Instruction Manual

1. Overview

Overview

The A-GAGE™ EZ-ARRAY™ measuring light screen is ideal for such applications as on-the-ﬂy product sizing and proﬁling, edge-guiding and center-guiding, loop tensioning control, hole detection, parts counting, and similar uses (see Figure 1-1).

Emitters and receivers are available with arrays from 150 to 2400 mm (5.9" to 94.5") long. The emitter has a column of infrared light emitting diodes (LEDs) spaced 5 mm apart; their light is collimated and directed toward the receiver, positioned opposite the emitter, which has photodiodes on the same 5 mm pitch. The light from each emitter LED is detected by the corresponding receiver photodiode.

This sophisticated light curtain is capable of detecting opaque cylindrical objects as small as 5 mm in diameter or measuring part edges within 2.5 mm, depending on the scanning method selected (see Section 1.6). The sensing range is 400 mm to 4 m (16" to 13').

The EZ-ARRAY’s two-piece design makes it economical and easy to use. Controller functionality is built into the receiver housing. It can be conﬁgured for many straightforward applications simply by conﬁguring the six-position DIP switch on the front of the receiver (the receiver user interface). For more advanced control, easy-to-use PC interface software is available on the included CD to conﬁgure the sensors using a PC.

Installation is easy, too. The emitter and receiver housings can be side-mounted or end-cap-mounted using the included endcap brackets; longer models also include a center bracket (see Section 3.1).

Beam synchronization is achieved via the 8-conductor sensor cables. Individual LEDs and a 3-digit diagnostic display on the receiver provide ongoing visual sensing status and diagnostic information. Comprehensive data is available to a process controller via a combination of ﬁve outputs: two analog, two discrete, and one Modbus 485-RTU serial.

1.1 System Components

A typical A-GAGE EZ-ARRAY has four components: an emitter and a receiver, each with an integral quick-disconnect (QD) ﬁtting, plus an 8-pin QD cordset for the emitter and for the receiver (see Figure 1-2). For applications that use the Modbus RTU-485 interface, an additional 5-wire cable is used to connect the receiver with a PC or process controller, via the Modbus 485-RTU connection. (A PC used with software version 1.1 for conﬁguration must run on Windows version 1.2, when available, will be compatible with Vista

1.2 Features

Built-in features in the EZ-ARRAY contribute to its ease of use. Many features are available using either the user-friendly receiver interface or the more advanced PC interface.

Built-in diagnostic programming and easy-to-see indicators on the receiver simplify physical alignment and troubleshooting (Figure 1-3); more advanced diagnostics are available via the PC interface.

The receiver has a bright LED that indicates overall sensing status (OK, marginal alignment, and hardware error). Two other LEDs indicate serial communication status. Seven Zone indicators each communicate the blocked / aligned status of oneseventh of the total array. A 3-digit diagnostic display provides further diagnostic information, including number of beams blocked, whether blanking is conﬁgured, and troubleshooting codes.

The emitter has a red LED that signals proper operation (ON when power is applied). See Section 1.4 for more information about indicators and Section 4.5 for display codes and troubleshooting.

The Alignment routine (Section 4.2 or Section 5.6) automatically equalizes the excess gain of each beam for reliable object detection throughout the array. This routine need not be performed again unless the sensing application changes, or if the emitter and/or receiver is moved.

Conﬁgurable beam blanking accommodates machine components and ﬁxtures that must remain in or move through the light screen. Blanking may be set using the receiver interface, the teach wire, or the PC interface.

The EZ-ARRAY light screen provides a wide selection of sensing and output options, including measurement (“scan analysis”) modes and scanning methods that can determine a target object’s location, overall size, total height, or total width, or the number of objects. Scanning may be continuous or controlled by a gate sensor. Up to 15 systems may be networked, via Modbus; see Section 5 and Appendix A.

1.3 Configuration via DIP Switch or PC Interface

Commonly used conﬁguration options can be set up easily via a six-position DIP switch located behind a hinged clear access panel on the front of the receiver.

Access to the DIP switch can be prevented by using the screwon security plate to hold the clear access panel closed or by disabling them via the PC interface.

For more advanced, individualized applications, use the supplied PC interface software program (the “Banner Sensors GUI”; Section 5) to conﬁgure the receiver. The menu-driven program easily accesses the many scanning and output options. After the desired options are selected, the combination of selections can be saved in an .xml ﬁle, stored in the system conﬁguration computer, and recalled as needed. Communication between the

Instruction Manual

Overview

sensors and a PC is accomplished via the serial output and Modbus RTU-485 interface.

The software also provides alignment and diagnostics routines. An Alignment screen displays the individual status of each beam in the light screen, as well as the total number of beams, and totals of beams blocked, made, and blanked. Built-in diagnostics can be used to assess emitter and receiver status.

Outputs

In addition to the serial output (see above), all models have two analog outputs and two discrete outputs.

The analog outputs are either 4–20 mA current or 0–10V voltage, depending on model (see Section 2-1). They may be conﬁgured (via DIP switch or PC interface) for either a positive or negative slope.

Discrete output 1 is always used for measurement; discrete output 2 may be used either for alarm or measurement operation (selectable via DIP switch or PC interface). When the receiver interface is used, discrete output 1 follows the operation of analog output 1 (it conducts when the analog output senses a target is present). When the PC interface is used for conﬁguration, both discrete outputs have full conﬁgurability, including measurement mode, NPN or PNP polarity, and normally open or normally closed operation.

Display Invert

For applications where the sensors must be mounted with the display end at the top (so that the display is not right-reading), the receiver’s diagnostic display can be inverted for easy reading, either by use of the receiver’s remote wire (Section 1.5) or the PC interface.

