This fault can be caused by:
• 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.
This fault can be caused by:
• Mechanical binding from debris in pump.
• Electrical failure of the motor.
• Incorrect setting of Motor Overload Setting switches.
