The NAV350 must only be installed, commissioned and serviced by adequately qualified personnel. Repairs to the NAV350 are only allowed to be undertaken by trained and authorised service personnel from SICK AG. The following qualifications are necessary for the various tasks:...
The NAV350 is a sensor for use indoors. Important In case of any other usage as well as in case of modifications to the NAV350, e.g. due to opening the housing during mounting and electrical installation, or to the SICK software, any claims against SICK AG under the warranty will be rendered void.
The operating instructions must be made available to the operator of the system where the NAV350 is used. The operator of the system is to be instructed in the use of the de- vice by specialist personnel and must be instructed to read the operating instructions.
Pay attention to the laser safety regulations as per IEC 60825-1 (valid version). Important No maintenance is necessary to ensure compliance with laser class 1.

Operating Instructions NAV350 Laser positioning sensor Environmental protection The NAV350 has been designed to minimise environmental impact. It uses only a minimum of power. While working, always act in an environmentally responsible manner. For this reason please note the following information on disposal.
Chapter 3 NAV350 Product description This chapter provides information on the special features and properties of the NAV350. It describes the construction and the operating principle of the device, in particular the different operating modes. Please read this chapter before mounting, installing and commissioning the device.
The LEDs signal the operational status of the NAV350. The NAV350 has four LEDs. These visually signal the actual operational status and the sta-- tus of the continuous self-check. The LEDs are on the front of the device on the NAV350. tab. 4 shows the function of the LEDs.
Operating principle of the NAV350 The NAV350 has an opto-electronic laser measurement system that electro-sensitively scans the contour of its surroundings in a plane with the aid of laser beams. The NAV350 measures its surroundings in two-dimensional polar coordinates. If a measurement beam is incident on an object, the position is determined in the form of distance, direction and remission.
The incident radiation is not reflected diffusely in all directions by reflectors, but direction-- ally. As a result a large portion of the energy emitted can be received by the NAV350. The NAV350 makes use of this situation to be able to exactly measure the positions of reflec-- tors.
3.5.3 Scanning range of the NAV350 The scanning range of the NAV350 is dependent on the remission of the objects to be de-- tected. The better a surface reflects the incident radiation, the greater the scanning range of the NAV350.
Operating Instructions Chapter 3 NAV350 Important In particular on the usage of the NAV350 for the output of measured values, it is necessary for a reliable measurement that the beam is incident on the object several times. Landmark detection In the...
40). These reflector are either measured and their coordinates saved in the NAV350 or they are taught-in by the NAV350 (mapping). The NAV350 passes the position data to the AGV’s vehicle computer on request. The vehicle computer steers the AGV along the programmed and therefore pre-defined route and cor- rects any course deviations that occur with the aid of the NAV350.
The vehicle is not moving. • There are at least three reflectors in the field of view of the NAV350. Depending on the number of measured reflectors and number of reflectors in the current layer, initial positioning can take several seconds.
The radius of the detection window can also be configured as a function of the distance be- tween the NAV350 and the reflector. For this purpose the start and end point of a linear function and the size of the detection window at the start and end point are transferred to the NAV350.
NAV350. The influence of the position data from the NAV350 on the correction is application-specific and depends on the quality of the odometry and the positioning tolerances allowed in the system.

However, the setting cannot be saved. Important The reflector layout is to be designed such that for the NAV350 at least three reflectors are always visible in the sectors that are not muted. If this is not the case, the NAV350 determines the position using all visible reflectors (similar to the measuring accuracy, see section 3.7.2 “Measuring accuracy”...
The situation of an overlapping reflector occurs if the angle between two reflectors from the point of view of the NAV350 is less than 0.6°. The reflector placement is to be selected for this case such there are at least 3 further reflectors in the field of view of the NAV350.
Subsequent movement of reflectors Movement of reflectors that are also still in the measurement area of the NAV350 after they have been moved, will make the result of the measurement incorrect and must be correct-...
In addition knowledge of the data exchange between a laser positioning sensor such as the NAV350 and the vehicle computer are required. We there- fore strongly recommend you make use of the training offered by SICK AG on the Hamburg site.
Integration of the NAV350 in a navigation system Overview of the integration of the NAV350 in the control system for an AGV The vehicle computer informs the NAV350 of the actual velocity and rate of turn of the AGV from its odometry (see fig.
The internal time stamp in the NAV350 is added to the measured data from the NAV350. The internal time stamp in the NAV350 is a 32-bit counter that counts up by 1 every 1 ms. To synchronise the internal time in the NAV350 with the system time in the vehicle’s control system, the NAV350 provides three options.

3.9.6 Result Port The NAV350 features a Result Port, a simplyfied telegramme with its own port. The Result Port supplies landmark data and scan data parallely to the CoLa dialect. The Result Port can be configured via the SOPAS user interface. Alternatively, the Result Port may also configured using the CoLa diagrammes.
For the NAV350 the mounting kit part no. 5311055 with mounting material is available. As an alternative you can use a strong stable mounting bracket that provides adjustable alignment of the NAV350 in the X- and Y axis. The NAV350 weighs approx. 2.4 kg (5.29 lb). 8013889/ZML0/2017-06-09...
3.10.3 Distance between NAV350 and the object/surface to be measured The measurement area on the NAV350 starts at 0.5 m (1.64 ft) in front of the optics (light output window). To prevent false measurements, in the case of the recessed installation of the NAV350 the increase in the size of the laser beam with increasing distance is to be taken into account.
In this way the origin and axes for the absolute coordinate sys- tems are defined. In this coordinate system the NAV350 determines its absolute position in the X and Y direc- tion including the angular position α of its local coordinate system in relation to the abso- lute coordinate system.
The maximum scanning range of the NAV350 is 70 m (229.66 ft) onto reflectors. It is possible to deter- mine the minimum reflector heights based on the characteristics of the floor and the meas- urement distance.
3.10.6 Reflector placements Reflector placements are to be planned such that the NAV350 has a clear view of at least 3 reflectors in every position. A clear view of 4 to 5 reflectors is recommended to ensure reliable positioning even in the case of the operation of several AGV. As far as possible the same number of reflectors should be fitted to both sides of the route.

2 reflectors must not be more than 120°. • At positions at which the NAV350 is placed on the route, there must be at least 4 to 6 reflectors in the measurement area of the NAV350. Also the angle between 2 reflectors must not be more than 120°.
Division of the route into layers The reflector data saved in the NAV350 can be allocated to up to 320 layers in groups. Each layer represents a fixed defined area in the AGV’s overall route through which the AGV pass- es.

The NAV350 must be commissioned only by adequately qualified personnel.

The interactive configuration is carried out using SOPAS ET. Using this configuration soft- ware, you can configure and test the measurement properties, the analysis behaviour and the output properties of the NAV350 as required. The configuration data can be saved as a parameter set (project file) on the PC and archived.
Once the configuration has been completed, the parameter set must be saved in non-vola- tile memory in the NAV350. In addition, the parameter set should be saved as a project file (spr file with configuration data) on the PC and archived.
