can display up to eight fieldbus process variables, together with their units of measurement and tag information. The instrument is bus powered so no additional power supply is required. The instrument’s communication protocol is shown on a label inside the terminal cover. The ‘-F’ order number suffix also indicates the protocol but is not shown on the instrument identification label. There is an alternative version of the fieldbus display, order code BA684DF-P for use on Profibus PA networks. This instruction manual describes revision 3 BA684DF-F Foundation fieldbus displays which were introduced in January 2019. Revision 3 displays have been verified in the FieldComm Labs as compliant with ITK 6.3. Instruction manuals for the earlier revision 1 and 2 instruments may be downloaded from the superseded documentation section of the BEKA website. Most of the BA684DF-F display parameters are configured on-site via the fieldbus. Screen format selection and alarm configuration is performed using an internal menu and the instrument's front panel push buttons. Up to eight process variables can be displayed using the two Input Selector function blocks. The required Device Description files, which may be downloaded from either the FieldComm or the BEKA website, depend upon which BA684DF-F FOUNDATION™ fieldbus display revision is selected. Eleven selectable standard display screen formats enable one, two, three, four or eight process variables, some with bargraphs to be displayed on one screen. The BA684DF-F FOUNDATION™fieldbus display can be supplied with six optional alarm outputs that may be linked to any of the displayed fieldbus variables. These alarm outputs are locally activated from the fieldbus variables and are configured via the instrument menu and push buttons. They cannot be controlled via the fieldbus. Housed in a robust IP66 glass reinforced polyester (GRP) enclosure with a toughened glass window, the BA684DF-F is surface mounting, or may be pipe mounted using one of the accessory kits. 1.1 Documentation This instruction manual describes system design, conditioning and installation of the BA684DF-F FOUNDATION™fieldbus display. For detailed commissioning information please refer to the FOUNDATION™fieldbus Interface Guide that can be downloaded from the BEKA website www.beka.co.uk 1.2 Version 4.03 firmware Updated firmware was released in January 2019 which includes the following key features: 11 standard screens Multiple bargraph limits Individual input scaling Two 4-input Input Selector function blocks: Last variable parameter prevents display of unused inputs. Fieldbus compliance verified to ITK 6.3 Option added to remove status text from single variable screens. The instrument’s firmware version can be established using the ‘Unit Info’ function in the main configuration menu – see section 5.7.8 of this manual. 3

BA684DF-F FOUNDATION™ fieldbus display. When the optional alarms are not fitted, the instrument only requires a two-wire connection to the fieldbus. Parameters that cannot be configured via the fieldbus can be configured via the four front panel push buttons. Menus enable the required standard display screen format to be selected. The optional alarms are locally activated from the fieldbus variable and can only be configured and the setpoints adjusted using the BA684DF-F push buttons. The alarms cannot be configured or controlled via the fieldbus. Device Description files for the BA684DF-F FOUNDATION™ fieldbus display may be downloaded from either the Fieldbus Foundation or from the BEKA associates website. Fig 1 Simplified block diagram of BA684DF-F 2.1 Controls The user can scroll through the display screens by operating the ▼or ▲push buttons. The number of screens available depends upon how the BA684DF-F FOUNDATION™fieldbus display has been configured. If one fieldbus variable per screen has been configured, eight screens will be present; if four fieldbus variables per screen have been configured, only two screens will be available. Irrespective of the number of fieldbus variables assigned to the BA684DF-F, the instrument always has provision for displaying eight variables. Unassigned inputs are displayed as zero with a bad data warning i.e. light digits on a dark background. The Last Input parameter allows unused inputs to be skipped when scrolling through the instrument display screens, see section 5.7.5. If enabled, operating the P and ▲push buttons simultaneously activates the Quick Access Menu, allowing the user to adjust the display contrast without providing access to any of the other configuration parameters. Additional security may be provided by an optional access code. 4

