specialist personnel who have been authorized by the plant operator accordingly.
➢The manual should be provided to the end-user.
➢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.
➢Positioner is an accessory of the control valve, so please make sure to read the applicable
instruction manual of the control valve prior to installation and operation.
1.2 Manufacturer Warranty
➢For the safety, it is important to follow the instructions in the manual. Manufacturer will not be
responsible for any damages caused by user’s negligence.
➢Any modifications or repairs to the product may only be performed if expressed in this manual.

prior consultation with Rotork YTC Limited will not be compensated. If any alterations or
modifications are necessary, please contact Rotork YTC Limited directly.
➢The warranty period of the product is (18) months from the date of shipment unless stated
otherwise. Date of shipment can be checked by providing the LOT NO. or SERIAL NO. to us.
➢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 1 port for power connection. Explosion proof type wires and packing should be
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.
➢The enclosure of the product 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: -30 °C to +60 °C
Temperature class T6: -30 °C to +40 °C.
Equipment must be protected from high electrostatic charge hazards and placed with a warning
marking to be cleaned only with damp cloth.

2 Product Description
2.1 General
YT-3100 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.
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.
➢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.
➢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 21 points characterizations.
➢Tight Shut – Close and Shut - Open can be set.
➢PID parameters can be adjusted in the field without any additional communicator.
➢Split range 4 ~ 12 mA or 12 ~ 20 mA can be set.
➢Operating temperature for positioners is -30 ~ 85 °C (Please check certified explosion proof
temperature in case of Ambient temperature)
➢Hand calibration function can set Zero point or End point manually.
➢It has IP66 protection grade.
➢Polyester powder coating resists the corrosion process.
➢Maintenance of the positioner is easy because of modularized inner structure.
