Power Up/Laser Enable Indicators
When powering up the sensor, the following should occur:
• All LEDs turn ON for 1 second
• Allow 0.6 second delay for Laser Enable at power up. If sensor is already powered up,
see table at left for Laser Enable time. Laser Disable time for all speeds is
50 ms.
Signal LED
(red) – indicates the strength and condition of the sensor’s incoming signal.
Output LED
(yellow) – lights when a target is sensed within the programmed discrete
window limits.
Power ON/OFF LED
(green) – indicates the operating status of the sensor.
