Task Frequency Check error messages − Clean surface state sensor window As needed Clean surface temperature sensor Annually Replace air temperature and humidity sensor filter Annually Cleaning Surface State Sensor Window • Cloth • Glass cleaner 1 2 3 1 Surface state sensor 2 Window 3 Hood Clean the window daily before use. For cleaning, the mobile sensor can remain mounted on the vehicle. Check the surface state sensor before use and after car wash, and clean if necessary. Check the surface state sensor more often if the conditions require it. When cleaning, remove possible dirt, ice, and snow.

2. Apply glass cleaner on the window of the surface state sensor. Clean with a soft, lint-free cloth. 3. Clean the hood. 4. Attach the hood to the body by turning the hood clockwise. Make sure that the markings in the hood and sensor body are aligned. Cleaning Surface Temperature Sensor • Cotton swab • Compressed air or air pump • Glass cleaner 1 1 Surface temperature sensor Clean the surface temperature sensor annually, or more often if conditions require it. 1. Remove the surface temperature sensor from the body. Reference Guide M212309EN-A 2

turn it clockwise. Remove the cotton swab by turning it counterclockwise in the thread. If required, use compressed air or an air pump. 3. Attach the surface temperature sensor to the body. Replacing Air Temperature and Humidity Sensor Filter • Screwdriver Torx 10 1 2 3 1 Air temperature and humidity sensor 2 Probe body 3 Filter Replace the filter when it is damaged or dirty. The replacement filter comes with an O ring, but do not use it. 1. Carefully remove the filter from the probe. Holding the filter by its collar, rotate the filter counter- clockwise, then pull it out. Do not touch the sensor heads. CAUTION! 2. Without delay, install the new filter carefully on the air temperature and humidity sensor. Rotate the filter clockwise, making sure the filter sits straight and meets the threads properly.

LED Status Orange Powered up Green (steady) Start-up ongoing Green (blinking) Operational Red System is in error state and cannot be used Table 3 Troubleshooting Problem Probable Cause Actions Installation and Setup Phone is not showing data. Device pairing was not successful or the system is not getting power. Check that the car charge adapter and car phone charger are connected and the mobile sensor and mobile phone are powered. If the Bluetooth module LED is still red, redo the pairing. Installation was verified and mobile sensor adapted to road surface types, but mobile sensor still gives inaccurate readings. Road was not completely dry when road type adaptation was performed. Carry out the road type adaptation again. See Vaisala Mobile Detector MD30 Setup Guide. Road surface type in the area of operation differs significantly from the road surface type in the location where adaptation was performed. Plate was not clean and dry during plate calibration. Carry out the plate adjustment. See Vaisala Mobile Detector MD30 Setup Guide. Plate was not positioned correctly during plate calibration. Calibration gets stuck or does not succeed. There is an active error. Check Unit status and Error status information in RoadAI, and act on any open errors. Dry road not available. − Give the values manually or use the factory settings until you can do road type adaptation on dry road. Operation System is in error state (mobile sensor LED is red). Several possible causes. Restart the mobile sensor. If the error persists, see the following table for more troubleshooting information. Phone is not showing data. System is not getting power. Check that car charge adapter and car phone charger are connected and mobile sensor and mobile phone are powered. Reference Guide M212309EN-A 4

Data has been uploaded to the server. − Check the error message for information about the error and follow the relevant instructions. Table 4 Error Messages Bit 1) Message Probable Cause Actions 0 Surface temperature sensor error Cables may be loose, damaged, or disconnected. Check the cables and connectors. If the problem persists, replace the mobile sensor. 1 Air temperature error 2 Relative humidity error 3 Reserved for future use - - 4 Laser status error - Restart the mobile sensor. 5 Laser heating error 6 Excessive ambient light detected Sunlight is reflected from road surface to mobile sensor. Move the vehicle or reposition mobile sensor. 7 Receiver error − Restart the mobile sensor. 8 Signal level out of range, gain adjustment limit reached − Check the installation height and angle of the mobile sensor. 9 Received signals contain too much noise − Check that the mobile sensor is firmly attached to the vehicle. 10 Optical measurement data timeout − Restart the mobile sensor. 11 Low input voltage Incorrect operating voltage. Check the operating voltage. 12 High input voltage 13 Flash failure status - Restart the mobile sensor. 14 Internal temperature too high Mobile sensor overheated. Disconnect the mobile sensor from power supply. 15 Reference status: 0 = OK 1 = Invalid or not set − Verify the installation with the reference plate and adapt the mobile sensor to road surface types. 16 Factory calibration status: 0 = OK 1 = Not calibrated − Return the mobile sensor to Vaisala. 17-31 Reserved for future use − − 1) Bit is shown in MD30 interface response data message, not in RoadAI.

Bit 1) Message Value Description 0 Not ready to measure 0 = Ready 1 = Not ready Bit 0 is set only when unit is started up. The flag is cleared when the unit has reached fully operational status for the first time. Measurement data may be invalid. If the condition persists, check error bits. 1 Reference setting ongoing 0 = Not ongoing 1 = Ongoing If reference setting does not start, check status information bits 10 ... 13 and error bits. 2 Laser temperature change in progress 0 = Not ongoing 1 = Ongoing Unit operational, but measurement data may be invalid. Wait for the laser temperature change to finish. If the condition persists, check error bits. 3 Reserved for future use - - 4 Window heating 0 = OK 1 = Not working If heating is not working, monitor window contamination. 5 Low input voltage detected 0 = Voltage OK 1 = Voltage low Unit operational, but check the input voltage. 6 High input voltage detected 0 = Voltage OK 1 = Voltage high 7 High internal temperature detected 0 = Temperature OK 1 = Temperature high First notification of unit getting too hot. 8 Temperature unit 0 = °C 1 = °F − 9 Layer thickness unit 0 = mm 1 = inch − 10 Reference setting interrupted due to laser temperature change 0 = False 1 = True Repeat the reference setting when laser temperature change has finished. 11 Reference setting interrupted due to hardware error, check parameter 0x56 0 = False 1 = True Check error bits and parameter 0x56, which contains the reason for the error. 12 Reference setting values are not updated due to poor signal quality 0 = False 1 = True Excessive variation in road surface type.
