Pressure Control
1. Pressure Hysteresis
[BAR]
2. Max Pressure *(not
for 2.2M)
3. *(2) Dry working
stop delay [s]
4. *(3) Dry working re-
start time [min]
5. Pipe filling delay [s]
*(not for 2.2M)
6. Filling Pressure limit
[BAR] *(not for
2.2M)
7. *(4) Minimum flow
stop delay [s]
8. *(5) Minimum flow
restart delay [s]
9. Alarm restart delay
[s] *(not for 2.2M)
10. *(6) Dry operating
PF limit
11. *(7) Enable OFF
Stop Delay (from
V.11.08)
12. *(8) DP-flow
reduction power [%]
13. *(9) DP-flow
reduction max value
[%]
14. *(10) Alternating
time [min]
15. *(11) Intake
pressure
1. Pressure control hysteresis
2. Max Pressure *(not for 2.2M)
3. *(2) Dry working stop delay time
for pump filling
4. *(3) Dry working re-start delay
time after firsts 5th times; after
the 5
th
, the Inverter require a
manual re-start (STOP +
START) *(not for 2.2M)
5. Pipe filling time at the minimum
speed when the pressure
measured during the motor
starting is lower than the Filling
Pressure Limit (next point) *(not
for 2.2M)
6. Pressure limit for the reduces
speed motor starting, during pipe
filling
7. *(4) Delay time for the Minimum
flow protection stop (only for the
Absolute pressure control)
8. *(5) Delay time for the motor re-
start after the minimum flow stop
– (only for the Absolute Pressure
control);
9. Delay time to re-start the motor
after a protection stop
10. *(6) When the Power Factor
undertake this value, the pump
stop for dry operating protection
11. *(7) Switch-off delay after EN
contact opening
(from V.11.08)
12. *(8) Power value limit for the
reduction of the Differential
pressure
13. *(9) Differential Pressure
reduction when the power is
under the limit of previous point
14. *(10) Time of the alternating
starting priority of two or more
pumps in Master-Slave group
mode
15. *(11) Intake pressure setting:
make use to avoid over-
elongation with intake pressures
over 2 Bar; the minimum
reference pressure will be the
same to the intake pressure +
0.5 Bar + hysteresis.
