Options
Level Display, Level Control / Overflow Protection
With the option Level display (variable measuring points) an analog level
sensor is built in. A contact Fill tank is made available at the Standard I/O
(XS2) interface.
With the options Level control the analog level sensor (1) transmits filling
signals for a filling valve.
With the option Level control (fixed measuring points), a 5-point sensor is
built in. A contact Fill tank is made available at the Standard I/O (XS2)
interface.
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 industrial PC.
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.

Motor Circuit Switch
All motor controllers and motors are deenergized with the motor circuit
switch (motor maintenance or repair switch).
Position 0/OFF = Motor(s) switched off.
Position 1/ON = Motor(s) switched on.
This is important when, in the event of maintenance or repair, the melter
and heaters must remain switched on but the motors absolutely may not
turn.
Padlocks can be used to protect the motor circuit switch from being turned
on by unauthorized personnel.
