Getting Started

Introduction

The Optical Rotary Torque Transducer provides a method of precisely measuring bi-directional rotary or static torque. It can also be fitted with a speed sensor for monitoring in dynamic applications, enabling direct measurements of transmitted power.

The ORT series transducers require no external instrumentation and has its own built in test capability. Its compact size makes it ideal for use in applications where there is little space for any extra equipment. Analog voltage outputs are standard, with current outputs available as an option. The ORT240 series can also be connected to a PC via USB (optional) or RS232 so that its configuration can be changed, or by using TorqView to display torque, speed and power.

CAUTION

The ORT series transducers should not be operated at any torque load greater or speed faster than that specified in the Product data sheet and on the Transducer.

CAUTION

The ORT series transducers should be installed using correct couplings rated for

the maximum torque and speed for the operation.

CAUTION

The ORT series transducers should not be operated in an environment where that

operation could be life threatening or a danger to personnel.

CAUTION

In electrically noisy environments, the ORT series transducers should be earthed

using the earthing post located on the transducer.

 Sensor Technology 2016 Page 4 ORT4076IM (Rev 1)

Mechanical Installation

To obtain the best measurements from your torque transducer it is essential that it is correctly installed.

To avoid damaging the transducer during the installation process it is highly recommended that it is electrically connected and working so that any torque overloads applied due to handling can be monitored.

For Transducers above 1Nm or 10lbf.in. it is recommended that the body of the

transducer is restrained from rotation using a strap or straps connected to the tapped holes in the end plates and that it is not rigidly mounted. Couplings should be used to allow for angular misalignment while the transducer shaft takes up any parallel misalignment. Care should be taken not to induce any end loads or bending moments to the shaft, see below, as these may induce inaccuracies to the torque measurement and in extreme cases damage the transducer.

Should rapid variations in torque need to be measured in detail e.g. torque fluctuations in gearboxes or multi vane pumps then it is recommended using torsionally rigid couplings fitted at both ends of the transducer shaft such as single membrane couplings and that

these are correctly selected for the transducer rating and speed.

An undersized coupling will not transmit the torque while the high inertia of an oversized coupling can result in instantaneous peak torques far in excess of the measured torque. Alternatively, for lower bandwidth applications where it is more important to measure the ‘average’ torque rather than fast torque fluctuations then couplings with a degree of compliance would be more appropriate.

Never use a solid coupling to connect a ORT series transducers Torque Transducer

For Transducers below 1Nm or 10lbf.in or if the application

requires the body to be rigidly mounted then it is recommended that double couplings should be used at each end to compensate for any misalignment of the input/output shafts and the system designed to eliminate any end loads on the transducer shaft. For applications

where end loads cannot be avoided please consult the sales department for advice prior to ordering.

When using a pulley or pulleys it is recommended a bearing block or blocks should be used to ensure bending loads are not transmitted to the transducer.

Lastly, consider using a guard over the transducer and couplings

Whilst the transducer is resistant to EMC interference to BS EN 61326-1:2006, the sensible routing of cables is important to avoid possible EMC interference. Avoid running the transducer cables close, and/or parallel, to high voltage cables, solenoid valves, generators or inverters etc. If the cables must follow the same route as interfering cables then additional screening such as metal conduit should be used to provide isolation.

To avoid damaging the transducer during installation it is highly recommended that it is electrically connected and working during this process so that any torque overloads due to handling can be monitored.

Operating Principles

The shaft of the transducer should be connected to the mechanical system on which the measurements are to be made using appropriate couplings so it can rotate freely up to its maximum recommended speed, with relation to the transducers body and bearings fitted.

The technology for our Optical ORT230/240 Series Torque Transducers is based on an extensively proven and developed measurement principle whereby two discs with segmented gratings are positioned on the shaft so that the opaque sectors on one disc partially obscure the clear sectors on the other. Light passes through the sectors and is detected by photovoltaic detectors. The intensity of light beams, which is constantly monitored, is modulated by the applied torque and produces an electrical output that is used to provide a precise indication of the torque transmitted by the shaft. The light intensity is automatically controlled within the transducer body by a monitor cell. Lamps used to provide the light source are selected to ensure they have a long life and high stability.

The ORT series transducers can sense both polarity output signals. Torque applied in the clockwise sense along the transducer shaft axis produces a positive polarity output signal while torque applied in the anticlockwise sense produces a negative polarity output signal.

If an optical rotary speed sensor is fitted, a light beam is interrupted by the rotation of a disc consisting of alternate opaque and translucent segments attached to the shaft. Both 60 line and 360 line encoders are available.

The thermal characteristics of the steel shaft are compensated by having an internal temperature sensor monitoring the shaft temperature at all times. This information is then used to correct the modulus of the steel.

