CURRENT TRANSFORMER INPUT FOR OUT FAILURE
DETECTION
The instruments equipped with this feature are capable, by
means of a CT, to detect and signal a possible failure of the line
driven by a control output programmed as a time proportioning
output (see "OUT failure detection").
Input range: 50 mA AC.
Scaling: programmable from 10 A to 100 A (with 1 A step).
Resolution:
- for full scale up to 25 A: 0.1 A.
- for full scale from 26 A to 100 A: 1 A
Minimum duration of the period (ON or OFF) to perform the
measurement: 120 ms.
