Glass Fiber Installation

O-ring

Retaining Clip

1. Install the O-ring (supplied with the fiber) on each fiber end, as

shown in the drawing.

2. While pressing the fiber ends firmly into the ports on the sensor

front, slide the U-shaped retaining clip (supplied with the sensor)

into the slot in the sensor's barrel, until it snaps into place.

1. With supplied fiber cutter, make a clean cut at the control

ends of fibers.

2. Unlock the fiber gripper as shown in the drawing.

3. Apply appropriate fiber adaptors to the fiber, if needed.

4. Gently insert the prepared fiber ends into the ports as far

as they will go.

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.