Pre-load, note:

All ORT230/240 transducers with a LED on the separate electronics module have a bearing

pre-load spring fitted internally at the left hand

side (pre-load end) of the transducer head when viewing the label of the transducer head and the connector and gland facing towards you.

If there is a possibility of an end load being applied to the transducer, the transducer should be orientated during installation such that the load is applied at the pre-load end (side with the internally fitted spring). Excessive end loads must be avoided and it is recommended that appropriate couplings be used to compensate for axial and radial misalignment.

 Sensor Technology 2016 Page 6 ORT4076IM (Rev 1)

Operation

Powering the transducer

To power the transducer a supply voltage of 12-32VDC is required with a minimum current of 1 amp (to supply peak start-up current). If a Transducer Display ETD is used the ETD will provide power for the transducer. If a Transducer Signal Breakout Unit is used the power supply should be plugged into the DC jack on the box. If a Digital Adaptor Lead is used the power supply should be plugged into the DC jack on the lead.

If a Transducer Display ETD, Transducer Signal Breakout Unit or a Digital Adaptor Lead is not used, then the power supply can be provided by using either the 2.5m Analog or Digital Lead’s 15 way ‘D’ type connector with a supply voltage of 12-32VDC on Pin 1 and Ground on Pin 2.

Note: It is imperative that the voltage does not drop below 12V at any stage.

Using the transducer

1. Switch on the ORT series transducer by ensuring power is supplied.

2. Allow the transducer to carry out its Built In Test (BIT) procedure. Refer to the Built In Test section for further details.

3. Allow five minutes for the equipment to reach thermal equilibrium before making any measurements.

4. Zero the transducer, refer to the Zeroing the transducer section.

5. The transducer is ready for use, examples of different ways to extract data can be found in the Examples of reading/collecting data section.

CAUTION

Only provide power through either the Analog or Digital lead.

Do NOT provide power through both leads simultaneously.

 Sensor Technology 2016 Page 7 ORT4076IM (Rev 1)

Built In Test (BIT)

When the ORT series transducer is switched on it will carry out its Built In Test (BIT) procedure. While the BIT procedure is taking place there will be a series of green flashes from the LED, this is followed by a steady green or an intermittent green flash depending upon the mode of operation.

If the transducer fails its BIT procedure the transducer will display an error sequence identifying the results of each system test. The sequence will repeat until the transducer is powered off.

The error sequence is prefixed with quick succession of red flashes, identifying the LED sequence as an error condition

After a brief pause a sequence of green and red flashes will indicate the results of each system test. The following table lists the tests and their test order, for each test the transducer will output either a GREEN for PASS or RED for FAIL.

8 ORT Parameters Check

If a failure condition exists try power cycling the transducer. Contact the factory if the problem continues.

If an error occurs during operation (solid RED LED) and is not present on power on, the BIT procedure may not identify the fault. If the Zero Input has been wired it is possible to display the Built In Test output, to do this switch the Zero Input ON until the transducer starts flashing RED.

Normal Operation

A solid green LED indicates normal mode and the transducer is working correctly.

An intermittent green flash indicates a special mode of operation; the LED sequences below show the different modes.

Peak Mode

Peak Mode is active, if configured to do so the analog output will output a peak value. Please refer to the Peak Input section for further details.

Analog Scaling

The Analog Scaling status message is shown when a user defined data or voltage scale has been applied to either analog channel. This message is only relevant on ORT240 series transducers.

Warning Signals

A warning signal is indicated when the transducer detects a condition which impedes normal operation or the transducer is operating outside of normal operating parameters.

A warning LED sequence is prefixed with a quick succession of alternating red/green flashes, identifying the LED sequence as a warning condition. A warning sequence will override the normal operation mode LED.

After a pause a sequence of green or red flashes will indicate which warning conditions are flagged. The LED sequence will run through each of the flags in the table below flashing the LED for each. A RED flash indicates that a condition has been flagged; a GREEN flash indicates that a condition is clear.

Once the LED sequence is complete the sequence will restart, this will continue until the warning has cleared.

Sequence

Number

Warning Flag Reason and Action required

Analog Fault CH0 (Analog Torque)

In voltage output mode the analog pin is short circuit, in current output mode the analog output pin is open circuit. Check the analog connector wiring for Analog CH0.

Analog Fault CH1 (Analog Speed)

In voltage output mode the analog pin is short circuit, in current output mode the analog output pin is open circuit. Check the analog connector wiring for Analog CH1.

3 Zero Offset High

A torque offset greater than 10% of FSD has been applied to the measured torque value. The offset is set when the transducer is zeroed, either by the zero input on the analog connector or via a digital command.

4 Exceeded Temp

Shaft temperature has exceeded normal operating conditions. Temperature compensation may no longer be effective or calibration valid.

5 Over Torque Torque greater than the FSD has been applied.

6 Critical Over Torque

Torque greater than 120% of the FSD has been applied. Contact the factory if the warning continues.

7 Head Disconnect

The transducer head has been disconnected. Power off the transducer electronics and check the cabling. This warning is only relevant for transducers with separate heads/electronics

For example, the following sequence would indicate warnings for ‘Analog Fault CH0’ and ‘Zero Offset High‘:

 Sensor Technology 2016 Page 10 ORT4076IM (Rev 1)

Error Signals

An error or fault signal is indicated when the transducer detects a condition which effects its fundamental operation. An error or fault condition will be indicated by a solid red LED. Any error that occurs will latch the LED on and it will remain on until the transducer is reset. An error condition will override a warning and normal mode LED sequence.

If the error persists across multiple power cycles, a fault may have developed with the transducer and you will need to contact the factory.

Peak Input

The peak input is a control signal and has two main purposes. It controls what data gets applied to the torque analog output and it can be used to reset the peaks.

The peak input is activated by grounding pin 8 of the Analog 15 Way ‘D’ Socket. The best way to control the peak input is to use a toggle switch.

Analog Output

When activated any analog output channel configured as “Torque – Auto Assign” will switch from being the current torque value to the highest measured torque value since reset, if the analog output is not unipolar then the torque direction will be output.

Peak Reset

When the peak input is toggled, i.e. off-on-off or on-off-on, all internal peak values on both analog and digital interfaces will be reset to defaults. A peak input toggle will also clear any latched fault condition.

 Sensor Technology 2016 Page 11 ORT4076IM (Rev 1)

Analog Outputs

The transducer has two analog outputs which can be configured to different data values, voltages, currents and scales.

Basic models are preconfigured based on model and options selected, advanced models are user selectable. The configuration of the analog outputs for advanced models is done using Transducer Control; please refer to the Transducer Control manual for further details.

Fail Output

The fail output signals when an error or fault condition occurs within the transducer. The fail output is linked to the internal transducer error flag. Any error condition detected will switch the output on and will remain on until the error clears. This behaviour is different from the LED which latches.

The best use of the fail output is as a safety shutdown signal.

The fail signal is an open collector output. The circuit diagram below shows an example of how to wire an LED to the output.

In firmware prior to version 5 the fail output is shared with the limits module. If the limits module is active the fail output is overridden.

 Sensor Technology 2016 Page 13 ORT4076IM (Rev 1)

Limit Output

The limit output is driven by the limits module. The limits module is a configurable set of parameters which switch the limit output on or off when certain conditions are met. These conditions include triggering when torque or speed goes above or below a set level, as well as more advanced processes like auto reset or triggering after a delay

The limits module is configured using Transducer Control; please refer to the Transducer Control manual for further details.

The limit signal is an open collector output. The circuit diagram below shows an example of how to wire an LED to the output.

In firmware prior to version 5 the limits module does not have a dedicated output pin, instead the limit output is routed to the Fail Output pin (11). When the limits module is active the fail out signal is overridden.

 Sensor Technology 2016 Page 14 ORT4076IM (Rev 1)

Zeroing the transducer

Zeroing the transducer has the effect of introducing an offset to the torque reading. The zero can be used to remove any offset that may have been introduced from its mechanical installation or from idle torque present. It must be stressed that the zero offset is no substitute for correct installation.

When using high zero offsets, care must be taken not to overstrain the transducer. A zero offset will not extend the full scale rating of the transducer, e.g. if a transducer was zeroed at 50% then a further 50% was applied, the transducer will have reached full scale, even though the transducer would be reading of 50%. A zero offset of 10% or greater will trigger a warning condition and will be indicated by a warning LED sequence.

The transducer can be zeroed by using either a digital command or an electrical signal.

There are 3 zero modes that can be used:

 Normal Zero: Sets the zero offset to the current torque reading.  Average Zero: Sets the zero offset to the average of 8 consecutive torque readings.  Fixed Zero: A fixed value can be input and saved. Fixed Zero is only available via the

Transducer Control Software.

Unless the zero is saved, any zero offset applied will be lost after a power cycle.

Electrical Signal

Zeroing the transducer electrically can be achieved by grounding the Zero Input on pin 7 of the Analog 15 Way ‘D’ Socket. The best way of zeroing a transducer is to use a push button. A simple circuit diagram using a push button is shown below.

The zero action is only carried out once the input has been ungrounded. Grounding the zero input momentarily (less than 2 seconds) will initiate a normal zero, grounding the input for longer will initiate other modes. When the zero input is grounded for more than 2 seconds the LED will start flashing to indicate that a new mode has been selected, subsequent mode changes are shown by an increase in flash frequency. The LED will not flash if an error condition is present.

