Intended use
TheSAMSONType3730-0Positionerismountedonpneumaticcontrolvalvesandisusedto
assign the valve position to the control signal. The device is designed to operate under exact-
lydenedconditions(e.g.operatingpressure,temperature).Therefore,operatorsmusten-
sure that the positioner is only used in applications where the operating conditions corre-
spond to the technical data. In case operators intend to use the positioner in other applica-
tionsorconditionsthanspecied,contactSAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.

Qualications of operating personnel
The positioner is to be mounted, started up or operated only by trained and experienced
personnel familiar with the product. According to these mounting and operating instructions,
trained personnel refers to individuals who are able to judge the work they are assigned to
and recognize possible hazards due to their specialized training, their knowledge and expe-
rience as well as their knowledge of the applicable standards.
Explosion-protected versions of this device are to be operated only by personnel who has un-
dergone special training or instructions or who is authorized to work on explosion-protected
devices in hazardous areas.

Safety instructions and measures
Personal protective equipment
No personal protective equipment is required for the direct handling of the positioner. Work
on the control valve may be necessary when mounting or removing the device.
ÎObservetherequirementsforpersonalprotectiveequipmentspeciedinthevalvedocu-
mentation.
ÎCheck with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions,conversionsorothermodicationsoftheproductarenotauthorizedbySAMSON.
They are performed at the user's own risk and may lead to safety hazards, for example. Fur-
thermore, the product may no longer meet the requirements for its intended use.
Safety features
Upon failure of the air supply or electric signal, the positioner vents the actuator, causing the
valve to move to the fail-safe position determined by the actuator.
Warning against residual hazards
Thepositionerhasdirectinuenceonthecontrolvalve.Anyhazardsthatcouldbecausedin
the valve by the process medium, the signal pressure or by moving parts are to be prevented
by taking appropriate precautions. They must observe all hazard statements, warning and
caution notes in these mounting and operating instructions, especially for installation, start-
up and service work.
If inadmissible motions or forces are produced in the pneumatic actuator as a result of the
supply pressure level, it must be restricted using a suitable supply pressure reducing station.

ÎInstallation, operation or maintenance of the positioner must only performed by per-
sonnel who has undergone special training or instructions or who is authorized to
work on explosion-protected devices in hazardous areas.
1.2 Notes on possible property damage
NOTICE
!
Risk of damage to the positioner due to incorrect mounting position.
ÎDo not mount the positioner with the back of the device facing upward.
Risk of malfunction due to incorrect sequence during start-up.
The positioner can only work properly if the mounting and start-up are performed in the
prescribed sequence.
ÎPerformmountingandstart-upasdescribedinsection5inpage26.
An incorrect electrical power supply will damage the positioner.
A current source must be used to provide the electrical power for the positioner.
ÎOnly use a current source and never a voltage source.

Safety instructions and measures
Incorrect assignment of the terminals will damage the positioner and will lead to mal-
function.
For the positioner to function properly, the prescribed terminal assignment must be ob-
served.
ÎConnect the electrical wiring to the positioner according to the prescribed terminal
assignment.
Risk of positioner damage due to incorrect grounding of the electric welding
equipment.
ÎDo not ground electric welding equipment near to the positioner.

Design and principle of operation
3 Design and principle of oper-
ation
ÎRefertoFig.1
The 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
variabley)forthepneumaticactuator.
Asupplypressurebetween1.4to6baris
required. The electric input signal is a set
pointbetween4to20mA.
The positioner is designed depending on
which accessories are selected either for
directattachmenttoSAMSONType3277
Actuators or for attachment to actuators
accordingtoNAMUR(IEC60534-6).
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.

Design and principle of operation
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.a4to20mAsignal.
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-
ateowregulator(9)withxedsettingsis
used 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-
pletelylledwithairorventedassoonas
the set point falls below or exceeds the corre-
spondingdeactivatingpointof4.5mAor
19.5mA.
In the case of three-way valves, the function
allows the plug move to the end position
with full actuator thrust.
