Kipor controller. Look for broken wires, loose terminals, or corrosion. Repair or replace as needed.
• Step 3 – Test switch: Use a multimeter to verify that the E‑stop switch opens and closes correctly when operated. Replace if intermittent or stuck.
• Step 4 – Clear fault: After correcting the issue, reset the controller and attempt a start. If E12 persists, the controller input may be faulty and require professional diagnosis.
