Data Description Data type
PowerInterrupt WaitTime [ms] Time that elapses from initiating the shutdown
sequence until output 1 is shut down.
Unsigned32
PowerInterrupt InterruptTime [ms] Time for which output 1 is shut down. Unsigned16

Data Description Data type
Priority buffered
Channel 1 (0/255)
Prioritized buffering of output 1 When the power fails, output 1 of the basic
device can be prioritized to increase the available buffer time. In order that the
remaining buffer energy is only used for output 1, in buffer operation, all of the
additional outputs of the power supply system are shut down after half of the
nominal buffer time that is available. When the line supply is available, the
outputs that have been shut down are automatically switched-on again.
Unsigned8
Startup mode System start characteris-
tics: Defines the time
delay when switching on
the outputs after the de-
vice has powered up. For
a defined switch-on delay
time, the outputs are
switched on in a fixed
sequence 1, 2,… n with
an identical delay time
between the outputs. For
a variable switch-on de-
lay, each output uses an
individually specified
delay time based on a
common starting point.
0 = StartupDelayOff No on delay Unsigned8
1 = StartupDelay25 ms 25 ms on delay Outputs
are switched on in an
ascending sequence
(starting with output 1 of
the basic device) in inter-
vals of 25 ms.
2 = StartupDelay
100ms
100 ms switch on delay
Outputs are switched on
in an ascending sequence
(starting with output 1 of
the basic device) in inter-
vals of 100 ms.
3 = StartupDelayLoad
Optimized
Load-optimized switch on
delay: Outputs are
switched on in an ascend-
ing sequence (starting
with output 1 of the basic
device) in a load-
optimized fashion.
4 = StartupDelay
Variable
Variable switch on delay:
Depending on the param-
eterized delay time, out-
puts are activated after
the supply voltage is
switched on.
Ithreshold (0-100 %) Prewarning threshold for the actual system power, referred to the rated power
of the power supply system.
