Standard OMNIBEAM sensor heads feature Banner's exclusive (US patent no. 4965548) D.A.T.A.TM (Display and Trouble Alert) indicator system. The D.A.T.A. system is a built-in 10-element LED array that displays sensing contrast and relative signal strength. When used along with the dedicated alarm output, it warns of impending sensing problems before a failure occurs, thereby preventing expensive down-time. The D.A.T.A. system indicator array is easily visible through a transparent, gasketed sensor head cover. All OMNI-BEAMs offer a choice of prewired cable or quickdisconnect cable fittings. OMNI-BEAM sensors have cross-hole design (with standard limit-switch hole spacing) for back, front, or side mounting, plus a 30mm threaded base mounting hub. An accessory right angle 11-gauge stainless steel adjustable mounting bracket (model SMB30MM) and a VALOX(R) swivel mount bracket (model SMB30SM, page 16) are available. All assembled OMNIBEAM sensors are rated NEMA 1, 2, 3, 3S, 4, 12, and 13. Ordering OMNI-BEAM Sensors OMNI-BEAM sensors are ordered by specifying a sensor head module, a power block module, and an output timing logic module. Modular design, using interchangeable components, allows for use of either ac (105-130V or 210-250V) or dc (10-30V) power blocks plus the easy addition of optional timing logic modules. Standard OMNI-BEAM ac-operated power blocks feature a solidstate ac output relay. DC-operated power blocks feature another Banner exclusive, Bi-ModalTM output circuitry (US patent no. 4982107), for either sinking (NPN) or sourcing (PNP) interface requirements, depending upon the polarity with which the two dc power supply leads are connected. All sensing modes are available, including opposed, retroreflective, diffuse (proximity), convergent, and glass and plastic fiber optic.

(patent #4965548) Sensor Self-diagnostic System Banner's exclusive D.A.T.A. (Display and Trouble Alert) system warns of marginal sensing conditions usually before a sensing failure occurs. This self-checking diagnostic system warns of a problem by flashing one or more lights in a multipleLED array, and by sending a warning signal to the system logic controller (or directly to an audible or visual alarm) by way of the OMNI-BEAM's dedicated alarm output. The D.A.T.A. lights are located on the top of the sensor head and are viewed through a transparent LEXAN(R) cover. The D.A.T.A. lights are configured as follows: 1 Moisture Alert: Severe moisture inside the sensor head, caused by condensation or by entry of moisture when the access cover is removed, will cause the #1 light to flash. 2 High Temperature Alert: When the temperature inside the sensor head exceeds 70C (+158F), the #2 light will flash. 3 Low Voltage or Overload Alert: The number #3 light will flash whenever the sensor supply voltage drops below the minimum that is specified for the power block in use (see power block specifications, pages 12 and 13). Power block outputs are also shut down to prevent damage to the load(s) from low voltage. When using dc power block models OPBT2, OPBT2QD, or OPBT2QDH, the #3 light will flash if either the load output or the alarm output becomes shorted. Both outputs will be inhibited, and the circuit will "retry" the outputs every 1/10 second. The outputs will automatically reset and function normally when the short is corrected. 9 High Gain Warning: The #9 light will flash if the "dark" signal never goes below #4 on the display, and instruct the operator to decrease the gain (see photo above). There are two possible conditions: 1) The High Gain Warning alarm will come "on" if the "dark" signal slowly increases to the #4 level and remains at that level for a predetermined delay time. This condition is commonly caused by an increase (over time) of unwanted background reflections when using reflective sensing modes, such as diffuse (proximity) and convergent beam. The alarm will reset as soon as the cause of the unwanted light signal is removed, or if the GAIN control setting is reduced to bring the "dark" condition below the #4 level. 