directives listed in the device-specific EU Declaration of Conformity. Endress+Hauser
confirms this by affixing the CE mark to the device.
Devices with ceramic process isolating diaphragm (Ceraphire®)
The ceramic sensor is an oil-free sensor, i.e. the process pressure acts directly on the
robust ceramic process isolating diaphragm and causes it to deflect. A pressure-dependent
change in capacitance is measured at the electrodes of the ceramic substrate and the
process isolating diaphragm. The measuring range is determined by the thickness of the
ceramic process isolating diaphragm.
Devices with metallic process isolating diaphragm
The process pressure deflects the metal process isolating diaphragm of the sensor and a fill
fluid transfers the pressure to a Wheatstone bridge (semiconductor technology). The
pressure-dependent change in the bridge output voltage is measured and evaluated.

6.3.1 Load (for devices with analog output)
In order to guarantee sufficient terminal voltage, a maximum load resistance RL (including
line resistance) must not be exceeded depending on the supply voltage UB of the supply
unit.
The maximum load resistance depends on the terminal voltage and is calculated according
to the following formula:
1)100 mA can be guaranteed over the entire temperature range for the switch outputs "2 x PNP" and "1 x PNP + 4 to 20 mA output". For lower
ambient temperatures, higher currents are possible but cannot be guaranteed. Typical value at 20 °C (68 °F) approx. 200 mA. 200 mA can be
guaranteed over the entire temperature range for the "1 x PNP" current output.
2)Larger currents are supported, thus deviating from the IO-Link standard.
• failure current is output and "S803" displayed (output: MIN alarm current)
• Periodic checking to establish if it is possible to quit fault state
• In order to guarantee sufficient terminal voltage, a maximum load resistance RL
(including line resistance) must not be exceeded depending on the supply voltage UB of
the supply unit.

7.1.2 Operating concept
Operation with an operating menu is based on an operation concept with "user roles" .
User roleMeaning
Operator
(display level)
Maintenance
(user level)
Operators are responsible for the devices during normal "operation". This is usually limited to
reading process values either directly at the device or in a control room. Should an error occur,
these users simply forward the information on the errors but do not intervene themselves.
Service engineers usually work with the devices in the phases following device commissioning.
They are primarily involved in maintenance and troubleshooting activities for which simple
settings have to be made on the device. Technicians work with the devices over the entire life
cycle of the product. Thus, commissioning and advanced settings and configurations are some
of the tasks they have to carry out.
DIAGContains all the parameters that are needed to detect and analyze
Contains all the parameters that are needed to commission
measuring operations. A wide range of parameters, which can be
used to configure a typical application, is available at the start. After
making settings for all these parameters, the measuring operation
should be completely configured in the majority of cases.
parameters which allow more accurate configuration of the
measurement, conversion of the measured value and scaling of the
output signal.
operating errors.
7.2 Operation with local display
7.2.1 Overview
A 1-line liquid crystal display (LCD) is used for display and operation. The local display
shows measured values, fault messages and information messages and therefore supports
the user through each operating step.
The display is fixed to the housing and can be electronically rotated 180° (see parameter
description for "DRO" → 73). This ensures optimum readability of the local display and
allows the device to be mounted upside down also.
During measuring operation, the display shows measured values, fault messages and
notice messages. In addition, it is possible to switch to menu mode via the operating keys.

Enter the desired value with the or key and press the key to confirm. Following
confirmation, the data are recorded directly and are active.
– Entry is OK: value is accepted and shown for one second on the display against a white
background.
– Entry is not OK: the message "FAIL" appears for one second on the display against a red
background. The value entered is rejected. In the event of an incorrect setting which
affects the TD, an diagnostic message is displayed.
7.4 Navigation and selection from list
The capacitive operating keys are used for navigation in the operating menu and to select
an option from a picklist.
Operating key(s)Meaning
• Navigate downwards in the picklist
A0017879

