L-GAGE Laser Gauging Sensor Overview

Banner’s Class 2 visible laser displacement sensor brings a sophisticated, yet cost­effective solution to precision measurement applications. L-GAGE Series sensors
feature all-in-one design and require no separate controller.

Near and far sensing window limits are set quickly using simple push-button or
remote signal TEACH-mode programming. One sensor can simultaneously provide
both analog and discrete (switched) outputs. Sensing window limits for each output
may be independently programmed, if desired. The analog signal features Banner’s
unique scalable output (patent pending), which automatically distributes the 4 to 20
milliamp output signal over the width of the programmed sensing window. If an
analog voltage output is required, this can be accomplished by using an alternate
hookup. (See Hookups, page 5.)

The L-GAGE Laser Gauging Sensor boasts many additional features, including
selectable response speed, self-diagnostics with alarm output, comprehensive status
indicator system, and unique output “hold” function for momentary signal loss in
profiling applications.

Optical Triangulation

The design of the L-GAGE Laser Gauging Sensor is based on optical triangulation (see
figure 1). An emitter transmits visible laser light through a lens, toward a target. The
laser light beam from the emitter bounces off the target, scattering some of its light
through another lens to the sensor’s PSD (position-sensitive device) receiver element.
The target’s distance from the receiver determines the angle the light travels to the
receiver element; this angle in turn determines where the received light will fall along
the PSD receiver element.

The position of the light on the PSD receiver element is processed through analog
and digital electronics and analyzed by the microprocessor,
which calculates the appropriate output value. The analog
output provides a variable 4 to 20 milliamp current that is
proportional to the target’s position within the user-programmed
analog window limits (see page 8). The discrete (switched)
output energizes whenever the target is located between the
user-programmed discrete window limits. Analog and discrete
window limits may be the same, or programmed independently.

*NOTE: The bare shield wire should be connected as follows:

1) If the sensor housing is mounted so that it is in continuity with both the machine
frame and earth ground, connect the bare wire (also) to earth ground.

2) If the sensor housing is mounted so that it is insulated from the machine frame,
connect the bare wire to -V dc (together with the blue wire).

3) If the sensor is mounted so that it is in continuity with the machine frame, but
not with earth ground, do not connect the bare wire (i.e. cut off the bare wire).

**NOTE:

For best results, install a small
amount of capacitance (e.g., 0.1µF)
in parallel with the load resistor

Window Limits

Window limits may be taught to the sensor in several ways. The following methods
describe the TEACH procedures for programming using the sensor push buttons;
remote programming (remote TEACH) procedures are described on page 7.

Teaching Limits for Either Analog or Discrete Output

1. Choose the output for the first set of window limits (analog or discrete) and push
and hold the corresponding button until the tri-color TEACH LED turns ON
(solid). This indicates the sensor is waiting for the first limit: red for analog
output, or green for discrete output.

2. Position the target for the first limit and briefly “click” the same button. This will
teach the sensor the first limit. The TEACH LED will flash at 2Hz to acknowledge
receiving the first window limit; it is now waiting for the second limit.

3. Position the target for the second limit and “click” the button again. This will
teach the sensor the second limit. The TEACH LED will turn OFF to indicate that
the sensor will now function in normal RUN mode.

4. Repeat for the opposite output (analog or discrete) if a second output is desired.

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 10 mm wide window centered on the position
taught (position ±5 mm).

Teaching Fixed-Field Sensing Mode (Discrete Output)

Teaching the same limit twice creates a sensing window with the far limit at the teach
distance and the near limit at the minimum operating range of the sensor
(approximately 44 mm).

Teaching Limits for Both Analog and Discrete Outputs Simultaneously

If you want both your discrete and analog outputs to be set at exactly the same limits,
you may set both simultaneously.

1. Push and hold either the Analog or the Discrete programming push button until
the tri-color TEACH LED turns ON. “Click” the other button (Analog or Discrete).
The TEACH LED turns Yellow. The sensor is waiting for the first limit.

