Table printing machine control circuit

①Close the air switch and ferromagnetic regulator switch, turn on the key switch to send power to the electrical frame, and press the main power switch SA1 to make the AC contactor KM
electrically closed, as shown in Figure 7140. At the same time, the signal is connected in series The auxiliary contact KM in the same circuit is closed and the indicator light is on.
    ② Press the button ISA1, the KM1 coil is closed, and the main contact of KM1 connected in the main circuit of the DC motor in the picture is also closed, then the main
drive DC motor works, drives the cloth machine forward, and the signal assists The KM1 auxiliary contact in circuit 11-22 is connected and the indicator
light is on.
    2) Automatic: Turn on the main power switch, press SA, and drive the express train, and a series of actions will be automatically controlled by programmed procedures.
That is, fast train, fast train, slow train, slow train, lift, net train, forward, reverse scraping, scraping and express train, and continue to work like this over and over again.
