Explanation

1 OPL The OPL (over pressure limit = sensor overload limit) for the measuring device

depends on the lowest-rated element, with regard to pressure, of the selected components, i.e. the process connection has to be taken into consideration in addition to the measuring cell. Also observe pressure-temperature dependency. For the relevant standards and additional notes, see the "Pressure specifications" section →  66 . The OPL may only be applied for a limited period of time.

2 MWP The MWP (maximum working pressure) for the sensors depends on the lowest-

rated element, with regard to pressure, of the selected components, i.e. the process connection has to be taken into consideration in addition to the measuring cell. Also observe pressure-temperature dependency. For the relevant standards and additional notes, see the "Pressure specifications" section →  66 . The MWP may be applied at the device for an unlimited period. The MWP can also be found on the nameplate.

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 24-bit chunks.

Bit 0 (LSB) 1 ... 20 21 (MSB) 22 23

Measuring device Pressure value OU1 res.

Bit 23 is reserved. Bit 22 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 22 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 →  26.

For a description of the parameters mentioned and possible error messages, see the "Description of device parameters" section →  43 and →  36.

Performing the configuration

1. Select a pressure unit, here "bar" for example, via the Unit changeover (UNI) parameter. Menu path: Application → Sensor → Unit changeover (UNI)

2. Select Value for 4 mA (STL) parameter. Menu path: Application → Current output (OU2) → Value for 4 mA (STL). 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. Menu path: Application → Current output (OU2) → Value for 20 mA (STU). 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).

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 →  26.

For a description of the parameters mentioned and possible error messages, see the "Description of device parameters" section →  43 and →  36.

Performing the configuration

1. Select a pressure unit, here "bar" for example, via the Unit changeover (UNI) parameter. Menu path: Application → Sensor → Unit changeover (UNI)

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. Menu path: Application → Current output (OU2) → Pressure applied for 4mA (GTL). 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. Menu path: Application → Current output (OU2) → Pressure applied for 20mA (GTU). The selection is confirmed by pressing "Get Lower Limit".

9.4 Performing position adjustment

Zero point configuration (ZRO)

Navigation 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.

Prerequisite An 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 value0.002 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.

Note Setting in increments of 0.001. As the value is entered numerically, the increment

depends on the measuring range

Zero point adoption (GTZ)

Prerequisite The pressure value present is automatically adopted as the zero point.

• be operated by making appropriate corrections to the offset or span.

Raw measured value – (manual offset) = display value (measured value)

Example 1 • Measured value0.002 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.

• If necessary, check and correct switch points and span settings.

Example 2 Sensor 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 value0.08 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 .

9.5.3 Switch output (OU1)

Behavior of switch output

Switch point value / Upper value for pressure window, output 1 (SP1 / FH1) Switchback point value / Lower value for pressure window, output 1 (RP1 / FL1)

Navigation Application → Switch output (OU1) → Switch point value / Upper value for pressure

window, output 1 (SP1 / FH1) Application → Switch output (OU1) → Switchback point value / Lower value for pressure window, output 1 (RP1 / FL1)

Prerequisite The 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!

Prerequisite The 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".

Switching delay

Switching delay time, output 1 (dS1) Switchback delay time, output 1 (dR1)

Note The switching delay time/switchback delay time function is implemented using the dS1

and dR1 parameters. Since the parameter settings depend on one another, the parameters are described all together.

• dS1 = switching delay time, output 1

• dR1 = switchback delay time, output 1

Navigation Application → Switch output (OU1) → Switching delay time, output 1 (dS1)

Application → Switch output (OU1) → Switchback delay time, output 1 (dR1)

Description To 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 from scratch.

Example • SP1 = 2 bar (29 psi)

• RP1 = 1 bar (14.5 psi)

• dS1 = 5 seconds

• dR1 = 2 seconds

dS1/: ≥2 bar (29 psi) must be present for at least 5 seconds for SP1 to become active. dR1/: ≥1 bar (14.5 psi) must be present for at least 2 seconds for RP1 to become active.

1) The switch output is open and the current output adopts the configured alarm current. Therefore, errors affecting the switch output are not displayed since the switch output is in the safe state.

2) The device outputs an error current of 0 mA if an internal communication error occurs. In all other cases the device returns the configured error current.

3) If no remedial measures are taken, the warning messages are displayed following a device restart if configuration (span, switch points and offset) is performed with a gauge pressure device and readings are > URL + 10 % or < LRL + 5 % and with an absolute pressure device and readings are > URL + 10% or < LRL.

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 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).

Zero point configuration (ZRO)

Navigation 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.

Prerequisite An 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 value0.002 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.

Zero point adoption (GTZ)

Navigation Application → Sensor → Zero point adoption (GTZ)

Description (typically gauge 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 need not be known.

Prerequisite The 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 value0.002 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.

• If necessary, check and correct switch points and span settings.

Example 2 Sensor 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 value0.08 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).

Description The 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)

Navigation Application → Current output (OU2) → Pressure applied for 20mA (GTU)

Description The 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.

Description The 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.

Prerequisite The 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!

Prerequisite The 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!

Switching delay

Switching delay time, output 1 (dS1) Switchback delay time, output 1 (dR1)

Note The switching delay time/switchback delay time function is implemented using the dS1

and dR1 parameters. Since the parameter settings depend on one another, the parameters are described all together.

• dS1 = switching delay time, output 1

• dR1 = switchback delay time, output 1

Navigation Application → Switch output (OU1) → Switching delay time, output 1 (dS1)

Application → Switch output (OU1) → Switchback delay time, output 1 (dR1)

Description To 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 from scratch.

Example • SP1 = 2 bar (29 psi)

• RP1 = 1 bar (14.5 psi)

• dS1 = 5 seconds

• dR1 = 2 seconds

dS1/: ≥2 bar (29 psi) must be present for at least 5 seconds for SP1 to become active. dR1/: ≥1 bar (14.5 psi) must be present for at least 2 seconds for RP1 to become active.

For further information please contact your local Endress+Hauser Sales Center.

16.5.2 Pressure specifications

L

WARNING

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.
