1)
To enhance user convenience, time settings for certain features will not be displayed when certain protection features are deactivated.
2)
CT ratio setting (ctr) can be set to less than 2,000 A in conjunction with the rc setting.
3)
The menu indicates oc-t when overcurrent settings are set at definite time (dEF), and cLS when set to inverse time (thr, nthr)
Code