• Select a menu item and activate the edit mode
• The key lock function (KYL) is accessed by pressing the key for longer than 2 seconds
Key locking is indicated on the local display by "E > 2".
Locking of the parameter settings is indicated as soon as an attempt is made to change a
parameter.
7.5.1 Disabling the key lock
The keys are locked automatically if the device remains at the topmost menu level (display
of pressure measurement value) for 60 seconds.
Call up the key lock function (KYL)
1.Press the key for at least 2 seconds and then release it
2.By confirming with "ON" is displayed
3.Use and to toggle between "ON" and "OFF"
4.Key locking is disabled as soon as is pressed to confirm "OFF"
The display changes to the main value level (topmost menu level) if the key is pressed
briefly. The display changes to the key locking if the key is pressed for at least 2
seconds.
If in the case of "KYL", "ON" or "OFF", more than 10 seconds elapse without a key being
pressed, you return to the topmost menu level with active key locking.
The function can be accessed anytime outside the main measured value display and within
the operating menu, i.e. if the key is pressed for at least 2 seconds key locking can be
performed anytime at any menu item. Locking is effective immediately. If you quit the
context menu, you will return to the same point from which key locking was selected.
7.5.2 Locking and unlocking parameter settings
The device settings can be protected from unauthorized access.
COD parameter: define the locking code
0000Device is permanently unlocked (factory setting)
0001-9999Device is locked
LCK parameter: unlock parameter locking (enter the COD)
If parameters are locked, the word "LCK" appears on the local display as soon as an attempt
is made to change a parameter.
Examples:
Locking the device with a customer-specific code
1.EF → ADM → COD
2.Enter a COD not equal to 0000 (value range: 0001 to 9999)
3.Wait 60 seconds or restart the device
4.Parameters are locked (protected against changes)

The measuring device has one current output and one or two switch outputs (depending
on the version ordered). The status of the switch outputs and the pressure value are
transmitted in the form of process data via IO-Link.
• In the SIO mode, the switch output is switched at pin 4 of the M12 plug. In the IO-Link
communication mode, this pin is reserved exclusively for communication.
• If the "with current output" option is ordered, the current output at pin 2 of the M12 plug
is always active or can optionally be deactivated via IO-Link or at the display or
configured as DC-PMP.
• The device's process data are transmitted cyclically in 32-bit chunks.

8.2 Reading out and writing device data (ISDU – Indexed
Service Data Unit)
Device data are always exchanged acyclically and at the request of the IO-Link master.
Using the device data, the following parameter values or device statuses can be read out:
If an existing configuration is changed, measuring operation continues! The new or
modified entries are only accepted once the setting has been made.
If block parameterization is used, a parameter change is only adopted after the parameter
download.
WARNING
L
Risk of injury from the uncontrolled activation of processes!
Make sure that downstream processes are not started unintentionally.

NOTICE
An IO-DD with corresponding default values is used for all pressure measuring
ranges. This IO-DD applies for all measuring ranges! The default values of this IO-DD
can be inadmissible for this device. IO-Link messages (e.g. "Parameter value above
limit") may be displayed when the device is updated with these default values.
Existing values are not accepted in this case. The default values apply exclusively to
the 10 bar (150 psi) sensor.
The data must first be read out of the device before default values are written from the

IO-DD to the device.
9.1 Function check
Before commissioning your measuring point, ensure that the post-installation and postconnection check have been performed:
• "Post-installation check" checklist → 19
• "Post-connection check" checklist
9.2 Commissioning with an operating menu
Commissioning comprises the following steps:
• Configure pressure measurement → 36
• Where applicable, perform position adjustment → 38
• Where applicable, configure process monitoring → 40
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 → 38.
For a description of the parameters mentioned and possible error messages, see the
"Description of device parameters" section → 56 and → 44.
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).
9.3.2 Calibration with reference pressure (wet calibration =
calibration with 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:
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 → 38.
For a description of the parameters mentioned and possible error messages, see the
"Description of device parameters" section → 56 and → 44.
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) parameter.
The selection is confirmed by pressing "Get Lower Limit".
The pressure value present is assigned to the upper current value (20 mA).
The measuring range is configured for 0 to 300 mbar (0 to 4.4 psi).

Description(typically absolute pressure sensor)
The pressure resulting from the orientation of the device can be corrected here.
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 mbar (0.029 psi)
• Set the measured value in the parameter to 0.002.
• Measured value (after pos. zero adjust) = 0.000 mbar (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

