Devices which support the HART protocol are classified as either operating devices or field devices. When it comes to operating devices (Master), both manual control units (Secondary Master) and PC-supported workstations (Primary Master) are used in, for example, a control centre. HART field devices include flow sensors, signal converters and actuators. The field devices range from 2-wire to 4-wire to intrinsically safe versions for use in hazardous areas. The HART data are superimposed over the analogue 4...20 mA signal via FSK modem. This way, all of the connected devices can communicate digitally with one another via the HART protocol while simultaneously transmitting the analogue signals. When it comes to the field devices and secondary masters, the FSK or HART modem is integrated, whereas with a PC communication takes place via an external modem which must be connected to the serial interface. There are, however, other connection variants which can be seen in the following connection diagrams. 9.2 Software history INFORMATION!

It follows that the dynamic variables connected to current or frequency outputs can only be assigned to the linear HART device variables. The HART dynamic variable PV is always connected to the HART current output. A totaliser device variable can thus not be assigned to the dynamic variable PV because the PV is always connected to the HART current output. Such correlations do not exist for dynamic variables not connected to linear analogue outputs. Both linear and totaliser device variables can be assigned. The totaliser device variables can only be assigned to the dynamic variables SV, TV and 4V if the connected output is not a current or frequency output. 01/2021 - 4002075808 - MA MFC400 ER2.1 R08 en www.krohne.com 139 10 DESCRIPTION OF BLUETOOTH INTERFACE MFC 400 The signal converter is optionally equipped with a Bluetooth interface. This interface provides wireless access to the signal converter for convenient parametrisation and service diagnosis via standard mobile devices, such as smartphones or tablet computers. The interface is accessed by the KROHNE OPTICHECK Flow Mobile app, which is available for Google Android and Apple iOS operation systems. 10.1 Introduction 10.1.1 Functionality The OPTICHECK Flow Mobile app offers the following functionality:

Bluetooth can be enabled even if the device is in SIL mode. For detailed information refer to the "Safety manual". Note the following restrictions:

Activation or deactivation of the SIL mode is not possible via the Bluetooth interface. SIL-relevant parameters cannot be changed once the device is in SIL mode. 01/2021 - 4002075808 - MA MFC400 ER2.1 R08 en www.krohne.com 141 10 DESCRIPTION OF BLUETOOTH INTERFACE MFC 400 10.3 Field device setup The Bluetooth interface is an optional feature and must be purchased before it can be used. Please contact your sales representative on information how to order and activate the Bluetooth feature, if it is not yet available. For security reasons, the Bluetooth interface must be parametrised and enabled locally at the field device before a connection is possible. Once enabled successfully, the Bluetooth interface state is indicated in the header line of the local display (for details refer to Display and operating elements on page 54). The following steps are necessary for the initial setup of the Bluetooth interface:

1. Set the maximum access level via the mechanical switch (for details refer to Bluetooth access level setting via mechanical switch on page 143). 2. Further limit the access level via a software setting (for details refer to Bluetooth access level setting via software (C8.1.0 Access Level) on page 144). 3. Look up or modify the password for the Bluetooth interface (for details refer to Password for the Bluetooth interface (C8.2.0 Password) on page 144). 10.3.1 Bluetooth access level The Bluetooth access level is used to limit the remote access to the field device via the Bluetooth interface. The following access levels can be selected:

