Section 10—Troubleshooting
Problem Possible Cause Possible Solution
Glue Pattern
1. At low speed, the
pattern length is too
short or too long. 1a. Either the “flap” or the “glue”
value is incorrect.
1b. Ratio compensation is incorrect.
1a. Ensure that the “flap” and “glue”
values have been correctly
entered.
1b. Ensure that ratio compensation
has been correctly entered.
2. At low speed, the delay
is too short or too long
before the pattern starts. 2a. “Flap” value is incorrect.
2b. Ratio compensation is incorrect.
2c. Cell-to-gun value is incorrect.
2a. Ensure that the “flap” value has
been correctly entered.
2b. Ensure that the ratio
compensation has been correctly
entered.
2c. Ensure that the cell-to-gun value
has been correctly entered.
3. At high speed, the
pattern length is too
short or too long. 3a. Either the “flap” or the “glue”
value is incorrect.
3b. Pattern length is incorrect at low
speed.
3c. Either the on or off compensation
is incorrect.
3a. Ensure that the “flap” and “glue”
values have been correctly
entered.
3b. Ensure that the pattern length is
correct at low speed.
3c. Ensure that the on and off
compensations have been adjusted
properly.
4. At high speed, the delay
is too short or too long
before the pattern
begins. 4a. “Flap” value is incorrect.
4b. “Flap” position is incorrect at low
speed.
4c. “On” compensation is incorrect.
4a. Ensure that the “flap” value has
been correctly entered.
4b. Ensure that the “flap” position is
correct at low speed.
4c. Ensure that the “on”
compensation has been correctly
entered.
5. There is a drop of glue
at the end of the product 5a. Air in glue line
5b. Glue viscosity too low
5c. Defective O-ring
5d. Too much guide-spring tension
(too much product movement at the
glue station)
5a. Purge air from glue line.
5b. Increase glue viscosity to 1500-
2000 cps.
5c. Replace O-ring.
5d. Decrease guide-spring tension.
