Figure 4-12: VOLTAGE SURGE/SAG SETUP Screen
The Voltage surge and sag screen shown in Figure 4-12 can be reached from the transient
screen as follows:
1. Scroll to the VOLT SURGE/SAG entry using the up and down cursor keys.
2. Press the ENTER key to bring up the VOLT SURGE/SAG screen.
The VOLT SURGE/SAG screen has several data fields. All data fields that are blank to the right
of the equal sign must be filled or an error message will occur when trying to leave this screen.
The EVENT # is the last data field to be filled. Entering the event data field will cause the display
to return to the TRANSIENT screen where a new selection can be made.
The VOLT/SURGE/SAG screen has the following fields:
START ø This field will show the start phase angle of the voltage transient
in degrees. Only one start phase angle per transient sequence
is allowed. The start phase angle must be in the first transient
event in the list. The start phase angle is not valid for DC
transients. If no start phase angle is required, this field can be
set to RANDOM by pressing the BACKSPACE (<-) key on the
decimal keypad.
GO TO VOLT This field will set the voltage level during the transient duration
in volts
DUR SCALE Duration scale default is time in seconds. Use the Shuttle knob
to select CYCLES if desired. Note that durations expressed in
cycles may cause rounding errors if the period of the selected
frequency setting is not an integer number of mss. Thus, for 50
Hz applications, no rounding errors occur but for 60 Hz, the
16.66¯ ms period will cause a rounding error when converted.
The Duration scale selection affects both the DURATION and
END DELAY parameters.
DURATION Duration is the time the output voltage level will dwell at the GO
TO VOLT level. The DUR SCALE defines the time scale of this
parameter in CYCLES or SECONDS
END VOLT This is the output voltage level at the end of the transient
EVENT and after a time specified by the DURATION
END DELAY This is the time delay the voltage level will stay at the END
VOLT level before it proceeds with the next transient event or
completes the transient.
FUNCTION This field can be used to select the wave shape to be used
during this step of the transient sequence. Each step can use a
different wave shape from the available library of 50 user-
defined waveforms or the three standard waveforms. The
output wave shape changes upon entry into each step and
remains in effect for the duration of the step. The default wave
shape is always the SINE (sine wave).
