General
The Type3730-3 Electropneumatic Positioner is a single-acting, venting positioner with
HART®communication for attachment to pneumatic rotary and linear actuators with
spring-return mechanism. The positioner is used to position control valves.
Use in safety-instrumented systems
Observing the requirements of IEC61508, the systematic capability of the pilot valve for
emergency venting as a component in safety-instrumented systems is given.
Use of the positioner is possible on observing the requirements of IEC61511 and the re-
quired hardware fault tolerance in safety-instrumented systems up to SIL2 (single device/
HFT=0) and SIL3 (redundant conguration/HFT=1).
The individual safety functions of the positioner are to be regarded as TypeA elements in ac-
cordance with IEC61508-2.
The architecture and the interval between proof tests must be changed accordingly for a
higher safety integrity level.
Versions and ordering data
Apart from the low-temperature version with metal cable gland, all versions of the
Type3730-3 Positioner are suitable for use in safety-instrumented systems. However, the op-
tional equipment affects the safety-related behavior of the positioner. These options are the
inductive limit contactSJ2-SN and the solenoid valve.
The article code written on the nameplate provides details on the optional equipment of the
positioner:

Safety-related functions
3 Safety-related functions
1. Emergency venting over the i/p converter (Fig.1 path )
In automatic operation, the PD controller (3) compares the actual value to the DC control
signal from 4 to 20mA coming from the microcontroller. In case of a system deviation,
the activation of the i/p converter is changed so that the actuator (1) is either vented or
lled with air. Fail-safe action is triggered when no signal (0mA) is applied to terminals
11/12 and, as a result, to the i/p converter.
2. Emergency venting over the optional solenoid valve (Fig.1 path )
The solenoid valve (12) is energized by a 24VDC voltage signal. Fail-safe action is trig-
gered when no signal (0mA) is applied to terminals 81/82. This causes the solenoid
valve (12) to vent the output of the i/p converter to the atmosphere. The actuator is vent-
ed as well.
3. Safety-related end position monitoring over the optional inductive limit contact
(Fig.1 path )
The inductive limit contactSJ2-SN (NAMUR NC contact) indicates the adjusted end posi-
tion in a safety-instrumented system at terminals 41/42. See u EB8384-3 for adjusting
the limit contacts.
Fail-safe action
Fail-safe action is triggered by the i/p converter or solenoid valve and upon supply air fail-
ure. The positioner fully discharges its pneumatic output to the atmosphere, causing the
mounted actuator to be vented. As a result, the valve moves to the fail-safe position. The fail-
safe position depends on how the springs are arranged in the pneumatic actuator (air-to-
close or air-to-open).
When the air supply fails and the optional solenoid valve is de-energized, all positioner
functions, except open/closed loop control, remain active (including diagnostics, HART®
communication as well as position and status feedback).
The pneumatic output of the positioner can also be vented to the atmosphere over the
software, e.g. by entering a suitable set point. This procedure is not a safety-instrumented
function.
Protection against unauthorized changes to the conguration
A change to the conguration cannot affect the safety function nor cause it to be deactivated.

Required conditions
5 Required conditions
Risk of malfunction due to incorrect selection or wrong installation and operating conditions.
Only use control valves in safety-instrumented systems after the necessary conditions in the
plant have been fullled. The same applies to the mounted positioner.
Selection
ÎThe required transit times of the control valve are kept.
The transit times to be implemented are determined by the process engineering require-
ments.
The minimum OPEN and CLOSE transit times can be read in Codes 40 and 41 after the
positioner has been initialized.
ÎThe positioner is suitable for the prevailing ambient temperature.
Versions Temperature range
All –20 to +80 °C
With metal cable gland –45 to +80 °C
The limits in the test certicates additionally apply to explosion-protected versions.
ÎThe temperature limits are observed.
Mechanical and pneumatic installation
ÎThe positioner is mounted properly as described in the mounting and operating instruc-
tions and connected to the air supply.
Error codes 50 to 58 indicate incorrect attachment. For safety-instrumented systems, we
recommend assigning the 'Maintenance alarm' status to these errors to quickly recognize
them when they occur (indicated by on the display).
ÎThe maximum supply pressure does not exceed 7bar.
ÎThe pneumatic air supply meets the instrument air specications.

We recommend installing a supply pressure regulator/lter upstream of the positioner.
For example, the SAMSON Type4708 Supply Pressure Regulator with 5µm lter car-
tridge can be used.
ÎThe supply air line has a minimum inside diameter of 4mm.
Select the cross section and length of the line to ensure that the supply pressure at the po-
sitioner on lling the actuator with air does not fall below the minimum limit.
ÎThe positioner is mounted as prescribed.
ÎThe vent opening at the back of the positioner remains open when the positioner is in-
stalled on site.
Electrical installation
ÎThe positioner is connected to the electric power supply properly as described in the
mounting and operating instructions.
ÎOnly cables whose outside diameters are suitable for the cable glands are used.
ÎThe electrical cables in Ex i circuits comply with the data that planning was based on.
ÎThe cable glands and cover screws are fastened tightly to ensure that the degree of pro-
tection is met.
ÎThe installation requirements for the applicable explosion protection measures are ob-
served.
ÎThe special conditions specied in the explosion protection certicates are observed.
Operation
ÎWhen the optional inductive limit contact is used, Code 38 is set to YES.
ÎThe inductive limit contact is adjusted mechanically to meet the specications.

Proof testing
6 Proof testing
The proof test interval and the extent of testing lie within the operator's responsibility. The
operator must draw up a test plan, in which the proof tests and the interval between them
are specied. We recommend summarizing the requirements of the proof test in a check-
list.
Risk of dangerous failure due to malfunction in the event of emergency (actuator is not vented
or the valve does not move to the fail-safe position).
Only use devices in safety-instrumented systems that have passed the proof test according to
the test plan drawn up by the operator.
Regularly check the safety-instrumented function of the entire SIS loop. The test intervals are
determined, for example on calculating each single SIS loop in a plant (PFDavg).
Function testing
Regularly check the safety function according to the test plan drawn up by the operator.
Record any faults in the positioner and inform SAMSON of them in writing.
−Emergency venting by applying a 0mA signal to terminals 11/12 (control signal):
1. Apply supply air within the permissible range (max. 7bar) to the positioner which
allows the valve to move to the maximum travel/angle of rotation.
2. Apply an electric input signal ≥3.6mA to the positioner (terminals 11/12).
3. Switch the positioner to automatic mode (if it has not already been done).
4. Apply the input signal (terminals 11/12) over a local current source or over the con-
trol system in such a way that the valve moves to 50% of its travel/opening angle.
The travel in automatic mode can be read at the positioner in Code 0.
5. Set the electric input signal to 0mA or disconnect it.
This must cause the valve to move to its fail-safe position (terminals 11/12).

Repairs
Visual inspection to avoid systematic failure
To avoid systematic failure, inspect the positioner regularly. The frequency and the scope of
the inspection lie within the operator's responsibility. Take application-specic inuences into
account, such as:
−Dirt blocking the pneumatic connections
−Corrosion (destruction primarily of metals due to chemical and physical processes)
−Material fatigue
−Aging (damage caused to organic materials, e.g. plastics or elastomer, by exposure to
light and heat)
−Chemical attack (organic materials, e.g. plastics or elastomer, which swell, leach out or
decompose due to exposure to chemicals)
Risk of malfunction due to the use of unauthorized parts.
Only use original parts to replace worn parts.
7 Repairs
Only perform the work on the positioner described in uEB 8384-3.
Fail-safe action impaired due to incorrect repair.
Service and repair work must only be performed by trained staff.
