The status of the integrated flow controller can be determined from both, status of integrated pump and
status of integrated flowmeter and is summarized in Table 16 with the most important state combinations,
state description and possible corrective actions.

Speed Control Mode. Flow controller runs at a
frozen speed, because the flow sensor has
measurement errors.
The speed is by default 0 rpm and can be
changed.
Check flow sensor cabling and connections.
Remove bubbles in flow sensor.
Zero Adjust of flow converter if medium
characteristics have changed.

Speed Control Mode. Flow controller runs at a
frozen speed, because the flow sensor has a
zero adjustment errors.
The reference speed is the last determined
value before the error appeared in the Flow
Control Mode.
Stop flow controller.
Make sure there is no flow through the sensor.
Activate Zero Adjust to start a new Zero Adjust.
Active