The BA684DF-F FOUNDATION™fieldbus display may be connected to any fieldbus segment as shown in Fig 2, providing it can provide the additional 25mA required to operate the instrument. Fig 2 Fieldbus system 3.1 External switches For applications requiring operator inputs to be made by large industrial push buttons, terminals S1 to S7 allow up to six external switches to be connected to the Fieldbus Display. When external switches are connected, the front panel push buttons may be operated in parallel or disabled – see section 5.3.6. The BA684DF-F inputs S1 to S7 for external switches are not electrically isolated from the fieldbus terminals, switches and wiring must therefore be isolated from earth and all other electrical circuits. For reliable operation it is recommended that the cable connecting the Fieldbus Display to the external switches is less than 5m long. 3.2 Alarm outputs The BA684DF-F can be supplied with six alarm outputs that may be linked to any of the displayed variables. Each alarm output is a galvanically isolated single pole solid state switch output as shown in Fig 3. Fig 3 Equivalent circuit of each switch output The outputs are polarised and current will only flow in one direction. Odd numbered terminals should be connected to the positive side of the supply. Ron = 5 + 0.7V Roff = greater than 1M Note: Because of the series protection diode, some test meters may not detect a closed alarm output. WARNING These Alarm Outputs should not be used for critical safety applications such as an emergency shut down system. When the BA684DF-F FOUNDATION™fieldbus display is disconnected from the fieldbus, or the fieldbus is de-energised, all the alarm outputs will open irrespective of how they have been configured. 5

is housed in a robust IP66 glass reinforced polyester (GRP) enclosure incorporating an armoured glass window and stainless steel fittings. It is suitable for exterior mounting in most industrial environments, including off-shore and waste water treatment installations. Please consult BEKA associates if high vibration is anticipated. The BA684DF-F enclosure is surface mounting. Accessory kits described in sections 7.2 of this manual enable the instrument to be mounted onto a vertical or horizontal pipe. The field terminals and the two mounting holes are located in a separate compartment with a sealed cover allowing the instrument to be installed without exposing the display assembly. The BA684DF-F earth terminal is connected to the carbon loaded GRP case. If the case is not bolted to a post or structure connected to the plant’s potential equalising conductor, the instrument’s earth terminal should be connected to the potential equalising conductor. The BA684DF-F enclosure is supplied with a bonding plate to ensure electrical continuity between the three conduit / cable entries. 4.2 Installation Procedure Fig 4 illustrates the instrument installation procedure. a. Remove the instrument terminal cover by unscrewing the two captive 'A' screws. b. Mount the instrument on a flat surface and secure with two M6 screws through the 'B' holes. Alternatively use one of the mounting kits described in section 7.2 c. Remove the temporary hole plug and install an appropriate IP rated cable gland or conduit fitting. If more than one entry is required, one or both of the IP66 stopping plugs may be replaced with an appropriate IP rated cable gland or conduit fitting. d. Connect the field wiring to the terminals as shown in Fig 5. e. Replace the instrument terminal cover and evenly tighten the two 'A' screws. Fig 4 BA684DF-F installation procedure 4.3 EMC The BA684DF-F complies with the requirements of the European EMC Directive 2014/30/EU. For specified immunity, all wiring should be in screened twisted pairs with the screens connected to the plant’s potential equalising conductor. 6

5.1 Display transducer block In addition to loading the BA684DF-F FOUNDATION™ fieldbus display Device Description files onto the system host, the eight inputs require individual configuration. Each of the four inputs of the two Display Transducer Blocks has the following fieldbus configurable parameters: Bargraph_Min Defines bargraph lower limit Bargraph_Max Defines bargraph higher limit Display_format Defines the position of the displayed decimal point. Six options are available: Auto Max resolution with selected display format. 4 DP 4 digits on right of decimal point 3 DP 3 digits on right of decimal point 2 DP 2 digits on right of decimal point 1 DP 1 digit on right of decimal point 0 DP No decimal point Zero_offset Adds a positive or negative offset to the fieldbus variable before it is displayed. Gain_factor Multiplies the fieldbus variable by a factor before it is displayed. Display = (Gain factor x fieldbus variable) + Offset Descriptor Displayed fieldbus variable identification. Up to 16 characters can be accepted but the number displayed varies depending upon the display screen selected. Units Displayed units of measurement. Up to 8 characters can be accepted, but the number displayed varies depending upon the display screen selected. IN_value Fieldbus value to be displayed IN_value_status Indicates validity of displayed fieldbus value. 5.2 Screen selection and alarm configuration Screen selection and, if fitted, alarm configuration is performed via the four front panel push buttons. All the display and alarm configuration functions are contained in an easy to use menu that is shown in Fig 7. Where necessary the sub-menus contain on-screen prompts to guide the user through each adjustment. When navigating through the configuration menu, the push button(s) should be held until the required screen is displayed. 5.3 Default configuration Unless otherwise requested at the time of ordering, BA684DF-F FOUNDATION™fieldbus displays will be supplied configured as follows: Keys Both Display brightness 100% Display contrast 50% Quick access menu On Quick access menu code 0000 Configuration menu access code. 0000 Screen Single variable Number Format Auto All alarms Disabled Alarm activation Good data only Alarm outputs N/C Bargraph Low 0 High 100 Input scaling Zero offset 0 Gain factor 1 Status text On Last input 8 Revision Revision 3 (2 x IS function blocks) 8

