38 Measured Flux MMW R N 0 1023 Varie
Number, coded, used to measure the flow.
For example:
0-250 = integrated check valve (MMW) is closed.
1023 = integrated check valve (MMW) fully open.
39 Treshold Flux MMW RW N 0 1023 appr. 1023
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
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
40 TimeMinThreshold

RW sec 1 1200 20
Delay time to enter the condition of "minimum threshold" (par.22), end of curve pump
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
42) alarm condition and increases the number of no-water alarms counter, par(24).
Non-return valve closed
42 LackOfWaterTime MMW RW sec 1 1200 25
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).

When the delay elapses, Delta bar (par 53) checks the pressure value for the set time. If
it remains where it is or increases, the drive stops.
