Structure
The structure of the 185 is shown below. The Series 285 structure is the same as
the linear model without the feedback lever.
Installation
Note: 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 equipment 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 185 Installation
Series 185 is used for linear motion valves such as Dwyer Instruments’ globe
valves using a spring return type diaphragm actuator or piston actuator. The
Series 185 consists of the following components. Be sure that all the components
are included.
1. Series 185 main body
2. Feedback lever and lever spring
3. Flange nut (attached on the bottom of main shaft of Series 185 body)
4. Four hexagon head bolts M8x1.25P
5. Four M8 plate washers
Installing Series 185 with Bracket
It is necessary to make a proper bracket to attach on the actuator yoke.
The most important considerations in the design of the bracket are as follows:
- Series 185 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. If the bracket meets the above conditions, Series 185 can be installed very
easily.
2. Assemble Series 185 and bracket with bolts. Use standard bolts in bolt holes
on the backside of the unit.
Installing Series 185 with Bracket
3. After assembling Series 185 and bracket with bolts, attach it using bolt holes of
actuator yoke. Do not tighten completely, there must be some space.
4. Install bar connected with Series 185’s feedback lever on the actuator clamp.
The slot length between Series 185’s feedback lever is .26˝ (6.5 mm), 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.

6. Insert the connection bar attached on the actuator clamp into the slot of Series
185’s feedback lever. In order to reduce hysteresis, it should appear as shown:
7. Check that the Series 185’s feedback lever is level at 50% of valve stroke. If
not, move bracket or feedback link until it is level. Product linearity becomes work
if Series 185 is installed without being level at 50% of valve stroke.
8. Check valve stroke. The numbers indicating stroke are carved in the Series
185’s feedback lever. Set the connection bar attached on the actuator clamp to
the number on the feedback lever applicable to valve stroke as shown in the
following picture. To set the connection bar and the number, move the bracket
attached on Series 185 or connection bar from side to side.
NOT : After installation, operate the valve from 0 to 100% stroke using an air
filter regulator on the actuator. When the stroke is both 0 and 100%, the feedback
lever should not reach to the lever stopper on the backside of the Series 185 unit.
If the feedback lever reaches the lever stopper, move attachment of Series 185
away from the yoke center.
9. Once the Series 185 is installed according to the above procedures, tighten the
bolts and nuts of the bracket and feedback lever connection bar completely.
Series 285 Installation
Series 285 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 285 positioners consist of the following
components:
Series 285 main body
Fork lever and lever spring to attach on actuator
1 bracket

Installing Series 285 with Bracket
Series 285 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˝ (50 mm), reassemble the bracket adjusting to the
actuator stem height. Refer to the table below to check hole positions.
x) 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˝ (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 bracket to the actuator using hex bolts. The diameter of the bracket bolt
holes are .24˝ (6 mm). Use 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 285 is as shown in direction A, the
bracket hole and indicator attached on the bottom of the Series 285 main shaft
should be mounted in the same direction.
3. Set the rotation position of the actuator stem as the initial zero point, which is
0% stroke. For a spring return type actuator, the actuator stem is always rotated
to the zero point without supply pressure, making it easy to check the zero point.
If the actuator is double-acting, check whether the rotation direction of the
actuator is clockwise or counter-clockwise, or the rotation direction of the actuator
is using supply pressure.
4. Set the actuator stem as the initial zero point and install a fork lever as
showing in the following picture. Confirm the position of initial zero point when
actuator stem is turned clockwise and counter-clockwise. Installation angle of fork
lever should be about 45 degrees based on the linear shaft. But the angle is not
related to NAMUR shaft.
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 Series 285 unit to the bracket. Fix the clamping pin on the main shaft
center of the Series 285 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 285 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 Series 285 base and the bracket with hex bolts and plate washers. It is
best to lock the bracket and Series 285 together by inserting four bolts after
checking the position.

6. Be sure not to change the polarity of the terminals.
Inner Terminal Connection to Ground
1. The ground is necessary for the safety of the positioner and system.
2. The ground terminals are inside the terminal in the center of the terminal plate
and outside terminal beside outer cable entry. Use any ground terminal that is
available and resistance must be less than 100 Ω.
Ground Terminal Connection
3. For use with inside ground, open cover by loosening the four M4 bolts of
positioner cover.
4. In order to maintain the ground connection, use a ring type ground cable terminal
to prevent it from coming out.
Variable rifice
Hunting can occur if the actuator volume is too small. In this case, adjust the
variable orifice using a (-) flathead screwdriver. Hunting is prevented by reducing
the flow rate of supply pressure transmitted to the actuator.

