IR LED calibration and settings
The IR01 board installed inside the IR LED illuminator is equipped with four LEDs. The DL1
LED (green) is on when the board is correctly powered. The DL2 LED (yellow) is on when the
IR LEDs are interrupted (open-led). The DL3 LED (red) is on when the IR LEDs are not
activated or when the IR LEDs are in short-circuit if activated. The DL4 LED (yellow) is on
when the IR LEDs are in the activation phase during its hysteresis delay-time.
S1 button is used for manual IR LEDs activation test.
TR3 trimmer is used for adjusting the sensitivity of the light sensor photocell.
Counter clockwise rotation decreases sensitivity. Clockwise rotation increases it.
Setting it to 0 disable the activation from light sensor photocell.
J6 jumper is used for instant or delayed IR LEDs Activation.
Connection between 1 and 2 triggers on hysteresis delayed activation and deactivation (in this
case, DL4 shows the delayed phase). Connection between 2 and 3 triggers on instant
activation and deactivation (in this case, DL4 is always OFF).
