4.6.3.8 TRANSIENT WFs (cont’d)
If
DISABLED
, the RMS calculation of substituted waveforms does not occur. The amplitude of
all waveforms used in the transient will then be based on the system gain factor for each phase,
as calculated for the Program which contains the transient. This facilitates constant-amplitude
transients, such as partial cycle dropouts or sub-cycle spike transients. To have the transient
waveforms track the amplitude of the Program steady-state values, the base waveforms used in
all segments must be consistent.
EXAMPLE: If a 10% spike transient waveform is desired, the base sine wave was copied at
90% to allow margin for the spike (see 4.6.2.2). The TRANSIENT WFs setting should be
RMS=DISABLED and the Program must use a sine wave copied at 90% but without the spike.
The Program will calculate the system gain to create the programmed voltage using the 90%
waveform and the transient will then be executed using that gain, thereby maintaining sine wave
continuity.
4.6.3.9 INITIAL VOLTAGE
Selecting INITIAL VOLTAGE from the General Setup 2 menu (
fn
,
3
,
7
,
3
) allows you to specify the initial
power up output voltage amplitude.
From any METER display (V/I, AMPS or POWER), press the
fn
key to enter SETUP MODE.
From the SETUP display, press
3
to enter GENERAL SETUP.
From the GENERAL SETUP 1 display, press
7
to enter More Options
From the GENERAL SETUP 2 display, press
3
to enter INITIAL VOLTAGE.
INITIAL VOLTAGE SETUP:
VOLTAGE=0
(Press +/- Key to Toggle Selection
(Press ENTER or EXECUTE to Exit
VOLTAGE=
:
0
or
LAST EXECUTED.
If
0
is chosen, the unit will set the output voltage to 0
regardless of output voltage prior to turning the unit off. Choosing
LAST EXECUTED
means the power source will automatically power on with the output voltage setting that
existed prior to turning the unit off. The output relay will always be open at power-up
unless an “Auto-Start” option has been installed.
NOTE:
The default factory setting for INITIAL VOLTAGE is 0.
