Banner MULTI-BEAM® sensors are compact modular self con-

tained photoelectric switches. Each MULTI-BEAM consists of

three components: scanner block, power block, and logic module.

The scanner block contains the complete modulated photoelectric

amplifier as well as the emitter and receiver optoelements. It also

contains the sensing optics and the housing for the other two

modules. The power block provides the interface between the

scanner block and the external circuit. It contains a power supply

for the MULTI-BEAM plus a switching device to interface the

circuit to be controlled. The logic module interconnects the power

block and scanner block both electrically and mechanically. It

provides the desired timing logic function (if any), plus the ability

to program the output for either light- or dark-operate. The

emitters of MULTI-BEAM emitter-receiver pairs do not require

a logic module. Emitter scanner blocks are supplied with a blade-

pin to interconnect the scanner block and power block. This

modular design, with field-replaceable power block and logic

module, permits over 5,000 sensor configurations, resulting in

exactly the right sensor for any photoelectric application.

There are two families of MULTI-BEAM sensors: 3- and 4-wire,

and 2-wire. Three- and four-wire MULTI-BEAMs offer the

greatest selection of sensor configurations. They permit either ac

or dc operation and offer the fastest response times and the

greatest sensing ranges. Two-wire MULTI-BEAMs are used in

ac-powered applications where simplicity and convenience of

wiring are important. They are physically and electrically inter-

changeable with heavy-duty limit switches.

The circuitry of all MULTI-BEAM components is encapsulated

within rugged, corrosion-resistant VALOX® housings, which

meet or exceed NEMA 1, 3, 12, and 13 ratings. Most MULTI-

BEAM scanner blocks include Banner's patented Alignment

Indicating Device (AID™) which lights a top-mounted LED

when the sensor sees its own modulated light source and pulses

the LED at a rate proportional to the received light signal. Most

MULTI-BEAM sensor assemblies are UL listed and certified by

CSA (see power block listings). All MULTI-BEAM components

(except power block models 2PBR and 2PBR2) are totally solid-

state for unlimited life.

MULTI-BEAM sensors are made up of three components: scanner

block, power block, and logic module. This is true for all MULTI-

BEAMs with the exception of opposed mode emitter units which

require only a power block (no logic module).

The first decision in the component selection process is to determine

which family of MULTI-BEAM sensors is appropriate for the applica-

tion: 3- and 4-wire, or 2-wire.

Next, decide which scanner block (within the selected family) is best for

the application. The guidelines in the catalog introduction will help you

to determine the best sensing mode. Then narrow the choice by

comparing the specifications listed in the following charts and on the

pages referenced in the charts.

Finally, choose a power block and logic module to complete the

MULTI-BEAM assembly. Components snap together without inter-

wiring to form a complete photoelectric sensing system that meets your

exact requirements while maintaining the simplicity of a self-contained

sensor.

If you have any questions about selecting MULTI-BEAM components,

please contact your Banner sales engineer or call Banner's Applications

Department at (612) 544-3164 during normal business hours.

DESCRIPTION

MULTI-BEAM 3- & 4-wire scanner blocks offer a complete comple-

ment of sensing modes. There are 3 or more models for each sensing

mode, resulting in a choice of exactly the right sensor for any applica-

tion. The high power models (10 millisecond response time) offer

greater optical sensing power than any other industrial sensors.

SPECIFICATIONS

SUPPLY VOLTAGE: input power and output connections are made

via a 3- or 4-wire power block (see pages 15 to 20).

RESPONSE TIME: 1 millisecond ON and OFF, except high gain

models with "X" suffix and ambient light receivers which are 10

milliseconds ON and OFF.

REPEATABILITY OF RESPONSE: see individual sensor specs.

SENSITIVITY ADJUSTMENT: easily accessible, located on top of

scanner block beneath o-ring gasketed screw cover. 15-turn clutched

control (rotate clockwise to increase gain).

ALIGNMENT INDICATOR: red LED on top of scanner block.

Banner's exclusive, patented Alignment Indicating Device (AID™)

circuit lights the LED whenever the sensor detects its own modulated

light source, and pulses the LED at a rate proportional to the received

light level.

CONSTRUCTION: reinforced VALOX® housing with components

totally encapsulated. Stainless steel hardware. Meets NEMA standards

1, 3, 12, and 13.

OPERATING TEMPERATURE RANGE: -40 to +70 degrees C

RETROREFLECTIVE

Mode SBLV1: visible beam makes alignment very easy, and is the first choice for most retroreflective applications.

Not for use in dirty environments; rather use opposed mode or see SBL1 & SBLX1, below. Do not locate

retroreflector closer than 6 inches (15cm) from sensor.

SBLVAG1: uses anti-glare filter for immunity to direct reflections from shiny objects. Use only with models

BRT-3 or BRT-1.5 retroreflective targets. Use only in clean environments. Do not locate retroreflector closer

than 12 inches (30cm) from sensor.

SBL1: use where invisible beam is advantageous (e.g. security applications or film processing). First choice for

retroreflective sensing in slightly or moderately dirty environments. Do not use when the object to break the

beam has a shiny surface, unless the angle of light to the surface can be predicted.

SBLX1: highest gain available in a retroreflective sensor. Use for all applications requiring more than 30-foot

range where opposed mode sensors cannot be used. Objects must pass at a distance of at least 10 feet from the

sensor to be reliably sensed.

NOTE: for detailed information on

available retroreflective materials, see

APPLICATION NOTE: as a general rule

regarding background objects in diffuse sens-

ing, verify that the distance to the nearest

background object is at least three times the

distance from the sensor to the object to be

sensed. For example, if a product passes one

inch from an SBD1 sensor, the nearest back-

ground object should be at least three inches

further away.

