QS30 Laser Overview
The QS30 is an easy-to-use, high-performance laser sensor whose many
configuration options make it suitable for demanding applications. It provides
high-performance sensing in low-contrast applications at relatively long range. It
features static, dynamic and single-point TEACH-mode programming, in addition
to manual fine adjustment, remote programming and security lockout options. A
SETUP mode also may be used to change the sensor’s output response
(see page 8).
The sensor features two identically configured outputs, one each NPN and PNP.
The sensor’s compact housing has a large, easy-to-see bar graph display plus
bright LEDs for easy programming and status monitoring during operation. The
sensor can be side-mounted, using its integral mounting holes, or front-
mounted, via its 30 mm threaded barrel. Figure 1. QS30 features

Class 2 Laser Safety Notes:
Low-power lasers are, by definition, incapable of causing eye injury within the
duration of the blink (aversion response) of 0.25 seconds. They also must emit only
visible wavelengths (400 - 700 nm). Therefore, an ocular hazard can exist only if an
individual overcomes their natural aversion to bright light and stares directly into the
laser beam.
For safe laser use:
• Do not permit a person to stare at the laser from within the beam.
• Do not point the laser at a person’s eye at close range.
• Terminate the beam emitted by a Class 2 laser product at the end of its useful path.
Locate open laser beam paths either above or below eye level, where practical.
CAUTION
Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure; per
EN 60825. Do NOT attempt to disassemble this sensor for repair. A
defective unit must be returned to the manufacturer.

Class 1
Lasers that are safe under reasonably foreseeable
conditions of operation, including the use of optical
instruments for intrabeam viewing.

Class 2
Lasers that emit visible radiation in the wavelength
range from 400 nm to 700 nm where eye
protection is normally afforded by aversion

Sensor Programming
Sensor configuration is accomplished through TEACH-mode programming and
SETUP mode. After TEACH 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 (see page 7). Two push buttons,
Dynamic (+) and Static (-), or the remote wire, may be used to access and set
programming parameters.
Sensor programming may be accomplished using any of three TEACH methods. A
single switching threshold may be programmed using either dynamic (on-the-fly) or
static TEACH. In addition, Single-Point Static TEACH may be used to define a sensing
window, centered on a single taught condition. Single-Point TEACH programming
may be accomplished only statically.
Remote Programming
The Remote Programming function may be used to program the sensor 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
Returning to RUN Mode
TEACH and SETUP modes each may be exited either after the 60-second time-out, or
by exiting (cancelling out of) the process:
• In Static TEACH mode, press and hold the Static (-) button (or hold the remote line)
for 2 seconds to exit. The sensor returns to RUN mode without saving any new
settings.
• In SETUP mode, press and hold both the Static (-) and Dynamic (+) buttons (or hold
the remote line) for 2 seconds to exit. The sensor returns to RUN mode and saves
the current setting.

Two-Point Static TEACH
• Two-point TEACH
• Sets a single switching threshold
• Threshold is adjustable using “+” and “-” buttons (Manual Adjust)
Two-Point Static TEACH is the traditional setup method, used when two conditions
can be presented by the user. The sensor locates a single sensing threshold (the
switch point) midway between the two taught conditions, with the Output ON
condition on one side, and the Output OFF condition on the other (see Figure 2).
The first condition taught is the ON condition.The Output ON and OFF conditions can
be reversed by changing Light/Dark Operate status in SETUP mode.
Two-Point TEACH and Manual Adjust
Using Manual Adjust with Two-Point TEACH moves the switching threshold. The
lighted LED on the light bar will move to exhibit the relative amount of received signal.

Dynamic TEACH and Adaptive Thresholds
• Teach on-the-fly
• Sets a single switching threshold
• Threshold position is adjustable using “+” and “-” buttons (Manual Adjust)
Dynamic TEACH is best used when a machine or process may not be stopped for
teaching. A variation of two-point TEACH, it programs the sensor during actual
machine run conditions, taking multiple samples of the light and dark conditions and
automatically setting the threshold at the optimum level (see Figure 3).
Dynamic TEACH activates the sensor’s adaptive threshold system, which continuously
tracks minimum and maximum signal levels, and automatically maintains centering of
the switch point between the light and dark conditions. The adaptive threshold system
remains in effect during RUN mode. The adaptive routine saves to non-volatile
memory at least once per hour.
When Dynamic TEACH mode is used, the Output ON state (light or dark operate) will
remain as it was last programmed. To change the Output ON state, use SETUP mode
(see page 8).
The sensing set point may be adjusted (fine-tuned) whenever the sensor is in RUN
mode by clicking the “+” and “-” buttons. However, when a manual adjustment is
made, the adaptive threshold system is disabled (cancelled).

Single-Point Static TEACH (Sensing Window)
• Sets a single ON condition

• Sensing window size (sensitivity) is adjustable using “+” and “-” buttons
(Manual Adjust)
Single-Point TEACH is most useful when a product may not always appear in the
same place, or when other signals may appear. Single-Point TEACH programs a
sensing window, with the Output ON condition inside the window, and the Output OFF
conditions outside the window (see Figure 4). Output ON and OFF conditions can be
reversed by changing Light/Dark Operate status in SETUP mode.
Single-Point TEACH programming may be accomplished only using Static TEACH.
The sensor learns a single sensing condition, and adds switching thresholds above
and below the taught condition to create a sensing window.
Single-Point TEACH and Manual Adjust
Using Manual Adjust with Single-Point TEACH expands or contracts the size of the
window. The lighted LEDs on the light bar separate to a greater or lesser extent to
exhibit the relative sensing window size.

SETUP Mode
SETUP mode is used to change sensor output response for:
• Light or Dark operate
• 30-millisecond pulse stretcher (OFF delay), if required.
The status LEDs, active only during SETUP mode, indicate the output response
configuration when the sensor will be in RUN mode. Four combinations are possible:
Light Operate, No Delay
Dark Operate, No Delay
Dark Operate, 30 ms Delay
Light Operate, 30 ms Delay
To access SETUP mode and change the output response settings:
1) Press and hold BOTH push buttons (or double-pulse Remote line) until the
green LED indicator turns OFF.
2) Click EITHER push button (or pulse Remote line) to toggle through the four
possible setting combinations.
3) Press and hold both push buttons (or hold Remote line) until the green LED
indicator turns ON, indicating return to RUN mode.
NOTES: • If SETUP mode programming is interrupted and remains inactive for 60
seconds, the sensor returns to RUN mode with the most recent settings
(i.e., exits and saves current selection).
• SETUP mode operates in the “background”, while the outputs are active.
Manual Adjust
Use during RUN mode, accomplished via push buttons only.
Two-Point TEACH (Static or Dynamic):
• Fine-tunes sensing threshold set-point value
• Press “+” to increase; press “-” to decrease
Single-Point TEACH:
• Adjusts sensing window size (tolerance) for the single-point target
condition
• Press “+” to increase; press “-” to decrease
The lighted bargraph LEDs move to reflect the increase or decrease.
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
page 4, and four-pulse to either enable or disable the push buttons:
