8.13. Float Backup - Off Level - Function 33
When a Discrete Input programmed for “Float Backup - Off Level” closes, the Float Backup logic
will be armed and made ready to latch in one pump call for each of the “Float Backup - 1st,
2nd, 3rd, 4th On Level” inputs that close.
As the “Float Backup - 1st, 2nd, 3rd, 4th On Level” inputs open, the pump calls remain latched
until the Off Level input also opens, then the latch is broken on all the pump calls, and the
pumps are turned off.
Note: For a two float backup system, the “Float - Backup - 1st, 2nd, 3rd, 4th On Level” inputs
may be replaced with the High Level input for the Pump Down mode, or the Low Level input for
the Pump Up mode.
See Page 55.
8.14. Float Backup - 1st On Level - Function 34
When a discrete Input programmed for “Float Backup - 1st On Level” closes, the Float Backup
logic will issue one pump call assuming that the “Float Backup - Off Level” is closed. See Page
55.
8.15. Float Backup - 2nd On Level - Function 35
When a discrete Input programmed for “Float Backup - 2nd On Level” closes, the Float Backup
logic will issue one pump call assuming that the “Float Backup - Off Level” is closed. See Page
55.
8.16. Float Backup - 3rd On Level - Function 36
When a discrete Input programmed for “Float Backup - 3rd On Level” closes, the Float Backup
logic will issue one pump call assuming that the “Float Backup - Off Level” is closed. See Page
55.
8.17. Float Backup - 4th On Level - Function 37
When a Discrete Input programmed for “Float Backup - 4th On Level” closes, the Float Backup
logic will issue one pump call assuming that the “Float Backup - Off Level” is closed. See Page
