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 feedback 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 Custom which user can make 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 sensor module 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.

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.

5. Connection – Power

5.1 Safety

Conduit entry connection tap is G(PF) 1/2.

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 3.5 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.

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 Proximity

limit switch option, separate 8.2V DC must be supplied.

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.

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”.

※ Please note that the direction of “—“ slot of A/M switch has nothing to do with the direction

of “M” or “A”.

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.

8.9.1 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 of PST in the SCHD mode.

9. Error and Warning Code

Below error and warning codes can be checked from “View” mode if there are any problems

while using the product.

9.1 Error code

Error codes are indicated if the positioner cannot be controlled, malfunctions or becomes

imprecise.

Error Code Code Description and Cause Action

MT ERR L

Indicates that due to wrong

positioning and installation of the

positioner, there is a chance that

the feedback lever and the

positioner’s stopper could collide

when the lever is at 0% during

auto calibration.

when this error is detected, auto

calibration is aborted and this

message is indicated

immediately on LCD display.

Set the feedback lever

horizontally when at 50%.

Re-adjust the position of the

positioner by referring to the

following effective range of the

feedback lever’s angle

(YT-3300 / 3350 linear : 60

deg., YT-3303 / 3301 linear :

30 deg., rotary : 90 deg.)

MT ERR H

Indicates that due to wrong

positioning and installation of the

positioner, there is a chance that

the feedback lever and the

positioner’s stopper could collide

when the lever is at 100% during

auto calibration.

when this error is detected, auto

calibration is aborted and this

message is indicated

immediately on LCD display.

CHK AIR

Indicated when the valve is not

moving despite the positioner

has given “Full Open” signal

during auto calibration.

when this error is detected, auto

calibration is aborted and this

message is indicated

immediately on LCD display..

Check if pressure is being

supplied normally to the

positioner.

RNG ERR

Indicated when the feedback

lever’s angle used is excessively

small during auto calibration.

when this error is detected, auto

calibration is aborted and this

message is indicated

immediately on LCD display.

Re-install the positioner by

moving it towards the actuator

stem so that the angle use of

the feedback lever becomes

larger.

C

Indicated if the deviation between

SV and PV is above 10% and is

continued for over one minute.

Indicated when the valve does not

operate, friction is extremely high or

when the air regulator’s set pressure

is too low.

Can be checked from “Error”

category in View mode. (Refer to

section 8.10)

Re-perform auto-calibration.

Check air regulator’s set pressure

and re-adjust to appropriate

pressure.

D

Accumulated I value is I max or

min’s limit.

Degree of precision is low.

Indicated if valve’s friction is

extremely high or set pressure of air

regulator has been changed.

Can be checked from “Error”

category in View mode. (Refer to

section 8.10)

Re-perform auto-calibration

Check air regulator’s set pressure

and re-adjust to appropriate

pressure.

9.2 Warning code

Below codes are indicated when the positioner can be controlled, but there is a possibility of

malfunctioning or degree of precision has dropped.

Warning Code Code Description and Cause Action

B

PV Span – PV Zero range is below

500.

Feedback lever’s angle use is too

low.

Can be checked from “Error”

category in View mode. (Refer to

section 8.10)

Re-position the positioner so that

the angle use of the feedback

lever is larger than current angle.

Then, perform AUTO1 calibration.

F

Full open & Full close time is less

than 1 second.

Size of the actuator is too small.

Can be checked from “Error”

category in View mode. (Refer to

section 8.10)

Use orifice and lower the flow

rate.

Or replace the actuator with

bigger size.

G

PV is set below 100.

Feedback lever’s angle use is set

too high.

Can be checked from “Error”

category in View mode. (Refer to

section 8.10)

Re-position the positioner so that

the angle use of the feedback

lever is smaller than current

angle. Then, perform AUTO1

calibration. H

PV is set above 4000.

Feedback lever’s angle use is set

too high.

Can be checked from “Error”

category in View mode. (Refer to

section 8.10)
