Heater Cartridge Replacement - Advanced Poly-Packaging T-1000-S14 Advanced Poly-Bagger Operation Manual

To test the antijam override sensor, locate the "X7" LED on the PLC board (Fig. 4-8) and ensure that the
light is OFF. Then, standing in front of the T-1000, push the pressure bar slowly towards the front plate,
keeping hands and fingers out of the seal area. While pushing the pressure bar towards the front plate do
not compress the rubber into the nylon holder or touch the round nuts on the pressure bar (Fig. 4-21).
When the pressure bar rubber is approximately 1/8" from the front plate, "X7" LED should illuminate
(ON).
If the LED illuminates prematurely (when the rubber is farther than 1/8" from the front plate), the antijam
override sensor must be adjusted. An aluminum block, located on the right guide rod in the inner frame,
houses a magnet (Fig. 4-22). The antijam override sensor detects the magnetic field sending the signal to
the PLC. If illuminated prematurely, the "magnetic block" should be moved toward the front of the T-1000
along the guide rod.
If the LED illuminates when the rubber is closer than 1/8" to the front plate or when the rubber is touching
the rubber plate (illuminates late), the magnetic block should be adjusted by moving the magnetic block
toward the rear of the T-1000 along the guide rod.
To move the magnetic block, loosen the screw on the block which secures it to the guide rod. Loosen the
screw just enough to allow the magnet block to slide along the guide rod without pivoting.
After moving the magnetic block, pull the pressure bar away from the front plate and check the
illumination of "X7" LED by pushing the pressure bar slowly toward the front plate. If out of alignment,
move the magnetic block in 1/8" increments until properly positioned. In its final position along the guide
rod, the magnetic block should be parallel to the side plate.
If the magnetic block, when parallel to the side plate and adjacent to the override sensor, does not cause the
LED to illuminate, adjust the override sensor so that the sensor is closer to the magnetic block.
The override sensor is secured to the side-plate with two plastic nuts, one on either side of the side-plate.
To bring the sensor closer to the magnetic block, loosen the nuts and turn the sensor counter clockwise,
from inside the frame. Turn the sensor 1/2 turn at a time or until the "X7" LED is illuminated. When
illuminated, turn 1/4 turn more.
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.
When properly positioned, secure the sensor by tightening the securing nuts. When properly adjusted and
thoroughly tested, tighten the screw on the magnetic block, replace covers and connect the air line to the
regulator.

4.13 Heater Cartridge Replacement

A cylinder-shaped cartridge (element), located inside the heater bar, heats the bronze bars which contain it.
This cartridge is considered a normal wear item and will infrequently fail, requiring replacement.
To determine if the heater cartridge is bad, follow the following troubleshooting steps: 1) Locate the "Y3"
indicator on the PLC info screen. See Fig. 3-26. Press the <START> key if the T-1000 is in the Stop
mode. If "Y3" illuminates in long pulses without increasing the Temperature on the Bag Setup screen
proceed to step two. 2) Check resistance value of heater cartridge, should read between 18-32 ohms.
