Status message
Description
0 = Off
Power supply system is shut down.
1 = ErrorOff The power supply system was automatically shut down as a result of
operation under inadmissible operating conditions.
2 = ReadyForRestart After an automatic shutdown due to fault, the power supply system can
be reactivated by switching off and switching on the supply voltage.
3 = Boot The power supply system is powering up, all of the outputs are still
switched off.
4 = Running
The power supply system is operating in the normal mode.
5 = Phasefail Phase failure of the supply voltage detected. The power supply system
can continue to operate in normal mode without any restrictions for a
limited period of time.
6 = SystemOverload (IP) System overload detected within the permissible overload profile. The
power supply system is still operating in the normal mode.
7 = SystemOverload (OP) System overload detected outside the permissible overload profile.
Power supply system only operating with some restrictions.
8 = SystemOverload (PL) Very high, brief load peak detected. Power supply system is operating in
the normal mode.
9 = Buffering Primary supply voltage has failed. Power supply system is operating in
the buffer mode.
10 = SystemOverload (IP)
during buffering
System overload outside the permissible overload profile detected. The
power supply system is still operating in the buffer mode.
11 = SystemOverload (OP)
during buffering
System overload outside the permissible overload profile detected. The
power supply system can only operate with restrictions.
12 = SystemOverload (PL)
during buffering
Very high, transient peak load detected. Power supply system is operat-
ing in the buffer mode.
