Ultrasonics Overview Introduction Senix sensors measure the distance or presence of a target object by sending a sound wave, above the range of hearing, at the object and then measuring the time for the sound echo to return. Knowing the speed of sound, the sensor can determine the distance of the object from the transducer element.

Advantages ! Non-contact

Measures through the air without touching the target object, at relatively large distances.

! Object Ranging Object distance is measured rather than just the presence or proximity.

! Distance Proportional Output The sensors outputs are proportional or affected by the measured target distance.

! High Resolution Precise discrimination of target position.

! Unaffected by Targets Optical Characteristics The sensors operation is not sensitive to ambient light levels, the color of the target, or target is optically transparency/reflectivity.

! Sensitive Detects large and small objects.

Typical Applications

Roll Diameter Measure the size of a roll to control tension or speed, or determine full/empty target.

Loop Control Precisely control the position of material loops, including wires, tubes and webs.

Web Break Rapidly detect a broken web in a printing press or paper machine.

Dimensioning Determine the size of an object for information or to determine its volume or width.

Proximity Determine the presence of objects to count or control their movement.

Sort/Select Sort or select objects based on differences in their physical dimensions.

Level Measurement Measure the level of liquid or solid materials in tanks or bins for inventory or batching.and many more...

Terminology Terms listed here are shown in italics throughout this document.

Analog An electrical output type that varies in proportion to measured distance. Analog output types can be either current loop outputs or voltage outputs.

Analog High Limit The maximum (highest) value of an analog output. For example, the Analog High Limit value for a 4-20 ma. current loop analog output is 20 ma. Computer configurable models allow this value to be user-entered.

Analog Low Limit The minimum (lowest) value of an analog output. For example, the Analog Low Limit value for a 0-10 VDC voltage output is 0 volts. Computer configurable models allow this value to be user-entered.

Analog Window A range of distances between two endpoints, within which the analog output will vary between the analog low limit and analog high limit proportional to measured distance.

Current Loop Output An analog output type that drives an electrical current proportional to measured distance. Senix sensors can provide industry standard 4-20 ma. current loop outputs.

Endpoint One of two end distances representing the outer limits of the analog window.

Ingress Rating An enclosure rating that identifies how susceptible a product is to the entry (ingress) of external objects or liquids.

Measurement Rate The repetitive rate that the sensor measures distance (see response time).

Maximum Range The maximum distance at which the sensor will detect a target and report distance. Computer configurable models allow this value to be user-entered.

Minimum Range The minimum distance at which the sensor will begin to detect a target and report distance. Computer configurable models allow this value to be user-entered.

Operating Window The range of distances between the min range and max range values.

Output Status Indicator An indicator at sensor rear that shows the status of an analog, switch or serial data output. There is a separate output

status indicator for output #1 (black wire) and output #2 (white wire).

RS-232 An electrical interface standard used to transfer information using serial data communications. This is a single ended interface with a specified maximum range of 50 feet (15 meters) that typically supports one device.

RS-485 An electrical interface standard used to transfer information using serial data communications. This is a differential interface with a specified maximum range of 2000 feet (600 meters) that is capable of supporting multiple addressable devices.

Response Time The time required for sensor outputs to respond to measurements (see measurement rate).

Serial Data A method of transferring information using a sequential (serial) on/off pattern to encode the data. Two common industry standards are RS-232 and RS-485.

Setpoint The measured distance at which a switch output turns ON.

Sinking A switch type that sinks current from an external load to ground when turned ON. An ON sinking switch output measures a low voltage.

Sourcing A switch type that sources current from the sensor to the load when turned ON. An ON sourcing switch output measures a high voltage.

Switch An electrical output type that is either ON or OFF. ToughSonic® switches are solid state.

Target Any object or material that reflects ultrasonic energy back to the sensor thus allowing the sensor to measure its distance.

Target Indicator An Indicator at sensor rear that shows the status of a detected target.

Teach A Senix product feature that uses the sensors pushbutton to tell the sensor to store a current target distance measurement into memory and automatically calibrate the output(s).

Ultrasonic A sound wave of a frequency greater than 20,000 Hz, typically above the range of human hearing.

Voltage Output An analog output type that drives an electrical voltage proportional to measured distance. Senix sensors provide industry standard 0-10 and 0-5 VDC outputs.

Mechanical Details

Figure 3 - Mechanical Drawing

The transducer is recessed into the case in the TS-30S2 series. For all series, the distance is measured from the transducer end of the housing, not from the transducer face.

Accessories The following types of accessories are available.

Mounting Brackets Several types are available, providing either fixed or adjustable sensor positions.

Stainless Nuts The sensor is shipped with two plastic 30mm mounting nuts. Stainless nuts are available.

Digital Indicators Digital indicators are available to display distance or level measurements.

