Preventative Maintenance - Advanced Poly-Packaging T-200 Operation Manual

3. Using a Multimeter set to "OHMS" Scale, place meter on Pins 3 and 5, Connector J3, Logic Control
Printed Circuit Board. Note: Pin 1 is the leftmost pin on Connector J3.
4. Manually push pressure bar inward until rubber strip slightly touches the Anti-Stick Shield evenly
across the pressure bar.
5. Loosen magnetic sensor collar located on the right seal cylinder. Adjust the magnetic sensor by sliding
it along the cylinder until the meter LED is illuminated.
6. Tighten magnetic sensor collar ensuring that LED is continually illuminated.
7. Then place meter on Pins 4 and 5, Connector J3, Logic Control Printed Circuit Board.
8. Complete steps 4 through 6 for the left seal cylinder.
9. Manually pull pressure bar out and then push inward alternating meter from pins 3 and 5 to pints 4 and
5 testing to see if the meter LED is illuminated when the pressure bar contacts the Anti-Stick Shield.
10. Replace all covers, apply air and power and test cycle as described in Chapter 2, Section 2.4, Test 1
to ensure proper operation.
Test 2 Failed: Pressure bar begins to move inward when an obstruction is present or when an object is
pressing inward on the Anti-Stick Shield.
1. Remove air from the unit, turn the T-200 power "OFF" and unplug the power cord.
2. Remove the back (stainless) cover and side (painted) cover.
3. Using a Multimeter set to "OHMS" Scale, place meter on Pins 1 and 2, Connector J3, Logic Control
Printed Circuit Board. Note: Pin 1 is the leftmost pin on Connector J3.
4. Manually push pressure bar inward until rubber strip slightly touches the Anti-Stick Shield evenly
across the pressure bar.
5. Then continue pressing inward on the right side of the pressure bar which will press the spring-loaded
Anti-Stick Shield inward.
6. Continuity should be present when the right side of the pressure bar is pushed inward, pressing the
Anti-Stick Shield inward. If no continuity is read, adjust the magnetic switch located on the rear
mounting bar on the heater bar assembly (See Dwg No T3-00161, Items 1-Rear Mounting Bar and 19-
Magnetic Switches). Secure locking nuts on magnetic switch when properly adjusted.
7. Repeat steps 3 through 6 for the left side of the pressure bar.
8. Manually pull pressure bar out and then push inward alternating between pushing in the right and left
sides of the Anti-Stick Shield ensuring there is continuity when the Anti-Stick Shield is pushed inward.
9. Replace all covers, apply air and power and test cycle as described in Chapter 2, Section 2.4, Test 2 to
ensure proper operation.

3.8 Preventative Maintenance

The following maintenance items should be performed by the operator or maintenance personnel to
prolong the life of the equipment. Failure to perform these tasks may result in premature wear, personal
injury, or equipment damage.
Item: Description:
Anti-jam Test anti-jam prior to production
Pressure Check air pressure to ensure 40-50psi
PTFE Inspect for wear / holes / exposed nichrome
Rubber Strip Clean rubber strip with alcohol
Nichrome Wire Inspect for wear / damage. Tighten when
loose.
Cylinders Remove air and push in manually to ensure
free movement with no binding
Springs Inspect for cracks in springs, ensure free
movement
Wiring Ensure no loose contacts or worn shielding
Fasteners Tighten mounting bolts and fasteners
