10. Operating modes
User operation depends on the system mode. The system modes are described in the following sections.
10.1 Local mode, external stop not activated
In this mode, the system is locally controlled, and the external stop via digital input is not activated.
The flow charts below show examples of how settings can be made.
Starting and stopping the system
Changing the setpoint while the system is running
Changing the setpoint while the system is in "OFF" mode
10.2 Local mode, external stop activated
In this mode, the system is locally controlled, and the external stop via digital input is activated.
External stop via digital input has higher priority than local control. This means that settings can be changed locally, but they will not be
effective until external stop has been deactivated. The flow charts below show examples of how settings can be made.
