2.14 Data Logger The GS820 includes a data logger that records all significant events including actual sensor values and a date and time stamp. The data logger memory can hold over 32 000 records, this is equivalent to several days or several years of operation depending on the recording mode selected and machine use. The data can be extracted using a USB mass storage device (USB key) and then transferred to a personal computer for analysis. 2.
2.15 Sensor List All sensors in the GS820 system are programmed in the sensor list. The GS820 uses information from all sensors in the sensor list. Conversely the GS820 will not use or display information from sensors that are not programmed to the sensor list. If a sensor is removed from the crane then it must be removed from the sensor list. If a sensor is replaced the sensor list must be updated with the new ID number.
