WARNING . . .
Not To Be Used for
Personnel Protection
Never use these products as sensing
devices for personnel protection. Doing
so could lead to serious injury or death.
These sensors do NOT include the
self-checking redundant circuitry
necessary to allow their use in personnel
safety applications. A sensor failure
or malfunction can cause either an
energized or de-energized sensor output
condition. Consult your current Banner
Safety Products catalog for safety
products which meet OSHA, ANSI and
IEC standards for personnel protection.
!
CAUTION . . . This
sensor contains no user-
serviceable components.
Do not attempt to repair.
Incorrect component values
may produce hazardous laser radiation
levels.

Theory of Operation
A short electrical pulse drives a semiconductor laser diode to emit a pulse of light. The
emitted light is collimated through a lens, which produces a very narrow laser beam.
The laser beam bounces off the target, scattering some of its light through the sensor’s
receiving lens to a photodiode, which creates an electrical pulse. The time interval
between the two electrical pulses (transmitting and receiving the beam) is used to
calculate the distance to the target, using the speed of light as a constant.
Multiple pulses are evaluated by the sensor’s microprocessor, which calculates the
appropriate output value. The analog output provides a variable signal (4 to 20 mA or
0 to 10V dc, depending on model) that is proportional to the target’s position within
the user-programmed analog window limits. The discrete (switched) output energizes
whenever the target is located between the user-programmed discrete window limits.
Window limits for the analog and discrete outputs may be the same, or they may
be programmed independently.
Programming
The L-GAGE LT3 laser sensor has three selectable response speeds and can be
programmed in several ways for specific window limits.
Response Speed
Prior to setting window limits, use the sensor’s Speed push button to toggle
between the three response speed settings. The selected speed will be indicated
by one of the three Response Speed indicator LEDs (see Figure 2). See page 5 for
further information.
Sensor Power Up/Laser Enable
Allow 30 minutes after power-up to allow the sensor’s internal temperature to
stabilize, before operating or attempting to program the sensor. If the sensor will
be used in applications where the temperature is several degrees higher or lower
than ambient, allow the sensor to stabilize in that condition before programming the
window limits. (Range will decrease as the sensor warms up.)
The laser enable feature allows the sensor to be continually powered, and enabled
only when being used. This eliminates the need for the extended warm-up period
between uses. See page 6 for indicator status.
The sensor’s red Signal LED indicates the condition of the received signal from the
object being measured. When programming window limits, this LED must be ON solid
(not flashing) for the sensor to accept the setting. To ensure that the received signal will
not be marginal during operation, move the target object 300 mm beyond the furthest
desired setpoint during setup, and verify that the signal LED is still ON solid.

Window Limits
Window limits may be taught to the sensor in several ways, either using the push buttons
on the top of the sensor or via a remote switch.
Remote Programming
To program the sensor remotely or to disable the keypad, the Remote Programming
function may be used. Disabling the keypad prevents accidental or unauthorized
adjustment of the programming settings. Connect the yellow wire of the sensor to
+5 to 24V dc, with a remote programming switch connected between them.
NOTE: The impedance of the remote teach input is 55 kΩ.
Programming is accomplished by following the sequence of input pulses. The duration
of each pulse (corresponding to a push button “click”), and the period between multiple
pulses, are defined as “T”: 0.04 seconds ≤ T ≤ 0.8 seconds.
Analog Output Slope
The L-GAGE LT3 Sensor may be programmed for either a positive or a negative output
slope, based on which condition is taught first (see Figure 3). If the near limit is taught
first, the slope will be positive; if the far limit is taught first, the slope will be negative.
Banner’s unique scalable analog output (patent pending) automatically distributes the
output signal over the width of the programmed sensing window.
In the event of analog signal loss for longer than 2 seconds, the analog output goes to
0V dc or 3.6 mA, which may be used to trigger an alarm.
Teaching Analog Limits Using the Auto-Zero Feature (Analog Output)
For some analog applications, a sensing distance set point centered within a sensing
window may be required. The TEACH procedure is simple: teaching the same limit
twice causes the sensor to program a window centered on the position taught. This
window is 10 m wide (taught position ± 5 m).
Teaching Discrete Limits for Background Suppresson
For some applications, ignoring objects beyond a certain distance may be required. To
suppress the background, place a target object at the selected distance, and teach the
position twice. The sensor’s discrete output will activate when an object is detected
between the sensor’s minimum sensing distance and the taught position.
NOTE: The sensor allows for some forgiveness in this procedure. If the two limits are
not exactly the same (but less than 20 mm apart), the sensor will put the set
point at the “average” of the two limits.
