## WARNING: 

- Do not use this device for personnel protection 

- Using this device for personnel protection could result in serious injury or death. 

- This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A device failure or malfunction can cause either an energized (on) or de-energized (off) output condition. 

## Models 

In the table 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. 

|Model|Function|Description of Logic|
|---|---|---|
|LM1|**OUTPUT**<br>**SIGNAL**<br>**on-off**<br>~~hh~~<br>~~So le 6~~|LM1 is an on-off logic modules that causes the power block output to follow the action of the scanner block:<br>when the scanner block sees a LIGHT signal, the output is energized; when the scanner block sees a DARK<br>signal, the output is de-energized. This is LIGHT operate mode. If the application calls for DARK operate mode,<br>the LM1 may be used with normally-closed power blocks, such as PBAQ or PBT2.|
|LM2|**alternate action**<br>**OUTPUT**<br>**SIGNAL**<br>~~a:~~<br>~~-_)6hS~~<br>~~lr~~<br>~~tm~~<br>~~mm~~|The LM2 provides flip-flop or toggling action of the power block output, such that each time the scanner block<br>changes from a DARK state to a LIGHT state, the output changes state. The output remains in the last state until<br>another change occurs. Some example applications for the LM2 are:<br>•<br>Operating a diverter gate that splits a production line into two lines<br>•<br>Operating room lighting by breaking a photoelectric beam<br>◦<br>If the lights are OFF, breaking the beam turns them ON<br>◦<br>If the lights are ON, breaking the beam turns them OFF|
|LM3|**OUTPUT**<br>**SIGNAL**<br>**on-off**<br>~~hl~~<br>~~So le 6a~~|The LM3 is an on-off logic module that has the ability to be programmed for either LIGHT operate or DARK<br>operate. It comes with a jumper wire installed: with the jumper in place, the output is DARK operated; with the<br>jumper removed, the output is LIGHT operated. The LM3 is the most commonly used logic module when no<br>timing function is desired, particularly if it is not known at the time of ordering which operate mode (LIGHT or<br>DARK) will be needed.|
|LM4-2|**one-shot (retriggerable)**<br>**OUTPUT**<br>**SIGNAL**<br>**HOLD**<br>**HOLD**<br>**Setable time range: 0.1 to 1 second.**<br>~~[—~~<br>~~<— >|~~<br>~~:_—~~<br>~~§€6§56'f~~|The LM4-2 provides a one-shot (or single-shot) output pulse each time there is a transition from LIGHT to DARK<br>(jumper installed) or from DARK to LIGHT (jumper removed). The output pulse time range is from 0.01 seconds<br>to 1 second. The duration of the pulse is independent of the duration of the input signal. The timing of the LM4-2<br>restarts each time that the input signal is removed and then reapplied. This is a retriggerable one shot. This<br>feature may be applied to some rate sensing applications (use LM6-1 for true rate sensing).|
|LM4-2NR|**one-shot (non-retriggerable)**<br>**OUTPUT**<br>**SIGNAL**<br>**HOLD**<br>**HOLD**<br>**Setable time range: 0.1 to 1 second.**<br>~~—~~<br>~~— >|~~<br>~~_—~~<br>~~£é iF~~|The LM4-2NR provides a one-shot (or single shot) output pulse each time there is a transition from LIGHT to<br>DARK (jumper installed) or from DARK to LIGHT (jumper removed). The output pulse time range is from 0.01<br>seconds to 1 second. The duration of the pulse is independent of the duration of the input signal. The output<br>pulse of the LM4-2NR must complete before it recognizes another input transition. This is called a non-<br>retriggerable one shot, which sometimes offers an advantage in indexing or registration control applications<br>where multiple input signals are possible during advance of the product.|

