Control Panel Message Of "Power Off; Control Panel Message Of "Pressure Lo; Control Panel Message Of "Power Failure; Control Panel Message Of "Conductivity Hi - EcoWater CHC Series Service And Troubleshooting Manual

5.7.3 Control Panel Message of "Power OFF"-

No action required, this indicates that the motor controller's HOA power switch is in the OFF
position.

5.7.4 Control Panel Message of "Pressure LO"-

This indication is shown when the pressures of the Filter or CHC have not reached the
appropriate pressures. Verify that the strainer baskets are clean, and that no isolation valves are
closed. Other problems may be associated with a pump failure or clog in suction piping.
Contact EcoWater CHC Service for further assistance.

5.7.5 Control Panel Message of "Power Failure"-

This indication is shown when the motor starter has recognized a loss of a Supply Phase, or the
motor as caused the failure of the thermal overload. Turn off the power to the motor starter by
turning OFF the power disconnect. Open the motor controller and reset the Contactor's Reset
knob. Close the motor starter and try to initiate the pump again. If the pump fails to start,
contact the appropriate personnel to verify the power phases as well as monitor the motor's
amperage. In many cases, problems with the power system due to weather may cause the
thermal overload to fail, if resetting the overload works, please verify the pump motor's
amperage, if it is within range, monitor the function of the system to see if the failure continues.
Contact EcoWater CHC Service for further assistance.

5.7.6 Control Panel Message of "Conductivity HI"-

This indication is shown when the conductivity value is exceeding the upper alarm limits as set
in the Set Up screens. This is normally an indication that the blow down or its piping is
plugged or non functional. It can also be an indication that the make up water source has lost is
supply pressure and make up is not being added to the system fast enough to keep up with the
blow down rate. If the water supply system has failed, take appropriate actions with regard to
the supply, and you may need to turn the Filter skid's power OFF while the tower's water level
increases.
