Generator will not start; controller shows E01 and immediately aborts cranking.

Safety first: Ensure the generator is in OFF mode, battery negative is disconnected if you will touch wiring, and the unit cannot start automatically.

• Check emergency stop button: Locate the red E‑STOP on the Aksa enclosure door or control panel. Turn or pull it to release. Reset the controller and attempt a start.
• Inspect external shutdown loop: Many Aksa standby sets have a remote shutdown input (fire alarm, remote E‑stop). Verify any remote E‑stop stations are reset and that the wiring is intact.
• Check controller inputs: On the Aksa controller I/O terminals, verify the emergency stop / remote stop input is closed using a multimeter. Repair any broken wires or loose terminal screws.
• Test the E‑stop switch: With power isolated, disconnect the E‑stop switch leads and check continuity while pressing/releasing. Replace the switch if it does not change state reliably.
• Clear code and retest: Reconnect wiring, reset the controller, and attempt a manual start. If E01 persists, the controller input may be faulty and professional service is recommended.
