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
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
more information.

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 accord-
ing 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