Access level Description No access Read only Read + Write The Bluetooth interface is disabled. No connection is possible. The Bluetooth interface is enabled. Parameters of the field device can be read. Parameter changes are not possible. The Bluetooth interface is enabled. Reading and modification of field device parameters are possible. Table 10-1: Access levels for the Bluetooth interface The access level is set by two mechanisms: A mechanical switch and a software setting. The mechanical switch is located at the backside of the display and can be operated only when the housing of the signal converter is opened. The setting of the mechanical switch takes precedence over the software setting and provides high security for use cases, in which access via the Bluetooth interface must be limited. 142 www.krohne.com 01/2021 - 4002075808 - MA MFC400 ER2.1 R08 en MFC 400 DESCRIPTION OF BLUETOOTH INTERFACE 10 Mechanical switch (switch position) Software setting Resulting access level No access (OFF) Read only (R/-) Read + Write (R/W) No access No access Read only No access Read only No access 1 No access Read only No access Read only Table 10-2: Access level selection via mechanical switch and software settings Read + Write Read + Write 1 If the mechanical switch is in the OFF position, the Bluetooth interface is disabled by a hardware mechanism. No activation via software is possible. It is recommended to set the mechanical switch to the most permissive level which is acceptable for the application. Further limitations can be performed via software settings without opening the field device housing. Note that application specific locks (for details refer to Locking of configuration on page 100) have a higher priority than the access level of the Bluetooth interface and will prevent any modification of locked parameters, even though the access level "Read + Write" is selected. 10.3.2 Bluetooth access level setting via mechanical switch The mechanical switch is the primary method to define the access level. It is located at the back of the display. To change the position of the mechanical switch, the housing of the signal converter must be opened, and the display must be detached (for details refer to Turning the display of the field housing version on page 21). Figure 10-1: Position of mechanical switch 1 "OFF" position: No access 2 "R/-" position: Read only 3 "R/W" position: Read + Write 01/2021 - 4002075808 - MA MFC400 ER2.1 R08 en www.krohne.com 143 10 DESCRIPTION OF BLUETOOTH INTERFACE MFC 400 10.3.3 Bluetooth access level setting via software (C8.1.0 Access Level) The access level can be further limited by a software setting in menu C8.1.0. The available options depend on the position of the mechanical switch. For details refer to previous section. INFORMATION!

The software setting may change when the mechanical switch is operated. Therefore, the position of the mechanical switch must be selected before the access is further limited via the software setting. 10.3.4 Password for the Bluetooth interface (C8.2.0 Password) The password for the Bluetooth interface is used for authentication of the wireless connection and must be entered in the mobile device to establish a connection to the field device. The password must be kept secret and must only be known by authorised personnel. Each device is shipped with a unique and randomly generated password. The initial password can be looked up by navigating to the menu C8.2.0 (Password). If necessary, the initial password can be changed by entering a new password in menu C8.2.0. The password must comply to the following rules:

Alphanumeric characters (az, AZ, 09) in addition to the letters ., /, -, _, and Minimum length: 4 characters Maximum length: 16 characters Trailing whitespaces are ignored (i.e. spaces after the last character are not part of the password) Note that the write access authentication level "Operator" (for details refer to Locking of configuration on page 100) is required to view or modify the Bluetooth password via the local display. Enabling the write access authentication therefore protects the password against unauthorised lookup or modification locally at the device. For security reasons, it is strongly recommended:

Select a unique password for each device. Set a sufficiently strong password according to your company security guidelines (e.g. at least 8 characters, combination of letter and numbers). Do not use passwords which can be guessed easily, or which can be found in a dictionary. Only grant knowledge of the password to authorised personnel. Change the password immediately if there is reason to suspect that unauthorised personnel have gained knowledge of the password. 144 www.krohne.com 01/2021 - 4002075808 - MA MFC400 ER2.1 R08 en MFC 400 DESCRIPTION OF BLUETOOTH INTERFACE 10 10.3.5 LED Signalling (C8.3.0) The connection status of the Bluetooth interface can be signalled via the MS (S1) LED on the local display (for details refer to Display and operating elements on page 54). The functionality can be turned on and off by menu C8.3.0. The LED signalling for the Bluetooth interface may not be available for all signal converter configurations. If the LED signalling is enabled, the Bluetooth connection status is indicated via the MS (S1) LED:

