Rotary encoders with web-based diagnostic system
Leine and Linde’s XHI 801 and XHI803 rotary encoders are equipped with a web-based Advanced Diagnostic System (ADS) providing real-time tracking of the generator condition as well as position and velocity for the rotor. When equipped with ADS, these encoders are also able to continuously monitor vibration, temperature and encoder status information. This can be used to assess the overall health of the generator and encoder together. This allows for scheduled generator maintenance at convenient times rather than as a result of inopportune breakdowns.
ADS Online provides a connection from the encoder’s diagnostic system directly to a PC or to an Ethernet network. With the assistance of PC software, maintenance technicians can obtain detailed analyses directly from the encoder during service operations in the nacelle. When connected to a network, secure access to generator and encoder data is available directly within the control room. System managers can set custom warnings to ensure vibration doesn’t exceed damaging levels, program levels for frequency, and shaft speeds to indicate overspeed or standstills. It also can ensure that the machine does not overheat, detect voltage drops in the power supply, or choose to receive an automatic warning when the encoder reaches a certain number of operating hours.