The table below shows the various modes and timings.

Ground Hold Time LED Flash Zero Mode / Action

0 - 2 Seconds None Normal Zero

4 - 6 Seconds 1 Hz Green Flash Average Zero

Greater than 6 Seconds

2 Hz Green Flash

Transducer will save the current zero offset so that it is remembered across power cycles.

 Sensor Technology 2016 Page 15 ORT4076IM (Rev 1)

Digital Command

There are multiple digital commands to select the different zero modes, refer to the transducer communication protocol manual.

Our Torqview and Transducer Control software programs implement these commands providing a simple way of zeroing the transducer.

Resetting transducer to factory default

To reset the transducer to the factory default settings (i.e. the functions set by the factory on purchase) follow the steps below:

1. Turn off transducer.

2. While holding in the zero button, power the transducer. The LED will stay solid green until the zero button is released.

3. Allow the transducer to carry out its BIT procedure.

4. When the LED is solid green all user-adjusted parameters will have been reset to the factory defaults.

TECHNOLOGY

SENSOR

An extensively developed measurement principle is used, in which the intensity of light beams is measured by means of photovoltaic detectors, and the electrical output is used to provide precise indication of the applied torque transmitted by the shaft.

The use of this technique results in a transducer being able to sense torque bi-directionally, have a fast mechanical and electrical response, low inertia, and complete freedom from brushes or complex electronics. The absence of brush gear allows high-speed operation with a continuous rating of up to 30,000 RPM standard. Further increases in RPM are available as an option depending upon shaft size.

The torque shaft is of low compliance ½° maximum torsion deflection on the smaller transducers, and ¼° maximum on the larger transducers, at full-scale deflection. The lamps providing the light source are selected to ensure long life and high stability with the light intensity automatically controlled within the transducer body by a monitor cell.

ORT 230/240 Series Torque Transducers - Data Specification

Note 1: Please consult factory for applications requiring rotational speeds that exceed maximum figures given. Transducers fitted for IP65 will have

running speeds considerably reduced, increased drag torque and accuracy can be affected. Note 2: SM – Static Mode. Dynamic values will depend upon user application and has to be adjusted accordingly. Note 3: Digital averaging can be configured by user to optimise accuracy/frequency response for specific user applications. Digital averaging default

setting is N=16. For details see User Manual. Note 4: >5Khz Sample Rate. Up to 10Khz sample rate possible, please consult factory. Digital averaging also affects the analog output, max analog output

3dB Bandwidth = 5Khz when digital average is 1. Note 5: Output rate figures are calculated from the time taken to capture 10000 torque readings. Testing was conducted with each connection method

configured at its maximum baud rate. The maximum output rate available for CAN and USB is dependant on the transducers setup. USB - USB is a

host based bus architecture, because of this the output rate achievable will be affected by other bus traffic and host activity. USB has two transfer

modes, Single Transfer which requests 1 reading at a time and Bulk Transfer which transfers readings in blocks of 50 Torque/Speed pairs. CAN

Bus - to achieve a Torque reading output rate of 10KHz, the Speed reading output rate must be reduced to 100Hz.

Glossary of terms and definitions used in this datasheet



Accuracy

- The degree of conformity of a measured or calculated quantity, which will show the same or similar results. Accuracy of the overall TorqSense system is limited by the combined error of several factors such as linearity, hysteresis, temperature drifts and other parameters affecting measurements. If errors in the system are known or can be estimated, an overall error or uncertainty of measurement can be calculated.



Digital averaging

– The application of algorithms to reduce white noise. In any electronic system, electronic white noise is mixed with the signal and this noise usually limits the accuracy. To reduce the influence of white noise and increase the accuracy of the system different averaging algorithms can be applied. In the TorqSense system a flying digital averaging technique is applied to reduce the white noise commensurate with the level of accuracy required. However, as any averaging algorithm works as a low pass filter, the more averaging that is applied the lower the frequency response. Therefore, each Torqsense system should be optimised to the customer’s requirements by choosing the right combination of accuracy/frequency response. Please see relevant part of the Datasheet and User Manual.

Transducer Control 5 User Manual (RWT3746IM)

Revision 5, December 2016 - Page 3

Introduction

Transducer Control is an all-round application to unlock the advanced functionality of the ORT/RWT Series Transducers. Transducer Control enables the user to exploit the flexibility of the advanced transducer series by configuring the run time parameters of the transducer to best suit their application.

Transducer Control gives the user complete control of the dual channel analog output by allowing adjustment of the output voltage scaling, zero voltage, data scaling and data assignment. On the digital side the user can control the digital filtering level, adjust the RS232 baud rate and configure the limit controls.

As well as configuring the transducer, Transducer Control can also be used as a readout, providing a simple text display that shows torque, speed and power along with peak values and zero control.

Running Transducer Control & Connecting To A Transducer

To run Transducer Control and connect to a transducer:

1. Ensure that power is supplied to the transducer.

2. Connect the transducer to the computer using either RS232 or USB.

3. Run the Transducer Control program by clicking on the ”Start”/”Windows” button, then “Programs”/”All apps” > “Sensor Technology” > “Transducer Control 5”.

When Transducer Control starts the “Search for connected transducers” dialog box will be displayed. The purpose of the dialog box is to find transducers that are attached to the computer.

Before pressing the “Search” button, select a search filter from the “Select Port To Search” combo box. The items in the list correspond to the default search options and ports discovered on the user’s computer. The filter reduces the time taken to search for transducers by only looking in the selected area.

Transducer Control 5 User Manual (RWT3746IM)

Revision 5, December 2016 - Page 6

The options prefixed with “AUTO” will search for multiple transducers, whereas the COMx options will search for a single transducer on a specific port.

AUTO

AUTO will search for connected transducers on all available ports.

AUTO RS232

AUTO RS232 will search for connected transducers on RS232 ports only.

AUTO USB

AUTO USB will search for connected transducers on USB ports only.

COMx

COMx will search for a connected transducer on the selected COMx port.

If the transducers connection method is known, it is recommended that it be selected, if it is unknown select “AUTO”.

Once an option has been selected, click on the “Search” button. Transducer Control will then search for compatible transducers using the filter supplied. During this process the window will update to indicate the progress of the search, transducers will be added to the listbox as they are found.

If a single transducer is detected the program will automatically initialise the transducer and load the main window. If multiple transducers are detected, the dialog box will require the user to make a transducer selection. To select a transducer, click on the transducer from the list. The transducer will then be initialised and used by the program.

Revision 5, December 2016 - Page 10

Data Ranges

The data range parameters control how data from the selected internal variable is taken and scaled. This feature is useful when the user is working in a specific measurement area and requires a greater change in analog output.

The low and high range values effectively rescale to the Zero and FSD voltages set in the Analog Voltage Scaling section. Values that fall below or above the range are masked off; the range selection applies to both negative and positive sides.

Data Range

The user can select a default scale or opt for a custom scale, by selecting from the “Data Range” combo box.

Default FSD Range

The “Default FSD Range” option scales the selected internal variable based on the FSD rating programmed into the transducer, i.e. 0 to FSD.

User Defined

The “User Defined” option allows the user to adjust the “Range Low” and “Range High” sliders to select a custom scale.

Range Low / Range High

The “Range Low” and “Range High” slider bars control the low and high scale values. The “Range Low” parameter can be set between 0 and 80% of FSD, and the “Range High” parameter can be set between 20% and 100% of FSD. The parameter value is displayed in a text box to the right of each range slider. The value is displayed in an appropriate unit for the selected data variable, i.e. Torque = Nm or the configured unit, Speed = RPM, Power = Watts.

To change the high or low range values adjust the slider bar to the left or right until the number in the text box equals the required value. The difference between the “Range Low” and “Range High” must be greater than 10% of FSD and “Range High” must be a higher value than “Range Low”.

Range effects on resolution

The range selection will in no way effect or increase the resolution of the transducer. The value expansion is artificial and aids only to give the user a greater change in analog output value.

Analog Voltage Scaling

The Analog Voltage Scaling section configures the zero and output range of the analog output channels. The data and range values selected in the Analog Data Select section are scaled to values configured here.

Users can either select from a list of common predefined scales or select a custom scale using the slider bar adjustments.

Voltage Scale Select

The “Voltage Scale Select” combo box lists the available predefined scales and user select modes. When a selection is made the slider bars will adjust to reflect the selection and illustrate the scaling.

The following graphs illustrate the predefined scales that are available. The graphs are scaled against Torque with a standard 0 – FSD Range.

Revision 5, December 2016 - Page 14

User Defined Voltage

If a custom analog output scaling is required select the “User Defined Voltage” option from the “Voltage Scale Select” combo box, then use the “Zero Offset” and “Voltage Swing” slider bars to configure the required scaling. The text boxes to the right of the respective slider bars will display the configured voltage.

Zero Offset

The “Zero Offset” allows the user to change the zero point voltage between 0 and

9.5V. If the “Zero Offset” is increased, the maximum 10V “Voltage Swing” voltage

will be reduced.

This feature is useful if the user has an analog capture device that does not support negative voltages (unipolar only), but requires the direction of torque.

Voltage Swing

The “Voltage Swing” sets the voltage span of the analog output. The voltage can be stepped in 0.1V increments and can be scaled between 0.5V and 10V. The maximum voltage will be reduced if the “Zero Offset” is not 0V.

