16. Run the system at maximum production speed and set the maximum
pressure for proportional pressure control valve 1 with potentiometer (D)
or the maximum pressure for proportional pressure control valve 2 with
potentiometer (G) such that the glue bead is even and cohesive
(production machine speed may need to be throttled). Lock the setting.
NOTE: If the quality of the glue bead is not satisfactory, continue to adjust
the minimum speed setting on the production machine and on the LA 302
and adjust the respective minimum pressure until the glue bead is correct. If
the production machine is run at a speed below the minimum speed set on
the LA 302, pressure control does not occur.

the solenoid valves are triggered. Wear safety goggles. Do not program
during adhesive gun assembly.
The risk is particularly high during:
Production machine startup
Reverse mode
Manual mode
NOTE: Mode switches and potentiometers on the front of the pressure
controller will be designated alphabetically as mode switch / potentiometer
(A), (B), (C), ... beginning at the top left and moving to the right. The LEDs
are designated LED (1), LED (2), ... beginning at the top left and moving to