SBDX1: first choice for diffuse (proximity) mode applications when there is no requirement for less than 10 ms

response and where there are no background objects to falsely return light. High excess gain for reliable detection

of most materials with low reflectivity which pass within 10 inches (25cm) of the sensor.

SBDX1MD: wide beam angle for forgiving alignment to reflective objects. First choice for detection of clear or

translucent glass or plastics. High excess gain at close range, with fast fall-off of gain near the maximum sensing

distance for optical suppression of reflective background. This model may be created from model SBDX1 by

substituting upper cover (lens) model UC-DMB.

OBJECT

SBD1: short range diffuse mode sensor with relatively wide field of view. Loses gain rapidly near the end of its

range. As a result, its response to background objects is suppressed. However, use caution when applying any

diffuse mode sensor if background reflectivity exceeds the reflectivity of the object to be sensed.

SBDL1: longer range than SBD1, but with less response to objects passing the sensor at close range, and greater

sensitivity to background objects. Models SBD1 and SBDL1 are identical except for their upper cover (lens)

SBCV1: .06-inch (1.5mm) dia. visible red spot, for precise positioning, edge-guiding, & small parts detection.

Sensor-to-product distance must be consistent. Some products ≥1" tall may be sensed against immediate

background like parts on a conveyor. Excellent for high-contrast registration-sensing applications (except red-on-

white). Use with LM6-1 logic module for speed detection sensing gear teeth, pulley hubs, or chain links.

SBCVG1: .12-inch (3mm) diameter visible green spot. Use to detect color differences (e.g. color registration

marks), including red-on-white combinations. For subtle shade variations, use model FO2BG (see Banner product

catalog).

SBC1, SBC1-4, SBC1-6: infrared LED light source provides higher gain for reliable sensing of products of low

reflectivity, while controlling sensing depth of field. Does not offer the same precision possible with visible light

models. Good for sensing clear materials within the sensor's depth of field. Good for reliably counting the flow

of radiused products which are kept at a fixed distance from the sensor (e.g. bottles against conveyor guide rail).

SBCX1, SBCX1-4, SBCX1-6: these models offer the greatest optical gain available in any reflective mode sensor.

They reliably detect most non-reflective black materials in applications where opposed mode sensing is not

possible (e.g. web break monitoring). Not meant for ignoring background objects (see excess gain charts).

FIBER OPTIC Mode

(glass fiber optics)

OPPOSED FIBER OPTIC

Mode (glass fiber optics)

Model SBFX1 is the first choice for glass fiber optic applications, except in fiber optic retroreflective applications

or where faster response speed or visible light are a requirement. Model SBFX1 contains both emitter and receiver

and thus accepts either one bifurcated fiberoptic assembly or two individual fiber optic cables. The excess gain

of model SBFX1 is the highest available in the photoelectric industry. As a result, opposed individual fibers

operate reliably in many very hostile environments. Also, special miniature bifurcated fiber optic assemblies with

bundle sizes as small as .020 inch (.5mm) in diameter may be used successfully with model SBFX1 for diffuse

mode sensing. The excess gain curves and beam patterns illustrate response with standard .060 inch (1.5mm)

diameter and .12 inch (3mm) diameter bundles. Response for smaller or larger bundle sizes may be interpolated.

NOTE: opposed ranges shown are meant to illustrate excess gain only, and are limited by fiber length. Use scanner

block models SBEXF and SBRXF1 (above) for long range opposed fiber optic sensing.

HIGH-SPEED SCANNER BLOCK

Fiber optics are often used to sense small parts. Small parts or narrow profiles which move at a high rate of speed can require sensors with fast response times for

reliable detection. High speed fiber optic sensors are ideal for sensing gear or sprocket teeth or other targets in applications involving counters or shift registers for

position control. Selection of the fiber optic sensing tip should involve matching the effective beam of the fiber to the profile of the part to be sensed to maximize

the time that the part is sensed and/or the time between adjacent parts. Combining the best selection of fiber tip geometry with a high speed sensor will result in

a highly repeatable position sensing system. The model BT13S fiber optic assembly used with a model L9 or L16F lens and a high speed scanner block is an excellent

system for retroreflective code reading or for almost any short range retroreflective sensing application. Response time of a MULTI-BEAM sensor is also a function

of the power block. For this reason, only power blocks which switch dc (e.g. PBT, PBP, PBO, PBAT, etc) should be used if the fast response time of the scanner

block is to be utilized.

Convergent beam sensors like model SBCVG1 are often used for color registration sensing. However, there are

some registration applications where the use of bifurcated fiber optics is beneficial. Fiber optics are able to fit

into tight locations which are too small for a convergent sensor. Fibers also allow a choice of image size. It is

important to create an image size which is smaller than the registration mark in order to maximize optical contrast

and to ease sensor response requirements. Fibers allow a match of the light image to the geometry of the

registration mark. Scanner block model SBFVG1 will sense most bold color differences, including red-on-white.

Use only power blocks which switch dc (e.g. PBT, PBP, PBO, PBAT, etc.) for fast response.

Scanner block model SBFV1 supplies visible red light to the emitter half of a glass fiber optic photoelectric system. Visible light sensors have less optical energy

as compared to infrared systems. There are, however, some sensing situations which require visible light wavelengths in order to realize adequate optical contrast.

Opposed fibers using visible red light are used to reliably sense translucent materials (e.g. plastic bottles) which appear transparent to infrared opposed sensors. Fiber

assembly model BT13S used with a the model L9 or L16F lens makes an excellent visible light sensing system for retroreflective code reading as well as many short-

range retroreflective applications (e.g. retro scanning across a narrow conveyor). When combined with a bifurcated fiber, model SBFV1 may be used for color

registration sensing for applications where there is a large difference between the two colors (e.g. black-on-white). For combinations of red-on-white, however,

the visible-green light source of model SBFVG1 (below) is needed. Visible light emitters are also helpful for visual system alignment and maintenance.

