Red LED = Interface Lockout
Green LED = Power ON / Free light path
Red LED blinks = Standard label teach
Green LED blinks = Fine teach – translucent label teach
Red & Green LED blink = Short circuit mode or label too
translucent or web too opaque
Teaching Sensor and Setup
Initial setup includes mounting the sensor securely and then
providing power through a 4-pin pico cordset. The initial
factory settings have the threshold on the sensor preset so
that most opaque labels may be sensed on a translucent web.
Teaching Most Opaque Labels (on translucent web):
To teach the sensor insert the material to be sensed into the
fork so that it enters the beam path.
Position the material so that the translucent web is in the
beam path in the fork.
Press and release the teach button once. The red LED on the
user interface will begin to blink.
While the red LED is blinking quickly insert and remove the
opaque label into and out of the sensors beam path until the
red LED stops blinking.
Test your setup by ensuring the green LED on the user
interface blinks when the label is inserted and removed.
To lock out user interface hold down teach button for six
seconds until red LED blinks once.
Release button and notice that both red and green LEDs are
illuminated on the user interface.
To unlock user interface hold down teach button for six
seconds until red LED turns off.
Release button and notice that only green LED is illuminated.
For remote teach follow the instructions in the wiring section
using a momentary pushbutton switch.
Teaching Translucent Labels:
To teach the sensor insert the material to be sensed into the
fork so that it enters the beam path.
Position the material so that the translucent web is in the
beam path in the fork.
Press and release the teach button twice. The green LED on
the user interface will begin to blink.
While the green LED is blinking quickly insert and remove the
translucent label into and out of the sensors beam path until
the green LED stops blinking.
Test your setup by ensuring the green LED on the user
interface blinks when the label is inserted and removed.
To lock out user interface hold down teach button for six
seconds until red LED blinks once.
Release button and notice that both red and green LEDs are
illuminated on the user interface.
To unlock user interface hold down teach button for six
seconds until red LED turns off.
Release button and notice that only green LED is illuminated.
For remote teach follow the instructions in the wiring section
using a momentary pushbutton switch.
Important: For Label detection use Dark operate.
For Web detection use Light operate.
