Alarm Code:

3. Emergency stop pressed or no pulse

Context where the error occurs:

This alarm can appear when an engine is running and no pulses are detected from the computer. The reason can be a broken pulse indicator. It also appears when the emergency stop is pressed down.

Solution:

Make sure the emergency stop is not applied. Test by pushing it down, release it by pulling it up

If the emergency stop is not applied, you must troubleshoot the engines.
