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).
