Overview

QS30LLP and QS30LLPC Series sensors are easy-to-use, high-performance laser sensors whose many configuration options make them suitable for demanding applications. Each sensor features two identically configured outputs, one each NPN and PNP.

The compact housing has a large, easy-to-see bargraph display plus bright LEDs for easy configuration and status monitoring during operation. The sensor can be side-mounted, using integral mounting holes, or front-mounted, via the 30 mm threaded barrel.

MODEL QS30LLP(Q) is configured using the Maximum Excess Gain SET procedure. It is useful for long-range applications and high variations in contrast, such as beam-break applications where the target objects are larger than the beam. See Maximum Excess Gain

SET - Model QS30LLP on page 3 for more information.

MODEL QS30LLPC(Q) is configured using the Low-Contrast SET procedure. It is useful for small object detection and other applications with small variations in contrast, such as yarn- or thread-break applications. See Low-Contrast SET - Model QS30LLPC on page 5 for more information.

Figure 1. Model QS30LLP Features

Sensor Configuration

Sensor configuration is accomplished using the SET and SETUP modes. After SET mode has defined the sensing parameters, SETUP mode may be used to add an OFF-delay or change the light/dark operate status. Manual Adjust may be used to fine-tune the thresholds. Two push buttons, “+” and “-”, may be used to access and set sensing parameters. In addition, the remote wire also may be used for

some procedures (see below).

Remote Configuration

The Remote Configuration function may be used to set the sensor threshold remotely or to disable the push buttons for security. Connect the gray wire of the sensor to ground (0V dc), with a remote programming switch connected between them. Pulse the remote line according to the diagrams in the programming procedures. The length of the individual programming pulses is equal to the value T:

0.04 seconds ≤ T ≤ 0.8 seconds

Push Button Disable

In addition to its programming function, Remote Programming may be used to disable the push buttons for security. Disabling the push buttons prevents undesired tampering with the programming settings. Connect the gray wire of the sensor as described on above, and four-pulse to either enable or disable the push buttons:

Maximum Excess Gain SET - Model QS30LLP

• Sets the sensor for maximum excess gain without allowing false proxing. Provides maximum contrast between any reflector and a blocked condition and is stable even in dirty environments.

• Useful for long-range applications and high variations in contrast, such as beam-break applications where the target objects are larger than the beam.

Sensor can be aimed at an object or the reflector during SET process to obtain the same result. All conditions darker than the switchpoint condition result in ON output (Dark Operate). Output ON and OFF conditions can be reversed by changing Light/Dark Operate in SETUP mode (factory setting: Dark Operate).

Figure 3. Maximum Excess Gain SET (Dark Oper-

ate shown)

Manual Adjust – Maximum Excess Gain SET

During RUN mode, adjusts switchpoint up or down via “+” or “–” push buttons.

• Each push button “click” adjusts the switchpoint up by approximately 0.5X excess gain or down by the same increments.

• The lighted bargraph LEDs move to reflect the increase or decrease of excess gain relative to the switchpoint.

• LEDs #7 and 8 flash when maximum gain is achieved; LEDs #1 and 2 flash when minimum gain is achieved.

When the received signal is at any level greater than 6X excess gain, the first “–” (minus) click to reduce excess gain reduces it to the 6X level. Subsequent “–” clicks result in decreased values as shown in Specifications on page 8 (approximately 2 clicks per LED change). To return to maximum excess gain, either press “+” repeatedly until LEDs #7 and 8 flash, or hold the “+” button for longer than 2 seconds. For example, in an application that results in 20X excess gain, pressing “–” once lowers the gain to 6X, exhibited by LED #8 ON. Pressing it twice more results in approximately 5X excess gain, exhibited by LED #7 ON. Holding the “+” button for 2 seconds results in a return to maximum gain (20X), exhibited by LEDs #7 and 8 flashing.

Low-Contrast SET - Model QS30LLPC

• Sets a switchpoint at 35 percent below the signal from the retroreflector.

• Useful for small object detection and other applications with small variations in contrast, such as yarn- or thread-break applications.