Auto Calibration and Basic perations
Buttons perations
Series 185 and 285 positioners perform various functions using four buttons. The
position of the buttons is shown below:
<nter> : It is used to go to the main menu, save adjusted parameter values, or
choose sub menus.
< sc> : It is used to return to previous menu.
<UP> : It is used to move to another menu or change parameter values.
<DOWN> : It is used to move to another menu or change parameter values.
RUN mode
After connecting the power to the positioner, the following is displayed on the
LCD 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.
There are six options in RUN mode. In order to change display < SC> and <UP>
at the same time. When the buttons are pushed, display order is changed. If the
< SC> and <DOWN> buttons are pushed simultaneously, the order is opposite
and if < SC> 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 AUTO2
calibration.
1. Connect power. Any values between 4 to 20 mA (DC) can be used for power.
After connecting power, ‘R ADY 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 < NT R> for 6 seconds at RUN mode, and AUTO
CAL message should appear.
2. Push < NT R> and then AUTO1 mode is started.
3. Push <DOWN> and AUTO2 mode is displayed.
4. Push < NT R> 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.
5. When Auto calibration is done, ‘COMPL T ’ message appears on the LCD.
After 4 seconds the procedure is returned to RUN mode and the valve stroke by
current input signal is displayed as a percentage.
6. Zero, Span, PID parameters and RA/DA are automatically set when AUTO2
calibration is completed. Below: Entire Modes and Functions
Auto Calibration (AUT CAL)
The calibration of the positioner is simply performed by auto calibration. There are
3 types of auto calibration: AUTO1, AUTO2 and AUTO3.
AUTO1 calibration is useful for users in the field. AUTO2 calibration is for valve
companies or the initial parameter setting for the positioner.
It takes about 2-3 minutes for Auto calibration and it can be different based on the
actuator's volume. AUTO2 and AUTO3 calibration set the RA/DA automatically.
Auto Calibration Types
Auto 1 Calibration (AUT 1)
In this mode, all parameters necessary for valve operation are set except KP, KI,
KD and RA/DA. It is used to re-execute calibration by users in the field after being
supplied the positioner unit, whose parameters were set by the valve company.
1. Push < NT R> for 6 seconds in RUN mode and AUTO CAL message should
appear.
2. Push < NT R> and then AUTO1 mode is displayed.
3. Push < NT R> again at AUTO1 mode and Auto 1 calibration is started.
4. When Auto 1 calibration is done, ‘COMPL T ’ message appears on the LCD.
After 4 seconds the procedure returns to RUN mode and the valve stroke by
current input signal is displayed as a percentage.
Auto 2 Calibration (AUT 2)
All parameters necessary to operate valve are set. This calibration is used when
the positioner is first installed with valve. Refer back to First Auto Calibration.
Auto 3 Calibration (AUT 3)
All parameters necessary to operate 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 < NT R> 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 < NT R> at RUN mode until AUTO CAL message is displayed.
2. Push <DOWN> and MANUAL mode is displayed.
3. Push < NT R> again. Two lines appear on the LCD. The upper line indicates
valve stroke by percentage, and the lower line indicates absolute value of inner
resistance of the positioner. “MA” means that manual mode is in operation.
4. Push <UP> or <DOWN> and the valve stem moves up or down. Regardless of
RA/DA, if <UP> is pushed, the valve stem moves up (in case of linear valve). If
<DOWN> is pushed, the valve stem moves down. In order to make the valve
stem move fast, push < NT R> with <UP>, or <DOWN>.
5. Push < SC> and MANUAL mode is displayed.

Since this makes the valve or actuator move, before auto
calibration, the valve must be separated from the entire
system.
CAUTI N
When the positioner is installed on the valve in the field after
setting, we recommend using AUTO1 calibration rather than
AUTO2 calibration. This is because the valve company sets optimum parameters
so it is better that those registered parameters are not changed by AUTO1
calibration.
CAUTI N

Parameter Mode (PARAM)
Parameter Types
There are four types in parameter mode: Dead Zone, KP, KI, and KD.
These values are reflected as soon as they are changed, therefore the
appropriate values are found by checking the valve’s motion in real time.
Dead Zone (dEAdZ NE)
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.
KP
This is a proportion constant value that is correction by error %. If this value is too
big, there can be hunting, even though it finds position by the input signal. If the
value is too small, accuracy gets worse.
KI
This is an integral constant value adding or subtracting the correction that is
corrected error % on the previous correction signal. If this value is too big, there
can be oscillation. If it is too small, the time to find the exact position increases.
KD
This is a differential constant value adding the previous correction signal with the
changing correction signal by the error % change rate.

