1 Introduction
1.1 General Information for the users
Thank you for purchasing Rotork YTC Limited products. Each product has been fully inspected after
its production to offer you the highest quality and reliable performance. Please read the product
manual carefully prior to installing and commissioning the product.
➢Installation, commissioning, and maintenance of the product may only be performed by trained
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.
Injuries and physical damages caused by customer’s modifying or repairing the product without a
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.

➢In case of Fail Freeze product, it keeps the position of current valve in case of input current signal
failure. However, please do not leave it in that state for a long time and take immediate action to
restore the system. There is no fault in the positioner, but it is often reported that the valve is out
of position due to an unexpected leak in the pipe or actuator.
➢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 1.25mm2 with M4 spring washer should be used to
connect the power.
➢For external ground terminal, ring terminal with surface area of more than 5.5mm2 should be used.
➢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 :
Impact testing on light transmitting parts was carried out with low impact energe. Applications with
a high risk of impact or with risk of high impact energies are to be avoided.
The ambient temperature range deviates from the standard temperature range and amounts:
Temperature class T5 / T100°C: -40°C to +60°C
Temperature class T6 / T85°C: -40°C to +40°C

2 Product Description
2.1 General
YT-2500 / 2550 / 2501 series Smart Valve Positioner accurately controls valve stroke in response to
an input signal of 4~20mA from the controller. Built-in micro-processor optimizes the positioner’s
performance and provides unique functions such as Auto-Calibration, PD Control, and HART
Protocol Communications.
2.2 Main Features and Functions
➢When Input signal fails, Positioner keeps the current position of the valve stroke without any
additional device. (Fail Freeze option)
➢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.
➢Positioner operates normally even there are sudden changes in supply pressure and / or high
vibration environment.
➢YT-2501 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.
➢Variable orifices can be used to minimize the hunting occurrence and optimize operating
conditions.
➢Various information about positioner can be processed by HART communication. (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 points or 18 points characterizations.
➢Tight Shut – Close and Shut - Open can be set.
➢PD parameters can be adjusted in the field without any additional communicator.
➢Split range 4~12mA or 12~20mA can be set.
➢Operating temperature for remote sensor of YT-2501 series is -40 ~ 120°C.
Operating temperature for positioners is -30 ~ 80°C (Please check certified explosion proof
temperature)
➢Hand calibration function can set Zero point or End point manually.
➢It has IP66 protection grade.
➢Polyester powder coating resists the corrosion process. (except YT-2550)
➢Maintenance of the positioner is easy because of modularized inner structure.
