A new record may automatically overwrite an older record if
TRIGGER MODE
is set to “Automatic Overwrite”.
Set the
TRIGGER POSITION
to a percentage of the total buffer size (e.g. 10%, 50%, 75%, etc.). A trigger position of 25% con-
sists of 25% pre- and 75% post-trigger data. The
TRIGGER SOURCE
is always captured in oscillography and may be any
FlexLogic™ parameter (element state, contact input, virtual output, etc.). The relay sampling rate is 64 samples per cycle.
The
AC INPUT WAVEFORMS
setting determines the sampling rate at which AC input signals (i.e. current and voltage) are
stored. Reducing the sampling rate allows longer records to be stored. This setting has no effect on the internal sampling
rate of the relay which is always 64 samples per cycle, i.e. it has no effect on the fundamental calculations of the device.
When changes are made to the oscillography settings, all existing oscillography records will be CLEARED.

PATH: SETTINGS PRODUCT SETUP
OSCILLOGRAPHY
DIGITAL CHANNELS
A
DIGITAL CHANNEL
setting selects the FlexLogic™ operand state recorded in an oscillography trace. The length of each
oscillography trace depends in part on the number of parameters selected here. Parameters set to “Off” are ignored. Upon
startup, the relay will automatically prepare the parameter list.
c) ANALOG CHANNELS
PATH: SETTINGS PRODUCT SETUP
OSCILLOGRAPHY
ANALOG CHANNELS
An
ANALOG CHANNEL
setting selects the metering actual value recorded in an oscillography trace. The length of each oscil-
lography trace depends in part on the number of parameters selected here. Parameters set to “Off” are ignored. The
parameters available in a given relay are dependent on: (a) the type of relay, (b) the type and number of CT/VT hardware
modules installed, and (c) the type and number of Analog Input hardware modules installed. Upon startup, the relay will
automatically prepare the parameter list. A list of all possible analog metering actual value parameters is presented in
Appendix A:
FlexAnalog Parameters
. The parameter index number shown in any of the tables is used to expedite the
selection of the parameter on the relay display. It can be quite time-consuming to scan through the list of parameters via the
relay keypad/display - entering this number via the relay keypad will cause the corresponding parameter to be displayed.