menu. Throughout this manual push buttons are shown in italics e.g. P E ▼▲and legends displayed by the instrument are shown within inverted commas e.g. 'Enter Access Code'. Operating the P and E push buttons simultaneously accesses the display configuration menu. If the BA684DF-F is not protected by an access code the main menu will be displayed. If an access code other than the default code 0000 has already been entered, the BA684DF-F will request that the access code be entered. Using the ▼or ▲button set the first digit of the code which will be flashing. Pressing P will transfer control to the next digit, which should be adjusted in the same way. When all four digits have been set, pressing the E button will enter the access code. If the code is correct the main menu will be displayed, if the code is incorrect ‘Invalid Code’ will be displayed. When entering an access code, timeout will occur and the instrument will automatically return to the operating mode ten seconds after a push button was last operated. In all other menus, timeout occurs after sixty seconds. The structure of the display configuration menu is shown in Fig 7. Navigation is achieved by highlighting the required function using the ▼and ▲buttons and then operating the P button to display the selected function sub-menu, from which a further selection or adjustment may be made. Operating the E button moves the display back one level. A flashing highlight indicates that an option or alphanumeric character may be selected using the ▼and ▲buttons and entered using the E button. If only one entry or adjustment can be made in a sub-menu, the display will automatically move up one menu level when the adjustment is entered. If more than one adjustment can be made in a sub- menu, the highlight may be moved to the second variable using the ▼or ▲button after the first setting has been entered. Operating the P button allows the second variable to be adjusted. When multiple numeric or alpha characters are adjusted e.g. an alarm setpoint or a tag legend, the adjustment is made one digit at a time using the ▼ and ▲buttons. After the first flashing digit has been set as required, the flashing highlight can be moved to the next digit by operating the P button. When all digits have been set, operating the E button will enter the setting. Following completion of the instrument configuration, the E button should be operated to step the display back to the main menu. One more operation of the E button will then return the BA684DF-F to the operating mode. 9

The BA684DF-F FOUNDATION™fieldbus display can display up to eight fieldbus variables that are identified as IN_1 to IN_8. The fieldbus variable that each one represents is determined by the BA684DF-F configuration at the fieldbus system host - see the FOUNDATION fieldbus™Interface Guide. This sub-menu allows one of eleven standard display formats containing one, two, three, four or eight fieldbus variables some with bargraphs as shown below. . One variable Two variables Four variables Eight variables One variable + horizontal bargraph Two variables + horizontal bargraphs One variable + vertical bargraph Two variables + vertical bargraphs Three variables + vertical bargraphs Four variables + vertical bargraphs Eight variables + horizontal bargraphs 10

