Each of the isolated digital input channels accepts bi-directional 10 \~ 30 VDC voltage inputs. This means that both positive and negative voltage can be applied to an isolated input pin (VIN). Figure 2 shows how to connect an external input source to one of the module's isolated input channels.

Figure 3.6 Isolated Digital Input Connection

3.3.4 Isolated Digital Output

The WISE-750 refers the digital output as alarm. When the inspection criteria is reached, the alarm would be pulled to high automatically, in order to trigger the external equipment. The signal connection is shown in figure 3.

Figure 3.7 Isolated Digital Output Connection

3.4 Hardware Installation

WISE-750 can be integrated with a DIN-Rail mount for easy operation.

1. Take out the mount kit from the package.
2. Install the DIN-rail kit using the 3 screws provided in the pack.

3.5 Field Wiring Considerations

When you use WISE-750 module to acquire data from outside, noises in the environment might significantly affect the accuracy of your measurements if due cautions are not taken. The following measures will be helpful to reduce possible interference running signal wires between signal sources and the WISE-750 module.

The signal cables must be kept away from strong electromagnetic sources such as power lines, large electric motors, circuit breakers or welding machines, since they may cause strong electromagnetic interference. Keep the analog signal cables away from any video monitor, since it can significantly affect a data acquisition system.
If the cable travels through an area with significant electromagnetic interference, you should adopt individually shielded, twisted-pair wires as the analog input cable. This type of cable has its signal wires twisted together and shielded with a metal mesh. The metal mesh should only be connected to one point at the signal source ground.
- Avoid running the signal cables through any conduit that might have power lines in it.
If you have to place your signal cable parallel to a power line that has a high voltage or high current running through it, try to keep a safe distance between them. Alternatively, you can place the signal cable at a right angle to the power line to minimize the undesirable effect.

3.6 Ethernet Connection

The WISE-750 has two LAN port with RJ45 connector. To connected with WISE-750, you should use at least CAT 5e cable with RJ-45 connector to connect to the WISE-750.

The WISE-750 supports daisy chain. The topology could be expanded with this feature. (Figure 3.7)

Figure 4.6 Multiple WISE-750 being listed in device tree view

4.3 IP Configuration

The IP Configuration is the first thing to do when you start configuring the WISE-750. The device itself has a default IP setting of 10.0.0.1. In order to successfully connect to WISE-750 in the beginning of using the device, you need to configure your NIC IP connected to WISE-750 to the same section (10.0.0.x with sub-net mask 255.255.255.0). After that, you can revise the IP in IP Config. Press the button to set the IP and then the WISE-750 will reboot automatically to apply the setting.

Note! It's suggested to shut down the Windows firewall and the anti-virus software while connecting to WISE-750. The WISE-750 relies on UDP communication, which is likely to be blocked by firewall and antivirus.

4.4 Overview of WISE-750 Operation

The WISE-750 follows Figure 4.7 in its operation. An iteration cycle includes data acquisition, calculation and communication. The data acquisition starts right after the end of previous cycle to retrieve analog data (vibration data) into the system. After acquisition, WISE-750 will execute the corresponded calculation and judgment based on the judgment type. Then, the result will be sent out through Ethernet and digital output. Another cycle will start right after the end of the communication session from data acquisition.

Figure 4.8 Trigger and Cycle Count

If the section count is set to 0, this would act as continuous mode. Each cycle would be started right after previous cycle until stop trigger happens. In this mode, the trigger would act as a gate to control the iteration. See Figure 4.9.

4.6 Trigger Settings

4.6.1 Trigger Source

Select the trigger source via the options in the combo box. Options are: None, Digital Input, and Analog Input from the respective channels to be chosen from. Whenever the trigger is set to None, WISE-750 will run right after the setting is downloaded to the machine. Otherwise, the cycles would start when receiving the trigger signal/action.

