What to do if my DGFLOW Controller pump is not feeded?
If the pump is not being feeded, the issue might be: * Interruption of power supply: Replace the power supply. * Burned fuses: Substitute the fuses. * Intervention of the line protections: Check the correct protections setting.
Why is my DGFLOW Controller pump always running even when not required?
If the pump runs continuously, even when not needed, it could be due to: * System leaks: Identify and repair leaks greater than 2 l/min. * Flow sensor fault: Inspect and check the flow sensor.
What to do if the current circuit breaker has tripped to protect the DGFLOW Controller power line?
If the current circuit breaker has tripped, it might be because the residual current circuit breaker is inadequate for inverter supply. Replace the residual current circuit breaker with a model suitable for the pulsating components and in direct current (class A).
How to fix INPUT ERROR on my DGFLOW Controller?
If you see an 'INPUT ERROR' (only mod. T/T), the connections LINE and MOTOR might be reversed. Check the connections LINE and MOTOR and connect correctly.
Why does my DGFLOW Controller pump stop too soon when requested?
If the pump stops too soon, it could be due to: * Flow rate sensor fault: Check the flow rate sensor. * Air inside suction manifold: Bleed the suction system. * Pump blocked or damaged: Inspect the pump and eliminate the problem.
Why does my DGFLOW Controller pump stop and fail to restart?
The pump may stop and fail to restart due to several reasons: * Overcurrent absorption: Check the correct current setting, power voltage under load at pump terminals (min -15%), ensure the motor pump is turning freely, verify the rotation direction and wiring size. * Serious overcurrent absorption: Ensure the motor pump isn't blocked, and reduce motor acceleration using the ACCELERATION parameter. * Suction issues: Check suction conditions, prime the pump, inspect suction piping, and verify the motor's rotation direction. * Low pressure: Check for broken pipes. * Voltage deviation: If the supply voltage deviates more than -15% of the plate voltage, check the supply voltage, the section and length of the inverter power cables. If the supply voltage deviates more than +15% of the ...
