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 4~20mA 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 4~12mA or 12~20mA can be set.

Operating temperature for remote sensor of YT-3301 is -40 ~ 120.

Operating temperature for positioners is -30 ~ 85 or -40 ~ 85 (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).

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.

6. Attach the positioner to the bracket. <Only fork lever type of YT-3300R / 3350R / 3303R: Fix the

clamping pin (5mm Dia.) into the fork lever slot and insert center pin (2mm Dia.) of the main shaft

of the positioner into the hole of center of the fork lever. The clamping pin will be locked to the

fork lever spring.> Setting alignment of center of main shaft of the positioner and center of the

actuator’s stem is very important. Poor alignment of the main shaft and the actuator’s stem

decreases the positioner’s durability due to unnecessary forces on the main shaft.

4 Connection — Air

4.1 Safety

Supply pressure should be clean and dry air – avoiding moisture, oil and dust.

Always recommended to use air filter regulator (i.e. YT-200 series).

Rotork YTC Limited has not tested positioner’s operation with any other gases other than

clean air. Please contact Rotork YTC Limited for any questions.

4.2 Supply Pressure Condition

Dry air with dew point of at least 10 lower than ambient temperature.

Avoid from dusty air. Use 5 micron or smaller filter.

Avoid oil.

Comply with ISO 8573-1 or ISA 7.0.01.

Supply pressure range is 0.14 ~0.7 MPa (1.4 ~ 7 bar)

Set air filter regulator’s pressure level 10% higher than actuator’s spring range pressure.

4.3 Piping Condition

Ensure inside of pipe is clean of obstructions.

Do not use pipeline that is squeezed or shows any type of damamges.

Pipeline should have more than 6mm of inner diameter (10mm outer diameter) to maintain flow

rate.

The length of pipeline system should not be extremely long. Longer pipeline system may affect

flow rate due to the friction inside of the pipeline.

5 Connection – Power

5.1 Safety

Before connecting terminal, ensure that the power is off completely.

Please use ring terminal to protect against vibration or any other external impact.

Positioner usually uses 4~20mA DC. Minimum ampere of input signal of standard type positioner

is 3.2 mA and HART internal type positioner’s minimum ampere of input signal is 3.8 mA but

maximum ampere of input signal should be 24mA or under.

Compliance voltage of current source must be Min. 10V and Max. 28V. If the length of the supply

cable between the current source and the positioner is long, or if there is a filter or safety barrier,

then consider using a current source which could supply higher Compliance voltage.

Positioner with PTM options must be supplied with 9~28V DC separately. For mechanical limit

switch option, separate 12~30V DC must be supplied. For inductive proximity limit switch option,

separate 8.2V DC must be supplied.

DO NOT connect Voltage source (9~28V DC) to Input (4~20mA DC) terminal (IN+, IN-) as it will

cause PCB failure.

Positioner should be grounded.

Please use twisted cable with conductor section are 1.25mm2 and that is suitable for 600V

(complying with the conductor table of NEC Article 310). The outer diameter of the cable should

be between 6.35 ~ 10mm. Use shield wire to protect against electro-magnetic field and noise.

Please do not install the cable near high noise equipment, such as high-capacity transformer or

motor.

Ver. 1.30 50

6.2 A/M switch adjustment

1. On the right hand bottom of positioner, there is A/M switch (Auto/Manual). A/M Switch allows the

positioner to be functioned as by-pass. If the switch is turned clockwise (toward “A”) and it is

fasten tightly, then the supply pressure will be transferred to actuator through outport by

positioner control. On the other hand, if the switch is turned counter-clockwise (toward “M”), it is

loosened, then the supply pressure will be directly supplied to the actuator regardless of

positioner control. It is extremely important to check the allowed pressure level of the actuator

when the switch is loosened.

2. Check whether the supply pressure is too high.

3. After using “Manual” function, A/M switch should be returned to “Auto”.

6.3 Orifice Installment

Hunting can be occurred when the actuator ’s volume is too small. In order to prevent hunting, orifice

can be used.

6.3.1 Plate type Orifice Installment (except YT-3303)

By installing the plate type orifice, the flow rate

of the supply pressure to actuator can be

reduced. The diameter of orifice hole is 1 mm.

Fig. 6-4: Plate type Orifice installment

6.3.2 Variable Orifice Adjustment (Only YT-3303)

By adjusting the orifice, the flow rate of the supply pressure to actuator can be adjusted. Please use

(-) driver to adjust the orifice. When slot (-) of the orifice is vertical like the below left figure, the flow

rate becomes maximum. When slot (-) of the orifice is horizontal like the below right figure, the flow

rate becomes minimum.

8.8.9 Interpolation Mode (ITP ON / OFF)

In case of linear positioner, interpolation method is used to compensate for the error that occurs

when converting the linear motion of the actuator into rotary motion of the feedback lever. After the

auto calibration is completed, the angle of feedback lever is automatically checked. If the angle is

more than 20 °, the ITP function is turned on as a correction value that matches the angle of use of

the feedback lever. However, if the angle of use from feedback lever is 20 ° or less, or in case of

rotary positioner, ITP function will be turned OFF.

In this mode, user can could manually change ITP ON or OFF.

※ The below shows that the user manually change ITP ON into OFF.

8.9.1 PST Introduction

Unlike FST (Full Stroke Test) where a valve such as an emergency shut-off valve is physically closed

and opened in full,

PST is a method used to test a percentage of the possible failure of the valve by slightly closing and

opening the valve when testing.

Rather than only performing FST regularly, PST is alternately applied with FST which could reduce

the overall cost and risk.

YT-3300 positioner includes PST function and it could operate while offline without any other

software.

Also, PST function and results could be set and checked through HART communication.

When PST runs by PST NOW or SCHD, if valve position is in the range of TOL from START PO,

Positioner supply or vent air until the valve reach the TARGET 1, 2. But PST test will stop if valve

position goes out of the TOL or doesn’t reach TARGET1, 2 within the LIMIT TM. After the valve

position reach the TARGET 1, 2, the valve will pause during the LATENCY and move back to the

START PO. The valve will be under ready state during the INTERVAL time after completing 1 cycle
