office or main office in South Korea.
1.3 Explosion Proof Warning (Only for Intrinsic safety type positioners)
Please ensure the unit is being used and installed in conformity with local, regional, and national
explosion proof within the proper safety barrier environment.
➢Refer to “2.6 Certifications”
➢Explosion proof type of cables and gaskets should be used, when explosion gases are present at
the installation site.
➢Positioner has 2 ports for power connection. Explosion proof type wires and packing should be
used. Blind plug is required when any port is not being used.
➢Ring terminal with surface area of more than 1.25 mm2 with M4 spring washer should be used to
connect the power.
➢For external ground terminal, ring terminal with surface area of more than 5.5 mm2 should be used.
➢Wiring in these applications shall utilize appropriate methods for Class I, Division 2 / Zone 2
➢Substitution of components may impair intrinsic safety.
➢WARNING –EXPLOSION HAZARD –Substitution of components may impair suitability for
Class I, Division 2.
➢“AVERTISSEMENT –RISQUE D'EXPLOSION –Remplacement des composants peut nuire à la
conformité de Classe I, Division 2”
➢EXPLOSION HAZARD. Do not connect or disconnect wiring unless all sources of power have
been removed or the area is known to be non-hazardous.
(French) RISQUE D'EXPLOSION. Ne pas raccorder ou débrancher le câblage à moins Toutes
les sources d'énergie ont été enlevées ou la zone est connue pour être non dangereux.
➢The enclosure of models YT-3300, YT-3301, and YT-3303 contains aluminum, which is
considered to constitute a potential risk of ignition when subjected to impact or friction. Care
must be used during installation in locating this equipment to prevent impact or friction
➢Some of the enclosure parts are made of non-metallic materials. To prevent the risk of
Electrostatic sparking, clean the enclosure only with a damp cloth.
➢The product must be installed in such a manner as to minimize the risk of impact or friction with
other metal surfaces.

➢For Intrinsically Safe installations, the product must be connected to suitably rated intrinsically
safe equipment, and must be installed in accordance with applicable intrinsically safe installation
standards.
➢Special conditions for safe use of sign “X” of ATEX / IECEx :
The ambient temperature range deviates from the standard temperature range and amounts to:
Temperature class T5 / T100°C: -40°C to +60°C
Temperature class T6 / T85°C: -40°C to +40°C
Equipment must be protected from high risk of mechanical impact hazard and high electrostatic
charge hazards.
➢FM & CSA only : Tapped Exhaust option is used when it is required to vent away Group D,
Div/Group IIA, Zone gases to a safe area. Using gases other than air must be compatible with
the YT-3300 series wetted parts.

2 Product Description
2.1 General
YT-3300 / 3350 / 3303 / 3301 / 3302 series Smart Valve Positioner accurately controls valve stroke in
response to an input signal of 4 ~ 20 mA from the controller. Built-in micro-processor optimizes the
positioner’s performance and provides unique functions such as Auto-Calibration, PID Control, and
HART Protocol Communications.
2.2 Main Features and Functions
➢LCD display enables users to monitor the positioner status.
➢User will easily understand the method of using 4 buttons because it work same in all versions of
firmware interfaces.
➢When unexpected situation like momentary blackout happens, our positioner boot-time only take
0.5 second and this can minimize the travel of valve which consequentially increase the safety of
system.
➢Positioner operates normally even there are sudden changes in supply pressure and / or high
vibration environment.
➢YT-3301 / 3302 remote positioner is stronger on high temperature and vibration environment
because it is separated into remote sensor and positioner.
➢The method of Auto Calibration is very simple.
➢As an advantage of having very low air consumption, It could greatly reduce operating costs in
large-scale plants.
➢It is compatible with most of controllers.
➢Orifices can be installed even in the field to minimize the hunting occurrence and optimize
operating conditions.
➢Various information about positioner can be processed by HART communication. (HART option)
➢"EDD and FDI files required for HART communication can be downloaded from our website
(www.ytc.co.kr) or FieldComm Group (www.fieldcommgroup.org). When using the FieldComm
Group website, please search for the Product Name on YT-3XXX."
➢Valve system becomes more stable by outputting analog feedback signal.
➢Different valve characteristics can be adjusted – Linear, Quick Open, Equal Percentage, and User
Set which user can make 5 or 18 points characterizations.
➢Tight Shut – Close and Shut - Open can be set.
➢PID parameters can be adjusted in the field without any additional communicator.
➢A/M switch can be used to direct supply air to the actuator or to manually operate the positioner
or valve without any signal.
➢Split range 4 ~ 12 mA or 12 ~ 20 mA can be set.
➢Operating temperature for remote sensor of YT-3301 / 3302 is -40 ~ 120 °C.
Operating temperature for positioners is -30 ~ 85 °C or -40 ~ 85 °C (Please check certified
explosion proof temperature)

➢Hand calibration function can set Zero point or End point manually.
➢It has IP66, Type 4X(FM) protection grade.
➢Polyester powder coating resists the corrosion process. (except YT-3350).
➢Maintenance of the positioner is easy because of modularized inner structure.
➢SIL2 certified.(For more information, see SIL Safety Instruction on homepage)
➢Suitable for use with methane or natural gas supply pressure medium for FM/CSA (only A & AG
of Explosion proof of Product code)
➢The AG option in the product code has the tapped exhaust ports to carry the gas vented from the
positioner to a safe location when the positioner is installed indoors to use methane or natural gas
as a process medium.
