Teaching Limits Using Two-Point Static TEACH
Two-Point TEACH is the traditional setup method, used when two conditions can be presented individually by the user. The sensor es-
tablishes a single sensing threshold (the switchpoint) midway between the two taught conditions, with the Output ON condition on one
side and the Output OFF condition on the other.
General Notes on Programming
• The sensor will return to RUN mode if the first TEACH condition is not registered within 60 seconds
• After the first limit is taught, the sensor will remain in PROGRAM mode until the TEACH sequence is finished
