Cause
No pump connected or connection to
pump is faulty
Communication error between controller
and pump
Excess temperature
Overcurrent
Pump blocked
Pump has run dry
Overvoltage
Undervoltage
Remedy
• Check that cable is connected correctly
to pump
• Connect the pump to the controller
• Check that cable is connected correctly
to pump.
• Connect the pump to the controller
• Check that impeller unit moves freely
− If the impeller unit is sluggish, the
pump is requiring too much power
• The ambient temperature is too high
Check that impeller unit moves freely
• If the impeller unit is sluggish, the
pump is requiring too much power
Check pump and remove obstacle
• Submerge pump in water
• For dry installation ensure adequate
water supply
Connect the pump to the correct mains
voltage
• The unit is not suitable for use with the
existing mains voltage range
• Keep extension cable to the pump as
short as possible.
− The voltage to the pump is too low
due to the voltage drop in long ca-
bles.
• Use extension cable to the pump with
greater conductor cross-section
− The voltage to the pump is too low
due to the voltage drop in cables with
too small of a conductor cross-sec-
tion.
