Configuring the conference system via the central unit
108 | ADN Digital Conference System
If an error icon appears (see page 102), check your conference system for the errors
mentioned above.
Possible steps for error elimination:
Eliminate the errors separately for the ADN CU1 central unit, the ADN PS power
supplies and the respective affected PORT sockets.
Calculate the maximum length of the cable string or cable ring (see page 29)
and, if necessary, reduce the cable length.
Reduce the number of conference units to 15-20 max. per cable string or ring.
If necessary, further reduce the number of conference units until there are no
errors reported.
Then add conference units one after the other and observe the central unit’s
display panel. If an error is reported, the cause of the error might be the last
added conference unit, the cable used or metal parts that bridge the contacts
of the plug connection.
Displaying the temperature status –
“Temperature”
If the temperature of the ADN CU1 central unit and of
the ADN PS power supplies
is within the normal range, the icon appears behind “System”.
If the temp
erature of the ADN CU1 central unit and the ADN PS power supplies
exceeds the limit values, the icon appears behind “System” and the affected
compo
nents are listed together with the icon below “System”.
Examples for the
listing of affected components:
V
--
The PORT socket is deactivated due to e.g.
no conference units connected/faulty antenna module
a short-circuit
P The power of the ADN CU1 central unit or ADN PS power supply is
not sufficient because too many conference units are connected.
P
--
Information on the power output of the ADN CU1 central unit or
ADN PS power supply is not yet available.
If an error is detected at startup of the central unit, first eliminate the error
and
t
hen perform a manual self-test (see page 110) to check if the error still
persists.
If an error has only occurred during operation and has already been elimi-
nat
ed, this
is automatically detected by the central unit.
