203 CVT Alarm
Alarm for capacitive voltage Transformer: Indicates the
residual voltage is greater than the threshold adjusted
in the settings, during a time-delay greater than the
adjustment. That alarm is also included in the general
alarm.

Block aided DEF time delay
The DEF time-delay will be blocked & DEF will start but
will not issue any trip command.
