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 6. 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.

Mount the Device

1. If a bracket is needed, mount the device onto the bracket.
2. Mount the device (or the device and the bracket) to the machine or equipment at the desired location. Do not tighten the
mounting screws at this time.
3. Check the device alignment.
4. Tighten the mounting screws to secure the device (or the device and the bracket) in the aligned position.

1 Applying tilt to sensor may improve performance on reflective targets. The direction and magnitude of the tilt depends on the application, but a 15° tilt is often sufficient.

Cleaning and Maintenance

Clean the sensor when soiled and use with care.
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 only 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

 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 —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 —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) —One-point window sets a window (two switch points) centered around
the taught target distance.
• One-point background suppression —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 —Dual mode records the distance and amount of light received from the reference surface.
See 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 or one time. The current switch point value flashes slowly.

2. Press 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 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.
3. Press SELECT to change the output configuration and return to Run mode.

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:
• —The sensor is unlocked and all settings can be modified (default).
• — The sensor is locked and no changes can be made.

Q4X Stainless Steel Laser Sensor

• —The switch point value can be changed by teaching or manual adjustment, but no sensor settings can be changed
through the menu.

When in mode, displays when the (SELECT)(TEACH) button is pressed. The switch point displays when (+)(DISP)
or (-)(MODE) are pressed, but displays if the buttons are pressed and held.

When in mode, displays when (+)(DISP) or (-)(MODE) are pressed and held. To access the manual adjust options,
briefly press and release (+)(DISP) or (-)(MODE). To enter TEACH mode, press the (SELECT)(TEACH) button and hold for longer
than 2 seconds.

To enter mode, hold and press four times. To enter mode, hold and press seven times. Holding
and pressing four times unlocks the sensor from either lock mode and the sensor displays .

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 non-ideal 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.
