TROUBLESHOOTING (continued)
Should malfunctions occur, the following procedure should determine where the problem is:
1.Remove label web from the machine.
2.Turn the switches “ON”.
3.Trip the
4.Slide the label web down under the star wheel, or (through the photo electric or clear label sensor) until the star wheel turns up on a point and back down. The drive roll should stop turning. If the L60 is equipped with photoelectric label sensing or a clear label sensor, pass the label through the opening until the motor stops.
Drive Roll does not START, check the following:
1.Is the
2.Is the product sensing switch malfunctioning? Check for make and break of switch; listen for relay operation of electric eye.
3.Is the power module plugged into its receptacle securely? The power module is found on the back of the front panel, inside the machine, and can be seen by removing the top cover.
Drive Roll fails to STOP when star wheel turns over:
1.Remove three screws and pull off star wheel cover (See page 13). Lift up and let down star wheel by hand; if drive roller still turns, remove spring from pin on star wheel arm and pull Star Wheel Pivot Arm Assembly off. Activate the switch by hand. If drive roll still turns, check for make and break with ohmmeter, and replace if necessary.
2.Check quick disconnect connections for proper contact.
3.If Drive Roll stops when the switch is operated by hand, replace the star wheel and adjust the star wheel assembly by loosening the two screws that hold the backing plate and move it to a position where the star wheel will open the switch when it turns on a point. (See page 12 for star wheel adjustment procedures).
If these adjustments fail to correct the problem, reset the power module. This can be accomplished by removing front panel. Make sure that you ground yourself before touching the circuit board. Static electricity can damage the board. Place fingers on each side of circuit board. (DO NOT TOUCH ELECTRICAL COMPONENTS ON BOARD.) Move board side to side and push down to be sure board is seated in contacts on bottom.
