• Protect housing against impact.
• For devices with gauge pressure sensor, the following applies:
NOTICE
If a heated device is cooled in the course of a cleaning process (by cold water, for
example), a vacuum develops for a short time causing moisture to penetrate the
sensor via the pressure compensation element (1).

8.1 Process data
The measuring device has a current output and a switch output. The status of the switch
output is transmitted in the form of process data via IO-Link.
• In the SIO mode, switch output 1 is switched at pin 4 of the M12 plug. In the IO-Link
communication mode, this pin is reserved exclusively for communication.
• The current output at pin 2 of the M12 plug is always active or can be optionally
deactivated via IO-Link.
• The device's process data are transmitted cyclically in 32-bit chunks.

Bit 31 is reserved. Bit 30 provides the status of the switch output.
Here, 1 or DC 24 V corresponds to the logical "closed" state on the switch output. The
remaining 30 bits contain the analog raw measured value of the device. This value has yet
to be scaled by the target system to the nominal operating range of the existing measuring
device.

9.3 Configuring pressure measurement
9.3.1 Calibration without reference pressure (dry calibration =
calibration without medium)
Example:
In this example, a device with a 400 mbar (6 psi) sensor is configured for the measuring
range 0 to 300 mbar (0 to 4.4 psi).
The following values should be assigned:
• 0 mbar = 4 mA value
• 300 mbar (4.4 psi) = 20 mA value
Prerequisite:
This is a theoretical calibration, i.e. the pressure values for the lower and upper range are
known. It is not necessary to apply pressure.
Due to the orientation of the device, there may be pressure shifts in the measured
value, i.e. the measured value is not zero in a pressureless condition. For information
on how to perform position adjustment, see the "Performing position adjustment"
section → 27.
For a description of the parameters mentioned and possible error messages, see the
"Description of device parameters" section → 44 and → 37.
Performing the configuration
1.Select a pressure unit, here "bar" for example, via the Unit changeover (UNI)
parameter.
2.Select Value for 4 mA (STL) parameter. Enter the value (0 bar (0 psi)) and confirm.
This pressure value is assigned to the lower current value (4 mA).
3.Select Value for 20 mA (STU) parameter. Enter the value (300 mbar (4.4 psi)) and
confirm.
This pressure value is assigned to the upper current value (20 mA).
The measuring range is configured for 0 to 300 mbar (0 to 4.4 psi).

The following values should be assigned:
• 0 mbar = 4 mA value
• 300 mbar (4.4 psi) = 20 mA value
Prerequisite:
The pressure values 0 mbar and 300 mbar (4.4 psi) can be specified. The device is already
mounted, for example.
Due to the orientation of the device, there may be pressure shifts in the measured
value, i.e. the measured value is not zero in a pressureless condition. For information
on how to perform position adjustment, see the "Performing position adjustment"
section → 27.
For a description of the parameters mentioned and possible error messages, see the
"Description of device parameters" section → 44 and → 37.
Performing the configuration
1.Select a pressure unit, here "bar" for example, via the Unit changeover (UNI)
parameter.
2.The pressure for the LRV (4 mA value) is present at the device, here 0 bar (0 psi) for
example. Select Pressure applied for 4mA (GTL) parameter. The selection is
confirmed by pressing "Get Lower Limit".
The pressure value present is assigned to the lower current value (4 mA).
3.The pressure for the URV (20 mA value) is present at the device, here
300 mbar (4.4 psi) for example. Select Pressure applied for 20mA (GTU)

9.4 Performing position adjustment
Zero point configuration (ZRO)
NavigationParameter → Application → Sensor → Zero point configuration (ZRO)
Description(Typically absolute pressure sensor)
A pressure shift resulting from the orientation of the device can be corrected by the
position adjustment.
The pressure difference between zero (set point) and the measured pressure must be
known.
PrerequisiteAn offset is possible (parallel shifting of the sensor characteristic) to correct the
orientation and any zero point drift. The set value of the parameter is subtracted from the
"raw measured value". The requirement to be able to perform a zero point shift without
changing the span is met with the offset function.
Maximum offset value = ± 20 % of the sensor nominal range.
If an offset value is entered that shifts the span beyond the physical limits of the sensor,
the value is admitted but a warning message is generated and displayed via IO-Link. The
warning message only disappears when the span is within the sensor limits, taking the
offset value currently configured into consideration.
The sensor can
• be operated in a physically unfavorable range, i.e. outside its specifications, or
• be operated by making appropriate corrections to the offset or span.
Raw measured value – (manual offset) = display value (measured value)
Example• Measured value = 0.002 bar (0.029 psi)
• Set the manual offset to 0.002.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.
NoteSetting in increments of 0.001. As the value is entered numerically, the increment
depends on the measuring range

