7.5 Process Data
During operation of the ejector, all input and output signals are connected to a controller, either directly
or using intelligent terminal boxes.
For this purpose, not only the supply voltage but also two input signals and one output signal should be
connected to allow the ejector to communicate with the controller.
The basic ejector functions such as suction, blow off and feedback are used with these signals.
In detail, they are:

7.6 Start of Operations
A typical handling cycle is divided into the following three phases: pickup, blowoff and idle.
To check whether sufficient vacuum has built up, the limit value H2 is monitored by an integrated vacuum
sensor during suction and output to the higher-level controller via OUT.
