Motor
does not
rotate
The screen shows that the motor
works. In fact, the motor does not
rotate.
Check whether the pump body joint is loose and
reliable.
Check whether the current code in “settings” is too
small. Set the current code consistent with the
product.
The motor connecting wire is loose and return to the
factory for repair.
Power wire is loose and return to factory for repair.
Motor
stalled
The original pump head / tube can
run at a certain speed, but the new
pump head / tube cannot run.
The new pump head / tube should be run for one or
two minutes at a lower speed.
The maximum speed of the motor
suitable for the pump head / tube
is exceeded.
Please refer to the above operation curve to select the
reasonable speed corresponding to the pump head /
tube.
Inaccurat
e flow or
liquid
volume
There is a big difference in the
liquid volume or flow rate after
replacing the tube.
Recalibrate and input accurate calibrated parameters.
You can take the mean value after multiple
calibrations, and then enter the mean value.
The tube has been used for a long
time and its resilience has
decreased
Replace the tube.
Accuracy requirement is not
appropriate.
The flow rate / speed / tube diameter are inversely
proportional to the accuracy. Try to use smaller
diameter tube.
