Water detection via level sensor
If the water level in the collection tank is low enough to deactivate both level sensors (tank empty), i.e. LOW=0 and
HIGH=0, and IN1 is closed with a NO voltage-free contact (in the accumulation tank), 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.
In this operating mode, the second pump can be activated with the HELP SET function, even when it is not enabled by the
safety float (at IN2).
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, and the display indicates that there is no water in the accumulation tank (NO WATER).
Moreover, if the water level in the collection tank rises enough to activate the high level sensor (COM-MAX), i.e. HIGH=1,
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.
