Description
Pneumatic pressure control 14 − The pneumatic pressure control valve replaces the
installed mechanical pressure control valve.
P : Automatic
A proportional valve supplies regulated
compressed air to the pneumatic pressure control
valve. It receives the line speed signal from the
parent machine needed for regulation.
M : Manual
The operator sets the required compressed air with
the pressure controller handwheel.
Bypass control 14 − F : The pneumatic pressure control valve replaces
the installed mechanical pressure control valve.
In normal production mode, the pressure control
valve is supplied with maximum air pressure
(approx. 6 bar) and is closed. The material is
conveyed to the melter outlet.
When the gun closes, the solenoid valve receives
an electrical signal. The pressure control valve is
supplied with regulated compressed air and begins
to open. The material is returned to the tank
(bypass).
Pressure display and
pressure control
14 − C : One pressure sensor per pump stream.
Double-stream pumps are equipped with two
pressure sensors: one for display and one for
control. There is no pressure control valve.
The desired pressure is set on the control panel.
The pressure sensor converts the pressure to an
electrical signal, which is used for control via the
CAN bus.
Flow control 14 − T : This function allows the speed to be regulated to
an adjustable value as soon as the parent machine
stops.
B : This function allows the material pressure to be
reduced through the pneumatic pressure control
valve when the motor stops.
Pressure build-up 14 − N : The mechanical safety valve with Reed switch
replaces the installed mechanical safety valve. One
pressure sensor per pump stream. Double-stream
pumps are equipped with two pressure sensors:
one for display and one for control. There is no
pressure control valve.
This feature allows the material pressure to be
regulated to an adjustable value as soon as the
parent machine stops or when the line speed signal
falls below an adjustable value.
