nstalling Series 195 with Bracket

t is necessary to make a proper bracket to attach on the actuator yoke.

he most important considerations in the design of the bracket are as follows:

Series 195 feedback lever should be at 50% of valve stroke.

•

• Feedback level connection bar of actuator clamp should be connected in the position so that the valve stroke and the numbers carved on feedback lever are fitted.

f the bracket meets the above conditions, Series 195 can be installed very easily.

. Assemble Series 195 and bracket with bolts. Use standard bolts in bolt holes on

2 the backside of the unit.

Installation

OTICE

When the positioner is replaced or installed with the actuator, make sure of the following:

• All inputs and supply pressure to the valve, actuator and other instruments must be shut down.

The control valve must be separated from the system with a bypass valve or other

•

quipment so that the entire system does not shut down.

• No pressure remains in the actuator.

Tools For Installation

• Hexagonal wrenches

• (+) Screw driver

• (-) Screw driver

• Spanners for hexagon head bolts

Series 195 Installation

Series 195 is used for linear motion valves, such as Dwyer Instruments globe valves, using a spring return type diaphragm actuator or piston actuator. The Series 195 consists of the following components. Be sure that all the components are included.

• Series 195 main body

• Feedback lever and lever spring

• Flange nut (attached on the bottom of main shaft of Series 195 body)

• Four hexagon head bolts M8x1.25P

. After assembling Series 195 and bracket with bolts, attach it using the bolt holes

f the actuator yoke. Do not tighten completely. There must be some space.

4. Install the bar connected with Series 195’s feedback lever on the actuator clamp. The slot length between Series 195’s feedback lever is .26˝ (6.5mm), so the diameter of the connection bar should be less than .25˝ (6.3 mm).

5. Connect the air filter regulator with the actuator temporarily. Set supply pressure of air filter so that the actuator clamp is positioned at 50% of valve stroke.

Series 195 Installation Example

• Four M8 plate washers

6. Insert the connection bar attached on the actuator clamp into the slot of Series 195’s feedback lever. In order to reduce hysteresis, it should appear as shown:

. Check that the Series 195’s feedback lever is level at 50% of valve stroke. If not,

ove the bracket or feedback link until it is level. Product linearity becomes work if

m Series 195 is installed without being level at 50% of valve stroke.

8. Check the valve stroke. The numbers indicating the stroke are carved in the eries 195’s feedback lever. Set the connection bar attached on the actuator clamp

o the number on the feedback lever applicable to the valve stroke, as shown in the

ollowing picture. To set the connection bar and the number, move the bracket

f attached on Series 195 or connection bar from side to side.

. Once the Series 195 is installed according to the above procedures, tighten the

olts and nuts of the bracket and feedback lever connection bar completely.

eries 295 Installation

Series 295 is designed for rotary motion valves, such as Dwyer Instruments ball and butterfly valves, using rack and pinion, scotch yoke or complex type actuators whose stem is rotated 90°. Series 295 positioners consist of the following

omponents:

Series 295 main body

• Fork lever and lever spring to attach on actuator

• 1 bracket

and 100%, the feedback lever should not reach to the lever stopper on the backside of the Series 195 unit. If the feedback lever reaches the lever stopper, move attachment of Series 195 away from the yoke center.

After installation, operate the valve from 0 to 100% stroke using an air filter regulator on the actuator. When the stroke is both 0

Series 295 Installation Example of Namur Shaft

Installing Series 295 with Bracket

Series 295 is supplied with a standard bracket. The bracket consists of two parts and is used with a NAMUR shaft. The bracket is assembled in the factory based on .79˝ (20 mm) of actuator stem height. If the actuator stem height is higher, such as

1.18˝ (30 mm) or 1.97˝, use the table below to check hole positions.

Actuator Stem Height (H)

20 mm 30 mm 50 mm

Ex) If H is 30 mm, A-L should be locked in H:30 hole, B-L in H:20, 30, A-R in H:30, and H:20, 30 with bolts.

1. Typically actuator stem heights (H) are .79, 1.18, and 1.97 inches (20, 30, and

50 mm). After checking H, assemble brackets following previous guidelines. The bracket is set at .79˝ (20 mm) in the factory.

2. Attach the bracket to the actuator using hex bolts. The diameter of the bracket

bolt holes is .24˝ (6 mm). Using spring washers or thread lock compound so the bolts will not be loosened by vibration or impact. The direction of the bracket varies by operating conditions, but normal direction is depicted in the following picture. That is, when the piping of actuator and Series 295 is as shown in direction A, the bracket hole and indicator attached on the bottom of the Series 295 main shaft should be mounted in the same direction.

ero point without supply pressure, making it easy to check the zero point. If the

ctuator is double-acting, check whether the rotation direction of the actuator is

a clockwise or counter-clockwise, or the rotation direction of the actuator using supply pressure.

