Need help?Do you have a question about the WURM DCC-XP V6 and is the answer not in the manual?
The DCC-XP V6 is a rack control unit with integrated condensation pressure control, designed for refrigeration plants. It is a versatile device that can manage various compressor types and configurations, offering extensive control and monitoring capabilities.
The DCC-XP V6 serves as a central control unit for refrigeration racks, specifically designed to manage compressor output and condensation pressure. It supports a range of compressor configurations, including 1-, 2-, or 3-step compressors, with or without cylinder lift, and equally or unequally graduated compressors. It can also manage compressors with a constant compressor via a Compressor Frequency Unit (CFU). The device is extendable by an additional DCC-XP unit to support up to 8 capacity steps.
A key feature is its integrated condensation pressure control, which can be managed by a speed regulator or an ADC multiple contact switch. This allows for precise control of the condensation pressure, contributing to energy efficiency and stable plant operation. The device also supports outside temperature-guided condensation setpoint control using a TRK277/7 PLUS temperature sensor.
The DCC-XP V6 monitors and controls various operational parameters, including compressor downtime, rack downtime, and base load changes based on run time and switching frequency. It includes an operating hours counter for each compressor step, enabling effective maintenance planning.
For enhanced plant stability and safety, the device incorporates features like peak load shedding and fast return, which help manage sudden changes in load. It can also control compressor output through a voltage input and allows for suction pressure increase via a switch contact. Cyclical forced start-up for condenser fans and peak load limiting are also supported.
The device provides a clear display of the current operating status of the refrigeration plant, making it easy for service technicians to monitor performance. It integrates seamlessly into the Wurm system via the Wurm CAN communication bus (C-BUS) and FRIGODATA XP, allowing for comprehensive plant management and data logging.
Power Supply: 230V~, +10% / -15%, 5VA approx. Pressure Sensor:
The DCC-XP V6 is designed for ease of installation and operation. It is suitable for top-hat rail installation and can be positioned next to other devices without gaps, making it ideal for integration into fuse boxes or control cabinets. The device features a user-friendly menu for configuring various parameters, including compressor settings, condenser control, P-band, start-up voltage, refrigerant type, and address.
The display provides real-time information on active values for both suction (To) and condensation (Tc) temperatures, as well as their respective setpoints. It also shows the current operating mode and allows for easy navigation through the menu.
For data communication, the device offers a direct connection of a CAN-USB to the service socket, simplifying diagnostics and configuration. The robust CAN bus interface ensures reliable communication within the Wurm system.
The device's ability to manage different compressor types and configurations, along with its extendability, makes it highly adaptable to various refrigeration plant requirements. The inclusion of features like base load change based on run time and switching frequency, and peak load shedding, allows for optimized plant performance and energy management.
The DCC-XP V6 incorporates several features to aid in maintenance and troubleshooting. It includes compressor downtime monitoring and rack downtime monitoring, which can help identify potential issues early. The operating hours counter for each compressor step provides valuable data for scheduling preventive maintenance and assessing component lifespan.
The device's self-monitoring capabilities, including monitoring of connected sensors, data memory, and the microcomputer, ensure reliable operation and alert technicians to any internal faults. The clear display of the current operating status allows for quick assessment of the plant's health.
For diagnostics and service, the direct CAN-USB connection to the service socket simplifies data retrieval and parameter adjustments. The device's robust design and adherence to CE and EAC conformity standards ensure durability and safety.
In case of a fault, the device should be taken out of operation and sent for repair with an exact description of the issue. It is crucial to follow safety guidelines, such as switching off power to the entire plant before any installation, wiring, or removal work, and ensuring that only qualified electricians perform wiring tasks. The documentation also provides a Wurm Infocenter and paperless info resources for additional support and information.
