Basic TEACH Instructions
Use the following instructions to teach the Q5X 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.
4. Complete these steps only if it is required for the selected TEACH mode.
a) Present the second target.
b) 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 analog teach —Sets the distance values associated with 0V and 10V (4mA and 20mA) based on taught
target distances
• One point analog teach —Sets the 5V (12mA) midpoint of the analog output to center the analog output around a
reference target position
• Two-point static background suppression (discrete, channel 2 only)—Two-point TEACH sets a single switch point.
The sensor sets the switch point between two taught target distances.
• Dynamic background suppression (discrete, channel 2 only)—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) (discrete, channel 2 only)—One-point window sets a window (two
switch points) centered around the taught target distance.
• One-point background suppression (discrete, channel 2 only)—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 (discrete, channel 2 only)—Dual mode records the distance and amount of light received
from the reference surface. See Dual Mode Reference Surface Considerations on p. 11 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 selected channel displays briefly, then 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, 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, 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.
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.
• —The switch point value can be changed by teaching or manual adjustment, but no sensor settings can be changed
through the menu.
Note: When the sensor is in either or mode, the active channel can be changed using (+)(CH1/
CH2).
