Rinsing unit
i
Connect the rinsing unit using a 2-core wire
with connector to the X3 connection of the
control�
At the connection for the rinsing unit, a
suction unit relay, for example, can be
connected if there is no isolation pres-
ent between the suction unit signal and
station selection valve in the treatment
unit� Note the power consumption of the
suction unit relay�
Display panel
The display panel is used to indicate
messages acoustically and visually (via
LEDs)�
A display panel is already integrated in the unit
and should be visible/audible at all times�
If the display panel is not visible/audible, fit an
additional display panel in an easily visible loca-
tion� The display panel is connected to the X6
socket (RJ-45 socket)� An existing Dürr Dental
display panel with a 6-pin connector can be
connected to the X6A connector when replacing
an older device�
If the installation of the amalgam separator in a
neighbouring room or in the basement results
in distances of more than 3 m, we recommend
installing a shielded network cable with RJ-45
sockets�
