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.
➢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”

2 Product Description
2.1 General
YT-3300 / 3350 (PA/FF) series Smart Valve Positioner accurately controls valve stroke in response to
an input signal of Communication from the controller. Built-in micro-processor optimizes the
positioner’s performance and provides unique functions such as Auto-Calibration, Profibus PA or
Foundation fieldbus 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.
➢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.
➢Different valve characteristics can be adjusted – Linear, Quick Open, Equal Percentage, and User
Set which user can make 5 or 11 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.
➢Operating temperature for positioners is -30 ~ 85 °C or -40 ~ 85 °C (Please check certified
explosion proof temperature)
➢It has IP66 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)

3 Installation
3.1 Safety
When installing a positioner, please ensure to read and follow safety instructions.
➢Any input or supply pressures to valve, actuator, and / or to other related devices must be turned
off.
➢Use bypass valve or other supportive equipment to avoid entire system “shut down”.
➢Ensure there is no remaining pressure in the actuator.
➢The positioner has a vent cover to exhaust internal air and drain internal condensation water.
When installing the positioner, make sure the vent cover must be facing downward. Otherwise,
the condensation water could cause damages to PCB.
Fig. 3-1: The correct positions of a vent cover
※Installed in accordance with the National Electrical Code(NEC), ANSI/NFPA 70, or
CEC Part 1 as applicable.(FM approved product)
3.2 Tools for installation
➢Hex key set for hex socket cap bolts
➢(+) & (-) Screw drivers
➢Spanners for hexagonal-head bolts

3.3 Linear positioner Installation
Linear positioner should be installed on linear motion valves such as globe or gate type which uses
spring return type diaphragm or piston actuators.
3.3.1 Linear positioner Installation of Standard lever type
Fig. 3-2: Installation of standard lever type example
Before proceeding with the installation, ensure following components are available.
➢Positioner
➢Feedback lever and lever spring
➢M6 nut and spring washer (fastening feedback lever to a main shaft)
➢Bracket, bolts and washers for positioner or sensor – not supplied with the positioner
➢Connection bar – not supplied with the positioner
3.3.1.1 Safety
Proper bracket must be made in order to adapt the positioner on the actuator yoke.
Please consider following important points when a bracket is being designed.
➢Positioner’s feedback lever must be vertical to the valve stem at 50 % of the valve stroke.
➢The connection bar of the actuator clamp for the feedback lever should be installed in such a way
that the valve stroke length coincides with the corresponding figure in “mm” marked on the
feedback lever. Improper setting may cause poor linearity

3.3.1.2 Standard lever type positioner Installation Steps
1) Assemble the positioner or remote sensor with the bracket made in previous step by fastening the
bolts.
Fig. 3-3: Standard Lever Type
2) Attach the positioner (or remote sensor) with the bracket to the actuator yoke
– DO NOT TIGHTEN THE BRACKET COMPLETELY.
3) Connect connection bar to the actuator clamp. The hole gap on the feedback lever is 6.5 mm so
the connection bar’s outer diameter should be less than 6 mm.
4) Connect an air-filter regulator to the actuator temporarily. (Use the auto manual switch to make it
easier to set up. For more information, see 6.1) Supply enough air pressure to the actuator in order
to position the valve stroke at 50 % of the total stroke.
Fig. 3-4: Standard Lever Type

Ver. 1.00 18
5) Insert the connection bar between the feedback lever and lever spring. The connection bar must
be located upward from the lever spring as shown below left figure. If it is located downward from
the lever spring as shown below right figure, the connection bar or the lever spring will be worn out
quickly because of excessive strong tension.
Fig. 3-5: Proper way to insert connection bar between feedback lever and lever spring
6) Check if feedback lever is vertical to the valve stem at 50 % of the valve stroke. If it is not vertical,
adjust the bracket or the connection bar to make vertical. Improper installation may cause poor
linearity.

7) Check the valve stroke. The stroke numbers are engraved on the feedback lever of the positioner.
Position the connection bar at the number on the feedback lever which corresponds with the
desired valve stroke. To adjust, move the bracket, the connection bar or both.
※ The effective linear lever angle of positioner is 60 degree
Stroke : 75 mm
Stroke : 45 mm

8) After installing the positioner, operate the valve from 0 % to 100 % stroke by using direct air to the
actuator. On both 0 % and 100 %, the feedback lever should not touch the lever stopper, which is
located on the backside of the positioner. If the feedback lever touches the stopper, the positioner
should be installed further away from center of the actuator.
Fig. 3-8: Feedback lever should not touch lever stopper on 0 % ~ 100 % valve stroke.
9) After the installation, tighten all of the bolts on the bracket and the connection bar.

3.3.2 Installation of Adapter lever type (on tubeless actuator)
Fig. 3-9: Installation of adapter lever type example
Before proceeding with the installation, ensure following components are available.
➢Positioner
➢Feedback lever
➢M6 nut and spring washer (fastening feedback lever to a main shaft of positioner)
➢O-ring(Connect out1 port of positioner and actuator) – not supplied with the unit
➢1/4 plug – not supplied with the unit
➢Adapter holder – not supplied with the unit
➢2 pcs x bolts (M8 x 1.25P) – not supplied with the unit
※When using adapter lever, generally tubeless actuator which doesn’t requires pipe between
actuator and positioner is used. Therefore, in this section, installation method of tubeless actuator
and positioner will be introduced like below.
3.3.2.1 Safety
➢Positioner’s feedback lever must be vertical to the valve stem at 50 % of the valve stroke.
➢Adapter of feedback lever should be installed in such a way that the valve stroke length coincides
with the corresponding figure in “mm” marked on the feedback lever.