Valve Mode
This mode adjusts the various characteristics.
Action Type (ACT)
It can be set to Direct Action (DA) or Reverse Action (RA).
Characteristics (CHAR)
Set Characteristics. There are three types of valve characteristics: Linear (LIN),
Q% ( Q), and Quick Open (QO). The following is the example of the three
characteristic curves.
User Characteristics (USER SET)
When a specific characteristic is needed but not included in the above
characteristics, the user can make a specific characteristic curve by choosing 16
points voluntarily according to the field conditions the user’s need.
Tight Shut pen (TSHUT P)
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 < NT R> at RUN mode for six seconds and then AUTO CAL mode is
displayed. Push <DOWN> four times to go into VALV mode.
2. Push < NT R> and ACT RA (in case of RA) is displayed.
3. Push < NT R> again, then *ACT RA is displayed.
4. Adjust to *ACT DA by pushing <UP> or <DOWN> and save it with < NT R>.
+ACT DA message appears.
5. Push < SC> three times to return to RUN mode.
Adjustment of Characteristics (CHAR)
1. Push < NT R> at VALV mode and then push <DOWN>. CHAR LIN (in case
of linear characteristics) mode is displayed.
2. Push < NT R>. *HAR LIN mode is displayed and characteristics can be
adjusted at the mode.
3. Adjust Characteristics (ex: Q) by pushing <UP> or <DOWN> and save it with
< NT R>. + HAR Q is displayed.

Adjustment of User Characteristics (USER SET)
1. Push < NT R> at VALV mode and ACT RA or ACT DA is displayed.
2. Push <DOWN> twice, then US R S T mode is started.
3. Push < NT R>. *PO S T 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>.
5. Save it with < NT R>. While P0 value is being saved, *P1 S T mode is
displayed.
6. *P1 S T mode is used to adjust the second point characteristic in 16 points.
Adjustment method is the same as P0* S T mode.
7. Save the valve stroke percentage from P2 to P15 S T mode; save it with
< NT R>.
8. After adjustment of valve stroke percentage at *P15 S T mode, save it with
< NT R>.

Adjustment of Tight Shut pen (TSHUT P)
1. Push < nter > at VALV mode and ACT RA or ACT DA is displayed. Push
<DOWN> three times at this mode. TSHUT OP is displayed.
2. Push < NT R>. *SHUT OP mode is displayed and in this mode users can set
stroke at the time of Tight Open. Initial setting is done as 100%, which means
cancellation of this function. Adjust the value (ex: 95.0%) by pushing <UP> or
<DOWN> and save it with < NT R>. +SHUT OP is displayed.
3. Push < SC> three times to return to RUN mode.
Adjustment of Tight Shut Close (T SHUT CL)
1. Push < NT R> at VALV mode and ACT RA or ACT DA is displayed. Push
<DOWN> four times at this mode. TSHUT CL is displayed.
2. Push < NT R>. *SHUT CL mode is displayed and in this mode users can set
stroke at the time of tight close. Initial setting is done as 0.3%. 0% means
cancellation of this function. Adjust the value (ex: .5%) by pushing <UP> or
<DOWN> and save it by pushing < NT R>. +SHUT CL is displayed.
3. Push < SC> three times to return to RUN mode.
Adjustment of Split Range (SPLIT)
1. Push < NT R> at VALV mode and ACT RA or ACT DA is displayed.
2. Push <DOWN> five times and SPLIT mode is displayed. The numbers on the
LCD are the range of current signal input to the positioner. 4 to 20 mA current
signal is set as the standard.
3. Push < NT R>. *SPLIT mode is displayed and input signal range can be
adjusted. Adjust input signal range with <UP> or <DOWN> and save it with
< NT R>.
4. +SPLIT mode is displayed while saving adjusted range. Push < SC> three
times to return to RUN mode.
VIEW Mode
This mode provides users with various information about the Series 185 and 285
positioners. In this mode, users can change the valve stroke types displayed on
LCD to % or numbers. Refer to the next table for information and description
displayed on VI W mode.
1. Push <DOWN> at AUTO CAL mode and VI W mode is displayed.
2. Push < NT R> at VI W mode, then information mode is started.
3. Check information by using <UP> or <DOWN> and push < SC>.
4. Push < SC> again to return to RUN mode.