Orientation Orient the sensor perpendicular to the target object for best results as shown in Figure 4.

DIRECTIONOF MEASUREMENT

Figure 4 - Sensor Orientation

Ultrasound energy must reflect back to the sensor or the sensor will not detect the target. Curved or spherical objects can make good targets because they generally reflect a portion of the energy back to the sensor. However, a flat surface can be detected at a greater distance than a curved surface. Make sure that other unintended targets are not visible to the sensor or false readings may result. Typical measurement angles of deviation from perpendicular relative to a large flat surface are shown in Figure 5.

Mounting The sensor mounts through a hole approximately 1.2 in. (30.5 mm) in diameter as shown in Figure 6.This hole must be available in a bracket or component provided by the user. Position the sensor in the hole and fasten the sensor to the plate with the two nuts provided. The sensor position can be altered a couple of inches depending on where the nuts are placed on the sensor body. Keep the sensor face a distance of at least the minimum range from the closest target position (see Range MIN specification on page 6).

Figure 6 - Mounting

Applying Power After the sensor is wired as described in Connections & Wiring on page 11, it is activated by applying power. Outputs will then operate as described on page 12 and the rear indicators will operate as described on pages 16 and 18.

Temperature Compensation At room temperature, a change of 10 degrees will result in approximately 1% change in the speed of sound and therefore the same change in the distance between the sensor and each Setpoint (without temperature compensation). If this is an issue in your system you may want to consider turning temperature compensation ON using TEACH.

ToughSonic sensors have a temperature sensor at the rear that can be used for temperature compensation. Temperature compensation can be turned ON and OFF using TEACH. The factory default is OFF.

For best results the temperature at the rear of the sensor should reflect the temperature of the air

between the front of the transducer and the liquid surface.

Temperature compensation is less important if under normal use the temperature environment surrounding the sensor remains fairly constant.

If temperature compensation is used outdoors the temperature sensor should be protected from the sun or heating of the sensor will cause measurement errors.




Detection Area The distance at which a target can be detected depends on the size and shape of the object. The approximate sensing areas for some common targets

are shown in Figure 7. The sensitivity to large flat surfaces is shown in Figure 5.

Table 2 - Cable Connections

Ground (blue wire) The ground wire is common to both the power supply and the output circuits and used as described below.

Cable Shield (bare wire) The cable shield is not terminated inside the sensor. This wire should be terminated to equipment ground near the user equipment, preferably to a single point ground for all equipment.

Power Input (brown wire) Connect a DC power supply to the DC+ (Brown) and GND (Blue) wires shown in Table 2. These colors conform to EU standards. The power supply must be between 15-30 VDC if using an analog output, or 10-30 VDC for all other interfaces. Reversing the power connections will not damage the sensor. When power is applied, the rear LED target indicator will light and the sensor measures as described in Applying Power on page 9.




OUTPUTS (Black and White wires) The sensor has two outputs available on the BLACK and WHITE wires. The type of output connected to each wire depends on the sensor part number as shown in Table 1 on page 7. The outputs are also identified on the sensors rear label.

There are several types of output provided in various combinations:

• Analog voltage output, 010 VDC (or 0-5 VDC using Teach feature 30)

• Analog current loop output, 4-20 ma

• Sinking switch (transistor)

• Sourcing switch (transistor)

Each of these output types is described in following sections. Refer to the Specifications on page 6 for information on the sensor outputs.

OUTPUTS (Yellow and Gray wires) The YELLOW and GRAY are used for data communications and SYNC functions. These functions are mutually exclusive. Data communications functions are described on page 14. Optional SYNC functions as described on page 15.

The following models have serial data outputs on the YELLOW and/or GRAY wires:

• Serial Data RS-232 (output only) Uses GRAY for data output

• Serial Data RS-485 (output only) Uses both GRAY and YELLOW for data outputs

Each of these output types is described in following sections. Refer to the Specifications on page 6 for information on the sensor outputs.

Figure 11 - Voltage Output Wiring

The Voltage Output is a 0 to 10 volt DC signal proportional to the measured distance between the endpoints set by the user. The voltage range can be changed to 0-5 VDC using the TEACH button. The polarity of the output is reversible. If the sensor model has this output (see Table 1 on page 7) it is connected to the WHITE wire and measured relative to GND (BLUE wire). The 0 and 10 volt endpoints can be adjusted anywhere in the sensors range using the TEACH button. The TEACH button adjustments that affect this output are listed in Table 6 on page 25. The sensor will use the default configuration endpoints unless changed by the user. Refer to the Adjustment Sequence on page 26 for instructions on changing the endpoints.

NOTE: Sensor models TS-30Sx-IV have both voltage and current loop outputs. The TEACH button distance adjustments affect both outputs simultaneously, i.e., they are not independently adjustable.

