5.2 Zero point behaviour of the device display and outputs

Due to permissible device tolerances and temperature changes, the sensor can show a deviation from the zero point when no pressure is applied. To prevent this, the device is equipped with functions that keep the measured signal more stable at the process value 0.

Zero point behaviour of the device display and switching output:

Fig. 1: Device display and switching output

1: Process value
2: Sensor output signal with hysteresis (green)
3: Ideal measurement signal (red)
4: System pressure
5: Zero point stabilisation ➕ Data sheet

The first process value that is shown on the device display and can be evaluated via the switching output is determined by the zero point stabilisation.

The zero point stabilisation is specified in % of the span ➕ Data sheet.

Zero point behaviour of the analogue output and communication via IO-Link:

Fig. 2: Analogue output and communication via IO-Link

1: Process value
2: Sensor output signal (green)
3: Ideal measurement signal (red)
4: System pressure
5: Zero point stabilisation → Data sheet
6: 0.5 x zero point stabilisation → data sheet

The first process value that can be evaluated via the analogue output and the IO-Link communication is indicated by the half zero point stabilisation (6).

In the further range of the zero point stabilisation (5), the output signal of the sensor runs at a larger gradient angle.

The zero point stabilisation is specified in \% of the span ➞ Data sheet.

▶ Manually turn the display housing to the required position. Use a work glove if necessary.

Fig. 5: Rotate display: 1: Display on delivery; 2: Display rotated by 90°.

6.5 Ventilation diaphragm

6.5.1 Function of ventilation diaphragm

The ventilation diaphragm enables the relative pressure measurement since barometric and temperature-dependent pressure fluctuations between the measuring cell and the environment are compensated for.

The ventilation diaphragm is protected against damage by a screwed filter cover with circumferential ports.

For a correct functioning of the diaphragm please take the following into account:

▶ Remove soiling or cleaning agents on the filter cover immediately using plenty of lime-deficient splash water.

ATTENTION

Contact of the diaphragm with liquid during a cooling phase

▷ Negative pressure in the device.
▷ Slight distortion of the measured value.
▷ Additional strain on the diaphragm.
▶ Make sure that there is no liquid in the filter cover while the sensor is in a cooling phase.

6.5.2 Replace filter cover

The ventilation diaphragm is protected by a filter cover applied at the factory.

The filter cover can be replaced with accessories 2...5 (→ figure).

Information about available accessories at www.ifm.com

Fig. 6: Replacing the filter cover of the ventilation diaphragm

1: Filter cover (as supplied)
2: Filter cover with integrated ventilation diaphragm
3: Closed filter cover
4: Filter cover with integrated ventilation diaphragm and tube fitting with vent tube that ends in a protected and dry area.

- vent tube – or –
- plug-in element with integrated ventilation diaphragm – or –
- plug-in element with integrated ventilation diaphragm and vent tube

When using the closed filter cover (3), there is no pressure compensation of the measuring cell any more. Potential measurement deviations caused by:

- fluctuations of the atmospheric pressure.

- pressure fluctuations inside the device in case of temperature fluctuations ( Δ 10 K ≤ 30 mbar ).

How to proceed:

▶ Avoid soiling and moisture during the replacement.

▶ Clean the thread carefully and without residues.
▶ Do not damage the adhesive area of the sensor.
▶ Observe the orientation of the filter cover.

6.5.3 Orientation filter cover

▶ Install the device so that the filter cover is vertical and the condensate can drain off due to gravity.

10 Commissioning

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.

During the power-on delay time, the outputs are in the following status according to the set parameters:

Switching output:

• Active (“high” with normally open function; “low” with normally closed function)

Analogue output:

• 0 mA with current output (I or I_neg )

When an IO-Link master is connected, the device automatically goes from SIO mode (standard input-output) into IO-Link mode if the port of the master is set to IO-Link mode.

11 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.

11.1 Parameter setting via the unit keys

The term “device keys” refers to the touch buttons Enter, ▲ and ▼.

The touch button Enter is indicated by the ● icon below.

The sensor fields of these optical keys are operated simply by touching the viewing glass. The touch button must be completely covered to be activated. Slow covering (e.g. liquid flows over the display) does not activate the touch button.

