Explosion-proof realization
GB3836 series standards specify different types of explosion-proof types and related design, manufacturing, inspection and testing standards.
The explosion-proof type of BNE serie selectric actuator mechanism is “flame proof type” (Exd).
(1)Flame proof type (Exd)
The actuator allows an explosion to occur inside the equipment, and the flameproof surface of the shell is designed to prevent the internal sparkor the explosion carrier from contacting the outside world.The suitable flameproof surface clearance and sufficient length of the flameproof surface ensure product safety. At the sametime, the strong shell can with stand the high pressure generated by the internal explosion without being damaged. BNE explosion-proof series actuator in the motor cavity, electrical component cavityand Designed and manufactured according to the flameproof standard of the line cavity.
(2)explosion-proof rating

Installation and adjusting
1 .Installation environment requirements
1)The types or categories of explosve media around the places of the devices must bein conformity to the explosion-proof regulation of this product.
2)Installed inawater flooded and outdoor please explaln inadvance.
3)Please reserve wiring,main tenance space such as form anual operation.
4)In order toavoidthe 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,thevertical 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 amblent temperature is below zero,install adehumidifier in the machine.
3)When the working mediumis hight emperature,the bracket connected with the valve plays arole in reducing heat conduction.
4)When the working medium temperature is below 60*C, please choose standard support.
5)When the working medium temperature is above 60℃, please choose high temperature bracket.
3 .Valve connection
1)Manuallytum the valve,confirm that there is no abnormal situation, and turn to the fully closed position,and fixthe support
on the valve.
2)Place the electric actuatoron the suppor tand screwiton gently with bolts and nuts.
3)Turn the electricactuator to the closed position,and fixth evalve core shaft and the electric actuator output shaft with the coupling and screw.
4)Use the handle to turm 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 IS0 5211 standard, and ifthevalve connected toital so meets this standard. It can be easily connected; If this standard is not met, anadditional 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 awrench,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 shownin Figure 12)
2)Adjustment of mechanical limit
Loosen nut mechanical limit and then make suretheactuatormoveto 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 Figure13)
3）Adjustment of potentiometer
Potentiometer is output asa feedback signal in the actuator,with three output pins,the middle pinis 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 limilt switch. Adjust the pin resistance on the terminal to the range of 350-600.If it is not correct,it can be adjusted by turning the potentiometer trans mission gear,(As shown in Figure 14)
5 .TestOperation
1)Manual Operation
Cut power off be fore making manual operation.Insert the manual handle into the hexagonal hole under meaththe rubber cap.
Note:Opening to Full open andfull-closed position,after the limit switch turn shalfdrcle,it will come across mechanical block.If rotate excessively,it would result the damage of other parts,solt should be awolded excessve force.
2)Power operation
Before making power operation:
Confirm that the indication on the position meterand the valve opening are matching each other
Confirm that the circuits are properly wired,also that the unit operates incorrect direction with external switches.
1)Check the wiringdiagram,power supply,input/output signal correctly.
2)Don’t change the internal wiring
3)Please check therotatingdirection if the power supply is three-phase.
4)Make sure the actuator bein the on/off position,turm on the power and input the open signa
5)If the actuator runs to the open direction,it means the wiringis correct.
5)If the actuator runs to the open direction,it means the wiringis 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 doesno work for alongtime,the machine can bedriven regularly to checkfo abnorm alities;
3)For control type (with field control)structions,please refer to the actuator control module manual (technical document attachment)
3)For control type (with field control)structions,please refer to the actuator control module manual (technical document attachment)
Confirm the Right BNE Series Electric Actuator
Send the valve type, size and torque, the air supply or voltage, and whether it should fail open, fail close or stay in place. The quotation is confirmed against that duty.
