3.11 Indicator LEDs
The pump has ve indicator LEDs. Refer to Figure: Motor controller status informaon on
page 46.

Indicator LEDs
LED Descripon
Normal LED
The green LED comes on when the rotaonal speed of the
pump is more than the normal speed seng, irrespecve of
the acceleraon or deceleraon of the pump. The LED is
duplicated at the sides of the pump.
Status LED
The yellow LED ashes with a 50% duty cycle at the rotaonal
frequency of the pump motor. At high speeds it is connuously
on. The LED sets to o when the rotaonal speed is very low or
stopped. If the next service is available, the LED ashes in a
sequence to show which service operaon is necessary. Refer
to Fault nding on page 86. The LED is duplicated at the sides of
the pump.
Alarm LED
The red LED ashes in a sequence to show an error code if a
FAIL condion is prevenng the pump operaon. The error
codes can be used for the fault nding as given in Fault nding
on page 86. The LED is duplicated at the sides of the pump.
Serial
Communicaons
Receive (Rx) LED
The yellow LED ashes when the acvity is sensed on the serial
link receive line. It can be used for the fault nding the serial
link.
Serial
Communicaons
Transmit (Tx) LED
The yellow LED ashes when the motor controller transmits the
data to the serial link transmit line. It can be used for the fault
nding the serial link.
