Installation and Assembly
i
As the sensor (optical fiber) consists of a glass fiber bundle with several individual fibers, a break in the illu-
mination fibers causes a drop in the illumination intensity, and a reduced measurement signal of the signal fi-
bers. Fiber breakage leads to a loss in the measuring sensitivity up to complete loss of the measuring signal.

Please observe the permissible minimum bending radius of the integrated optical fiber.
Failure to observe the minimum bending radius (depending on the sensor model) leads to breakage of
the integrated optical fiber.
Replace the sensor only with the light source switched off to prevent dazzle.
