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 ms. 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.
