Teaching Limits Using the Auto-Window Feature
Teaching the same limit twice automatically centers a 20 mm window on the
taught position.
General Notes on Programming
• The sensor returns to Run mode if the first TEACH condition is not regis-
tered within 120 seconds.
• After the first limit is taught, the sensor remains in Program mode until the
TEACH sequence is finished.
• To exit Program mode without saving any changes, press and hold the pro-
gramming push button for more than 2 seconds (before teaching the sec-
ond limit). The sensor reverts to the last saved program.
