A start failure alarm on an Atlas Copco QAS 500 could be caused by:

- Bad connection: Check wiring.
- Low battery voltage: Battery may be drained; charge the battery or install a charger.
- Charging alternator broken: Measure battery voltage during operation; replace alternator if voltage is not correct.
- Battery broken: Replace the battery.
- Low oil pressure: Fill oil to the correct level and check for leaks.
- Faulty oil pressure sensor: Replace sensor.
- Oil sump broken: Check or contact Atlas Copco.
- Emergency stop activated: Reset it manually after resolving the issue.

These conditions can block engine start and trigger alarms in the diagnostics menu.
