Category: Issue for edition 2 of this part
Vendors should be able to allow open command of the breaker, even if the position indicates open position. Motivation: Personal safety: e.g. in some cases the position indication sensor could be jammed and opening is needed. Technically XCBR.BlkOpn/BlkCls (or CILO.EnaOpn/EnaCls) should be used if the opening is not possible due to internal condition of the breaker (spring charging, disconnector state). Closing breaker could still be inhibited if the position indication indicates close.
Allow the functionality descibed in issue in some cases or remove CtlN3.