2) The High Gain Warning alarm will latch "on" if the "dark" signal does not fall below the #4 level during a sensing event. The alarm is automatically reset on any subsequent sensing event in which the "dark" sensing level falls below the #4 level. This is accomplished by reducing the GAIN control setting and/or by removing the cause of the unwanted light return in the "dark" condition. 10 9 + 10 Low Gain Warning: The #10 light will flash if the "light" signal never goes above #5 on the display, and instruct the operator to increase the gain (see photo, above). There are two possible conditions: 1) The Low Gain Warning alarm will come "on" if the light signal slowly decreases to the #5 level and remains at that level for a predetermined delay time. This situation most commonly occurs in opposed or retroreflective sensing systems, and is caused by a decrease in light in the unblocked condition (over time) due to obscured lenses or gradual sensor misalignment. The alarm will reset as soon as the light signal strength exceeds the #5 level. 2) The Low Gain Warning alarm will latch "on" if the light signal does not exceed the #5 level during a sensing event. The alarm is automatically reset by any subsequent sensing event in which the "light" signal exceeds the #5 level. This is accomplished by increasing the GAIN control setting and/or by lens cleaning and sensor realignment. Low Contrast Warning: The #9 and #10 D.A.T.A. lights will flash simultaneously to indicate that there is not enough optical contrast for reliable sensing. This occurs when the "light" condition is at the #5 level and the "dark" condition is at the #4 level for a sensing event. If this warning occurs, the application should be fully re-evaluated to find ways to increase the differential between the "light" and "dark" conditions. The Low Contrast alarm is automatically reset by any subsequent sensing event in which the "light" signal exceeds the #5 level and the "dark" signal falls below the #4 level. SENSE and LOAD Indicator LEDs SENSE The SENSE LED indicates when a target has been sensed. When the sensor head is programmed for LIGHT operate, it lights when the sensor receives enough light to exceed the #5 threshold. When programmed for DARK operate, it lights when the received signal falls below the #5 threshold. The SENSE LED is located at the far left end of the D.A.T.A. array. LOAD The LOAD indicator LED lights whenever the load is energized (after the timing function, if any). The LOAD LED is located at the far right end of the D.A.T.A. array. The SENSE and LOAD indicator LED locations are visible in the photograph above. 5 Standard OMNI-BEAM Sensor Heads Measuring Excess Gain and Contrast The OMNI-BEAM's D.A.T.A. lights may be used to measure the excess gain and contrast in any sensing situation and during installation and maintenance. Excess gain is a measurement of the amount of light energy falling on the receiver of a photoelectric sensor over and above the minimum amount necessary to operate the sensor's amplifier. Excess gain is expressed as a ratio: The amplifier threshold is the point at which the sensor's output switches. The OMNI-BEAM's threshold corresponds to the #5 level of the D.A.T.A. light array. That is, when LEDs #1 through #5 are lit, the excess gain of the received light signal is equal to "1x". The table below (Relationship between Excess Gain and D.A.T.A. System Lights) shows how excess gain relates to the D.A.T.A. light array indication. Excess gain (E.G.) = light energy falling on receiver amplifier threshold Relationship between Excess Gain and D.A.T.A. System Lights D.A.T.A. light LED number #1 #2 #3 #4 #5 STANDARD scale factor 0.25x E.G. 0.35x 0.5x 0.7x 1.0x FINE* scale factor D.A.T.A. light LED number 0.5x E.G. 0.7x 0.8x 0.9x 1.0x #6 #7 #8 #9 #10 STANDARD scale factor 1.3x 1.7x 2.2x 2.9x 3.7x (or more) FINE* scale factor 1.1x 1.2x 1.3x 1.7x 2.2x (or more) *NOTE: the scale factor is selected by programming switch #4 inside the sensor head (see page 7). "OFF" = STANDARD; "ON" = FINE. Use the FINE scale only for setup and monitoring of close-differential sensing applications where LOW hysteresis is required. Contrast is the