Zero point adoption (GTZ)
NavigationDisplay: EF → Zero point adoption (GTZ)
IO-Link: Parameter → Application → Sensor → Zero point adoption (GTZ)
Description(typically gauge pressure sensor)
The pressure resulting from the orientation of the device can be corrected here.
The pressure difference between zero (set point) and the measured pressure need not be
known.
PrerequisiteThe pressure value present is automatically adopted as the zero point.
An offset is possible (parallel shifting of the sensor characteristic) to correct the
orientation and any zero point drift. The accepted 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 1• Measured value = 0.002 mbar (0.029 psi)
• Use the Zero point adoption (GTZ) parameter to correct the measured value with the
value, e.g. 0.002 mbar (0.029 psi). This means that you are assigning the value 0.000 (0
psi) to the pressure present.
• Measured value (after pos. zero adjust) = 0.000 mbar (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.
• Measured value (after pos. zero adjust) = 0 mbar (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).
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 → 44.
– 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 → 44.
DescriptionThe pressure value present is automatically adopted for the 4 mA current signal.
Parameter for which the current range can be assigned to any section of the nominal
range. This occurs by assigning the pressure lower range value to the lower measuring
current and the pressure upper range value to the upper measuring current.
The pressure lower range value and upper range value can be configured independently of
one another so the pressure measuring span does not remain constant.
The LRV and URV pressure measuring span can be edited over the entire sensor range.
An invalid TD value is indicated by diagnostic message S510. An invalid position offset is
indicated by diagnostic message C431.
The editing operation cannot result in the device being operated outside the minimum and
maximum sensor limits.
Incorrect entries are declined as indicated by the following messages, and the last valid
value prior to the change is used again:
• Parameter value above limit (0x8031)
• Parameter value below limit (0x8032)
The measured value currently present is accepted as the value for 4mA anywhere within
the measuring range.
The sensor characteristic curve is shifted such that the pressure present becomes the zero
value.
Pressure applied for 20mA (GTU)
NavigationDisplay: EF → I → Pressure applied for 20mA (GTU)
IO-Link: Parameter → Application → Current output → Pressure applied for 20mA (GTU)
DescriptionThe pressure value present is automatically adopted for the 20 mA current signal.
Parameter for which the current range can be assigned to any section of the nominal
range. This occurs by assigning the pressure lower range value to the lower measuring
current and the pressure upper range value to the upper measuring current.
The pressure lower range value and upper range value can be configured independently of
one another so the pressure measuring span does not remain constant.
The LRV and URV pressure measuring span can be edited over the entire sensor range.
An invalid TD value is indicated by diagnostic message S510. An invalid position offset is
indicated by diagnostic message C431.
The editing operation cannot result in the device being operated outside the minimum and
maximum sensor limits.
Incorrect entries are declined, and the last valid value prior to the change is used again.
The measured value currently present is accepted as the value for 20 mA anywhere within
the measuring range.
There is a parallel shift of the sensor characteristic so that the pressure present becomes
the max value.
Example: The compressor is started when the pressure drops below a certain value. The
compressor is switched off when a certain value is exceeded.
1.Set the switch point to 2 bar (29 psi)
2.Set the switchback point to 1 bar (14.5 psi)
3.Configure the switch output as an "NC contact" (HNC function)
The compressor is controlled by the defined settings.
9.7.2 Pump control with hysteresis function
Example: The pump should switch on when 2 bar (29 psi) is reached (increasing pressure)
and switch off when 1 bar (14.5 psi) is reached (decreasing pressure).
1.Set the switch point to 2 bar (29 psi)
2.Set the switchback point to 1 bar (14.5 psi)
3.Configure the switch output as an "NO contact" (HNO function)
The pump is controlled by the defined settings.

10.3 Behavior of the device in the event of a fault
The device displays warnings and faults via I/O-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. In accordance with the
diagnostic message, the device behaves as per a warning or fault condition. It is necessary
to distinguish between the following types of errors here:
• Warning:
– The device continues measuring if this type of error occurs. The output signal is not
affected (exception: simulation is active).
– The local display alternates between the warning and the main measured value.
– The switch outputs remain in the state defined by the switch points.
– The status LED flashes red (not for IO-Link).
– The background remains white in the event of a warning
• 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 fault state is indicated on the local display.
– The switch outputs assume the "opened" state.
– For the analog output option, an error is signaled with the configured alarm current
behavior.
10.4 Signal on alarm 4 to 20 mA
The response of the output to error 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)→ 62
• Alarm current FCU "MAX" (factory setting): Upper alarm current (≥21 mA)→ 62
• Alarm current FCU "HLD" (HOLD) (optional, see the following table): Last measured
current value is held. When the device starts, the current output is set to "Lower alarm
current" (≤3.6 mA). → 62
• The selected alarm current is used for all errors.
• Errors and warning messages are displayed via IO-Link.
• Errors and warning messages are displayed only on the primary value page
(topmost display level) and are not displayed in the operating menu.
• In the operating menu the error is only indicated by the color of the display
background.
• The status LED always indicates an error.
• 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).
Changing the failsafe modeAfter confirming with

