3. Installation
3.1 Safety
When installing a unit, please ensure to read and follow safety instructions.
Check unit’s specification and ensure to use as specified.
Follow other explosion proof procedures and safety precautions.
Use bypass valve or other supportive equipment to avoid entire system “shut down”.
Make sure all input and supply pressure to valve, actuator, and other related devices
must be turned off.
3.2 SPTM-5VL Installation
1. Proper bracket must be made in order to adapt SPTM-5V on the actuator yoke.
Please consider following important points when a bracket is being designed.
-
-
SPTM-5V feedback lever must be parallel to the ground at 50% of the valve stroke.
Feedback lever connection with the pin of the actuator clamp should be installed in
such a way that the valve stroke length coincides with the corresponding figure of
“mm marked on the feedback lever. Improper setting may cause poor linearity.
2. Assemble the SPTM-5V with the bracket made in previous
step by fastening the bolts. Please refer to the backside of
the SPTM-5V for size of the bolts. The standard bolt size is
M8 x 1.25P.
3. Attach SPTM-5V with the bracket to the actuator yoke – DO
NOT TIGHTEN COMPLETELY.
4. Connect SPTM-5V’s feedback lever to the actuator clamp. The hole gap on the
feedback lever is 6.5mm. The connection pins outer diameter should be less than
6.3mm.
5. Connect supply pressure to the actuator temporarily. Supply enough supply pressure to
the actuator in order to position the actuator clamp at 50% of the total valve stroke.
8
SPTM-5V series
6. Insert connection pin into the feedback lever. The pin should be inserted when the
actuator clamp is at 50% of the total valve stroke.
7. Check if the feedback lever is parallel to the ground at 50% of the
valve stroke. If it is not parallel, adjust the bracket or feedback link
bar to make parallel. Improper installation may cause poor
linearity.
8. Check the valve stroke. The stroke marks are indicated on the feedback lever.
Position the connection pin at the number on the feedback lever which corresponds to
the desired valve stroke. To adjust, mover the bracket or the connection pin or both.
9. After installing the SPTM-5v, operate the valve from 0% to
100% stroke by using direct air to the actuator. On both 0%
and 100%, the feedback lever should not touch the lever
stopper, which is located on the backside of SPTM-5V. If the
feedback lever touches the stopper, SPTM-5V should be
installed further away from the yoke.
3.3 SPTM-5VR Installation
1. Please refer to SPTM-5VL installation section for important note for bracket design.
2. There are two types of the lever – standard and NAMUR type.

SPTM-5V series
4. Connection – Power
4.1 Safety
When installing a unit, please ensure to read and follow safety instructions.
When installing in hazardous and explosive gas area, conduit tube or pressure-proof
packing union must be used.
Please use ring-type rug to protect against vibration or any other external impact.
Please use twisted cable with conductor section are 1.25mm
2
and that is suitable for
600V (complying to 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 equipments, such as high-capacity
transformer or motor.

5. Adjustment
5.1 Setting Point Switch
SPTM-5V series can be calibrated in 2 or 5 points setting.
a) 2 Point Setting:
By setting minimum and maximum points <0% and 100% of valve stroke>, in-b
b) 5 Point Setting
By setting 5 points <0%, 25%, 50%, 75%, and 100%> the outputs can be set accordingly.
5.2 Adjustment - Calibration
a) Input 4mA signal to the positioner to move the valve stroke to the 4mA position.
b) After the valve reaches at the 4mA position, press “4mA button for 3-4 seconds. The
lamp will be lighted, and this indicates that 4mA output
feedback position has been calibrated.
c) Please repeat above step for 8mA, 12mA, 16mA, and
20mA for 5 point setting. For 2 point setting, repeat
above step for 20mA only.
5.3 Adjustment – Potentiometer
Potentiometer is designed to output 12mA signal when the feedback lever is at 50% position.
In case of dislocation of the potentiometer, please follow below procedure to re-set the
potentiometer.
Power must be turned off before adjusting potentiometer.
Please be cautious when adjusting potentiometer.
Please make sure that there is no remaining circuit on the PCB.
Please do not use excessive force when disconnecting potentiometer from the PCB.
1. Locate the potentiometer under the PCB. Disconnect from the PCB. Please do not use
excessive force.
2. Unfasten lock screw which locks the potentiometer gear and take out potentiometer body
from the lag-gear.
3. Fix the feedback lever at 50% position and measure resistance level by connecting two
probes out of three inlets.
4. Rotate pinion gear until resistance vale is about 5KΩ.
5. After setting the resistance value, rotate stopper to the normal position an fasten the lock
screw.
6. Reconnect potentiometer to the PCB and reinstall PCB onto SPTM-5V body.

SPTM-5VR
6. Troubleshooting
1) SPTM-5V shows no output signal.
A. Check actual input signal to SPTM-5V.
B. Check power connection and + / - poles.
2) Input signal value to the positioner and output signal value from SPTM-5V differs
dramatically.
A. Check input signal value and supply voltage. Insufficient voltage can affect input signal
value.
B. Check the installation of the positioner. If the positioner is installed improperly, please
refer to the positioner’s manual and re-install the positioner.
C. Set the positioner’s zero and span. Inaccurate zero and span setting can lower the
accuracy and linearity.
D. Check the installation of the position transmitter. If SPTM-5V is installed improperly,
then refer to the manual and re-install.
3) Sudden changes in SPTM-5V’s output signal value.
A. Please make sure that SPTM-5V’s lever is placed at 50% point. If not, SPTM-5V
needs to be re-installed and adjusted to be placed at the 50% point.
B. Adjust the potentiometer. Potentiometer’s load resistance is 10KΩ, and it should be
ready at the 50% point.
