Troubleshooting
This chapter lists possible problems of the DY2008 and how to solve them. If
malfunctions occur on the glue system and no obvious error indications are shown on
the controller, then you should also check that:
- The glue system is switched On
- The system has the proper AC input voltage
- The system has pressurized air
- All pneumatic and electric connections are correct
- There is enough adhesive in the tank
- All components are at operating temperature (hot melt only)
Error Messages of the DY2008 Controller
Communication Error
This is an internel error that can only be repaired by ITW
Dynatec personnel. In this case consult with the
Technical Service Department.
Over Current Failure
An output channel of the controller has registered
excessive overload. The display will show the
corresponding channel number.
Troubleshoot according to the table on the following
page.
Compensation Error
This message will be displayed when an attempt to
program an OFFSET or PATTERN value conflicts with
a previously programmed COMPENSATION value for
that channel. The 2008 controller will revert the
OFFSET or PATTERN value to the maximum
acceptable value. Further changes to these
parameters can only be accomplished by first adjusting
the corresponding COMPENSATION values.