HIGH SPEED MODIFICATION "MHS": scanner blocks with 1 millisec-

ond response may be modified for 300 microsecond (0.3 millisecond) response.

This modification is designated by adding suffix "MHS" to the scanner block

model number (e.g.- SBF1MHS, etc.). High speed is most often required in

fiberoptic or opposed mode sensing. The MHS modification reduces the

available excess gain by about 50%, and also decreases the sensor's immunity

to some forms of electrical "noise".

ZERO HYSTERESIS MODIFICATION "MZ": amplifier hysteresis may

be removed from 3- and 4-wire scanner blocks when attempting to sense very

small signal changes (contrasts less than 3). This modification is designated by

adding suffix "MZ" (Modified Zero Hysteresis). Be sure that all variables

affecting the sensor's optical response remain constant before ordering the zero

hysteresis modification .

These scanner blocks are non-modulated receivers which are operated by sunlight or incandescent, fluorescent,

infrared, or laser sources. A typical application would involve mounting the scanner block underneath a roller

conveyor, "looking" up between the rollers at the overhead factory lighting. Any objects passing over the sensor

would then cast a shadow, resulting in an output (dark operate). Ambient receivers are used with LM5-14 delay

logic to sense daylight for outdoor lighting control. These sensors can also sense the large amounts of infrared light

(heat energy) which is emitted by hot or molten glass, metal, or plastic during processing of these materials.

Model SBAR1 is for general application. Model SBAR1GH is a high gain version. It is about twenty times more

sensitive to light as compared to the SBAR1. The range at which either model will sense a light source depends

upon both the intensity of the light source and the contrast in intensity between the source and the rest of the ambient

light in the viewing area.

NOTE: ambient receiver scanner blocks will also work with 2-wire power blocks and logic. However, the light/

dark operate functions will be reversed when using 2-wire components.

SBAR1GH

Response: 10ms on/off

Amplifier: high gain

Optical response: ultra-

Model SBAR1GHF is identical to model SBAR1GH (above) except that it is equipped with an upper cover

assembly (model UC-RF) which allows an individual glass fiber optic assembly to be attached to the receiver

optoelement. This model is used for ambient light detection in locations which are either too confined or too hot

for mounting of the complete scanner block. A typical application involves sensing product presence or counting

during processing of red-hot or molten glass or metal. The addition of an L9, L16F, L16FAL, or L16FSS lens to

a threaded fiber assembly (e.g. IT23S) can narrow the angle of light acceptance to less than the angle of the SBAR1

lens. The high gain amplifier of model SBAR1GHF helps to offset light losses which are experienced with

fiberoptic light pipes. NOTE: glass fibers will not efficiently pass ultraviolet wavelengths.

MULTI-BEAM 3- & 4-wire power blocks provide regulated low voltage DC power to

the scanner block and logic module, and a solid state infinite-life switch (except in

emitter-only scanner blocks). Connections are made to heavy-duty screw terminals

which accept up to #14 gauge wire (no lugs are necessary). All power blocks are epoxy-

encapsulated and rated for -40 to +70 degrees C. Response times are determined by

the scanner block used, except that power blocks switching ac require up to 8.3

milliseconds to turn OFF in addition to the response time of the scanner block (plus

logic module time delays, if any).

Photo shows DC power block (left) and AC power block (right).

DC power blocks have gray housings; AC models are red.

PBP: similar to model PBT, except that it provides a PNP sourcing type output transistor. Sourcing

outputs are frequently required when interfacing to logic systems and programmable logic controllers

(PLCs) which require a positive source of dc voltage to generate an input condition. This type of interface

may also be accomplished by using PBT with a "pullup" resistor installed between terminals #1 and #3.

PBT: the most commonly used dc power block. Its output is an NPN transistor, which sinks current to

the negative side of the power supply. The load is connected between the output and the positive side of

the power supply. Switching capacity is 250mA. There is no connection to terminal #4.

PBT48: exactly the same configuration as the PBT, but for 48V dc systems.

PBT2: provides two NPN outputs; one normally open, the other normally closed (equivalent to SPDT

relay). The normally closed output may be used when a load must de-energize when the MULTI-BEAM

operates (e.g. normally closed one-shot). NOTE: both outputs are open when dc power is removed.

DC Models

These are power blocks for emitter scanner blocks only (models SBE, SBED, SBEX, SBEV, SBEXD, SBEF, SBEXF). Emitter assemblies do

not require logic modules.

When using power blocks with current sinking (NPN)

outputs, simple loads connect between the power block

output (terminal #3) and the positive supply (terminal

#1).

MULTI-BEAM emitter-only scanner blocks use dc power

block models PBT-1 or PBT48-1. These power blocks

connect directly across the dc supply, as shown.

Any number of MULTI-BEAMs may be connected in parallel to one load to create "LIGHT-OR" (light operate

mode) or "DARK-OR" (dark operate mode) multiple sensor logic. In most situations, MULTI-BEAM dc power

blocks cannot wire in series. However, addition of an interposing relay with a normally closed contact or a Banner

logic module will permit "AND" logic with a parallel sensor array.

When using power blocks with current sourcing (PNP)

A logic zero (0 volts dc) is applied to the gate input

when the MULTI-BEAM output is energized. When

de-energized, a logic one is applied. The logic supply

must be common to the MULTI-BEAM supply nega-

tive.

PBD-2 These power blocks are the most commonly used for ac operation. As the typical hookup

However, the output of all four blocks is rated for 250V ac maximum, and all can switch a

voltage which is different than the supply as long as both ac circuits share a common neutral.

