L-GAGE Q50 – Analog Output Sensor

L-GAGE Q50 Analog Output Sensor Overview

The Q50 is an easy-to-use triangulation sensor which provides asophisticated, yet cost-effective solution for demandingmeasurement applications. Q50 Series sensors feature compact,all-in-one design and require no separate controller.

Near and far sensing window limits are set quickly using simplepush-button or remote signal TEACH-mode programming. Theanalog output has the option of being set with a sensingdistance centered within a 100 mm window. The sensor featuresBanner’s patented digital signal processing algorithm (U.S. patent#6,122,039), which automatically distributes the 0 to 10V dc (or 4to 20 mA) output signal over the width of the programmedwindow.

Optical TriangulationThe function of the Q50 Sensor is based on optical triangulation(see Figure 1). The emitter circuitry and optics create a lightsource which is directed toward a target. The light sourcebounces off the target, scattering some of its light through thesensor’s receiver lens to its position-sensitive-device (PSD)receiver element. The target’s distance from the receiverdetermines the light’s angle to the receiver element; this angledetermines where the returned light will touch the PSD receiverelement.

The position of the light on the PSD receiver element isprocessed through analog and digital electronics and analyzedby the microprocessor, which calculates the appropriate outputvalue. The analog output provides either a current or voltageoutput proportional to the target’s position within the user-programmed analog window limits (see page 4).

Using the L-GAGE Q50 Analog Output Sensor

Response Speed

To control the response speed, connect the black wire asfollows:

Fast Speed (4 ms): Connect black wire to +5 to 30V dcSlow Speed (64 ms): Connect black wire to 0 to +2V dc (or

open connection)

Window Limits

Window limits may be taught to the sensor either remotely(using the gray wire) or by using the sensor’s Teach pushbutton.

The Q50 sensor operates in two modes: TEACH (orprogramming) mode and RUN mode.

NOTE: All LED indicators momentarily go OFF when the sensorchanges state between RUN and TEACH modes.

Indicator Status Conditions

Indicator StatusRange LED Green — Target is within sensing range(green/red) Red — Target is outside sensing range

OFF — Sensor Power OFF

Teach/Output Yellow — Target is within taught window limitsLED OFF — Target is outside taught window limits (yellow/red) Red — Sensor is in TEACH mode

TEACH-Mode Programming

Push-Button Procedure1. Press the Teach push button until the Teach LED turns red

(hold button in for about 2 seconds). This indicates thesensor is waiting for the first window limit.

2. Position the target for the first limit. The Range LED should begreen, indicating a valid target. Briefly “click” the Teach pushbutton. This will teach the sensor the first limit. The TeachLED will flash red at 2 Hz to acknowledge receiving the firstwindow limit; it is now waiting for the second limit.

3. Position the target for the second limit and “click” the Teachpush button again to teach the sensor the second limit. TheTeach LED will return to either yellow or OFF as the sensorreturns to RUN mode.

Teaching Analog Limits Using a Fixed 100 mm WindowFor some analog applications, a sensing distance set point centered within a sensingwindow is required. The TEACH procedure is simple: teaching the same limit twicecauses the sensor to program a window centered on the position taught. This windowis 100 mm wide (taught position ±50 mm).

Remote ProgrammingA function is provided to program the sensor remotely or to disable/enable the pushbutton; this is accomplished via the gray wire. Disabling the push button preventsanyone on the production floor from adjusting any of the programming settings.Connect the gray wire of the Q50 Gauging Sensor to +5 to 30V dc, with a remoteprogramming switch connected between them. NOTE: The impedance of the remoteteach input is 15 kΩ

To program, pulse the wire as illustrated in Figure 5. NOTE: The duration of each pulse(corresponding to a push button “click”) is 0.04 to 0.8 seconds.

RUN and TEACH modes.

Range LED When the sensor detects a target within its sensing range (either 100 to 300 mm forvisible-beam models, or 100 to 400 mm for infrared beam models) the LED will besolid green. In the absence of a target, the Range LED is solid red. Refer to theIndicator Status table on page 3.

Teach/Output LEDIn RUN mode, the Output LED is yellow when a target is sensed within theprogrammed window limits; otherwise the Output LED is red. Refer to the IndicatorStatus table on page 3.

Analog OutputThe Q50 gauging sensor may be programmed for either a positive or a negative outputslope (see Figure 6). If the near limit is taught first, the slope will be positive; if the far limitis taught first, the slope will be negative. Banner’s patented scalable analog outputautomatically distributes the output signal over the width of the programmed sensingwindow. (Output is either 0 to 10V or 4 to 20 mA, depending on model.)

Teaching Analog Limits Using a Fixed 50 mm WindowFor some analog applications, a fixed sensing window centered about a taught point isrequired. The TEACH procedure is simple: teaching the same limit twice causes thesensor to program a window centered on the position taught. This window is 50 mmwide (taught position ± 25 mm).

Remote ProgrammingA function is provided to program the sensor remotely or to disable/enable the pushbutton; this is accomplished via the gray wire.

