Installation and adjusting

1 Installation environment requirements

1)This product is not exploslon-proof. Do no tuselt in the environment with flammable gasor corroslivegas.

2)Installed in a water flooded and outdoor please explain in advance

3)Please reserve wiring, maintenance space such as for manual operation.

4)In order to avoid the rain, direct sunlight, need to install the protection cover, or chooses IP67 protection level.

5)Basic installation direction to keep the window to the top, the vertical pipeline actuators installation, cable interface to the ground.

2 Ambient temperature, medium temperature

1)The ambient temperature is in the range of -30℃~60℃ .

2)When the ambient temperatureis below zero, install a dehumidifler in the machine.

3)When the working medium is high temperature, the bracket connected with the valve plays a role in reducing heat conduction.

4)When the working medium temperature is below 60℃, please choose standard support.

5)When the working medium temperature is above 60℃, please choose high temperature bracket.

3 Valve connection

1)Manually turn the valve, confimthat there is no abnormal situation, and tum to the fully closed position,and fix the support on the valve.

2)Place the electricactuator on the support and screwiton gently with bolts and nuts.

3)Turn the electric actuator to the closed position, and fix the valve core shaft and the electric actuator output shaft with the coupling and screw.

4)Use the handle to turn the electric actuator, the movement is smooth, becareful not to cross the set limit switch limit.

Note:
When installing, make sure that the switch of the actuator is conslstent with the switch of the valve. The flange at the bottom of the actuator meets the IS05211 standard, and if the valve connected to it also meets this standard.

It can beeasily connected; If this standard is not met, an additional bracket connection is required.

4 Adjustment

1)Adjustment of Stroke limit

Turm the handwheel to move the actuator to the position where the valve is fully closed. Then, loosen the limit CAM tightening nut with a wrench, tum the limit CAM (yellow open, red close)to adjust it to just press the lower limit switch, and hear the 'click' sound for 2 times and then tighten the limit CAM, adjust the full close position, and set the full open position in the same way. (As shown in Figure 14)

2)Adjustment of mechanical limit

Loosen nut mechanical limit and then make sure the actuator move to the full-closed position. Rotate limiting nuts, then stop rotate when it comes across the fan-shaped gear inside and then screw out two circles and screw the nuts at last.(Showm in Figure 15)

3)Adjustment of potentiometer

Potentiometer is output as a feedback signal in the actuator, with three output pins, the middle pin is the output, and the left and right sides are the power supply (note: the resistor should not have a reslstance value of zero and jump phenomenon). Use the handle to turn the valve to the fully open position. Use a multimeter to measure the operation of the limit switch. Adjust the pin resistance on the terminal to the range of 35Ω-60Ω. If it is not correct, it can be adjusted by turning the potentiometer transmission gear.(As shown in Figure 16)

5 Test Operation

1)Manual Operation

Cut power off before making manual operation. Insert the manual handle into the hexagonal hole undemeath the rubber cap.

Note: Opening to Full-open and full-closed position, after the limit switch turns half circle, it will come acros mechanical block. If rotate excessively, it would resul the amage of other parts, so it should be awided excessive force.

2)Power operation

Before making power operation:

*Confirm that the indication on the position meter and the valve opening are matching each other.

*Confirm that the circuits are properly wired, also that the unit operates in correct direction with external switches.

1)Check the wiring diagram, power supply, input/output signal correctly.

2)Don't change the internal wiring.

3]please check the rotating direction if the power supply is three-phase.

4)Make sure the actuator be in the on/off position, turn on the power and input the open slgnal.
5)If the actuator runs to the open direction, it means the wiring is correct.

6)If not, it must be changed 2 wiring lines of the 3 wiring line.

6 Maintenance & lubrication

1)The product uses special molybdenum base grease, so there is no need to add oil;

2)Regular rotation: When the valve does no work foralong time, the machine can be driven regularly to check for abnormalities;

3)For control type (with field control) structions, please refer to the actuator control module manual (technical document attachment).
