6.6.1
Over Load error
Code, Type, Offending value:
Time stamp:
Event:
In OVERBOOST mode,
Iout > Iout_nom
for more then 5 seconds. The device enters a hiccup cycle.
6.6.2
Over Temperature error
Code, Type, Offending value:
Time stamp:
Event:
transformer temperature > 125°C (257°F).
The device trips to thermal shutdown.
6.6.3
Output Overvoltage error
Code, Type, Offending value:
Time stamp:
Event:
Unit internal error
. The output voltage can be no more regulated and it trips to its maximum value. When such error
occurs the device goes in a latched shutdown mode. A mains power cycle is needed to recover from such error.
6.6.4
Input Under Voltage error
Code, Type, Offending value:
Time stamp:
Event:
Vin < 330VAC
. The SMPS remains switched off until Vin > 340VAC
6.6.5
Input Over Voltage error
Code, Type, Offending value:
Time stamp:
Event:
Vin > 530VAC
. The SMPS remains switched off until Vin is decreased below 520VAC
6.6.6
PFC Under Voltage error
Code, Type, Offending value:
Time stamp:
Event:
VPFC < 300V
. The internal PFC bus voltage can be no more regulated. When such error occurs the device goes in a
latched shutdown mode. A mains power cycle is needed to attempt a recover from such error. Most of the cases this is an
unrecoverable error and the device needs to be serviced.
6.6.7
PFC Over Voltage error
Code, Type, Offending value:
Time stamp:
Event:
VPFC > 450V
. The internal PFC bus voltage can be no more regulated. When such error occurs the device goes in a
latched shutdown mode. A mains power cycle is needed to attempt a recover from such error. Most of the cases this is an
unrecoverable error and the device needs to be serviced.
