9 Set-up

After power on and expiry of the power-on delay time, the unit is in the normal operating mode. It carries out its measurement and evaluation functions and generates output signals according to the set parameters.

For analogue output 2 (OUT2), the output signal is 20 mA during the power-on delay time.

For the first 2 seconds, analogue output 1 (OUT1) is passive and available for IO-Link communication. During the remaining power-on delay time, the output signal is at 20 mA.

10 Parameter setting

Parameter setting can be carried out via the IO-Link interface or via the operating elements on the unit.

Parameters can be set before installation or during operation.

If you change parameters during operation, this will influence the function of the plant.

▶ Ensure that there will be no malfunctions in your plant.

During parameter setting the unit remains in the operating mode. It continues to monitor with the existing parameter until the parameter setting has been completed.

Depending on the parameter setting, the parameters available in the menu may change.

10.1 Parameter setting via the unit keys

CAUTION

If the medium temperature is above 50\ °C ( 122\ °F ), parts of the housing can increase in temperature to over 65\ °C ( 149\ °F ).

▷ Risk of burns
▶ Do not touch the device with your hands.
▶ Use another object (e.g. a ballpoint pen) to carry out settings on the unit.

Notes on parameter setting → Manual of the parameter setting software.

10.3 Output configuration

10.3.1 Standard unit of measurement

A unit of measurement can be selected with which the process value is shown in the display by default. All further parameter settings are based on this unit.

Selectable values:

Flow: l/min; m³/h ; for SVx6xx device types: gpm; gph.

10.3.1.1 Parameter setting via the device keys: Standard unit of measurement

▶ Call up the menu [EF] > [CFG].
▶ Select [uni] and set the unit of measurement.

10.3.1.2 Parameter setting via IO-Link: Standard unit of measurement

▶ Call up [Parameters] > [Display Setting].
▶ Select [uni] and set the unit of measurement.

10.3.2 Analogue signal

The unit provides an analogue signal of 4...20 mA proportional to the process value.

The measuring range is scalable:

• [ASP] determines at which measured value the output signal is 4 mA.
• [AEP] determines at which measured value the output signal is 20 mA.

Minimum distance between ASP and AEP = 20 % of the final value of the measuring range.

For measured values outside the display range or in case of an error, messages are displayed (cr. UL, UL, OL, cr. OL, Err).

The analogue signal in case of a fault can be set via the parameter [FOU].

10.3.2.1 Parameter setting via unit keys: Analogue signal

√ Standard unit of measurement is selected: [EF] > [CFG] > [Uni].
▶ Call up the [main menu].
▶ Set the parameters for the temperature measurement: [ASP1] and [AEP1].
▶ Set the parameters for the flow measurement: [ASP2] and [AEP2].

10.3.2.2 Parameter setting via IO-Link: Analogue signal

√ Standard unit of measurement is selected: [Parameter] > [Setting of the sensor display] > [uni].
▶ Call up the menu [Parameters] > [Analogue output 1] and set the parameters for the temperature measurement: [ASP1] and [AEP1].

▶ Call up the menu [Parameters] > [Analogue output 2] and set the parameters for the flow measurement: [ASP2] and [AEP2].

10.3.3 Damping

The set damping constant stabilises the output signals. Abrupt changes in the physical process values are smoothed out.

This concerns the outputs and the display.

The damping constant is added to the response time of the sensor ( → Technical data).

The UL and OL signals are defined under consideration of the damping time.

i

Measured value damping only has an effect on the measured variable flow.

10.3.3.1 Parameter setting via device buttons: Damping

▶ Call up the menu [EF] > [CFG].
▶ Select [dAP] and set the damping time in seconds (T-value 63 %).

10.3.3.2 Parameter setting via IO-Link: Damping

▶ Call up [Parameters] > [Damping].
▶ Select [dAP] and set the damping time in seconds (τ-value 63 %).

10.3.4 Error behaviour of the outputs

The response of the OUTx output in case of a fault can be set via the parameter [FOUx]. Depending on the selected output function, the following signals are provided in case of a fault:

• On: The analogue signal goes to 22 mA.
• OFF: The analogue signal goes to 3.5 mA.
• OU: The analogue signal still corresponds to the measured value.

10.3.4.1 Parameter setting via unit keys: Error behaviour of the outputs

▶ Call up the menu [EF] > [CFG].
▶ Select [FOUx] and set the error behaviour for OUTx: [On], [OFF], [OU].

10.3.4.2 Parameter setting via IO-Link: Error behaviour of the outputs

▶ Call up [Parameters] > [Error Configuration Output x].
▶ Select [FOUx] and set the error behaviour for OUTx: [On], [OFF], [OU].

10.4 Memory

The unit stores the maximum and minimum measured process values.

The current value can be read from the unit's display or via the IO-Link interface.

Selectable values:

• [Lo. F]: Minimum value memory for volumetric flow
• [Hi. F]: Maximum value memory for volumetric flow
• [Lo. T]: Minimum value memory for temperature

• [Hi. T]: Maximum value memory for temperature

It makes sense to delete the memories as soon as the unit operates under normal operating conditions for the first time.

▶ Go to the [EF] > [MEM] menu.
▶ Read the value for the minimum and maximum stored process value.

• d2: medium
• d3: slow

10.5.3 Display rotation

Use the parameter [diS. R] to rotate the text in the display clockwise for better readability.

Selectable values:

• 0° (not rotated)
  • 90°
  • 180°
  • 270°

10.5.4 Display brightness

The display brightness can be set via the parameter [diS. B].

Selectable values:

• 100%

- OFF: energy-saving mode. The display is switched off in the operating mode. Display activation by pressing any key. After 30 s of inactivity, the display is switched off again.

In case of warnings or error messages, the display will come back on even with the setting [OFF].

10.5.5 Display colour setting

The font colour in the display can be set via the parameter [coL.x].

• [coL. F]: font colour for flow
• [coL. T]: font colour for temperature

Permanent font colour

The display font colour for flow and temperature can be set permanently:

Setting for [coLx]	Font colour
[rEd]	Red
[GrEn]	Green

Colour change

Alternatively, a colour change can be configured for the displayed flow and temperature depending on the current process value:

Setting for [coL.x]	Font colour
[r-cF]	Red = process value inside window Green = process value outside window
[G-cF]	Green = process value inside window Red = process value outside window

If “Colour change” is selected, the limit values of the window section must be set via the parameters [cFL.x] and [cFH.x]. The limits can be freely selected within the measuring range and are independent of the output function.

Fig. 5: Colour change in the window section. Example: [coL.x] = [G-cF]

cFL. F: Lower limit for flow

cFL. T: Lower limit for temperature

cFH. F: Upper limit for flow

cFH. T: Upper limit for temperature
