Controls
The Laser Sensor can detect small changes in reflective light due
to color or contrast changes, holes or slots in the surface or
reflectivity of the subject. The actual sensing distance varies, and
may be adjusted using the “Sensitivity” adjustment control on the
Laser Sensor. For maximum distance, it is advisable to use areas
of high contrast or reflective tape on the rotating object.
Operating the SPLS-5 as a triggering source
Mount the RLS-5P securely on a tripod or fixed surface that can be
moved for alignment purposes. For ease of alignment and reliability of
operation, locate the sensor as close to the target as practical (but not
within one inch). It is recommended that you aim the sensor at a
slight angle from perpendicular (approximately 15 degrees) to
ensure the sensor will detect only reflected pulses.
Turn the “Power” switch on the SPS-IM module to the ON position.
Open the shutter on the Laser Sensor. Observe that the LASER ON
LED illuminates.
CAUTION:
Avoid direct eye exposure to the laser beam.
Visually align the laser light with the target, ideally with the moving
equipment stopped. Start the equipment, and further adjust the manual
alignment and the “Sensitivity” control to maximize the brightness of
the green “TARGET” LED. This will be the condition of
optimum performance.
The pulse signal on the connector marked “Output” provides a sharp
leading edge for reliable and repeatable triggering of the connected
device. This output has a low impedance (50 ohms) and is capable of
