Page 5: Scope
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. -

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 filled with air. - Page 9 Safety-related functions Serial Serial Interface Interface 24 V DC Control valve 13* Analog position transmitter Travel sensor Software limit contact, alarm 1/2 PD controller Fault alarm output, alarm 3 A/D converter Display Microcontroller 17* Actuation of solenoid valve i/p converter 18* Electrical insulation Air capacity booster D/A converter...

Page 11: Required Conditions
Required conditions 5 Required conditions WARNING 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 fulfilled. The same applies to the mounted positioner. Selection Î... - Page 12 We recommend installing a supply pressure regulator/filter upstream of the positioner. For example, the SAMSON Type 4708 Supply Pressure Regulator with 5 µm filter car- tridge can be used. Î The supply air line has a minimum inside diameter of 4 mm.

Page 13: Proof Testing
Regularly check the safety function according to the test plan drawn up by the operator. Note 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. - Page 14 Proof testing 6. Check whether the actuator is fully vented within the demanded time. Connect a pressure gauge to check that the actuator has completely vented. − Emergency venting by applying a 0 V signal to terminals 81/82 (solenoid valve): 1. Apply supply air within the permissible range (max. 7 bar) to the positioner which al- lows the valve to move to the maximum travel/angle of rotation.
