Never run the pump for more than five
minutes with a closed gate valve.
Starting pump
Press the button
status from
STOP to run. The pump starts up
with the acceleration ramp set to reach the wished
set-point.
When the motor start turning, check the
direction of rotation.
If the pump has been primed correctly, after a few
seconds the pressure will begin to increase on the
display.
If, after a few seconds of operation the pressure
remains at 0.0 bar, stop the pump by selecting
(stop) as priming has not been carried out correctly
and the pump is idling. Re-prime the pump and
repeat the starting up procedure.
12.1. Cascade mode plant starting
Check that all the cascade mode parameters are
with the desired values, the parameters that can
change the cascade mode operation are:
PC14 / PP13
Cascade
pressure setup.
PC15 / PP14
Cascade mode restart delay.
PC16 / PP15
Cascade mode fall pressure
limit setup.
To do the plant starting follow the instructions under
paragraph 12.
12.2. Inversion of the direction of rotation
To change the direction of rotation of the motor push
the button
(menu) and then with the button
(plus) or
(minus) move up to the programming
parameter UP. Confirm with
the button
(plus) or
parameter UP04, confirm with
pushing of the button
confirm with
(enter). To exit the program, push
(menu) until you arrive on the basic display,
when you are out from the setup mode the icon
disappear.
12.3. Vessel pressure
One the set-point pressure has been
chosen, the pre-charge pressure of the
vessel needs to be changed, slightly lower
than the pump startup pressure.
More precisely:
For single pump Constant Pressure mode:
Vessel Pre-charge pressure: UP06-PC09-0.4
For single pump Proportional Pressure Mode:
Vessel Pre-charge pressure: UP06-PP08-0.4

(plus) change the value,
For Multi-pump Constant Pressure mode:
Vessel Pre-charge pressure: UP06-PC16-0.1
For Multi-pump Proportional Pressure mode:
Vessel Pre-charge pressure: UP06-PP15-0.1
13. Use of megaohmeter
OFF
Measuring the resistance of an installation
incorporating the frequency converter is not allowed,
because the electronics may be damaged. If it is
necessary, disconnect the frequency converter and
use the megaohmeter directly on the terminal box
of the pump.
14. Maintenance
ON
Inspect the tank preloaded pressure of the delivery
vessel periodically.
