Description Explanation
The blow off signal overrides the suction signal, even if the specified
blow off time is very long.
The length of the blow off time [
tbL
] is set in the main menu. This menu item is suppressed in operating
mode [
-E-
].
The number displayed indicates the blow off time in seconds. Blow off times from 0.10 seconds to
9.99 seconds can be set.
7.7 Changing the Blow-Off Flow Rate on the Ejector
Do not overwind the stop on the valve screw. A minimum flow rate of approx. 15 % is always
necessary for technical reasons. The blow-off volume flow can be set between 15 % and
100 %.
There is a valve screw below the vacuum connection that can be used to adjust the blow-off flow rate.
The valve screw is equipped with a stop on both sides.

1. Turn the valve screw clockwise to reduce the flow rate.
2. Turn the valve screw counterclockwise to increase the flow rate.
7.8 Monitoring the Supply Voltages
The ejector is not a voltage meter! However, the measured values and the system responses
derived from them provide a helpful diagnostics tool for condition monitoring.
The ejector measures the supply voltages U
S
. The measured value can be read from the parameter data.
If the voltages are outside the valid range (min. 19.2 V and max. 26.4 V), the following status messages
change:
• Device status
• Condition monitoring parameter
• An IO-Link event is generated
There is no guarantee that the ejector will operate as intended below a supply voltage of 19.2 V:
• The reaction to signal inputs is disabled.
• The “Part Present” check output retains its normal functionality.
• The current supply voltage can still be viewed using the button.