1.4 Status Indicators

Both the emitter and receiver provide ongoing visual indication of operating and conﬁguration status.

The emitter has a red LED that signals proper operation (ON when power is applied).

into seven equal segments, each of which is represented by one of the seven LEDs. The LED closest to DIP switch S6 (see Figure 4-1) represents the group of optical channels closest to the receiver display (the “bottom” group). The LED closest to DIP switch 1 represents the far segment of channels.

These LEDs illuminate either green or red. When an LED is green, no unblanked beams are obstructed in that segment. When the LED is red, one or more beams in that segment is obstructed.

Three-Digit Display

The 3-digit display has slightly different functions during normal operation, alignment, and gain adjust modes. In normal operation the display indicates current numerical value of the measurement mode for analog output 1. The display also identiﬁes the following activated sensor functions: blanking and locked-out user interface/electronic conﬁguration, as shown in Figure 1-4. (For directions for inverting the display, see Section 1.5 or 5.8.)

During blanking mode, the display reads “n”, followed by the number of blocked beams in the array. During alignment mode, it reads “A”, followed by the number of blocked, unblanked beams; a period follows the A (“A.”) if blanking is conﬁgured.

During gain adjust mode, the display reads “

l” followed by “1” or

“2” to indicate the gain level. (A “1” represents high excess gain, and a “2” represents low contrast.)

If a sensing error occurs, the display reads “c” followed by a number that corresponds to the recommended corrective action (see Section 4.5).

Blanking Indicator

The Blanking indicator will be visible (ON) when the blanking feature is enabled. It appears as a period following the ﬁrst digit of the display.

Electronic Conﬁguration Indicator

The Electronic Conﬁguration indicator is ON when the sensor conﬁguration is deﬁned by the PC interface, and not the DIP switch and push buttons. When electronic conﬁguration is enabled, the DIP switch and push button settings are ignored.

The receiver has a bright Status LED that indicates overall sensing status (OK, marginal alignment, and hardware error). Two other LEDs indicate whether serial communication is active or if there is a communication error. Seven Zone indicators each communicate the blocked/aligned status of one-seventh of the total array. A 3-digit diagnostic display provides further diagnostic information: number of beams blocked, whether blanking is conﬁgured, and troubleshooting codes. See Section

4.5 for display codes and troubleshooting.

Zone Indicators (Beams Blocked Segment)

Seven LEDs represent emitter/receiver alignment status. They provide a visual aid for sensor alignment and monitoring objects within the sensor’s ﬁeld of view. The sensor array is partitioned

1.5 Receiver Gray (Remote Teach) Wire

The receiver gray (remote teach) wire is used to electronically emulate the receiver push button functions (see Section 4.5) via a process controller, to disable the DIP switches for security, or to provide a gate input to initiate sensor scanning. Connect a normally open switch between the receiver’s gray wire and dc common, or connect the gray wire to a digital input (PLC) and pulse the wire as indicated in Figure 1-5.

NOTE: A low level is 0 to 2 volts and a high level is 10 to 30

volts or circuit open. Input impedance is 22kΩ.

Remote TEACH/Gate in the System Conﬁg view of the PC interface Setup screen (Section 5.8) determines the functionality of the receiver gray wire, as follows.

Instruction Manual

Overview

When the gray wire is disabled, the receiver is in continuous scan mode; it begins a new scan immediately after updating the outputs from the previous scan. (Continuous scan is used in most analog output applications and whenever continuous updating of the outputs is acceptable.) The gray wire is always enabled when in DIP switch mode.

• Remote Teach — The gray wire provides the full Remote Teach functionality shown in Figure 1.5.

• Alignment/Sensitivity — This mode is an abbreviated version of Remote Teach. It can perform the alignment and sensitivity adjustment functions, but not the display inversion or DIP switch enable/disable functions.

Gate Mode options can be selected via the PC interface only. The gray wire provides a gate input pulse, typically from a dc device such as an NPN-output photoelectric sensor or a PLC discrete output. Refer to Section 5 for more information.

• Gate – Active High — The receiver scans whenever the gate is pulled high.

• Gate – Active Low — The receiver scans whenever the gate is pulled low.

• Gate – Rising Edge — The receiver scans once for each lowto-high gate transition. (Multiple transitions cannot be faster than the sensor’s response for them to be reliably detected.)

• Gate – Falling Edge — The receiver scans once for each high-to-low gate transition. (Multiple transitions cannot be faster than the sensor’s response for them to be reliably detected.)

1.6 Scanning Method

One of three scanning methods may be conﬁgured:

• Straightscan

• Single-edgescan

• Double-edgescan(1,2,4,8,16,or32steps)

Straight Scan is the default mode, in which all beams are scanned in sequence, from the display end to the far end of the array. This scanning method provides the smallest object detection size. Straight scan is used when low-contrast sensitivity is selected or when single-edge and double-edge scan cannot be used. The edge resolution is 5 mm (0.2"). When low-contrast sensing is selected (used when measuring semitransparent objects), the minimum object detection size is 5 mm (0.2") diameter. When high-excess-gain sensing is selected, the minimum object detection size is 10 mm (0.4"). See Figure 1-5.

Single-Edge Scan is used to measure the height of a single object. This scanning method is commonly used for box height measurement. For single-edge scan, the receiver always activates the ﬁrst beam channel (or “bottom” beam, nearest the display). When the ﬁrst beam is blocked, the sensor performs a binary search to hunt for the last beam blocked, as follows:

1. The receiver scans only the ﬁrst beam until it is blocked (see Figure 1-7).

2. When the ﬁrst beam is blocked, the sensor looks to see whether the middle beam is blocked or made (unblocked).

3. If the middle beam is made (unblocked), the sensor checks the bottom quarter beam; if the middle beam is blocked, the sensor checks the top quarter beam.

