3. Principle of operation
Signal current (4 to 20mA) from controller or manual operation device and feedback signal from lift sensor
are respectively converted to digital values and transmitted to control processing part in microprocessor.
Control processing part transmits control signal depending on deviation between the input and the feedback
signal. E-P transformer generates air pressure signal proportional to the control signal. Pilot valve operates
and transmits output air pressure for controlling valve travel depending on air pressure signal.
E-P transformer internally changes magnetic flux of armature in torque motor coil depending on increase anddecrease of control signal. Rotary torque is generated in the armature due to flux change and varies distance
between nozzle and flapper. As a result, air pressure signal proportional to the control signal increases anddecreases, and pilot valve reacts accordingly.

6.3. Quick calibration
Positioner EA10S has a function of quick calibration which can be used in regular maintenance.
This function enables basic calibration of positioner without entering some menu levels.
Procedure for quick calibration is indicated below.
(1) Current generator should be connected to input terminals with input of 12 mA.
(2) <+> button should be pressed continuously after indication of “RUN PV”.
(3) LCD monitor will display countdown as “3”, “2”, “1”.
Button can be released when “STEP1” is displayed, which means start of quick calibration.
(4) LCD monitor will display status in the order of “STEP1”, “FIND V_0”, “STEP2”, “STEP3”, “STEP4”,“GET_BIAS”, “GET_MIN” and “GET_MAX”.
Quick calibration is completed when “COMPLETE” is indicated.
(Display will automatically go back to “RUN PV”)
(5) Next is stroke adjustment.
Current of 20 mA for reverse action actuator and 4 mA for direct action actuator should be input.
(6) <+> or < - > button should be pressed continuously when output air pressure is not enough or too
enough respectively for gaining rated stroke.
(7) Valve will start to move after countdown.
Button should be released when valve reaches to a travel to gain rated stroke.
The above is all of the procedure.
Chapter of “Software configuration” in the next page should be referred for detailed adjustment orcalibration.

Display of “RUN” at left below in the monitor is showing that current status is normal RUN mode, which is
to control valve travel depending on input signal from outside (DC 4 to 20 mA). Display of “PV” at right
below indicates what upper value is. 7 kinds of status indication are available under RUN mode.

6.8. PARAM
Most appropriate control parameters are selected by conducting auto calibration. However, favorable results
might not be gained by auto calibration in some cases such as special actuators or valves with large friction.
In that case, operation can be improved by calibrating PID parameters or dead zone manually.
Type of parameters
There are 4 kinds of parameters; dead zone (DEADZONE), proportional gain (KP), integral constant (KI),differential constant (KD).
Dead zone (DEADZONE)
Dead zone is a band setting (%) where integration control halts to a target value. In such cases that hunting
is occurring due to large friction of gland packing, hunting can be prevented by setting dead zone.
Proportional gain (KP)
Deviation between target value and valve travel can be reduced quickly by increasing proportional gain.
However, increasing the gain too much will lead to hunting.
Integral constant (KI)Time to correct deviation between target value and valve travel can be shortened by increasing integral
constant. However, increasing the constant too much will lead to hunting.
Differential constant (KD)Time to reach target value can be shortened by increasing differential constant. However, increasing theconstant too much will lead to hunting.
“KP_”, “KI_” and “KD_” are parameters to change intensity of each PID parameter while deviation between
target value and valve travel is within 1%. Standard value is 10. For example, if “KP_” parameter is changed
to 12, proportional gain becomes 120% of original parameter setting while deviation between target value andvalve travel is within 1%.
“KI LT” is a parameter to set a time interval in seconds from a state that valve is seated to a beginning of valve
movement. It is not necessary to change the parameter since the parameter is normally set by auto
calibration.

6.9. HAND CAL
Calibration of stroke is automatically completed mostly by conducting auto calibration. Besides, handcalibration is able to be used in case that precise calibration is desired.
Furthermore, hand calibration also enables precise calibration of 4 to 20 mA position transmitter, reversing®

output direction and inversion of position indication in HART communication.
Hand calibration (HAND CAL) includes following items.
PV_ZERO : Position data at 0% point (close) in the valve stroke
PV_END: Position data at 100% point (open) in the valve stroke

TR_ZERO : Data at 0% point (4 mA) for position transmitter
TR_END: Data at 100% point (20 mA) for position transmitterTR: Direction of position transmitter (NORM/REVS)HT: Direction of position indication in HART communication† (NORM/REVS)®

Power source and tester to confirm current are required for data setting of position transmitter.

7.2. Maintenance Procedure
Clogging and dirt of the restriction in the positioner might cause failer. Clean the restriction periodically.
(1) Set supply air pressure at zero.
(2) Loosen the drain cock of the filtered pressure reducing valve. Then, drain and purge properly.
(3) Remove the restriction referring to the figure below.
(4) Clean the restriction by inserting a wire thinner than φ0.2 mm into the restriction.
(5) Apply a coating of silicon grease thinly and uniformly when assembling.
(6) Take reverse procedure when reassembling. Be careful to match the position of φ0.2mm hole of therestriction to the vent hole of gasket.
After checking each part, be sure to checkby performing the operating test and loop
