BU 0V BK Q * Miniature design with front optical face * Automatic adjustment of sensitivity via TEACH-IN * Resistant against noise: reliable operation under all conditions * Certified by ECOLAB Release date: 2013-04-18 14:45 Date of issue: 2013-05-13 127469_eng.xml Product information Small, robust, effective, and reliable - these are the properties of the ML7 sensor series. Due to their small size, number of versions, and two different lens positions, they are particularly suited for installation in tight spaces. The robust design and high quality of Pepperl+Fuchs mean they can also be used under harsh environmental conditions. The efficient technology, switching frequencies up to 1000 Hz, high resistance to ambient light, and 4-in-1 output make the series suitable for non-contact object detection. = Light on = Dark on Indicators/operating means 3 1 2 Refer to "General Notes Relating to Pepperl+Fuchs Product Information".

The sensor operates at max. sensitivity (delivery status) or with the last teached values. Mount suitable reflector opposite light beam switch. Adjust the unit to the reflector. Press the Teach-In button - as an acknowledgement the green LED will quickly turn off one time. Press the Teach-In button until both LEDs green and yellow are blinking in parallel (2Hz). Release the Teach-In button now. While the green and yellow LEDs are blinking alternating (2 Hz) the unit is in the internal set up procedure. Teach-In successful: Both LEDs green and yellow are on. The unit is ready to use and in switching mode now. Teach-In not successful: Both LEDs are flashing alternating (4 Hz) for approx. 5 seconds. Afterwards the sensor returns to max. sensitivity setting. Please retry the Teach-In procedure beginning by step 1.