ratio of the amount of light falling on the receiver in the "light" state as compared to the "dark" state. Contrast is also referred to as "light-to-dark ratio". Optimizing the contrast in any sensing situation will increase the reliability of the sensing system. Contrast may be calculated if excess gain values are known for both the light and dark conditions: Excess gain (light condition) Contrast = Excess gain (dark condition) Contrast Values and Corresponding Guidelines 1.2 or less 1.2 to 2 2 to 3 To determine the contrast for any sensing application, present both the "light" and "dark" conditions to the OMNI-BEAM, and read the D.A.T.A. signal for each. Take the ratio of the two numbers (from the table above) that correspond to the highest D.A.T.A. light numbers registered for the "light" and "dark" conditions. Recommendation Contrast Ratio 3 to 10 10 or greater Unreliable. Evaluate alternative sensing schemes. Poor contrast. Use the LOW hysteresis setting and the FINE scale factor. Low contrast. Sensing environment must remain perfectly clean and all other sensing variables must remain stable. Good contrast. Minor sensing system variables will not affect sensing reliability. Excellent contrast. Sensing should remain reliable as long as the sensing system has enough excess gain for operation. For example, if LEDs #1 through #8 come "on" in the "light" condition and LEDs #1 and #2 come "on" in the "dark" condition (as shown in the photos at right), the contrast (referring to the table at the top of this page) is calculated as follows: Contrast = 2.2x = 6 0.35x This value is expressed as "6:1" or "six-to-one". The best sensor adjustment will cause all ten D.A.T.A. LEDs to come "on" for the "light" condition, and will cause no LEDs to come "on" in the "dark" condition. In this situation (such as an application in which a box breaks a the beam of an opposed mode emitter and receiver): Contrast is greater than 3.7x = 15:1 0.25x 6 DARK condition example: D.A.T.A. system LEDs #1 and #2 lit. LIGHT condition example: D.A.T.A. system LEDs #1 through #8 lit. Of course, it is not always possible to adjust a sensor to maintain this much contrast. However, it is important to always adjust a sensor for the greatest amount of contrast possible for any sensing situation. The D.A.T.A. light system makes this easy. The Contrast Values and Corresponding Guidelines table (above) gives general guidelines for contrast values. Standard OMNI-BEAM Sensor Heads Standard OMNI-BEAM sensor head modules are available in all photoelectric sensing modes: opposed, retroreflective, diffuse (proximity), convergentbeam, and fiber optic (both glass and plastic). They offer the same outstanding optical performance as established by Banner's MULTI-BEAM and MAXIBEAM sensor families. Construction: Standard OMNI-BEAM sensor heads are molded from rugged VALOX(R) thermoplastic polyester for outstanding electrical and mechanical performance in demanding applications. The top view window is LEXAN(R) polycarbonate. Lenses are acrylic. Hardware is stainless steel. When assembled, all parts are fully gasketed. Standard OMNI-BEAM sensor heads are rated NEMA 1, 2, 3, 3S, 4, 12, and 13. Operating Temperature Range: -40 to +70C (-40 to +158F). Delay upon Power-up: 200 milliseconds maximum (power block outputs are non-conducting during this time) Sensor Head Programming Standard OMNI-BEAM sensor heads are field-programmable for four operating parameters. A set of four programming DIP switches is located at the base of the sensor head (see photo at right), and is accessible with the sensor block removed from the power block. Switch #1 selects the amount of sensing hysteresis. Hysteresis is an electronic sensor design consideration which states that the amount of received light signal required to operate the sensor's output is not the same as the amount required to release the output. This differential prevents the sensing output from "buzzing" or "chattering" when a light signal at or near the sensing threshold level is detected. Setting switch #1 to the "on" position programs the sensor head for "normal" hysteresis. The