Line Voltage
WARNING: The pressure controller LA 302 is designed to accommodate
the voltage stated on the unit port (1). It adapts to any voltage within the
given range.
1. Plug the power cable into the unit port (1) on the back of the pressure
controller.
2. Connect the power cable to the shockproof socket.

Encoder
The adhesive pressure is controlled as a factor of the production machine
speed. Thus an encoder (1) must be connected. A gear box connects it to
the production machine, and it delivers a pulse per mm.

Liquid Adhesive Gun
A solenoid valve triggered by the LA 302 opens and closes the adhesive
guns. The solenoid valve is located on the adhesive gun and is electrically
connected to the pressure controller.

Proportional Pressure Control Valve
The glue for the adhesive guns can be fed e.g. by a connected container
pump via a pressure regulator. The pressure regulator is controlled
(pressure rises as production speed increases) via a proportional pressure
control valve supplied by one of the pressure controller outputs. Two
proportional pressure control valves can be connected to these outputs.