11.3 Output configuration

11.3.1 Digital switching signal

The device provides digital switching signals via switching signal channels (SSC = Switching Signal Channel).

The device has two digital switching signal channels SSC1.1 and SSC1.2 which can be used to output the process value.

Explanation of the numbering of the switching signal channels SSCx.y: x = process value; y = switching signal channel

The switching channels can be analysed via the IO-Link interface and the hardware output.

The switching signal channel SSC1.1 is permanently assigned to the physical hardware output OUT1.

The switching signal channel SSC1.2 can only be read via the IO-Link interface.

The parameters for each switching signal channel can be set individually.

During parameter setting, the switch points, mode and logic of the switching signal channels are set.

Mode

You can choose between the following modes according to the IO-Link smart sensor profile – Function Class “Quantity Detection”:

• Deactivated
• Single Point Mode
• Two Point Mode
• Window Mode

The switching signal channel changes to the active state depending on the process data value (PDV).

The active state is above the switch point in Single Point Mode and Two Point Mode and within the window section in Window Mode.

Logic

By setting the logic High active or Low active, you can specify which value the switching signal channel has in the active state:

• High active: The switching signal channel is "high" in the active state (= ON = normally open = 1)
• Low active: The switching signal channel is "low" in the active state (= OFF = normally closed = 0)

The following figures show the status of the switching signal channels depending on the mode, logic and process data value (PDV).

Deactivated

If the Deactivated mode is set for a switching signal channel, the switching signal channel will permanently have the following value regardless of the process value:

• For logic High active: permanently "low".
• For logic Low active: permanently "high".

Fig. 12: Deactivated / High active

Fig. 13: Deactivated / Low active

Single-point mode

Only one switch point SP1 is manually set or taught.

The reset point SP1-H results from the switch point and the set hysteresis.

When teaching, the switch point is set below the taught process value TP1 by the hysteresis.

SP1: Switch point

TP1: Teach point

TP1-H: Switch point during teach (= SP1)

SP1-H Reset point

Two-point mode

A switch point SP1 and a switch point SP2 are manually set or taught.

When setting the parameters via IO-Link, the position of the switch points can be freely selected: SP1 can be below or above SP2. The lower switch point is the reset point. In the example shown, SP1 is the set-point and SP2 is the reset point.

When setting the parameters via the device keys, SP1 must be greater than SP2. If the order of the switch points is subsequently reversed via IO-Link, then SP1 must be smaller than SP2 in the future when setting parameters via the device keys.

When teaching, the switch point is set directly to the respective taught process value TPx.

The hysteresis will be ignored in Two Point Mode.

Fig. 17: Two Point Mode / Low active

SP1: Switch point 1

SP2: Switch point 2

TP1: Teach point 1 (= SP1)

TP2: Teach point 2 (= SP2)

Window mode

Two switch points SP1 and SP2 are manually set or taught.

The two switch points define a window area.

When setting the parameters via IO-Link, the position of the switch points can be freely selected: SP1 can be below or above SP2. The lower switch point is the lower limit value, the higher switch point is the upper limit value of the window area.

When setting the parameters via the device keys, SP1 must be greater than SP2. If the order of the switch points is subsequently reversed via IO-Link, then SP1 must be smaller than SP2 in the future when setting parameters via the device keys.

When teaching, the switch point is set directly to the respective taught process value TPx.

When the process data value enters the window area, the status of the switching signal channel changes when the switch points are exceeded/not reached.

When the process data value leaves the window area, the status of the switching signal channel changes when the switch point plus/minus the hysteresis is exceeded/not reached.

For each colour range, you can set a start value with x. StA and an end value with x. End.

The limits of the colour ranges can be freely selected within the measuring range and are independent of the set switch points.

Minimum distance between x. StA and x. End = 5 % of the measuring span (e.g: For a sensor with -1...10 bar measuring range: 0.55 bar

For each colour range, the colour of the segments in the LED ring can be set using x. CoL:

• rEd = red
• GrEn = green
• YELL = yellow
• bLuE = blue
  • cYAn = cyan
