Anti-Jam Adjustment - Advanced Poly-Packaging Advanced Poly-Bagger T-1000-S18H Operation Manual

4.11 Anti-Jam Adjustment

The anti-jam device is designed to protect the T-1000-S14 from damage when an obstruction is
encountered in the seal area, between the pressure bar and front gripper plate. If properly adjusted, the
pressure bar will retract if an obstruction is encountered in the seal area. The pressure bar houses springs
that cause the rubber and holder to compress. When the rubber holder compresses, a sensor is activated,
causing the pressure bar to retract. The sensor is defeated when the pressure bar is approximately 1/8"
from the gripper plate. See Figure 4-7. The anti-jam device can quickly be tested while the T-1000-S14 is
operating using care, but it should be thoroughly tested by disconnecting air and power and removing
covers.
To quickly test the anti-jam device, place a 3/8" diameter flexible poly tube against the front gripper plate
perpendicular to the seal bar opening. Press the foot switch allowing the pressure bar to compress the poly
tube against the front plate. If the pressure bar does not immediately retract and place the T-1000-S14 in
the STOP mode, the anti-jam device is not properly adjusted. Test the anti-jam device along the entire
length of the pressure bar using the 3/8" poly tubing as a test device.
CAUTION: To avoid personal injury, do not place fingers or hands into the seal area of the T-1000-
S14 while power is ON or air is attached. Do not test the anti-jam device with hands or fingers. Ensure
the poly tube that is used for testing is long enough to keep fingers or hands away from the seal area of
the T-1000-S14.
Part 1: Anti-Jam Test
To thoroughly test and adjust the anti-jam device, you must first turn the power to the OFF position and
disconnect the air line from the T-1000-S14. Remove Top Cover by unscrewing the two Button Head
Screws, one on each side of the top- rear of the machine. Keep these screws in a safe place. Remove the
top cover. With the covers removed and air disconnected, turn the power to the ON position.
With Power on, access the Main Menu on the Touch Screen, press Technical Assistance, and enter Level
1 Pass Code (1001). Press ENT.
On the Technical Assistance screen, press PLC Info to access the PLC I/O screen. You will be checking
to see if the X7 LED illuminates when the Anti-Jam is tested.
From the front of the machine, move Pressure Bar in until the rubber is approximately 1/8 inch from
touching the angle of the Gripper Plate.
Locate the Seal Rod and Magnetic Sensor Block on the left side of the T-1000.
With an Allen Wrench, loosen the Magnetic Sensor Block and slide Magnetic Sensor Block towards
Magnetic Switch until X7 just illuminates.
At this point, tighten the Magnetic Sensor Block at the place where X7 illuminated. Be sure it is straight
up and down and clears the Magnetic Switch.
CAUTION: To avoid damaging the plastic override sensor, position the sensor so that it does not
contact the magnetic block when the pressure bar is moving. To avoid "stripping" the threads of the
sensor, do not over tighten the securing nuts.
Re-Attach Air Supply by attaching the female quick-coupler to the male quick-coupler on the filter
regulator assembly.
Anti-Jam is working. Put the T-1000 in Auto Run and let it cycle. While it is running perform the Anti-
Jam test again by placing a piece of 3/8 tubing doubled over and place in between Pressure Bar and Heat
Bar. The Pressure bar should jump back and the Touch Screen should give an Anti-Jam error screen.
