Displays the total time on supply, expressed in proprietary units.
Varie
1 unit = 1.82 hours (400=1 month, 4800=1 year).
Displays the total operating time, expressed in proprietary units. 1 unit = 0.1 seconds.
Varie
After 65535 = 1,82 hours the par 50 is increased by one unit.
Displays the total operating time, expressed in proprietary units.
Varie
1 unit = 1.82 hours (400=1 month, 4800=1 year).
Delay during which the inverter attempts to stop. Enabled when pressure and
5,0
frequency are constant. Connected with parameter 47.
Maximum power input of pump with no flow. Parameter used to monitor pump
599
operation, particularly in the dry-running condition.
If ON, the driver is enabled to operate via a digital external command (contact open =
0000
inverter standby).
Set the time, over 24 hours, the pump must be stopped. Default 45 minutes. If this
29000= time is exceeded the display shows "leaks". In the sixth event (fixed number), the drive
48min stops completely. Must be turned off, check the status of the system by eliminating the
losses, if any. Parameter needed to diagnose problems of the drive to stop.
Within 24 hours, shows the time in which the engine is stopped. Parameter used to
Varie
diagnose the presence of leakage.
Counts the number of times the continuous pump operating time exceeds the hold
time t0 Pump Off (par 58). By default, so as not to increase the number of leaks, the
Varie pump must not operate for at least 54 mins within a 24 hour timescale. If the "leaks"
message appears, check whether there are leaks in the system or check times and
settings.
Zero-setting the power reading made by the driver (par 46). Parameter only available in
90
multiple pump systems.
Displays the time elapsed (timer) in the alarm and no water or insufficient pressure.
In the absence of flow with a frequency greater than 45Hz, the timer is incremented.
Varie
MMA Version: power less than the value set in par (54) and higher frequency at 45Hz.
MMW Version: Flow valve closed and a frequency above 45Hz.
50 This parameter must be set to default value "50"
40 Phase-phase or phase-ground short circuit counter. Default value 40.