• Sensor must be aimed at the reflector during the SET process. All conditions darker than the switchpoint condition result in ON output (Dark Operate). Output ON and OFF conditions can be reversed by changing Light/ Dark Operate in SETUP mode (factory setting: Dark Operate).

Manual Adjust – Low-Contrast SET

During RUN mode, adjusts switchpoint up or down via “+” or “–” push buttons.

SETUP mode is accomplished via the sensor’s two push buttons. It is used to change sensor output response for:

• Light or Dark Operate

• 30-millisecond pulse stretcher (OFF-delay), if required.

WORLD-BEAM QS30 LLP and LLPC

Installation Notes

Conventional retroreflective photoelectric sensors are extremely easy to align. Beam angles are wide, and retro targets are forgiving to the light beam’s angle of incidence. The beam of this laser sensor is very narrow, compared with the beam of most retro sensors. As Figure 6 indicates, the effect of angular misalignment can be dramatic. Alignment is critical because the beam may miss the retroreflective target unless the target is large.

Sensor-to-Target Distance (X)

Beam Displacement (Y) for 1º of Misalignment

1.5 m (5 ft) 25 mm (1 in)

3 m (10 ft) 50 mm (2 in)

6 m (20 ft) 100 mm (4 in)

15 m (50 ft) 250 mm (10 in)

Figure 6. Beam Displacement per degree of misalignment

30 m (100 ft) 500 mm (20 in)

For example, with one BRT-51X51BM mounted at a distance of 6 m (20 ft) from the sensor, one degree of angular misalignment will cause the center of the laser beam to miss the center of the target by 100 mm (4 in).

Alignment Tip

When using a small retroreflective target at medium or long range, it is often useful to temporarily attach (or suspend) a strip of retroreflective tape (e.g., BRT-TVHG-2X2) along a line that intersects the actual target. The visible red laser beam is easily seen in normal room lighting on such tape. Sight along the beam toward the target (from behind the sensor). Move the sensor to scan the laser beam back and forth across the retro tape strip. Use the tape strip to guide the beam onto the target.

Consider using sensor mounting bracket model SMB30SC (see Accessory Brackets on page 11). This swivel bracket can simplify multiple-axis alignment. Alignment is complete when the visible image is centered on the retro target. The perpendicularity of the laser beam to the face of the retro target is forgiving, just as it is with a conventional retroreflective sensor.

Effective Beam Size

Unlike conventional retroreflective sensors, the retroreflective laser has the ability to sense relatively small profiles. Figure 7 indicates the diameter of the smallest opaque rod which will reliably break the laser beam at several sensor-to-object distances using sensor model QS30LLP(Q). These minimum object sizes were measured with the sensor aligned to a BRT-51X51BM reflector and the gain set to maximum using the Max Excess Gain SET. This sensor is typically recommended for long-range applications of relatively small targets that will completely break the beam.

Figure 7. Minimum object detection size vs.

distance from sensor, model QS30LLP(Q)

Smaller objects can be detected by using model QS30LLPC(Q), adjusting the sensor gain down using the Manual Adjust, or performing a Low-Contrast SET of the reflector. Objects as small as 2.0 mm can be reliably detected after per-

Sensor-to-Object Distance (X)

Minimum Object Detection Size

forming the Low-Contrast SET at ranges up to 6 m (18 ft). This sensor is typically recommended for shorter-range applications detecting very small targets that may break only a portion of the beam.

0.3 m (1 ft) 2.5 mm (0.10 in)

1.5 m (5 ft) 5.0 mm (0.20 in)

Note that the shape of the beam is elliptical. The minimum object sizes listed assume passage of the rod across the major diameter of the ellipse (worst case). It may be possible to detect objects smaller than the sizes listed if the

direction in which the objects pass through the beam can be controlled.

18 m (59 ft) 13 mm (0.52 in)

Retroreflector Recommendations

• BRT-51X51BM recommended for beam-block applications up to 18 m range.

• BRT-TVHG-2X2 recommended for applications up to 2 m range. (This retroreflector is an adhesive-backed sealed tape with micro-
