Fire alarm system, part of preventive program of “ENERGIA” insurance company. The system is built oh the basis of APOLLO fire alarm transducers and PIS24 fire alarm central unit. It performs automatic alarm signaling and logging in case of fire appearance danger.
Automation system for BROU (fast acting reduction and cooling device) monitoring and protection. The system is built on the basis of programmable controllers SIMATIC S7-214, production of SIEMENS AG – Germany. It automatically monitors the state and operates the action of BROU, preventing the appearance of damages. Information is reported and visualized on the monitor of the operator station of Boiler 7.
Diverter gate monitoring and control system. The system is built on the basis of programmable controller SIMATIC S5-100U, operator panel OP5, production of SIEMENS AG – Germany, SENACO Plus sensors, production of MILLTRONICS – UK and IBM PC/AT operator station. The system performs uninterrupted monitoring and control of the work of the Diverter gates. Any blocking of a gate causes alarm message appearance. The monitored parameters, processes, working messages, alarm messages are visualized on the monitor of the operator station. The operator station manages the whole system, processes, archives, stores and prints by key the information for the work of the system. A local visualization of some of the parameters on OP5 is foreseen.
Three ultrasonic level monitoring systems. The systems consist of 30 pcs ST25CT, ST50UV, XPS10 and XPS15 ultrasonic transducers, BICII communication module and 3 pcs. AiRanger XPL Plus programmable ultrasonic station with relay output modules SAM-20, production of MILLTRONICS – UK. They perform uninterrupted monitoring of the level in 30 vessels. At reaching of a fixed pre-set level values the systems automatically switch on/off pumps and operate the filling/empting of the vessels.
Ice cream mixture level, volume and temperature monitoring system. The system is built on the basis of programmable controller SIMATIC S5-102U, production of SIEMENS AG – Germany, 20 pcs. ST25CV ultrasonic transducers, 2 pcs. AiRanger XPL Plus ultrasonic stations, production of MILLTRONICS – UK, 20 pcs. Pt100 sensors and 2 pcs. IBM PC/AT operator stations. It performs uninterrupted monitoring and control of the temperature, the level and the volume of ice cream mixtures in 20 vessels by keeping of the optimum conditions for the preparing of the mixtures. The information for the work of the system is visualized, managed archived and stored by the two operator stations.
