Teaching Limits Using the Auto-Window Feature

Teaching the same limit twice automatically centers a window on the taught position (see

on page 5 for window

sizes).
General Notes on Teaching

• The sensor will return to RUN mode if the TEACH condition is not registered within 120 seconds after the initial 2 second hold on the

Discrete push button.

• To exit TEACH mode without saving any changes, press and hold the Discrete push button or remote line longer than 2 seconds

(before teaching the second limit). The sensor will revert to the last saved limits.

• After the first limit is taught, the sensor will remain in TEACH mode until the TEACH sequence is finished or exited by a 2 second hold

on the Discrete push button or remote line.