NORMAL setting should be used always, except for lowcontrast situations like the detection of subtle differences in reflectivity. NOTE: the "low" hysteresis setting (switch #1 "off") should be used only when all sensing conditions remain completely stable. Switch #2 selects the alarm output configuration. With switch #2 "on", the alarm output is normally open (i. e., it conducts with an alarm). Turning switch #2 "off" programs the alarm output for normally closed operation (i.e., the output opens during an alarm). The normally closed mode (switch #2 "off") is recommended. This allows a system controller to recognize a sensor power loss or an open sensor output as an alarm condition. The normally open alarm mode (switch #2 "on") should be used when the alarm outputs of multiple Standard OMNI-BEAMs are wired in parallel to a common alarm or alarm input. Switch #3 selects LIGHT operate (switch #3 "off") or DARK operate (switch #3 "on"). In the LIGHT operate mode, the OMNI-BEAM's load output will energize (after a time delay, if timing logic is employed) when the received light level is greater than the sensing threshold (i.e., when five or more D.A.T.A. lights are illuminated). In DARK operate, the output will energize (after a time delay, if any) when the received light level is less than the sensing threshold (i.e., when four or less D.A.T.A. lights are illuminated). For example, when sensing in a beam-break mode like opposed or retroreflective: 1) The DARK operate mode would be used to energize the OMNI-BEAM's output whenever an object is present, and blocking the beam. 2) The LIGHT operate mode would be used to energize the output whenever the beam is unblocked (i.e., object missing). Similarly, when using a reflective sensing mode like diffuse (proximity) or convergent-beam: 1) The LIGHT operate mode would be used to energize the OMNI-BEAM's output whenever an object is present in front of the sensor, reflecting the light beam back to the receiver. 2) The DARK operate mode would be used to energize the output whenever the reflection is lost (i.e., object missing). Switch #4 selects the STANDARD (switch #4 "off") or FINE (switch #4 "on") scale factor for the D.A.T.A. light signal strength indicator array. This switch should always be in the "off" position, except for close differential sensing situations, like some color registration applications, which also require the LOW hysteresis setting (switch #1 "off"). Factory settings: The following are the factory program settings for OMNI-BEAM sensor heads. Switch #1: "on" = normal hysteresis Switch #3: "off" = light operate of load output VALOX (R) and LEXAN(R) are registered trademarks of General Electric Company. Switch #2: "off" = normally closed alarm output Switch #4: "off" = standard scale factor for signal strength meter 7 Standard OMNI-BEAM Sensor Heads Sensing Mode and Models Beam Pattern Excess Gain OPPOSED Mode OSBE & OSBR Range: 150 feet (45m) Beam: infrared, 880nm Response: 2ms Repeatability: 0.01ms Effective Beam: 1" dia.

They are ideal for use when the reflectivity and profile of the object to be detected are sufficient to return a large percentage of emitted light back to the sensor. Model OSBDX is the first choice for diffuse (proximity) mode applications when there is no requirement for less than 15ms response and where there are no background objects to falsely return light.

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 sensor heads, such as model OSBF, 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. 1000 Retroreflective mode, with BRT-3 reflector and BT13S fibers OSBF E X C 100 E S S G A 10 II N OSBF 4 I N 2 C 0 H E S 2 4 with L16F lenses with L9 lenses 6 L16F lens 1 FT with BT13S fibers and BRT-3 reflector L9 lens 6 0 1 .1 FT Retroreflective mode 10 FT 100 FT 4 8 12 16 20 DISTANCE TO REFLECTOR--FEET DISTANCE Diffuse Fiber Optic Mode 1000 The model BT13S fiber optic assembly used with a model L9 or L16F lens and an OMNI-BEAM using a model OSBF sensor head is an excellent system for retroreflective code reading or for almost any short range retroreflective sensing application.