For example, a PBA could switch a 24V ac door chime, etc. Observe local codes when mixing

ac voltages in a wiring chamber. These blocks are designed to handle the inrush current of ac

inductive loads like motor starters and solenoids. The "holding current" specification of any

inductive load should not exceed the 750mA output rating. There is no minimum load

requirement. These power blocks will interface directly to all ac programmable controller

inputs. All contain built-in transient suppression to prevent false turn-on or damage from

inductive loads and line "spikes". Outputs of multiple power blocks may be wired in series or

parallel for "AND" and "OR" logic functions.

PBAM

PBOB

PBO

Model PBAM is a special-purpose power block that is powered by 120V ac, and provides a low level source

of dc output voltage when the sensor's output is energized. It is used primarily to power low voltage audio

tone annunciators such as "SONALERTS". The PBAM may also provide a signal to many types of logic

devices. The output is approximately 8V dc when energized, and the output impedance is 1K ohm (short

circuit proof). The output is totally isolated from the ac supply voltage, and may be used to provide an input

signal to many line-powered or battery-powered electronic totalizers.

Input: 105 to 130V ac, 50/60Hz.

Output: 8Vdc at 8mA maximum (short

circuit proof).

Input: 210 to 250V ac, 50/60Hz.

Input: 105 to 130V ac, 50/60Hz.

These power blocks are designed to interface an electronic circuit (or control) at a low dc voltage level, but

where there is no dc supply voltage available to power the MULTI-BEAM. Since the output is isolated

it may be wired to either source or sink current, and multiple units may be wired in either series or parallel.

The output of model PBO or PBOB will directly interface Banner component system logic modules. The

low on-state saturation voltage allows direct interfacing to most solid-state low voltage dc logic systems

or electronic totalizers.

Note: the 1-volt saturation prevents direct interfacing to 5-volt logic systems like TTL. For these low-

voltage interfaces, use instead special order power block model PBOL or PBOBL.

AC Models Connections

Power block models PBAT and PBBT have an isolated solid-state output switch which may be used

to switch either ac or dc. The switch is rated at 100mA maximum, and there is no capacity for inrush.

As a result, these power blocks usually should not be used to switch ac inductive loads. However,

100mA is enough capacity to switch many inductive dc loads like small relays and solenoids. Models

PBAT and PBBT interface directly to all ac programmable controller inputs.

Since the saturation voltage of these power blocks is typically greater than 1 volt, they should not be

used to interface 5V dc logic circuits like TTL. Instead, use special order model PBOL or PBOBL.

NOTE: add 8.3 milliseconds to the off-time response of the scanner block.

Hookup Diagrams for AC Power Blocks

Model PBAQ is identical to model PBA (page 17) except that the solid-state output contact is

normally closed instead of normally open. It is used where it is necessary to have the load de-

energize when something is sensed (e.g.- one shot pulse to de-energize load). When no timing

logic is involved, model LM3 can program any power block for normally open or normally

closed operation via the light/dark operate jumper. NOTE: model PBAQ is not comaptible

with logic module models LM5 and LM5-14. For normally closed on-delay logic, use PBA

with LM5R and reverse the light/dark function.

Hookup of an AC EmitterHookup to a Simple AC Load

AC voltage is connected to terminals #1 and #2 to provide power to the MULTI-BEAM. The solid-state output

switch behaves as if there were a contact between terminals #3 and #4. L1 is most conveniently applied to

terminal #3 by jumpering terminals #1 and #3 inside the MULTI-BEAM.

The outputs of all five power block models are rated

for 250V ac maximum, and can switch an ac voltage

which is different from the supply as long as both ac

circuits share a common neutral. Observe local

wiring codes when mixing AC voltages in a common

wiring chamber.

Since the output switch is a solid-state device, con-

tact continuity cannot be checked by means of an

ohmeter, continuity tester, etc. To check the func-

tioning of the output switch, a load must be installed

and tested along with the MULTI-BEAM.

CAUTION: the output switch could be destroyed if

the load becomes a short circuit (i.e., if L1 and L2 are

connected directly across terminals #3 and #4).

NOTE: this hookup depicts the output switch as a

normally open contact. Model PBAQ actually has a

normally closed output switch.

Hookup to a Programmable Logic Controller (PLC)

LM4-2 one-shot (retriggerable) The LM4-2 provides a one-shot ("single shot") output pulse each time there is a transition from

LIGHT to DARK (jumper installed) or from DARK to LIGHT (jumper removed). The output

pulse time range is adjustable from 0.1 to 1 second. The duration of the pulse is independent of

the duration of the input signal. The timing of the LM4-2 is restarted each time the input signal

is removed and then recurs. This is referred to as a "retriggerable" one shot, and this feature may

be applied to some rate sensing applications (use LM6-1 for true rate sensing).

LM1 is an on-off logic module that causes the power block output to "follow the action" of the

scanner block: when the scanner block sees a LIGHT signal, the output is energized; when the

scanner block sees a DARK signal, the output is de-energized. This is referred to as the LIGHT

operate mode. If the application calls for DARK operate mode, the LM1 may be used with

normally-closed type power blocks such as PBAQ or PBT2.

LM3 on-off

Specifications, 3- and 4-wire Logic Modules

The logic module interconnects the power block and scanner block both electrically and

mechanically using a unique blade-and-socket connector concept. It also provides the

LIGHT/DARK operate function (except in the LM1) and the timing functions, all of which

are fully adjustable.

In the diagrams below, the "signal" represents the light condition (in LIGHT operate) or

the DARK condition (in DARK operate), and the "output" represents the energized

condition of the solid-state output switch (power block). "Delay" refers to the time delay

before the output operates, and "hold" refers to the time that the output remains "on" after

the event has occurred.

The photo (left) shows a typical logic module for 3- or 4-wire operation. Note that all 3-

& 4-wire logic modules are color-coded red. The time ranges listed for the logic modules

in the table below are standard time ranges. Other time ranges are available; see page 23

for information.

