Installation

Installation and Alignment

MINI-BEAM sensors perform most reliably if they are properly aligned and
securely mounted. For maximum mechanical stability, final-mount MINI-BEAM
sensors through 18 mm diameter holes by their threaded barrel (where available),
or use a mounting bracket. A complete selection of mounting brackets is
available. Visit www.bannerengineering.com/69944, or contact the factory for
information on mounting options.

Begin with line-of-sight positioning of 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.

Apply power to the sensor (and to the emitter, if using the opposed mode).
Advance the 15-turn Gain control to maximum (clockwise end of rotation), using a
small flat-blade screwdriver. The Gain control is clutched at both ends to avoid
damage, and will “free-wheel” when either endpoint is reached. See MINI-BEAM
Sensor rear view illustration on page 2.

If the MINI-BEAM sensor is receiving its light signal, the red LED alignment
indicator will be ON and flashing at a rate proportional to the signal strength
(faster = more signal). 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 will
reduce the size of the movement zone, and enable more precise alignment.

Sensor Rear View

(shown with gasketed acrylic cover removed)

Repeat the alignment motions after each Gain reduction. When optimum
alignment is acheived, mount sensor(s) (and the retro target, if applicable) solidly
in that position. Increase the Gain to maximum.

Test the sensor by placing the object to be detected in the sensing position, then
removing it. The Alignment Indicator LED should come ON when the sensing
beam is established (Light condition), and go OFF when the beam is broken (Dark
condition).

1) With supplied fiber cutter, make a clean cut at control ends of fibers.

2) Unlock the fiber gripper as shown below. Apply appropriate fiber adaptors
prior to fiber insertion, if needed.

3) Gently insert the prepared fiber ends into the ports, as far as they will go.

4) Slide the fiber gripper back to lock, as shown below.

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 front of the sensor,
slide the U-shaped retaining clip (supplied with the sensor) into the slot in the
sensor’s barrel, until it snaps into place.
