Minimum and maximum value calculation
Enable calculation of the minimum and maximum values here. The minimum and maximum
value are calculated from the start of the measurement. The calculated values are stored
retentively in the Energy Meter.
Diagnostics overflow current
The measured current is monitored after expiration of the "Tolerance time" for "Measured
current x 0.1 x Tolerance factor". A violation results in a current overflow.
①
The tolerance time starts as soon as the secondary current value (1 A, 5 A) is exceeded.
②
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 sec-
ondary current (10 A) is exceeded).
③
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.

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