 Self-diagnosis  Parameters
 Check of continuity of internal connections  Alarm due to disconnection: rating plug, sensors, trip coil      Note: Opening of circuit
 Failure of circuit breaker to open (ANSI 50BF)  Alarm following non-tripping of protection functions  breaker can be set in the
          event of alarm
 Temperature (OT)  Prealarm and alarm for abnormal temperature
 (1) with auxiliary supply present
 Note: In case of Black trip units, 0.4% In is the lowest current value detected by Emax 2
