• Present 1st sensing condition.
• Single-pulse remote line.
• Present 2nd sensing condition.
• Single-pulse remote line.
The two sensing conditions may be presented in either order. The condition presented
first is the condition for which the output will energize (the “Output ON” target).
Sensitivity is automatically set (and optimized) when teaching the sensor the ON and OFF
conditions. When the push button is clicked, the sensor samples each sensing condition
and registers it into memory. After the second sensing condition is registered, the MINI-
BEAM Expert automatically sets the sensitivity to the optimum value for the application,
and then returns to RUN mode.
In addition to its programming function, the remote line may be used to disable the push
buttons for security. Disabling the push buttons prevents undesired tampering with the
sensor configuration settings. Connect the sensor’s gray wire as described on page 4,
and four-pulse to either enable or disable the push buttons.