The analog inputs of the User Equipment are either differential (both + and terminals) or single ended (+ terminal and GND). A single ended input is relative to the User Equipments ground.

The Current Loop output is a 4 to 20 ma. current sourcing signal proportional to the measured distance between the endpoints set by the user. The polarity of the output is reversible. If the sensor model has this output (see Table 1 on page 7) it is connected to the BLACK wire. Current flows out of the sensor, through the user equipment and back to the sensor GND (BLUE wire). The 4 and 20 ma. endpoints can be adjusted anywhere in the sensors range using the TEACH button. The TEACH button adjustments that affect this output are listed in Table 6 on page 25. The sensor will use the default configuration endpoints unless changed by the user. Refer to the Adjustment Sequence on page 26 for instructions on changing the endpoints.

Figure 13 - Sinking Switch Output Wiring

The sinking switch is an open collector transistor (solid state switch) that sinks current from an external load to GND when ON as shown in Figure 13. Some sensor models have one and some have two of these output(s) (see Table 1 on page 7), and the output(s) are connected to either or both the BLACK and/or WHITE wires. The switching distance (setpoint) can be adjusted anywhere in the sensors range using the TEACH button, and the polarity is reversible about the setpoint. If the sensor model has two switches each has an independently adjustable setpoint and Polarity. Adjustments that affect this output are listed in Table 6 on page 25. The sensor will use factory default setpoints unless changed by the user. Refer to the Adjustment Sequence on page 26 for instructions on changing the setpoints.

Note: If the Response Time (page 23) filter is set to SLOW there may be a time delay for the switch state to change.

If the sensor does not detect a target within its range the switch(es) will turn OFF either immediately or after 1 second depending on TEACH Feature 20 (see Table 6).

Figure 15 - RS-232 & RS-485 Wiring

The RS-232 and RS-485 output are a serial digital data stream transmitted every 50 mSec. (faster using Teach Features 25-27). Wiring is shown in Figure 15. Sensor models with these outputs are identified in Table 1 on page 7. Only the SLOW/FAST response time TEACH feature (page 23) affects the data in these outputs. These outputs are transmit-only. Specifications are shown in Table 3.

Format ASCII, 9600 baud, 8 data bits, 1 stop bit, no parity

Resolution 0.003384 inches/count (nominal speed of sound 1128 ft./sec)

Output Stream

5-ASCII byte Count Value between 0 and 65535, carriage return terminated

Distance Calculation

Multiply count value of Output Stream by Resolution

Zeros output

Theoretical: distance of sensor face Actual: no target detected in range

Table 3 - Serial Data Specifications

The Output Stream transmitted by the sensor is a count value proportional to measured distance. The count value, multiplied by the Resolution, results in




measured distance. For example, the equivalent distance for a count value of 42387 is: 42387 * 0.003384 = 143.44 inches User equipment must be programmed to convert the ASCII output stream to a numeric value, then either use the count value directly or calculate the distance units by multiplying the count by a distance resolution factor that results in the desired units.

SYNC Connection The SYNC connection allows two or more sensors to operate in near proximity without interference. The SYNC feature is not applicable for models with serial data outputs. For single sensor applications, leave the SYNC wires unconnected.

If two or more sensors are in near proximity the ultrasonic output from one sensor can interfere with another sensors measurements either by direct or reflected ultrasonic cross talk. The symptom of sensor interference is an output (analog or switch) jumping intermittently but somewhat repetitively to a value or state representing a target closer to the sensor than the actual target. This symptom may disappear or be less severe when the output response time (page 23) filter is set to SLOW. If interference is suspected, turn off all but one sensor to determine if the output stabilizes.

To use the SYNC feature, select ONE sensor in a group of 2 or more to be the MASTER using TEACH feature 12. Then, connect the Gray wire of the MASTER sensor to the Yellow wire(s) of all other (SLAVE) sensors. This will cause the master to measure at Phase 1 and all slaves to measure at Phase 2 (see Figure 16).

Figure 16 Default SYNC Timing

The times shown in Figure 16 will be correspondingly faster for higher measurement rates (see Measurement Rate on 23).

There are two possible SLAVE settings A and B. The factory default is SLAVE A, which measures at time φ2. The MASTER sensor will measure at time φ1, which is 25 mSec offset from the SLAVE-A. A sensor is set to SLAVE-A (1) at the factory, (2) using TEACH feature 17 to establish a factory configuration, or (3) using TEACH feature 13.

SLAVES can also be set to operate on φ1 by configuring them as SLAVE-B using TEACH feature 14. When set to SLAVE-B they will measure at the same time as the MASTER.

When a sensor is configured as a MASTER its measurement rate is cut in half from 40 measurements/ second to 20 measurements/second to allow 25 mSec between SYNC phases φ1 and φ2. Each SLAVE sensor will automatically detect an active SYNC input. When an active SYNC input is detected the slave measurement rate will synchronize to the master at 20 measurements per second. If the SYNC input is not active the SLAVE sensor will begin measuring asynchronously at 40 measurements/ second. These periods are affected proportionally if faster measurement rates are selected using TEACH feature 25, 26 or 27.

A synchronized slave sensor will revert to autonomous operation after 500 mSec if the MASTER signal is lost. Under this circumstance (SYNC is detected then lost) the slave will change the target indicator to alternately blink Red and Green as a SYNC LOST warning. Flashing will end when SYNC is reestablished, the TEACH button is pressed or sensor power is cycled off then on.

In a two-sensor installation where interference is a factor, set one sensor to MASTER. The other will operate as slave A as per the default configuration.




Adjustment Sensor Rear Features

Figure 17 Sensor Rear View

The rear sensor controls are shown in Figure 17. There are four control features available:

• The TEACH button is used to make sensor adjustments.

• The target indicator (round) shows the target status. It also indicates an Unlocked condition during adjustment, and serves as the power-on indicator, and blinks RED during TEACH operations.

• The output #1 status indicator (square) shows status of the output connected to the sensors black wire. The type of output and indicator function varies with sensor model.

• The output #2 status indicator (rectangle) shows status of the output connected to the sensors white wire or gray wire (serial data models only). The type of output and indicator function varies with sensor model.

TEACH Button The TEACH button is used to make all sensor adjustments. When this button is pressed and held both the Target indicator will blink RED in response. Adjustments occur by releasing the pushbutton after the indicator blinks a specific number of times. Button usage is described in Teachable Features on page 22.

Target Indicator The target indicator is a 2-color LED that serves the following purposes:

• Power Status

• Target Status

• Unlocked Status

• Sync Lost Warning

Power Status When sensor power is applied the target indicator will light and the sensor will begin measuring. The target indicator will be RED or GREEN, and may be flashing at a slow or fast rate depending on the function being indicated (see Figure 18 and Figure 19).

Unlocked Status The sensor must be unlocked to make adjustments. When unlocked the target indicator will continue to indicate target status except the indicated conditions will be slowly alternating on and off.

Sync Lost Warning If the SYNC feature is used (see SYNC Connection page 15) and a slave sensor acquires then looses the master sensors SYNC signal, the slave will revert to autonomous operation and slowly alternate between RED and GREEN until SYNC is restored.




Target Status The target indicator displays target status as follows:

• GREEN is a normal indication, indicating a target is detected within the sensors range

• SOLID RED indicates no target is detected within the sensors range

• FAST FLASH RED indicates a target closer than the sensors minimum range. As the target moves closer to the sensor face detection may become less reliable.

Output Status Indicators Each sensor model has two outputs, identified as Output #1 and Output #2. Each output has a green output status indicator. The electrical outputs types differ by model number, and the indicator function therefore varies depending on the type of output. Figure 20 summarizes the indicator combinations for all models.

Identification Output #1 Status Indicator

• Square green indicator ( )

• Associated with output connected to the BLACK wire

• Indicates either switch, analog status depending on sensor model

Output #2 Status Indicator

• Rectangular green indicator ( )

• Associated with output connected to the WHITE wire

• Indicates either switch, analog status depending on sensor model

• For serial data models this indicator flashes each time data is transmitted from the sensor

Switch Status Output #1 and/or Output #2 may be a solid state switch for some models (see Figure 20). The indicator will operate as follows for a switch:

• Indicator ON if switch is ON

• Indicator OFF if switch is OFF

• Indicator blinks if switch is overloaded. An overloaded switch goes into a safe shutdown mode when the switch is shorted or over temperature.

Switch outputs may be either sinking (SK) or sourcing (SR) but the indication is the same. A switch is considered ON when it is conducting current. A sourcing switch is therefore ON when the output is driven to the supply voltage (output is a higher voltage). When a sinking switch is ON the

connected output is pulled to ground (output is a lower voltage).

Analog Status Output #1 and/or Output #2 may be an analog signal (voltage or current loop) for some models (see Figure 20). The indicator operates as follows:

• Indicator ON if analog value is anything other than the minimum or maximum.

• Indicator OFF if analog value is at the minimum (0 VDC or 4 ma.)

• Indicator blinks ON-OFF if analog value is at the maximum (5/10 VDC or 20 ma)

In a typical installation the analog output is operating within a user-calibrated range and the normal indication is therefore a continuously ON indicator. An OFF or blinking indicator would then indicate a problem because the sensor is detecting a target outside of the expected (calibrated) distance range.

Data Status For models with data outputs (RS-232 or RS-485) the Output #2 Indicator will flicker each time data is transmitted.