Raw measured value – (manual offset) = display value (measured value)
Example 1• Measured value = 0.002 bar (0.029 psi)
• Use the Zero point adoption (GTZ) parameter to correct the measured value with the
value, e.g. 0.002 bar (0.029 psi). This means that you are assigning the value
0 bar (0 psi) to the pressure present.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.
• Where applicable, check and correct switch points and span settings.
Example 2Sensor measuring range: –0.4 to +0.4 bar (–6 to +6 psi) (SP1 = 0.4 bar (6 psi); STU =
0.4 bar (6 psi))
• Measured value = 0.08 bar (1.2 psi)
• Use the Zero point adoption (GTZ) parameter to correct the measured value with the
value, e.g. 0.08 bar (1.2 psi). This means that you are assigning the value 0 mbar (0 psi)
to the pressure present.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.
• Warnings C431 or C432 appear because the value 0 bar (0 psi) was assigned to the real
value of 0.08 bar (1.2 psi) present and the sensor measuring range was thus exceeded
by ± 20%.
SP1 and STU values must be readjusted downwards by 0.08 bar (1.2 psi).

9.5 Configuring process monitoring
To monitor the process, it is possible to specify a pressure range which is monitored by the
limit switch. Both monitoring versions are described below. The monitoring function
allows the user to define optimum ranges for the process (with high yields etc.) and deploy
limit switches to monitor the ranges.
9.5.1 Digital process monitoring (switch output)
It is possible to select defined switch points and switchback points which act as NO or NC
contacts depending on whether a window function or hysteresis function is configured.

If the device is restarted within the given hysteresis, the switch output is open (0 V present
at the output).
9.5.2 Analog process monitoring (4 to 20 mA output)
• The 3.8 to 20.5 mA signal range is controlled according to NAMUR NE 43.
• The alarm current and current simulation are exceptions:
• If the defined limit is exceeded, the device continues measuring linearly. The output
current increases linearly up to 20.5 mA and holds the value until the measured value
drops below 20.5 mA again or the device detects an error → 37.
• If the defined limit is undershot, the device continues measuring linearly. The output
current decreases linearly to 3.8 mA and holds the value until the measured value rises
above 3.8 mA again or the device detects an error → 37.

NavigationParameter → Application → Switch output 1 → Switch point value.../Switchback point

PrerequisiteThe following functions are available only if a hysteresis function has been configured for
the switch output (output 1 (Ou1)).
Description of behavior of
SP1/RP1
The hysteresis is implemented using the SP1 and RP1 parameters. Since the parameter
settings depend on one another, the parameters are described all together.
The switch point "SP1" and switchback point "RP1" can be defined with these functions (e.g.
for pump control). When the set switch point "SP1" is reached (with increasing pressure),
an electrical signal change takes place at the switch output. When the set switchback point
"RP1" is reached (with decreasing pressure), an electrical signal change takes place at the
switch output. The difference between the value of switch point "SP1" and the value of
switchback point "RP1" is known as the hysteresis. The configured value for the switch
point "SP1" must be greater than the switchback point "RP1"! A diagnostic message is
displayed if a switch point "SP1" is entered that is ≤ the switchback point "RP1". While it is
possible to make this entry, it does not take effect in the device. The entry must be
corrected!

PrerequisiteThe following functions are available only if a window function has been configured for
the switch output (output 1 (Ou1)).
Description of behavior of
FH1/FL1
The window function is implemented using the FH1 and FL1 parameters. Since the
parameter settings depend on one another, the parameters are described all together.
The upper value of the pressure window "FH1" and the lower value of the pressure window
"FL1" can be defined with these functions (e.g., for monitoring a certain pressure range).
When the lower value of the pressure window "FL1" is reached (with increasing or
decreasing pressure), an electrical signal change takes place at the switch output. When
the upper value of the pressure window "FH1" is reached (with increasing or decreasing
pressure), an electrical signal change takes place at the switch output. The difference
between the upper value of the pressure window "FH1" and the lower value of the pressure
window "FL1" is known as the pressure window. The upper value of the pressure window
"FH1" must be greater than the lower value of the pressure window "FL1"! A diagnostic
message is displayed if the upper value entered for the pressure window "FH1" is less than
the lower value of the pressure window "FL1". While it is possible to make this entry, it
does not take effect in the device. The entry must be corrected!

