WARNING
REASON
EXPLANATION / SOLUTION
The POWER LED blinks.
The pump to which the frequency
converter is connected is not operative
for automatic running.
Check that there is no manual shutdown
(AUTO/STOP button on the keypad), a
remote stop (auxiliary input active
remote stop) or a general stop of the
network of frequency converters (occurs
when any general critical parameter is
being modified).
The RUN LED blinks.
The frequency converter is in the process
of stopping the pump.
12. WARNING MANAGEMENT
One of the main principles of the frequency converter is to try to avoid the failure of the hydraulic supply. To do
this, the frequency converter has systems that, in the event any reading for the pressure/consumption of the motor
is outside of the established limits, it may partially lose its ability to try to avoid the frequency converter locking
and, therefore, avoid the failure of the hydraulic supply.
A clear example is an excessive consumption of the electric motor. In this specific scenario, the frequency converter
will limit the rotational speed of the motor to avoid its deterioration, maintaining the consumption of the motor
equal to the nominal consumption, thus the hydraulic installation will continue to receive flow from the pump, not
at the working pressure established, but at a somewhat lower pressure.
A table specifying the current state of the system operation, according to visual warnings that are shown using both
the LEDS and the main screen can be found below:
