Energy Alternatives - Your Source for Environmentally Friendly Energy

A user-friendly control unit that maintains two-way communication with the pump and monitors the operating conditions. Built-in diagnostics indicate faults and dry-running, display operating status power consumption and level switch input.

Communication between the CU 200 and the pump takes place via the pump power supply cable. This is called mains borne signalling (or Power Line Communication), and this principle means that no extra cables between the CU 200 and the pump are required. It is possible to start, stop and reset the pump by means of the on/off button.

The system monitor display on the CU200 shows the following: • Pump operation • Full Tank • Input Power ( Watts ) • Alarm Indicator for dry running, overvoltage, overload and overtemperature.
