Teaching the switching points in TEACH mode

The switching points for flow monitoring can be established in the TEACH mode è 4.2.3 Switching
outputs.
Before the teach-in, set the switching function to EDIT mode è 7.3 Configuring the sensor in EDIT
mode.
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.