MS (S1) LED Blink pattern Description Off Blue Blue Blue

Constant on Bluetooth interface turned off Bluetooth interface enabled, ready for connection Fast blinking (1 Hz) Bluetooth interface connected, read & write mode Slow blinking (0.5 Hz) Bluetooth interface connected, read-only mode Table 10-3: Status indication 10.3.6 Reset Bluetooth lockout (A2.7.0, C8.4.0) The Bluetooth connectivity is temporarily disabled in case of a failed authentication. This can happen if a wrong password was entered and prevents brute-force attacks by iterating over all possible passwords. The duration of the lockout increases with the number of consecutively failed authentications

(range: 1 s1 h). After 10 authentications have failed in a row, the Bluetooth interface is disabled permanently and must be unlocked at the signal converter. If the device is in a temporary or permanent lockout phase, the lockout can be removed immediately by one of the following actions:

"Reset BT Lockout" via menu (A2.7.0, C8.4.0).

"Reset all Errors" (A2.1.0, C6.2.0). Note that this may also reset other errors in the device. Power cycling the signal converter. 01/2021 - 4002075808 - MA MFC400 ER2.1 R08 en www.krohne.com 145 10 DESCRIPTION OF BLUETOOTH INTERFACE MFC 400 10.3.7 Check Bluetooth connection status (B1.7.1) The status of the Bluetooth interface is displayed in detail in menu B1.7.1:

Connection status Description Off Advertising Connected Lockout Bluetooth interface turned off. Bluetooth interface is enabled and ready for connection. Bluetooth interface connected. Bluetooth is temporarily or permanently disabled due to failed authentications

(for details refer to Reset Bluetooth lockout (A2.7.0, C8.4.0) on page 145). Table 10-4: Status of the Bluetooth interface 10.3.8 Login history (B1.7.2, B1.7.3) The date and time of the last successful and the last failed authentication attempts are displayed via menu B1.7.2 (last successful authentication) and B1.7.3 (last failed authentication). If there was no authentication attempt, a "Value invalid" message is displayed. The information can be useful to check if there have been unexpected login attempts via Bluetooth. Note that the login history is reset when a power cycle of the device is performed. 10.4 Installation of the OPTICHECK Flow Mobile app The OPTICHECK Flow Mobile app is available for supported devices via "Google Play store"

and "Apple App Store". Perform the following steps for installation:

Ensure your mobile device is connected to the internet. Open the app store (e.g. "Google Play store" on Android devices or "App Store" on Apple devices) Type "KROHNE OPTICHECK Flow Mobile" in the search field.

Finalise the installation before performing zero calibration. Changes (pipe system or calibration factor) made after the zero calibration may affect the accuracy, making it necessary to perform zero calibration again. Observe the following for reliable zero calibration:

The flow sensor should be completely filled with the product at the expected process pressure and temperature. The product may contain no air or gas, especially when it comes to horizontal installations. Prior to zero calibration, it is recommended that the product be flushed at a high flow rate

(>50%), for 2 minutes. After flushing, re-establish zero flow by closing off the corresponding valves. Set zero calibration automatically or manually using the operating controls. The signal converter cover must be installed on the display for automatic calibration.

Log information includes zero offset, temperature, date and time. Navigate using the and keys. Exit the menu using the ^ key. Under certain conditions, zero calibration is not possible and will be cancelled:

The product is still flowing. The shut-off valves are not closed tightly enough. There are still gas bubbles in the flow sensor. Remedy: Flush flow sensor and repeat calibration With some media, it may be difficult to perform zero calibration. In such cases, there are various methods to still achieve good zero calibration:

Medium Possible solutions Media that tend to evaporate or outgas Increase pressure. Two-phase media (slurries), that contain solids that may fall out. Only fill the flow sensor with the carrier medium. Fill flow sensor with another liquid, e.g. water. Two-phase media in which the solids or gas-

forming components cannot be separated.

