9.3.8 Secondary system supervision
9.3.8.1 Overview
Under Secondary circuit supervision there are settings for Current circuit
supervision and Fuse failure. There are five instances of Current circuit supervision
with parameters for minimum operation current, rated current and operation. There
are six instances of Fuse failure supervision parameters for setting rated current,
voltage, operation mode and several other parameters.