The LM2 provides "flip-flop" or toggling action of the power block output, such that each time

the scanner block changes from a DARK state to a LIGHT state, the output changes state. The

output remains in the last state until another change occurs. The LM2 is frequently used to operate

a diverter gate that splits a production line into two lines. It may also be used to operate room

lighting by breaking a photoelectric beam: if the lights are OFF, breaking the beam turns them

ON; if the lights are ON, breaking the beam turns them OFF.

The LM3 is an on-off logic module that has the ability to be programmed for either LIGHT

operate or DARK operate. It comes with a jumper wire installed: with the jumper in place, the

output is DARK operated; with the jumper removed, the output is LIGHT operated. The LM3

is the most commonly used logic module when no timing function is desired, particularly if it is

not known at the time of ordering which mode (LIGHT or DARK operate) will be needed.

The LM5 is a true "on-delay" type logic module. The input signal must be present for a

predetermined length of time before the output is energized. The output then remains energized

until the input signal is removed. If the input signal is not present for the predetermined time

period, no output occurs. If the input signal is removed momentarily and then reestablished, the

timing function starts over again from the beginning. A LIGHT/DARK operation selection

jumper is included. The standard time range is adjustable from 1.5 to 15 seconds (field

adjustable), and other ranges are available. The LM5 is often used to detect jams on a conveyor

line, where a beam broken for longer than a preset period of time implies a product jammed in

the light beam.

The LM5-14 combines the function of an "on-delay" and an "off-delay" into one logic module.

When the signal is present for more than the on-delay time, the output energizes. The off-delay

circuit is now active, and holds the output on even if the input signal disappears for short periods

of time. If the input signal is gone for longer than the off-delay time, the output finally drops out.

The most common use for the LM5-14 is to control fill level, for example in a bin: when the bin

is full, a beam is broken, and a predetermined time later, the flow is stopped. After the level has

fallen below the beam for a time, the flow is restarted. The time delays control the high and low

levels. Each delay is independently adjustable for 1.5 to 15 seconds.

The LM5T "limit" timer combines the function of on-off logic and on-delay logic. As long as

the signal is present for only short periods of time, the output "follows the action" of the input

signal. If the input signal is present for longer than the predetermined time, the output

deenergizes. The output only reenergizes when the input signal is removed and then reestab-

lished. Interval timers are used to operate loads which must not run continuously for long periods

of time, such as intermittent duty solenoids and conveyor motors. The LM5T may be used to run

a supermarket checkout conveyor, always bringing the product up to the sensor beam and then

stopping the motor. When the last item is removed, the motor times out and stops. Timing range

is .15 to 15 seconds.

The LM6-1 is a true overspeed or underspeed sensing logic module that monitors signals from

a scanner block and continuously calculates the time between input signals, and compares that

time with the reference set by the "HOLD" potentiometer. A jumper allows the mode to be

changed from overspeed (jumper installed) to underspeed (jumper removed). In the overspeed

mode, the output will drop if the preset rate is exceeded. In the underspeed mode, the output

remains energized until the input rate drops below the preset. The output will not "pulse" at low

speeds as retriggerable one-shots do. A "DELAY" adjustment allows the LM6-1 to ignore data

for the first several seconds after power is applied, to permit the rate to accelerate to operating

speed without false underspeed outputs. The sensing rate may be adjusted from 60 to 1200 pulses

per minute (.05 to 1.0 second per pulse), and the power-up inhibit from 1 to 15 seconds.

The LM5R is an "off-delay" logic module, similar to the LM5, except that timing begins on the

trailing edge of the input signal. When the input occurs, the output is immediately energized; if

the input is then removed, the output remains energized for the adjustable pre-determined time

period, then de-energizes. If the input is removed but then re-established while the timing holds

the output energized, a new output cycle is begun. The LM5R might typically be used to tell when

no products have broken a beam for a predetermined length of time, therefore indicating a jam

or an empty reservoir upstream. The LIGHT/ DARK operate jumper wire is included. Timing

range is adjustable from 1.5 to 15 seconds, and optional ranges are available.

The LM4-2NR provides a one-shot ("single shot") output pulse each time there is a transition

from LIGHT to DARK (jumper installed) or from DARK to LIGHT (jumper removed). The

output pulse time range is adjustable from 0.1 to 1 second. The duration of the pulse is

independent of the duration of the input signal. The output pulse of the LM4-2NR must complete

before it recognizes another input transition. This is called a "non-retriggerable" one shot, which

sometimes offers an advantage in indexing or registration control applications where multiple

input signals are possible during advance of the product.

LM8 repeat cycler

Model and Function Description of Logic

The LM8 is a repeat cycle timing module with independently adjustable delay and hold times.

When an input signal is received from the scanner block, a delay period begins during which there

is no output. If the signal remains, the delay period is followed by a hold period, during which

the output is energized. If the signal still remains, the hold period times out, releasing the output

and starting a new delay period. This sequence continues indefinitely until the input signal is

removed. The LM8 is used in edgeguide and other registration control schemes where it is desired

to "pulse" the correction motor to avoid overcorrection that might occur with a continuous output.

Both time ranges are indpendently adjustable from 1.5 to 15 seconds. NOTE: use of the LIGHT/

DARK operate jumper is reversed: remove for DARK, leave in place for LIGHT.

The LM8-1 is a delayed one-shot that functions very much like two individual one-shots, with

the end of the first initiating the second. When an input signal occurs, a delay period is initiated,

during which time the output is not energized. After the delay, the output is energized for the hold

period, then deenergized. No further action takes place unless the signal is removed and then

reestablished. This sequence is independent of the duration of the input signal. The LM8-1 is

frequently used to sense a product, and then act on that product a short time later when it is clear

of the inspection station. An example might be to inspect cartons for open flaps, and to eject the

faulty cartons when they have completely passed the inspection point. Both time ranges are

adjustable from 1.5 to 15 seconds.

