Number, coded, used to measure the flow.
For example:
Varie 0-250 = integrated check valve (MMW) is closed.
1023 = integrated check valve (MMW) fully open.
This parameter is required in order to perform the correct procedure for switching off
the pump when the pressure reaches the nominal value required par. (72).
E.g.: The driver turns off when the measured flow (par 38) is lower than the set
appr. 1023
threshold (par 39). If 1023 is also set, the driver stop procedure does not consider the
flow. In this case the AQUONTROLLER version MMA procedure is used.
Note: if set 1023, MMW transforms to MMA
Delay time to enter the condition of "minimum threshold" (par.22), end of curve pump
20 operation. The pump remains stationary for the time set in par. (16) and attempts are
made to restart at the value set in par. (17).
In the presence of a fault, it displays the delay prior to entering the "No water" (par
Varie 42) alarm condition and increases the number of no-water alarms counter, par(24).
Non-return valve closed
Delay before entering the "No Water" alarm condition with non-return valve closed and
motor running at 50Hz.

The alarm trips when the pressure falls below the minimum threshold (par 22) but
measures zero flow (par 38).
Varie Frequency applied to the motor
Varie Voltage applied to the motor (proprietary unit of measurement: Umax=32767)
The delay prior to entering the Minimum threshold alarm condition (par 22) and flow
Varie
present is displayed. Moto runs at50Hz, non return valve open.
Varie Pump power input (Par 1).
When the delay elapses, Delta bar (par 53) checks the pressure value for the set time. If
1
it remains where it is or increases, the drive stops.
Nominal motor current of the motor (see the motor rating plate). The maximum power
4.5 of the AQUONTROLLER (see plate) must not be exceeded. For longer cable length
(>50m) the value can be increased for 10%.
Displays the total time on supply, expressed in proprietary units. 1 unit = 0.1 seconds.

After 65535 = 1,82 hours the par 50 is increased by one unit.
