Installation

Mount the Sensor

Mount the SLU4 directly and securely using the clearance holes on the side of the sensor (bolts not included).

To lessen the effects of web ﬂutter, position the bottom fork of the sensor slightly above the path of the web so that the web can glide over the

bottom of the fork with slight tension.

Sensor Setup

Use the following images and instructions to program the sensor for use.

The default TEACH mode is Gap TEACH.

Gap TEACH

The sensor sets a threshold based on the gap between two labels.

1. Place the label web so that it is centered on the arrow.

Optical Path

Alignment Mark

2. Position the gap between the labels in the center of the sensor using the alignment line as shown.

When viewing from the top of the sensor, use the output LED to center the gap between the labels.

Note: For a simpler TEACH, remove one label to create a larger gap.

3. Place label webbing so that it slides along the bottom of the sensor gap plate.

This ensures a more consistent setup and performance.

4. Press and hold the TEACH button for 2 seconds.

The display shows "Gap Set", then returns to Run mode.

The + and - buttons can be used to manually ﬁne tune the sensor to the application.

Sensor Menu

Access the menu from run mode by pressing and holding MODE for 2 seconds.

Use +and –buttons 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 End and press SELECT.

The following are menu options:

Adaptive Tracking

Evaluates signal levels and makes automatic adjustments to keep the sensor in optimum response levels.

Output Mode

Change from GAP ( ) to LABEL ( ). GAP means the output will be on when the label is not present under the transducer. LABEL

means the output will be on when the label is under the transducer.

= Outputs on the Label

= Outputs in the Gap

Display Orientation

Toggles the orientation of the display.

Timer Mode

Selects the output timing delay to be set:

Off Delay—Outputs stay on for set time after duration of input.

On Delay—Outputs turn on when input exceeds set time.

One Shot—Outputs turn on for set time when triggered by input.

Debounce—Output changes immediately when a change in detect state occurs. Then, a timer prevents the output from switching

again until the timer expires. This behavior occurs on both the leading and trailing edges of the object.

Timer Value

Sets the delay timer. This menu item is available only if a Timer Mode has been selected. The range is 1 ms to 9999 ms.

Button Lockout

Locks the sensor for tamper-free operation.

The sensor can be taught if it is locked. To unlock the sensor, toggle from Lock ( ) to Unlock (no symbol).

Scope

Allows the operator to visually inspect the current setup for repeatability. The sensor scope also reveals any nominal setup issues or

sensitivities to label or gap thickness changes. To shorten the time between signals, press +. To lengthen the time between signals, press

–.

Input Active (SLU4-PN-2M and SLU4-PN-Q8 models only)

Sets the remote input to either Active High or Active Low to dictate the type of signal needed to program the sensor remotely. For more

details, see Remote Input on page 4.

Input/Output (SLU4-BM-Q7 model only)

Sets the output to either NPN or PNP. Also sets the remote input to either Active High or Active Low to dictate the type of signal needed to

program the sensor remotely. For more details, see Remote Input on page 4.

End

Returns to run mode.

Factory Reset

Resets the sensor to factory defaults.

Remote Input

Use the remote input to program the sensor remotely.

The remote input provides limited programming options. The remote input is either Active High (PNP) or Active Low (NPN) depending on the Input

Active setting. For Active High (PNP), connect the white wire to 24 V DC with a remote switch connected between the wire and 24 V DC. For Active

Low, connect the white wire to ground (0 V DC) with a remote switch connected between the wire and ground. Pulse the remote input according to

the diagram and the instructions provided in this manual.

The length of the individual programming pulses is equal to the value T: 0.04 seconds ≤ T ≤ 0.4 seconds.

Remote Input Signals

Note: Waveforms shown correspond to PNP input mode.

Figure 10. Gap Set

Pulse once, 40 ms to 400 ms.

Figure 11. Label Set

Pulse twice, 40 ms to 400 ms, with 40 ms to

400 ms idle time between pulses.

Figure 12. Dynamic Set

Hold the remote input on for more than 750 ms,

while pulling the labels and gaps through the

sensor, then release the remote input line. The

sensor returns to Run mode.
