GENERAL INFO C01

This panel displays the following information starting from top left:
Fertigation Controller Functional State (top left corner)

When the controller is running it can be in one of the following states:
INITIALIZATION, STOP, WORK, BLOCK. When the Fertigation Controller is
first powered on the first state is INITIALIZATION. In this state the unit
performs internal tests. In STOP state all programs are suspended. Under
normal conditions the functional state is WORK. In the WORK state all
irrigation and fertilization programs are executed. If an alarm occurs the
Fertigation Controller enters the BLOCK state until the alarm condition is
corrected. The user can customize the alarm management system behavior
using setting panels S 40, S 41 (pH and EC CONTROL) and panel S 52
(ALARM BEHAVIOR).

Anomalies (top right corner)

The anomalies counter represents the number of alarms triggered since
the last reset of the counter. This counter can be customized and cleared
along with all system statistics via setting panel S 61 (ERASE STATISTICS).
