c-pro mega RACK is the control solution, flexible, modular and programmable, able to cover all application needs of all modern single
circuit compressors pack up to 4-8 compressors. It’s inside the most powerful family of the programmable line and they assure the solution in all high complexity applications in compressors power packs control thanks to their wide availability of I/O, bus communication (with CANbus or Modbus protocol) and high configuration capability.The visualization of these products consist of 4 x 20 alphanumeric LCD display integrated in the controller.The controllers are easy to install inside an electrical panel (on DIN rail). Through the serial port it is possible to connect controllers to the plants monitoring and supervision system RICS or to telemaintenance external networks. Among the several control and regulating
functions one highlights:
• predefined I/O configuration selectable by parameter
• compressors throttling management (up to 3 throttling valves per compressor)
• management of different power compressors
• capability to control compressors and fans by inverter
• condenser pressure regulation by condenser fans management
• refrigerating power throttling for high pressures
• suction line load leak compensation
• floating condensing
• daily programming (RTC).
