Number of possible driver restarts following alarms relative to driver. When this value is
reached, the driver stops and displays the fault. When this value is reached, turn the
driver off and back on again. In the event of a short circuit, reset the relative short
circuit number

System pressure value below which “minimum threshold”,
The intervention is delayed by the time set in par. (40).
MMW Version:
Minimum threshold with this flow and the non-return valve, integrated, is open. In this
condition the engine is running at 50Hz and is in working condition outside curve.
MMA Version:
Minimum threshold: the alarm occurs when the system pressure does not exceed the
minimum threshold set Par (22).
In the presence of alarm threshold the pump is stopped and the number of attempts
depends on the par. (17).
