8. Optional features
8.1 AUX-connection (optional)
Safera PCU6.3 and PCU6.1 power control units
Ⓑ
(with software version 6.2.21 or
newer) are equipped with two auxiliary output signals AUX1 and AUX2 compatible
with most automation and security systems. They can be used to send real-time
status information of the stove guard.
8.1.1 Electrical specifications
• Optoisolated and potential-free AUX-
outputs: no galvanic connection
between the Airis system and the
automation system.
• When the AUX outputs are active
(ON), the optoisolator’s output
transistors will be held in conducting
mode, thus enabling current flow
from IN to OUT. This connection
can be used exactly as a relay’s
contact, however the direction and
amount of the current flow must
be controlled as specified below.
If necessary, the output states can
also be inversed.
• Maximum IN-OUT voltage is 24 VDC.
• Maximum IN-OUT current is 10 mA.
• Only DC voltage between IN-OUT,
no AC is permitted!
8.1.2 Coupling AUX-wire to the
power control units PCU6.X
Connect
AUX-wire to
the screw terminal.
Route the AUX-
wire through
the strain relief.
Mount the cover of the power
control unit
Ⓑ
with the screws
and ensure that the AUX-wire is
properly placed on the strain relief.
