preset phototransistor output level is reached.
At this time, the LED drive current is locked and maintained until
the calibration pin is grounded. If for some reason the LED drive cur-
rent reaches the maximum allowable value, a RED warning light will
turn on. During the calibration process, remote monitoring of J1-Pin
5 allows the designer to ensure the system is calibrated (this output
should be at the preset calibrated output level of 1/2 Vcc when the
calibration procedure is completed). Adjusting the phototransistor
load resistor may allow the system to calibrate properly.
After the calibration process is complete, the device is ready for
acknowledgement of a change in the signal. The design engineer
6
can monitor either the Analog Output (J1-Pin 5) or Logical Output
(J1-Pin 2 or J1-Pin 3).
Connection of the analog ouput to additional circuitry allows the
design engineer to set any reference point to recognize an optical
change for the device being monitored. The Analog Output can be
used with reflective devices to monitor small changes in the distance
from the device.
The Logical Output will change state once the preset optical light
condition is reached. Logic Out A” (mating connector orange wire)
switches when the optical output signal decreases below approxi-
mately 1/3 of Vcc while “Logic Out B” (mating connector blue wire)
switches when the optical output signal increases above approxi-
mately 2/3 of Vcc.
As with all optical devices with logic outputs, the switching condition
is consistent with the phototransistor receiving a preset light level.