TEACH Indication When using the TEACH features to make sensor adjustments (see page 26) the Target Status Indicator will blink RED to provide operator feedback while the TEACH button is pressed. The user must count these flashes, then release the TEACH button after a specific number of flashes to engage a particular TEACH feature.

Analog Output Status (0-10 VDC and/or 4-20 ma current loop) In normal operation the target indicator operates as shown in Figure 21 for sensors with an analog output. During unlocked or SYNC lost operation the target indicator operates as shown in Figure 18 and Figure 19. Some models with analog outputs also have switch outputs. Switch output indication is described on page 21. Table 1 on page 7 provides a complete list of all models and their outputs.

Figure 21 - Analog Output Indicator Functions

There are two output status indicators. Sensor models with a current loop output have the current loop output status indicated on output status indicator #1 (square green ). Sensor models with a voltage output the voltage output status indicated on output status indicator #2 (rectangular green ). For models with both current loop and voltage outputs (TS-30Sx-IV) both indicators operate simultaneously and identically since they are not independently adjustable. Please note the following about analog status indication:

• Both status indicators are GREEN. An ON status indicator is a normal analog status and indicates that the target is between the two endpoints of the analog window. The adjustable endpoints are set using TEACH Features 4 and 5 (see Table 6 on page 25).

• The two output status indicator examples shown above show an increasing analog slope (top) and decreasing analog slope (bottom). An increasing slope means the output value increases proportional to the measured distance and vice versa.

• A FAST FLASHING output status indicator means that the analog output is at the highest possible value (10 VDC or 20 ma.). That value will occur at the distance equal to the high analog endpoint and all distances extending away from the analog window (whether closer to or farther from the sensor).

• An OFF status indicator means that the analog output is at the lowest possible value (0 VDC or 4 ma.). That value will occur at the distance equal to the low output analog endpoint and at distances extending away from the analog window (whether closer to or farther from the sensor).

• If no target is detected (target indicator is red) the analog output will retain the value associated with the last measured target distance and the output status indicator will continue to display that condition.

• Regardless of the output conditions, both output status indicators will SLOW FLASH to serve as user feedback when the TEACH button is pressed and held.




Switch Output Status (Sinking and/or sourcing) and RS-232 In normal operation the target indicator operates as shown in Figure 22 for sensors with a switch output. Switch outputs may be either sinking or sourcing but the indication is the same. Sensor models with switch outputs may have either 1 or 2 switches. Electrically, switch #1 is connected to the black wire and switch #2 to the white wire. During unlocked or SYNC lost operation the target indicator operates as shown in Figure 18 and Figure 19.

Some models with switch outputs also have analog or serial data outputs. Analog output indication is described on page 20. Serial data output indication is described on page 22. Table 1 on page 7 provides a complete list of all models and their outputs.

Figure 22 - Switch Output Indicator Functions

There are two output status indicators. Sensor models with one or two switch outputs may have a switch on either or both of Output #1 and Output #2. The switch #1output status is indicated on output status indicator #1 (square green ) and switch #2 status indicated on output status indicator #2 (rectangular green ). Please note the following:

• An indicator will light green when the associated switch is ON. An ON switch means is it conducting current, and an OFF switch not. A sinking switch output that is ON will have an output value near ground (0 volts). A sourcing switch output that is ON will have an output value near the power supply voltage.

• The three output status indicator examples shown above demonstrate a switch that is ON at distances closer than the setpoint (ON closer), farther than the setpoint (ON Farther) and a FAULT condition. Teach feature 8 is used to set the distance that switch #1 changes state, and TEACH feature 9 to reverse the state (ON closer vs. ON farther). Teach features 10 and 11 perform the same respective functions for switch #2 (see Table 6 on page 25).

• A FAST FLASHING output status indicator means the switch is in an overload or over temperature condition and is automatically turned OFF for protection. Normal operation will be restored automatically when the overload or over temperature condition is reversed.

• If no target is detected (target indicator is red) a switch output will turn OFF either immediately (or after 1 second if TEACH feature 20 is used to enable the OFF delay).




• Regardless of the output conditions, both output status indicators will SLOW FLASH to serve as user feedback when the TEACH button is pressed and held.

Serial Data Output Status For sensor models with RS-232 or RS-485 serial data outputs the Output #2 status indicator display indicates data transmission from the sensor. The indication is independent of the measured distance.

Some models with data outputs also have switch outputs. Switch output indication is described on page21. Table 1 on page 7 provides a complete list of all models and their outputs.

Regardless of the output conditions, both output status indicators will SLOW FLASH to serve as user feedback when the TEACH button is pressed and held.

