Replace Thermocouple Wire; Preventative Maintenance And Scheduled Maintenance - Advanced Poly-Packaging Advanced Poly-Bagger T-1000-S14 Operation Manuals

Disconnect the heater cartridge wire at the connector. From underneath the inner frame, loosen and
remove the screws that hold the wire clamp and lower heater bar plate to the upper heater bar plate. See
Figure 4-8. Then remove the two remaining screws that hold the lower heater bar plate to the upper heater
bar plate. Remove the heater cartridge wires from the wire clamp. Place a new cartridge into the heater
bar slot and replace the lower heater bar plate. Place the wires into the wire clamp and secure to the lower
heater bar plate. Reconnect the heater cartridge wires, ensuring that the heater bar can extend fully
without stretching the heater cartridge wires. Plug the cord into the outlet, turn the power to the ON
position and connect the air line to the regulator. Press START on the touch screen and verify that the
temperature increases.
NOTE: Heater cartridge wires must make a sharp 90° bend at the end of heater bar. Wires should not
extend past the end of the heater bar.
NOTE: If the wires rub on the bagger when the heater bar is in or out, the heater cartridge will fall
prematurely.

4.14 Replace Thermocouple Wire

A thermocouple wire, brazed to a ring terminal and secured to the bottom of the heater bar, detects the
amount of heat the heater bar is emitting. The thermocouple wire is considered a normal wear item and
will infrequently fail, requiring replacement.
The thermocouple should be replaced when excessive fluctuations occur or incorrect temperature is
displayed in the Bagger Settings menu. The thermocouple should also be replaced when a visual
inspection reveals frayed insulation or broken wire. If the above conditions are met, the thermocouple is
bad and the current to the heater bar has been turned OFF.
To replace the thermocouple wire, turn the main power to the OFF position, unplug the power cord and
disconnect the air line.
Remove the front plate and Teflon assembly. Remove the screws that hold the ring terminal and the
jacketed wire clamp. Disconnect the connector and remove the wire. Reverse these steps to replace the
wire.
CAUTION: To avoid stretching or breaking the wire during heater cylinder extension, ensure that
the wire is looped and free to bend during heater bar movement.
Replace the Teflon assembly and front plate.

4.15 Preventative Maintenance and Scheduled Maintenance

To extend the life of the T-1000-S14, qualified maintenance personnel must perform all required
maintenance tasks. Failure to perform scheduled and preventative maintenance may cause excessive wear
to components and will void the warranty. For the purpose of this manual, preventative maintenance (PM)
tasks are considered periodic tasks that should be performed on a daily, weekly or monthly basis.
Scheduled maintenance tasks are performed when the T-1000-S14 Maintenance Chart Number changes to
a higher number. Scheduled maintenance tasks (CHART items) are performed depending on the number
of machine cycles and therefore are not considered "periodic" tasks.
