Electrical wiring diagram
 

NOTE-1
       Figure 1 and Figure 2 above show wiring diagram of the mode knob in the REMOTE position. The local OPEN/CLOSE/CAL button is invalid. Figure 1 is the 24VDC using the actuator. Figure 2 shows the 24VDC outside the actuator.

NOTE-2
       When the IN-STOP distal normally closed button is open (pressed), it is in LATCH mode. Press and hold OPEN or CLOSE to control the valve action.

NOTE-3
       THREE mode when the IN-STOP distal normally closed button is closed (not pressed)
       The THREE mode divides the OPEN and CLOSE action processes into three intervals, and each of the three sections sets the speed, which can play the role of mitigating impact and waterproof hammer.
       The interval setting, the motion speed, and the stop time are all set in the user menu ten.
       Click the OPEN button. The actuator will always run to the F/O state.
       Pressing the CLOSE button will cause the actuator to run to the F/C state.
       When the STOP button is pressed during operation, the actuator stops running.

NOTE-4
       SEL switch for selecting digital control (DI) or analog control (AI)
       In AI mode, the actuator inputs a 4-20 mA analog signal according to the Al terminal {corresponds to 0-100% of the stroke). Drive the valve to the appropriate position at the set speed.
       In the Al mode. Press the remote STOP button or press the local STOP button or toggle the actuator to stop the action and issue a forced stop alarm message.
       The opening feedback signal is 4-20 mA corresponding to 0-100% of the stroke.

NOTE-5
       The EMG signal is a chain signal access terminal, which only works in the REMOTE state, and the EMG signal is a continuous signal. When the EMG signal is valid, the actuator performs valve opening or closing according to the set requirements, and is used as a chain control.
