3.12 - CBMng – Close Breaker Manage
FuncEnab → No Param No Parameters
Options → No Param No Parameters
TripLev → No Param No Parameters
Timers → tcmd 0.10 s (0.10  5.00) step 0.1 s
→ tC 0.10 s (0.10  5.00) step 0.1 s
Description of variables
tcmd : C/B closing output command duration
tC : Maximum admissible delay for detection of status signal after C/B operation.
3.13 - Osc - Oscillographic Recording
FuncEnab → Enable [Disable / Enable]
Options → Trg Trip [Disable / Start / Trip / Ext.Inp.]
TripLev → No Param No Parameters
Timers → tPre 0.30 s (0.10  0.50) step 0.1 s
→ tPost 0.30 s (0.10  1.50) step 0.1 s
Description of variables
FuncEnab : If disable the function is disactivated
Trg : Disab = Function Disable (no recording)
Start. = Trigger on time start of protection functions
Trip = Trigger on trip (time delay end) of protection functions
Ext.Inp. = Trigger from the Digital Input D3
tPre : Recording time before Trigger
tPost : Recording time after Trigger
When the
option “Start” or “Trip” is selected:
The oscillographic recording is started respectively by the “Time Start” or by the “Time End” of any of the
functions that have been programmed to Trigger the Wave Form Capture (I>, I>>, IH, Io>, Io>>, IoH).
The “Osc” Function includes the wave Form Capture of the input quantities (IA, IB, IC, I N) and can totally
store a record of 3 seconds.
The number of events recorded depends on the duration of each individual recording (tPre + tPost).
In any case the number of events stored cannot exceed ten (10 x 0.3 sec).
Any new event beyond the 3 sec capacity of the memory, cancel and overwrites the former records (FIFO
Memory).
