3.5 First steps without LRF Interface Kit LRF modules can be connected to your PC without an interface cable provided by Safran Vectronix. In this case we recommend reading this manual carefully before using the LRF module. Please be aware of the risk of wrong pin-connection or destroying the module by applying overvoltage and other errors.

Vibration and shock outside the specified values can destroy or shift parts inside the LRF in a way that renders the LRF unusable. 914929_TML_LRF7047_en_Version B Public: 04.2019 Confidential & Proprietary Safran Vectronix AG – All rights reserved Page: 22/72...
4.4.1 Mounting the LRF module with detached Laserbox In order to mount and operate the LRF 7047 with a detached Laserbox follow the steps below: 1. The LRF module must be unplugged 2. Loosen both screws (A) with a T5 screwdriver and remove the flexcable protective cover 3.
4.5 Boresighting The module receiver and transmitter are boresighted in the factory. For this reason, the module can be mounted and replaced easily. LRF 7047 offers two wavelengths for boresighting. 4.5.1 Boresighting at 1550 nm For a professional boresighting of the LRF module with the main optical axis of the host system, we recommend the use of a collimator and a camera sensitive to the 1’550 nm wavelength of the laser...
However, this only works when the card is quite close to the LRF module. To see the laser beam of LRF 7047 modules, the laser viewing card must absorb light of 1550 nm wavelength (or 830 nm if the optional pointer is available).
The yellow pieces of tape stop dust penetrating the optical system and shall be removed just before the host system is sealed and purged. 914929_TML_LRF7047_en_Version B Public: 04.2019 Confidential & Proprietary Safran Vectronix AG – All rights reserved Page: 26/72...

The tilt angle influences LRF range performance, being 0° angle the optimal value. NOTICE The tilt angle prevents the pointer from creating ghost images. 914929_TML_LRF7047_en_Version B Public: 04.2019 Confidential & Proprietary Safran Vectronix AG – All rights reserved Page: 28/72...
Implementation of laser safety measures is the system integrator’s responsibility. The LRF 7047 provides a hardware interlock function to ensure that the pointer is not switched- on unintentionally. To emit a non-eye safe laser beam, the LRF 7047 has to be powered correctly, woken-up, the interlock pins need to be short-circuited and the pointer software command has to be sent via the serial interface.
4.9 Deflection area of Double Stage Fiber Laser NOTICE The double stable fiber laser of LRF 7047 is equipped with shock absorbing elements to withstand pyro shock impacts up to 800 g. These shock impacts can cause a deflection of the double stage fiber laser of 5 mm in X, Y and Z direction.
