Ultrasonic Clear Label Sensor (Model CLS-1)

Specifications

Note: RoHS Compliant. Product subject to change without notice.

Connections and Dimensions

The sensor is available in M12 and M8/M8LE models, with either a connector or a 6' (1.8m) shielded cable.

Wiring Configurations:

• M12 5-Pin Connector: Brown (1) - Positive, White (2) - NPN, Blue (3) - Negative, Black (4) - PNP, Gray (5) - Remote AUTOSET.
• M8 4-Pin Connector: Brown (1) - Positive, White (2) - Remote AUTOSET, Blue (3) - Negative, Black (4) - Output.
• M8LE 4-Pin Connector: Brown (1) - Positive, White (2) - NPN, Blue (3) - Negative, Black (4) - PNP.

Output Configuration Notes:

• NPN (Sinking) Output: Load terminated to positive. Input activated by connecting to negative.
• PNP (Sourcing) Output: Load terminated to negative. Input activated by connecting to positive.

Dimensions:

Detailed diagrams show physical dimensions for M12 and M8/M8LE models. Key dimensions include overall height, width, and mounting hole locations. For example, M12 models are approximately 4.522" [114.86mm] in height, while M8/M8LE models are approximately 4.181" [106.20mm] or 4.332" [110.03mm] in height.

Installation Manual

Setup Instructions

The sensor features an OLED Graphic Display and three pushbutton controls.

• Display Elements: Contrast Indicator, Label Position indicator, Signal Strength indicator, Threshold Number display, Output ON indicator (for Gap or Label), and AUTO Adjust Mode indicator.

Simple Setup

Gap AUTOSET: Place the label gap in view. Press and hold the AUTOSET/GAP button for two seconds. "Gap Set" will be displayed, indicating a successful setup.

Label AUTOSET: If false triggers occur, place the label in view. Push and hold the AUTOSET/LABEL button for two seconds. "Label Set" will be displayed. This two-point setup creates a new threshold for a more consistent signal span.

Alignment Guidance

• Align Label to Arrow: Place the label web so it is centered on the arrow where the transducers are aligned.
• Align Gap to Line: Place the label gap in the center of the sensor using the alignment line. View from the top and use the output LED to center the label gap.
• Gentle Tension: Place label webbing so it slides along the bottom of the sensor gap plate for consistent setup and performance.

Output Indicators

• A Red LED illuminates when the sensor's output transistors are "ON".
• The Red LED flashes when a short circuit or overload is detected. If the output LED flashes on power up, a short circuit condition exists.

Button Functions

• AUTOSET/GAP Button:
  • 1. Push and Hold with gap in view for 2 seconds for AUTOSET.
  • 2. Tap for UP on Contrast Indicator, or reduce threshold.
  • 3. Change settings in MENU options.
• AUTOSET/LABEL Button:
  • 1. Push and Hold with label in view after GAP AUTOSET (useful for multi-layered labels).
  • 2. Tap DOWN on Contrast Indicator, or increase threshold.
  • 3. Change settings in MENU options.
• MENU Button:
  • 1. Scroll through MENU options.
  • 2. Hold during power up for additional Menu Options: Timer and Factory Diagnostics (Sensor Scope).

OLED Numerical Display

1. 1 to 10 bar Contrast Indicator.
2. Numerical display for threshold and feedback number.
3. Options Status Display: Button Lock or Unlock (?), auto adjust on/off (AUTO), output in Gap [gap-symbol] or on Label [label-symbol].
4. View Menu Options.

Note: Sensor is shipped with a protective plastic covering for the display. Remove for clearer viewing.

Detailed Setup (Using Menu Button)

Access advanced setup options by pressing the MENU button.

1. Initiate Dynamic Set

   Press ⬆️ or ⬇️ button to start a Dynamic Set. Pull labels and gaps through the sensor. Press ⬆️ or ⬇️ to complete. The sensor exits to run mode and should be ready for operation.

2. Auto Adjust

   Change from OFF to ON by momentarily pressing either the ⬆️ or ⬇️ button. The Auto Adjust evaluates signal levels and makes automatic adjustments to keep the sensor in optimum response levels.

3. Output Mode

   Change from GAP [gap-symbol] to LABEL [label-symbol] by momentarily pressing either the ⬆️ or ⬇️ button. The output will toggle back and forth in this mode.

4. Display Orientation

   Momentarily press either the ⬆️ or ⬇️ button to toggle orientation.

5. Timer Mode (Advanced Option)

   • Off Delay: Outputs stay on for a set time after the duration of input.
   • On Delay: Outputs turn on when the input exceeds the set time.
   • One Shot: Outputs turn on for a set time when triggered by input.
   • Debounce: Outputs are stabilized and held in the current state for the duration of the time setting.

6. Button Lockout

   Momentarily press either the ⬆️ or ⬇️ button to toggle from Lock ? to Unlock ?. Useful for tamper-free operation.

7. Quick Reference

   Press the ⬇️ button to scroll down through simple setup and options instructions. Press the ⬆️ button to scroll up.

8. Sensor Scope (Advanced Option)

   This option allows the operator to visually inspect the current setup for repeatability. The sensor scope will also reveal any nominal setup issues or sensitivities to label or gap thickness changes.
   • Momentarily press the ⬇️ button to shorten the time between signals.
   • Momentarily press the ⬆️ button to lengthen the time between signals.

How to Specify

1. Select Sensor: Ultrasonic Clear Label Sensor
2. Select Cable:
   • Blank = 6' (1.8m) Cable
   • C = Connector M12, 5-Pin (Standard)
3. Select Connector:
   • -1 = Standard M12 Connector (Includes both NPN and PNP)
   • -1M8 = M8, 4-Pin Connector (NPN/PNP Software Selectable)
   • -1M8LE = Wired like LER

Example: Ultrasonic Clear Label Sensor, Blank Cable, -1 Connector = CLS C -1
