► Bright extraneous light such as e.g. sun light incident on the surface of the object of
interest or on the camera lens should be avoided. Only the infrared portion of the light be-
tween 800nm and 900nm is critical and should not exceed the sunlight-equivalent of 8klux.
► The camera optics must be kept clean. Avoid installation in heavy polluting areas of a
machine. Mounting the camera facing down may help to reduce collection of dust on the
front window.
► Do not install the camera behind windows. Direct reflection from the camera illumination
back into the camera lens may lead to measurement errors. Such reflections are present
even at very clean glass surfaces.
4.3 Heat dissipation
ATTENTION
Depending on the operating mode, the unit may heat up.
The difference between the unit's surface temperature and the ambient temperature may
not exceed 25 degrees. Take one or several of the following measures:
► Preferably mount camera to large metal parts which are good heat conductors such as
e.g. aluminium. A good thermal contact between camera and camera mounting increases
the dissipation of excess heat. A heat conducting plate is available as separate accessory.
► Allow the circulation of air around the camera to allow thermal convection. Mounting
positions directly under a roof or in cramped areas may lead to heat accumulation.
► Thermal convection may be further improved by using one or two heat dissipators which
are available as separate accessories.
► The camera temperature may also be reduced by reducing the following operation pa-
rameters of the camera:
- frame rate
- exposure time
- maximum measurement distance (number of used frequencies)
► Use a contact protection.