Teachable Features Many sensor features can be adjusted using the rear TEACH button and Target Status Indicator. Refer to the Adjustment Sequence on page 26 for instructions on setting these features. They are called teachable because the sensor stores actual target measurements as analog endpoints and switch setpoints. A list of available Teach features is included in Table 6 on page 25, and the recommended adjustment sequence is described in Adjustment Sequence on page 26.

Unlock and Lock The locking feature is provided to prevent accidental changes to the sensors Teach feature settings. The sensor is initially locked and must be unlocked using TEACH Feature 3 before any of the following adjustments can be made. When unlocked the target status indicator continues to operate normally except it flashes on and off slowly to indicate the unlocked

condition (see Figure 18). An unlocked sensor will re-lock:

• When TEACH Feature 3 is used again to perform a manual re-lock

• Automatically 15 minutes after the last use of the TEACH button.

Voltage Range The default range for the voltage output is 0-10 VDC. The voltage range can be toggled between 0-10 VDC and 0-5 VDC using TEACH Feature 30.

Voltage and/or Current Span The voltage and current outputs can be set to operate over a user-determined distances (span) by setting the endpoints. In a sensor model with voltage (0-10 VDC) and/or current loop (4-20 ma) outputs, these signals will vary proportionally with the target distance between any 2 distances in the sensors Range. These distance settings are called endpoints.




The distance of the low (0VDC and 4 ma.) endpoint is adjusted using TEACH Feature 4. The distance of the high (10VDC and 20 ma.) endpoint is adjusted using TEACH Feature 5. The endpoints can be in any distance order, allowing an increasing or decreasing output slope. Adjustment is made easy by pointing the sensor at the actual target then using the TEACH button to memorize that reading. The factory defaults are 0VDC/4 ma. at 10 in. (254 mm) and 10VDC/20 ma. at 40 in. (1016 mm), and can always be reestablished using TEACH Feature 17. Target indicator functions for the analog outputs are shown in Figure 21 on page 20.

Switch Setpoint & Polarity If the sensor model has one or two switch outputs these can be set to turn ON or OFF at specific target distances from the sensor. These distance settings are called setpoints and must be within the sensors range. The setpoint distances are established using TEACH Feature 7 for a switch on Output #1 (BLACK wire) and TEACH Feature 9 for a switch on Output #2 (WHITE wire). The output status indicator functions for the switch outputs are shown in Figure 22 on page 21. Switch output #1 is on the BLACK wire and switch #2 on the WHITE wire.

The polarity of a switch on Output #1 can be changed between ON Closer than the setpoint or On Farther than the setpoint using TEACH Feature 8. Output #2 uses TEACH Feature 10.

The factory default is ON Closer than 12 in (305 mm) for a switch on Output #1 (BLACK wire) and ON Farther than 24 in. (610 mm) for a switch on Output #2 (WHITE wire). Reestablish defaults using Teach Feature 17.

If the sensor does not detect a target within its range the switch(es) will turn OFF either immediately or after 1 second depending on TEACH Feature 20.

Measurement Rate The Measurement Rate is how often the sensor measures the target distance. Most applications do not require changing the Measurement rate. The factory default rate is 40 measurements per second (25 mSec interval). In applications where targets are moving quickly the rate can be increased (interval decreased) using TEACH Features 25, 26 and 27. A special slow measurement rate of 1 measurement per second is available using TEACH feature 28. The rate can be restored to 40 per second using TEACH Feature 24 or 17.

Increasing the measurement rate limits the maximum range of the sensor. The time required for an echo to return from a remote target is determined by the speed of sound. Since sound travels at about 1 mSec per foot (3.3 mSec/meter), a target at 5 feet (1.5 m) results in an echo delay of 10 mSec (the sound has to travel out then back before the echo is detected). As the measurement rate is increased the sensor therefore restricts the maximum range as follows:

Measure Rate (meas./sec)

Maximum Range inches (cm)

500 mSec 168 (427) 40 (Default) 168 (427)

67 96 (244) 100 60 (152) 200 30 (76)

Table 4 - Max Range vs. Measure Rate

When operating at higher measurement rates care must be taken to prevent detection of secondary echoes. The ultrasonic wave can bounce back and forth between two surfaces, e.g., the sensor surface or mounting brackets and the target. This can cause the sensor to detect a secondary echo from a prior measurement cycle as the primary echo of the next measurement cycle, resulting in an unstable output.




Response Time The sensors calculated distance can be set to change at a SLOW or FAST rate of change. This will affect how quickly the sensor outputs will change. In FAST rate the outputs respond with the farthest of every two distance measurements (except for the fastest measurement rate, which responds immediately after each measurement). A no-target value is considered to be farther than any other value. In SLOW rate, the measurement rate remains the same but the measured distance value is restricted by an internal algorithm to a rate of change of about 2 inches/second (5 cm/second).

The output rate of change is also affected by the SLOW/FAST measurement rate selection as shown in the table below.

