NOTE: The blink code is displayed using the power
indicator on the motor. The blink code given below
indicates the sequence. For example, blink code 2–6
indicates 2 blinks, then 6 blinks. The sequence then
repeats.

Description
Description
1
Flow exceeds maximum target; also indicates pump runaway condition exists.
2
Brown out; voltage supplied to motor is too low.
3
Over voltage; the motor supply voltage is too high. For DuraFlo and Xtreme lowers, cavitation at
changeover can cause this alarm by turning the motor into a generator. For all lowers, if the inlet is
pressurized enough, the motor can be pushed to generate enough voltage to cause this alarm.
4
An internal control board hardware failure is detected.
5
Over temperature.
6
The Mode Select knob is set between Pressure
and Flow
. Set the knob to the correct
mode.
7
Low supply voltage detected at startup.
2–6
AC power is lost.
3–5
Internal thermistor disconnected.
3–4
Software versions do not match.
3–6
Circuit board communication failure.
4–5
Internal software error.
5–6
A calibration of the automatic encoder and stroke range is in process. (This process is initiated
from the DIP switch that is internal to the motor.)
