DescriptionVilter Vision 20/20 Series Micro-ControllersThe Vission 20/20 control panel is a high quality embedded industrial controller for screw compressors. The control panel is a complete factory assembled, wired and tested assembly mounted on the screw compressor unit. The Vission 20/20 is designed to control and protect the compressor unit.
Hardware FeaturesIndustrial embedded CPU control unit Field wiring terminal strip Oil heater relay Emergency Stop button Solid state input and output circuits DC power supply Circuit breakers AC line filter for EMC suppression
Transducers & SensorsVission 20/20 accepts most sensor types, which can be easily set-up in the control panel configuration screen. Standard pressure sensors are high quality refrigeration-rated devices with 4-20 mA output signal. Standard temperature sensors are RTDs. Motor current sensors can be CTs or 4-20 mA transmitters. No refrigerant piping in the control panel.
Display & Data EntryThe Vission 20/20 screen layout is unique in the refrigeration industry in that the most important parameters and controls remain visible regardless of what screen the operator is on. Most importantly, the compressor stop button is always visible and is not hidden when navigating to other screens.
Operating ControlsPressure/Temperature control set-points-(2) Suction pressure controllers-(2) Process temperature controllers Auto-cycle control points VFD control set-points Pump-down control set-points Pull-down control set-points
Historical DataA historical data trending screen is provided to graph selected parameters that are monitored by the Vission 20/20. Short term data is stored in the Vission 20/20 memory and long term data is stored to a USB thumb drive.
