Version Changes
SFMON Addendum:
As of version –605 the “memory function” for the
warning signal memory may be set. After the
associated timer stage has elapsed, a renewed
occurrence of a warning is processed the same way as
if it where a first occurrence.
The configuration table of the user defined alarm
condition has been accomplished by the instantaneous
and timed outputs 30…32(t) of the programmable
LOGIC:
●
(098 053) SFMON: Output 30 ~ (042 090)
LOGIC: Output 30
●
(098 054) SFMON: Output 30 (t) ~ (042 091)
LOGIC: Output 30 (t)
●
(098 055) SFMON: Output 31 ~ (042 092)
LOGIC: Output 31
●
(098 056) SFMON: Output 31 (t) ~ (042 093)
LOGIC: Output 31 (t)
●
(098 057) SFMON: Output 32 ~ (042 094)
LOGIC: Output 32
●
(098 058) SFMON: Output 32 (t) ~ (042 095)
LOGIC: Output 32 (t)
These logic outputs are included in the warning signals
by setting SFMON: Fct. assign. warning and they
are also recorded in the monitoring signal memory.
These signals can be used to create an alarm signal
under complex application conditions. This signaling
has no influence on the device's operation (i.e. no
warm restart or blocking).
FT_RC The recording duration for binary tracks is now limited
to 1 minute in order to prevent recording of endless
events.
MAIN Priority control of clock synchronization is now settable.
Positive- and negative-sequence currents from all ends
are now continuously calculated and displayed as
measured operating data (primary and per-unit values).
OL_RC, FT_RC Overload and fault recording now have a joint and
complete list of possible entries (merged list of all
previous signals).
In practice it became apparent that limitations with
regard to possible entries in both recording memories
would bring no advantages but make analyzing more
difficult, as both recording memories could be open at
the same time (e.g. a thermal overload situation could
lead to a loss of insulation which would cause a fault).