4. The routine continues to divide the number of beams in half until the edge is found.

Single-edge scan can be used only for single, solid objects that block the ﬁrst beam (closest to the display). Because the receiver checks only the ﬁrst beam until it is blocked, single-edge scan will not function when the item to be measured does not block the ﬁrst beam. Single-edge scan is also ineffective if the object does not present a continuous blocked pattern.

Single-edge scan works only when the high-excess-gain setting is enabled. When single-edge scan is selected, the sensor object detection size is 10 mm and edge resolution is 2.5 mm.

Sensor response time is a function of sensor length and scanning method. Maximum scan times are shown in Figure 1-6.

Overview

A-GAGE EZ-ARRAY

Instruction Manual

Double-Edge Scan is used to detect two edges of a single object, for example, to determine box width measurements. Double-edge scan requires the selection of a step size: 1, 2, 4, 8, 16 or 32 beams. The sensor uses the steps to “skip” over beams, as follows:

1. The sensor activates beam 1 (closest to the sensor display end).

2. The sensor activates the next beam, determined by the step size. (For example, if the step size is 2, beam 3 is next; if the step size is 8, beam 9 is next.)

3. As long as the activated beam is made (unblocked), the sensor continues the stepping routine until a blocked beam is found.

4. When a blocked beam is found, a binary search is conducted to ﬁnd the object’s “bottom” edge.

Step #1 Step #2 Step #3

Beam #1 of 30 blocked

Beam #15 blocked

5. When the bottom edge is found, the sensor continues to step through the array until it ﬁnds the next unblocked beam.

6. Another binary search is performed to ﬁnd the second edge.

Similar to single-edge scan, double-edge scan has some restrictions: the object should provide a solid obstruction; the size of the object determines the maximum step size (Figure 1-6). Double-edge scan can be used to detect up to three objects. Like single-edge scan, double-edge scan works only when the high-excess-gain setting is selected. When doubleedge scan is selected, the sensor object detection size varies, depending on the step size, but edge resolution is 2.5 mm.

1.7 Gain Configuration

The EZ-ARRAY provides two gain options for straight scan applications: high excess gain and low contrast. The gain method can be selected using the receiver push button, the receiver remote teach wire, or the PC interface.

High (maximized) excess gain is suited for detecting opaque objects and for reliable sensing in dirtier environments where objects to be detected are 10 mm or larger. The high excess gain method is always used in single- and double-edge scan. The high excess gain option has a minimum blocked threshold level, which provides reliable sensing at higher excess gain levels.

The low-contrast setting is used for sensing semi-transparent materials and for detecting objects as small as 5 mm (straight scan only). In low-contrast operation, only a portion of a beam must be blocked for detection to occur. In low-contrast operation, the sensor sets an individual threshold for each optical channel during the alignment process; this process equalizes the signal strength to allow semi-transparent object detection.

When using the PC interface, low-contrast sensing provides a ﬁne-tune sensitivity setting of 15% to 50%. When using the receiver interface, low-contrast sensitivity is always 30%.

1.8 Electronic Alignment Routine

The objective of the optical alignment process is to adjust the emitter light level to maximize sensor performance. Perform the alignment procedure at installation and again whenever the emitter and/or receiver is moved.

During the alignment procedure, the receiver polls each beam channel to measure excess gain and performs a gain adjustment for each beam. When the system exits the alignment procedure, each channel’s signal strength is stored in non-volatile memory.

The procedure can be performed using the receiver remote wire, the receiver interface or the PC interface (see Section 1.5, 4.2, or 5.6). The receiver’s Alignment push button may be disabled, using the PC interface.

1.9 Blanking

If a machine ﬁxture or other equipment blocks one or more sensing beams, the affected beam channels may be blanked. The blanking option causes the receiver to ignore the status of blanked beams for measurement mode calculations. For example, if a machine ﬁxture blocks one or more beams during sensing, the output data will be incorrect; if the beams blocked by the ﬁxture are blanked, the output data will be correct. Blanking may be conﬁgured using the receiver’s Alignment push button, the receiver remote wire, or the PC interface.

“Beam Location” Modes

• First Beam Blocked (FBB): The location of the ﬁrst blocked

beam.

• First Beam Made (FBM): The location of the ﬁrst made

(unblocked) beam.

• Last Beam Blocked (LBB): The location of the last blocked

beam.

• Last Beam Made (LBM): The location of the last made beam.

• Middle Beam Blocked (MBB): The location of the beam midway

between the ﬁrst and last blocked beams.

“Beam Total” Modes

• Total Beams Blocked (TBB): The total number of blocked

beams.

• Total Beams Made (TBM): The number of beams made.

Contiguous Beams Blocked (CBB): The largest number of

•

consecutively blocked beams.

Contiguous Beams Made (CBM): The largest number of

•

consecutively made beams.

For total beam values (TBB and TBM analysis modes), selection of blanked beams affects the proportional analog outputs. Blanked beams are ignored both in the number of blocked or made beams and in the total number of beams. For example, if a 30-beam array has 10 blanked beams and 10 of the remaining 20 beams are blocked, the analog output values will be at mid-range.

1.10 Measurement Mode Selection

The outputs may be conﬁgured for any of fourteen measurement (scan analysis) modes, which refer to speciﬁc beam locations, quantities of beams, or edge transitions. Note that not all measurement mode options are available when the receiver interface is used for conﬁguration. Selected modes are individually assigned to each output (see Section 4.1 or 5.9 and 5.10).

When using the PC interface for conﬁguration, the discrete outputs can have NPN or PNP polarity (regardless of model), be normally open or normally closed, and be assigned to any of the measurement modes. When using the receiver interface, limited output conﬁguration combinations may be selected (Section 4.1).

