Only on the 3UG4583-1CW30.
2)
Possible setting error: The threshold for shutdown is set to a higher value than the warning
threshold, and non-volatile (retentive) fault storage is set simultaneously with autoreset.
3)
The device has tripped following an insulation fault. The fault has been stored and the insulation
resistance has reverted to a value above the set threshold including hysteresis.
4)
Dependent on the fault.
The switching behavior of the output relay is shown in Chapter "Functions (Page 227)".
