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. eedback lever and lever spring
3. lange nut (attached on the bottom of main shaft of Series 185 body)
4. our hexagon head bolts M8x1.25P
5. our 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.
- eedback 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.
NOTE: 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
ork lever and lever spring to attach on actuator

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.
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˝ (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. or 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. ix 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.

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:
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.
First Auto Calibration
irst 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.
Notice: 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 AUTO 2 calibration parameters have been factory set to the optimum
settings.
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.
RA/DA
Direct acting (DA) or Reverse acting (RA).
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. Press and hold <ENTER> for 6 seconds in RUN mode and AUTO CAL
message should appear.
2. Push <ENTER> and AUTO CAL menu is displayed.
3. Push <ENTER> at AUTO1 mode and Auto 1 calibration is started.
4. When Auto 1 calibration is done, ‘COMPLETE’ message will appear on the
LCD. After 4 seconds the procedure returns to RUN mode.
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 irst Auto Calibration.
1. Press and hold <ENTER> for 6 seconds in RUN mode and AUTO CAL
message should appear.
2. Push <ENTER> and AUTO CAL menu is displayed.
3. Push <DOWN> at AUTO CAL and select AUTO 2.
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. Duration may vary based on actuators
volume.
5. When Auto calibration is done, ‘COMPLETE’ message appears on the LCD.
After 4 seconds the procedure is returned to RUN mode. Zero, Span, PID
parameters and RA/DA are automatically set when Auto 2 calibration is
completed. Below: Entire Modes and Functions
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. Press and hold <ENTER> for 6 seconds in RUN mode and AUTO CAL
message should appear.
2. Push <ENTER> and AUTO CAL menu is displayed.
3. Push <DOWN> at AUTO CAL and select AUTO 3.
4. Push <ENTER> and AUTO3 calibration is started.
5. When Auto calibration is done, ‘COMPLETE’ message appears on the LCD.
After 4 seconds the procedure is returned to RUN mode.
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. Press and hold <ENTER> for 6 seconds in RUN mode until AUTO CAL
message is displayed.
2. Scroll with <DOWN> button until MANUAL mode is displayed.
3. Push <ENTER> to enter MANUAL mode. 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 valve stem moves up or down. Regardless of
RA/DA, if <UP> is pushed, valve stem moves up (in case of linear valve). If
<DOWN> is pushed, valve stem moves down. To make the valve stem move
fast, push <ENTER> with <UP>, or <DOWN>.
5. Push <ESC> to exit MANUAL mode.
