CHARACTERISTICS
Oscillography
Trigger Setup
Following parameters, available inside the Set \ Oscillography \ Trigger Setup menu, are user-pro-
grammable:
Pre-trigger time and Post-trigger time.
Element pickup trigger; the information recording starts when a state transition on any protec-
tive element occurs if the parameter is set to ON.
Trigger from outputs; the information recording starts when a state transition on the selected
output relay occurs if the parameter is set (K1...K6).
Binary input trigger; the information recording starts when a state transition on the selected
binary input occurs if the parameter is set to ON.
Trigger from inputs; the information recording starts when a state transition on the selected
binary input occurs if the parameter is set (IN1...INx).
80% Buffer alarm; when the 80% of the buffer space is reached an alarm may be issued if the
parameter is set to ON.
Set sampled channels
The desired sampled quantities may be select inside the Set \ Oscillography \ Set sampled channels
menu (u

Set analog channels
The desired sampled quantities may be select inside the Set \ Oscillography \ Set analog channels
menu.
Everyone of twelve analog channel may be associated to one of the selected measures (f

).
Set digital channels
The desired digital quantities may be select inside the Set \ Oscillography \ Set digital channels
menu.
Everyone of twelve digital channel may be associated to one of the selected I/O signal (K1... K6, K7...
K10, IN1, IN2, IN3...IN42
[2]
).
Note 1 The 26 menu is available when the MPT module is enabled
Nota 2 The output relay K7...K10 and binary input IN3...IN42 states is meaningful when the I/O circuits are present (MRI and MID16 modules)
