VCHK setting
2.25.3
When the VCHK is applied to 1CB system, OVB and UVB check the voltage of a Busbar,
whereas OVL and UVL checks the voltage of Line, as described earlier. The Busbar and Line
voltages are obtained in the VCT
[SYN-VLine] in accordance with the phase(s) of input-voltage(s). The following are the setting
examples when VCHK is used in 1CB system.
Note: For more information on VCT, see
