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 o 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 o.
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 o 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.
