[. . . ] If the problem persists after checking the process EC and fertilizer supplies, check panel S57 (SET PID PARAMETERS) to insure that the control algorithms are correct. Program not set correctly The minimum conditions that have to be set in order to have the program working are: - At least one sector has to be set (the irrigation value is different from zero) - Priority set between 1 and 5 - Sector / group set between 1 and 8 - At least one Start condition has to be selected - All the time constrains have to be met (see panels S 31 and S 32) Incorrectly displayed sensor values Recalibrate sensors. If the alarm output does not work when the correspondent led is on, check the fuse to the right of the alarm connector. If the rapid valves that control the pH, conductivity and filters do not function when the correspondent led is on, check the fuse to the right of the fast valve connector. [. . . ]