2. Position the target for the first limit and “click” either TEACH button. The TEACH
LED will flash at 2Hz, alternating red and green, to acknowledge receiving the
first window limit; it is now waiting for the second limit.

3. Position the target for the second limit and “click” the buttons again to teach the
sensor the second limit. The TEACH LED will turn OFF to indicate that the sensor
will now function in normal RUN mode.

Remote Programming

To program the sensor remotely or to disable the keypad, the Remote Programming
function may be used. Disabling the keypad prevents anyone on the production floor
from adjusting any of the programming settings. Connect the yellow wire of the
L-GAGE Laser Gauging Sensor to +5 to 30V dc, with a remote programming switch
connected between them. NOTE: The impedance of the remote teach imput is 55 kΩ.

Programming is accomplished by following the sequence of input pulses, following
the button-pushes and “clicks” for programming on the sensor buttons. The duration
of each pulse (corresponding to a push button “click”), and the period between
multiple pulses, are defined as: 0.04 seconds < T < 0.8 seconds.

To access each of the programming modes, pulse the remote switch a prescribed
number of times:

• 1 pulse: Discrete TEACH Mode

• 2 pulses: Analog TEACH Mode

• 3 pulses: Dual Discrete/Analog TEACH Mode

• 4 pulses: Disables (locks out) or enables the keypad for security

RUN Mode

Signal LED

The Signal LED indicates the strength and condition of the sensor’s incoming signal.

Signal LED Status Indicates

OFF

No signal is received, or the target is beyond the range limitations
of the sensor (with some tolerance beyond the recommended
minimum and maximum sensing distance)

Flashing @ 2Hz Received signal is adequate for processing

Flashing @ 10Hz

Received signal is in saturation (i.e., signal is too strong); alarm
output energizes

ON Solid Received signal is within the nominal conditions for the sensor

Output LED

The Output LED lights when the discrete output is conducting.

Power ON/OFF LED

The Power ON/OFF LED indicates the operating status of the sensor.

Power ON/OFF LED Indicates

OFF Power is OFF
Flashing @ 2Hz Discrete or alarm output is overloaded
Flashing @ 1Hz Power ON, Laser is disabled
ON Solid Sensor is operating normally (power is ON, Laser enabled)

Power Up/Laser Enable

When powering up the sensor, the following should occur:

• All LEDs turn ON for 1 second

• Allow 1.25 second delay for Laser Enable at power up. (If sensor is already powered

up, allow 0.25 second for Laser Enable.)

Analog Output

The L-GAGE Laser Gauge may be programmed for either a positive or a negative output
slope, depending on which condition is taught first (see Figure 5). 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. Factory
analog output is 4 to 20 mA; if a voltage output (e.g. 1 to 5V dc) is required, this can be
accomplished by using an alternate hookup (see Hookups, page 5).

The L-GAGE also features a 2-second hold upon loss of the analog signal, which is useful
for profiling and similar applications. In the event of analog signal loss for longer than 2
seconds, the analog output goes to 3.6 mA, which may be used to trigger an alarm.

Class 2 Safety Notes

Low-power lasers are by definition
incapable of causing eye injury within
the duration of the blink, or aversion
response of 0.25 seconds. They must
also emit only visible wavelengths
(400-700 nm). Therefore, an ocular
hazard can only exist if an individual
overcomes their natural aversion to
bright light and stares directly into the
laser beam. The product requirements
for these lasers are to have a [hazard]
label and to have an indicator light to
indicate laser emission.

The two operational safety rules are:

• 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

Beam Paths:

The beam emitted by a class 2 laser
product should be terminated at the
end of its useful path. Open laser beam
paths should be located above or
below eye level where practical.

Recommended

NOT Recommended

CAUTION . . .

This sensor contains no user-servicable components. Do not attempt to
repair. Incorrect component values may produce hazardous laser
radiation levels.
