ipf electronic OT15 Series Manual

OT15 series
Diffuse-reflection sensors

Installation and environment

Coatings on the optics impair the function. Please install the device in such a way that no dust can be deposited or
liquids can get onto the optics. The device should be accessible for cleaning.
From time to time the optics should be cleaned with a soft cloth moistened with alcohol or soapy water.

Cable

The PVC connecting cable of the fixed cable devices is not suitable for environments containing oil or solvents or for
applications in which the cable is frequently moved.
In such cases the use of a connector device with an ipf-Sensorflex cable socket is recommended.

Adjustment

With the built-in potentiometer the sensitivity and thus the switching distance can be changed. When delivered the
device is set to the maximum value. The switching distance is reduced by turning it counterclockwise. The full adjust-
ment range of the potentiometer is 12 turns.
Safe operation is ensured if the output switches (light-on mode) when the object is detected and the green function
LED lights up in addition to the yellow switching status LED.
If only the yellow LED lights up when the output is switched, either the sensitivity is set too low, the selected switching
distance is too large, or the optics are dirty.
When the green LED lights up, the alarm output of the OT150700 and OT150770 versions is switched on simultaneously.

Note

The devices react to the intensity of light reflected from any object. The specification of the nominal switching distances
is based on white paper with a surface of 200 x 200mm. With more reflective materials (e.g. polished aluminum) the
maximum switching distance increases. With low reflective materials (e.g. black rubber) the nominal switching distance
cannot be reached by far.
