Seal Time; Reverse; Blow Off; Index Speed - Advanced Poly-Packaging T-1000-S14 Advanced Poly-Bagger Operation Manual

Note: Feed errors are detected and displayed on the screen. See Fig. 3-100. Once a feed error
occurs, the bagger will restart to calculate the bag length.

3.13 Seal Time

Displays, in seconds, the time the pressure (rubber) bar will remain touching the surface of the bag for
proper sealing. Sometimes referred to as "dwell time", seal time is one of three critical components to
obtain a strong seal (other critical factors include seal temperature and seal pressure). To adjust the
Seal Time value, touch the highlighted <Seal Time> menu option to display a number pad. To change
the setting, press the number (decimal point first, if less than 1) and then press <Enter>. To clear an
incorrectly pressed value, press the highlighted <Clear> button and retype the correct value. Pressing
<Enter> will return you to the Bag Setup Screen. Test and further adjust if necessary.

3.14 Reverse

Displays in inches the distance that the rollers will reverse the bag into the T-1000, while the pressure
bar is gripping the bag, to separate the bag being loaded from the bag above. For wider bags, the
reverse distance may need to be increased. A typical setting is between .5" and 1". To adjust the value,
press the <Reverse> button from the Bag Setup Menu. Using the displayed number keypad, press enter
the value followed by the <Enter> button. Press the foot switch or otherwise cycle the bagger to test
the new setting.

3.15 Blow Off

: To decrease the possibility of bags sticking to the Teflon, a blow off tube is
provided as a standard feature. The blower tube is located in the center, immediately below the seal
bar. Typically, the blow off time is set to .1 to .3 seconds.

3.16 Index Speed

Displays in inches per second the speed at which the bag will feed/index into position. For shorter
bags, the speed can be significantly decreased (to 10"/Sec, for instance). For longer bags, the setting
can be increased to the max. setting of 30"/Sec. A typical setting is between 15 and 25" per second. To
adjust the value, press the <IndexSpd> button from the Bag Setup Menu. Using the displayed number
keypad, press enter the value followed by the <Enter> button. Press the foot switch or otherwise cycle
the bagger to test the new setting.

3.17 Seal Temperature

When the power is ON, the heater bar element receives electrical current. The PLC pulses electrical
current to the element until the temperature setting is reached. Shorter pulses indicate maintaining the
temperature. An amber indicator lamp illuminates on the Bag Setup Screen while the element is
receiving current. The longer the light is illuminating, the longer the "pulse" of current and the further
away from the temperature setting. If the temperature of the heater bar is not within a set range around
the set point, "Waiting" will be flashed on the top left screen. To adjust the value, press the highlighted
<Seal Temp> button to display the number keypad popup screen.. Enter the value and press <Enter>
to return to the Bag Setup Menu.
NOTE: After making adjustments, test the seal strength prior to beginning production. It is normal
for the indicator light to illuminate (pulse) during operation. As the actual temperature approaches
the set temperature, the pulses will get shorter and shorter. When the heater bar is up to temperature,
the Waiting LED indicator will change to Ready. From a "cold" start, it takes approximately four
minutes to reach the set temperature.
