Automatic reset (P3.10.1)
Activate the Automatic reset after fault with this parameter.
NOTE:
Automatic reset is allowed for certain faults only. By giving the parameters
Undervoltage flt (P3.10.6) to Wait Time (P3.10.13) the value 0 or 1 you can either
allow or deny the automatic reset after the respective faults.
Wait time (P3.10.3), Trial time (P3.10.4), and Number of trials (P3.10.5)
The Automatic reset function keeps resetting the faults appearing during the time set with this parameter. If the
number of faults during the trial time exceeds the value of Number of Trials (P3.10.5), a permanent fault is
generated. Otherwise, the fault is cleared after the trial time has elapsed and the next fault starts the trial time
count again.
Number of Trials (P3.10.5) determines the maximum number of automatic fault reset attempts during the trial time
set by this parameter. The time count starts from the first auto-reset. The maximum number is independent of the
fault type.
