MENTOR 12 US SECTION 3: ADVANCED CONTROL – Page 68 ER’S MANUAL
• If you have selected FREQUENCY, a tag will appear which indicates that “the
ramp will be applied to all the channels in Freq. 1” and the indicators of all the
sources that are in Frequency 1. These icons are only indicators and you
cannot select them as they are already selected.
• When you have made your selection, press OK to confirm and return to the
configuration screen, or CANCEL to return to the configuration screen without
making any selection.
• On the configuration screen, following the “Signal 1” key there must be a tag
that indicates the parameter (Amplitude or Phase), the type of signal selected
(Voltage or Current) and the output sources that the ramp will carry out (c1,
c2, etc).
• If you have selected FREQUENCY, the tag indicates Frequency and that it is
applied to all the sources in FREQ. 1
• Enter the desired values to execute the pulse ramp on the data input windows
of the graphic. You must enter values for the magnitude (white-colored
window and in the relative unit) and values for the durations (blue-colored
window and in milliseconds).
• Enter this value using the rotary knob in the window that defines the initial
value of the magnitude (on the green line). Bear in mind that this value of the
magnitude will be the same as the value between intervals, too, that is, the
value corresponding to the pre-fault state.
• Enter the desired time value in milliseconds in the window that defines the
duration of the initial state (below the green line). It is recommended to select
a minimum value of 1 second (1000 ms) to permit the correct polarisation of
the relay. This duration is only applied to the state prior to the start of the
pulse ramp, not to the intervals between increases that are selected
independently.
• Enter the first pulse of the ramp in the window that defines the value of the
magnitude. This is the initial value of the ramp.
