Diagnosis / error messages
Definition – Alarms and Errors
Alarms
The actuator / electronic unit is in a critical state (e.g., high temperature), which currently does not affect the actuator, electronic
unit, process or persons.
The actuator functions are available. Previous alarms are stored in the ‘Saved Alarms’ area in the electronic unit. Use the graphic user
interface to read out saved alarms.
Errors
The actuator / electronic unit is in a critical state, e.g. control circuit monitoring, which is directly impairing the actuator, electronic
unit, process or persons.
The actuator is switched off and the actuator functions are no longer available. Previous error messages are stored in the ‘Saved
Errors’ area in the electronic unit. Use the graphic user interface to read out saved errors. Error messages cannot be reset until the
cause of the error has been eliminated.
