parameter setting
Quarter-turn actuator adjustable ratio of the signal gear unit
1. Local operation
Local operation includes the following contents: see picture 4-1 Operation Faceplate Diagram
Terminal(standard )
standard(Metric)
information center
operation button
LED light
1 information center
LCD screen provides the actuator’s information of operation mode, position, parameter setting choices, parameter input, information feedback and alarm information.
2 operation buttons
You can choose the control operation sites of actuator (local/remote) via the operation buttons, and running the actuator locally at the same time. There are four buttons provide different functions (see table 4-1).
3 LED Light
LED blue light blinking indicates the actuator is opening or closing, red light indicates the actuator fails to work properly.
2. remote operation
Remote operating command depends on the parameter switching value and setting of switching value mode, through:
Operate by switching input terminals (on, off, stop and emergency) and analog input channels.
Operate by Profibus DP or modbus RTU manual operate.
Warning: hand shrank (hand wheel) can be connected to the interior worm when the actuator is not operating.
Warning: After debugging, the operating of actuator with hand shrank should be confined to the scope of terminal position set before. Otherwise, the scope has to be reset.
Clockwise rotation of the hand shrank (hand wheel) will lead to:
Clockwise rotation (seen from the side of worm-gear box marked with arrow) of Quarter-Turn actuator when the worm-gear box is RR.
1.Press the handle/handwheel in the direction towards gearbox and overcome the resistance of the spring, then users can switch the motor operation mode to manual opeartion mode.
2. Manual operation is preferential compared to motor operation. Motor operation is possible only when hand shrank is loose.
Installing the Electric Actuator to the Valve
1 Notice: the flange plate of valve and electric actuator should be cleaned thoroughly with greasy dirtying,
wiped off surface oil.
2 Small amount of oil should be applied to the connection part.
3 The electric actuator should be accurately installed to the valve.
4 Bolts should be at least 8.8 in respect of level of performance (spring shims should be used to fixed bolts).
5 Torque of swivel bolt is M8 (23Nm) ; MlO (68Nm) ; M16 (305Nm) ; M20 (500Nm).
Type A output shaft should be first processed. If not, please process according to the following steps:
(1) Locating ring D should be unscrewed from flange plate.
(2)Thread bushing A, needle bearing C and bearing shim B should be taken down together.
(3)Needle bearing C and bearing shim B should be taken down from thread busing A. Then the thread should.
be taped out (check concentricity and beating rate after installation) and cleaned.
(4)Ball bearing greasy should be applied to needle bearing C and bearing shim B and attach them to thread bushing A.
(5)Thread bushing A and the bearing should be inserted into the flange of output shaft.
(6)Screw locating ring D in until it is fixed.
(7)Ball bearing greasy should be applied through zerk with greasy gun until oil runs out of the centering ring.
(8)Then hand shank or hand heel should be used to rotated electric actuator so the thread will move to the drive bolts of the valve.
(9)Finally, the flange mounting surface of electric actuator and that of valve should be fastened by bolt when they are next to each other.
Important : please screw the fixing screw nut to make sure the valve-stem drive nut won’t fall off.
