Mode Switch
AUTO (Factory Setting)
Allows Self-Teach to be initiated with the pushbutton on the
sensor (Local) or through an external connection (Remote).
Sensor indicators and outputs are active and function normally.
Sensors may be operated in AUTO mode. Sensors must be
operated in AUTO mode when Remote Self-Teach is required.
SET
Allows self-teach to be initiated with the pushbutton on the
sensor (Local) only. The external Self-Teach connection
(Remote) is ignored. Sensor indicators function normally. Both
sensor and stability outputs are inhibited.
RUN
RUN mode is recommended for sensor operation in all
applications where Remote Self-Teach will not be used.
Sensor indicators and outputs are active and function normally.
No adjustments, Local or Remote, are possible while the
sensor is in RUN mode.
