General
The Type3730-3 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 IEC61508, 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 IEC61511 and the re-
quired hardware fault tolerance in safety-instrumented systems up to SIL2 (single device/
HFT=0) and SIL3 (redundant conguration/HFT=1).
The individual safety functions of the positioner are to be regarded as TypeA elements in ac-
cordance with IEC61508-2.
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
Type3730-3 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 contactSJ2-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 20mA 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 (0mA) 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 24VDC voltage signal. Fail-safe action is trig-
gered when no signal (0mA) 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 contactSJ2-SN (NAMUR NC contact) indicates the adjusted end posi-
tion in a safety-instrumented system at terminals 41/42. See u EB8384-3 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 conguration
A change to the conguration cannot affect the safety function nor cause it to be deactivated.
