Setup Screen Settings
Seal Bar
— Temperature setting for L-Sealer sealing heat elements.
Set point — Enter the optimal temperature for sealing and cutting the type of film
you are using.
Actual
— The actual current temperature of the seal bar is displayed in this area.
In addition to the Seal Bar Temperature Setting, there are four timers: a Dwell Timer,
Head Height, Bag Timer, and Film Prefeed Delay Timer.
Explanation of Timers
Dwell Timer
— This is how long the seal head stays together. Keep in mind that the
timer starts as the seal head solenoid activates and the seal head starts moving down.
Bag Timer — This is the length of time after the trailing edge of the product has passed
the photo eye before the seal head comes down. The exit conveyor and power film
unwinds will continue to run until the seal head starts its downward motion.
Film Prefeed Delay Timer
— This is the length of time from when the leading edge of
the product blocks the photo eye until the power film unwinds are activated. Generally:
•
Set this time shorter for lighter packages to get the film rolling before the package
reaches the web of film so the package is not stopped by the stationary film.
•
Set this time longer for heavier packages that possess more momentum.
Some experimentation will be required to arrive at the right Film Prefeed Delay, Bag
Timer, and Head Height setting required to form the right sized bag for each product.
NOTE: The dwell timer must be a larger value than the head height value
to work and seal correctly. Once the seal head comes down and
contacts the lower seal pad, press once more to ensure that your
settings are set.
