Connect the red and black wires to the power cord, turn off the run button, press the SET button twice, AL (lower limit pressure) will appear, press the upper button to adjust the lower limit start value,

Press SET again, AH (upper limit pressure) will appear, press the upper key to adjust the upper limit stop value,

Press SET again, SAVE (data saving) appears,

Press SET again to return to the measurement interface,

Click to run, you can use it.

For example: 0.5Mpa start 0.8mpa stop

AL is set to 0.5mpa, AH is set to 0.8mpa, the contact between yellow and blue is normally open, and the pressure is within the setting range.

IV. Precautions

1. The incoming power supply of the experimental device should be correctly connected, and the grounding should be good and reliable.
2. When using, keep your hands dry and clean, and pay attention not to scratch the surface of the equipment with sharp objects.
3. During the experiment, after the wiring is correctly connected, the instructor should confirm that it is correct before energizing the experiment. It is strictly forbidden to touch the live parts with your hands or conductive objects, and you will be responsible for the electric shock in violation of regulations.
4. After using the experimental device, turn off the main power switch and unplug the power plug from the socket.
5. When the cylinder and conveyor belt are working, it is strictly forbidden to touch the cylinder push rod and the motor rotating shaft with your hands to avoid accidental injury.
6. When encountering an emergency, disconnect the system power supply or turn off the main power switch of the control box in time.
