1. According to the selected model specifications, fix the device according to the diagram, and the grounding terminal on the rear board must be firmly grounded.
2. The circuit diagram numbers of the controller and electric equipment are the same. Connect the controller and electric equipment with the same terminal numbers using cables
Come on, if the user does not need on-site control, terminals 12, 13, and 14 may not be connected. Electric valve operators used in automatic control systems
Terminals 12, 13, and 14 are used as input terminals for signals corresponding to "automatic on" and "automatic off".
3. Press the power button, the power indicator light will light up, the on-site remote control switch will point to the remote control, and the remote control indicator light will light up.
4. Use a handwheel to open the valve to 50% of its opening, press the open or close valve button, and check if the valve's rotation direction matches the button pressed
If there is any inconsistency, immediately press the stop button to cut off the three-phase power supply and replace the arbitrary two phases in the three-phase power supply.
5. Press the open valve button, and when the valve is fully open, the open valve indicator light on the front panel will light up; Press the close valve button, and when the valve is fully closed in place
At this time, the valve closing indicator light on the front panel lights up; When the valve needs to be stopped during the opening or closing process, press the stop button to stop the valve.
Short circuit terminals 4 and 7, and the terminal light on the front panel will light up.
6. When the valve is in the fully open position, adjust the potentiometer on the front panel to show * on the opening gauge.
7. The on-site remote control switch points to the site, and the on-site indicator light is on. There is a short circuit between terminals 12 and 13, and the valve and the open direction are running in a jog mode
State; Short circuit terminals 12 and 14, the valve runs in the closed direction and is in a jog state.
8. Safety tube 5 on the rear panel × 20, 1A.
