Voltage check mode:
The first letter refers to
the reference voltage and
the second letter refers to
the comparison voltage.
D means that the side
must be ―dead‖ when
closing (dead = The
voltage below the dead
voltage limit setting)
L means that the side
must be ―live‖ when
closing (live = The voltage
higher than the live
voltage limit setting)
Example: DL mode for
stage 1:
The U12 side must be
―dead‖ and the U12y side
must be ―live‖.
