## **Theory of Operation** 

A short electrical pulse drives a semiconductor laser diode to emit a pulse of light. The emitted light is collimated through a lens, which produces a very narrow laser beam. The laser beam bounces off the target, scattering some of its light through the sensor’s receiving lens to a photodiode, which creates an electrical pulse. The time interval between the two electrical pulses (transmitting and receiving the beam) is used to calculate the distance to the target, using the speed of light as a constant. 

Multiple pulses are evaluated by the sensor’s microprocessor, which calculates the appropriate output value. The analog output provides a variable signal (4 mA to 20 mA or 0 V dc to 10 V dc, depending on model) that is proportional to the target’s position within the user-programmed analog window limits. The discrete (switched) output energizes whenever the target is located between the user-programmed discrete window limits. Window limits for the analog and discrete outputs may be the same, or they may be programmed independently.

> 2 To order the 9 m cable models, add the suffix W/30 to the model number of a cabled sensor. For example, LT3PULV W/30. A model with a QD-connector requires a mating cable.

_Figure 1. Theory of Operation_ 

## **Configuration Instructions** 

## **Sensor Power-Up and Laser-Enable** 

Power up the sensor for 30 minutes to allow the sensor’s internal temperature to stabilize before operating or attempting to program the sensor. If the sensor is used in applications where the temperature is several degrees higher or lower than the ambient temperature, allow the sensor to stabilize in that condition before programming the window limits. The range decreases when the sensor warms up. 

The Laser-Enable feature allows the sensor to be continually powered and enabled only when being used. This eliminates the need for the extended warm-up period between uses. 

The sensor’s red Signal LED indicates the condition of the received signal from the object being measured. When programming the window limits, this LED must be on (not flashing) for the sensor to accept the setting. To ensure the received signal will not be marginal during operation, move the target object 300 mm beyond the furthest desired switch point during setup and verify the signal LED is still on.

**Signal LED** (red)—Indicates the strength and condition of the sensor’s incoming signal. 

**Signal LED Status Indicates** On Good signal Off No signal is received or the target is beyond the range limitations of the sensor (with some tolerance beyond the recommended minimum and maximum sensing distance) Flashing Marginal signal strength (cannot teach limits) ~~————~~ **Response Speed** Before setting window limits, use the sensor’s speed button to toggle between the three response speed settings. The selected speed will be indicated by one of the three response speed indicator LEDs. **Discrete Output Response Speed Analog Output Frequency Response (-3dB)** Slow 100 ms ON and OFF 2.5 Hz (192 ms average/1 ms update rate) Medium 10 ms ON and OFF 10 Hz (48 ms average/1 ms update rate) Fast 1 ms ON and OFF 114 Hz (6 ms average/1 ms update rate) ~~————~~ **Programming Remote Programming** —To program the sensor remotely or to disable the keypad, use the Remote Programming function. Disabling the keypad prevents accidental or unauthorized adjustment of the programming settings. Connect the yellow wire of the sensor to +5 V dc to 24 V dc, with a remote programming switch connected between them. 

**Note:** The impedance of the remote teach input is 55 kΩ. 

Programming is accomplished by following the sequence of input pulses. The duration of each pulse (corresponding to a push button “click”) and the period between multiple pulses are defined as “T”: 0.04 seconds ≤ T ≤ 0.8 seconds. 

**Analog Output Slope** —The L-GAGE LT3 Sensor may be programmed for either a positive or a negative output slope, based on which condition is taught first. If the near limit is taught first, the slope will be positive. If the far limit is taught first, the slope will be negative. Banner’s unique scalable analog output (patent pending) automatically distributes the output signal across the width of the programmed sensing window. 

In the event of analog signal loss for longer than 2 seconds, the analog output goes to 0 V dc or 3.6 mA, which may be used to trigger an alarm.

_Figure 2. Analog Output as a Function of Target Position_ 

**Note:** The linear analog output tracks slightly past each window limit (from 3.8 mA to 20.5 mA). 

## **Teaching Limits for Background Suppression** 

For some applications, ignoring objects beyond a certain distance may be required. To suppress the background, place a target object at the selected distance, and teach the position twice. The sensor’s discrete output will activate when an object is detected between the sensor’s minimum sensing distance and the taught position. 

**Note:** The sensor allows for some forgiveness in this procedure. If the two limits are not exactly the same (but less than 20 mm apart), the sensor will put the set point at the “average” of the two limits. 

Program either analog output or discrete output first. For the button or the remote wire, a button click or pulse is: 0.04 seconds ≤ T ≤ 0.8 seconds.

## **Teaching Independent Limits for Either Output** 

**Teaching Analog Limits Using the Auto-Zero Feature (Analog Output)** —For some analog applications, a sensing distance switch point centered within a sensing window may be required. The TEACH procedure is simple: teaching the same limit twice causes the sensor to program a window centered on the position taught. This window is 10 m wide (taught position ± 5 m). 

To exit Program mode without saving changes, press and hold the same push button (or hold the remote line high) for longer than 2 seconds (before teaching the second limit). The sensor will revert to the last saved program. 

1. Enter programming mode. 

|**Method**|**Acton**|**Result**|
|---|---|---|
|**Push Buton**|Push and hold the buton for either output for longer than 2 seconds. The sensor will return to<br>RUN mode if frst TEACH-conditon is not registered within 120 seconds.|The appropriate TEACH-LED turns ON. The sensor is<br>waitng for frst limit.|
|**Remote Input**|No acton required.||

## 3. Teach the second limit. 

4. Program the second output by repeating steps two and three. 

## **Teaching Identical Limits to Both Outputs** 

When teaching limits simultaneously, both the outputs will have identical limits. 

To exit Program mode without saving changes, press and hold the same push button (or hold the remote line high) for longer than 2 seconds (before teaching the second limit). The sensor will revert to the last saved program. 

1. Enter programming mode. 

|**Method**|**Acton**|**Result**|
|---|---|---|
|**Push Buton**|Push and hold the buton for either output for longer than 2 seconds. The sensor will return to<br>RUN mode if the frst TEACH conditon is not registered within 120 seconds.|The appropriate TEACH LED turns ON.|

## **Enabling or Disabling the Push Button** 

In addition to its programming function, the remote line may be used to disable the push buttons for security. Disabling the push buttons prevents undesired tampering with the sensor configuration settings. 

1. Connect the sensor’s gray wire. 

2. Four-pulse the remote line to enable or disable the push button. 

The sensor toggles between enable and disable settings and returns to RUN mode.
