Run Mode

Normal operation of the SLE10 Expert is called RUN mode. The two LED indicators (bi-color green/red and amber) operate as follows in RUN Mode:

Green (RUN Mode)

ON steady whenever power is applied

Flashes as received light level approaches the switching threshold (stability indicator. The stability indicator signals when maintenance or

reprogramming is needed during RUN mode.)

Amber (Output)

ON when the outputs are energized (conducting)

OFF when the outputs are de-energized (not conducting)

If contrast is marginal, the bi-color indicator flashes green (to indicate instability). Reprogramming the sensor, or cleaning the sensor lenses may solve a

problem with stability.

TEACH Mode

Program the SLE10 Expert—set the sensitivity and select output ON and OFF conditions—in TEACH Mode. The SLE10 Expert provides two methods for

programming: Static TEACH and Dynamic TEACH. Static TEACH is used in all programming situations to set up the sensor's output ON and output OFF

conditions. Sensitivity is then set using either the Static method or the Dynamic method.

Both Static TEACH and Dynamic TEACH may be performed using either the sensor's TEACH push button or the remote TEACH line.
