End of maximum set short-circuit disconnec-
tions
End of maximum set tripping operations
Reaching set temperature
Overcurrent alarm 1 in % of rated current

Undercurrent alarm 1 in % of rated current
Undercurrent alarm 2 in % of rated current
Overvoltage alarm 1 in volts
Overvoltage alarm 2 in volts

Base line is an average temperature that is determined over an adjustable time.
1)
Base line is an average current that is determined over an adjustable time.
2)
Base line is the average voltage which is fixed according to the standard, constant at 195 V and a hysteresis of 10%.

Note
Not all alarms are activated by default. All alarms can each be switched on or off.
The respective alarms can be activated or even deactivated. A message is not displayed if they
are deactivated and the device LEDs do not flash according to the pattern described above
(see Chapter LED signaling (Page 37)). Furthermore, there are adjustable setpoint values that
generate messages when they are exceeded. In addition, a hysteresis value can be set for the
alarms for current, voltage and temperature. An alarm is activated if a threshold value is
exceeded. If the measured value falls short of the setpoint value including the set hysteresis,
the alarm status is left again.
Chapter Measurement settings (Page 71) described which parameters are available with the
respective units, value ranges and default settings.
The aforementioned warnings are displayed in the device overviews for the respective
measured values. Furthermore, these are displayed in the Messages view with a time stamp.