Density calibration is based on 2 calibration points. In the factory, air and water are used under reference conditions. The result of this calibration is saved in the signal converter electronics and stored in the factory settings. Regardless, various applications require maximum accuracy which can only be achieved with on-site calibration. Option Explanation 1 Point Calibration One of the 2 saved calibration points is replaced by customer calibration. The signal converter decides which of the 2 calibration points is modified. 2nd Calibration Point Calibration of the 2nd point. Factory Calibration The signal converter reactivates the factory settings for the density calibration.

Ensure that the device has been properly installed and functions smoothly. If air (empty) is used as the medium, the measuring tube must be completely dry and free of liquids and solids. If possible, blow dry air into the measuring tube to empty it. If liquids are used, flush for a few minutes at a high flow rate to remove gas bubbles. Set the flow rate to a typical value (50% of the nominal flow is ideal). If the process temperature is higher than the ambient temperature, wait until the system has stabilised. When it comes to 1 point and 2 point calibration, you can choose from the options "Empty",

"Pure Water", "Town Water" and "Other". The reference values for the specified products are stored in the signal converter. The reason for "Density Calib. Error" display may be indicated on the screen. Other possible reasons include:

The device is not in "Measurement" mode. The calibration points are too close together. One or more calibration points did not pass the plausibility test. Flow, pressure, temperature or system are not stable. Please check your system and try again. If this or other calibration error display recurs, please contact the manufacturer. 1 Point Calibration Refer to examples for "Calibration with town water and other". Select the function using and and then confirm with ^. If "Other" is selected, the product density must be entered. 1 point calibration is generally sufficient for most applications, such as adapting the density measurement to a new installation. Make sure that prior to calibrating the 2nd point that 1 point calibration was carried out and that the result was saved with the dialog "Save Configuration?". 2 Point Calibration In this case, both reference points are recalibrated (with the products of the system). With 2 point calibration, ensure that both calibration points entered by the user are accepted. If the 2nd point cannot be calibrated immediately after the first one, because the 2nd product is not yet available, the device continues to function normally as after the 1 point calibration. In other words, there can be weeks or even months between the calibration of the two measuring points. 01/2021 - 4002075808 - MA MFC400 ER2.1 R08 en www.krohne.com 87 6 OPERATION MFC 400 6.4.3 Temperature/density tables Temperature Density Temperature Density C 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 F 32 33.8 35.6 37.4 39.2 41 42.8 44.6 46.4 48.2 50 51.8 53.6 55.4 57.2 59 60.8 62.6 64.4 66.2 68 69.8 71.6 73.4 75.2 77 78.8 80.6 82.4 84.2 86 87.8 89.6 kg/m3 lb/ft3 999.8396 62.41999 999.8986 62.42367 999.9399 62.42625 999.9642 62.42777 999.972 62.42825 999.9638 62.42774 999.9402 62.42627 999.9016 62.42386 999.8482 62.42053 999.7808 62.41632 999.6997 62.41125 999.6051 62.40535 999.4975 62.39863 999.3772 62.39112 999.2446 62.38284 999.0998 62.3738 998.9432 62.36403 998.7752 62.35354 998.596 62.34235 998.4058 62.33047 998.2048 62.31793 997.9934 62.30473 997.7716 62.29088 997.5398 62.27641 997.2981 62.26132 997.0468 62.24563 996.7861 62.22936 996.5159 62.21249 996.2368 62.19507 995.9487 62.17708 995.6518 62.15855 995.3462 62.13947 995.0322 62.11986 C 0.5 1.5 2.5 3.5 4.5 5.5 6.5 7.5 8.5 9.5 10.5 11.5 12.5 13.5 14.5 15.5 16.5 17.5 18.5 19.5 20.5 21.5 22.5 23.5 24.5 25.5 26.5 27.5 28.5 29.5 30.5 31.5 32.5 F 32.9 34.7 36.5 38.3 40.1 41.9 43.7 45.5 47.3 49.1 50.9 52.7 54.5 56.3 58.1 59.9 61.7 63.5 65.3 67.1 68.9 70.7 72.5 74.3 76.1 77.9 79.7 81.5 83.3 85.1 86.9 88.7 90.5 kg/m3 lb/ft3 999.8712 62.42197 999.9213 62.42509 999.9542 62.42714 999.9701 62.42814 999.9699 62.42812 999.954 62.42713 999.9227 62.42517 999.8766 999.8162 62.4223 62.4185 999.7419 62.41389 999.6541 62.40840 999.5529 62.40209 999.4389 62.39497 999.3124 62.38708 999.1736 62.37841 999.0229 62.36901 998.8607 62.35887 998.687 62.34803 998.5022 62.3365 998.3066 62.32428 998.1004 62.31141 997.8838 62.29788 997.6569 62.28372 997.4201 62.26894 997.1736 62.25355 996.9176 62.23757 996.6521 62.22099 996.3774 62.20384 996.0939 62.18614 995.8013 62.16788 995.5001 62.14907 995.1903 62.12973 994.8721 62.10987 88 www.krohne.com 01/2021 -

