Technical description

The status information is used to indicate the current status of the mobile sensor and to issue warnings. The status information is reported in the GET UNIT STATUS, SEND DATA, and SET REFERENCES messages.

Table 1. Status information
Bit 1 Message Value Description
0

Not ready to measure

0 = Ready

1 = Not ready

Unit is starting up. When unit reaches full operational status, the flag is cleared. 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 laser temperature change to finish.

If the condition persists, check error bits.

3 Window contamination warning 2

0 = OK

1 = Contaminated

Window is getting contaminated. Clean the window.
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 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 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 reason for error.
12 Reference setting values are not updated due to poor signal quality

0 = False

1 = True

Excessive variation in road surface type. Find more representative road surface.
13 Reference setting was interrupted by client

0 = False

1 = True

14 Signal levels low, uncertainty in surface layer thickness results

0 = False

1 = True

Unit operational, but measurement data may be invalid.

Verify installation and clean window.

15 Road surface type significantly different from road surface type used in reference setting

0 = False

1 = True

Unit is operational, but measurement data can be invalid. If condition persists, perform reference setting.
16 Layer thickness result produced undefined result

0 = False

1 = True

Verify installation. If condition persists, perform reference setting.
17 Measurement over range, layer thickness measurement range exceeded

0 = False

1 = True

Maximum reported layer thickness 60 mm (2.36 in) exceeded. If this does not represent actual conditions, perform reference setting.
18–31 Reserved for future use -

Reference setting cannot be started if status info bit 0, 1, or 2 is set.

Laser temperature change stops the ongoing reference setting.

1 Bit is shown in MD30 interface response data message, not in RoadAI.
2 Reported by MD30 models that have the window contamination feature.