NoteThe switching delay time/switchback delay time function is implemented using the dS1

DescriptionTo prevent switch-on and switch-off if values are around the switch point "SP1" or the
switchback point "RP1", a delay in a range of 0 – 50 seconds, to two decimal places, can be
set for the individual points.
If the measured value leaves the switching range during the delay time, the delay time
starts again.

10.3 Behavior of the device in the event of a fault
The device displays warnings and faults via IO-Link. All the device warnings and faults are
for information purposes only and do not have a safety function. The errors diagnosed by
the device are displayed via IO-Link in accordance with NE107. Depending on the
diagnostic message, the device behaves as per a warning or fault condition. A distinction
must be made between the following types of error here:
• Warning:
• The device continues measuring if this type of error occurs. The output signal is not
affected (exception: simulation is active).
• The switch output remains in the state defined by the switch points.
• Fault:
• The device does not continue measuring if this type of error occurs. The output signal
adopts its fault state (value in the event of an error - see the following section).
• The fault state is displayed via IO-Link.
• The switch output changes to the "open" state.
• For the analog output option, an error is signaled with the configured alarm current
behavior.
10.4 Behavior of current output in the event of a fault
The behavior of the current output in the event of a fault is regulated in accordance with
NAMUR NE43.
The behavior of the current output in the event of faults is defined in the following
parameters:
• Alarm current FCU "MIN": Lower alarm current (≤3.6 mA) (optional, see the following
table)
• Alarm current FCU "MAX" (factory setting): Upper alarm current (≥21 mA)
• The selected alarm current is used for all errors.
• Errors and warning messages are displayed via IO-Link.
• It is not possible to acknowledge errors and warnings. The relevant message
disappears if the event is no longer pending.
• The failsafe mode can be changed directly when a device is running (see the
following table).

DescriptionThe simulation affects the process data only. It does not affect the physical switch output.
If a simulation is active, a warning to this effect is displayed so that it is obvious to the user
that the device is in the simulation mode. A warning is communicated via IO-Link (C485 simulation active). The simulation must be ended actively via the menu. If the device is
disconnected from the power supply during the simulation and power is then resupplied,
the simulation mode is not resumed, and instead the device continues operation in the

PrerequisiteAn offset is possible (parallel shifting of the sensor characteristic) to correct the
orientation and any zero point drift. The set value of the parameter is subtracted from the
"raw measured value". The requirement to be able to perform a zero point shift without
changing the span is met with the offset function.
Maximum offset value = ± 20 % of the sensor nominal range.
If an offset value is entered that shifts the span beyond the physical limits of the sensor,
the value is admitted but a warning message is generated and displayed via IO-Link. The
warning message only disappears when the span is within the sensor limits, taking the
offset value currently configured into consideration.
The sensor can
• be operated in a physically unfavorable range, i.e. outside its specifications, or
• be operated by making appropriate corrections to the offset or span.
Raw measured value – (manual offset) = display value (measured value)
Example• Measured value = 0.002 bar (0.029 psi)
• Set the manual offset to 0.002.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.

Example 1• Measured value = 0.002 bar (0.029 psi)
• Use the Zero point adoption (GTZ) parameter to correct the measured value with the
value, e.g. 0.002 bar (0.029 psi). This means that you are assigning the value
0 bar (0 psi) to the pressure present.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.
• Where applicable, check and correct switch points and span settings.
Example 2Sensor measuring range: –0.4 to +0.4 bar (–6 to +6 psi) (SP1 = 0.4 bar (6 psi); STU =
0.4 bar (6 psi))
• Measured value = 0.08 bar (1.2 psi)
• Use the Zero point adoption (GTZ) parameter to correct the measured value with the
value, e.g. 0.08 bar (1.2 psi). This means that you are assigning the value 0 mbar (0 psi)
to the pressure present.
• Display value (measured value) after position adjustment = 0 bar (0 psi)
• The current value is also corrected.
• Warnings C431 or C432 appear because the value 0 bar (0 psi) was assigned to the real
value of 0.08 bar (1.2 psi) present and the sensor measuring range was thus exceeded
by ± 20%.
SP1 and STU values must be readjusted downwards by 0.08 bar (1.2 psi).

