Data
Description
Data type
1 = ErrorOff The power supply system
was automatically
switched off due to opera-
tion under impermissible
operating conditions.
2 = ReadyForRestart After an automatic shut-
down due to a fault, the
power supply system can
be reactivated by switch-
ing off and switching on
the supply voltage.
3 = Boot The power supply system
is starting up, all outputs
are still switched off.
4 = Running The power supply system
is in normal operation.
5 = Phasefail Phase failure of the sup-
ply voltage detected. The
power supply system can
continue to operate in the
normal mode without any
restrictions for a limited
period of time.
6 = SystemOverload
(IP)
System overload within
the permissible overload
profile detected. The
power supply system
continues to operate in
normal mode.
7 = SystemOverload
(OP)
System overload outside
the permissible overload
profile detected. The power
supply system can only
operate with restrictions.
8 = SystemOverload
(PL)
Very high, transient peak
load detected. The power
supply system is in nor-
mal operation.
9 = Buffering Primary supply voltage has
failed. The power supply
system is in buffer mode.
10 = SystemOverload
(IP) during buffering
System overload within
the permissible overload
profile detected. The
power supply system
continues to operate in
buffer mode.
11 = SystemOverload
(OP) during buffering
System overload outside
the permissible overload
profile detected. The power
supply system can only
operate with restrictions.
