T80°C/T90°C Db)
code . It can be used in Zone 1,2 area.
* In danger area which is exiting explosive gas, explosion proof type of cables or
flame explosion proof packing type cable must be used. In case of using explosive
proof cable ,it must be used by gasket and sealed completely.
* When the power is connected, make sure that do not open SP760 power terminal box .
Before opening terminal box, make sure that power is off completely and after erasing
current and voltage completely, it must be opened.
* SP760 series positioner have 2 ports for power connection. If one side of connection
must be used when using explosive cable or flame explosion proof to packing plug
in the other side should be used explosive blind plug in order to protect.(In case that
the other items shall be required to use except our company's supplying plug blind
approved resistance to explosion proof type structure shieling fitting or flame explosion
proof type cable gland must be used when connecting power on.)
* Ring terminal with surface area of more that 0.195 mm2 with should be used
,and also M4 spring washer should be used to prevent failing out.
* For external ground terminal, ring terminal with surface area of more than 5.5 m2
should be used .
* There will be risk of explosion due to electro-static charge. Static electricity charge
may develop when cleaning the products with a dry cloth. It is imperative to avoid
static electricity charge in the hazard area. If cleaning the surface of the products is
required, please use wet clothes.

2-8 Principle of Operation
Once Control PCB(3) receives an input signal (4~20mA), the input current is delivered
to coil(6) of Torque Motor(1) from which magnetic force is generated in core(7) and
the force and polarity difference with a permanent magnet moves nozzle flapper(9) by
which nozzle(8) and nozzle flapper(9) are far isolated, lowering the pressure of nozzle
pressure chamber and finally generating the difference of pressure with the pressure
chamber(14).Therefore, spool(31) pushes poppetA(12), opening port A : OUT 1 output

is connected to lower cylinder(28) while upper cylinder is connected to exhaust pipe
raising piston rod(30) Lever(29) delivers a motion to output shaft (5) operating Pinion
(23) and Gear(24) and rotating potentiometer(22) from which the resistance is fed back
to control PCB(3). The feedback value is compared to the input value and calculated
accordingly; if any difference is found, a changed input current is delivered to coil (6)
of Torque motor(1) so to be properly located while repeating till it is balanced. On the
contrary, if input current is lower,Nozzle Flapper(9) block Nozzel (8) so that the pressure
in the nozzle pressure chamber(15) rises, spool (31) pushes poppet B (13) according to
the difference of pressure, opening port B while OUT 2 output is connected to upper
cylinder(27) and the lower cylinder(28) is connected to exhaust pipe, lowering piston rod
(30).Likewise, lever(29) delivers a motion to shaft(5),operating pinion(23) and gear(24),

3. Installation
3-1 Caution before installation
* When installing or replacing positioner equipped in actuator, please follow safety
instructions.
- Any input or supply pressure to valve, actuator and /or to other related devices
must be turned off.
- Separate by-pass valve or other device from control valve so that total system
may not be shut down.
- Make sure that there is no remaining pressure in actuator.
- Install filter regulator in positioner air supply line so that air pressure may be
maintained properly and different material may not be inserted.
- Be alert that supplying air may not be mixed with oil, water and different material.
- When installing positioner, safety work is required after input signal and air
pressure are shut down.
3-2 Tools for Installation
- Hex Wrench set
- (+) & (-) screw drivers
- Spanners for hexagonal-head bolts
3-3 Linear Positioner Installation
Linear positioner shall be installed and used on linear motion valves such as glove
or gate vale type which uses spring return type diaphragm or piston actuators.
3-3-1 Caution on installation
- When fabricating bracket and connecting to connection bar ,following 2 kind of
contents must be regulated.
- If following condition shall not be kept during the installation,
it may be affected the performance of the products such as linearity function.
Caution
▶ When the valve opening is 50% ,the feedback lever should be horizontal.
▶ When valve opening is 50%, the stem connection pin should be located
at the numeric position marked on the feedback lever that is corresponding
to the valve stroke.
