Q4X Stainless Steel Laser Sensor
## **Sensor Orientation**
Optimize detection reliability and minimum object separation performance with correct sensor-to-target orientation. To ensure reliable detection, orient the sensor as shown in relation to the target to be detected.
_Figure 5. Optimal Orientation of Target to Sensor_
See the following figures for examples of correct and incorrect sensor-to-target orientation as certain placements may pose problems for sensing some targets. The Q4X can be used in the less preferred orientation and provide reliable detection performance; refer to the _Performance Curves_ for the minimum object separation distance required for each case.

## **Cleaning and Maintenance**
Handle the sensor with care during installation and operation. Sensor windows soiled by fingerprints, dust, water, oil, etc. may create stray light that may degrade the peak performance of the sensor. Blow the window clear using filtered, compressed air, then clean as necessary using water and a lint-free cloth.
## **Sensor Programming**
Program the sensor using the buttons on the sensor or the remote input (limited programming options).
In addition to programming the sensor, use the remote input to disable the buttons for security, preventing unauthorized or accidental programming changes. See the Instruction Manual, p/n 181483 for more information.
## **Setup Mode**
Access Setup mode and the sensor menu from Run mode by pressing and holding **MODE** for longer than 2 seconds. Use and to navigate through the menu. Press **SELECT** to select a menu option and access the submenus. Use & and © to navigate through the submenus. Press **SELECT** to select a submenu option and return to the top menu, or press and hold **SELECT** for longer than 2 seconds to select a submenu option and return immediately to Run mode.
To exit Setup mode and return to Run mode, navigate to
and press **SELECT** .

Q4X Stainless Steel Laser Sensor
## **Basic TEACH Instructions**
Use the following instructions to teach the Q4X sensor. The instructions provided on the sensor display vary depending on the type of TEACH mode selected. Two-point TEACH is the default TEACH mode.
1. Press and hold **TEACH** for longer than 2 seconds to start the selected TEACH mode.
2. Present the target.
3. Press **TEACH** to teach the target. The target is taught and the sensor waits for the second target, if required by the selected TEACH mode, or returns to Run mode.
Complete steps 4 and 5 only if required for the selected TEACH mode:
4. Present the second target.
5. Press **TEACH** to teach the target. The target is taught and the sensor returns to Run mode.
See the Instruction Manual for detailed instructions and other available TEACH modes. The TEACH modes include:
- Two-point static background suppression rTrepa —Two-point TEACH sets a single switch point. The sensor sets the switch point between two taught target distances, relative to the shifted origin location.
- Dynamic background suppression maee —Dynamic TEACH sets a single switch point during machine run conditions. The sensor takes multiple samples and the switch point is set between the minimum and the maximum sampled distances.
- One-point window (foreground suppression) rer —One-point window sets a window (two switch points) centered around the taught target distance.
- One-point background suppression one —One-point background suppression sets a single switch point in front of the taught target distance. Objects beyond the taught switch point are ignored.
- Dual intensity + distance mar —Dual mode records the distance and amount of light received from the reference surface. See _Dual Mode Reference Surface Considerations_ on page 10 for more information about selecting a reference surface. The output switches when an object passing between the sensor and the reference surface changes the perceived distance or amount of returned light.
## **Manual Adjustments**
Manually adjust the sensor switch point using the & and © buttons.
1. From Run mode, press either wo or & one time. The current switch point value flashes slowly.
2. Press w& to move the switch point up or & to move the switch point down. After 1 second of inactivity, the new switch point value flashes rapidly, the new setting is accepted, and the sensor returns to Run mode.
**Note:** When FGS mode is selected (FGS indicator is on), manual adjustment moves both sides of the symmetrical threshold window simultaneously, expanding and collapsing the window size. Manual adjustment does not move the center point of the window.
**Note:** When dual mode is selected (DYN, FGS, and BGS indicators are on), after the TEACH process is completed, use the manual adjustment to adjust the sensitivity of the thresholds around the taught reference point. The taught reference point is a combination of the measured distance and returned signal intensity from the reference target.
Manual adjustment does not move the taught reference point, but pressing increases the sensitivity, and
pressing oS decreases the sensitivity. When re-positioning the sensor or changing the reference target, re-teach the sensor.
## **Light Operate/Dark Operate**
The default output configuration is light operate. To switch between light operate and dark operate, use the following instructions:
1. Press and hold **LO/DO** for longer than 2 seconds. The current selection displays. 2. Press **LO/DO** again. The new selection flashes slowly.
- Press **SELECT** to change the output configuration and return to Run mode.
3.
**Note:** If neither **SELECT** nor **LO/DO** are pressed after step 2, the new selection flashes slowly for a few seconds, then flashes quickly and the sensor automatically changes the output configuration and returns to Run mode.
## **Locking and Unlocking the Sensor Buttons**
Use the lock and unlock feature to prevent unauthorized or accidental programming changes. Three settings are available:
- LokyoLa —The sensor is unlocked and all settings can be modified (default).
-
- The sensor is locked and no changes can be made.

## **Dual Mode Reference Surface Considerations**
Optimize reliable detection by applying these principals when selecting your reference surface, positioning your sensor relative to the reference surface, and presenting your target. The robust detection capabilities of the Q4X allows successful detection even under nonideal conditions in many cases. Typical reference surfaces are metal machine frames, conveyor side rails, or mounted plastic targets. Contact Banner Engineering if you require assistance setting up a stable reference surface in your application. For detailed instructions for detecting clear or transparent objects, refer to the Instruction Manual, p/n 181483.
1. Select a reference surface with these characteristics where possible:
- Matte or diffuse surface finish
- Fixed surface with no vibration
- Dry surface with no build-up of oil, water, or dust
2. Position the reference surface between 50 mm and the maximum sensing range for threaded barrel models or between 60 mm and the maximum sensing range for flush mount models.
3. Position the target to be detected as close to the sensor as possible, and as far away from the reference surface as possible.
4. Angle the sensing beam relative to the target and relative to the reference surface 10 degrees or more.
