Version Changes
IEC
Bug fixing:
●
Correct command originators are now reported by
rcb upon change of control point.
SFMON
Bug fixing:
●
Self-monitoring of internal supply voltages (15V,
-15V, 24V) and output relay contacts has been
corrected to cope all kind of defects
MAIN New group signals have been implemented with fixed
meaning:
●
(019 201) MAIN Sat.discr. trigg
= saturation discriminator picked up in at least
one measuring system
●
(019 213) MAIN Inrush blk. trigg
= inrush blocking picked up in at least one
measuring system
●
(019 202) MAIN Overflux bl. trigg
= overflux blocking picked up in at least one
measuring system
●
(019 214) MAIN Harm.block. trigg
= inrush or overflux blocking triggered
●
(019 200) MAIN REFn trip signal
= any REF element tripped
Additionally 8 user configurable group signals have
been implemented:
●
(019 192) MAIN Group signal 01 to
(019 199) MAIN Group signal 08
For each of them up to 32 internal signals can be freely
combined using Boolean operators NOT, AND, OR.
These state signals are continuously updated, but with
no latching nor settable pick up/ release delay timers.
The configuration lists of general trip commands has
been updated to incorporate new group signals and
TRMON trip signals.
FT_RC Disturbance recording of neutral currents and voltage
has been made user settable (to avoid recording if no
CT/VT is connected).
The configuration lists for fault recording triggers has
been updated to incorporate new group signals and
TRMON signals.
Bug fixing:
Binary signals are now correctly recorded during the
whole post-fault period.
