Switch on sensor (RUN mode)

• Switch on the operating voltage.
Ä Current measured value is displayed. The sensor is in the basic status
(RUN mode).
The basic static can be established using the following actions:
– Press the Edit button for 3 seconds
– Expiration of a monitoring time (timeout)

Switchover of measured value indicator

• Switchover to flow rate measurement: press A pushbutton.
• Switchover to volume measurement: press B pushbutton.

Displaying parameters (SHOW mode)

Requirement: The sensor is ready for operation (RUN mode).
Switching output OutA or volume pulse output
1. Press the A pushbutton twice.
Ä The first parameter set is displayed. [Fctn] flashes for OutA or [SP] flashes
for "Puls".
2. To display each of the following parameters, press the A pushbutton
(è Fig.10).
The averaged flow rate value [AVER] is displayed at the end.
Switching output OutB or analogue output Anlg
1. Press B pushbutton
Ä The first parameter set is displayed. [Fctn] flashes for OutB or [Out]
flashes for Anlg.
2. To display each of the following parameters, press the A pushbutton
(è Fig.10).

Enter the security code (EDIT mode)

Requirement: The sensor is ready for operation (RUN mode).
1. Press the Edit button.
Ä The EDIT mode is active. If the security code is activated, the parameter
entry option is blocked: [Lock] flashes.
2. Enter the set security code using the A or B pushbutton.
3. Press the Edit button briefly.
Ä [OutA] flashes. The parameter entry option is unblocked.
8.6 Configuring switching output (EDIT mode)
The process is the same for configuring the switching outputs for [OutA] and
[OutB.] In the following, the process is described using the switching output OutA.
Menu structure è 8.12 Menu structure (EDIT mode).
Requirement: The sensor is ready for operation (RUN mode).
1. Press the Edit button briefly.
Ä [Edit] appears. [OutA] flashes.
2. Press the Edit button briefly.
Ä [Fctn] flashes.
3. Select switching function _I¯ or _I¯I_ or d_I¯I_ with the A or B button.
4. Press the Edit button briefly.
Ä The set value is saved. The next adjustable parameter is shown.
5. Set the parameter with A or B pushbutton.
6. Repeat steps 4 and 5 until all parameters are set (switching functions
