Operation
•
Speed up/down:
Change the running speed of
the pump, to adjust the flow. The pump has
9 speed modes, corresponding displayed as
“01-09” in the LED display. “09” Is the maximum
speed of the pump.
•
Feeding ON/OFF:
Press this button to stop the
pump for 10 minutes. After 10 minutes, the pump
will operate automatically. This function gives you
the time to feed your fish without getting food in
the filter. If you press the button again the pump
will work again. If you want to stop the pump
during this period of 10 minutes you need to
unplug it.
Troubleshooting
•
Under voltage protection / overvoltage protection:
When the pump input voltage
is below or above the standard voltage of 10% and holds for more than 1 second, the system
will automatically enable protection to stop the pump. After the input voltage has returned to
normal and holds for more than 3 seconds, the system will automatically restore the pump.
When the under voltage protection is activated, the LED display shows “EL”, when the over
voltage protection is activated, the LED display shows “EH”
• Overload protection:
When the pump is running and the pump load exceeds the rating by
10%-30%, the system identified it as pump overload. The overload protection function is
activated after about 1.5 seconds after the pump stop running. This protection function has the
Inverse-time characteristic, the higher the overload, the faster the trigger. Starts automatically
after the pump stops for 1 second, and the system will repeat the protection process until the
overload is eliminated. When the overload protection is triggered, the LED display the “EF”.
• Over-temperature protection:
The pump automatically stops running when the
controller temperature exceeds 80°C, the LED display shows “EC”. The pump automatically
starts running again when the controller temperature returns to 65°C or less.
