Loss of the supply voltage
At a loss of supply voltage at U
L1
(phase 1), all measurements are interrupted.
After the supply voltage is restored, the AI Energy Meter 480VAC ST operates again with the
configuration / parameter assignment stored in the CPU. The retentively stored values are
used at the following counters and calculations:
● Energy and overflow counters
● Operating hours counters
● Counters for limit violation
● Minimum values
● Maximum values
Input data to "0"
Note
If the
AI Energy Meter 480VAC ST is no longer recognized by the interface module (for
example, because it is defective or not plugged in), all input data are set to "0".
