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 not run dry; functioning under these conditions (even for a short time) irreparably damage the
pump itself. For this the control system intervenes after about a minute (usually sufficient time for water loading
pump during the initial service) with an alarm, stopping the pump as described in Chapter 2.
Make the air purging on the pump.To prevent the entry of impurity in the first put in service, in case of pumping
of drinking water, run an abundant rinsing and disinfecting.
The motor, can reach temperatures above 100 ¡C. Danger of burns to simple contact with the
motor.
6.1 First Inverter Using – Self Regulation 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 Ò+Ó and Ò-Ò buttons, finally confirming with
ENTER.
·
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 for the
regulation of the stop for closed output. During the Check the display show ÒEXECUTING CHECKÓ; 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 User’s check after Inverter setting
Check the pump stop for Minimum Flow
: At the first installation open the output on the pump flow, press
START, wait a few seconds for the plant go to pressure set, then close the output flow (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
constructor. The absolute stop power value is showed at regular times on display at the top-central position (see
fig. 10).
Check pump dry-working
: After installation, if itÕs possible, close the suction/intake of pump in order to
simulate a run dry situation; After a time of about 40 seconds (or the set delay time), the pump should stop,
displaying ÒDRY WORKING". If, after this time, the pump does not stop you must set into ADVANCED
FUNCTIONS Ð PRESSURE CONTROL setting a higher value of the parameter COSFI LIMIT (by default set to
0.5). Save data after modifying.
