5.7
Shut-Down
Buffer operation can be interrupted early in order to avoid a discharge of the lead accumulator up to the deep
discharge limit. This can be done by connecting a +24 V DC control voltage to the terminal
3
(+Shut) and
4
(-
Shut) of the terminal strip
IO-2
.
5.8
Acoustic alarm transmitter (optional)
An alarm transmitter with VdS approval is available for emitting an acoustic warning signal if a general error
occurs.
6
Master/Slave-operation at parallel connection
This operational mode is only valid in case of parallel connection of two power supplies to double the total
power rating.
6.1
Connection at Master/ Slave-operation
To increase the power rating respectively for redundant operation it is possible to connect two power supplies
in parallel.
The temperature tracking is only carried out by the Master.
Master: IO-2:1,2
The fuse monitoring is also only carried out by the Master.
Master IO-2:7 to fuse board
The Sync-connection is necessary for the functions of the accumulator test. A lack of the signal results
in a wrong measurement of the internal resistance of the accumulator.
Master IO-2:6 to Slave: IO-2:6
The CS (Current-Share-Bus) is used to share the load between both power supplies. A lack of this
signal results in the overload of the Master unit.
Master IO-2:5 to Slave IO-2:5
The signal contact mains operation is at both power supplies active. They must be connected in se-
ries, to detect a mains failure of both units.
Master IO-1:4,5,6 and Slave IO-1:4,5,6
The signal contact
Bat-OK
is only active at the Master
Only Master IO-1:1,2,3
The signal contact General Fault is active at both power supplies. They must be connected in series.
Master IO-1:7,8,9 and Slave IO-1:7,8,9
