DESCRIPTION
Sets the differential between the pressure
selected (SET PRESSURE) and the effective
restart pressure
Sets the nominal frequency of the motor.
The set value must be the same as that of
the nameplate of the motor
Sets the minimum functional frequency
Sets the maximum functional frequency.
ATTENTION: the increase in the maximum
frequency compared to the nominal
frequency can cause strong overloads of
the motor.
Sets the delayed stop of the pump in
conditions of dry running.
ATTENTION: too high values of a delayed
stop can damage the pump
Sets the minimum value of the power
factor below which the inverter stops the
pump to stop it running dry.
In order to define the minimum value of
the power factor read the value with the
inflow completely closed and
as a margin subtract 3 points.
Sets the delay in stopping the pump in
conditions of a power factor below the
minimum one. The delay must be as short
as possible as the pump must never run
when dry.
Setting the value at "0" one excludes the
control of dry running with COSFI
Sets the interval between two successive
automatic attempts to restart after a stop
due to dry working.
Setting the value to"0" one excludes
automatic attempts to restart
Sets the delay in stopping the pump in
conditions of no flow
