The glue system will not operate if the TPC-2 Control Unit is in the STOP mode (red
LED above the RUN/STOP button is dim).
3. Is the Trigger Device operating properly?
The TRIGGER Status LED in the upper right corner of the TPC-2 Control Unit Display
Panel should illuminate for the duration of each TRIGGER input. Troubleshoot the
Trigger Device and connection cable if the Status LED is not illuminating.
4. Is the Glue Delivery System operating properly?
Adequate glue pressure must be supplied by the Glue Delivery System to assure proper
adhesive flow from the Applicator. Voltage measurements can be made from the Drive
Output of the TPC-2 Control Unit to determine whether it is functioning properly.
5. Is the Glue Applicator operating properly?
Troubleshoot the Glue Applicator and Drive Output Cable to assure they are functioning
properly.
6. Are the GAP, STITCH and SPIKE TIME settings inappropriate for the Glue
Applicator?
The response time of the Glue Applicator may be a limiting factor in applying a very
short gluing pattern. The TPC-2 Control Unit may be attempting to turn the Glue
Applicator ON and OFF so quickly that the Applicator is unable to respond and as a
result it is unable to apply glue.
7. Is the drive output of the TPC-2 appropriate for the Glue Applicator?
The TPC-2 Control Unit is capable of a “Spike Voltage” output of 48VDC with a
“Holding Voltage” of 16VDC at up to 26 Watts per CHANNEL. This may be insufficient
for some Glue Applicators that, by design, require either higher voltage, power, or both.
DRIVE or A.T.S. Status LED is Illuminated Red
There is a short circuit somewhere in the Drive Output circuitry.
1. Disconnect the Drive Output Cable.
2. Turn OFF the TPC-2 Control Unit, wait a few moments, then turn ON the TPC-2
Control Unit. The fault status should now be cleared.
3. Activate the Trigger Device, leaving the Drive Output Cable disconnected. The TPC-2
Control Unit is defective if the DRIVE fault is again indicated by the red Status LED. It
should be sent to ITW Dynatec for repairs.
