7.5 Optional: External blow-off connection (EB)
The terminal is also available with an additional compressed air connector for the blow-off function.
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 respective ejector disc. 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 disc and can have the fol-
lowing dimensions:
• Push-in: 8/6
• Thread: 1/8" thread, female

Connect the compressed air hose for external
blow-off (connector marked with 1A) and ad-
just the blow-off flow rate using the adjusting
screw (2).

7.6 Electrical Connection
NOTE
Incorrect power supply
Destruction of the integrated electronics
4 Operate the product using a power supply unit with protected extra-low voltage
(PELV).
4
The system must incorporate safe electrical cut-off of the power supply in compliance
with EN60204.
4
Do not connect or disconnect the connector under tension and/or when voltage is ap-
plied.
The electrical connection is established directly via the connection plugs of the valves. The connection of
the valves is independent of the polarity.