4.6.2 Trigger Types

Digital Trigger

The digital trigger of WISE-750 uses the level trigger. There are two options "Active High" and "Active Low" to trigger the iteration cycle. That means, a trigger is generated whenever the level of trigger source is HIGH (Active High) or LOW (Active Low) based on the settings. On the other hand, in the context of analog trigger, the options would be changed to beyond (>) or under (<) trigger level. In the meantime, the filter can also be set (see the section Filter).

Figure 4.10 describes the action in the context where the type is set to Digital Trigger and Active High. In the beginning of the cycle, the trigger signal is high. In this situation, a trigger would be generated. The triggers are also effective when the signal turns to high, just like the consecutive two pulses. Whenever the process idles and meets the active zone, the process cycle will be triggered. This mechanism could also be applied when setting type to Active Low.

Figure 4.10 Digital Trigger

Analog Trigger

When the trigger type is set to ">" (greater than) level, a trigger will be generated when the incoming signal condition is fulfilled.

See Figure 4.11.

Figure 4.11 Analog Trigger

Triggers won't be generated when the cycle is already running. The trigger signal would be referred to as ineffective when the process is already running. See Figure 4.12.

Figure 4.12 Analog Trigger and Cycle

4.6.3 Trigger Level

This would only be available when using analog triggers. This is the trigger voltage level. The trigger would be generated when the voltage passes through this value. This field would only be available when the trigger source is analog input.

Filter

Figure 4.13 Left: Trigger Acquisition. Right: No Further Action

Refer to Figure 4.13. The filter parameter sets a sample count. The sample count is a period to measure if all of the values within these period of time exceed the trigger level. If they are, this would allow trigger generation. If they aren't, no trigger would be generated.

4.7 Operation Modes

There are three modes that could be run in the WISE-750. They are Datalogger, Feature Extraction, and Intelligent Mode respectively. You can set them in the WISE-750 Utility. They are independent modes. They each have their own functions respectively. The function of each mode cannot be used in other modes. For example, the Datalogger function in Datalogging mode cannot be used in Extraction Mode and Intelligent Mode.

4.7.1 Datalogger Mode

The Datalogger Mode is hte default mode when first starting the application. No matter the final application is in Feature Extraction Mode or Intelligent Mode, this function is always used in the starting stage of the application. After data logging, users can analyze the data then understand the data features and will be able to set the criteria afterwards. To use the datalogger, switch the utility to "Feature Extraction" Page.

Options and Parameters:

Data Type: Choose Feature Values or Raw Data to set the data type you'd like to saves the data for.

File Count: The datalogger will save corresponded number of files according to this parameter. For non-zero file count setting, the logger will save corresponded number of files to the directory you set. For file count 0, the logger will save the files until you press the stop button. The settings in different mode will result in different types of data logging:

• Raw Data Mode: the datalogger will save data to file with the number of section length data written in the file and save number of files for this parameter. For example, if you set the section length for 2048 and file count for 100, there will be 100 files saved and 2048 rows of data in each file.
• Feature Extraction Mode: the datalogger will save feature data (calculated in every iteration of section length) to file with 100 rows of feature data in each file. The file count sets the number of files to be saved.

Destination: set the data logger directory in this PC.

Configuration Process:

1. Select the data logging types. The option "Feature Values" will save the feature values to the destination you set.

2. Enter the file count in the box.

3. Click "..." button to enter a destination of your data.
4. Click on the Start button then the data logging will be started.

4.7.2 Feature Extraction Mode

The Feature Extraction Mode allows you to set the alarm using the feature values we provided already in WISE-750. They are maximum, minimum, peak value, peak to peak and RMS respectively. To employ this mode, the alarm type of WISE-750 needs to be set to "Feature Extraction" in Configuration Page.

Alarm Threshold Setting

You can choose which feature value you are concerned about by checking the box and then entering the criteria. Finally, press the button "Save To Device" to set the alarm criteria to WISE-750. After that, the condition monitoring using criteria setting will be started.

