Enab.
: Function enabling (No = Disable / Yes = Enable)
Trig
:
Selection of the Trigger command source (start recording):
Start
= Trigger on time start of protection functions
Trip
= Trigger on trip (time delay end) of protection functions
OnCmd
= On Asynchronous Force trigger command
REUserLg
=
On rising edge of “User Logic”
(see § “User Trigger
Oscillo”)
FEUserLg
=
On falling edge of “User Logic”
tPre
: Recording time before Trigger
tPost
: Recording time after Trigger
14.17.2 - Operation
In the options: “Trig = Start” and “Trig = Trip”, the oscillographic recording starts respectively when
any protection function starts operating or trip (provided the fu
nction was programmed “Enab = Yes”).
The “Oscillo” Function includes the wave Form Capture of the input quantities 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 event stored can not exceed ten (10 x 0.3 sec).
Any new event beyond the 3 sec capacity of the memory, cancels and overwrites the former records
(FIFO Memory).
