Teaching Minimum and Maximum Limits
General Notes on Programming
• The sensor returns to Run mode if the first TEACH condition is
not registered 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 programming push button for more than 2 seconds (be-
fore teaching the second limit). The sensor reverts to the last
saved limits.
