Content	6/20 Housing / Environment Case:Aluminium box, 30 x 55.5 x 15mm (see Fig. 3) Weight:55 g Protection index:IP67 TemperatureOperating: -20° to 70 °C Storage: -40° to 100 °C Humidity:0 to 100 % Figure 3: Dimensions of the SeTAC aluminium case SeTAC INSTALLATION Due to the variety of the functions that can be performed by the SeTAC, mounting information cannot be specific for all the equipment and applications. Therefore, the guidelines detailed in the following paragraphs are only the general instructions that should be considered for mounting and the electrical connection of the sensor. Installation and service of the SeTAC must be performed either by people who s trained and by Sequoia IT personnel and according to Sequoia IT guidelines and suggestion, or directly by Sequoia personnel. Positioning The SeTAC should be mounted in a place where the phenomena to detect can be mechanically transmitted to its box. The closer the sensor is mounted to the source, the more satisfactory will be the monitoring results. Care must be taken in mounting the sensor and attention is required in order to prevent damages to the sensor, to the cable and to the machinery to which the SeTAC is applied. The SeTAC box must be secured to the equipment that has to be monitored by drilling and screwing (there are 4 holes for mounting), especially if the disturbances to detect are high in frequency. In order to get the best signal measurement and analysis, the SeTAC should be mounted on a flat surface, prepared using the sensor dimensions as guidelines. Moreover, care must be taken to the fixing devices. These must be securely fastened so that they do not add other vibrations to the monitoring system and do not modify the signal that is measured by the SeTAC. The sensor must be mounted on the most relevant part of the equipment, i.e. the point in which the measured vibration is effectively representative of the overall stress to which the equipment is subject. For example, when the monitored equipment is a metal cutting machine, the recommended location for fixing the sensor is the machine spindle nose. It is necessary to be cautious not only to the way in which the SeTAC is fixed to the equipment, but also to the cable mounting. Secure the cable with appropriate mechanical fasteners, being careful not to break the insulation or crush the internal wiring. Provide adequate slack in the cable to allow it to flex when moving machine elements are present. Programming The SeTAC belongs to the category of the smart sensors. It is a programmable device and can perform different functions according to the uploaded software. By using a personal computer – connected to the SeTAC via RS232 or through the USB port – and the SeTAC Interface board that is provided together with the SeTAC, it is possible to modify the current monitoring parameters. Moreover, a new software can be uploaded into the device at any time. In daily use, the SeTAC is only connected with power supply and a PC only serves as a graphical user interface for displaying waveform signals.
