Series 3730 Electropneumatic Positioner Type 3730-2 and Type 3730-3 with HART communication

Application Single-acting or double-acting positioner for attachment to pneumatic control valves. Self-calibrating, automatic adaptation to valve and actuator. Reference variable 4 to 20 mA Travels 3.6 to 200 mm Opening angles 24 to 100

The positioner ensures a predetermined assignment of the valve stem position (controlled variable x) to the electric input signal (reference variable w). It compares the control signal received from a controller to the travel or opening angle of the control valve and issues a corresponding output signal pressure (output variable y). Special features Simple attachment to common linear and rotary actuators with SAMSON direct attachment interface (Fig. 1), NAMUR rib (Fig. 2), valves with rod-type yokes acc. to IEC 60534-6-1 or rotary actuators acc. to VDI/VDE 3845 (Fig. 3) Any desired mounting position Simple one-knob, menu-driven operation LCD easy to read in any mounting position due to selectable reading direction Configurable with a PC over the SSP interface using the TROVIS-VIEW software Variable, automatic start-up with four different initialization modes Preset parameters only values deviating from the standard need to be adjusted Calibrated travel sensor without gears susceptible to wear "Sub" initialization mode (substitution) allows the positioner to be started up in case of emergency whilst the plant is running without the valve moving through the whole travel range All parameters saved in EEPROM (protection against power failure) Two-wire system with a small electrical load between 300 and 410 depending on the version (see Table 1) Adjustable output pressure limitation Tight-closing function can be activated Continuous monitoring of zero point Integrated temperature sensor and operating hours counter Two standard configurable position alarms Self-diagnostics; alarms as condensed state conforming to NAMUR Recommendation NE 107, issued over a fault alarm contact or optional analog position transmitter Integrated EXPERTplus diagnostics (see T 8388 EN), suitable for valves for throttling and on/off service with additional partial stroke test for valves in safety-related applications Certified according to IEC 61508/SIL

Additional options Inductive limit switch with proximity switch Analog position transmitter with two-wire transmitter Forced venting function with solenoid valve Binary input External position sensor (Fig. 4) Stainless steel housing Principle of operation The electropneumatic positioner is attached to pneumatic control valves. It is used to assign the valve stem position (controlled variable x) to the input signal (reference variable w). The input signal received from a control system is compared to the travel or opening angle of the control valve and an output signal pressure (output variable y) is produced. The positioner consists of an electric travel sensor system (2), an analog i/p converter with a downstream booster and the electronics unit with microcontroller (5). When a deviation occurs, the actuator is pressurized or vented. If required, the changes in the signal pressure can be slowed down by a volume restriction. The signal pressure to the actuator can be limited by software to 1.4, 2.4 or 3.7 bar. 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 case as well as to optimize the air capacity booster. The i/p module (6) is supplied with a constant upstream pressure by the pressure regulator (8) to make it independent of the supply air pressure.

Operation The positioner is operated with a user-friendly rotary pushbutton. The parameters are selected by turning the knob, pushing it activates the required settings. In the menu, all parameters are listed in one level, meaning there is no need to search through submenus. All parameters can be checked and changed on site. All values are displayed on the LCD. The reading direction of the LCD can be rotated by 180 at the push of a button. The closing direction of the control valve is indicated to the positioner by the slide switch "Air to open/Air to close". It assigns the CLOSED position of the control valve to the 0 % reading. The INIT key activates initialization, which is started according to (pre)set parameters (autotune). After initialization has been completed, the positioner immediately starts control operation. To configure the positioner with SAMSONs TROVIS-VIEW configuration software, the positioner is equipped with an additional digital interface to be connected to the RS-232 interface of a PC. Additionally, all parameters of the Type 3730-3 Positioner can be accessed using HART communication.

Positioner attachment The Type 3730 Electropneumatic Positioner can be attached directly to the Type 3277 Actuator over a connection block. In actuators with fail-safe action Actuator stem extends and Type 3277-5 Actuator (120 cm), the signal pressure is routed over an internal bore in the actuator yoke to the actuator. In actuators with fail-safe action Actuator stem retracts and in actuators with effective diaphragm areas of 240 cm or larger, the signal pressure is routed to the actuator over ready-made external piping. Dimensions in mm

Using a bracket, the positioner can also be attached according to IEC 60534-6-1 (NAMUR recommendation). The positioner can be mounted on any side of the control valve. A pair of universal brackets is used for the attachment to Type 3278 Rotary Actuators or other rotary actuators according to VDI/VDE 3845. The rotary motion of the actuator is transferred to the positioner over a coupling wheel.
