and/or volt-hour setting. When running a program step, after the time or volt-hour limit is
reached, the FB1000 will automatically run the next program step (if there is one). After all
program steps are completed in a program the FB1000 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 FB1000 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 FB1000 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 program (including adding a first step
to an empty program) press the function key labeled EDIT. The FB1000 will display the step
screen, which shows the parameters for the selected step (except when the program is empty in
which case the FB1000 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
FB1000 displays the mode selection screen. Select a constant mode of operation by pressing the
appropriate function key located to the right of the display. To switch between
volts/current/power and time/volt-hours, press function key F1. To change a parameter, press the
function key located to the right of the display, next to the parameter you wish to change. The
FB1000 will allow a new value to be entered using the keypad numeric keys. Press the function
key labeled "Enter" to complete the new setting. Press Clear to erase previous keystrokes. Press
Exit to cancel entering a new value. The FB1000 will not accept any parameter outside of the
allowed range. Press Clear to re-enter an appropriate value. When all the parameters of the step
are as desired, press Exit to return to the step screen. The newly entered parameters will be
displayed in the selected step. To add a step after the selected step press the function key labeled
ADD. Enter parameters for the step as for EDIT, pressing Exit when complete.
To delete a program or step, press the Clear key from the program or step screen as desired. After
confirmation the FB1000 will remove the selected program or step from memory.
