2. Start transmission of power.
Status bar for the overload capacity (user interface) Fig. 35
As soon as a higher phase current and AC power that is
higher than the nominal apparent power is called, the sys-
tem can supply this for a certain time span.
During overload operation, the overload capacity is reduced
continuously. The still remaining overload capacity is dis-
played on the user interface in percent in the form of a sta-
tus bar. As soon as the overload capacity has dropped to
"0%", only operation at nominal apparent power is possible.
To restore the overload capacity, the AC-DC module must
be operated for a period of time at less than 90% or less
than 80% of the nominal power.
Examples: Reduce and then again increase
overload capacity
The overload capacity drops from 100% to 0% if the system is
operated at overload with:
■ AC power set value between 100% and 125%.
For 10 minutes.
or
■ AC power set value between 125% and 150%.
For 1 minute.
The overload capacity increases again from 0% to 100% if the
system is operated under normal load with:
■
AC power set value of <90%.
For 20 minutes.
or
■ AC power set value of <80%.
For 10 minutes.
