4.3 Basic Operation
Program Mode: The Program mode is used to program the parameters of the RS-3000.
Press the PRGM key to enter the programmable parameter sequence. The PRGM LED will
illuminate and flash while the RS-3000 is in Program mode.
Use the INC and DEC keys to adjust values for each parameter. Step through the
parameters by pressing the PRGM key.
Current Maximum: Use the INC and DEC keys to adjust the maximum current value
within a range of 0-600 Amps for parallel-wired outputs or 0-300 Amps for series-
wired outputs.
Ramp Minutes: Use the INC and DEC keys to adjust the ramp time value within a
range of 0.0-99.9 minutes.
Ramp Current: Use the INC and DEC keys to adjust the ramp current value within a
range of 0-600 Amps for parallel-wired outputs or 0-300 Amps for series-wired
outputs.
Beeper: Use the INC and DEC keys to toggle the beeper on or off.
Host Communication Baud Rate: Adjustments to this parameter are needed only if
the RS-3000 is controlled using a PC. See the RS-3000 manual for further
information.
Ramp Mode: The Ramp mode is used to ramp the power supply current up from zero to a
preset level, and then hold at that level. Ramp mode is selected by entering a non-zero
time in the “Ramp Minutes” parameter.
When the RS-3000 is running in Ramp mode, the small display shows time remaining,
which counts down to zero, alternately with power supply output (in kilowatts.) The Kw
indicator illuminates while the power value is displayed, and the MIN indicator illuminates
while the time-remaining value is displayed. The large display shows ramp current.
When the RS-3000 finishes ramping it will automatically switch to Manual mode and
maintain the current level until the STOP key is pressed. When Manual mode begins, the
small display will switch to show time elapsed (counting up from zero).
The process may be stopped during Ramp or Manual mode by pressing the STOP key.
Manual Mode: The Manual mode allows manual control of the current level via the INC
and DEC keys. Manual mode will be entered and the MAN LED indicator will illuminate
when the Start key is pressed, if the value of the Ramp Minutes parameter is zero.
When the RS-3000 is running in Manual mode, the large display shows current in Amps.
The small display shows time elapsed since the Start key was pressed alternately with
