CYCLIC RESET FOR DRY RUN
Setting the N value stops automatic restarts after the fourth attempt,
while setting the S value after the fourth attempt resumes the restart cycle
starting from the fourth time that is set to an infinite time.
The panel's dry run protection system restarts based on the programming
time settings, and resets the restart cycle whenever the system detects
the presence of water for more than 10 seconds.
ANALOG SIGNAL ACTIVATION
This parameter allows the input to be enabled with analog signal.
(with analogue signal enabled, if sensor C and MAX fails, it functions as
emergency stop and G/P1 as emergency start of pumps).
TYPE OF ANALOG SIGNAL
This parameter allows the type of panel input analog signal to be selected
2-wire active sensor:
0-10V: Terminal "A/B" = signal; Terminal "-" = negative;
4-20 mA: Terminal "+" = positive; Terminal "A/B"= signal;
3-wire active sensor:
0-10V: Terminal "+" = positive; Terminal "A/B" = signal; Terminal "-" =
negative;
4-20 mA: Terminal "+" = positive; Terminal "A/B"= signal; Terminal "-" =
negative;
ANALOG SIGNAL UNIT OF MEASURE
This parameter allows the unit of measure of the panel input analog signal
to be selected:
By selecting "bar", the panel works in PRESSURIZATION mode: the motors
will be enabled when the analogue signal decreases compared to set point
value (set point higher than start threshold).