NOTE: Array beams are numbered in sequence (beam 1 located

nearest the sensor display; see Figure 1-3). The “ﬁrst beam” referenced in the following descriptions is the beam nearest the sensor display.

Overview

• Transitions (TRN): The number of changes from blocked to clear status and from clear to blocked status. (If beams 6-34 are blocked, then there is a clear-to-blocked transition from beam 5 to beam 6, and a blocked-to-clear transition from beam 34 to beam 35.) Transition mode can be used to count objects within the array.

• Outside Dimension (OD): The inclusive distance (measured in beams) from the ﬁrst blocked beam to the last blocked beam.

• Inside Dimension (ID): The number of made beams, between the ﬁrst and last blocked beams.

• Contiguous First Beam Blocked (CFBB): The location of the ﬁrst blocked beam in the largest group of adjacent blocked beams.

• Contiguous Last Beam Blocked (CLBB): The location of the last blocked beam in the largest group of adjacent blocked beams.

• Carpet Nap and Carpet Edge: These measurement modes are used to measure the location of carpet backing and tuft, and are selectable only via the PC interface, and only when the Scan Type “Carpet Nap” is selected. The modes can be measured from either end of the sensor, but at least 10 beams (2") must be blocked from one edge.

• Special: This mode is reserved for specialized applications; contact the factory for information.

1.12 Discrete Output Configuration

Discrete Output 1; Receiver Interface

When the receiver interface is used for conﬁguration, the measurement mode assigned to discrete output 1 is the same as that assigned to analog output 1. When the analog output detects a target present, discrete output 1 conducts (normally open).

Discrete Output 2; Receiver Interface

Discrete output 2 (only) has two options: alarm and complementary (measurement) operation.

Alarm: Output 2 energizes when the receiver detects a sensor error (such as a disconnected cable) or whenever the excess gain of one or more beams becomes marginal.

Complementary (Measurement): Discrete output 2 operation is complementary to discrete output 1 (when output 1 is ON, output 2 is OFF, and vice versa).

Discrete Output 1 and 2 Conﬁguration; PC Interface

When the PC interface is used for conﬁguration, the discrete outputs have more options: either discrete output can be assigned to any of the measurement modes, high and low set points can be added, the outputs can be inverted, and hysteresis values can be set, as well as a scan number to smooth output performance. Discrete output 2 can be assigned to alarm mode via the PC interface also. See Section 5.9 for more information.

1.11 Analog Output Configuration

Analog output conﬁguration assigns analog outputs 1 and 2 to one of the measurement modes described in Section 1.10. When the selected measurement mode involves ﬁrst or last beam blocked or made (unblocked), the assigned output will vary in proportion to the beam number identiﬁed during a scan. When the measurement mode involves total beams blocked or made, that assigned output will vary in proportion to the total beams counted during a scan.

Analog outputs may have Null and Span values set in the PC interface, in addition to a ﬁlter setting (to smooth the output) and Zero Value (to specify the output value when the measurement mode value is zero). See Section 5.8 for more information.

1.13 Serial Communication

When the PC interface is used, the receiver communicates with a process controller via a Modbus RTU-485 interface. The PC interface software has a Communications Settings menu that includes the selected sensor communications port, options (either leave this ﬁeld set at DPB1, or change it to No Echo Suppression), and a read-only window that provides current communications status. Advanced settings are also accessible, including baud rate, timeout (in milliseconds), message delay (in milliseconds), sensor address, parity, retry and byte delay. See Section 5.10 and the Appendix for more information.

Instruction Manual

3.1 Mounting the Emitter and Receiver

Compact EZ-ARRAY emitters and receivers are easy to handle during mounting. When mounted to the sensor end caps, the supplied mounting brackets allow ±30° rotation. An emitter may be separated from 400 mm to 4 m (16" to 13') from its receiver.

From a common point of reference, make measurements to locate the emitter and receiver in the same plane, with their midpoints and display ends directly opposite each other. (If sensors are mounted with their display ends at the top, see Section 1.5 or 5.8 for directions on inverting the 3-digit display.) Mount the brackets to the emitter and receiver housings using the supplied M6 bolts and Keps nuts, or user-supplied hardware; see Figure 3-1.

EZ-ARRAY End-Cap Brackets

(supplied with each emitter and receiver)

End-Mounted

Side-Mounted

(two center brackets may be substituted)

Center mounting brackets must be used with longer sensors, if they are subject to shock or vibration. In such situations, the sensors are designed to be mounted with up to 900 mm unsupported distance (between brackets). Sensors 1050 mm and longer are supplied with a center bracket to be used as needed with the standard end-cap brackets.

1. Attach the center bracket to the mounting surface when mounting the end-cap brackets.

2 Attach the clamp to both slots of the housing, using the

included M5 screws and T-nuts.

3. After the sensor is mounted to the end-cap brackets, attach the clamp to the center bracket using the supplied M5 screw.

3.2 Mechanical Alignment

Mount the emitter and receiver in their brackets and position the windows of the two units directly facing each other. Measure from one or more reference planes (e.g., the building ﬂoor) to the same point(s) on the emitter and receiver to verify their mechanical alignment. Use a carpenter’s level, a plumb bob, or the optional LAT-1-SS Laser Alignment Tool, or check the diagonal distances between the sensors, to achieve mechanical alignment.

When alignment is difﬁcult, a LAT-1-SS tool is useful to assist or conﬁrm alignment by providing a visible red dot along the sensor’s optical axis (see Figure 3-3). Snap the LAT-1 clip onto the sensor housing, turn on its laser emitter, and use a strip of retroreﬂective tape at the opposite sensor to see the dot.

