Scope1 Scope
1.1 General
The Type 3963 Solenoid Valve converts binary voltage signals into pneumatic control signals.
It is used to control pneumatic rotary and linear actuators with spring-return mechanism.

1.2 Use in safety-instrumented systems
Observing the requirements of IEC 61508, the systematic capability of the solenoid valve for
emergency venting as a component in safety-instrumented systems is given.
Use of the solenoid valve is possible on observing the requirements of IEC 61511 and the required hardware fault tolerance in safety-instrumented systems up to SIL 2 (single device/
HFT = 0) and SIL 3 (redundant configuration/HFT = 1).
The individual safety functions of the solenoid valve are to be regarded as Type A elements inaccordance with IEC 61508-2.

1.3 Versions and ordering data
All versions of the solenoid valve marked with the prefix SIL are suitable for use in safetyinstrumented systems. The article code written on the nameplate (see 6 ff.) provides
details on the optional equipment of the solenoid valve.

Safety-related functions

4 Safety-related functions
4.1 Emergency venting
The solenoid valve is energized by a binary voltage signal. Fail-safe action is triggered whenno voltage signal (0 V AC/DC) is applied to terminals +81 and –82. The solenoid valve
vents to the atmosphere and the actuator is vented as well (see Fig. 1).

4.2 Fail-safe action
Fail-safe action is triggered by the solenoid valve and upon supply air failure.
The solenoid valve fully discharges its pneumatic output to the atmosphere, causing themounted actuator to be vented. As a result, the valve moves to the fail-safe position. The failsafe position depends on how the springs are arranged in the pneumatic actuator (air-toclose or air-to-open).

5 Mounting, connection and start-up
Refer to Mounting and Operating Instructions u EB 3963 on how to mount the solenoid
valve, perform the electric and pneumatic connections as well as start up the solenoid valve.
Only use original mounting parts and accessories.

Required conditions

6 Required conditions! WARNING
Risk of malfunction due to incorrect selection or wrong installation and operating conditions.
Î Only use control valves in safety-instrumented systems if the necessary conditions in theplant are fulfilled. This also applies to the mounted solenoid valve.

6.1 Selection
Î The required transit times of the control valve are observed.
The transit times to be implemented are determined by the process engineering requirements.

Required conditions

Tip
We recommend installing a supply pressure regulator/filter upstream of the device.
For example, Type 3999-009x Service Unit or Type 3999-0096 Filter Regulator can beused.
Î The minimum required cross section of the connecting lines is observed: 4 mm inside diameter for the external pilot supply (9) and 4 mm inside diameter for the internal pilot
supply (4) for KVS 0.16/0.32 and 6 mm inside diameter for the internal pilot supply (4)for KVS 2.0/4.3.
See "Sizing of the connecting line" in the mounting and operating instructions
u EB 3963.
Î Select the cross section and length of the line to ensure that the supply pressure at the device on supplying air does not fall below the minimum limit of 1.4 bar.
Î The solenoid valve is mounted as prescribed.
Î The exhaust opening at the solenoid valve remains open when the solenoid valve is installed on site.

6.3 Electrical installation
Î The solenoid valve is mounted properly as described in the mounting and operating instructions and connected to the electric power supply.
Î Only cables whose outside diameters are suitable for the cable glands are used.
Î The electrical cables in Ex i circuits comply with the data that planning was based on.
Î The cable glands and enclosure cover screws are fastened tightly to ensure that thedegree of protection is met.
Î The installation requirements for the applicable explosion protection measures are observed.
Î The special conditions specified in the explosion protection certificates are observed.

Proof testing

7 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 specified. We recommend summarizing the requirements of the proof test in a checklist.
! WARNING
Risk of dangerous failure due to malfunction in the event of emergency (actuator is notvented or the valve does not move to the fail-safe position).
Î 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).

7.1 Visual inspection to avoid systematic failure
To avoid systematic failure, inspect the solenoid valve regularly. The frequency and the scopeof the inspection lie within the operator's responsibility. Take application-specific influences
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 elastomers, by exposure tolight and heat)− Chemical attack (organic materials, e.g. plastics or elastomer, which swell, leach out or
decompose due to exposure to chemicals)! NOTICE
Risk of malfunction due to the use of unauthorized parts.
Î Only use original parts to replace worn parts.

Proof testing

7.2 Function testing
Regularly check the safety function according to the test plan drawn up by the operator.
Refer to the SIL proof test when large deviations occur or any other irregularities. The necessary documentation for this is provided by SAMSON.
The SIL proof test can be performed by SAMSON on request.
Note
Record any solenoid valve faults and e-mail (aftersalesservice@samsongroup.com) them to
SAMSON.
Î For the internal pilot supply, the permissible operating pressure from 1.4 to 6.0 bar must
be applied to port 4.
In case of external pilot supply, air with the maximum operating pressure of 6.0(10.0) bar or the maximum available operating pressure must be applied to port 4. On
using an upstream positioner, adjust it so that the maximum output pressure is available
at the positioner output.
Î Apply the nominal voltage UN specified on the nameplate to the solenoid valve.
Î Check whether the valve moves to its end position on demand.
Î De-energize the solenoid valve.
Check whether the actuator is fully vented within the demanded time (fail-safe position).
Tip
Connect a pressure gauge to check that the actuator has completely vented.
Î Record the valve transit time and compare it to the time the valve took at start-up andduring proof tests.
Proof test
A full stroke test must be performed as the proof test. The following value can be used for
Proof Test Coverage to calculate PFDavg:
PTC (Proof Test Coverage) = 95 % for a proof test

Maintenance and repair

8 Maintenance and repair
Only perform the work on the solenoid valve described in u EB 3963.
Only use the specified original mounting parts.
! NOTICE
Safety function impaired due to incorrect repair.
Î Only allow trained staff to perform service and repair work.
For devices operated in the low demand mode, a useful lifetime of 11 years (plus 1.5 years
storage time) is confirmed by TÜV Rheinland® from the date of manufacture while taking into
account the specific conditions of use specified in the Safety Manual and the Mounting andOperating Instructions.
The results of the proof test must be assessed and the maintenance scheduled based on it. In
particular, after changes (e.g. signs of aging in elastomers, changed switching times or leakage etc.), it is essential that the manufacturer performs maintenance or repair work on thedevice.
