Water detection via safety oat
If the water level is high enough to activate the level sensor, i.e. HIGH=1, and IN1 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.
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.
In this operating mode, the second pump can be activated with the HELP SET function, even when it is not enabled by the
safety oat (at IN2).
Inputs IN1 and IN2 have no eect on switching o the pump or both pumps (if there are two). Any pumps that are running
will be switched o and inputs IN1 and IN2 will be disabled if the water level drops enough to disable the high level sensor
(COM-MAX), i.e. HIGH=0.
Pressing the ESC button shows the input states (IN1 - IN2 and LOW - HIGH) on the alphanumeric part of the display.
