1st Taught

Condition

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.

Push button (0.04 seconds ≤ “Click” ≤ 0.8 seconds); Remote line (0.04

seconds ≤ “T” ≤ 0.8 seconds)

1. Access TEACH mode.

Method

Action

Result

Via push button

Press and hold push button until the bi-color (green/

red) indicator begins to flash red, or turns OFF.

Push button method only: The amber LED is on. The

red LED pulses to indicate relative received signal

strength. The sensor is ready for the output ON

condition.

Via remote line

No action required; sensor is ready for 1st sensing

condition.

2. Teach the first sensing condition.

Method

Action

Result

Via push button

Present the first sensing condition and click the push

button.

The amber LED is off. The red LED pulses to indicate

relative signal strength. The sensor registers the

output ON condition and is ready for the output OFF

condition.

Via remote line

Present the first sensing condition and single-pulse the

remote line.

3. Teach the second sensing condition and return to RUN mode.

Method

Action

Result

Via push

button

Present the second sensing condition

and click the push button.

If the teach is accepted the green LED is on (or flashes if the signal is

close to the switching threshold) and the amber LED is off until the

sensing condition changes; the sensor registers the output OFF

condition, positions the threshold, and returns to RUN mode.

If the teach is not accepted, the amber LED is on and the red LED pulses

to indicate the relative received signal strength. The sensor returns to its

wait state and is ready for the first sensing condition.

Via remote line Present the second sensing condition

and single-pulse the remote line.

NOTE: The sensor returns to RUN mode if the first TEACH condition is not registered within 90 seconds. TEACH mode may be

cancelled before either the first or second condition by holding the push button depressed for more than two seconds.

Enabling or Disabling the Push Button

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.

1. Connect the sensor’s gray wire.

2. Four-pulse the remote line to enable or disable the push button.

The sensor toggles between enable and disable settings and returns to RUN mode.
