Press the DOWN button to activate “blow off” on the ejector for as long as the button is pressed.
ð The H1 and H2 LEDs light up simultaneously.

By pressing the MENU button or through an external state change by signal inputs.
5.4 Viewing and Setting Parameters
The following parameters can be set for the ejector:
• Vacuum limit value H1 for the control
• Vacuum limit value H2 for the signal output
• Blow off duration for time-controlled blow off
The hystereses for the vacuum limit values are pre-defined. The hysteresis h2 is always 10 mbar.
The following tables show the various setting options with the corresponding parameter sets. A parame-
ter set is selected using the ejector buttons and is described in the next section.
Parameter sets
For H1, the hysteresis h1 is always 20% of the H1 value.

1)
If a value > (H1-h1) is selected for H2, the hysteresis h1 is dynamically adjusted so that (H1-h1) is 25 mbar
above H2.
With manual setting, the value set for H1 must always be greater than the value set for H2. Only settings
that meet this specification can be made.
Setting Parameters
The LEDs assigned to the parameters flash to indicate which value is currently being displayed or changed.
1. Press the MENU button to select the parameter to be changed:
Press once => first parameter “Vacuum limit value H1”
Press twice => second parameter “Vacuum limit value H2”
Press three times => third parameter “Blow off time”
ð The LED for the selected parameter flashes.
2. Change the selected parameter by pressing the DOWN or UP button.
ð The bar display LED increases or decreases.
