MATP – presence of material

The MATP digital output is activated when an infrared source of intensity sufficient to exceed the

detection threshold, which is determined by the sensitivity selection ("coarse" control) and the position

of potentiometer ("fine" control), is detected.

HEALTHY – reliable detection

The HEALTHY digital output is normally activated and deactivated when one of the anomalies

indicated below is present:

the IR signal received is near the threshold, and therefore the detection is uncertain

the TEST input is activated but the IR sensor does not detect a sufficient signal

internal overheating

absence of power supply

Simultaneously with the deactivation of the HEALTHY output, the anomaly is indicated also by the two-

colour LED located on the rear of the ID2202.

TEST – self-test

When enabled, an IR LED located in front of the sensor is switched on, causing the MATP output to

activate.

SSEL – sensitivity selection

It is possible to select the "coarse" sensitivity of the detector ID2202 by activating or not the SSEL

digital input, that is to say connecting it or not to the power supply.

The potentiometer located on the rear panel provides the fine control.

The SSEL input may be:

reported on an external clamp with a configuration jumper

piloted by a PLC output, to set dynamically the sensitivity according to the temperature of the

material to detect.

Note that, if the SSEL input is not connected, the sensitivity selected is HIGH.

ATTENTION !

It is necessary to set the sensitivity on HIGH if the temperature of the material is near the lower

measurable limit.

We recommend not using the HIGH selection if not necessary, given that it increases the probability of

detection of sources outside the process (reflections of material or solar radiation).