Excess gain 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 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. 1000 I N 2 C 0 H E S 2 IT13S fibers IT13S IT23S 4 6 1 .1 IN 1 IN 0 100 IN 10 IN 10 20 30 40 50 OPPOSED DISTANCE--INCHES DISTANCE 1000 E X C 100 E S S Diffuse Mode OBJECT OSBFX .15 Diffuse mode .1 (Range based on 90% reflectance white test card) G A 10 II N OSBFX I N .05 C H 0 E S .05 BT23S BT13S .1 BT23S .15 BT13S 0 1 .1 IN 1 IN 10 IN 100 IN 1 2 3 4 5 DISTANCE TO 90% WHITE TEST CARD--INCHES DISTANCE VISIBLE-LIGHT FIBER OPTIC Mode (glass fibers) OSBFV Range: see excess gain curves Beam: visible red, 650 Response: 2ms Repeatability: 0.1ms Opposed Mode 1000 OSBFV Model OSBFV is a visible-light version of the model OSBF. It is compatible with Banner individual and bifurcated glass fiber optic assemblies. The visible red light source of the OSBFV increases optical contrast in many sensing situations, which makes it particularly useful for most applications involving diffuse-mode color registration sensing. (An important exception is applications involving red-on-white contrasts, which require a green light source.) The OSBFV is also well suited to presence sensing of translucent materials and registration mark sensing on clear webs in the opposed mode, and for code-reading and/ or short-range or narrow-beam sensing in the retroreflective mode. 1 IN 10 IN IT13S fibers IT23S fibers 3 6 9 12 OPPOSED DISTANCE--INCHES 0 100 IN DISTANCE 15 1000 Retroreflective Mode RETRO TARGET E X C 100 E S S G A 10 II N OBJECT 1 .1 FT OSBFV 6 Retroreflective mode, with BRT-3 reflector 4 with L16F lens and BT13S fibers I N C H E S OSBFV retroreflective mode BT13S fibers 2 with L9 lenses 0 with L16F lenses 2 4 with BRT-3 reflector with L9 lens and BT13S fibers 1 FT 6 0 10 FT 100 FT 4 8 12 16 DISTANCE TO REFLECTOR--FEET 20 DISTANCE 1000 OSBFV E X C 100 E S S Diffuse Mode with BR13S fibers 1 .01 IN diffuse mode .05 Range based on 90% reflectance white test card G A 10 II N OSBFV .075 Diffuse mode OBJECT with BR23S fibers I N .025 C H 0 E S .025 BT13S fibers BT23S fibers .05 .075 0 .1 IN 1 IN DISTANCE 10 Opposed mode 1.5 IT13S fibers, no lenses 1 .1 IN OSBFV 1.0 I N .5 C 0 H E S .5 1.0 IT23S fibers, no lenses G A 10 II N OBJECT 1.5 Opposed mode, with IT23S fibers and L9 lenses E X C 100 E S S 10 IN .2 .4 .6 .8 1.0 DISTANCE TO 90% WHITE TEST CARD--INCHES Standard OMNI-BEAM Sensor Heads Sensing Mode and Models Excess Gain OPPOSED FIBER OPTIC Mode (glass fibers) OSBEF and OSBRF 1000 Range: see excess gain curves Beam: infrared, 880nm Response: 2ms Repeatability: 0.01ms The OSBEF/OSBRF opposed mode infrared fiber optic pair is compatible with Banner glass fiber optics.

