PISTON ADHESIVE MELTERMELTER OPERATION

Sensitivity adjustment
The adjustable sensitivity of the sensor
is factory pre-setted and therefore it is
NOT necessary to change. In most cases the factory setting is perfectly valid to
use the automatic feeder.
Positioning of the level sensor
The sensor is supplied factory set so that, when the pellet level is around 10
mm below the sensor, it detects a full tank (green LED).
Depending on the type of pellet used, it may be necessary to make a final
adjustment when starting up the system:
Important: Use the working adhesive at the operating temperature.
Warning: Hot zone with high temperatures. Risk of burns. Use thermal
protective equipment.
1. With the unit at the operating temperature and the sensor clean, fill
the tank with the pellets that you are going to work with, up to what is
considered the ‘tank full’ level.
2. Move the capacitive sensor up/down in relation to the tank lid, right until
the colour of the LED changes from green to red. The LED should remain
red.
3. We recommend checking that it is properly set by running a few automatic
reloading cycles.
Note: If the sensor sensitivity setting needs to be corrected, contact Meler’s
after sales service or the area representative.
