70 Operating the Pump
Status description
ƒ System (green) – The controller is switched on and
power is available. In low-power conditions, the light
may show even if there is not enough power to run
the pump.
Flashing indicates the pump is not running due to
settings, e.g. a timer set up with PumpScanner.
ƒ Pump (green) – Pump is running. The sequence of
flashing indicates pump speed (RPM). RPM can be read
by the flashing sequence of the Pump ON LED:
LED signal
LED On
1 flash
2 flashes
3 flashes
4 flashes
5 flashes
Motor frequency
[Hz]
> 0
> 25
> 30
> 35

> 45
ƒ Pump (red) – An error has occured, please check with
PumpScanner for details.
Flashing indicates that the controller's thermal protec-
tion was triggered due to a too high temperature. The
controller has reduced the motor speed or stopped the
pump. It will automatically speed up or restart after
cooling down.
ƒ Source low (red) – The water source has dropped
below the level of the low-water probe or the water
sensor has detected air in the suction pipe. After the
water level recovers or the suction pipe has been re-
filled with water, the pump will restart after a delay of
20 minutes. Flashing indicates that the controller has
stopped due to a "SOURCE LOW" incdent detected
earlier. The number of flashes indicates the number of
incidents (up to three). Toggle the ON/OFF switch to
reset this indicator.
ƒ Remote switch (red) – A pump shutdown was trig-
gered by the remote switch wired to terminals 3 and 4.
ƒ Remote switch (red light flashing) – An external
power error with the SmartPSUk2 has occurred. Please
check with PumpScanner for details.