. Set the actuator stem as the initial zero point and install a fork lever as showing

n the following picture. Confirm the position of initial zero point when the actuator

tem is turned clockwise and counter-clockwise. Installation angle of the fork lever

hould be about 45 degrees based on the linear shaft. But the angle is not related

Installation Position of Fork Lever

5. Once the fork lever position is set, lock the check nuts on the bottom of the fork lever by turning clockwise. Set the upper height of the fork lever to .24 to .43˝ (6 to 11 mm) lower than the upper height of the bracket.

6. Attach the Series 295 unit to the bracket. Fix the clamping pin on the main shaft center of the Series 295 into the hole of the fork lever. Insert the connection bar attached on the main shaft lever into the fork lever slot to be locked by the fork lever spring. This is to fit the main shaft of the Series 295 to the center of the actuator stem. If they are not fitted correctly, too much force on the main shaft will greatly reduce product durability.

7. Attach the Series 295 base and the bracket with hex bolts and plate washers. It is best to lock the bracket and Series 295 together by inserting four bolts after checking the position.

iping Connection Example of Series 195 with Single Acting Actuator

Piping Connection Example of Series 295 with Single Acting Actuator

Single Acting Actuator

To operate a single acting actuator, connect OUT1 port to actuator supply pressure port. Close off the OUT2 port with the supplied 1/4˝ NPT plug.

Power Connection

CAUTION

1. Before connecting terminal, power must be shut off.

2. Use ring type terminal against oscillation, impact, etc.

3. Series 195 and 295 positioners use 4 to 20 mA DC for power. Minimum supply

current is 3.2 mA (standard type) and 3.8 mA (HART

type). Maximum supply current must not exceed 24 mA. In order to protect the Smart Positioner, the ground terminals should be grounded.

4. Use twisted cable with conductor sectional area at least 0.0019 in

(1.25 mm2), and suitable for 600V as on conductor table of NEC Article 310. Outer diameter of cable should be .25 to .39˝ (6.35 to 10 mm). Use shielded wire against electromagnetic waves and noise.

5. Do not install the cable near equipment such as a high-capacity transformer or motor.

PIPING CONNECTION

NOTICE

1. To prevent ingress of moisture, oil and dust, give careful consideration to the choice of supply pressure compressor and

piping.

2. It is recommended to attach a filter or air filter regulator in front of the supply port of the Series 295 unit..

Conditions of Supply Pressure

1. Dry air with a dew point that is at least 50°F (10°C) lower than that of the ambient temperature.

ariable Orifice

unting can occur if the actuator volume is too small. In this case, adjust the

ariable orifice using a (-) flathead screwdriver. Hunting is prevented by reducing

he flow rate of supply pressure transmitted to the actuator.

Auto Calibration and Basic Operations

AUTION

Buttons Operations

Series 195 and 295 positioners perform various functions using four buttons. The position of the buttons is shown below: <Enter> : is used to go to the main menu, save adjusted parameter values, or

hoose sub menus.

Esc> : is used to return to previous menu.

UP> : is used to move to another menu or change parameter values.

< <DOWN> : is used to move to another menu or change parameter values.

ince this makes the valve or actuator move, before auto

alibration, the valve must be separated from the entire system.

3. For use with inside ground, open cover by loosening the four screws of positioner cover.

4. In order to maintain the ground connection, use a ring type ground cable terminal to prevent it from coming out.

S/E Button (SUP/EXT Buttons)

There are “SUP” and “EXT” buttons next to the LCD display of the Series 195 and 295 positioners. If the “SUP” button is pressed, air pressure will be supplied to the actuator. If the “EXT” button is pressed, the air pressure will be exhausted from the actuator. This function is used when diagnosing actuator operation.

RUN mode

After connecting the power to the positioner, the following is displayed on the LDC in 6 seconds.

RUN on the bottom line means that the Smart Positioner adjusts valve stroke based on an outside signal (4 to 20 mA), and PV refers to the number on the LCD. In RUN mode, valve stroke is changed according to input signal.

Run PV

Run SV %

Run SV mA

Run MV

Run Err

There are six options in RUN mode. In order to change display, push <ESC> and <UP> at the same time. When the buttons are pushed, display order is changed. If the <ESC> and <DOWN> buttons are pushed simultaneously, the order is opposite and if <ESC> is pushed only, display returns to RUN mode.

