Mount the Device

1. If a bracket is needed, mount the device onto the bracket.

2. Mount the device (or the device and the bracket) to the machine or equipment at the desired location. Do not tighten the mounting screws at

this time.

3. Check the device alignment.

4. Tighten the mounting screws to secure the device (or the device and the bracket) in the aligned position.

Sensor Alignment

Note: Follow proper electronic shock discharge (ESD) precautions when adjusting the Gain potentiometer or the LO/DO

switch.

Note: When turning the Light/Dark Operate Select switch, be careful not to damage the small tabs on the switch.

1. Using line-of-sight, position the MINI-BEAM sensor to its emitter (opposed-mode sensing) or to its target (all other sensing modes).

When using a retroreflective sensor, the target is the retroreflector (“retro target”). For diffuse or convergent sensing modes, the target is the

object to be detected.

2. Apply power to the sensor (and to the emitter, if using the opposed mode).

3. Using a small, flat-blade screwdriver, turn the 15-turn Gain control to maximum (the clockwise end of rotation).

The Gain control is clutched at both ends to avoid damage, and will “free-wheel” when either endpoint is reached.

If the MINI-BEAM sensor is receiving its light signal, the red LED Alignment indicator is ON and flashing at a rate proportional to the signal

strength (a faster flash rate = more signal).

4. Move the sensor (or move the retro target, if applicable) up-down-right-left, including angular rotation, to find the center of the movement

zone within which the LED indicator remains ON.

Reducing the Gain setting reduces the size of the movement zone and enables more precise alignment.

5. Repeat the alignment motions after each Gain reduction.

6. When optimum alignment is achieved, mount the sensor, and the emitter or retro target, if applicable, securely in that position.

7. Increase the Gain to maximum.

8. Test the sensor by placing the object to be detected in the sensing position, then removing it.

The Alignment indicator LED turns ON when the sensing beam is established (Light condition), and turns OFF when the beam is broken

(Dark condition). If the Alignment indicator LED stays ON for both sensing conditions, see the following tips for each sensing mode.
