What is a wheel limit switch (LS3, LS4, LS5)?

In the Chali JN740 strapping machine, the wire feed wheel system works based on the signal from the limit switches:

• LS3: Heat Press Knife Holding Time Control
• LS4: Newspaper completes 1 strapping cycle
• LS5: Suction coil discharge alarm at the end of the strapping cycle.

These three switches coordinate with the control board to ensure that the belt is fed – tightened – collected in accordance with the technical process.

Signs of a broken wheel limit switch

• The machine does not feed the belt
• The wire is supplied but not retracted
• The machine runs continuously without stopping
• Reporting a mid-cycle interrupt error
• The wheel spins but does not receive a signal

When encountering the above conditions, it is necessary to immediately check the Chali JN740 strapping motorcycle wheel limit switch (LS3, LS4, LS5) to avoid damage to the board or wire feeding motor.
