- 14. Machine protection and monitoring system TNC2000 Modules •Phase marker Used to provide phase marker signal to the monitor modules and data acquisition unit in TNC2000 system. It provides also a rotating speed measurement. Outputs: • Two buffered phase marker signal TTL(0-5V) • 4(0)-20mA DC proportional to rotating speed • 0-10V DC proportional to rotating speed • one binary of alert/alarm status • -24 V DC as supply for proximity transducer •Power supply The MPS Power Supply delivers reliable, regulated power for all monitors and their associated transducers. When two power supplies are used the system supply is redundant. Both supplies are powered simultaneously. Either supply can power a full rack. Removing or inserting a power supply module will not disturb operation of the rack.

- 18. Application 2. 15MW Hydrogenerators In this application, the SMMhydro system version is installed on four hydrogenerators, having speed of 214 rpm (rotation cycle time 3.75 Hz). The following set of measurements is performed for each machine: - 2 channels for absolute axial vibrations - 2 channels for absolute radial vibrations - 8 channels for relative vibrations of four bearings in two axes - 3 channels for axial movement - rotating speed measurement - phase marker For data acquisition, the JAD16/16For data acquisition, the JAD16/16 Data Acquisition Units are installed. Data access is limited to only one user and the data is used mainly for diagnostic purposes. Additionally, signals received from TNC2000 are fed to a protection system and to operator’s terminal for visualisation. To keep investment costs down, the communication between data acquisition unit with diagnostic terminal and protection and visualisation systems is via common optical network.
