Remote Teach Input 18 kΩ minimum (65 kΩ at 5V dc)
Remote TEACH To teach: Connect yellow wire to +5 to 24V dc
To disable: Connect yellow wire to 0 to +2V dc (or open connection)
See Remote Programming on pages 3 - 5.
Adjustments Response speed: Push button toggles between 3 response speeds
Window limits: TEACH-mode programming of near and far window limits (see programming procedure).
Limits may also be taught remotely via TEACH input (see page 4).

Factory defaults: 150 ms response speed
Window limits 0.3 m - 5 m using a 90% reflectivity white card
Push buttons enabled
Laser Control To enable laser beam: Connect red wire to +5 to 24V dc. See page 7 for delay times on enable.
To disable: Connect to 0 to +1.8V dc (or open connection)
Indicators Green Power ON LED: Indicates when power is ON, overloaded output and laser status
Yellow Output LED: Indicates when discrete load output is conducting
Red Signal LED: Indicates target is within sensing range and the condition of the received light signal
Yellow Speed LED: Indicates the response speed setting
Yellow TEACH LEDs: In programming mode, indicate active output(s)
NOTE: See page 7 for more information on indicator behavior.
