In relay patch software 2.1.2, the Start value setting range has been extended to start from 0.2
xIn. There is a limitation to the new extended setting range 0.2…1.0 xIn. Firstly, the extended
setting range is settable only from the LHMI. New range values cannot be set from the relay
tools. Secondly, when Start value is set below 1.0 xIn, the Operate delay time setting must be ≥40
ms to avoid degrading the relay surge immunity, and to avoid relay faulty operations due to high
surge spikes.
