【正文】 deal openly with any other munications equipment, munications controller, or PLC S7300 type can be defined by the user39。 b) duplex host the status of a separate icemaking mode。 d) the icemelting separate cooling mode。 chilled water pumps start and stop, status and fault alarm glycol pump start and stop, status and fault alarm cooling Pump Commitment, status and fault alarmthe pressure of the bypass with significant pressure measurement Showthe cooling tower fan Commitment, status and fault alarm。 the entire control system can be in the load (including the biggest daily total load and fullload) and equipment uptime tables and charts to record for users. All monitoring points and the calculation of the data can be automatically print regularly. Manual / automatic conversion feature Control system configuration flexibility of manual / automatic conversion features. Optimized control According to outdoor temperature, weather, the weather trend, history and other data automatically host the icemelting or priority. Meet the load in the end, under the premise of daily End of cold storage, to run as little as possible hosts. Give full play to advantages of ice cold storage system, saving operating costs. Features automatic operation From the host puter system can work, according to a timetable for the 6 automatic icemaking and control system operation, the status of conversion, the system for automatic fault diagnosis, and remote alarm. Touchscreen display system running, processes, the parameters of nodes, running records, police records. Holidays set features According to the timetable system can be run automatically, but also can be preset holidays, ice control certificates and certificates of ice time, the system does not need the holiday season, when the supply of places to stop airconditioning cooling. . 8 Under the crew operating functions The crew operating functions are as follows: a) manmachine dialogue. The operator through the touch panel can be interactive, user interface pletely in the culture, with tips, help, and the set of parameters, key settings, fault enquiries, history, and other functions. b) System settings. Including the operation of password settings, running set up, run the timetable set records overflow with automatic / manual / test selection, holiday settings, the system set of parameters (including the node temperature, pressure, the flow of the medium, the reservoir of ice, icemaking Rate, the icemelting rate, the valve open, end load, and so on.) .c) Record of failure, running records, historical records. Remote Control Control system through telephone lines or broadband, connections with the expert system, the system operational control, parameter changes, such as data collection, the system continuously improved and upgraded version of the software, allows users to get better service. Remote Control is aimed at users through the PSTN (public switched work transmission) of frozen remote monitoring station at different places. At the same time can achieve longrange adjustment, remote monitoring and timely maintenance, and other online, thus greatly reduce the intensity 7 of the work, reducing costs of the project. Systems
