The TBT/TBR-600-40 is primarily a Thru-Beam sensor consisting of one transmit and one receive transducer, in separate and self contained housings. It can count up to 200 objects per second, as they pass through its ultrasonic beam, from 0 to 40 inches. The sensors can also be mounted in a Reflective position to detect targets. The Thru-Beam and Reflective mounting options provide the user with simple and accurate ways to detect the presence of various objects. An adjustable Delay control is added to vary the output re-sponse of the solid state relays to the time, or count rate, of a moving target. An adjustable Sensitivity control is added to provide highly accurate target detection. P1 on the receiver (TBR) is labeled sensitivity adjustment. The LED is pro-vided to show signal strength. The sensor is factory set with P1 fully clockwise (cw), making the LED solid red in color.

When P1 is fully counterclockwise (ccw), the LED will be solid green in color. After positioning the sensors at the required distance, a typical adjustment is performed by turning P1 ccw, causing the LED to change from a solid red to a mostly red condition. The unit is now properly adjusted. To achieve greater sensitivity for smaller targets, turn P1 ccw so that the LED will be more green in color. To make the sensors less susceptible to heavy dirt build up, turn P1 cw so that the LED will be brighter red in color.

SENSITIVITY

Adjustable sensitivity is provided to accurately detect the distance of the target, by use of the P1 control potentiometer. To adjust, position the sensors in the desired locations. P1 should be fully counter clockwise, for the minimum sensitivity. In this position the LED will be in the green, or no detect state. Turn P1 slowly clock- wise until the LED changes in color to a red yellow combination, and remains stable. In this state the sensors will provide the best detec-tion of the desired target, and will not be affected by an adjacent target.

DELAY

Adjustable delay is provided to vary the response of the solid state relay outputs, in relationship to time or the count rate of a moving target, by use of the P2 control potentiometer. P2 fully counter clockwise provides the fastest response time, and P2 fully clockwise provides the slowest response time. See the specification page under Response Time and/or Count Rate for more detail. The adjustment proceedure is performed simply by turning P2, counter clockwise (faster) or clockwise (slower), to respond appropriately to the speed of the targets moving past the sensors detection point.

THRU-BEAM/ REFLECTIVE

Figure A shows the transmit and receive sensors mounted for a Thru-Beam application. Figures B and C show the transmit and receive sensors mounted for a Reflective application. The TBT/ TBR-600-40 sensors can be used effectively for both sensing applications. The adjustment pro-ceedures for sensitivity, delay, and count rate, pertain to both the Thru-Beam and Reflective type of mounting or sensing applications.
