256 13 N Different firmware version de-
tected
Different firmware version detected
256 14 N Different serial number detect-
ed
Different serial number detected
256 15 N Parameter out of permissible
value range.
A control command is attempting to set a value out-
side the value range that the hardware module can
implement. The value is automatically limited to the
minimum or maximum permitted value for the mod-
ule.

F
Critical error.
Critical error. Buffer component disabled.
256 17 F Shutdown due to overtempera-
ture.
Shutdown due to overtemperature. Buffer component
disabled.
256 18 F Invalid internal supply voltage. Invalid internal supply voltage. Buffer component
disabled.
256 19 MD Error while reading system
configuration from internal
memory
Error while reading system configuration from inter-
nal memory. The system is started with factory set-
tings.
257 0 N Parallel mode activated on
outputs 3 and 4.
Outputs 3 and 4 are working in parallel mode and
must therefore be connected externally.
257 1 F Shutdown due to phase failure
or unbalanced supply voltage.
Operation for phase failure or unbalanced supply
voltage for an impermissibly long duration. All out-
puts of the power supply system have been switched
off.
257 2 MD Phase failure or unbalanced
supply voltage.
Phase failure or unbalanced supply voltage detected.
Operation can continue for a limited time.
257 3 F Shutdown due to impermissible
supply voltage.
Supply voltage is outside the permissible limits. Out-
puts 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. Auto-
matic derating (limited performance) 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 over-
load.
System load current is outside the permissible over-
load 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 N Prewarning system overload. System load current is above the specified warning
threshold. Operation can continue without re-
strictions.
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 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.
