10
MD
Prewarning overtemperature
Danger of overtemperature detected in a
system component. Immediate load re-
duction is recommended.
256
11
F
Invalid internal supply voltage
Voltage of the internal supply is too high.
All outputs of the power supply system
have been switched off.
256
12
F
Performing firmware update

access is currently not possible.
257
-
F
Device failure
Device failure.
257
1
F
Shutdown due to phase failure or unbal-
anced supply voltage.
Operation for phase failure or unbalanced
supply voltage for an impermissibly long
duration. All outputs of the power supply
system have been switched off.
257
2
MD
Phase failure or unbalanced supply volt-
age
Phase failure or unbalanced supply volt-
age detected. Operation can continue for
a limited time.
257
3
F
Shutdown due to impermissible supply
voltage.
Supply voltage is outside the permissible
limits. All outputs of the power supply
system have been switched off.
257
4
MD
Supply voltage outside the nominal limits Supply voltage is outside the nominal
limits. Automatic derating (limited perfor-
mance) can occur when the voltage is
low.
257
5
MD
High-resistance internal supply.
High-resistance internal supply detected.
Check connections!
257
6
F
Shutdown due to system overload
System load current is outside the per-
missible overload profile. Outputs of all
expansion modules have been switched
off.
257
7
MD
System overload
System load current detected within the
permissible overload profile. Operation
can continue for a brief period.
257
8
MR
Prewarning system overload
System load current is above the speci-
fied warning threshold. Operation can
continue without restrictions.
257
9
MR
System is ready to switch on again.
System can be switched on again after
automatic shutdown due to impermissible
operating condition. Reset by switching
the supply voltage off and on.
257
10
MR
Outputs of the expansion modules can be
switched on again.
System can be switched on again after
automatic shutdown due to impermissible
operating condition. All outputs of the
expansion modules can be manually
switched on again.
257
11
MR
Buffer mode
The power supply system is supplied via
buffer expansion module(s).
257
12
MR
Device failure during startup
Device failure during startup.
257
14
F
Expansion module is not available
Expansion module was not found. Power
supply system response deviates from
the configuration.
