ABB PPD512 A10-15000 3BHE040375R1023 Static Excitation System Controller

ABB PPD512 A10-15000 3BHE040375R1023 work process: close the control box power switch, open the control box panel on the power switch, in the drawing of the control principle system flowchart, found that the machine’s previous control system there are security risks. Previously, the machine did not run ready to press the button, which is added to my technical reform with the start / stop that is the piano key interlock button control, press the run ready to press the button to prevent the actuator in the manual state of each actuator mistakenly moved, resulting in accidental bodily injury or damage to the machine, you can choose the manual or automatic mode of operation.

ABB PPD512 A10-15000 3BHE040375R1023 choose automatic operation: in the state of the automatic switch is closed, press the start button, slide into the pneumatic solenoid valve for the slide in / slide back cylinder under the action of air pressure to drive the action of the tie rod, so that the moving template sliding forward. When touching the slide-in proximity switch, stop sliding in, then close the mold pneumatic solenoid valve gets power to work, close the mold/open the mold cylinder under the action of air pressure to drive the guide bar action, make the moving template to the top and the fixed template to close quickly.

ABB PPD512 A10-15000 3BHE040375R1023 in the mold sliding into the stage with the mold, once there is an abnormal emergency situation, the safety grating sensing work or step on the foot pedal very stop switch, the mold solenoid valve on the power-off self-reset, the cylinder under the action of gas pressure into the mold opening action, when the mold position reaches the mold limit close switch, slide back solenoid valve When the mold open position reaches the mold open limit switch, the slide back solenoid valve will get the power to work, and the slide in/slide out cylinder will make the moving template slide backward under the action of air pressure to complete the man-machine protection process.