Installation

Also check “by eye” for line-of-sight alignment. Make any necessary ﬁnal mechanical adjustments, and hand-tighten the bracket hardware. See Sections 3.4 and 4.2 for further alignment information.

4. Using the Receiver User Interface

A-GAGE EZ-ARRAY

Instruction Manual

The receiver user interface comprises the six-position DIP switch, two push buttons, 3-digit display, and other indicators present on the receiver (see Section 1.4 for more complete status indicator information). The receiver interface enables conﬁguration of standardized combinations of the EZ-ARRAY sensing options (output conﬁguration, scanning methods and modes); for more advanced setup, refer to Section 5 for PC interface conﬁguration instructions.

4.1 Configuration DIP Switch

The DIP switch can be used to conﬁgure the sensor. Access the switch by removing the screw-on security plate and lifting the clear hinged access cover. The access cover may be removed entirely (pull straight out to remove, press back in to replace) for easier access during conﬁguration.

Some of the switches are assigned their own functions, others work together in combination (see table). Switches S1 and S2 in combination select one of four scanning modes. Switches S3 and S4 in combination select one of four measurement mode pairs (one for each analog output). Switch S5 deﬁnes the analog slope setting for both analog outputs and S6 deﬁnes whether discrete output 2 is complementary to discrete 1, or functions as an alarm (when conﬁguration is accomplished via DIP switch, discrete output 1 conducts when analog output 1 senses the presence of a target).

Scanning Modes (S1 and S2)

Straight Scan (S1 ON, S2 ON) is the most versatile scanning

mode and can be used without the exceptions noted in the other scanning modes. Use this scanning mode when using the low-contrast sensitivity setting to measure semi-transparent materials.

To open access cover, insert a small ﬂat-blade screwdriver, press up, and pull

Figure 4-1. Receiver user interface. NOTE: All DIP switch positions

are shown in the ON condition.

20 P/N 130426 Rev. C

Double-Edge Step 1 (S1 ON, S2 OFF) can be used when

three or fewer opaque objects are presented to the light curtain at one time. The advantage of this mode is improved sensor edge resolution (2.5 mm). The minimum object detection size is 10 mm.

Double-Edge Step 4 (S1 OFF, S2 ON) can be used when three or fewer opaque objects are presented to the light curtain and the minimum size object to be detected is 30 mm. This scanning mode ignores objects smaller than 30 mm. Like Double-Edge Step 1, the sensor edge resolution is 2.5 mm. See Figure 1-8 for sensor scan times.

Single-Edge Scan (S1 OFF, S2 OFF) can be used when a single opaque object is presented to the light curtain at one time. The object must block the “bottom” channel (the channel closest to the receiver display). Like the double-edge scans, the sensor edge resolution is 2.5 mm. The minimum object detection size is 10 mm. See Figure 1-8 for sensor scan times.

Banner Engineering Corp. •Minneapolis, U.S.A.

A-GAGE EZ-ARRAY

Instruction Manual

Receiver Interface

Because single-edge scan is capable only of measuring the height of an opaque object that blocks the bottom channel and all channels up to the height of the object, the pertinent measurement modes are LBB (last beam blocked) or TBB (total beams blocked). When single-edge scan is selected, the selected measurement mode will be applied to both analog outputs. Selection of OD/ID with single-edge scan will result in an error code.

Measurement Modes (S3 and S4)

The measurement modes, determined by switches S3 and S4 in combination, deﬁne what information is calculated by the sensor and sent via the analog outputs. See Section 1.10 for measurement mode deﬁnitions. Discrete output 1 will conduct when analog output 1 detects a target. (If single-edge scan is selected, select measurement mode LBB or TBB.)

During normal operation, the 3-digit diagnostic display reads out the numerical value of the speciﬁed measuring mode for analog output 1.

Analog Slope (S5)

Switch S5 deﬁnes the analog output slope. As the measurement mode values increase, the analog output voltage can either increase (positive slope, S5 ON) or decrease (negative slope, S5 OFF). Switch S5 applies the same slope to both analog outputs.

Complementary / Alarm (S6)

Switch S6 deﬁnes the operation of discrete output 2. When the receiver user interface is used, discrete output 1 is active when an object is detected by the sensor (normally open operation). In complementary mode (S6 ON), output 2 will always be in the opposite state of output 1. In alarm mode (S6 OFF), discrete output 2 will be active when the sensor detects a system fault. System faults include a failed emitter, mis-wiring of the emitter/ receiver communication wire (the pink wire), and low excess gain (if the sensor is conﬁgured for high-contrast sensitivity).

4.2 Alignment / Blanking Button (Electronic Alignment)

The Alignment/Blanking push button is used both to maximize the alignment and to access the blanking feature. The electronic alignment routine adjusts the emitted light level to maximize sensor performance. Perform the procedure at installation and again when the emitter and/or receiver is moved. For PC interface software alignment instructions, see Section 5.5.

Blanking is used to maintain sensing accuracy in applications where a ﬁxed object (for instance a permanently mounted bracket) will block one or more beams. The sensor will ignore the blanked channels when calculating outputs from the selected measurement modes.

Electronic Alignment and Blanking — Receiver Interface

To initiate the electronic alignment procedure, use a small screwdriver to press the Alignment/Blanking button for two or more seconds. The left-hand digit of the 3-digit display will read “A” (representing alignment); the right two digits will show the number of beams blocked. The receiver is learning the clear condition. Rotate the sensors as required (but do not change the distance between them). When the receiver’s 3-digit display shows 0 beams blocked, the sensors are adequately aligned.

Tighten the sensor mounts, then press the Alignment/Blanking button again for two seconds to exit alignment mode. If all sensor light channels are clear, the EZ-ARRAY stores each channel’s signal strength in non-volatile memory and reads “ - - - ” on the 3-digit display. Re-alignment is not required again, unless the emitter or receiver is moved.

