Warnings
These are messages that are displayed on the menu screen to indicate a
warning condition.
Engine Warnings
The following engine warnings appear on the menu screen.
Screen Message Explanation and Action
Out1 queue overflow
This warning appears if there are more than 4 products between the gun and
its associated trigger. There should never be more than 4 products between
the trigger and the gun. If this occurs, the pattern controller will not generate
pattern on the additional products between the gun and trigger.
To correct this, increase the distance between products or decrease the
distance between the trigger and the gun.
Out2 queue overflow
Out3 queue overflow
Out4 queue overflow
Output 1 forced This is a pattern generation error that is caused by a gun not turning on or off
(or both) soon enough. The bead start point or end point has already passed
when the signal is sent to the gun actuator.
To correct this, decrease the line speed or add more space between the
trigger and the gun, or between the beads.
Output 2 forced
Output 3 forced
Output 4 forced
TRG1 too short This warning appears when the pattern for a channel exceeds the product
length as seen by the assigned trigger.
Verify proper product placement. This is an indication that the pattern would
not fit onto the product as measured by the trigger. It could indicate a jam or
skewed product.
TRG2 too short
TRG3 too short
TRG4 too short
T1 max dist exceeded
This warning indicates that the measured product length is longer than the
user entered maximum product length. Also refer to Jamming.
To correct this, check for a possible jam on the production line.
T2 max dist exceeded
T3 max dist exceeded
T4 max dist exceeded
Trigger queue full The warning indicates that more than 2 products are located between the
trigger and gun.

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.
