Troubleshooting
Machine does not power up when the Power ON button is pressed.
1. Check to make sure all four Emergency Stops are pulled out and operational.
2. Check for a short circuit. Turn off all breakers, and turn the machine back ON. If it comes ON,
switch ON one breaker at a time.
The Input Conveyor belts turn in reverse upon machine startup before the bed is loaded on the
input conveyor.
1. All three bed Alignment Eyes are covered (dark) upon machine startup. Check, and if necessary
adjust the sensitivity screw. The Red led should blink 3 times /sec.
2. If sensitivity is ok but the problem persists, check the dark/light operate mode (white) screw, all
three eyes should be set to light operate (turned clockwise).
3. If the eyes appear to be set correctly but the problem still exists, replace one eye at a time. Make
sure to adjust as the new eye as described above.
The Input Conveyor belts turn in reverse once the bed is loaded and aligned.
1. None of the three size detecting proximity sensors were covered during the alignment phase.
Adjust the proximity sensor in the input and reload the bed. Repeat this procedure until the
problem is solved.
The Input aligns and positions the bed properly and does not continue.
The outfeed eye is full blocked (dark). The Red LED is not on. Adjust the eye sensitivity and
make sure the Eye mode is set to Dark Operate (Counter-clockwise)
1. If problem persists, replace the eye (adjust as described)
The bed transfers to the Output area for sealing; the Cross Seal begins to go down, but goes
back up before cross sealing.
1. The cross seal eye is too sensitive or adjusted too far toward the Input end of the machine. Adjust
the pot on the amplifier to reduce the sensitivity some, but no less than 5 on the scale. If problem
persists, realign the cross seal sensor.
The Side or Cross Seal is spotty in appearance.
1. Check the quality of the Teflon tape on the lower seal bar. Check the silicone rubber tape
backing for cuts.
2. Adjust the Air Cylinder rod ends, out ¼ turn at a time, to lower the seal bar. Test the seal quality
between every adjustment.
The seal is good in appearance but weak.
1. Adjust the seal bar Temperature, and/or dwell time (do not exceed 30).
Machine continues to run even after the film (top or bottom) has run out.
1. Check to make sure that the Film run-out Eye for the corresponding film is set and working
properly.
