Teaching the switching points in TEACH mode
The switching points for flow monitoring can be established in the TEACH mode
Before the teach-in, set the switching function to EDIT mode
7.3 Configuring the sensor in EDIT
The procedure for teaching the OutA or OutB switching signal is the same in principle:
–
OutA: press the [A] key.
–
OutB: press the [B] key.
In the following, the procedure for the switching signal OutA is described.
Requirement: the sensor is ready for operation and is in RUN mode.
1. Generate the flow rate for TP1.
2. Press the [A] key and the [Edit] key.
Ä
With security code activated: [Lock] flashes.
3. Set the security code with the [A] or [B] key.
4. Press the [Edit] key.
Ä
‘t-IN’ flashes.
Ä
The measured value will then be applied as teach point (TP1).
5. Generate the flow rate for TP2.
6. Press the [A] key and the [Edit] key.
Ä
The measured value will then be applied as teach point (TP2).
Ä
The ‘SP’ switching point of the ‘SP.Lo’ and ‘SP.Hi’ switching points become valid.
Ä
The RUN mode is displayed.
7.5
Measuring volume manually in RECORDER mode
Requirement: the sensor is ready for operation and is in RUN mode.
1. Press the [A] and [B] keys simultaneously.
Ä
The current status of the measurement is displayed.
2. To start or stop the measurement, press the [A] key.
3. To reset the measurement, press the [B] key.
4. To exit RECORDER mode, press the [A] and [B] key simultaneously.
Ä
The RUN mode is displayed.
If the RECORDER mode is exited during a volume measurement, the measurement will continue in the
background.
If the operating voltage is switched off, the measurement is aborted without saving the value.