Unipolar / Absolute Value

The “Unipolar / Absolute Value” checkbox option switches the analog output into a positive only voltage. All input values will be made absolute, making all negative values positive, i.e. -5Nm value will become +5Nm. This has the effect of removing the torque direction from the voltage output.

Revision 5, December 2016 - Page 15

Digital Setup

The “Digital Setup” tab of the User Configuration allows the user to control some of the operational parameters that effect the processing and output of data.

Filters

The torque and speed filters provide data smoothing for conditions where there may be erratic torque and speed readings. The filters apply to the base data captured and will affect both the digital and analog outputs.

Enable or disable the filter for torque or speed by clicking on the appropriate “Filter Enabled” checkbox. If enabled, use the appropriate slider bar to select a filter value. Valid values are 2, 4, 8, 16, 32, 64, 128 and 256.

The filtering algorithms can also be enabled, disabled and adjusted on the fly by sending digital commands via the RS232 and USB interfaces.

Transducer Control 5 User Manual (RWT3746IM)

Revision 5, December 2016 - Page 16

Limits

The limits feature allows the user to configure the transducer to control external processes based on predefined operational parameters. Control is accomplished via an open collector output on the transducers analog connector. There are numerous ways this feature could be utilised, some examples include, system shutdown on overload or triggering a conveyor belt when a nut/bolt has been tightened to the correct torque.

At present there is a single control line, but the limits feature is very flexible, allowing the user to control the output polarity, high and low limit threshold, samples before trigger, and an auto reset function which resets the limit out if the control value falls back between threshold values.

When Limits is enabled the transducer will monitor the selected control channel, when the value falls below the low limit (if enabled) or exceeds the high limit (if enabled), an internal counter is started and is incremented every time a new value is captured and the condition is met. The counter will be stopped and reset if the control value falls back between the low and high limits. When the counter exceeds the “Samples Required Before Trigger” parameter, the limit output will be set to the active state (level configured using the output polarity). If the auto reset has not been configured the limit output will remain latched irrespective of the control channel value. The limit output can only be reset via a system reset or peak switch input toggle.

If auto reset is enabled the limit function will enter a reset state when the control channel value falls back between the low and high limits. If the reset timeout is enabled the limit output will remain latched until the timeout expires, at which point the fail output will return to the inactive state. The reset stage is cancelled if the control channel value exceeds the high or low limits during the timeout period, if this occurs the timeout is disabled and the limit output will remain in an active state. If the reset timeout is disabled, the limit output will be instantly set to the inactive state when the control channel value falls back between the low and high limits.

On transducers with firmware version 3 or 4 the limit output is shared with the Fail Output pin. When limits are enabled the fail output signal is overridden.

On transducers with firmware version 5 the limit output has been moved to a dedicated I/O pin, allowing access to both limit and fail signals.

Refer to the Transducer User Manual for more details.

Transducer Control 5 User Manual (RWT3746IM)

Revision 5, December 2016 - Page 17

To enable Limits click the “Enable Limits” checkbox.

Channel Select

The “Channel Select” option selects the control channel to be used with the limits feature. The user can select between torque and speed.

Output Mode

The “Output Mode” option selects the polarity of the active / triggered state.

Active High Active / triggered state is high, inactive is low.

Active Low

Active / triggered state is low, inactive is high.

Samples Required Before Trigger

The “Samples Required Before Trigger” parameter sets the number of continuous samples that must exceed the high/low limits, before the limit output is set to the active / triggered state.

Use the “Samples Required Before Trigger” slider bar to select a value, the slider is scaled from 0 to 1000 in increments of 10.

Low / High Limits

The “Low” and “High” limits set the trigger thresholds that control the limit output. Low, High or both limits must be selected to use the Limits feature. The High value must not be lower than the Low value and vice versa.

Enable the High/Low limit by clicking the High/Low checkbox, then use the High/Low slider bar to select the trigger level.

Transducer Control 5 User Manual (RWT3746IM)

Revision 5, December 2016 - Page 18

If torque is selected as a control channel then the slider will be scaled from –FSD (counter clockwise full-scale) to +FSD (clockwise full-scale) in increments of 1% of FSD.

If speed is selected as a control channel then the slider bar will be scaled from 0 to FSD in increments of 1% of FSD.

Auto-Reset Limit

The “Auto-Reset Limit” option when enabled will automatically reset a triggered limit output to an inactive state when the control channel value no longer exceeds the low or high limit threshold.

Timeout

The “Timeout” option is an extension of the “Auto-Reset Limit” option and can only be enabled when “Auto-Reset Limit” is enabled. When Timeout is enabled a reset limit event is delayed by the time specified by the Timeout parameter. During the timeout period the limit output will remain latched. The reset limit event is cancelled if the control channel value drops between the low or high limit thresholds during the timeout.

