Main State

A click on the "Main State" box of a system enables the change of the actual state.

The following information can be shown:

• Undefined (blue):

Undefined (blue):

Undefined (blue): The system is not running; no system information is available.

• Stopped (red):

Stopped (red):

Stopped (red): The system is stopped. The recording of data is still running.

• Online-Mode (green):

Online-Mode (green):

Online-Mode (green): The system is running by using the current measured pipeline data.

• Self Test-Mode (yellow):

Self Test-Mode (yellow):

Self Test-Mode (yellow): The system is running by using the recorded pipeline data.

• Tuning-Mode (blue):

Tuning-Mode (blue):

Tuning-Mode (blue): Maintenance activities are carried out on the monitoring station.
Therefore the leak detection is stopped at the moment.

• Application alarm (red):

Application alarm (red):

Application alarm (red): An internal error of the leak detection software has been detected.
System stopped working. A logged operator has to reset the alarm and to restart the system.
If the failure occurs several times please contact our support.

• Error (red):

Error (red):

Error (red): The application is not running correctly.

Pipeline State

Pipeline State
The following information can be shown:

• Undefined (blue):

Undefined (blue):

Undefined (blue): The system is not running; no information is available.

• Unknown (blue):

Unknown (blue):

Unknown (blue): The system is filling up the internal FIFOs. There is not enough information
available to estimate the pipeline conditions (possible after a restart of the system). The
information will be available soon.

• Shut-In (blue):

Shut-In (blue):

Shut-In (blue): The pipeline is running in shut-in conditions. Valves at the inlet and at the
outlet are closed.

• Multi Shut-in (blue):

Multi Shut-in (blue):

Multi Shut-in (blue): All valves are closed.

• Partial Shut-in (blue):

Partial Shut-in (blue):

Partial Shut-in (blue): At least one section is closed.

• Blocked Line (blue):

Blocked Line (blue):

Blocked Line (blue): Minimum one valve is closed, either at the inlet or at the outlet.

• Standstill (blue):

Standstill (blue):

Standstill (blue): No flow conditions along the line. The flow readings are below a predefined
value. Valves at the inlet and at the outlet are opened.

• Start-Up (blue):

Start-Up (blue):

Start-Up (blue): The pipeline start-up with pumping operations. The flow readings are above a
predefined value.

• Shutdown (blue):

Shutdown (blue):

Shutdown (blue): The pumping operations stopped.

• Nominal unknown (blue):

Nominal unknown (blue):

Nominal unknown (blue): The pipeline is running in pumping conditions at nominal flow level.
The system is filling the internal FIFOs. There is not enough information available to estimate
further exact pipeline conditions (possible after a restart of the system). Further pipeline
information about pipeline conditions will be available soon.

• Nominal high transient (blue):

Nominal high transient (blue):

Nominal high transient (blue): The pipeline is running in pumping conditions at nominal flow
level. High transient conditions detected by high variation of flow readings.

Watchdog

A click on the "Watchdog" box of one of the systems opens a dialogue windows which is showing
all available counters, monitored by the HMI.

The following information can be shown:

• OK:

OK:

OK: The watchdog counter of the system is updated within the timeout range.

• Alarm (red/flashing):

Alarm (red/flashing):

Alarm (red/flashing): The watchdog counter of the system is not updated and exceeds the
timeout range. The system might be not working correctly.
