6. STARTING AND PROGRAMMING
The starting and programming operations must be executed exclusively by experienced and
qualified staff. Use the appropriate equipment and protections. To supply voltage on the Inverter
verify that the Inverter box is completely closed, after having carefully followed all the instructions
wiring above.
The pump can’t operate in dry running; functioning under these conditions (even for a short time) irreparably damage
the pump itself. For that, the control system reacts after 40 seconds with an alarm, stopping the pump.
Make the air purging on the pump.
6.1 First Inverter Starting – Check procedure
• Press START and set the nominal current absorbing for the phases connection in use (see 5.3);
• Press START and on rotation direction request, maintaining pulsed the START button until the reading of
electrical data measures and select the direction (0,1) with “+” and “-“ buttons, finally confirming with
ENTER, then exit from menu with ESC.
• Be sure that the pump is fully of water and close completely the outlet of the pump.
• Pressing START for the Self-Regulation Check for the registration of the curve of the pump. During the
Check the display show “EXECUTING CHECK”; at the end of the check the Inverter automatically save
data and the pump may work normally.
During Self-regulation Check the pump may arrive at the nominal velocity, with maximum pressure.
If you need, limits the maximum pressure previously (Pump Data).
6.2 Installer checks after Inverter setting
6.2.1 Check the minimum flow protection (for the absolute pressure control): At the first installation open the
delivery on the pump flow, press START, wait a few seconds to reach the pressure set-point, then close the pump
delivery valve (slowly) and make sure that the motor stops (after a few seconds) showing on display "MINIMUM
FLOW". In case the motor does not stop you must select MOTOR DATA - POWER STOP and set a higher value
than the default (103%) set by the factory. The absolute stop power value is showed, at regular times, on display at
the top-central position.
6.2.2 Check the dry-working protection: After installation, if it’s possible, close the delivery of the pump in order
that the pump run dry; After a time of about 40 seconds (or the set delay time), the pump should stop, displaying
“DRY WORKING". If, after this time, the pump does not stop, you must enter into ADVANCED FUNCTIONS –
PRESSURE CONTROL, setting a higher value of the parameter COSFI LIMIT (by default set to 0.5). Save data
after modifying.