CHEMICAL RESISTANCE OF PLASTIC FIBER OPTIC ASSEMBLIES: the acrylic core of the monofilament optical fiber will be damaged by contact with acids, strong bases (alkalis), and solvents. The polyethylene jacket will protect the optical fiber from most chemical environments; however, materials may migrate through the jacket with long-term exposure. Samples of plastic fiber optic material are available from Banner for testing and evaluation. 11 OSBFAC AC-coupled Fiber Optic Sensor Head The OMNI-BEAMTM model OSBFAC is a special-purpose accoupled fiber optic sensor head module. It is intended for applications in which the light signal change is so small that sensitivity adjustment of ordinary dc-coupled sensors is difficult or impossible. The OSBFAC responds to even smaller signal changes than do standard fiber optic OMNI-BEAM sensors set for LOW hysteresis, and is less affected by gradual signal changes due to dirt buildup, etc. Typical applications include thread break detection, web flaw detection, and detection of small parts falling randomly from vibratory feeders or small presses. Model OSBFAC with power block and rectangular fiber optics attached. Many such low-contrast photoelectric sensing applications present problems to dc-coupled sensors because of switching hysteresis. Switching hysteresis is a designed-in property of dc-coupled sensors that causes the "turn-on" point of the sensor's dc-coupled amplifier to be slightly different than the "turn-off" point. Its purpose is to prevent "indecision" and erratic operation of the sensor's output circuit when the light signal is at or near the switching point of the dc-coupled amplifier. The OSBFAC, with its ac-coupled amplifier, reliably amplifies the small signal changes found in many low-contrast sensing applications. An automatic gain control (AGC) feedback system locks onto the light signal and continually adjusts the light intensity of the emitter so that the system is always maintained at exactly the desired reference level regardless of the sensing range or degree of environmental contamination. A multi-turn GAIN control enables setting of the amplifier sensitivity. Typical OSBFAC application The OSBFAC detects small parts falling randomly from a vibratory feeder. Instead of the D.A.T.A.TM array of other OSB Series sensor heads, the OSBFAC has a LOCK indicator LED that lights when the AGC circuit has locked onto the signal, and a LOAD indicator LED that lights whenever the sensor's output circuit is energized. Both LEDs are easily visible beneath the OSBFAC's transparent LEXAN(R) top cover. A slide switch inside the base of the OSBFAC sensor head selects either light- or dark-operate. When light operate is selected, output occurs on a dark-to-light transition. When dark-operate is selected, output occurs on a light-to-dark transition. The OSBFAC requires use of the model OLM8 or OLM8M1 slide-in logic module. Sensor head output is in the form of a quick pulse, and an OLM8 Series module is used to condition this pulse to the desired length. See page 15 for further information on these logic modules. The OSBFAC ac-coupled fiber optic sensor head may be used with any of the following OMNI-BEAM power block models: OPBT2 and OPBT2QD (powered by 10 to 30V dc); OPBA2 and OPBA2QD (powered by 105 to 130V ac); or OPBB2 and OPBB2QD (powered by 210 to 250V ac). See pages 13 and 14 for power block information.

Standard OMNI-BEAM DC Power Blocks Featuring Banner's exclusive Bi-ModalTM output Standard OMNI-BEAM dc power blocks provide regulated low voltage dc power to the sensor head and logic module (if one is used), with input of 10 to 30V dc. There are two infinite-life outputs, one for the load and the other for the alarm of the D.A.T.A. self-diagnostic system. All models, except emitter-only types, have the unique Bi-ModalTM output design (US patent no. 4982107) that offers either sinking (NPN) or sourcing (PNP) outputs, depending upon the polarity with which the two dc supply leads are connected. Outputs are protected from overload, shorted load, or low voltage conditions. Outputs automatically reset when the cause of the problem is cleared. Problems are identified by the D.A.T.A. light system. All standard OMNI-BEAM power blocks are epoxy-encapsulated and rated for -40 to +70C (-40 to +158F). They feature limit switch style cross-hole design for front, back, or side mounting, plus a 30mm threaded hub for swivel bracket or through-hole mounting. Models include prewired cable or either style of quick-disconnect (QD) fitting. Assembled OMNI-BEAM Sensors are rated NEMA 1, 2, 3, 3S, 4, 12, and 13. *NOTE: contact factory for availability of eurofastTM QD models. Specifications, Standard dc Power Blocks Input: 10 to 30V dc at less than 80mA (exclusive of loads), 10% maximum ripple. Output: two identical open-collector transistors, one for load and one for alarm. Both are configured to either sink (NPN) or source (PNP), depending upon the polarity of the power supply leads (see hookup drawings). 100mA maximum continuous, overload and short circuit protected (both outputs). Off-state leakage current less than 100 microamps. NOTES: Interface to TTL logic is not direct (contact factory).

