2 Product Description
2.1 General
ECON®series 3300 Smart Valve Positioner accurately controls valve stroke in response to an input
signal of 4-20mA from a process controller. A built-in micro-processor optimizes the positioner’s
performance and provides unique functions such as Auto-Calibration, PID Controlled and HART®
Protocol Communications.
2.2 Main Features and Functions
➢LCD display enables users to monitor the positioner status.
➢Easy operation method of using 4 buttons

➢When unexpected situation like momentary blackout happens, our positioner boot-time only take 0.5
second and this can minimize the travel of valve which consequentially increase the safety of system.
➢Positioner operates normally during sudden changes in supply pressure.
➢Low air consumption level and low voltage use (8.5 V) yield to lower plant operating costs. The
series 3300 is compatible with most of controllers.
➢Variable orifices can be used to minimize the hunting occurrence and optimize operating conditions.
➢Valve system becomes more stable by outputting analog feedback signal. Feedback is greatly
improved by the accuracy and fast response of the series 3300.
➢Different valve characteristics can be adjusted –Linear, Quick Open, Equal Percentage, and Custom
which user can make 5 or 18 points characterizations.
➢Tight Shut –Close and Shut - Open can be set.
➢PID parameters can be adjusted in the field without any additional communicator.
➢A/M switch can be used to direct supply air to the actuator or to manually operate the positioner or
valve.
➢Split range 4-12mA or 12-20mA can be set.
➢Operating temperature is -30 ~ 85’C.
➢Manual Operation allows the user to operate the valve manually.
➢It has IP66 ingress protection grade.
➢Epoxy polyester powder coating resists the corrosion process.
➢Maintenance of the positioner is easy because of modularized inner structure.
➢SIL2 certified.

3 Installation
3.1 Safety
When installing a positioner, please ensure to read and follow safety instructions.
➢Any input or supply pressure to valve, actuator, and / or to other related devices must be turned off.
➢Use bypass valve or other supportive equipment to avoid entire system “shut down”.
➢Ensure there is no remaining pressure in the actuator.
➢The positioner has a vent cover to exhaust internal air and drain internal condensation water. When
installing the positioner, make sure the vent cover must be facing downward. Otherwise, the
condensation water could cause damage to PCB
3.2 Figure 3301 and 3302 Installation

3.2.1 Installation Steps
1. A correct bracket must be used in order to mount the positioner on the actuator yoke. Please
consider following important points when a custom bracket is being designed.
➢Positioner’s feedback lever must be parallel to the ground at 50% of the valve stroke.
2. Feedback lever connection with the coupling of the actuator should be installed in such a way that
the valve stroke length coincides with the corresponding Figure in “mm”marked on the feedback
lever. Improper setting may cause poor linearity and may create unnecessary hunting during
operation.
Assemble the positioner with the bracket supplied by fastening the bolts. Please refer to the back of
the positioner for size of the bolts. The standard bolt size is M8.
Figure 3301/3302
3. Check the valve stroke. The stroke marks are indicated on the feedback lever of the positioner.
Position the connection pin at the number on the feedback lever which corresponds to the desired
valve stroke. To adjust, move the bracket, the connection pin or both.
Correct way of Pin Insertion
4. Attach the bar slide assembly with the supplied mounting bolts onto the actuator coupling.
5. Mount the positioner with the bracket and the U-bolts onto the actuator yoke –DO NOT TIGHTEN
POSITIONER COMPLETELY.

Rev.0 –November 1, 2022
15
6. Connect supply pressure through an air-filter regulator 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.
7. Insert the connection pin of the feedback lever in to the bar slide assembly. The pin should be
inserted when the actuator clamp is at 50% of the total valve stroke.
Correct way to connect feedback lever, connection pin, and lever spring
8. Check if 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 and
may create unnecessary hunting during the operation.
9. After installing the positioner, operate the valve from 0% to 100% stroke by using direct air to the
actuator (manual position). On both 0% and 100%, the feedback lever should not touch the lever
stopper, which is located on the back of the positioner. If the feedback lever touches the stopper,
the positioner should be installed further away from the yoke.

