Function / Concepts
Raising and Lowering Platen
The pneumatic cylinders raise and lower the platen. When lowering the
platen, a two-hand control must be operated for safety reasons until the
platen is in the container. The selector Raise/lower platen then lights up
green.
Deaerating Container
The air relief valve must be opened manually to allow air to escape when the
platen is lowered into the container.
Aerating Container
To prevent a vacuum from forming when the platen is lifted out of the
container, the container must be aerated manually.
Platen Position
WARNING: Risk of squash! Make sure that switch 1 is not actuated until the
platen is inside the container.
A switch rod activates the switches (1 and 2) one after the other, triggering
the following switching functions:
