Safety instructions and measures
1 Safety instructions and measures
Intended use
TheType3967SolenoidValveismountedontopneumaticlinearorrotaryactuatorstocon-
trol them. Upon failure of the air supply, the solenoid valve vents the actuator, causing the
valve to move to the fail-safe position determined by the actuator. The device is designed to
operateunderexactlydenedconditions(e.g.operatingpressure,temperature).Therefore,
operators must ensure that the solenoid valve is only used in applications where the operat-
ing conditions correspond to the technical data. In case operators intend to use the solenoid
valveinapplicationsorconditionsotherthanthosespecied,contactSAMSON.
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.
ÎRefertothetechnicaldataandnameplateforlimitsandeldsofapplicationaswellas
possible uses.
Reasonably foreseeable misuse
The solenoid valve is not suitable for the following applications:
− Useoutsidethelimitsdenedduringsizingandbythetechnicaldata
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing maintenance activities not described
Qualications of operating personnel
The solenoid valve must be mounted, started up, serviced and repaired by fully trained and
qualiedpersonnelonly;theacceptedindustrycodesandpracticesmustbeobserved.Ac-
cording 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 experience as well as their knowledge of the
applicable standards.
Explosion-protected versions of this device must 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
Personal protective equipment is not required to mount or operate the solenoid valve. Work
on the control valve may be necessary when mounting or removing the solenoid valve.
ÎObservetherequirementsforpersonalprotectiveequipmentspeciedinthevalvedocu-
mentation.
ÎCheck with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions,conversionsorothermodicationsoftheproductarenotauthorizedbySAMSON.
They are performed at the user's own risk and may lead to safety hazards, for example.
Furthermore, the product may no longer meet the requirements for its intended use.
Warning against residual hazards
Thesolenoidvalvehasadirectinuenceonthecontrolvalvewhenithasbeeninstalled.To
avoid personal injury or property damage, plant operators and operating personnel must
prevent hazards that could be caused in the control valve by the process medium, the operat-
ing pressure, the signal pressure or by moving parts by taking appropriate precautions. Plant
operators and operating personnel must observe all hazard statements, warning and caution
notes in these mounting and operating instructions, especially for installation, start-up and
service work.
Responsibilities of the operator
Operators are responsible for proper use and compliance with the safety regulations. Opera-
tors are obliged to provide these mounting and operating instructions as well as the refer-
enced documents to the operating personnel and to instruct them in proper operation. Fur-
thermore, operators must ensure that operating personnel or third parties are not exposed to
any danger.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
wellasthereferenceddocumentsandobservethespeciedhazardstatements,warnings
and caution notes. Furthermore, operating personnel must be familiar with the applicable
health, safety and accident prevention regulations and comply with them.

Safety instructions and measures
1.1 Notes on possible severe personal injury
DANGER
!
Risk of fatal injury due to electric shock.
Before starting up the solenoid valve, electrical installation work must be performed. An
electric shock due to incorrect work practices may cause fatal injuries.
ÎBefore connecting wiring, performing any work on the device or opening the device,
disconnect the supply voltage and protect it against unintentional reconnection.
ÎFor electrical installation, observe the relevant electrotechnical regulations and the
accident prevention regulations that apply in the country of use.
ÎInGermany,observetheVDEregulationsandtheaccidentpreventionregulationsof
the employers’ liability insurance.
Risk of fatal injury due to the ignition of an explosive atmosphere.
Incorrect installation, operation or maintenance of the solenoid valve in potentially ex-
plosive atmospheres may lead to ignition of the atmosphere and ultimately cause fatal
injuries.
ÎThefollowingregulationsapplytoinstallationinhazardousareas:EN60079-14:
2008(VDE0165,Part1).
ÎInstallation, operation or maintenance of the solenoid valve must only be performed
by personnel who has undergone special training or instructions or who is autho-
rized to work on explosion-protected devices in hazardous areas.
ÎObservethetypeofprotectionandtheconditionsforcontrolspecicforthetypeof
protectionaccordingtotheEUtypeexaminationcerticate.
ÎReadthespecialinstructionsconcerningexplosionprotection(seesection1.4).

EB 3967 EN 9
Safety instructions and measures
1.2 Notes on possible personal injury
WARNING
!
Risk of personal injury due to moving parts on the valve.
During operation and when the solenoid valve is triggered, the valve moves through its
entiretravelrange.Injurytohandsorngersispossibleiftheyareinsertedintothe
valve.
ÎWhilethevalvemoves,donotinserthandsorngersintothevalveyokeanddonot
touch any moving valve parts.
Intrinsic safety rendered ineffective in intrinsically safe devices.
Every time the positioner is operated, even not within the plant (e.g. during maintenance,
calibration and work on equipment), it must be ensured that the conditions for intrinsical-
ly safe circuits are observed.
ÎOnly connect intrinsically safe devices intended for use in intrinsically safe circuits to
certiedintrinsicallysafeinput-connectedunits.
ÎDo not place intrinsically safe devices back into operation that were connected to
intrinsicallysafeinput-connectedunitswithoutcertication.
ÎDonotexceedthemaximumpermissibleelectricvaluesspeciedintheEUtypeex-
aminationcerticateswheninterconnectingintrinsicallysafeelectricalequipment(Ui
or U0, lior I0, Pior P0, Cior C0and Lior L0).

Safety instructions and measures
1.3 Notes on possible property damage
NOTICE
!
Risk of damage to the solenoid valve due to incorrect mounting position.
ÎDo not mount the solenoid valve with the vent opening facing upward.
ÎDo not seal the vent opening when the device is installed on site.
Risk of damage to the solenoid valve due to impermissible pressures.
ÎDo not connect a supply pressure to the solenoid valve that exceeds the maximum
supply pressure.
Incorrect assignment of the terminals will damage the solenoid valve and will lead to
malfunction.
For the solenoid valve to function properly, the prescribed terminal assignment must be
observed.
ÎConnect the electrical wiring to the solenoid valve according to the prescribed termi-
nal assignment.
1.4 Special instructions concerning explosion protection
Equipment for use in zone2/zone22