If any beams are blocked by objects other than the sensing target to be measured during run mode, those beams can be blanked in alignment mode for more accurate measurement. The blocked beams must be either blanked or cleared during alignment mode for alignment to proceed (see below). While the “A” is visible on the receiver display, momentarily (about 0.5 seconds max.) press the Alignment/Blanking button again. The “A” will change to “n” to indicate the sensor is ready to “learn” the blanking pattern; momentarily press the button again to exit the blanking routine. The sensor blanks the blocked beams and the display changes to “A.”; the period following the lefthand digit signiﬁes blanking is active. Press the Alignment/Blanking button for two seconds to exit alignment mode. The EZ-ARRAY stores each channel’s signal strength in non-volatile memory and reads “

-. - - ” on the 3-digit display to denote blanking is in use.

Flashing “000” on the 3-Digit Display

When returning to run mode, the receiver determines whether any unblanked beam channels are obstructed. If any channels are obstructed, the new alignment settings are not saved; the receiver ﬂashes zeroes on the display three times and sensing will continue, using the previously set alignment settings. If this occurs, either clear the blocked beams and repeat the alignment routine or repeat the alignment routine and blank the blocked beams.

4.3 Gain (Sensitivity Adjust) Button

To change the sensitivity (Gain setting), press and hold the button for two seconds. The left-hand digit of the 3-digit display will read “ or “2” (low-contrast. The sensitivity level can then be toggled between the values 1 and 2. When the desired sensitivity level is displayed, hold the Gain push button for 2 seconds and the sensor will return to run mode.

l”; the right-hand digit will read “1” (high excess-gain)

5.5 Alignment and Blanking

When the Alignment/Status screen is ﬁrst displayed (see Section

5.3 and Figure 5-2), two functions can be performed: Start Sampling and Align Sensor.

The System Alignment screen Channel States display can be used to see an ongoing, realtime display of sensing status. Click on Start Sampling; the Status window will read Sampling in Progress until Stop Sampling is selected. When sampling is not active, the Channel States displays are not updated.

The Channel States status ﬁelds in the screen provide a color-coded, visual status of the number of blocked (red), made (green), and blanked (gray) channels. The selected sensor scan type is displayed in the Scan Type text ﬁeld. The “blanked” value is a count of the beam channels that are ignored when the sensor applies the current blanking conﬁguration to the selected measurement mode (see Section 1.10). The “blocked” value is a count of blocked beams, excluding any blanked beams. The “made” value is a count of unblocked and unblanked beams. The total number of beams blocked, made, and blanked will always equal the total number of sensor beam channels. Below this row of text boxes is a graphic display that depicts the status of each individual beam, color-coded to the totals boxes above it. This graphic display may be used both to view which beams are blocked or blanked and also to blank individual beams.

The Active Measurements status ﬁelds depict the active (selected) measurement modes (up to two), with value for each, plus a history of the minimum and maximum values recorded during the sampling of a target, held until a new target is presented. This sampling tool is useful for setting the sensor discrete output levels, for verifying sensor operation, and for proving out an application.

This applies to blanking conﬁguration information only, not to any other settings.

If any beams are blocked, they must either be cleared or blanked to save the alignment settings (see Figure 5-2).

Click Save & Exit Alignment to save the gain adjustment settings. The sensor will verify that all non-blanked optical channels are clear. If some channels are not clear (fail), the sensor will not perform the electronic alignment process and will retain the previously saved alignment parameters. If all the non-blanked optical channels are clear (succeed), the sensor will save the new electronic alignment parameters. A message will appear that alignment either succeeded or failed.

Figure 5-8. Alignment/Status screen, alignment in progress

5.6 Configuration Setup

Conﬁguration selections other than blanking and alignment adjustment are made to the sensor via the Setup screen. The Setup option becomes accessible after a connection is established between the PC and the sensor, using the Connect option. Refer to Figure 5-12 for an overview of Setup options.

Setup Screen

Selecting Setup (Ctrl + S) from the Sensor menu launches the Setup screen, which has six views: System Conﬁg, Analog Output Conﬁg, Discrete Output Conﬁg, Comm Conﬁg, Part Number and Version Info, and System Diagnostics. The Current View ﬁeld displays the name of the currently selected view and allows quick switching between views; simply click on the arrow at the right side of the ﬁeld to display a drop-down menu of alternate views (see Figure 5-9).

When any Setup view is displayed, the options in the Sensor menu become: READ All (Ctrl + R)

WRITE All (Ctrl + W) Open Conﬁg (Ctrl + O) Recent Conﬁgs (if any exist) Save Conﬁg (Ctrl + S) Close (Ctrl + Q)

Status and Message Windows

On the lower righthand corner of each of the Setup views (Figure 5-10) are two windows, labeled Status and Message. These two windows provide ongoing indication of system status, e.g., Okay, Busy, or Error. In the event of a communication error, a message will appear in the second window, providing further detail about the error.

Verify that the sensor is ON, that cables are connected, and perform a thorough check of the Comm Conﬁg and Options > Communications settings. (The most common communication errors are COM port selection or Timeout.) If this does not correct the problem, refer to Section 5.13 Communications Troubleshooting.

5.7 System Config View

PC Interface

Conﬁguration Type determines whether the Receiver interface or the PC interface will control the sensing parameters.

•DIP Switch: Receiver interface is in control.

•Advanced: PC interface is in control. Select Advanced

to override the receiver DIP switch settings and access conﬁguration settings. (Settings can not be changed unless

Advanced is selected.)

