Using the L-GAGE Q50A Analog Output Sensor
Response Speed
To control the response speed, connect the black wire as
follows:
Fast Speed (4 ms): Connect black wire to +5 to 30V dc
Slow 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 push
button.
The Q50A sensor operates in two modes: TEACH (or
programming) mode and RUN mode.
NOTE: All LED indicators momentarily go OFF when the sensor
changes state between RUN and TEACH modes.
Indicator Status Conditions
Indicator Status
Range 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 limits
LED OFF — Target is outside taught window limits
(yellow/red) Red — Sensor is in TEACH mode
TEACH-Mode Programming
Push-Button Procedure
1. Press the Teach push button until the Teach LED turns red
(hold button in for about 2 seconds). This indicates the
sensor is waiting for the first window 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 teach the sensor the first limit. The Teach
LED will flash red at 2 Hz 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 Teach
push button again to teach the sensor the second limit. The
Teach LED will return to either yellow or OFF as the sensor
returns to RUN mode.
