WARNING . . .

Not To Be Used for Personnel Protection

Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.

These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current Banner Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection.

OMNI-BEAM Features

• Sensor heads feature Banner’s D.A.T.A.™ (Display And Trouble Alert) indicator system* which warns of an impending sensing problem before a failure occurs

• 10-element LED array displays sensing contrast and received signal strength and warns of a sensing problem due to any of the following causes:

- Severe condensation or moisture

- High temperature

- Low supply voltage

- Output overload (dc operation)

- Too much sensing gain

- Not enough sensing gain

- Low optical contrast

• Separate indicators for target sensed and output energized

• Sensor heads are field-programmable for the following response parameters:

- Sensing hysteresis

- Signal strength indicator scale factor

- Light or dark operate of the load output

- Normally open or closed alarm output

• Choose power blocks for high-voltage ac or low-voltage (10 to 30V) dc operation

• Sensor head and power block plug (and bolt) together quickly and easily

• Optional plug-in output timing modules may be added at any time

OMNI-BEAM Overview

Modular Design

OMNI-BEAM is a modular self-contained sensor. It is made up of a sensor head and a power block; an optional plug-in timing logic module may be added easily. The three modular components, sold separately, simply plug and bolt together — without interwiring — to create a complete self-contained photoelectric sensor tailored to a particular application’s exact sensing requirements.

The sensor lenses and modular components are all field-replaceable. OMNI-BEAM’s modular design makes change-out of any component quick and easy.

Sensor Heads

A sensor head module is available for every sensing situation. Sensor heads bolt directly onto the power block, and are fully gasketed for protection against environmental elements. The D.A.T.A. self-diagnostic feature is standard on all OMNIBEAM sensor heads (except emitters and model OSBFAC). Select from most sensing modes, with infrared or visible red, green or blue sensing beams available.

OMNI-BEAM Power Blocks

Power Blocks

The power block determines the sensor operating voltage and also the sensor output switch configuration. Models are available with a built-in 2 m (6.5') or 9 m (30') cable, or with either Mini-style or Euro-style quick-disconnect (“QD”) plug-in cable fittings. Emitter power blocks have no output circuitry.

Optional Timing Logic Modules

Timing logic may be added at any time, using one of three timing delay and pulse logic modules. Installation is simple and quick; the logic modules simply slide into the sensor head (see Figure 4). Program them for timing functions and ranges via four DIP switches; each module includes easily accessible 15-turn clutched potentiometers for accurate timing adjustments.

Sensor Head Programming

DIP Switch Settings

OMNI-BEAM sensor heads are field-programmable for four operating parameters. To access the four programming DIP switches (see figure 5), remove the sensor block from the power block.

Switch #1, Sensing Hysteresis ON: Standard hysteresis. OFF: Low hysteresis; should be used only when all sensing conditions remain

completely stable.

Hysteresis is an electronic sensor requirement that the amount of received light needed to energize the sensor’s output not be equal to the amount needed to release the output. This differential prevents the sensing output from “buzzing” or “chattering” when the received light signal is at or near the sensing threshold level. The standard setting should be used always, except for low-contrast applications such as the detection of subtle differences in reflectivity.

Switch #2, Alarm Output Configuration ON: Alarm output is normally open (it conducts with an alarm). OFF: Alarm output is normally closed (the output opens during an alarm).

Normally closed mode (OFF) is recommended; it allows a system controller to recognize a sensor power loss or an open sensor output as an alarm condition. Normally open alarm mode (ON) should be used when the alarm outputs of multiple OMNI-BEAMs are wired in parallel to a common alarm or alarm input.

Switch #3, Light or Dark Operate ON: Dark Operate mode; the output energizes (after a time delay, if applicable) when

the received light level is less than the sensing threshold (4 or fewer D.A.T.A. lights ON).

OFF: Light Operate mode; the sensor’s load output energizes (after a time delay, if

applicable) when the received light level is greater than the sensing threshold (5 or more D.A.T.A. lights ON).

Switch #4, Scale Factor for the D.A.T.A. Signal Strength Indicator Display ON: Fine scale. OFF: Standard scale.

This switch should always be OFF, except for close differential sensing situations (for example, 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 head DIP switches.

Switch #1: ON (Standard hysteresis) Switch #2: OFF (Normally Closed alarm output) Switch #3: OFF (Light Operate load output) Switch #4: OFF (Standard Scale Factor for signal strength display)