L-GAGE Q50 – Complementary Discrete Output Sensor

Sensor Overview

The Q50 Complementary Discrete is an easy-to-use triangulationsensor which provides a sophisticated, yet cost-effectivesolution for demanding applications. Q50 Series sensors featurecompact, all-in-one design and require no separate controller.

Each sensor has two discrete outputs (both NPN or both PNP).The complementary output can be configured for one of twoconditions:

• A sensing window consisting of two switch points• A single switch point, as with an adjustable-field sensor

Optical TriangulationThe function of the Q50 Sensor is based on optical triangulation(see Figure 1). The emitter circuitry and optics create a lightsource which is directed toward a target. The light sourcebounces off the target, scattering some of its light through thesensor’s receiver lens to its position-sensitive-device (PSD)receiver element. The target’s distance from the receiverdetermines the light’s angle to the receiver element; this angledetermines where the returned light will touch the PSD receiverelement.

The position of the light on the PSD receiver element isprocessed through digital electronics and analyzed by themicroprocessor. The microprocessor will compare the targetposition to the taught window limits and then change thediscrete outputs as required.

Using the L-GAGE Q50 Complementary Discrete Output Sensor

Response SpeedResponse speed is either Fast (4 ms) or Slow (48 ms), depending on model.

Window LimitsWindow limits may be taught to the sensor either remotely (using the graywire) or by using the sensor’s Teach push button.

The Q50 sensor operates in two modes: TEACH (or programming) mode andRUN mode.

NOTE: All LED indicators momentarily go OFF when the sensor changes statebetween RUN and TEACH modes.

Indicator Status ConditionsIndicator StatusRange LED Green — Target is within sensing range(green/red) Red — Target is outside sensing range

Flashing Green — Discrete output overloadedOFF — Sensor Power OFF

Teach/Output Yellow (window limits) — Target is within taught limitsLED Yellow (fixed field) — Target is closer than cutoff limit(yellow/red) OFF — Target is outside taught window limits

Red — Sensor is in TEACH mode


Push-Button Procedure for Teaching Window Limits (ComplementaryOutputs)1. Press and hold the Teach push button until the Teach LED turns red (depress

button for about 2 seconds). This indicates the sensor is waiting for the firstwindow limit.

2. Position the target for the first limit. The Range LED should be green,indicating a valid target. Briefly “click” the Teach push button. This will teachthe sensor the first limit. The Teach LED will flash red at 2 Hz toacknowledge receiving the first window limit; it is now waiting for the secondlimit.

3. Position the target for the second limit and “click” the Teach push buttonagain to teach the sensor the second limit. The Teach LED will return toeither yellow or OFF as the sensor returns to RUN mode.

NOTE: The yellow LED follows the black wire output.

Push-Button Procedure for Teaching a Single Sensing Set Point(Complementary Outputs – Adjustable-Field Style)The black wire conducts when the target is inside the programmed set point. The whitewire conducts when the target is outside (away from) the set point (see Figure 7).

1. Press and hold the Teach push button until the Teach LED turns Red (depress buttonfor approximately 2 seconds).

2. Position the target at the sensing set point. The Range LED should be green,indicating a valid target. Briefly “click” the Teach push button. This will teach thesensor the first limit. The Teach LED will flash red at 2 Hz to acknowledge receivingthe first window limit; it is now waiting for a second limit.

3. Maintain the same target position and “click” the Teach push button again to teachthe same window position. The Teach LED will return to either yellow or OFF as thesensor returns to RUN mode.

Note: The yellow LED will follow the black wire output.

Remote ProgrammingA function is provided to program the sensor remotely or to disable/enable the pushbutton; this is accomplished via the gray wire. Disabling the push button preventsanyone on the production floor from adjusting any of the programming settings.Connect the gray wire of the Q50 Sensor to +5 to 30V dc, with a remote programmingswitch connected between them. NOTE: The impedance of the remote teach input is 15kΩ.

To program, pulse the wire as illustrated inFigure 6. NOTE: The duration of each pulse(corresponding to a push button “click”) is0.04 to 0.8 seconds.

Run ModeNOTE: All LED indicators momentarily go

OFF when the sensor changes statebetween RUN and TEACH modes.

Range LED When the sensor detects a target within itssensing range (either 100 to 300 mm forvisible-beam models, or 100 to 400 mmfor infrared beam models) the LED will besolid green. In the absence of a target, theRange LED is solid red. Refer to theIndicator Status table on page 3.

Teach/Output LEDIn RUN mode, the Output LED is yellowwhen a target is sensed within theprogrammed window limits; otherwise theOutput LED is red. Refer to the IndicatorStatus table on page 3.

Complementary Discrete OutputsThe complementary discrete outputs areeither both NPN or both PNP. The outputsare configured via the Teach procedure toeither a single window or a fixed-field(single set point) application. The outputsare short circuit-protected and can switchup to 150 mA (resistive load).