If "Forwards" is selected, the flow direction corresponds to the "+" arrow and with

"Backwards" the flow direction corresponds to the "-" arrow on the housing. Process noise damping (C1.1.5 Process Noise Damping) The flow and density measurements are filtered in order to reduce process noise. The time constant of this filter can be changed in C1.1.5. If you require a faster response of the device, e.g. for short batches, you could reduce this time. This parameter is only available if the device is switched to expert mode (C6.4.5). Low flow cutoff (C1.1.6 Low Flow Cutoff) The flow sensor provides a low flow cutoff (C1.1.6) which is a percentage value of nominal mass flow rate. The nominal mass flow rate is available in menu "Test" (B4.6.0). The low flow cutoff is enabled by default sets all flow measurement variables to zero when the flow is below the low flow cutoff value entered. This parameter is only available if the device is switched to expert mode (C6.4.5). 01/2021 - 4002075808 - MA MFC400 ER2.1 R08 en www.krohne.com 91 6 OPERATION MFC 400 Pressure suppression (C1.1.7 & C1.1.8) The pressure suppression eliminates any disruption in the measurement in the event of an abrupt flow switch-off e.g. when valves are suddenly closed. In such cases, surges may occur in the pipe and in the measuring device which could lead to over-vibration. The flow then "swings"

back and forth before a stable zero flow is established, as shown in the figure below. This effect occurs mainly in high pressure applications. Figure 6-6: Vibration behaviour during pressure suppression 1 Flow switched off 2 Sinusoidal vibration ("over-vibration") 3 Stable zero flow The pressure suppression function eliminates this effect by activating a larger low flow cutoff threshold for a programmable period of time. The pressure suppression is activated when the flow falls below the standard low flow cutoff level for the first time (C1.1.6). For a programmable period of time (C1.1.8), the pressure suppression threshold is added to the standard low flow threshold (C1.1.7). This parameter is only available if the device is switched to expert mode (C6.4.5). Measurement of flow velocity The signal converter can provide the flow velocity based on a pipe diameter which the operator can freely program (C1.1.9). This value can either be the inner diameter of the measuring tube

(factory setting) or the inner diameter of the process pipe. 92 www.krohne.com 01/2021 - 4002075808 - MA MFC400 ER2.1 R08 en MFC 400 OPERATION 6 6.5.2 Density (C1.2.0 Density) Density mode (C1.2.2 Density Mode) There are 4 available operating modes for density that can be set here:

The device provides a signal which indicates two phase flow. This signal can be used for signalling two phase flow according to NE 107 or for approximating the amount of entrained gas. The signal depends on the amount, distribution and size of the entrained gas and therefore any threshold has to be adapted on the application.

