Design and principle of operation

3 Design and principle of oper-ation

Î RefertoFig. 1The electropneumatic positioner is mounted on pneumatic control valves and is used to assign the valve position (controlled variable x) to the control signal (set point w). The po-sitioner compares the electric control signal of a control system to the travel of the control valve and issues a signal pressure (output variable y)forthepneumaticactuator.

Asupplypressurebetween1.4to6 barisrequired. The electric input signal is a set pointbetween4to20 mA.The positioner is designed depending on which accessories are selected either for directattachmenttoSAMSONType 3277Actuators or for attachment to actuators accordingtoNAMUR(IEC 60534-6).The positioner consists of a travel sensor system proportional to resistance, an analog i/p converter with a downstream air capacity booster and the electronics with microcontroller.

Fig. 1: Functional diagram

EB 8384-0 EN 13


The position of the valve stem is transmitted as a linear travel motion over the pick-up le-ver to the travel sensor (2) and supplied to an analog PD controller (3). The PD control-ler compares this actual value to the DC con-trol signal coming from the control system, e.g.a4to20 mAsignal.In case of a system deviation, the activation of the i/p module (6) is changed so that the actuator of the control valve (1) is pressur-ized or vented accordingly over the down-stream booster (7). This causes the valve plug to move to the position determined by the set point.The supply air is supplied to the booster (7) and the pressure regulator (8). An intermedi-ateflowregulator(9)withfixedsettingsisused to purge the positioner and, at the same time, guarantees trouble-free operation of the booster. The output signal pressure supplied by the booster can be limited by enabling the DIP switch setting S5.The volume restriction (10) and the switch S6 are used to optimize the positioner by adapting it to the actuator size and chang-ing the gain factor.

Tight-closing function:After activating the tight-closing function (see section 7.4), the pneumatic actuator is com-pletelyfilledwithairorventedassoonasthe set point falls below or exceeds the corre-spondingdeactivatingpointof4.5 mAor19.5 mA.In the case of three-way valves, the function allows the plug move to the end position with full actuator thrust.

5.1 Mounting position

Risk of damage to the positioner due to in-correct mounting position. − Do not mount the positioner with the back of the device facing upward. − Do not seal or restrict the vent opening when the device is installed on site.

ÎObservemountingposition(seeFig. 3).

5.2 Lever and pin positionThe positioner is adapted to the actuator and to the rated travel by the lever on the back of the positioner and the pin inserted into the lever.The travel tables on page 17 show the maximum adjustment range at the position-er. The travel that can be implemented at the valve is additionally restricted by the selected fail-safe position and the required compres-sion of the actuator springs.The positioner is equipped with the M lever (pinposition35)asstandard(seeFig. 4).

The M lever is included in the scope of deliv-ery.S, L, XL levers are available as accessories (see Table 4 on page 16). The XXL lever is available on request.

If a pin position other than position 35 with the standard M lever is required or an L or XL lever size is required, proceed as follows (seeFig. 5):1. Fasten the follower pin (2) in the as-

signed lever hole (pin position as speci-fiedinthetraveltablesonpage 17).Only use the longer follower pin includ-ed in the mounting kit.

2. Place the lever (1) on the shaft of the po-sitioner and fasten it tight using the disk spring (1.2) and nut (1.1).

The following applies to all reversing am-plifiers:The signal pressure of the positioner is sup-pliedattheoutput1ofthereversingamplifi-er. An opposing pressure, which equals the required supply pressure (Z) when added to the pressure at output 1, is applied at output 2.The following relationship applies: output 1 + output 2 = Supply pressure (Z).Connect output 1 to the signal pressure con-nection on the actuator that causes the valve to open when the pressure rises.Connect output 2 to the signal pressure con-nection on the actuator that causes the valve to close when the pressure rises.

How the outputs are marked depends on the reversing amplifier used: − Type 3710: Output 1/2 = Y1/Y2 − 1079-1118 and 1079-1119: Output 1/2 = A1/A2

Note

NOTICE!

EB 8384-0 EN 45


FE: The air purging function is automatically provided.

Attachment according to IEC 60534-6 (NAMUR rib or attachment to rod-type yokes)

The positioner requires an additional port for the exhaust air that can be connected over piping. An adapter available as an accesso-ry is used for this purpose:

Threaded bushing (M20x1.5)

G ¼¼ NPT

0310-26190310-2550

The adapter uses one of the M20x1.5 con-nections in the housing which means only one cable gland can be installed.

Should other valve accessories be used which vent the actuator (e.g. solenoid valve, volume booster, quick exhaust valve), this ex-haust air must also be included in the purg-ing function. The connection over the adapt-er at the positioner must be protected with a check valve (e.g. check valve G ¼, order no. 8502-0597)mountedinthepiping.Other-wise the pressure in the positioner housing would rise above the ambient pressure and damage the positioner when the exhausting components respond suddenly.

5.10 Setting start-up parametersAfter the positioner has been mounted on the valve, all switches S1 to S10 must be set to OFF (see Operating controls of Type 3730-0Positioneronpage 53).

5.10.1 Fail-safe positionThe switch position of switch S1 depends on the fail-safe position of the valve: − AIR TO OPEN · Upon air supply failure,

the valve is completely closed by the actu-ator. As the signal pressure increases at the positioner output (38), the valve opens.

− AIR TO CLOSE · Upon air supply failure, the valve is completely opened by the ac-tuator. As the signal pressure increases at the positioner output, the valve closes.

To determine the switch position, read the associated switch position S1 = ON or OFF from the cover plate at the actuator symbols.The symbols are read properly when the symbol shows the actuator on top of the valve; symbols upside down do not apply.AIR TO OPEN: Pneumatic connections point to the right S1 = ON. Pneumatic connections point to the left S1 = OFF.AIR TO CLOSE: Pneumatic connections point to the right S1 = OFF. Pneumatic connections point to the left S1 = ON.AIR TO OPEN always applies for double-act-ing actuators. Proceed as described in sec-tion 5.11toconnectthereversingamplifier.

Decommissioning and removal

9.1 Emergency actionUpon failure of the air supply or electric sig-nal, the positioner vents the actuator, causing the valve to move to the fail-safe position de-termined by the actuator.

Emergency action in the event of valve or ac-tuator failure is described in the associated valve and actuator documentation.

Î The plant operator is responsible for emergency action to be taken in the plant.

10 Decommissioning and removal

Risk of fatal injury due to ineffective explo-sion protection.The explosion protection becomes ineffective when the positioner cover is opened.The following regulations apply to installa-tion in hazardous areas: EN 60079-14 (VDE 0165, Part 1).

The process is disturbed by interrupting closed-loop control.Do not mount or service the positioner while the process is running and only after isolat-ing the plant by closing the shut-off valves.

10.1 DecommissioningTo decommission the positioner before re-moving it, proceed as follows:1. Disconnect and lock the air supply and

signal pressure.2. Open the positioner cover and discon-

nect the wires for the control signal.

10.2 Removing the positioner1. Disconnect the wires for the control sig-

nal from the positioner.2. Disconnect the lines for supply air and

signal pressure (not required for direct attachment using a connection block).

3. To remove the positioner, loosen the three fastening screws on the positioner.

10.3 Disposal Î Observe local, national and internation-al refuse regulations.

Î Do not dispose of components, lubricants and hazardous substances together with your other household waste.
