How to clean the window in the scanner head on the NAV350:
1. Switch off the NAV350 while performing cleaning, as otherwise the scanner head will
rotate.
2. Use a clean and soft brush to remove dust from the window.
3. Then wipe off the optics using a clean and damp cloth.
Important If the optics are scratched or damaged (crack, fracture), the optics must be replaced. Con-
tact SICK service.
7.2 Exchanging a NAV350
As all external cable connections end in the plug connectors, it is not necessary to re-install
the device electrically on a device replacement. The replacement unit can then be simply
connected.
If the NAV350 is to be replaced, proceed as follows:
1. Switch off the voltage supply for the NAV350.
2. Remove the connection cables from the NAV350.
3. Mounting the replacement device (see chapter 4 “Mounting” on page 43).
4. Open project file (spr file with configuration data) using SOPAS ET and transfer configu-
ration to the device (see fig. 33 on page 55).
