TROUBLESHOOTING
NOTE: Before any assumptions are made regarding an apparent fault, first check the
input supply voltage. The voltage should be within ± 10% of the rated supply (i.e.
115VAC or 230VAC). Any variation from these parameters can result in controller
malfunction.

malfunction.
Controller Glues Every Other Sheet
Is the Trigger Device (photo eye) too far ahead of the Glue Applicator? The controller
could still be performing a gluing cycle on “Product #1” when “Product #2” is detected if
the physical distance between the Trigger Device and Glue Applicator is greater than the
gap between sheets. The TPC-2 Control Unit will not respond to a Trigger Signal until
the previous gluing cycle has been completed.

Glue Line Moves or Changes Length
The TPC-2 Control Unit has only the Trigger Device input that it can use to accurately
apply a glue pattern. Great care should be taken to ensure that the Trigger Device
sensitivity and vertical positioning are correctly adjusted as per the Trigger Device’s User
Manual. Things to check include:

sensitivity and vertical positioning are correctly adjusted as per the Trigger Device’s User
Manual. Things to check include:
1. Does the sheet change speed after it has been detected by the Trigger Device?
This could occur due to drive device slippage, detecting the product during the transition
from control by a “feeding device” to control by the “drive device” or there may be some
kind of obstruction in the feed path, such as dried glue. Tightening or replacement of
worn drive devices my resolve this problem. Moving the Glue Applicator and Trigger
Device to a different point on the machine may also be a solution.

2. Is the speed of the parent machine constant?
It is essential that once the TPC-2 Control Unit has been programmed that the speed of
the machine is not changed. Any machine speed change will require reprogramming the
TPC-2 to again achieve proper glue pattern positioning on the product.

Glue Applicators Will Not Activate
1. Is the Trigger Device activated for a shorter duration than the programmed DELAY for
EVENT1?
EVENT1?
The TPC-2 avoids “false triggers” by requiring that the Trigger Device be activated for at
least the duration of the DELAY programmed into EVENT1 of each CHANNEL.
least the duration of the DELAY programmed into EVENT1 of each CHANNEL.
2. Is the red LED above the RUN/STOP button illuminated?
