5 INSTALLATION
To obtain the maximum reliability of detection it is necessary to effect a correct installation of the
detector, taking into account the field of measurement, the minimum dimension of the material as a
function of distance, and applying the precautionary measures reported here below.
5.1 S AFETY
The ID2202 photodetectors are intrinsically safe devices because they operate at a low voltage and do
not have dangerous parts. However, they should be used and maintained only by skilled personnel
who are fully acquainted and comply with all the instructions contained in this manual.
5.2 T RANSPORT
All parts of the photodetector are transported in a box. Inside the box there are suitable polystyrene
compartments for the safe transport of the device. The package should be kept so as to be used for
transport in case of extraordinary maintenance or repair.
5.3 P OSITIONING
The distance between the photodetector and the material to detect must be determined following the
indications given in the diagram of fig. 7.
In the diagram, for SSEL = OFF (SENS = HI, HIGH sensitivity) and SSEL = ON (SENS = LOW, LOW
sensitivity) respectively, lines represent the maximum installation distance based on different
diameters of the rolled product.
The diagram gives the value of the permissible maximum installation distance for the operator,
according to the estimated or measured temperature of the material.
ATTENTION !
The diagram gives the maximum distance of use. We recommend to install the HMD at a lower
distance than the maximum allowed, for ex. at 60% so as to maintain an adequate margin of safety for
detection.

On the contrary, when rolling hot products, with a very short distance the photodetector may become
overheated.
Example
The ID2202 must be installed to detect a material with minimum temperature of 480°C, and a minimum
dimension of 10mm. What is the ideal distance for installation?
Should ID2202 detect “low” temperatures, it must be set with high sensitivity (SENS = HI).
In the diagram, curve corresponding to D=10, shows a maximum distance of about 800mm.
The ideal distance for installation should be less than 60% the maximum distance, for instance
480mm.
