• Check the cable connections to ensure they are firmly in place and making good contact.
The connection of AIRSKIN® to a controller is described in more detail in the installation instructions for the
specific type. In general, the connection is made as follows (see
AIRSKIN® CONNECTION BOX CONTROLLER
24 V DC
from controller or external power supply (PELV/SELV)
Ground/GND
If using an external power supply, ensure correct potential equalization
between the power supply and the controller!

shows the connection of the AIRSKIN® Connection Box to the controller and the connection to an
AIRSKIN® pad. By default, AIRSKIN® pads are connected to the AIRSKIN® Connection Box using a LEMO con-
nector cable. Another option is to connect the AIRSKIN® pads with a JST plug whose socket is behind a cover.
Parallel operation
The parallel connection of two AIRSKIN® systems via LEMO and JST connectors on the
same AIRSKIN® Connection Box can cause the safety cables to remain closed even though
one of the two AIRSKIN® systems claims an error. This operation is prohibited!
It is possible to supply the AIRSKIN® Connection Box via an external power supply, rather than through the con-
troller. This can be done via the clamp of the AIRSKIN® supply cable or via an integrated

DC socket on the
AIRSKIN® Connection Box. The latter is located behind a bolted cover as shown in
. Behind this cover is
a slide switch next to the DC jack, the so-called Energizer switch. In the normal state, the switch is in the position
shown in
By switching the Energizer switch, the two safety channels of the AIRSKIN® Connection Box are galvanically
isolated from the safety outputs of the controller (
and
) and connected directly to
+
24 V DC
. This so-
called Energizer mode only serves to test the AIRSKIN system without the safety outputs of the controller, and is
therefore not permitted for normal operation.
Energizer mode
In Energizer mode, the safety outputs of the controller are galvanically isolated from the
respective safety inputs. With activated safety pulses on the two safety channels, this
leads to a fault in the controller.