First Auto Calibration

First auto calibration is usually used when the positioner has not been set, such as the initial setting with valve at the valve company, or replacement with other product in the field. In this case, all parameters are set by using the AUTO2 calibration.

CAUTION

AUTO1 calibration. This is because the valve company sets optimum parameters, so it is better that those registered parameters are not changed by AUTO1 calibration.

1. Connect power. Any values between 4 to 20 mA (DC) can be used for power. After connecting power, ‘READY 3, 2, 1’ message appears on the LDC, which means preparing to operate PCB circuit and parts. The following message is displayed in 6 seconds. Push <ENTER> for 6 seconds at RUN mode and AUTO CAL message should appear.

2. Push <ENTER> and then AUTO1 mode is started.

3. Push <DOWN> and AUTO2 mode is displayed.

4. Push <ENTER> at AUTO2 mode. Auto 2 calibration is started and the next modes are displayed in order on the LCD. Normally it will take 3 to 5 minutes for auto calibration in AUTO2 mode, but it can be different based on actuator’s volume.

Parameter Mode (PARAM) Parameter Types

There are four types in Parameter mode: Dead Zone, KP, KI, and KD.

hese values are reflected as soon as they are changed, therefore the appropriate

alues are found by checking the valve’s motion in real time.

Dead Zone (dEAdZONE)

This is the range of error % that the positioner is not adjusted. Hunting or oscillation due to friction between the stem and packing is prevented by this parameter.

his is a proportion constant value that is correction by error %. If this value is too

ig, there can be hunting, even though it finds position by the input signal. If the

b value is too small, accuracy gets worse.

This is an integral constant value adding or subtracting the correction that is

orrected error % on the previous correction signal. If this value is too big, there can

e oscillation. If it is too small, the time to find the exact position increases.

This is a differential constant value adding the previous correction signal with the changing correction signal by the error % change rate.

6. Push <ENTER> to save the value. +EAdZONE message appears on LCD.

Auto 2 Calibration (AUTO2)

All parameters necessary to operate the valve are set. This calibration is used when the positioner is first installed with valve. Refer back to First Auto Calibration.

Auto 3 Calibration (AUTO3)

All parameters necessary to operate the valve are set except zero and end point. This function is used to re-execute auto calibration without changing the zero and end point after adjusting them manually.

1. Push <DOWN> at AUTO2 and AUTO3 is displayed.

2. Push <ENTER> and AUTO3 calibration is started. The remaining procedures of this calibration are the same as other calibrations.

Manual Mode

Manual mode is used to raise or lower the valve stem manually. In this mode, valve stroke is adjusted only by operating buttons, not by the current input signal. This mode does not affect controlling data registered in the positioner. It only is used to move the valve stem up and down.

1. Push <ENTER> at RUN mode until AUTO CAL message is displayed.

2. Push <DOWN> and MANUAL mode is displayed.

djustment of User Characteristics (USER SET)

. Push <ENTER> at VALVE mode and ACT RA or ACT DA is displayed.

. Push <DOWN> twice, then USER SET mode is started.

. Push <ENTER>. *PO SET mode is displayed. In this mode, users can adjust the

first point of characteristic in 16 points. The number on the LCD is the valve stroke percentage set to P0.

4. Adjust the valve stroke percentage using <UP> or <DOWN>.

. Save it with <ENTER>. While P0 value is being saved, *P1 SET mode is

isplayed.

. *P1 SET mode is used to adjust the second point characteristic in 16 points.

djustment method is the same as P0* SET mode.

7. Save the valve stroke percentage from P2 to P15 SET mode, save it with <ENTER>.

8. After adjustment of valve stroke percentage at *P15 SET mode, save it with

User Characteristics (USER SET)

When a specific characteristic is needed but not included in the above

haracteristics, the user can make a specific characteristic curve by choosing 16

oints voluntarily according to the field conditions the user’s need.

Tight Shut Open (TSHUT OP)

This allows the user to fully open valve at any value around the 20 mA current input signal.

Tight Shut Close (TSHUT CL)

This allows the user to completely close valve at value around 4 mA input signal from outside.

Split Range Control (SPLIT)

This allows the user to control entire stroke with input signals of 4 to 20 mA, 4 to 12 mA or 12 to 20 mA.

Adjustment of Acting Type (ACT)

1. Push <ENTER> at RUN mode for six seconds and then AUTO CAL mode is displayed. Push <DOWN> four times to go into VALVE mode.

2. Push <ENTER> and ACT RA (in case of RA) is displayed.

3. Push <ENTER> again, then *ACT RA is displayed.

4. Adjust to *ACT DA by pushing <UP> or <DOWN> and save it with <ENTER>. +ACT DA message appears.