For the details of all the feature values, please refer to Appendix B.

4.7.3 Intelligent Mode

Machine Learning Model Building

The Intelligent Mode operates the condition monitoring by machine learning algorithm. The WISE-750 allows you to set models for each channel. The training data set is pre-processed by FFT to transfer from time domain to frequency domain. Follow the steps below to employ Intelligent Mode in WISE-750:

1. Set the alarm type to Machine Learning and the channels in Configuration page.
2. Switch to ML Modeling page
3. Set the number of data set you'd like to train the model with. Every data set is saved to a file. Each file contains data count of half of the section length. For example, if you set the file count to 100 and section length to 2048, there will be 100 files and each file containing 1024 data comes after FFT (Fast Fourier Transform).
4. Set the destination. This would be the path of the data set. We strongly suggest you to fix this path once you decide to use this mode.
5. Press start then the datalogger will start to retrieve the data set for machine learning. The datalogger will follow the parameter you set in Configuration to get the data. If you set the trigger, the datalogger will get data until the trigger happens.
6. After retrieving the data set, the dataset will be listed in the column Dataset Selection. Select the dataset you'd like to train the model with.
7. Press start. This will train the model and also download the model to each selected channel.

Alarm Threshold Setting

The training session will build and download the model to the WISE-750. In the inference session, the WISE-750 will indicate if the iteration is OK or NG. The WISE-750 will give a score to indicate the status of the measured machine/component. The score is calculated using success rate in the past N iterations, while N is user-configurable in Alarm Setting page. For example, if the number is set to 200 and there are 160 Oks in the past 200 iterations, the score will be 160/200 × 100 = 80 . Users need to set an alarm threshold for the score. Hence, the WISE-750 will generate the alarm when the score is lower than the threshold. Then, press the button to set the parameters for the device.

4.8 Device Communication

WISE-750 supports instant data reading and input from protocols. To retrieve instant values from WISE-750, please make sure the WISE-750 is running and then follow the mapping table to get corresponded values.

4.8.1 Modbus

WISE-750 provides Modbus mapping for instant feature values and inspection results. For detailed mapping table, please refer to Appendix C.

4.9 Alarm Generation

Alarm thresholds could be set in WISE-750. The setting interface is in the "Feature Extraction" and "ML Modeling" page respectively. The inspection result could either be retrieved from communication interfaces or corresponded digital output. For example, if WISE-750 finds that channel 0 fail to pass the threshold, the digital output 0 will be set to High level. Otherwise, in the normal situation, the digital output will stay in Low level. For the communication protocol table and digital output specification, please refer to Appendix A and Appendix C.

4.10 System Requirements

The installation package installs essential components altogether, including Python and Tensorflow. The system should be a 64-bit Windows system, at least Windows 7 and suggested to be Windows 10.

Algorithms

■ AVG (Average) - Average of the numbers, a calculated "central" value of a set of numbers.
■ MAX (Maximum) - The maximum value of Y-axis on the plot.
■ MIN (Minimum) - The minimum value of Y-axis on the plot.
- Peak To Peak - The difference between the maximal positive value and the minimal negative value of a waveform.
- Peak - The maximum of the absolute of the waveform

$$ \text { Peak } = \operatorname{Max} (| F (n) |) $$

RMS - The root mean square (abbreviated RMS or rms) is defined as the square root of the mean square (the arithmetic mean of the squares of a set of numbers).

$$ \mathrm{RMS} = \sqrt {\sum F (n) ^ {2}} $$

Measurement of PCL-M10 - The formula to transform the voltage to vibration value is (voltage)/(sensitivity). PCL-M10 itself will have a DC voltage of 5V in default.

So, the formula to transfer PCL-M10 voltage to vibration is

Acceleration = (Voltage - 5 / 0.08) g

For example, a 6V in measurement could be transferred to (6-5)/0.08 = 12.5g.