MULTI-BEAM[®] 3- and 4-wire Logic Module 

|Model||Function|Function|Function|Description of Logic|
|---|---|---|---|---|---|
|LM5|**Setab**<br>**OUTPUT**<br>**SIGNAL**|**on-delay**<br>**le time range: 1.5 to 15 seconds.**<br><br>**DELAY**|||The LM5 is a true on-delay logic module. The input signal must be present for a predetermined length of time<br>before the output is energized. The output then remains energized until the input signal is removed. If the input<br>signal is not present for the predetermined time period, no output occurs. If the input signal is removed<br>momentarily, and then reestablished, the timing function starts over again from the beginning. A LIGHT/DARK<br>operate selection jumper wire is included. The standard time range is 0.15 seconds to 15 seconds (feld<br>adjustable), and other ranges are available. The LM5 is often used to detect jams on a conveyor line, where a<br>beam broken for longer than a preset period of time implies a product jammed in the light beam.|
|LM5R|**Setab**<br>**OUTPUT**<br>**SIGNAL**|**off-delay**<br>**le time range: 1.5 to 15 seconds.**<br><br>**HOLD**<br>**HOLD**|||The LM5R is an off-delay logic module, similar to the LM5, except that timing begins on the trailing edge of the<br>input signal. When the input occurs, the output is immediately energized; if the input is then removed, the output<br>remains energized for the adjustable predetermined time period, then de-energizes. If the input is removed but<br>then re-established while the timing is holding the output energized, a new output cycle is begun. The LM5R can<br>be used to tell when no products have broken a beam for a predetermined length of time, therefore indicating a<br>jam or an empty reservoir upstream. A LIGHT/DARK operate selection jumper wire is included. Timing range is<br>0.15 seconds to 15 seconds, and optional ranges are available.|
|LM5-14|**OUTPUT**<br>**SIGNAL**<br>**Setab**|**on- & off-delay**<br>**HOLD**<br>**DELAY**<br>**le time range: 1.5 to 15 seconds.**|||The LM5-14 combines the function of an on-delay and an off-delay into one logic module. When the signal is<br>present for more than the on-delay time, the output energizes. The off-delay circuit is now active, and holds the<br>output on even if the input signal disappears for short periods of time. If the input signal is gone for longer than<br>the off-delay time, the output fnally drops out. The most common use for the LM5-14 is to control fll level, for<br>example in a bin: when the bin is full, a beam is broken, and a predetermined time later, the fow is stopped.<br>After the level has fallen below the beam for a time, the fow is restarted. The time delays control the high and<br>low levels. Each delay is independently adjustable for 0.15 seconds to 15 seconds.|
|||||||
|||**le time range: 1.5 to**||||
|LM5T|**Seta**<br>**OUTPUT**<br>**SIGNAL**|**limit timer**<br>**ble time range: 1.5 to 15 seconds.**<br>**HOLD**|||The LM5T limit timer combines the function of on-off logic and on-delay logic. As long as the signal is present<br>for only short periods of time, the output follows the action of the input signal. If the input signal is present for<br>longer than the predetermined time, the output de-energizes. The output only re-energizes when the input signal<br>is removed and then reestablished. Interval timers are used to operate loads which must not run continuously for<br>long periods of time, such as intermittent duty solenoids and conveyor motors. The LM5T may be used to run a<br>supermarket checkout conveyor, always bringing the product up to the scanner beam and then stopping the<br>motor. When the last item is removed, the motor times out and stops. Timing range is 0.15 seconds to 15<br>seconds.|
|||||||
|||**ble time range: 1.5 to**||||
|LM6-1|**Setable**<br>**OUTPUT**<br>**SIGNAL**|**rate sensor**<br>**rate: 60 to 1200 pulses per minute.**|||The LM6-1 is a true overspeed or underspeed sensing logic module that monitors signals from a scanner block<br>and continuously calculates the time between input signals, and compares that time with the reference set by<br>the HOLD potentiometer. A jumper allows the mode to be changed from overspeed (jumper installed) to<br>underspeed (jumper removed).<br>In the overspeed mode, the output will drop if the preset rate is exceeded.<br>In the underspeed mode, the output remains energized until the input rate drops below the preset. The output<br>will not pulse at low speeds, as retriggerable one-shots do. A DELAY adjustment allows the LM6-1 to ignore<br>data for the frst several seconds after power is applied, to permit the rate to accelerate to operating speed<br>without false underspeed outputs. The sensing rate may be adjusted from 60 pulses to 1200 pulses per minute<br>(0.05 seconds to 1 second per pulse), and the power-up inhibit from 1 second to 15 seconds.|
|LM8|**Setab**<br>**OUTPUT**<br>**SIGNAL**<br>**DELAY**|**repeat cycler**<br>**le time range: 1.5 to 15 seconds.**<br>**HOLD**|||The LM8 is a repeat cycle timing module with independently adjustable delay and hold times. When an input<br>signal is received from the scanner block, a delay period begins during which there is no output. If the signal<br>remains, the delay period is followed by a hold period, during which the output is energized. If the signal still<br>remains, the hold period times out, releasing the output and starting a new delay period. This sequence<br>continues indefnitely until the input signal is removed. The LM8 is used in edgeguide and other registration<br>control schemes where it is desired to pulse the correction motor to avoid overcorrection that might occur with a<br>continuous output. Both time ranges are independently adjustable from 0.15 seconds to 15 seconds.<br>Note:Use of the LIGHT/DARK operate jumper is reversed: remove for DARK, leave<br>in place for LIGHT.|
|LM8-1|<br>**Seta**<br>**OUTPUT**<br>**SIGNAL**|**delayed one-shot**<br>**ble time range: 1.5 to 15 seconds.**<br>**HOLD**<br>**HOLD**<br>**DELAY**<br>**DELAY**|||The LM8-1 is a delayed one-shot that functions like two individual one-shots, with the end of the frst initiating<br>the second. When an input signal occurs, a delay period is initiated, during which time the output is not<br>energized. After the delay, the output is energized for the hold period, then de-energized. No further action takes<br>place unless the signal is removed and then reestablished. This sequence is independent of the duration of the<br>input signal. The LM8-1 is frequently used to sense a product, and then act on that product a short time later<br>when it is clear of the inspection station. An example might be to inspect cartons for open faps, and to eject the<br>faulty cartons when they have completely passed the inspection point. Both time ranges are adjustable from<br>0.15 seconds to 15 seconds.|

