[Cause]
The limit time elapsed while the nozzle pressure was higher than the set value, or material leaked due to a rupture in the upstream hose.
[Countermeasure]
Use the dispensing equipment's diagnostic function to check that the nozzle pressure sensor operates correctly. Replace the sensor if necessary. Check whether the glue gun or nozzle contact tip is clogged. Replace the hose if it is ruptured.
