Installation and adjusting
1 Installation environment requirements
- This product is not explosion-proof. Do no tuselt in the environment with flammable gasor corrosivegas.
- Installed in a water flooded and outdoor please explain in advance.
- Please reserve wiring, maintenance space such as for manual operation.
- In order to avoid the rain, direct sunlight, need to install the protection cover, or chooses IP67 protection level.
- 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
- The ambient temperature is in the range of -30℃~60℃ .
- When the ambient temperatureis below zero, install a dehumidifler in the machine.
- When the working medium is high temperature, the bracket connected with the valve plays a role in reducing heat conduction.
- When the working medium temperature is below 60℃, please choose standard support.
- When the working medium temperature is above 60℃, please choose high temperature bracket.
3 Valve connection
- Manually turn the valve, confirm that there is no abnormal situation, and turn to the fully closed position, and fix the support on the valve.
- Place the electric actuator on the support and screw it on gently with bolts and nuts.
- 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.
- Use the handle to turn the electric actuator, the movement is smooth, be careful not to cross the set limit switch limit.
Note: When installing, make sure that the switch of the actuator is consistent with the switch of the valve. The flange at the bottom of the actuator meets the ISO5211 standard, and if the valve connected to it also meets this standard, it can be easily connected; If this standard is not met, an additional bracket connection is required.
4 Adjustment
1) Adjustment of Stroke limit
Turn 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, turn 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)
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. (Shown 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 resistance 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 underneath the rubber cap.
Note: Opening to Full-open and full-closed position, after the limit switch turns half circle, it will come across mechanical block. If rotate excessively, it would result the damage of other parts, so it should be avoided 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.
- Check the wiring diagram, power supply, input/output signal correctly.
- Don't change the internal wiring.
- Please check the rotating direction if the power supply is three-phase.
- Make sure the actuator be in the on/off position, turn on the power and input the open signal.
- If the actuator runs to the open direction, it means the wiring is correct.
- If not, it must be changed 2 wiring lines of the 3 wiring line.
6 Maintenance & lubrication
- The product uses special molybdenum base grease, so there is no need to add oil;
- Regular rotation: When the valve does no work for a long time, the machine can be driven regularly to check for abnormalities;
- For control type (with field control) instructions, please refer to the actuator control module manual (technical document attachment).
Frequently Asked Questions (FAQ)
What is the primary application of the BN series electric actuator?
The BN series electric actuator is designed to control 0-270° rotary valves, including butterfly valves, ball valves, throttles, baffle valves, and plug valves. It is widely used in industries such as petroleum, chemical, water treatment, shipping, paper, power stations, heating supply, and building automation.
What protection class does the BN electric actuator housing offer?
The standard product is made of aluminum alloy with a polyester powder coating and offers an IP66 protection class, which provides strong corrosion resistance. An optional IP67 protection class is also available.
Can the BN series actuator be operated manually?
Yes, it features a safe and reliable handle design for easy manual operation. Always ensure the power supply is turned "OFF" before attempting manual operation, and avoid excessive force to prevent damage to the internal parts.
What is the purpose of the built-in dryer in the actuator?
The dryer is used to regulate the internal temperature and prevent moisture condensation inside the actuator caused by weather or temperature changes. This keeps the electrical elements dry and reliable.
Does the actuator require external lubrication during maintenance?
No, the actuator is lubricated with a special molybdenum base grease during manufacturing, which eliminates the need to add oil or grease during standard maintenance.
