8465.pdf
➢The manual can be altered or revised without any prior notice. Any changes in product’s
specification, design, and/or any components may not be printed immediately but until the
following revision of the manual.
➢When the manual refers to “Valve Zero / Zero” means the final valve position upon pneumatic
pressure has been fully exhausted from positioner’s OUT1 port. For example, the valve zero
position may differ between linear direct and reverse actions. (DA/RA)
➢The manual should not be duplicated or reproduced for any purpose without prior approval from
Rotork YTC Limited, Gimpo-si, South Korea.
➢In case of any other problems that are not stated in this manual, please make immediate contact
to Rotork YTC Limited.

➢Manufacturer warranty will not cover products that have been subjected to abuse, accidents,
alterations, modifications, tampering, negligence, misuse, faulty installation, lack of reasonable
care, repair or service in any way that is not contemplated in the documentation for the product,
or if the model or serial number has been altered, tampered with, defaced or removed; damages
that occurs in shipment, due to act of God, failure due to power surge, or cosmetic damage.
Improper or incorrectly performed maintenance will void this limited warranty.
➢For detailed warranty information, please contact the corresponding local Rotork YTC Limited
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 :
The ambient temperature range deviates from the standard temperature range and amounts to:
Equipment must be protected from risk of mechanical impact hazard.
Temperature class T5 / T100°C: -40°C to +60°C

2 Product Description
2.1 General
YT-3300 / 3350 / 3303 / 3301 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 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)
➢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 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).
