Description
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. 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.
Pressure build‐up feature 14 - E : One pressure sensor per pump. There is no
pressure control valve.
This feature allows the material pressure to be
regulated to an adjustable value as soon as the line
speed signal falls below an adjustable value.
Pressure display 15 - A : One pressure sensor per pump
The melter outlet pressure is displayed and
monitored. Alarms for underpressure and
overpressure are displayed.
Level display (fixed
measuring points) 16 - F : The level sensor measures the presence of
material at five different points.
Level Display and Control
(Variable Measuring Points) 16 - L : Level display
Level sensor in tank for analog level display
B : Level control (Ni120)
C : Level control (Pt100)
Level sensor in tank for the analog level display and
the filling signals for a filling valve.
Automatic tank filling is performed e.g. by a bulk
melter connected to the filling valve with a hose.