Feedback lever should not touch lever stopper 0% ~ 100% valve stroke.
10. After the installation, tighten all of the bolts on the bracket, the feedback lever, and the connection pin.
3.3 Figure 3301 Direct-Mounting Installation
Figure 3301 can be installed on direct-mounting / tube-less type actuators.
3.3.1 Installation Steps
1. Please remove the plug which blocks OUT port on the back of the Figure 3301 unit. OUT ports on the
side of the positioner should be blocked by plugs.
2. Mount Figure 3301 onto actuator’s yoke by using 2 bolts. As you mount the positioner, please be
careful not to lose O-rings from the air channel. Please ensure that the lever adapter connection has
been properly installed onto actuator’s stem before tightly fastened.

(Mounting bolts and washers to actuator, air connections and air hose to be supplied by customer)
3.4.1 Bracket information
The bracket supplied standard with Figure 3303 and 3304 is made out of two components. The bracket
is designed to fit onto the actuator with 20 mm stem height (H). If actuator stem height (H) is 30
mm or 50 mm, the bracket must be adjusted. Please refer to below table how to adjust the bracket.

4.1 Safety
➢Supply pressure should be clean and dry air –avoiding moisture, oil or dust.
➢It is always recommended to use an air filter regulator.
➢The operation of this positioner has only been tested with clean air. For gases other than
clean air please contact ERIKS for suitability.

4.2 Supply Pressure Condition
➢Dry air with dew point at least 10℃lower than ambient temperature.
➢Avoid dusty air. Use 5 micron or smaller filter.
➢Avoid oil.
➢Comply with ISO 8573-1 or ISA 7.0.01.
➢Supply pressure range is 0.14~0.7 MPa (1.4~7 bar)
➢Set air filter regulator’s pressure level 10% higher than actuator’s spring range pressure.
4.3 Piping Condition
➢Ensure inside of pipe is clean of obstructions.
➢Do not use pipeline that is squeezed or shows any type of damages.
➢Pipeline should have more than 6mm of inner diameter (10mm outer diameter) to maintain flow rate.
➢The length of pipeline system should not be extremely long. Longer pipeline system may affect flow
rate due to the friction inside of the pipeline.
4.4 Connection –Actuator
4.4.1 Single acting actuator –Figure 3301 & 3303
Singe acting type positioner is set to use OUT1
port. OUT1 port of positioner should be connected
with the supply pressure port of the actuator when
using spring return actuator of single acting type.
4.4.2 Double acting actuator –Figure 3302 & 3304
Double acting type positioner is set to use OUT1 and
OUT2 port. As input signal increases, the supply
pressure will be supplied through OUT1 port.

the power is still alive.
➢Please use insulated electrical connection ring-type lug to protect against vibration or any other
external impact.
➢Positioner usually uses 4 ~ 20 mA DC. Minimum ampere of input signal of standard type positioner is
3.6 mA (NCS type) PTM internal type is 3.7 mA (NCS type) and HART or HART+PTM internal type is
3.8 mA but maximum ampere of input signal should be 24 mA or under.
➢Compliance voltage of current source must be Min. 10 V and Max. 28 V. If the length of the supply
cable between the current source and the positioner is long, or if there is a filter or safety barrier,
then consider using a current source which could supply higher Compliance voltage.
➢Positioner with PTM options must be supplied with with 9 ~ 28 V DC separately.
➢DO NOT connect Voltage source (9 ~ 28 V DC) to Input (4 ~ 20 mA DC) terminal (IN+, IN-) as it will
cause PCB failure.
➢Positioner should be grounded.
➢Please use twisted cable with conductor section min. 1.25mm2and suitable for 600V (complying to
the conductor table of NEC Article 310.) The outer diameter of the cable should be between 6.35 ~
8 mm. Use shield wire to protect against electro-magnetic field and noise.
➢Please ensure that keep away magnetic materials from a product. It may cause malfunction. For a
magnetic screwdriver, It must be away more than 30 cm from the positioner.
