Check the value of the actual temperature of the laminating roll on the operator's panel. If it
exceeds the set acceptable limit 300 °F (150 °C), the most probable cause of the error is broken
solid state relay A2. See DA-41-100n, sheet 5. Replace it.
•
The error will reset as soon as the temperature of the laminating roll in its middle drops below
the set maximum acceptable limit 300 °F (150 °C).