The LM8A differs slightly from the LM8-1. It too incorporates both a delay and a hold time,

except that the delay is a true on-delay. If the input signal does not last for the total duration of

the delay time, no output action ever occurs (with the LM8-1, even a momentary signal generates

one complete cycle of timing). If the delay time passes, the one-shot output occurs, regardless

of what happens to the input signal. Removing the input signal and reapplying it begins a new

cycle. The LM8A is used to eject a part that has remained in the sensor beam longer than the delay

time (for instance, a jammed part). Both time ranges are independently adjustable from 1.5 to

15 seconds. NOTE: use of the LIGHT/ DARK operate jumper is reversed: remove for DARK,

leave in place for LIGHT.

The LM10 is a fixed-count divide-by-ten logic module, with neither timing nor LIGHT/ DARK

operate functions. When power is first applied, the output is OFF; with each dark-to-light

transition, the LM10 enters one count in its memory. After five counts, the output is energized,

and it remains energized until the tenth count. It then deenergizes, and the sequence continues.

The LM10 is intended for product counting applications using programmable logic controllers

or computers, where the scan time of the input section of the controller is too slow to permit

"catching" high speed count rates. It may also be used with electromechanical totalizers, which

suffer from this same slow response. In operation, of course, the registered count must be

multiplied by ten to get the true count (ambiguity of five).

LMT is a plug-in test logic module for use when troubleshooting MULTI-BEAM sensors. It

contains LED indicator lights in place of the timing potentiometers and a miniature switch in place

of the LIGHT/DARK operate jumper. The indicator lights display the operation of the scanner

block and power block to verify proper functioning, and the switch permits manual operation of

the load to verify the output switching circuit. The step-by-step testing procedure included with

the LMT will allow a MULTI-BEAM to be completely tested without removing it from the

installation, and, if there is a faulty scanner block, power block, or logic module, the LMT will

identify it. The LMT may also be used with all 2-wire MULTI-BEAMs (see pages 24 to 29).

• For logic modules with a single timing function, specify the maximum

desired time in seconds (e.g., LM5M5 indicates an LM5 on-delay with the delay

time adjustable up to 5 seconds).

• For logic modules with dual timing functions, specify the maximum desired

delay and hold time in seconds (e.g., LM5-14M1M5 indicates an LM5-14 on-

off delay with an on-delay adjustable up to 1 second and an off-delay adjustable

up to 5 seconds). Always specify both timing ranges, even if only one is to be

modified.

• For fixed timing, the letter "F" should always be followed by the desired time,

in seconds (e.g., LM5MF1 would be an LM5 on-delay with a fixed 1 second

delay time). For fractions of seconds, use decimal equivalents, such as

LM5MF.5, or LM5MF.01, etc.

MULTI-BEAM 3- & 4-wire Logic Modules

The time ranges of any MULTI-BEAM 3- & 4-wire logic module may be

factory modified. Time range modification is often necessary to improve the

setability of the timing function. Some time range modifications are carried in

stock. The current Banner products price list is the best source of this

information. Other time range modifications may be quoted. When ordering

modified logic modules, add the letter "M" after the model number, followed

by the maximum time desired (in seconds). The table below lists possible

modifications.

2-wire MULTI-BEAM

MULTI-BEAM 2-wire Sensors

The components of the MULTI-BEAM 2-wire family of modular self-contained

sensors are physically identical to the 3- & 4-wire components. However, the 2-

wire components are designed to wire directly in series with an ac load, exactly

like a limit switch. This design makes the 2-wire MULTI-BEAM impossible to

wire backward.

MULTI-BEAM 2-wire scanner blocks with their 10 millisecond response time

have approximately the same optical performance as the 1-millisecond 3- & 4-

wire scanner block models.

The off-state leakage current of 2-wire MULTI-BEAM sensors is less than 1

milliamp, the lowest value of any 2-wire photoelectric sensor. This makes the

MULTI-BEAM 2-wire photoelectric device the most probable such device to

interface directly with ac inputs of programmable logic controllers (PLCs).

Functional Schematic, 2-wire MULTI-BEAM

ALIGNMENT INDICATOR: red LED on top of scanner block.

Banner's exclusive, patented Alignment Indicating Device (AID™)

circuit lights the LED whenever the sensor detects its own modulated

light source, and pulses the LED at a rate proportional to the received

light level.

CONSTRUCTION: reinforced VALOX® housing with components

totally encapsulated. Stainless steel hardware. Meets NEMA stan-

dards 1, 3, 12, and 13.

OPERATING TEMPERATURE RANGE: -40 to +70 degrees C

(-40 to +158 degrees F).

SUPPLY VOLTAGE: connections are made via a 2-wire power

block (see page 27).

RESPONSE TIME: 10 milliseconds ON and OFF (3000 operations

per minute). NOTE: a built-in false pulse protection circuit holds the

output off for 100 milliseconds after power is initially applied to the

sensor.

REPEATABILITY OF RESPONSE: see individual sensor specs.

SENSITIVITY ADJUSTMENT: easily accessible, located on top of

scanner block beneath o-ring gasketed screw cover. 15-turn clutched

control (rotate clockwise with a small screwdriver to increase gain).

Model 2SBR1 receiver is used with the SBE emitter, which is the same emitter used with the 1 millisecond 3- &

4-wire receiver model SBR1. The response time, however, is determined by the receiver, and is 10 milliseconds.