Hookup to a Simple Load, Hookup to PLC Sinking Outputs Standard OMNI-BEAM dc power blocks interface directly to any type of programmable logic controller or computer dc input. The Bi-Modal output of Standard OMNI-BEAM dc power blocks is configured for current sinking (NPN) by connecting the BROWN supply wire to +V dc, and the BLUE wire to dc common. Outputs sink 100mA, maximum. The current sinking configuration (NPN) is shown here. For the current sourcing configuration, simply reverse the polarity to the BROWN and BLUE power supply wires. Hookup to a Simple Load, Hookup of Emitter Sourcing Outputs Standard OMNI-BEAM emitter sensor blocks (models OSBE and OSBEF) simply require supply voltage to operate. Power blocks without output circuitry are available for powering emitters. However, power blocks with output circuitry may also be used to power emitters (output circuitry will go unused). The Bi-Modal output of Standard OMNI-BEAM dc power blocks is configured for current sourcing (PNP) by connecting the BLUE supply wire to +V dc, and the BROWN wire to dc common. Each output sources up to 100mA. NOTE: "dc+" supply voltage to PLC input must be less than or equal to the OMNI-BEAM's supply voltage Hookup is without regard to polarity. 13 Standard OMNI-BEAM AC Power Blocks Standard OMNI-BEAM ac power blocks are available for either 120V ac or 220/240V ac. They provide the regulated low-voltage dc power required to run the circuitry of the sensor head and logic module (if one is used). All models, except emitter-only types, have two solidstate output circuits, one for switching the load and the other for the alarm of the D.A.T.A. selfdiagnostic system. The LOAD output is an isolated 1/2-amp rated infinite-life solid-state relay. The alarm output is also a solid-state relay, rated at 0.2 amps, with one side of the contact tied internally to the "hot" side of the ac supply voltage. Both outputs have very low off-state leakage current for direct interfacing to programmable logic controllers (PLCs). All Standard OMNI-BEAM power blocks are epoxy-encapsulated and rated for -40 to +70C (-40 to +158F). They feature limit-switch style cross-hole design for front, back, or side mounting, plus a 30mm threaded hub for swivel bracket or through-hole mounting. Models include prewired cable or quick-disconnect (QD) fitting. Assembled OMNI-BEAM Sensors are rated NEMA 1, 2, 3, 3S, 4, 12, & 13. Specifications, Standard ac Power Blocks Input: 120V models: 105 to 130V ac, 50/60Hz, 4 watts (excluding load) 220/240V models: 210 to 250V ac, 50/60Hz, 4 watts (excluding load) Load Output: 500mA max. to 25C, derated 1% per C to 70C; 7 amps max. inrush for 1 second or 20 amps max. for one cycle (non-repeating).

Integral standard 5-conductor quick-disconnect cable fitting. Requires cable model MBCC512, sold separately (page 16). Hookup to PLC Standard OMNI-BEAM ac power blocks are designed to directly interface to ac inputs of programmable logic controllers. The ALARM output may either connect to the system logic controller, or directly switch an alarm. If the ALARM outputs of multiple OMNI-BEAMs are paralleled to a single input, then sensor block programming switch #2 must be in the "on" position (for normally open ALARM output) . AC Sensors in Series Hookup of Emitter Standard OMNI-BEAM ac power blocks may be wired together in series with each other for "AND" logic. Standard OMNI-BEAM emitter sensor blocks (models OSBE and OSBEF) simply require supply voltage to operate. The total voltage drop across the series will be the sum of the individual voltage drops across each power block (approx. 