Advanced Poly-Packaging T-1000 - 4.14 Heater Cartridge Replacement

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.
4.14 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
"Y0" LED (Heater Circuit) on the PLC Board (Fig. 4-8) or the Heater Status Light on the Touch
Screen Front Cabinet, beneath the Touch Screen (if installed on the T-1000). Press the
<START> key if the T-1000 is in the Stop mode. If "Y0" illuminates in long pulses without
increasing the Temperature on the Bag Setup Screen (page 32, Fig. 3-3) proceed to step two. 2)
Check the heater fuse (F5), on the Interface Board (Fig. 4-10). If the fuse is good, proceed to
step three. 3) Locate "N4" Neon Light (Heater Pulse AC) on the Interface Board (Fig. 4-9).
If the neon remains ON continuously, but at "half brightness", proceed to the final test. 4)
Disconnect the heater connector labeled "Heater" in the inner frame and check the resistance
with an Ohms meter. If the meter reads greater than 17-18 ohms, replace the newer style 800
watt cartridge. If the meter reads greater than 13 ohms, replace the older style 1200 watt
cartridge.
