The electrical cabinet does not contain any parts relevant for operation. It
contains only the electrical components needed to heat the melter and
measure temperature. In some cases there may be other components for
evaluating pressure sensor signals or for level monitoring. The melter is
controlled by the customer's parent machine.
Component designation: XS 2.
Transmits the digital input and output signals between the parent machine
and the Nordson melter.
The long level sensor (1) is connected to the analog level display and
3
transmits filling signals for a filling valve.
The short level sensor (2) serves as separate overflow protection. The
signal is made available to the customer for further evaluation at the
interface Level control. It is not evaluated by the control unit.
The filling valve (3) for automatic tank filling is located on the tank.
The filling valve control module opens when the solenoid valve is triggered.
The material is conveyed into the melter tank, e.g. by a bulk melter.
