3. Functional description

The conveyor hopper is used for the automatic conveyance of freely flowing plas- tic granules. The hopper can only function in connection with a vacuum conveyor plant.

The hopper works without a filter. Depending on the type of valve, the shut-off valve of the vacuum line is operated with compressed air (compressed-air valve) or with the vacuum air (diaphragm valve).

On the hopper, there is a separate on/off switch (A) and a function controlling de- vice which indicates the following operational modes:

(B): lamp on - hopper switched on at the on/off switch (A); lamp flashes - the hop- per is conveying

(C): lamp flashes - error

(D): lamp is on - hopper signals lack of material
