Alarms, faults, and error codes from the Reactor 3 (E-30 and E-XP2) and the DSE7310 MKII controller, with plain-English explanations and actions.
When an alarm occurs, the equipment displays a code or message. This section helps you understand what it means and what to do. Always record the exact code and the conditions when it occurred — this information helps maintenance diagnose the root cause.
A WARNING alarm flashes and does not stop the equipment — but you should address it. A SHUTDOWN alarm is steady and stops the equipment to prevent damage. A ELECTRICAL TRIP alarm removes load but keeps the engine running. Always read the alarm type before taking action.
