Version Changes
CBF_x The parameter (056 007) has been renamed to CBF_1:
Function group CBF_1 without any changes in the
functionality.
The following parameters may now not only be set to
an explicit time value but also to “Blocked”:
●
CBF_2: Delay/fault beh. CB (022 227)
●
CBF_3: Delay/fault beh. CB (022 240)
●
CBF_4: Delay/fault beh. CB (022 254)
The startup criterion has been modified. After a CBF
startup the state of the general trip signal or the
external trigger signal are now no longer considered.
The CBF will then only reset if the current criterion is
met (current values to fall below I< with all three
phases) or the CB state is open.

Software
LOC
Bug fixing:
●
Using the function where the set password can be
made visible on the LC-display by pressing all four
arrow keys simultaneously during the start up of
the device is now also possible with the new local
control panel (with function keys).
PSS
Bug fixing:
●
The time tags for the following spontaneous
signals (according to the communications
protocol per IEC-60870-5-10x) and the entry in
the operating data memory did not match:
o
PSS: PS 1 active (036 090)
o
PSS: PS 2 active (036 091)
o
PSS: PS 3 active (036 092)
o
PSS: PS 4 active (036 093)
V<> Bug fixing:
After a warm restart the following setting was not
active:
V<>: tTransient PSx (076 029) = Blocked
Because of this, the following signals were issued when
undervoltage conditions were present:
●
V<>: tV< elaps. transient (042 023)
●
V<>: tV<< elapsed trans. (042 025)
