1.7 EVENTS
The events shown below can be flagged through communication with SCM-E-EIP.
Event Event Code Origin Meaning
Short Circuit
Protection SCP/OCP PSU Short circuit fault occurred at the output of the power supply.
This is triggered when the load current is greater than 150% of
the rated load.
Overvoltage
Protection OVP PSU The output voltage of the power supply is greater than 32V for
SDN10 and SDN20.
Power Boost
PB PSU Power supply loaded a reactive load which is less than 150% of
the rated load but greater than 125% of the rated load.
Overtemperature
Protection OTP PSU Internal temperature of the power supply exceeding safe
operating levels. This occurs when the main transformer
temperature exceeds 125°C.
