• High input voltage.
This fault will be displayed if the phase to phase input voltage is
greater than 275V for 230V units and 560V for 460V units.
9 Blinks Motor Overload This fault can be caused by:
• Mechanical binding from debris in pump.
• Electrical failure of the motor.
• Incorrect setting of Motor Overload Setting switches.