This pair will work reliably in slightly dirty (average manufacturing plant) conditions up to 60 feet opposed, and

outdoors up to 20 feet. When more distance (or excess gain) is required, use 3- & 4-wire receiver model SBRX1

with the SBEX emitter. The 2SBR1 will not work with the visible emitter SBEV. Use opposed mode sensors as

a first choice in any application, except where the material to be sensed is translucent to light or so small that it

will not break the effective beam diameter. The SBE emiter uses a 3 & 4 wire power block. Powerblocks for use

with SBE include models PBA-1, PBB-1, PBD-1, PBT-1, and PBT48-1 (see pages 16 and 19 for information on

these powerblocks).

Model 2SBL1 is the retroreflective mode scanner block in the 2-wire MULTI-BEAM family. It has the same

excellent optical performance as model SBL1 in the 3- & 4-wire family. If the application calls for breaking a

retroreflective beam with shiny objects such as metal cans or cellophane-wrapped packages, mount the 2SBL1

and its retroreflector at an angle of 10 degrees or more to the shiny surface to eliminate any direct reflections from

the object itself, or consider using 3- & 4-wire scanner block model SBLVAG1 (page 8). Alternatively, the MAXI-

BEAM, VALU-BEAM, and MINI-BEAM families offer 2-wire ac visible and polarized retroreflective models.

Notice from the excess gain curve that the gain falls off at very close sensing ranges, so much so that retroreflectors

cannot be used reliably closer than one inch from the sensor.

These convergent mode 2-wire scanner blocks are identical in performance to their 3- & 4-wire equivalents,

except for the 10 millisecond response time. They are designed for 2-wire applications where background objects

might be seen by proximity mode sensors, or where the precision of a small focused image is important (e.g.- edge-

guiding or position control). Model 2SBC1 provides much more excess gain at its focus point as compared to the

diffuse mode sensors. Convergent mode sensors are preferable to diffuse mode sensors if the distance from the

sensor to the object to be detected can be kept constant. Models 2SBC1 and 2SBC1-4 may be derived from retro

model 2SBL1 by exchange of the upper cover assembly. Model 2SBC1 uses upper cover UC-C, and model

2SBC1-4 uses upper cover model UC-C4. These may be interchanged. A 6-inch convergent model may be created

from either model by substituting upper cover UC-C6. See the Upper Cover Interchangeability Chart in the

Banner product catalog for more information.

Scanner block 2SBF1 com-

bines the simplicity of 2-

wire hookup with the so-

phistication and versatility

of optical fibers. The infra-

red source of this model will

work with any Banner glass

fiber optic assembly, except

bifurcated assemblies with

bundle diameters less than

1/16". Since fibers are fre-

quently used for sensing

small parts, fast response

time is often a considera-

tion. If the application re-

quires response near the 10

millisecond specification of

the 2SBF1, consider the

faster 3- & 4-wire model

SBF1.

Models 2SBD1 and 2SBDX1 diffuse (proximity) mode scanner blocks are identical except for their lenses. Model

2SBD1 uses upper cover model UC-D, and the 2SBDX1 uses UC-L (see MULTI-BEAM Accessories, pages 30-

31). While the UC-L lens extends the range to over 30 inches, it creates a "dip" in the excess gain at closer ranges.

As a result, the 2SBDX1 may sense a dark colored object at 10 inches, but it may not see it at all at 2 inches. If

the application is not completely defined, either scanner block may be ordered, along with the complementary

upper cover as an accessory.

MULTI-BEAM 2-wire power blocks offer the ultimate in simplicity of sensor hookup. They wire

directly in series with an ac load, exactly like a limit switch. Response time of 2-wire power

blocks is determined by the scanner block, which is 10 milliseconds on/off. A built-in false pulse

protection circuit holds the output OFF for 100 milliseconds after power is initially applied to the

power block. 2-wire power blocks will operate from -40 to +70 degrees C (-40 to +158 degrees

F). Resistive loads must be less than 15,000 ohms and inductive loads must be greater than 1.2

watts (10 milliamps).

Model 2PBR actually requires a 4-wire hookup and model 2PBR2 requires a 3- or 4-wire hookup,

even though they only work with 2-wire scanner blocks and logic modules. Both are powered by

120V ac across terminals #1 and 2. The 2PBR offers an SPST "hard" relay contact between

terminals #3 and 4. Model 2PBR2 is an SPDT version, with both contacts common to terminal

#1: terminal #3 is a normally open output, and terminal #4 is normally closed. These

configurations allow MULTI-BEAM sensors to directly interface large loads which draw more

than 3/4 amp like clutches, brakes, large contactors, and small motors. Model 2PBR can switch

both ac and dc loads; model 2PBR2 switches the ac line voltage to an ac load (see connection

diagrams). The 2PBR and 2PBR2 also eliminate the problem of voltage drop from series strings

of sensors operating low voltage ac loads. NOTE: install an appropriate value MOV (metal oxide

varistor) transient suppressor across the power block relay contacts when switching an ac

inductive device.

Functional Schematics

MULTI-BEAM 2-wire power block models 2PBA, 2PBB, and 2PBD contain a low voltage power supply which

utilizes a unique circuit to take a very small leakage current through the load and convert it to the dc power required

to run the scanner block and logic module. They also contain the solid-state switch that operates the load, and a

transient suppression circuit to prevent false operation from high voltage spikes on the incoming line. They are

completely solid-state for unlimited operating life.

Model 2PBR is a 4-wire power block which works with 2-wire scanner blocks and logic modules and offers an SPST

"hard" contact for switching heavy ac or dc loads. Model 2PBR2, also for use with 2-wire scanner blocks and logic

modules, uses a 3- or 4-wire hookup with SPDT "hard" contacts for switching heavy ac loads.

NOTE: MULTI-BEAM 2-wire ac power blocks are color-coded black.

