8.3.3 Optional: External blow-off connection (EB)
The ejector is also optionally available with an additional compressed air connector for the blow off func-
tion.
With the external blow off function (EB), the blow off pulse is controlled separately and independently of
the compressed air supply for vacuum generation, allowing you to use a different medium (e.g. nitrogen)
for the blow off function.
It also allows you to precisely set the blow off pressure using an external pressure regulator (between 2
and 6 bar).
The blow off flow rate can also be set between 0% and 100% directly on the ejector. This can be used, for
example, to set down small and lightweight workpieces with high positioning precision.
The hose size and the thread on the connector depend on the particular ejector and can have the follow-
ing dimensions:
•
Push-in: 4/2
•
M5 female thread

Connect the compressed air hose for external
blow off (connector marked with 1A) and ad-

screw (2).

Electrical connection may be performed only by a qualified specialist who can predict
the effects that signal changes will have on the entire system.
NOTE
Incorrect power supply
Destruction of the integrated electronics
4
Operate the product using a power supply unit with protected extra-low voltage
(PELV).