To enable the Timeout option, click on the “Timeout” checkbox (Auto-Reset Limit must be enabled), then use the slider bar to select a timeout duration. The slider bar is scaled from 100ms to 1000ms in 100ms increments.

Misc

RS232

The RS232 settings control the RS232 functionality of the connected transducer.

Baud Rate

The baud rate option selects the RS232 transmit and receive rate for the connected transducer. It is recommended that the user select the fastest mode possible (115200bps), as lowering the speed will reduce the throughput and add latency to programs interrogating the transducer.

In some circumstances it may not be possible to run at very high baud rates as some systems, especially embedded devices, may not be able to generate such high baud rates. Long cable lengths may also hinder the use of higher baud rates. To accommodate all users we have provided a selection of three baud rates:

 9600bps  38400bps  115200bps

To change the baud rate, select the desired option from the “Baud Rate” combo box. Please note that a baud rate change will only take effect after a transducer reset.

Auto Reset

The “Reset Percentage” controls the reset point of the Peak Torque Auto Reset feature. The Peak Torque Auto Reset feature monitors the captured torque readings and stores the peak torque value. The peak torque value is automatically zeroed

Transducer Control 5 User Manual (RWT3746IM)

Revision 5, December 2016 - Page 20

when the current torque value drops below the “Reset Percentage” of the stored peak value.

To configure the percentage, use the slider bar to select a value between 5% and 95%.

Update Transducer

The “Update Transducer” button will upload the settings to the Transducer. Transducer Control will validate the settings before transmission to ensure that there are no errors. If an error is detected an onscreen prompt will notify the user and direct them to a resolution.

If all tests pass the validation check, a progress bar will be displayed to indicate the progress of the settings upload, a message will be shown to indicate success or failure.

Transducer Control 5 User Manual (RWT3746IM)

Revision 5, December 2016 - Page 21

Zero Offset

The Zero Offset feature sets a fixed torque offset value. The zero offset can be used to remove any offset that may have been introduced from its mechanical installation or from idle torque present. It must be stressed that the zero offset is no substitute for correct installation.

Any torque value up to FSD is permitted; values over 25% of FSD are allowed but are not advisable. Using an offset of over 25% will flag the High Zero Offset warning. When using high zero offsets, care must be taken not to overstrain the transducer. A zero offset will not extend the full scale rating of the transducer, e.g. if a transducer was zeroed at 50% then a further 50% was applied, the transducer will have reached full scale, even though the transducer would be reading 50%.

The zero offset can be temporary overridden by the digital zero commands or the Normal/Average Zero Input. When the transducer is power cycled the saved zero offset will be restored.

The offset can be entered manually or set from one of 3 options.

Offset Torque Value

The “Offset Torque Value” text box is the torque offset value. The offset is subtracted from the captured torque readings. Manually type in the required offset, or select from the 3 options.

Current Zero

The “Current Zero” button sets the “Offset Torque Value” to the current zero offset value of the transducer.

Clear Offset

The “Clear Offset” button sets the “Offset Torque Value” to zero.

Load Applied

The “Load Applied” button sets the “Offset Torque Value” to the current unzeroed torque value.

Save Zero Offset

The “Save Zero Offset” button saves the “Offset Torque Value” into the transducers memory. The offset will be retained across power cycles until it is cleared by this window or by the zero input on the transducer.

Transducer Test

Output Monitor

The Output Monitor displays the capture data generated by the transducer.

The peak, min and max values are generated by the transducer based on the torque, speed and power readings captured.

Zero

The “Zero” button instructs the transducer to zero the torque readings. The transducer zeros the torque readings by recording the current torque as an offset, the offset is then subtracted from all future torque readings.

AV Zero

The “AV Zero” button works in the same way as the “Zero” button, but will base the offset value on an average of eight torque readings rather than one.

Reset Peaks (Torque)

The “Reset Peaks” button instructs the transducer to reset all peak torque values.

Reset Peaks (Power)

The “Reset Peaks” button instructs the transducer to reset all peak power values.

The “R” buttons instruct the transducer to reset the appropriate peak values.

Transducer Status

The Transducer Status segment displays the current transducer status. The status code is extracted from the transducer and displayed on screen. The transducer LED status sequence is derived from this status code.

System Status

The System Status represents the overall status of the transducer. There are three possible system states:

System OK

Transducer is operating normally.

System Warning

Transducer has detected an error which requires user intervention.

System Error

Transducer has detected a system fault.

Status Code

The Status Code is the value that has been extracted from the Transducer and represents the current status. The Status Code is a collection of binary flags that are combined together and shown in numeric form.

The status code is split into 3 categories, Information, Warning and Error. Each category is composed of a number of flags which identify the status of each test item. When the status code is retrieved from the transducer it is decoded and the status of each item is displayed onscreen.

