Data
Description
Data type
12 = SystemOverload
(PL) during buffering
Very high, transient peak
load detected. The power
supply system is in buffer
mode.
Uout_OK (0/255) Status of output "UA-OK relay": Indicates whether all of the power supply sys-
tem output voltages are correct.
Unsigned8
Max device output
current [10mA]
Maximum output current of the power supply system. Unsigned16
Output Utarget [10mV]
Currently set setpoint of the output voltage.
Unsigned16
Output Ilimit [mA] Response threshold value of the output current for the particular output. When
this is exceeded, the output current is interpreted as having an overload condi-
tion and is shut down with a time delay - or limited.
The response threshold is set in the following steps depending on the maxi-
mum output current:
• Output current 20 A: 20 mA (0.02 A)
• Output current 40 A: 40 mA (0.04 A)
Values that deviate from this grid are rounded off to the next permissible value
in the device.
Unsigned16
Output Ithreshold
(0-100%)
Prewarning threshold of the configured response threshold for the output cur-
rent in %. An alarm is initiated when the actual output current exceeds this
value. Operation is continued without any restrictions. Prewarning is deactivat-
ed by entering "0 %".

Output voltage [10mV]
Voltage at the output.
Unsigned16
Output current [10mA] Output current at the output. Unsigned16
Max output current
[10mA]
Maximum output current at the output. Unsigned16
Output operation mode Output operating mode: If
the actual load current of
an output exceeds the
specified response
threshold value of the
output current, then the
output can be switched off
according to a current-
time characteristic
(ELECTRONIC
SHUTDOWN), or the load
current can be limited to
the response threshold
(CONSTANT CURRENT).
0 = ModeSelect Electronic shutdown: The
output is switched off
when the response
threshold value is ex-
ceeded.
Unsigned8
1 = ModeModular Constant current: When
the response threshold
value is exceeded, the
load current is limited to
the response threshold
until this is fallen below
again.
