CHECKING THE DIRECTION OF ROTATION OF THE MOTOR (PUMP 1 ROTATION) 

For surface pumps

 (see fig. below): switch the system to TEST mode, start it by pressing START, and look to 

see whether the motor fan is turning in the direction indicated on the pump body. Stop the system by pressing 
STOP.

If the direction of rotation does not coincide, 

switch it over by means of the PUMP 1 ROTATION parameter (see

For  submersible  pumps

 

(see  fig.  below)  the  system  must  be  placed  in  WORK  mode;  start  the  system  by 

pressing  START,  with  a  connected  unit  open;  DGBOX  will  take  the  system  pressure  to  that  of  set  P1.  Once 
operating speed has been achieved, read and record the operating frequency to maintain the pressure of set 
P1.

Now reverse the direction of rotation by means of the PUMP 1 ROTATION parameter as indicated in the above 
example  for  surface  pumps,  repeat  the  starting  operation  and  again  record  the  operating  frequency  to 
maintain the SET pressure. 

The correct direction of rotation is that which calls for the lesser frequency to maintain the 
SET pressure.