Note: Alarm menus are only included when the BA684DF-F is fitted with optional alarm outputs. Outputs are locally activated from the fieldbus variables and are configured via the instrument menus and push buttons. They cannot be controlled via the fieldbus. Each of the six alarms may be linked to any one of the eight fieldbus variables displayed by the BA684DF-F. Each alarm output can be conditioned to function as a high or a low alarm, or as a combined high and low alarm. The output can be conditioned as normally open ‘N/O’, or normally closed ‘N/C’ in the non-alarm condition. Irrespective of settings alarm outputs will be open when the instrument is not powered from the fieldbus. When an alarm is activated, the associated fieldbus variable display flashes, i.e. alternates between dark figures on a light background and light figures on a dark background. There are eight alarm-conditioning sub-menus. 5.6.1 Alarm summary Shows to which fieldbus variable each alarm is linked and how each alarm has been conditioned i.e. high, low, or combined high & low alarm with normally open or closed output. No adjustments can be made in this sub-menu. 5.6.2 Alarm activation Fieldbus variables that have not been validated are displayed with dark characters on a light background, and some screen formats also contain a status indication. This sub-menu allows the alarm outputs to be conditioned so that they only operate with validated fieldbus data, or to operate irrespective of data validity. 5.6.3 Alarm output There is a separate sub-menu for each of the six alarm outputs; these link the alarm to one of the displayed fieldbus variables and define the alarm function and the setpoints. To link the alarm to a displayed variable, position the cursor over the ‘IN_n’ field, press P and using the ▼or ▲button select the required input source. Enter the selection by pressing the E button. Each alarm output can be N/O or N/C in the non- alarm condition. To change the setting, position the highlight over the ‘N/O’ or ‘N/C’ field, press P and use the ▼or ▲button to toggle the setting. Enter the selection by pressing the E button. Each alarm has three functions that can be independently enabled to condition the output as a low or high alarm, or as a combined low and high alarm, either with or without hysteresis. The required functions can be individually enabled by positioning the highlight over the Enb/Dis (Enabled/Disabled) column, pressing P and toggling the function to the required state, then entering the selection by pressing the E button. Alarm setpoints are entered digit by digit. Place the highlight over the setpoint to be adjusted and press P; the flashing digit to be adjusted may then be selected by again pressing P. When all the digits have been adjusted, operating the E button enters the value and moves the menu up one level. The function of all alarms may be reviewed from the alarm summary menu - see 5.6.1. 11

5.7.1 Settings The backlight brilliance and display contrast are adjustable from this sub-menu. 5.7.2 Quick Access This sub-menu enables the Quick Access Menu which is described in sections 2.1 & 5.8. When enabled, an operator can adjust the display contrast and backlight brilliance without having access to any other conditioning menus. 5.7.3 Access Code Defines a four digit alphanumeric code that must be entered to gain access to the Quick Access Menu. Alpha characters are case sensitive. Default code 0000 allows direct access without a code. 5.7.4 Status Text The two single variable screens 1 and 4 will show the status of the FOUNDATION™fieldbus variable as ‘Good’ or ‘Bad’ if the Status Text function is activated. 5.7.5 Last Input This function allows the maximum number of FOUNDATION™fieldbus variables to be defined so that unused inputs are skipped when the display is scrolled in the operating mode. 5.7,6 Keys The function of the front panel push buttons may be transferred to the six optional external push buttons, with or without disabling the BA684DF-F front panel push buttons. The table below shows the function of the BA684DF-F front panel and the external push buttons for each of the four options that may be selected in the Keys sub-menu. For applications where the instrument is only displaying 1, 2, 3, 4 or 8 variables on a single screen, it is recommended that external buttons are selected but not fitted. This will disable the instrument front panel buttons, but still provide access to the configuration menu, which may be protected by a security code. 5.7.7 Code Defines the four digit alphanumeric code that must be entered to gain access to the instrument configuration menus. Alpha characters are case sensitive. Default code 0000 allows direct access without a code. 5.7.8 Unit Info Displays the instrument model number and the firmware version. 5.7.9 Defaults This function enables the display and interface board factory defaults to be restored. 5.7.10 Display Defaults This function restores the display defaults defined in section 5.1. CAUTION Existing settings cannot be recovered after this function has been used. 5.7.11 Interface Board Defaults This function restores the Fieldbus Interface Board factory defaults. CAUTION Do not use this function when the BA684DF-F is connected to an operational fieldbus, as communication will be terminated. 12

The Quick Access Menu allows an operator to adjust the backlight brilliance and the display contrast without having access to the other configuration parameters. The quick access menu is accessed by operating the P and ▲push buttons simultaneously. If the Quick Access Menu is not protected by an access code the contrast and brilliance controls will be displayed immediately. If an access code other than the default code 0000 has already been entered, the BA684DF-F will request that the access code be entered. The display backlight brilliance is adjusted using the ▼and ▲push buttons. Operating the P push button will transfer control to the display contrast adjustment. When both are set as required, operating the E button will store both settings and return the instrument to the operating mode. 13
