Advanced Poly-Packaging T-1000 - Replace Thermocouple Wire; Preventative Maintenance and Scheduled Maintenance

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. Let machine cool for at least an hour.
Remove the Gripper Plate and Teflon assembly, take note as to which side of the Teflon Sheet Bracket is
up (the SHORT side of the groove on the bracket will be up for Drop Frame or the LONG side of the
groove will be up for Standard Frame). Unplug the Heater Cartridge and Thermocouple wires, then
remove the two shoulder bolts holding the Heater Bar in the yolks. Remove the Heater Bar. 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 and reattach Heater Bar.
Note: there is a top side and a bottom side to the thermocouple eye, the top side is flat and shiny, the
bottom side has a slight groove in it. Attach the thermocouple wire so the top side is facing out.
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 ensuring the correct side is up, then reattach Gripper Plate.
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.
