Thermoplastic Hot Melt Material
NOTE: Always refer to the material manufacturer’s Material Safety Data
Sheet (MSDS) or material information sheet before working with any hot
melt material.
Ensure the work area is adequately ventilated.
Do not exceed recommended processing temperatures. Doing so
creates a danger to personnel due to decomposition of the material.
Action in the Event of a Malfunction
If a system or any equipment in a system malfunctions, shut off the system
immediately and perform the following steps:
Disconnect and lock out system electrical power. Close hydraulic and
pneumatic shutoff valves and relieve pressures.
Identify the reason for the malfunction and correct it before restarting the
system.

Description
Intended Use
Pressure controllers in the series LA 302 can be used to control proportional
pressure control valves and/or glue application pumps for Nordson liquid
adhesive guns. They are designed to process cold glue and hot melt
adhesive. The two integrated outlets for electropneumatic adhesive guns
allow continuous gluing. LA 302 units can be combined with Nordson
pattern controllers for intermittent gluing.
NOTE: Cold glue and other adhesives are referred to as glue in this
manual. The pressure controller is referred to as controller.
Unintended Use - Example -
The unit may not be operated in a potentially explosive atmosphere.
Residual Risks
WARNING: Do not touch the contacts after disconnecting the mains plug.
Capacitive charge from the electronic components causes the controller to
retain residual voltage, which could result in a slight electrical shock upon
contact. The capacitive charge is discharged after approx. 60 seconds.
WARNING: Glue escapes from the adhesive gun when the solenoid valves
are triggered. Risk of splashing. Wear safety goggles. Do not program
during adhesive gun assembly.
The risk is particularly high during:
Production machine startup
Reverse mode
Manual mode
