Controller displays E16, generator shuts down immediately after start

Safety first: Turn OFF the generator, open the main breaker, and verify no voltage is present at the output. Only qualified personnel should work on phase wiring.

• Step 1 – Verify controller settings: In the Multiquip controller menu, confirm that the frequency (50 or 60 Hz) and phase configuration match the generator nameplate and installation.
• Step 2 – Inspect phase sensing wiring: Locate the controller's phase sense terminals. Ensure all phase leads are connected to the correct terminals and are tight. Repair any damaged wires.
• Step 3 – Check engine speed: Start the generator with no load and measure frequency with a meter. If frequency is far from nominal, adjust engine speed per the service manual or have a technician calibrate the governor.
• Step 4 – Confirm phase rotation: Use a phase rotation meter at the generator output to verify correct rotation (e.g., ABC). If incorrect, a qualified electrician must swap two phases at the output lugs.
• Step 5 – Clear code and retest: After correcting wiring and settings, clear E16 and perform a test run under light load.
