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
5
driver off and back on again. In the event of a short circuit, reset the relative short
circuit number
Counts the number of restarts performed by the driver following alarms. To reset this
0
value, turn the driver off and back on again.
8 Proportional coefficient of PID regulator
Delay between motor starts following hydraulic alarms, such as: no water, insufficient
10
pressure.
5 Number of possible driver restarts following hydraulic alarms.
Counts the number of motor restarts following hydraulic alarms, such as: insufficient
Varie
pressure, no water.
Varie Average direct current measured on the DC Bus circuit powering the unit.
Varie Counts the number of times the measured pressure exceeds twice the set point.
Minimum motor start and stop frequency. Frequency at which the driver starts
10
operating (both when starting and stopping) without using ramps.
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.
0.8 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).
Displays the pressure reference PID. This parameter may vary in certain operating
Varie conditions of drive (acceleration, deceleration,stop procedure).., value can be different
from the nominal value/setpoit par(34).
Number of pump start attempts following no water alarm. By default, one start attempt
24
is performed every 50 mins.
Varie Counts the number of times the no flow condition is present.