Response Time Teach

Measure Rate (Hz)

Fast Response

Slow Response

24,17 40 50 mSec 1.2 in./sec (30.5 mm/sec)

25 67 30 mSec 2.0 in./sec (50.8 mm/sec)

26 100 20 mSec 3.0 in./sec (76.2 mm/sec)

27 200 5 mSec 12.0 in./sec (305 mm/sec)

28 1 1000 mSec 0.06 in./sec (1.5 mm/sec)

Table 5 - Response Time vs. Measurement Rate

The response time doubles in SYNC mode because the measurement period is twice as long, e.g., the 50 mSec FAST response time at the 40 Hz measurement rate becomes 100 mSec. The SYNCed response times also double at the higher measurement rates.

The factory default Response Time FAST. The response time can be alternated between SLOW and FAST using TEACH Feature 6.

SYNC Configuration All sensor models except those with serial data outputs have a SYNC feature. If more than one sensor will be used in close proximity the SYNC feature will prevent them from interfering with one

another as described on page 15 using Teach Features 12, 13 and 14.

If the SYNC feature is not needed it can be ignored and the SYNC wires left unconnected.

Notes: 1. The sensor must first be UNLOCKED (3 blinks) before making any of the adjustments shown in this table. The target indicator will indicate the unlocked condition as shown in Figure 18. 2. Whenever a DEFAULT CONFIGURATION is set using the TEACH feature 17, this feature is set to the Factory Default value shown in table column 3. 3. The sensor must be detecting the intended target in range prior to setting this feature. The target may be anywhere in the sensors range. See the target indicator description in Figure 18. 4. When the TEACH button is pressed the Target Status Indicator will blink RED. The TEACH COUNT column shows the number of times the indicator must blink to invoke the listed TEACH feature. Release the TEACH button after the indicated number of blinks. If the TEACH button is released mid-blink, that partial blink included in the total count.

Table 6 - Pushbutton TEACH Features List




Adjustment Sequence The sensor is adjusted by pressing and holding the rear TEACH button while counting the number of rear target indicator blinks. For each feature, press and hold the TEACH button while counting the number of red target indicator blinks listed for that feature. (Note 4 in Table 6). Table 6 describes the available TEACH button adjustments. Refer to the prior section for information about these features.

1. Unlock the sensor The sensor is operational upon power-up but is initially LOCKED from adjustments. It must be first UNLOCKED by pressing and holding the TEACH button for 3 blinks of the Output Indicators then releasing it. The target indicator will then SLOW FLASH between OFF and the normal GREEN, RED or RED BLINKS, continue normal operation, and enable the TEACH features. Note: The sensor will re-lock under the conditions described in Unlock and Lock on page 22. A TEACH feature attempted on a locked sensor is ignored.

2. Set the Voltage Output Range If using the voltage output, the factory default is 0-10 VDC. This can be changed to 0-5 VDC (or back to 0-10 VDC) using TEACH Feature 30. * Be aware that TEACH Feature 17 will reset the Voltage Range to 0-10 VDC.

3. SYNC selection Most applications do not require SYNC selection. It is only required when two or more sensors will be located in close proximity (see page 15). Use TEACH Features 12, 13 and 14 for SYNC selection. * Be aware that TEACH Feature 17 will reset the SYNC to SLAVE A.

4. Set the Measurement Rate Most applications do not require changing the Measurement rate. The default rate is 40 measurements per second (25 mSec interval, 50 mSec Response Time). The rate can be increased (interval decreased) using TEACH Features 25, 26 and 27, or restored to 40 using TEACH Feature 24 (see Measurement Rate on page 23). * Be aware that TEACH Feature 17 will reset the Measurement Rate to 40 per second.

5. Adjust Endpoints and Setpoints Available outputs depend on the sensor model (see Table 1 on page 7), so be sure to understand which outputs are on the BLACK and WHITE wires. To set an analog endpoint or switch setpoint, the sensor must first detect an actual or substitute target at the desired endpoint or setpoint distance. A solid GREEN (locked) or SLOW FLASHING GREEN (unlocked) target status indication means a target is detected within the sensors Range. For analog outputs, use TEACH Features 4 and 5 to calibrate the analog endpoints. The endpoints can be set in any order, and can be set to provide either increasing and decreasing output values. For a switch output on the BLACK wire, use feature 7 to adjust the switch setpoint of Output #1. For a switch output on the WHITE wire, use feature 9 to adjust the switch setpoint of Output #2. It is best to make endpoint or setpoint adjustments with the Response Time set to FAST (see below) so that the results are immediately apparent at the sensor outputs. * Be aware that TEACH Feature 17 will reset all output settings to the default values (see Table 6 on page 25).

