After finishing these settings, the following things can be demonstrated:
· Program 1 started
by time.
Allows verifying the: start times, set valves and irrigation time.

Starts program 3 (ext. tank 03) and immediately starts program 2 (ext. tank 02). Program 2 has
a high priority and should be activated (program 3 goes in suspend state). After that, program
2 is finished and program 3 is reactivated.
· The alarms
Generates a low level in the mixing tank (simulator).
The ALARM led will blink and this setting is available on panel C25.
Modify the pH 1 sensor value. When the value is out of the set range, a new alarm is generated
(C25). Modify the pH2 sensor value to obtain a difference between pH1 and pH2 bigger that
