Opposed-mode sensing is very reliable, and the single self-contained housing provides easy installation, with no sensor alignment required. In addition, the molded-in arrow on the emitter portion of the housing and the slotted design on the receiver portion of the housing show at a glance the position of the beam, simplifying installation placement. Expert series sensors feature easy-to-use push-button programming, performed in TEACH mode. TEACH-mode programming may be performed using either the push button, or remotely, using a remote switch or process controller. The programming determines whether the sensor outputs will conduct in light or dark conditions, and defines the light and dark conditions for the sensor in each application. The remote switch also may be used to disable the programming push button for security. The Dynamic TEACH option provides a means for teaching a series of conditions; the sensor monitors the sensing events and automatically sets the threshold between light and dark conditions. 1 To order the 9 m (30 ft) PVC cable model, add the suffix "W/30" to the cabled model number. For example, SLE30B6V W/30. Models with a quick disconnect require a mating cordset. SLE30 Expert Series Slot Sensor Original Document 58338 Rev. B

Programming is accomplished using a specified sequence of input pulses. The duration of each pulse is defined as: 0.04 seconds < T < 0.8 seconds. common (no press-and-hold procedure is required to enter TEACH mode). This is the equivalent of a click when using the sensor TEACH push button. Figure 3. Timing Programs for Remote Programming Pulse the Remote TEACH line four times (four-pulse) to enable or disable the push button. sensitivity to the optimum value for the application, and then returns to RUN mode. between the light and dark conditions. red, or turns OFF (longer than two seconds). by pressing the button for longer than or equal to 2 seconds. If push button is pressed for 2 seconds or longer, sensor automatically returns to RUN mode.

Present the first sensing condition to the sensor. b. Single-pulse the remote input. T Green/Red: Flash red or turn OFF (the AID™ function is indicating signal strength) Amber: Flash briefly, then turn off 3. TEACH Condition #2 (Output OFF state) Method Action Result Push Button a. Present the second sensing condition to the sensor b. Single-click the TEACH button. TEACH Accepted The sensor returns to RUN mode. TEACH Not Accepted The sensor returns to TEACH Condition #1. Green: ON (or flashes if signal is close to the switching threshold). Amber: OFF, until the sensing condition changes. Remote Input a. Present the second sensing condition to the sensor. b. Single-pulse the remote input. T TEACH Accepted The green indicator turns on and the sensor returns to RUN mode TEACH Not Accepted The amber indicator turns on and the red AID indicator remains active, indicating that the sensor is waiting for the first TECH condition to be taught again. (Run mode begins a few seconds after the end of TEACH mode.) Dynamic TEACH Dynamic TEACH is a method of setting the sensor's sensitivity while the object to be sensed is in motion. Typical applications are label sensing and small parts detection. In a label application, web flutter may change the amount of light passing through the label and its backing material. Dynamic TEACH will sense this variation and adjust the sensitivity to account for it. In a small parts detection application, alignment of the object to the sensor's effective beam may make Static TEACH difficult. In this case, Dynamic TEACH will allow you to pass individual or multiple parts through the beam; the sensor then will detect them and set the sensitivity automatically. Determine the Output ON and OFF Conditions Dynamic TEACH is used for optimizing the sensor's sensitivity and will not configure the output ON and OFF conditions. A Static TEACH must be used first to change the output ON and OFF conditions, if needed. If the outputs are configured properly for your installation, Dynamic TEACH may be performed as needed without reverting back to Static TEACH. Set Sensitivity Sensitivity is automatically set and optimized when the sensor is taught dynamically. When the push button is depressed and held, the sensor continues to sample events and registers them into memory. Upon release of the button, the sensor chooses the optimum setting for the application and then returns to RUN mode. Dynamic Sampling Rate When using Dynamic TEACH to sample an application for programming, it is important to consider the speed of the object being sensed. The sensor's sampling rate during this set-up process is much slower than its response time in RUN mode. Once sampling is complete and the sensor returns to RUN mode, sensor response time returns to its original value. Use the following formula to calculate the target object speed for Dynamic TEACH sampling: Maximum speed of object as it passes the sensor = [Width of the object (in inches) – effective beam (0.07 in)] ÷ Dynamic Sampling Rate (0.009 seconds)4 For example, for an object 0.125 inches wide, the maximum object speed is: 3 To exit Static TEACH without updating, hold the Remote TEACH line low (longer than 2 seconds) until the green indicator goes ON, before teaching the second target. 4 The Dynamic Sampling Rate for high-speed models ("Y" model suffix) is 8 milliseconds (0.008 seconds) .

(0.125 in – 0.07 in) ÷ 0.009 seconds = 6.1 in /second For an object 2 mm wide, the maximum object speed is: (2 mm – 1.8 mm) ÷ 0.009 seconds = 2.2 mm/second Dynamic TEACH When using remote TEACH, set up the application’s Output ON and OFF conditions using the Static TEACH procedure. This step is not necessary if the Output ON and OFF conditions already are configured properly for your application. 1.

TEACH Not Accepted The sensor returns to Static TEACH mode. Double click the TEACH button to initiate Dynamic TEACH. Green: ON (or flashes if signal is close to the switching threshold). Amber: ON or OFF, depending on condition Remote Input Release the Remote line when event sampling is complete. TEACH Accepted The green indicator turns on and the sensor returns to RUN mode with the new settings. TEACH Not Accepted Red: Flashes at a rate proportional to the received light signal strength Amber: ON, indicating the need to TEACH the sensor again. Return to step 2. 5 The sensor will return to RUN mode if the first TEACH condition is not registered within 90 seconds. Dynamic TEACH mode may be cancelled by waiting 90 seconds or by cycling sensor power. 6 For remote input, to exit Dynamic TEACH without updating, wait 90 seconds or cycle the sensor power.

The SLE30 Expert Power LED may begin to alternate flashing red/green; this indicates a microprocessor memory error. If it occurs, try re-teaching the sensor, or try cycling power ON and OFF, then re-teaching the sensor. If this does not solve the problem, or if it occurs frequently, replace the sensor.
