Q3X Contrast Laser Sensor

Quick Start Guide

This guide is intended to help you configure and install the Q3X Sensor. For detailed information on programming, performance, troubleshooting, sizing, and accessories, refer to the instruction manual at www.bannerengineering.com. To view the manual, look for product number 181485. Use of this document assumes prior knowledge of industry standards and practices.

WARNING: Not to be used for personal protection
Never use this device as a detection device for personal protection purposes. Doing so could result in serious injury or death. This device does not include the redundant self-monitoring circuits necessary to enable its use in personal safety applications. A malfunction or sensor failure may result in a live or dead sensor output condition.

Features

1. Output indicator (amber)

2. Screen

3. Buttons

 

Display and indicators

1. Stability indicator (STB = green)

2. Active TEACH indicators

DYN = Dynamic TEACH mode selected (amber)

WND = Symmetrical window thresholds are active (amber)

In Run mode, the 3-digit, 7-segment display provides real-time information on signal strength for all models and target position for models with a fixed background suppression distance. The numeric value from 0 to 990 represents the amount of light received divided by the threshold, and represents the excess gain of the detection event expressed as a percentage of the switching point. This value is called the normalized signal power (NSS). If the NSS value is 999, it indicates that the received light signal is saturated, so low-contrast detection is not possible.
In single-threshold teach modes (static two-point, dynamic, light level setting or dark level setting), the output switches to a value of 100 (with excess gain of 1.0).

For models with a specified background suppression distance, it indicates that an object is at a greater distance than the background suppression distance and is suppressed. In light mode operation, the output turns off when displayed. For LD50 models, the status of the sensor output when it is displayed can be controlled using the menu. By default, the sensor regards an object in the background as a dark signal and respects the LO/DO selection (light/dark mode operation).

In window configuration teach mode, the value 100 represents the learned signal strength. The displayed value is the percentage of received light divided by the learned signal strength. The output switches according to the displayed values above and below 100, as determined by the percentage window shift selected by the user.

Output indicator
– Ignition: conductive outputs (closed).
– Off: non-conductive outputs (open).

Stability indicator (STS)
– On: stable received light signal.
– Flashing: Light intensity is within the switching threshold hysteresis band.
– Off: No light signal is received.

Active TEACH indicators (DYN and WND)
– DYN and WND off: TEACH static two-point mode, light level setting or dark level setting selected (default is TEACH static two-point).
– DYN and/or WND flashing: Sensor is in TEACH mode.
– DYN on: Dynamic TEACH mode selected.
– WND on: Symmetrical window thresholds are active. The switching points are above and below 100 as determined by the percentage deviation.

Laser description and safety information

CAUTION: Adjusting controls or procedures other than those specified in this document may result in hazardous radiation exposure. Do not attempt to disassemble this sensor for repair. If a unit is defective it should be returned to the manufacturer.

Laser wavelength: 655 nm Output: < 0.42 mW Pulse duration: 5 µs

Installation

Placement of the safety label

Q3X sensors used in the United States must carry the safety label.

NOTE: Place the label in the position on the cord where you receive the least exposure to chemicals.

1. Remove the protective cover of the label adhesive.
2. Place the label around the cable of the Q3X as shown in the illustration.
3. Stick the two halves of the label together.

Sensor orientation

Proper orientation between the sensor and the object is important for correct detection. For reliable detection, orient the sensor as shown in relation to the detected object.
For models with background suppression, make sure that the target is within the contrast detection range and that the background objects are located outside the background suppression distance.

Mounting the sensor

1. Mount the sensor on a bracket.
2. Mount the sensor (or sensor and clamp) in the desired location on the machine or equipment. Do not tighten yet.
. 3. Check the alignment of the sensor.
4. Tighten the screws to secure the sensor (or sensor and clamp) in the aligned position.

Wiring diagram

2 = White
3 = Blue

5 = Grey

NOTE: Open connections must be connected to a terminal block.

The user can select the function of the input cable; for more information, see the User’s Manual. The input cable function is disabled by default.

Cleaning and maintenance

Proceed with care when installing and using the sensor. If the sensor lenses have fingerprints or are dirty with dust, water, oil, etc., scattered light may be emitted that can degrade the maximum performance of the sensor. Inject filtered compressed air onto the lens, then clean it with a cotton swab soaked in 70% isopropyl alcohol or water and a soft cloth.

 

Sensor programming

Program the sensor with the sensor buttons or the input cable (this system offers limited programming options, see the Instruction Manual for more information).
The input cable also serves to disable the buttons for safety reasons, preventing accidental or unauthorized modification of the programming. For more information, see the User’s Manual.

Setup Mode

Press and hold MODE for more than 2 seconds to enter Setup mode from Run mode.
2. Press the or buttons to scroll through the main menu.
Select the desired submenu by pressing and together.
4. To view the options contained in the submenu, press or .
5. Select an option from the submenu.
– To select and save a submenu option and return to the main menu, press and at the same time.
– To select and save a submenu item and return to Run Mode, press and together for more than 2 seconds.

Basic Learning Instructions

Follow these instructions to facilitate learning about the Q3X sensor. The instructions that appear on the sensor display vary depending on the type of TEACH mode selected. Two-point TEACH is the default mode.
Press and hold TEACH for more than 2 seconds to initiate the selected TEACH mode.
2. Present the object.
3. Press TEACH to learn the object. The object is learned and the sensor waits for the second object, if the selected TEACH mode requires it, or returns to Run mode.
Follow steps 4 and 5 only if requested by the sensor for the selected TEACH mode.
Present the second object.
5. Press TEACH to learn the object. The object is learned and the sensor returns to Run mode.
Refer to the instruction manual for more information and how other TEACH modes work.

Manual adjustments

Increase or decrease the gain manually by pressing – or + .
1. In Run Mode, press – or + once. The value of the signal strength flashes slowly.
2. Press – to decrease the sensor gain or + to increase the gain, – or + press and hold or to decrease or increase the gain quickly. After one second, the normalized signal strength flashes rapidly, the new setting is confirmed, and the sensor returns to Run mode.
Locking and unlocking sensor buttons
The lock and unlock function prevents unauthorised or unintentional changes to the programming.
To lock or unlock the sensor using the buttons, hold down and immediately press four times.
