8.2 Description of parameters
Diagnostics overflow current
The measured current is monitored after expiry of the "Tolerance time" for "Overcurrent
[0.1 A] tolerance value". Exceeding this results in overflow current.

Diagnostics overflow voltage
Line voltage (measuring range) is monitored for tolerance. A violation of the overflow triggers
a diagnostic interrupt.
Diagnostics underflow voltage
Line voltage (measuring range) is monitored for tolerance. A violation of the underflow
triggers a diagnostic interrupt.
Diagnostics low limit voltage
Low limit for voltage is monitored. A violation of the low limit triggers a diagnostic interrupt.

The tolerance time starts as soon as the secondary current value (1 A, 5 A) is exceeded.
DIAG_UEBERLAST diagnoses the affected phase if the tolerance value of the secondary cur-
rent has been exceeded within the assigned tolerance time (or the maximum value of the se-
condary current (12 A) is exceeded).
After the set tolerance time has elapsed, the secondary current value (1 A, 5 A) is monitored. A
violation of the secondary current value also returns DIAG_UEBERLAST.