MULTI-BEAM 2-wire sensors operate with very

low (1 milliamp) off-state leakage current. As a

result, they will interface directly to most PLCs

without the need for an artificial load resistor. If

the off-state voltage (1mA x input resistance of

the PLC) is higher than the PLC sensing thresh-

old, install a 10KΩ to 15KΩ, 5-watt resistor for

each 2-wire sensor. The resistor connects be-

tween the input terminal and ac neutral.

brand of PLC, contact the Banner Applications

Department during normal business hours.

MULTI-BEAM 2-wire sensors wire in series with an appropri-

ate load. This combination, in turn, wires directly across the ac

line. A 2-wire sensor may be connected exactly like a mechani-

cal limit switch.

The MULTI-BEAM remains powered when the load is "off" by

a residual current which flows through the load. This off-state

leakage current is always less than 1 milliamp. The effect of this

leakage current depends upon the characteristics of the load. The

voltage which appears across the load in the off-state is equal to

the leakage current of the sensor multiplied by the resistance of

the load: V (off)= 1mA x R(load)

If this resultant off-state voltage is less than the guaranteed turn-

off voltage of the load, the interface is direct. If the off-state

voltage causes the load to stay "on", an artificial load resistor

must be connected in parallel with the load to lower its effective

resistance. Most loads, including most programmable logic

controller (PLC) inputs, will interface to 2-wire sensors with

1mA leakage current without the need for an artificial load

resistor. There is no polarity requirement. Either wire may

connect to terminal #1, and the other to terminal #2.

CAUTION: all three components of a MULTI-BEAM 2-wire

sensor will be destroyed if the load becomes a short circuit!!

Basic Hookup of 2-wire MULTI-BEAM Multiple 2-wire MULTI-BEAMs may be wired together in

parallel to a load for "OR" or "NAND" logic functions.

When sensors are wired in parallel, the off-state leakage

current through the load is equal to the sum of the leakage

currents of the individual sensors. Consequently, loads with

high resistance, like small relays and electronic circuits, may

require artificial load resistors.

2-wire MULTI-BEAM sensors have a 100 millisecond

power-up delay for protection against false outputs. When

2-wire MULTI-BEAMs are wired together in parallel, any

power block which has an energized output will rob all of the

other power blocks of the current they need to operate.

When the energized output drops, there will be a 0.1 second

delay before any other MULTI-BEAM can energize. As a

result, the load may momentarily drop out.

2-wire MULTI-BEAM sensors cannot wire in series with

other 2-wire sensors unless power block model 2PBR is

used. If series connection of 2-wire ac sensors is required,

consider models within the VALU-BEAM or MINI-BEAM

families.

2-wire MULTI-BEAM

in Series with Contacts 2-wire MULTI-BEAM

in Parallel with Contacts

When 2-wire MULTI-BEAM sensors are con-

nected in series with mechanical switch or relay

contacts, the sensor will receive power to operate

only when all of the contacts are closed. The

false-pulse protection circuit of the MULTI-

BEAM will cause a 0.1 second delay between the

time that the last contact closes and the time that

the load can energize.

2-wire MULTI-BEAM sensors may be wired in

parallel with mechanical switch or relay con-

tacts. The load will energize when any of the

contacts close or the sensor output is energized.

When a contact is closed, it shunts the operating

current away from the MULTI-BEAM. As a

result, when all of the contacts are open, the

MULTI-BEAM's 0.1 second power-up delay

may cause a momentary drop-out of the load.

MULTI-BEAM 2-wire Logic Modules

The 2LM3 is an on/off logic module that has the ability to be programmed for either LIGHT

or DARK operate. It comes with a jumper wire installed: with the jumper in place, the output

is DARK operated; with the jumper removed, the output is LIGHT operated. The 2LM3 is

used when no timing function is desired.

The 2LM4-2 provides a one-shot ("single shot") output pulse each time there is a transition

from LIGHT to DARK (jumper installed) or from DARK to LIGHT (jumper removed). The

output pulse time range is from adjustable from 0.1 to 1 second. The duration of the pulse

is independent of the duration of the input signal. The timing of the 2LM4-2 is restarted each

time the input signal is removed and then recurs. This is referred to as a "retriggerable" one

shot, and this feature may be applied to some rate sensing applications.

The 2LM5 is a true "on-delay" type logic module. The input signal must be present for a

predetermined length of time before the output is energized. The output then remains

energized until the input signal is removed. If the input signal is not present for the

predetermined time period, no output occurs. If the input signal is removed momentarily

and then reestablished, the timing function starts over again from the beginning. The

standard time range is adjustable from 1.5 to 15 seconds, and other ranges are available.

The 2LM5R is an "off-delay" logic module, similar to the 2LM5, except that timing begins

on the trailing edge of the input signal. When the input occurs, the output is immediately

energized; if the input is then removed, the output remains energized for the adjustable

predetermined time period, then deenergizes. If the input is removed but then reestablished

while the timing holds the output energized, a new output cycle is begun. The LIGHT/

DARK operate jumper wire option is included. Timing range is adjustable from 1.5 to 15

seconds, and op-tional ranges are available.

The 2LM5-14 combines the function of an "on-delay" and an "off-delay" into one logic

module. When the signal is present for more than the output on-delay time, the output

energizes. The off delay circuit is now active, and holds the output on even if the input signal

disappears for short periods of time. If the input signal is gone for longer than the off-delay

time, the output finally drops out. The time delays can control high and low levels in flow

control applications. Each delay is independently adjustable for 1.5 to 15 seconds.

The 2LM5T "limit" timer combines the function of on-off logic and on-delay logic. As long

as the signal is present for only short periods of time, the output "follows the action" of the

input signal. If the input signal is present for longer than the predetermined time, the output

deenergizes. The output only reenergizes when the input signal is removed and then

reestablished. Interval timers are used to operate loads which must not run continuously for

long periods of time, such as intermittent duty solenoids and conveyor motors. Timing

range is adjustable from 1.5 to 15 seconds.
