Lack of Water
This error message will be displayed when a switch has indicated that the incoming water pressure
or water level in a suction tank falls below the required NPSH of the pump. If suction conditions
appear to be correct, check the pressure switch or float switch to make sure it is operating proper-
ly. When the suction conditions have returned to normal, the pump will restart automatically. This
message will also appear if terminals 6 and 7 on terminal block X1 are not bridged.
Conveyor Control (Value Range Control)
The drive is not able to obtain the minimum required value set in the conveyor limit setting. Look
for potential reasons for the low signal or lower the “CONVEYOR CONTROL” or increase the
“DELAY TIME” settings.