Scan Conﬁguration

•Scan Type. Choose between Straight, Single Edge, or Double Edge Step 1, 2, 4, 8, 16, or 32, or Carpet Nap; see

Section 1.6 for descriptions and scan rates for these scan types. Carpet Nap can be selected only via the advanced conﬁguration and has its own set of parameter options that will appear if it is selected.

•Remote Teach/Gate. This ﬁeld deﬁnes the functionality of the receiver’s gray wire (see Section 1.5).

•Measurement 1 and Measurement 2. These pull-down boxes each select a measurement mode. The measurement mode values will be mapped individually to the analog and/or discrete outputs. The sensor will apply the blocked and clear optical channel status data from each scan to the selected measurement mode(s) to calculate the measurement mode value(s). See Section 1.10.

Gain Conﬁguration

This section is used to deﬁne the sensing sensitivity parameters (see Section 1.7).

Setup screen, System Conﬁg view selections are grouped into four categories: System Conﬁguration, Scan Conﬁguration, Gain Conﬁguration, and User Interface Options. Each category has one or more pull-down boxes of options. Underlined options are the Factory default options. Settings can be changed only when the conﬁguration type is set to Advanced.

Status and Message windows provide indication of

Conﬁguration ﬁelds are not available until Advanced is selected in Conﬁguration Type ﬁeld

• Gain Method: Low-Contrast or High-Excess-Gain operation.

•Low-Contrast Sensitivity is selectable (via the PC interface

only), from 15 percent to 50 percent, when Low-Contrast operation is selected. A 15 percent threshold is used for target objects that attenuate the sensing beam light only slightly. The default low-contrast setting is 30%.

User Interface Options

The user interface options control the Receiver user interface display and push buttons.

•Display Orientation (Normal or Inverted) is used to invert the display to right-reading when sensors are mounted “upside down.” Note that the periods on the three seven-segment indicators do not move when the display is inverted.

•Sensitivity Button ﬁeld (Enabled or Disabled) is used to enable or disable the Sensitivity button for security.

•Align-Blank Button ﬁeld (Enabled or Disabled) is used to enable or disable the Alignment-Blanking button for security.

5.8 Analog Output Config View

This view is used to individually set the parameters for each of the analog outputs. Settings can be changed only when the conﬁguration type (in the System Conﬁg view) is set to Advanced.

• Status determines whether that output is enabled or disabled. When the analog output is disabled, the analog output will source either 0 milliamps or 0 volts.

• Peak Detect Reset (auto or external communication) speciﬁes the method by which the analog output peak-detect is re-triggered. Auto: the analog output remains latched until the sensor array goes clear and then detects another object. External communication: By serially reading the analog latch values (see Appendix A, Example A-8 for an example of peak detect reset using external communication).

Null and Span values can be adjusted to vary the analog signal levels.

These values are factory-calibrated to represent 0 volts

(4 mA) and 10 volts (20 mA). The values represent a 12 bit

number that ranges from 0 to 4095.

NOTE: If reverting a conﬁguration to the default values, ﬁrst

record these factory-calibrated values, so they can later be written to the sensor.

• NULL Output determines the minimum analog output value (must be less than the Span value).

• SPAN Output determines the maximum analog output value (must be higher than the Null value).

5.9 Discrete Output Config View

• Slope selects between positive and negative analog output slope. The slope option allows the analog output to increase as the measurement value increases, or to decrease as the measurement value increases.

• Measurement assigns the desired measurement mode (Meas1 and Meas2, as conﬁgured in the System Conﬁg view) to each output. (Select a negative slope to invert an output.)

• Zero Value is used to specify the analog output value when the array goes clear. The options for Zero Value are hold (output holds the last value before the light screen became clear), minimum (provides the null or minimum value), or maximum (provides the span or maximum value).

• Analog Filter Speed (fast, medium, or slow) allows averaging of the analog output response to slow, and therefore smooth, the response. The analog ﬁlter speed is deﬁned as the number of scans necessary for a step response to reach 95% of the ﬁnal value. These values are as follows:

Response

Speed

Fast 1 scan

• Peak Detect (disabled, minimum or maximum) conﬁgures the sensor to capture a minimum or maximum value and latch this analog value until a reset has occurred (see Peak Detect Reset).

Medium 6 scans

Slow 24 scans

95% Step Response

(sensor scans)

This view is used to individually set the parameters for each of the discrete outputs. Settings can be changed only when the conﬁguration type (in the System Conﬁg view) is set to Advanced.

• Status is used to enable or disable that discrete output.

•Polarity: The discrete outputs are independent and can be

set to either NPN (sinking current) or PNP (sourcing current), regardless of the sensor model.

• Mode selects between normally closed and normally open for each output, in effect, “inverting” the output. When Normally Closed is selected, the output conducts when the sensor scan value is outside of the selected limits. When Normally Open is selected, the output conducts when the sensor scan value is within the selected limits. NOTE: If discrete output 2 Type is selected for Alarm/Health

Status, the options in the Mode ﬁeld become Health or Alarm; see “Type” below.

• Measurement ties the discrete output to one of the two selected measurement modes (Meas1 or Meas2, as conﬁgured in the System Conﬁg view).

• Type (discrete output 2 only) selects between measurement or alarm functions. (Output 1 always is tied to a measurement mode.) If Alarm/Health Status is selected, Output 2 will change state whenever the System detects a sensor error (such as a disconnected cable) or whenever the excess gain of one or more beams becomes marginal, as follows:

Instruction Manual

PC Interface

Health: Output is normally active, becomes inactive when an error occurs. Alarm: Output is normally inactive, becomes active when an error occurs.

• Demodulation is used to smooth the discrete output response. Each discrete output can respond after each sensor scan, or the response time can be increased by increasing the demodulation. Increasing the demodulation increases the required number of consecutive qualifying scans (that have a measurement mode value within the prescribed window and hysteresis values) to change the discrete output state. The maximum demodulation value is 250 scans and is selected independently for each output.