The damping can be individually set for each output by a time constant. However, keep in mind that the degree of filtration affects the response time of the device in the event of rapid changes. The general behaviour of the damping value is:

6.6 I/O configuration 6.6.1 Damp output signals Small damping:

- Fast response times

- Fluctuating reading Large damping:

- Slow response time

- Stable reading The damping corresponds to the elapsed time until 63% of the end value has been reached according to a step function. The time until 90% of the end value is reached in case of a step response is T90 = * 1.8 ( = damping). 6.6.2 Suppress small flow rates All digital and analogue outputs provide a low flow cutoff for flow measurements in order to suppress small flow rates. If the low flow cutoff has been activated, the respective output is set to zero when the flow is below the low flow cutoff value entered. The value can be entered as a percentage of the upper range value or in the case of a pulse output as a discrete flow value. Two values must be entered. The first is for the operating point of the flow sensor and the second is for hysteresis.

Be careful with this function because this process cannot be reverted. 6.8.3 Change log (B1.2.0 Change Log) Any configuration change of the signal converter is logged within a change log (B1.2.0) with date and time and a checksum of the signal converter configuration. The change log covers all device parameters (incl. factory parameters) and provides 128 entries. 6.8.4 Locking of configuration Access authentication The signal converter has a multilevel access authentication concept which allows to protect the entire configuration against unauthorised write accesses. The access authentication is disabled by default, however can be enabled by setting an operator password that is not equal to 0000. In case of an enabled access authentication, write accesses via any interface (local display, HART, OPTICHECK, ) can only be performed after authentication by entering the respective access level password (refer to next table). Entering this password only unlocks the currently used interface but no other interfaces. Level Description Authentication User / Free No authentication necessary. Operator Operator password (C6.3.4 Set Operator Password) or no authentication necessary if operator password not set (0000). 0 1 2 Service Service password. Remove jumper.

For this purpose the signal converter provides an application specific lock which can be enabled by a jumper. The lock mechanism can be configured before applying the jumper in order to lock only CT relevant functions and parameters. The following table shows the locking combinations which can be selected in C6.3.6 and the respective locked functionalities and parameters:

Pressing the "^" key for 2.5 seconds carries out the "Quick Access" function. Date and time (C6.4.1 Set Date and Time) The signal converter has a real time clock which is used for all of the log functions in the device. This function can be used to set the date and time of the real time clock. Expert mode (C6.4.5 Expert Mode) The signal converter local menu is designed to to show only functions and parameters which are used by most users. For some applications additional functions (e.g. process noise damping, pressure suppression, ) are required which are only available if the expert mode (C6.4.5) is enabled. Within this mode the device cannot be set to SIL mode (only SIL capable device). If the expert mode is disabled all expert mode parameters are reset to their default values. 6.10 SIL configuration (only for SIL capable devices) Refer to "Safety manual" in case of functional safe device variant. 6.11 Testing of device installation (B3.0.0 Simulation) During installation of the device, the configuration should be tested using simulation functions of the signal converter (B3). The following simulation functions are available:

Function Description B3.2.0 Mass Flow Simulation of process variable mass flow. B3.3.0 Volume Flow Simulation of process variable volume flow. B3.4.0 Density Simulation of process variable density. B3.5.0 Temperature Simulation of process variable temperature. B3.6.0 Status Simulation of device status and process value status. This function requires a device status without failures. B3.7.0 I/O A to B3.10.0 I/O D Simulation of output signals for I/Os. Table 6-29: Available simulation functions INFORMATION!

Several simulation functions can run in parallel. Simulation functions only affect the respective process variable and do not affect derived process variables (e.g. simulation of mass flow does not affect volume flow). WARNING!

Once started simulation functions continue until they are stopped or the device performs a power cycle. The device status "Function Check" indicates running simulation functions. Use function "A2.2.0 Stop all Simulations" to stop all running simulation functions simultaneously. 102 www.krohne.com 01/2021 - 4002075808 - MA MFC400 ER2.1 R08 en MFC 400 OPERATION 6 6.12 Diagnostic information and status messages The signal converter continuously carries out various diagnostic functions during operation.