DescriptionThe device displays warnings and faults. This is done via IO-Link using the diagnostic
message stored in the device. The purpose of all device diagnostics is solely to provide
information to the user; they do not have a safety function. The errors diagnosed by the
device are displayed via IO-Link in accordance with NE107. In accordance with the
diagnostic message, the device behaves as per a warning or fault condition:
Warning (S971, S140, C485, C431, C432):
With this type of error, the device continues to measure. The output signal does not adopt
its fault state (value in the event of an error). The main measured value and the state in
the form of the letter plus a defined number are displayed alternately (0.5 Hz) via IO-Link.
The switch outputs remain in the state defined by the switch points.
Fault (F437, S803, F270, S510, C469, F804):
With this type of error, the device does not continue to measure. The output signal adopts
its fault state (value in the event of an error). The fault state is displayed via IO-Link in the
form of the letter plus a defined number. The switch output changes to the defined state
(open). For the analog output option, an error is also signaled and transmitted via the 4 to
20mA signal. In NE43, NAMUR defines a current ≤3.6 mA and ≥21 mA as a device failure.
A corresponding diagnostic message is displayed. Current levels available for selection:

PrerequisiteThe following functions are available only if a hysteresis function has been configured for

Description of behavior of
SP1/RP1
The hysteresis is implemented using the SP1 and RP1 parameters. Since the parameter
settings depend on one another, the parameters are described all together.
The switch point "SP1" and switchback point "RP1" can be defined with these functions (e.g.
for pump control). When the set switch point "SP1" is reached (with increasing pressure),
an electrical signal change takes place at the switch output. When the set switchback point
"RP1" is reached (with decreasing pressure), an electrical signal change takes place at the
switch output. The difference between the value of switch point "SP1" and the value of
switchback point "RP1" is known as the hysteresis. The configured value for the switch
point "SP1" must be greater than the switchback point "RP1"! A diagnostic message is
displayed if a switch point "SP1" is entered that is ≤ the switchback point "RP1". While it is
possible to make this entry, it does not take effect in the device. The entry must be
corrected!

PrerequisiteThe following functions are available only if a window function has been configured for

Description of behavior of
FH1/FL1
The window function is implemented using the FH1 and FL1 parameters. Since the
parameter settings depend on one another, the parameters are described all together.
The upper value of the pressure window "FH1" and the lower value of the pressure window
"FL1" can be defined with these functions (e.g., for monitoring a certain pressure range).
When the lower value of the pressure window "FL1" is reached (with increasing or
decreasing pressure), an electrical signal change takes place at the switch output. When
the upper value of the pressure window "FH1" is reached (with increasing or decreasing
pressure), an electrical signal change takes place at the switch output. The difference
between the upper value of the pressure window "FH1" and the lower value of the pressure
window "FL1" is known as the pressure window. The upper value of the pressure window
"FH1" must be greater than the lower value of the pressure window "FL1"! A diagnostic
message is displayed if the upper value entered for the pressure window "FH1" is less than
the lower value of the pressure window "FL1". While it is possible to make this entry, it

16.5.2 Pressure specifications
At +135°C (+275 °F) for a maximum of one hour (device in operation but not within
measuring specification)
WARNING
L
The maximum pressure for the measuring device depends on the lowest-rated
element with regard to pressure.
For pressure specifications, see the "Measuring range" section and "Mechanical
‣
construction" section in the Technical Information.
The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS". The
‣
abbreviation "PS" corresponds to the MWP (maximum working pressure) of the
measuring device.
MWP (maximum working pressure): The MWP (maximum working pressure) is
‣
specified on the nameplate. This value is based on a reference temperature of
+20 °C (+68 °F) and may be applied to the device for an unlimited period of time.
Observe the temperature dependency of the MWP.
OPL (over pressure limit): The test pressure corresponds to the over pressure limit of
‣
the sensor and may only be applied temporarily to ensure that the measurement is
within the specifications and no permanent damage develops. In the case of sensor
range and process connections where the over pressure limit (OPL) of the process
connection is smaller than the nominal value of the sensor, the device is set at the
factory, at the very maximum, to the OPL value of the process connection. If you want
to use the entire sensor range, select a process connection with a higher OPL value.
