Screen Message Explanation and Action
Communications Error This warning appears when there is an unspecified problem with the LA404.
If the problem persists, contact your Nordson representative for assistance.
Lost encoder signal
This warning appears when the encoder signal is not detected (encoder did
not move while the system was in the Run mode and at least 2 trigger signals
were received).
To correct this, confirm that the encoder is working correctly.
Encoder missing
This warning appears when RUN-mode is activated by pressing the STAND
BY-button but there is no encoder connected.
Max bead exceeded
This warning appears if the distance limit from one edge of the bead to the
other edge of the bead has been exceeded.
To correct this, make the beads smaller, make the gaps between each bead
smaller, change the encoder gearing, or decrease the GTO.
Ch1 short circuit
Gun Driver Overload. This fault appears when the loads on the gun driver is
drawing more than 100 Watts. This may be due to too many guns
connected, improper settings, or defective loads.
To correct this:
Check spike time and hold voltage settings for the type of gun used.
Check resistance of guns being driven.
Electric guns should be greater than 8 ohms and pneumatic valves
should be greater than 45 ohms.
Check the cable for a short.
The gun driver may be defective.
Ch2 short circuit
Ch3 short circuit
Ch4 short circuit
Engine Warning Codes
The warning codes appear as numeric codes on the menu screen. To
correct the condition, default the pattern controller to the factory settings. If
the problem persists, contact your Nordson representative for assistance.