Transducer Control 5 User Manual (RWT3746IM)

Revision 5, December 2016 - Page 24

The meaning of each category and flag is described in the following sections.

Information

Information flags inform the user of operational conditions.

Peak ON

Peak switch is ON.

Custom Analog Scaling

A non-standard analog output setup is being used.

Limits Triggered

The limits feature is in an active/triggered state.

Warning

Warning flags inform the user of conditions that need user intervention or conditions that user should aware of.

Analog Channel 0 / Analog Channel 1

Analog output load fault detected. The actual problem depends on whether the output is voltage or current, in either case there is a wiring fault.

Voltage - Fault caused by a short or low load resistance. Current - Fault caused by a high load resistance or open load.

High Zero Offset

A torque zero offset greater than 25% of FSD is in use. Any offset value is allowed, but the warning is asserted because it is potentially a very dangerous circumstance, a user may not realise that an offset is present, then overscale the transducer and damage connected equipment.

Exceeded Temperature

The transducer is operating outside of the -10°c to +50°c temperature range. The transducer may not operate correctly.

Overscale

A torque of over 101% of FSD has been applied to the transducer, measurement accuracy cannot be trusted.

Critical Overscale

A torque of over 120% of FSD has been applied the transducer, at this level measurements will have a low accuracy and there is a danger of permanent damage to the transducer. Reduce the torque level.

Head Disconnect

The torque measurement head for transducers with external electronics has been disconnected. Power off the electronics, reconnect the torque head and power on.

Transducer Control 5 User Manual (RWT3746IM)

Revision 5, December 2016 - Page 25

Error

Error flags indicate that a system fault has been detected. System faults cannot be corrected by the user. If a fault condition does occur, try power cycling the transducer. If the fault does not clear the transducer will have to be returned for service.

Electronics Fault (Firmware Version 5)

An electronics fault has been detected.

Head Disconnect (Firmware Version 3/4)

Please refer to the previous section for a description of this error. In firmware version 5 this error was reclassified as a warning as it is a condition that is correctable by the user.

SAW Error

A SAW error indicates that the shaft attached SAW devices are not operating within normal parameters.

Failed Temperature Sensor

A failed temperature sensor error indicates that the transducers internal shaft temperature sensor has malfunctioned. When the temperature sensor fails the transducer will no longer compensate the torque readings for changes in temperature, which will cause a loss in accuracy.

Irregular Internal Voltage

An irregular internal voltage error indicates that main processor has detected that one of the internal voltage rails is operating outside of normal parameters.

Data Configuration Invalid

A data configuration invalid error indicates that main build configuration has been corrupted.

Calibration Invalid

A calibration invalid error indicates that the calibration data has become corrupted.

SAW Parameters Invalid (RWT Transducers)

A SAW parameters invalid error indicates that an internal configuration structure has become corrupted.

ORT Parameters Invalid (ORT Transducers)

An ORT parameters invalid error indicates that an internal configuration structure has become corrupted.

One of the peak options has been selected in either the transducer control software or by using the analog lead contact closure on pin 8.

Analog Scaling

The full scale of the analog out has been changed to a userselected scale in the transducer control program.

Limits

Limits output has been triggered

Analog Fault CH0

In voltage output mode the analog output pin is short circuit, in current output mode the analog output pin is open circuit. Check the analog connector wiring on Channel 0.

Analog Fault CH1

In voltage output mode the analog output pin is short circuit, in current output mode the analog output pin is open circuit. Check the analog connector wiring on Channel 1.

Zero Offset High

There may be an offset applied to the current torque applied value because the ‘Zero Peaks’ has been pressed while torque, greater than 10% of the fsd, has been applied.

Exceeded temp

Shaft temperature has exceeded normal operating conditions. Temperature compensation may no longer effective or calibration valid.

Overscale

Torque has been applied greater than the specified FSD.

Critical overscale

Torque has been applied greater than 120% of the FSD. Contact factory if warning continues.

Head Disconnect

Lead has been disconnected from the transducer.

Capture Board

The DSP has failed to initialise. Power cycle the transducer. Contact factory if error continues.

SAWS

A SAW device has failed. Contact factory if error continues.

Failed Temp sensor

The infrared temperature sensor has failed. Temperature compensation is ineffective. Contact factory if error continues.

Irregular Voltage

One or more of the internal voltages is not within specification. Check the input power supply is within specification of the data sheet. Contact factory if error continues.

Additional Information

There is no requirement to install LabVIEW because TorqView is a self-running executable file.

However, if LabVIEW is installed and there is a requirement to make unique programs or allow TorqView to communicate with other LabVIEW programmes, VI’s are available from Sensor Technology on the website www.sensors.co.uk at: http://sensors.co.uk/products/pages/labvi.html
