Each SENSYS 240 Connector must be connected to Power and CAN Cabling or aterminate connector.6 SYSTEM OPERATIONThe below defines the system operations:The LCO will continuously verify that the sensor works. This will be done with a Heartbeatmessage which will be transmitted to the sensor each 10 seconds interval.Information of sensor problem will be stored in the log file and on the LCO data screen.The sensor will also perform a calibration, if the internally sensor temperature increases over theaccepted level. The sensor will then report to the LCO about the calibration result. Aftercalibration the sensor will go in standby mode, if the temperature is still high.The sensor will also perform a calibration, if the internally system voltage decreases to a notaccepted level. The sensor will then report to the LCO about the calibration result. Aftercalibration the sensor will go in standby mode, if the internally voltage is still low.The LCO can also perform an ordered sensor calibration. The sensor then performs a calibrationand reports the result to the LCO.7 SENSYS 240 OPERATION7.1 Sensor start-upAfter power on the sensor start with red LED indication.The sensor will then start with start-up tests.The start-up will verify the following:1. The MCU Flash memory and SW checksum.2. The MCU RAM memory.24816573

That the internal serial number HW works.5. That the internal real time clock works.6. That the in voltage is accepted to the sensor.7. That the internal voltage is accepted to the DSP board.8. That the internal voltage is accepted to the MicroWave unit.9. That the internal temperature is accepted.10. That the internal system voltage is accepted.11. That the internal DSP HW works.12. That the internal MCU-DSP FIFO works.If the above start-up test passing, then the sensor application will start and the LED will changecolour to green. Otherwise the application will not start and the LED will still be red.If the above start-up test failed a Reset command from LCO is necessary to perform a new start-up test (not enough with a power off/on sequence).The start-up test will also verify the following warning tests:1. The internal EEPROM checksum.2. That the internal backup voltage is accepted.The result of the warning test will be reported to the LCO via the Heartbeat message.7.2 Continuos Sensor testThe Sensor will continuos verify the following:1. That the internal temperature is accepted.2. That the internal system voltage is accepted.If any of the above tests fails, the sensor will automatically perform a calibration and report theresult to the LCO. After that and if the alarm is still activated the sensor will turn off.If the sensor has turned off and the alarm has been released the sensor will restart againaccording to the Sensor start-up chapter above.8 LCO OPERATIONMake sure that the files LCO.EXE, LCO.DAT and LCO.STP are located in the same directory.Start the application by double-clicking LCO.EXE. A window similar to the one in Figure 1 will

The tree view to the left contains all the devices that the application is responsible for.The two first levels are currently unchangeable, whereas Sites, Sensors, Cameras and TrafficLights are possible to add, configure and delete. One site (Office) containing one sensor (Sensor1) is defined in the delivered set-up files, in accordance with Figure 1.The application does not send anything to any device until a measurement is started by right-clicking on a site and selecting “Start Measurement…”. If that is done, LCO will try to connectto the devices in the site and then start sending heartbeat requests to them every 10 seconds.8.1 CalibrationCalibration requests are sent to every sensor in a measuring site with the periodicity supplied inthe ”Options | Preferences…” dialog. In order to manually request the sensor to perform acalibration the following steps should be performed:1. Select the site in the tree view and click the right mouse button. A pop-up menu appears.2. Select “Start measurement..”, supply user names in the “Start measurement” dialog and press“OK”. A log window appears.3. Select the sensor in the tree view and click the right mouse button. A pop-up menu appears.4. Select Properties… from the pop-up menu. The “Sensor Properties” dialog appears.5. Select the Calibration tab. The dialog should look as in Figure 2.6. Press the Calibrate button.

Figure 3 shows a dialog where this information is included. Figure 38.2 Resetting the sensorIn order to reset the sensor the following steps should be performed:1. Select the sensor in the tree view and click the right mouse button. A pop-up menu appears.2. Select Reset… from the pop-up menu. The “Reset” dialog appears as shown in Figure 4.3. Choose the appropriate type of reset, here always the normal reset and then select OK.Figur 6

The directory where the logfiles are stored is configured in the ”Options | Preferences…” dialog. It is currently set to”C:\LCO_logfiles”. The log file names are constructed as follows:<site code>_<LCO date>_<LCO time>.logwhere LCO date is formatted as YYYYMMDD and LCO time is formatted as HHMMSS. Thefile begins with a chunk of header information and ends with the time when the file wascompleted. In between these blocks message and system logs are stored. The messageinformation is in most cases stored as a hexadecimal dump of the raw binary message data.9 APPENDIXAppendix No. Name[App 1] None9.1 Appendix 1.None.