6. Adjust Switch Polarities For sensor models with one or two switch outputs the polarity of each switch is adjustable. The two possible polarities are ON CLOSER and ON FARTHER than the setpoint distance. The ON condition means the switch is closed (pulled to ground for a sinking switch or providing the current for a sourcing switch). Use TEACH Feature 8 to reverse the polarity of a switch on Output #1 and TEACH Feature 10 to reverse the polarity of a switch on Output #2. These features will reverse the switch polarities regardless of the target status. * Be aware that TEACH Feature 17 will reset the polarities to their default values.

7. Select the Response Time The sensors response time is initially FAST but can be toggled between FAST and SLOW using TEACH Feature 6. It is not necessary for the sensor to measure a target to change this. It is best to make endpoint or setpoint adjustments with the Response Time set to FAST so that the results are immediately apparent. * Be aware that TEACH Feature 17 will reset the response time to FAST.




8. Turn on Temperature Compensation is desired Temperature compensation is OFF by default. It can be turned ON using TEACH Feature 32 or OFF using TEACH Feature 33. See Temperature Compensation on page 9. * Be aware that TEACH Feature 17 will reset the response time to OFF.

Performance Update Rate The sensor measures distance repetitively at a measurement rate of 40 per second (or faster if configured, see Measurement Rate on page 23). After each two measurements, the outputs are immediately updated if Response Time = FAST, or responds at a slower rate if Response Time = SLOW (see

Response Time on page 23). Refer to the Adjustment Sequence and Table 6 for information.

Target Considerations The target must reflect the ultrasound energy back to the sensor. Sensor performance will be affected by the strength of the echo. Flat surfaces are best when perpendicular to the beam direction. Curved surfaces are useful because they usually reflect some portion of the ultrasound energy back to the sensor. Much of the energy is reflected elsewhere, however, so curved surfaces cannot be detected as far away as flat ones. Low-density materials including foams, cloth and powders may absorb or be transparent to ultrasound. Testing is recommended.

Temperature Effects The most significant factor affecting measurement accuracy is temperature. At room temperature, a change of 10 degrees will result in approximately 1% change in the speed of sound and therefore the same change in the distance output. If this is a factor temperature compensation can be turned on (see Temperature Compensation on page 9).

Precautions • Keep unintended targets from the transducers

field of view. Keep the beam pattern in mind.

• Keep the transducer away from ultrasonic noise sources, such as pressurized air nozzles.

• Do not allow material to build up on the sensor face or sensor performance may be suffer.

Maintenance & Cleaning Dust accumulation on the sensor face can be cleaned by blowing pressurized air across the sensor face. In general, dust does not affect performance unless it totally blocks the sound path. Positioning the sensor facing downward rather than upward will minimize material accumulation. The sensor face can be cleaned with alcohol or window cleaner. DO NOT use solvents such as MEK or acetone.




In Case of Difficulty Basic Checkout 1. Apply Power

With DC power applied to the sensor the target indicator should be ON, and may be GREEN, RED or BLINKING RED. If the target indicator is not ON check the power connections. The sensor will not be damaged by a reverse polarity connection.

2. Set Default configuration If you are unsure of the sensors settings, reestablish the Default configuration: • UNLOCK the sensor (see Table 6, 3 blinks)

if not already unlocked • Set a DEFAULT CONFIG (17 blinks)

3. Point the sensor into open space with clearance beyond the maximum Range. The target indicator should display continuous RED (no target). NOTE: Solid RED may also appear in closer spaces if no good target echo is detected.

4. If Output #1 or Output #2 is an analog signal, point the sensor at a target between 10 and 40 inches away . The corresponding Output Status Indicator should be ON within this range, OFF when closer and flashing when farther. When viewed on a meter, the analog output should vary from 0-10 VDC or 4-20 ma. when a target moves between these distances. • 0-10 VDC with VOLT meter connected + to

WHITE wire and to GND) • 4-20 ma. with CURRENT meter connected

+ to BLACK wire and to the GND wire. 5. If Output #1 is a switch output, point the sensor

at a target 12 inches away. The Output #1 status indicator should be GREEN when the target is less than that distance and OFF if greater. The switch output should be ON when GREEN and OFF when the indicator is OFF. Switches turn OFF after 1 second without a target unless the delay is disabled using TEACH 20.

6. If Output #2 is a switch output, point the sensor at a target 24 inches away. The Output #1 status indicator should be GREEN when the target is less than that distance and OFF if greater. The switch output should be ON when GREEN and OFF when the indicator is OFF. Switches turn OFF after 1 second without a target unless the delay is disabled using TEACH 20.

Move the target toward the sensor until it is slightly less than minimum range (4 inches for TS-30S1 series, 1.75 inches for TS-30S2 series). The target indicator should display a SLOW BLINKING RED as you enter this region but may be unreliable when brought closer.