3 volts per block). With most loads, 10 or more power blocks may be wired in series. Power blocks without output circuitry are available for powering emitters. However, power blocks with output circuitry may also be used to power emitters (output circuitry will go unused). OMNI-BEAM Logic Modules Standard OMNI-BEAM sensors easily accept the addition of timing logic when needed. Three multiple-function logic modules are available (see photo, upper right). Model OLM5 is programmable for ON-delay, OFF-delay, or ON/OFF-delay timing logic. Models OLM8 and OLM8M1 offer either ONE-SHOT or DELAYED ONE-SHOT functions. Programming of the logic function, the timing range, and the output state is done via a set of four switches located on the logic module. Both logic modules feature 15-turn clutched potentiometers for accurate timing adjustments. The logic module simply slides into the sensor head housing and interconnects without wires (see photo, lower right). Timing adjustments are easily accessible at the top of the sensor head, and are protected by the sensor head's transparent, gasketed LEXAN(R) cover. Assembled sensors are rated NEMA 1, 2, 3, 3S, 4, 12, and 13. Plug-in timing logic modules are available for either delay or pulse timing functions. OMNI-BEAM Logic Module Specifications Operating Temperature: -40 to +70C (-40 to +158F) Timing Adjustments: Two 15-turn clutched potentiometers with brass elements, accessible from outside at top of sensor block, beneath gasketed cover. Timing Repeatability: Plus or minus 2% of timing range (maximum). Assumes conditions Slide in of constant temperature and power supply. Useful Time Range: Useful range is from maximum time down to 10% of maximum all models. When timing potentiometer is set fully counterclockwise, time will be approximately 1% of maximum for models OLM5 and OLM8, and 2% of maximum for model OLM8M1. Response Time: A disabled timing function adds no measurable sensing response time. OLM5 Delay Timer Logic Module Model OLM5 is programmable for ON-DELAY or OFFDELAY or ON/OFF DELAY timing functions. Each delay function may be independently adjusted and separately programmed for either a long or short adjustment range. The logic module slides into the sensor head and interconnects without wires.

NOTE 2: with switches #1 and #2 "off" (no ON-DELAY programmed), ON-DELAY is adjustable from "negligible" up to 100 milliseconds, maximum. NOTE 3: with switches #3 and #4 "off" (no OFF-DELAY programmed), OFF-DELAY is adjustable from "negligible" up to 100 milliseconds, maximum. OLM8 Pulse Timer Logic Module Models OLM8 and OLM8M1 are programmable for either a ONE-SHOT ("single-shot") pulse timer or a DELAYED ONE-SHOT logic timer. DELAY and PULSE times may be independently adjusted and separately programmed for either a long or short adjustment range. OLM8M1 maximum times are 1/10 those of the OLM8. Logic Function and Timing Ranges: models OLM8 and OLM8M1* #1 Switch Positions #3 #4 ONE-SHOT 1 (.1) second max. pulse OFF OFF OFF ----- ONE-SHOT 15 (1.5) seconds max. pulse OFF OFF ON ----- DELAYED ONE-SHOT 1 (.1) second max. delay 1 (.1) second max. pulse ON OFF ----- DELAYED ONE-SHOT 15 (1.5) seconds max. delay 1 (.1) second max. pulse OFF ON OFF ----- DELAYED ONE-SHOT 1 (.1) second max. delay 15 (1.5) seconds max. pulse ON ON ----- DELAYED ONE-SHOT 15 (1.5) seconds max. delay 15 (1.5) second max. pulse OFF ON ON ----- #2 OFF OFF For normally open outputs (outputs conduct during pulse time) OFF NOTE 1: DELAY is nonFor normally closed outputs (outputs open during pulse time) ON retriggerable.

NOTE 3: with switches #1 and #2 "off" (no DELAY programmed), DELAY is adjustable from "negligible" up to 10 (4.5*) milliseconds, maximum. 15 OMNI-BEAM Accessories Quick-disconnect Cables Quick-disconnect cables are available in two styles: minifastTM SJT-type and eurofastTM ST-style* (standard dc power blocks only). They are ideal for use in situations where it is desireable to be able to substitute or replace the sensor and/or cabling. Standard OMNI-BEAM dc power blocks use 4-conductor cables. Standard ac models use cables with 5 conductors. It is impossible to plug either an ac or a dc sensor into the wrong cable. Minifast cables are 12 feet long. Eurofast cables are 15 feet long. All quick-disconnect cables have 22 AWG conductors.
