6.2
Signalisation at Master/Slave-operation:
The signal contacts for mains failure of the Master and the Slave must be connected in series to detect an
error signal from both units.
At the Slave the signal and the signal contact
Bat OK
are not active. (neither on the contact
Fault
, the master
takes over this function completly). If one unit switchs off because of overvoltage at the output, it is signalized
with the signal contact
Mains-OK
(at Master and Slave). Afterwards the mains voltage must be switched off
for a short time. (storing protection function).
6.3
Shutdown at Master/Slave-operation
The Shutdown is carried out at the Master as described in section 3.7, the mains voltage must be switched off
before.
6.4
Configuration Master/Slave
Configuration for Master-operation:
All power supplies also the replacement devices which are delivered from the factory are preset as
Master. Complete switch cabinets with Master/Slave configuration are adjusted correctly in the factory.
If a Slave must be replaced, the replacement unit must be adjusted as Slave.
Configuration for Slave-operation:
The unit must be completely switched off. On the upper side of the unit a double dip switch can be
seen through the grid. Press the dip with the indication
2
in the direction of the board. (ON). Verifica-
tion for example by the switch on of the unit outside the system. The output voltage amounts to ap-
proximately 22 V.
NOTE
During operation Master and Slave must be connected via ground at any time (Ua- or Bat-). A
separation of the wiring during operation is not allowed.
A lack of the signal
Sync
results in wrong measurement of the internal resistance of the accumu-
lator, the LED
Fault
illuminates herewith at the Slave.
A lack of the signal
CS
results in the overload of the Master, then the Slave only supplies ap-
proximately 22 V.
All load and all accumulator lines must be connected in parallel each with and connected with
separate lines at both