•   Threshold Low and Threshold High Values are used to “window” the measurement values that control a discrete output. The values each identify a beam in the array (beam 1 being closest to the sensor display). At each scan, the sensor processes the status of the optical channels and determines values for the selected measurement modes. For the Discrete Output analysis, the measurement values are compared to the low and high threshold. If the selected measurement value is between the low and high threshold values (including the low and high limit), then the sensor will register a valid condition. After the speciﬁed number of consecutive scan response values (see “Demodulation”), the sensor will recognize that the conditions specifying the discrete output are met and the output will change state.

Hysteresis prevents unstable output conditions when the scan analysis value exactly matches the threshold.

• Hysteresis Low value determines the amount of change that must occur beyond the low threshold to cause that output to change state. The default Hysteresis Low setting is one beam less than the Threshold Low setting.

• Hysteresis High value determines the amount of change that must occur beyond the high threshold to cause that output to change state. The default Hysteresis High setting is one beam more than the Threshold High setting.

5.10 Comm Config View

use the up/down arrows to the left of the ﬁeld. If a new sensor address is selected, update the GUI address via Options > Communications Settings (Ctrl + M) to enable further communication.

• Parity: Select Odd, Even, or None.

• Baud Rate is the data communication rate between the

sensor and the computer used for conﬁguration or the process controller. Choose from three values: 9600, 19200, and 38400.

• Modbus Timeout can be used to relax communication timing. The Modbus standard (Compliant setting) deﬁnes spacing between words within a message to be no longer than the time required to transmit 1.5 bytes of information. However, the time between successive bytes within a serial message can be extended (Extended setting) to allow communication with a slower device.

5.11 Part Number and Version Info View

This view provides basic read-only reference information about the connected emitter and receiver. Information includes the receiver part number, ﬁrmware version numbers, and hardware date codes.

5.12 System Diagnostics View

This view provides read-only information about the connected emitter and receiver, for diagnostic purposes. This information may be useful if factory-assisted troubleshooting is required. Refer to Section 4.6 for possible error codes and corrective action.

• Channel Status ﬁelds display the number of emitter and receiver channels (which should be identical), the location of the ﬁrst bad emitter channel, if any, and the level of optical power being delivered by the emitter.

• Operational Status ﬁelds display the overall Error Code (or System Status), plus the status of each receiver DIP switch position, regardless of whether they are enabled.

• Output Status ﬁelds display the status of each output individually.

• Service Status displays the sensor time of service, updated every two hours.

• Address determines the sensor location (from 1 to 247; default is 65) on the process controller network. Adjust by highlighting the existing number and overtype a new value, or

A.1 Modbus Speciﬁcations and Message Formats

For the latest Modbus protocol and speciﬁcations, please visit

0 up to 252 bytes(s) (High Byte, Low Byte)

The slave address can be assigned a value in the range 1-247. Three function codes are supported: (0x03) Read Holding Registers

(0x04) Read Input Registers (0x10) Write Multiple Holding Registers

The data in the registers is transmitted in big endian order (HIGH byte, LOW byte).

A.1.1 Read Holding Registers (0x03)

This function code is used to read the contents of a contiguous block of EZ-ARRAY holding registers. The command speciﬁes the starting address and the number of registers. The EZARRAY employs a direct addressing scheme. For example, the holding register at address 40001 is accessed by reading address 40001 (0x9C41) directly (i.e. the starting address is not an offset). The register data in the response message are packed as two bytes per register. For each register, the data is returned in a big endian order (HIGH byte, LOW byte).

A.1.2 Read Input Registers (0x04)

This function code is used to read from 1 to 125 contiguous EZ-ARRAY input registers. The command speciﬁes the starting address and the number of registers. The EZ-ARRAY employs a direct addressing scheme. For example, the input register at address 30001 is accessed by reading address 30001 (0x7531) directly (i.e. the starting address is not an offset). The register data in the response message are packed as two bytes per register. For each register, the data is returned in big endian order (HIGH byte, LOW byte).

Instruction Manual

A.2 Modbus Tables

EZ-ARRAY uses the Holding Registers table for providing readwrite access to conﬁguration data. The Holding Registers are deﬁned in the 40000-49999 address range. The Input Registers table is used for providing read-only access to system status and measurement data. The Input Registers are deﬁned in the 30000-39999 address range. EZ-ARRAY employs a direct addressing scheme. For example, the input register at address 30000 is accessed by reading address 30000 (0x7530) directly (i.e., the starting address is not an offset).

Instruction Manual

Glossary

Blanked Beam: A beam that is “ignored” by the receiver, as

a result of a blanking program being applied to it. Beams (or groups of beams) are blanked when a component or ﬁxture will remain in or move through the light screen array; blanking the affected beams prevents the component or ﬁxture from causing false outputs.

Blocked Beam: A beam that is obstructed between the emitter and the receiver, and is not blanked.

Appendix

Clear Beam:

the receiver (same as a made or unblocked beam).

Excess Gain:

on the receiver from the emitter over and above the minimum amount required for operation. A-GAGE EZ-ARRAY emitters and receivers can perform an electronic Alignment procedure to equalize the amount of excess gain at each element along the array.

Host:

receives input from the High-Resolution MINI-ARRAY System, and/or other equipment and systems within a factory.

Made Beam:

the receiver (same as an unblocked or clear beam).

Unblocked Beam: A beam that runs unobstructed from the emitter to the receiver (same as a made or clear beam).

A beam that runs unobstructed from the emitter to

A measurement of the amount of light falling

A computer or process controller that controls and

A beam that runs unobstructed from the emitter to
