6. CALIBRATION PROCEDURE

The calibration procedure sets the signal level that arrives from the

receiver in the rest condition (no object detection).

In every other condition, the acquired signal will be compared to the

one acquired during the calibration.

The calibration depends on the alignment and distance of the two

units; the procedure must be repeated every time these parameters

change.

6.1. Correct calibration procedure guide

The calibration can be done according to the following procedure, once

the mechanical mounting, electrical connections and alignment are

completed:

• Switch ON the DS3.

• In the CALIBRATION AT POWERING mode (see function 4 in

Tab.1 at page 14), the system will automatically calibrate itself at

the powering on. Successive calibrations during functioning have to

be made according to the following mode.

• In the MANUAL CALIBRATION mode (see function 3 in Tab.1 at

page 14), press and release the SET pushbutton.

The calibration phase can have a variable duration and ends when

the green LED lights up in a steady manner; the system functions

only at this moment.

• No undesired object should be present in the detection area during

the calibration process. The calibration procedure can be made

even i f an object will remain fixed inside the detection area (e.g.

support, paper etc). In this case, area affecting the fixed object will

be excluded from the total sensitive area (BLANKING mode).

The powering on of the red LED (ERROR FAILURE) indicates this

particular situation.

• The position of both the receiver and emitter must remain the same

both during and after calibration (the use of specific anti-vibration

brackets are suggested in case of particularly critical applications

characterised by strong vibrations).
