AcornVac Zone Control is a fully networked electronic valve control system that allows complete visibility and control of individually addressed vacuum waste extraction valves and ancillary or special purpose valves used for water supply shut off, flush, rinse or temperature control. Control and communication with individual valves is facilitated through system ZCP, which provide 24VDC power and control function for valves servicing up to 12 individual vacuum lifts. The entire system is designed to accommodate a maximum of 23 Zone Control Panels, or 276 individually addressed vacuum valves and 92 ancillary valves. The Zone Control System includes local area network communication with all valves which allows them to be remotely monitored and controlled in real time, either from the vacuum center, or remote locations and building monitoring systems or networks. The system includes “fail-safe” logic, which is designed to monitor ongoing vacuum valve activity and automatically implement corrective measures in the event of irregular valve operation to ensure continuous waste drainage.
Individual electronic controller does not require dedicated power source or battery; power for valve control is provided by the Zone Control Panel (ZCP).
Valve open time is optimized to ensure maximum operational efficiency of the entire system or manual over-ride to a fixed duration
Data recording is provided which captures all valve activity for future review and programmed operation adjustment
Fail-safe logic, designed to monitor ongoing lift activity and automatically implement corrective measures in the event of irregular valve operation
Each ZCP monitors a fixture for a signal which is created automatically, or by pressing a button. When that signal is received, the ZCP opens a normally closed extraction valve to remove the waste from the fixture and transport it to the vac center. The duration the extraction valve is open is precisely controlled and optimized to minimize operation of the vacuum pumps. Each ZCP also provides control activation for up to four programmable ancillary valves associated with the waste extraction valve and used to facilitate waste drainage. Examples include flush valves, rinse valves, temperature control and shut off valves.
