Water detection via level sensor
If the water level is high enough to activate both level sensors, i.e. LOW=1 and HIGH=1, and IN1 is closed with a NO volt-
age-free contact, either one pump or the other (if there are two) starts running according to the alternating logic.
If IN2 is also closed with a NO voltage-free contact, the other pump starts running (if there are two).
If, instead, IN1 is not used, when IN2 is closed with a NO voltage-free contact, either one pump or the other (if there are two)
starts running according to the alternating logic, and the pump that was off starts running few seconds later.
If inputs IN1 and IN2 are enabled at any time by opening a NO voltage-free contact, one or both pumps (if there are two)
are switched off.
In any operating state, if the water level drops enough to deactivate both level sensors (COM-MIN and COM-MAX), i.e.
LOW=0 and HIGH=0, any pumps that are running will be turned off and inputs IN1 and IN2 will be disabled.
Pressing the ESC button shows the input states (IN1 - IN2 and LOW - HIGH) on the alphanumeric part of the display.
