A Brief Description
The VPR 19140-Compound Control System controls a complete refrigeration plant, which can consist of 2 compressor compound resp. chiller systems, the necessary condenser systems and up to 64 Cold Storage Controllers. Each of the cold storages is equipped with an own Cold Storage Controller unit which works independent and interchanges information via databus. The VPR-System outclasses conventional systems based on discrete components:
• Less local requirement, less wiring
• Dramatically increased functionality, e.g.
  - Prioritized forwarding of each single error message
  - Each error message with plain text
  - Integrated Data Logging System for Actual Values and
   Setpoints
  - Direct modem connection, Remote Maintenance possible

• All information appears on the VPR-Screen:
  - Parameters and values of the whole refrigeration plant
  - Service informations like Terminal Plans and I/O-States

• Adding new functions by software-update
• Expanding of Inputs / Outputs by hardware modules

• More cost-effective for large refrigeration plants

• VPR 19140 controls 2 complete compressor compounds including condenser fans or max. 2 chiller systems with different refrigerant circuits
• Controls up to 64 networked cold storage controllers (CSC "s).
• A backlighted LCD-screen shows the parameters of all plant components, including these of the cold storage controllers.
• Integrated Data Logger System for recording Actual Values and Setpoints of the Cold Storages
• User management, multiple acces rights
• Suction pressure control / base load control for each compound
• Various optimization methods, e.g. via enthalpy or low power optimization.
• Condenser pressure (fan) control / base load control for each compound, max. 12 stages each
• Speed-controlled compressors and fans can be handled
• Without additional installation of mechanical switches all connected components can be switched on/off manually.
• Superior cold storage controller management. All values, parameters and states of linked units can be read from the screen, can be remote controlled and processed for optimizing methods.
• Solenoid valves will be controlled foreseeing
• All sensor- / transmitter inputs are monitored, in case of failure the unit continues operation in an emergency mode
• Plant messages like compressor alarm, state messages or similar are captured and handled, compressor / fan motor runtimes are recorded.
• Messages can be distributed to different priority levels and can be forwarded by relay, interface or modem.
• A wide message memory allows to fetch the last messages with clear text, time and date.
• Interfaces for connecting E-Link network, PC and modem.
• VPR has an integrated message report system which forwards alarm messages to a host automatically. The plant can now be observed, and remote controlled by the host.
• Configurable by customer
• Integrated 6-channel annual time-switch
• Remote maintenances (e.g. program update) via interface
• Optimized hardware usage, no unused inputs/outputs
• Improved failure diagnosis by the help of function-LED "s at the rear side
