Design and principle of operation 3 variable y) is produced for the pneumatic actuator. Design and principle of operation The electropneumatic Ex d positioner is mounted on pneumatic control valves. It is used to assign the valve stem position (controlled variable x) to the control signal (reference variable w).
Design and principle of operation software or on site at the positioner. A constant air stream to the atmosphere is created by the flow regulator (9) with a fixed set point. The air stream is used to purge the inside of the housing as well as to optimize the air capacity booster (7). The i/p converter (6) is supplied with a constant upstream pressure by the pressure regulator (8) to make it independent of the supply pressure. All parts are enclosed in an Ex d housing.
Design and principle of operation Binary input 3.2 The positioner has an optional binary input. The following actions can be performed over the binary input: The positioner is equipped with an interface for HART® protocol (Highway Addressable Remote Transducer) for communication purposes. Data are transmitted in a superimposed frequency (FSK = Frequency Shift Keying) on the existing signal loop for the 4 to 20 mA reference variable.

Do not touch the actuator stem or obstruct it to avoid risk of injury to hands or fingers. 5.
Connections 5.1.1 Signal pressure gauges If there are no specifications, calculate as follows: To monitor the supply air (Supply) and signal pressure (Output), we recommend that pressure gauges be attached (see accessories in Tables 1 to 5). Required supply pressure = Upper bench range value + 1 bar 5.1.2 Supply pressure The required supply pressure (of supply air) depends on the bench range and the actuator's operating direction (fail-safe action).
Connections 5.2 Electrical connections DANGER! Risk of electric shock and/or the formation of an explosive atmosphere! 4 For electrical installation, you are required to observe the relevant 4 electrotechnical regulations and the accident prevention regulations that apply in the country of use. The following standard applies for assembly and installation in hazardous areas: EN 60079-14 (VDE 0165 Part 1) Explosive atmospheres - Electrical installations design, selection and erection.
Connections Connection to conform with the type of protection Ex i (EN 60079-11): For connection to a certified, external instrinsically safe circuit, the terminal compartment of the positioner may be opened within the hazardous area. Only the terminal compartment is to be opened within the hazardous area to connect it to a certified instrinsically safe circuit. Positioners that are connected to non-intrinsically safe circuits are no longer permitted to be used as instrinsically safe equipment.
Connections Cable entry mum (reverse polarity protection, see Technical data). NOTICE The demanded degree of protection might not be met because the terminal compartment is not sealed tightly. Only operate the positioner with sealed cable entries and with the lid screwed on properly.

Connections Note: Communication errors may occur when the process controller/control station output is not HART-compatible. For adaptation, the Z box (order no. 1170-2374) can be installed between output and communication interface. At the Z box a voltage of 330 mV is released (16.5 Ω at 20 mA). Alternatively, a 250-Ω resistor can be connected in series and a 22-µF capacitor can be connected in parallel to the analog output. Note that in this case, the controller output load will increase.

The reading on the display can be turned by 180° to adapt it to how the positioner is attached.
Start-up – Settings 7.3 Checking the operating range of the positioner A horizontal lever (mid-position) is equal to 0°. To check the mechanical attachment, the valve should be moved through the operating range of the positioner in the manual mode using the manual reference variable w. Select manual operating mode (MAN) : Mode Default: MAN Turn → Code 0 Press , Code 0 blinks. Turn → MAN Press mode.

Start-up – Settings NOTICE If the positioner is mounted onto another actuator or its mounting position is changed, reset the positioner to its default settings before re-initializing it. Refer to section 7.7. During initialization the positioner adapts itself optimally to the friction conditions and the signal pressure requirements of the control valve.
Start-up – Settings 7.5.1 Initialization based on MAX maximum range Start initialization: The positioner determines travel/angle of rotation of the closing member from the CLOSED position to the opposite side and adopts this travel/angle of rotation as the operating range from 0 to 100 %.

Start-up – Settings 7.5.4 SUB substitute calibration A complete initialization procedure takes several minutes and requires the valve to move through its entire travel range several times. This initialization mode, however, is an emergency mode, in which the control parameters are estimated and not determined by an initialization procedure. As a result, a high level of accuracy cannot be expected. You should always select a different initialization mode if the plant allows it.
Start-up – Settings Select initialization mode: Initialization mode Default: MAX → Code 6 Turn Press Change pressure limit and control parameters: Note: Do not change the pressure limit (Code 16). Only change the control parameters KP (Code 17) and TV (Code 18) if the settings of the replaced positioner are known. → SUB Turn Press mode.

Turn → Blocking position, e.g. 5 mm (read off at travel indicator scale of the blocked valve or measure with a ruler).
Start-up – Settings Press The positioner changes to automatic mode (AUTO). The current valve position is indicated in % on the display. Note: If the positioner shows a tendency to hunt in automatic operating mode, the parameters KP and TV must be slightly corrected. Proceed as follows: – Set TV (Code 18) to 4. – Reduce KP (Code 17) until the positioner shows a stable behavior. Zero point correction Finally, if process operations allow it, the zero point must be calibrated as described in section 7.6. 7.
Start-up – Settings Press display: MAN, Code 0 blinks. Turn → Init Press The setting of the fail-safe position AtO or AtC appears. Keep pressed down for 6 seconds. Zero calibration is started, the positioner moves the control valve to the CLOSED position and recalibrates the internal electrical zero point. 7.7 Reset to default values This function resets all start-up parameters and diagnosis data to their default values (see code list in section 11).
Operation 8 Operation WARNING! The actuator stem moves while the positioner is being operated. Do not touch the actuator stem or obstruct it to avoid risk of injury to hands or fingers. 8.1 Enabling and selecting parameters All codes with their meanings and default settings are listed in the code list in section 11 on page 65 onwards. The codes which are marked with an asterisk (*) must be enabled with Code 3 before the associated parameters can be configured as described below.
Operation 8.2 Adjust the manual reference variable Operating modes 8.2.1 Automatic (AUTO) and manual (MAN) modes After initialization has been completed successfully, the positioner is in automatic mode (AUTO). Automatic mode % Switching to manual mode (MAN) % Turn → Code 1 Press , Code 1 blinks. Turn until sufficient pressure has been built up in the positioner and the control valve moves to the required position. Note: If no settings are entered within approx.
Operation 8.2.2 Fail-safe position (SAFE) If you want to move the valve to fail-safe position determined during start-up (see section 7.4), proceed as follows: → Code 0 Turn Press , display: current operating mode (AUtO or MAN), Code 0 blinks. → SAFE Turn Press , display: S The valve moves to the fail-safe position. If the positioner is initialized, the current valve position is indicated on the display in %. Exit the fail-safe position Turn → Code 0 Press , Code 0 blinks.
Operation 4 Out of specification Fault alarm output The positioner is operated outside specified operating conditions. Note: If an event is assigned to the “No message” status, this event does not have any effect on the condensed state. The condensed state is represented by the following icons on the positioner display: Positioner display Condensed state Maintenance alarm 4 The “Function check” condensed state can also switch the fault alarm contact in Code 32.
Maintenance 9 Maintenance The positioner does not require any maintenance. There are filters with a 100 µm mesh size in the pneumatic connections for supply and output which can be removed and cleaned, if required. The maintenance instructions of any upstream supply air pressure reducing stations must be observed.