## Overview 

A Banner MULTI-BEAM Sensor is a compact modular self-contained photoelectric switch consisting of three components: a scanner block, a power block, and a logic module. 

The scanner block comprises the housing for the sensor and contains a complete modulated photoelectric amplifier, the emitter and receiver optoelements and lenses, and space for the other modules. 

The power block module provides the interface between the scanner block and the external circuit. It contains a power supply for the MULTI-BEAM plus a switching device (except in emitter-only power blocks) to interface the sensor to 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 opposed mode emitter/receiver pairs do not require a logic module. Emitter scanner blocks are supplied with a bladepin to interconnect the scanner block and power block. Power block and logic modules are purchased separately. This modular design, with fieldreplaceable power block and logic modules, permits a large variety of sensor configurations, resulting in exactly the right sensor for any photoelectric application. 

## 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. All MULTI-BEAM 3- and 4-wire logic modules are color-coded red, and are for use only in MULTI-BEAM 3- and 4-wire sensors. The time ranges specified for the logic modules are standard time ranges. For additional time ranges, see Modifications on page 3.

## Modifications 

The time ranges of any MULTI-BEAM 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. 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. 

|Model Number Suffix|Setable Time Range|
|---|---|
|M.01|0.001 seconds to 0.01 seconds|

- For logic modules with a single timing function , specify the maximum desired time in seconds (for example, LM5M5 indicates an LM5 ondelay 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 (for example, 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 fxed timing , the letter F should always be followed by the desired time, in seconds (for example, 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, LM5MF.01, etc.