10.5 Behavior of the device in the event of a voltage drop
A diagnostic message is not output. The configuration and the settings made are retained.
10.6 Behavior of the device in the event of an incorrect
entry
In the case of incorrect entries, the value entered is not accepted. No fault or warning is
issued in this case. The value to be adjusted cannot be changed to a value outside the
specified limit. This makes it impossible to configure the device using incorrect values. An
exception to this is the configuration of the span that results in a violation of the turn
down, which in turn gives rise to a fault state.
10.7 Resetting to factory settings (reset)
See Reset to factory settings (RES) parameter description→ 71.
11 Maintenance
No special maintenance work is required.
Keep the pressure compensation element (1) free from contamination.
Please note the following points when cleaning the device:
• The cleaning agents used should not corrode the surface and the seals.
• Mechanical damage to the process isolating diaphragm, e.g. due to sharp objects, must
be avoided.
• Observe the degree of protection of the device. See the nameplate if necessary → 14.

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 visual warning is indicated on the local display
(C485 - Simulation active) and a warning is communicated via IO-Link (C485 - Simulation

Description(typically absolute pressure sensor)
The pressure resulting from the orientation of the device can be corrected here.
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 mbar (0.029 psi)
• Set the measured value in the parameter to 0.002.
• Measured value (after pos. zero adjust) = 0.000 mbar (0 psi)
• The current value is also corrected.

PrerequisiteThe pressure value present is automatically adopted as the zero point.
An offset is possible (parallel shifting of the sensor characteristic) to correct the
orientation and any zero point drift. The accepted 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 1• Measured value = 0.002 mbar (0.029 psi)
• Use the Zero point adoption (GTZ) parameter to correct the measured value with the
value, e.g. 0.002 mbar (0.029 psi). This means that you are assigning the value 0.000 (0
psi) to the pressure present.
• Measured value (after pos. zero adjust) = 0.000 mbar (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.
• Measured value (after pos. zero adjust) = 0 mbar (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:
The selected alarm current is used for all errors. Diagnostic messages are displayed with
numbers and letter via IO-Link. It is not possible to acknowledge all the diagnostic
messages. The relevant message disappears if the event is no longer pending.
The messages are displayed in order of priority:
• Highest priority = first message displayed
• Lowest priority = last message displayed

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

Description
WARNING
L
Confirming the "Standard Command" with "Reset to factory settings" causes an
immediate reset to the factory settings of the order configuration.
If the factory settings have been changed, downstream processes might be affected
following a reset (the behavior of the switch output or current output might be changed).
Make sure that downstream processes are not started unintentionally.
‣
The reset is not subject to additional locking, such as in the form of device locking. The
reset also depends on the device status.
Any customer-specific configuration carried out at the factory is not affected by a reset
(customer-specific configuration remains).
The following parameters are not reset when a reset is performed:
• LO Min value (minimum indicator)
• HI Max value (maximum indicator)
• Last Diagnostic (LST)
• Revisioncounter (RVC)

The maximum load resistance depends on the terminal voltage and is calculated according
to the following formula:
3)100 mA can be guaranteed over the entire temperature range for the switch outputs "2 x PNP" and "1 x PNP + 4 to 20 mA output". For lower
ambient temperatures, higher currents are possible but cannot be guaranteed. Typical value at 20 °C (68 °F) approx. 200 mA. 200 mA can be
guaranteed over the entire temperature range for the "1 x PNP" current output.
4)Larger currents are supported, thus deviating from the IO-Link standard.

Applications with changes in temperature
Frequent extreme changes in temperatures can temporarily cause measuring errors.
Temperature compensation takes place after a few minutes. Internal temperature
compensation is faster the smaller the change in temperature and the longer the time
interval.

17.6.3 Pressure specifications
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.
Devices with ceramic process isolating diaphragm: avoid steam hammering! Steam
‣
hammering can cause zero point drifts. Recommendation: Residue (water droplets or
condensation) may remain on the process isolating diaphragm following CIP cleaning
and can result in local steam hammering the next time steam cleaning takes place. In
practice, drying the process isolating diaphragm (e.g. by blowing) has proved to prevent
steam hammering.
