PERATION
not energized, to allow safely stopping the run (by press-
ing Run). After the power-fail restart pending delay is
completed, the power supply output will ramp up to the
setpoint value and the run will continue from that point.
Any number of power interruptions can occur during the
completion of a single run.
If a power-fail restart occurs during the running of a pro-
gram the FB3000 will complete the interrupted step, and
then advance to the next step in the program.

Programming

The FB3000 can store 9 programs, each containing 9
steps. A program step is a constant voltage, current,
power, or temperature setpoint with any associated limit
parameters, and most importantly a time and/or volt-hour
setting. When running a program step, after the time or
volt-hour limit is reached, the FB3000 will automatically
run the next program step (if there is one). After all pro-
gram steps are completed in a program the FB3000 will
shut down. Any sequence of control mode and
timed/volt-hour steps can be contained in a program.
Note that a program step can contain a zero for the time
and volt-hour parameters, in which case the FB3000 will
continue to maintain that setpoint indefinitely (just like the
setting had been run from MANUAL mode).
To enter programming mode from an operating screen,
cycle the control logic off and then back on by pressing
the gray ON/OFF key and selecting PROGRAM. The
FB3000 will display the program screen, which shows the
number of steps contained in the selected program. Use
the function keys to the right of the display to move
through the 9 possible programs. To run the program
starting from step 1, press the Run key. To edit a pro-
gram (including adding a first step to an empty program)
press the function key labeled EDIT. The FB3000 will dis-
play the step screen, which shows the parameters for the
selected step (except when the program is empty in
which case the FB3000 automatically starts entering the
first step as follows). Use the function keys to the right of
the display to move through the 9 possible steps. To run
the program starting from the selected step, press the
Run key. To edit a step press the function key labeled
EDIT. The FB3000 displays the mode selection screen.
