What to do if the DGFLOW Control Panel shows OVER VOLTAGE?
If the DGFLOW Control Panel displays 'OVER VOLTAGE', it means the inverter power voltage is too high (over +15%). You should check the supply voltage.
What causes UNDER VOLTAGE on a DGFLOW Control Panel?
If the DGFLOW Control Panel displays 'UNDER VOLTAGE', it indicates that the inverter power voltage is too low (under -15%). To resolve this, check the supply voltage and the section and length of the inverter power cables.
How to fix OVER TEMP MOD error on DGFLOW Control Panel?
If the DGFLOW Control Panel displays 'OVER TEMP MOD', the inverter module is overheating. Ensure the air cooling channels are free, the fans are working, the ambient temperature is below 45°C, and the maximum operating current is within limits.
What does OVER TEMP CAP mean on my DGFLOW Control Panel?
If the DGFLOW Control Panel displays 'OVER TEMP CAP', the inverter capacitors are overheating. Ensure the air cooling channels are free and that the fans are working. Also, check that the ambient temperature is not above 45°C and verify the maximum operating current.
What causes OVER TEMP BOX error on DGFLOW Control Panel?
If the DGFLOW Control Panel displays 'OVER TEMP BOX', it means the inverter is overheating internally. You should ensure the air cooling channels are free, the fans are working correctly, and the ambient temperature is not exceeding 45°C. Also, check the maximum operating current.
What does LOW PRESS mean on my DGFLOW Control Panel?
If the DGFLOW Control Panel indicates 'LOW PRESS', and you're using a flow sensor, it means either the working pressure is near zero or the pump can't reach the set pressure. Check the pipes for leaks, verify the pressure sensor's operation, ensure the maximum pump pressure exceeds the set pressure, and inspect the pump for wear or obstructions.
What to do if the FIXED SPEED pump fails to start on my DGFLOW Control Panel?
If the FIXED SPEED pump fails to start, it could be due to the ammeter cutout tripping because the pump is drawing too much current. Check the current absorption at maximum load, verify the ammeter setting, and check the voltage at the pump terminals under load.
What does EXT OFF mean on my DGFLOW Control Panel?
If the DGFLOW Control Panel shows 'EXT OFF', it means the inverter is out of service due to an external signal. You should check the external signal to resolve this issue.
Why does my DGFLOW Control Panel pump run constantly?
If the DGFLOW Control Panel's pump runs constantly when not needed, it could be due to system leaks, a faulty pressure sensor, a low 'switch off frequency' setting, or a flow rate sensor issue. Find and fix any leaks, inspect the pressure sensor, increase the switch off frequency setting, and inspect the flow sensor.
Why does the DGFLOW Control Panel's pump stop too soon?
If the pump stops too soon when requested, it could be due to a high switch off frequency setting or a fault with the flow rate sensor. Try setting a lower switch off frequency and inspecting the flow sensor.
