Set parameter rC
1-2) Prime the pump and ensure that there are no air
bubbles in pipelines. Check that suction and any filters are
not obstructed Check that the pipeline from the pump to the
A.D. is not damaged or leaks significantly.
3) Check the direction of rotation, parameter rt
1) Check the type of connection; star or delta.
Check the direction of rotation, parameter rt
Check that the motor does not absorb current levels
exceeding the max. supply of A.D.
2) Check that the impeller or motor is not blocked or
obstructed by foreign bodies. Check the motor connection
phases
1) Set rC with the current according to the type of
connection (star or delta) as stated on the motor dataplate.
