Before we release the two connection visaVaporization hydrogen peroxide HPP270 probeVideo tutorial:
In this video, we will show how to connect HPP270 probe toIndigo500 data processing unit.
The following is a transcription
Hi, I'm Joni Partanen.In this video, let's take a look at how to connect HPP272 hydrogen peroxide probe to Indigo500 data processing unit.
Indigo500 additional features include more analog output of a data processing unit.Indigo520 has four analog output, and the probe only two.Indigo500 more power options can also be attached.We now see the device using the main power supply.If you prefer Ethernet communication, can also use the Modbus TCP protocol.
Here I will show you can use in your application several sample process connection methods.Let's use this two kinds of connection and installation HPP270 probe.
Then can connect instruments and data processing unit.It is worth mentioning that Indigo520 can support two probes at the same time.But in the current scenario, I will only use a probe.Probe is connected now, we can begin to set the display screen.
Please note that HPP270 probe will start cleaning process in the first place.Removal process has now started, we can know it from active in the notice of running status.We'll be the first to set is display some of the readings.
Go to the "Home Settings" (Home page) : use HPP270 probe, we can focus on concentration of hydrogen peroxide.Let's use it as the first parameter, the second can be a relative degree of saturation, the third can be the temperature.
Now we also can set the diagram view content.For example, hydrogen peroxide concentration and the relative degree of saturation.Then a graphical time range, we set to 15 minutes.Now, we can see some reading, but please note that we can only see the temperature.This is because the removal process continues.
We want to do next is probably will be the measure data output to a control system or data acquisition system.Go to "Menu" (Menu) > "Outputs" (output), we will use the analog output.For this application, we will make the first channel output is set to the concentration of hydrogen peroxide, and then set the minimum value of 0 PPM, the maximum value is set to 2000 PPM.
We can also set the "Error output" (the Error output).If there is a problem, such as probe disconnect or similar situation occur, data processing unit will output 3.6 ma.We are in a second output for the same operation, and relative saturation as the output parameters.4 ma said 0% of the relative degree of saturation, 20 ma said 100%.Error output and interception of lower limit can be consistent.We would also like to know the temperature, so let's set the third output to the temperature.Assume our application temperature is 0 to 60 degrees Celsius.
Now output configuration is complete, check the control system of value is the same as the data processing unit and output.We tested whether the analog output according to the expected output to the system.Indigo500 data processing unit具有测试模式功能。我们将首先测试通道 1，我们通过启用测试模式来实现，测试模式会将模拟输出值强制性设置为 4 毫安。
Now, I will use the multimeter to demonstrate the simulation output.Let's move the switch to the ma model, and to ensure that we in this measurement is dc amps.We will open the lid, you can see the analog output terminals 1, 2 and 3.We are the first channel to 4 ma output.If I put the probe is negative, I can read on the multimeter 4.01 ma.Looks no problem.
Let's test the maximum value, namely 20 ma.Reading into 20.01.Looks pretty good also.Now, we repeat this measurement for all three channels.All three channels through the test, let's close the lid and stop the test mode.Please note that this is very important, began to run, you don't want to in the actual process equipment is still in the test mode.
We're now going back to the main screen, here we can see the readings: the vaporization of hydrogen peroxide concentration of 2 PPM, relative degree of saturation is 10% RS, temperature of 23.2 ° C.Here, we can see in the chart shows now HPP272 probe is connected to the data processing unit and installed in the process.After testing, analog output is configured correctly and reading the output in line with expectations.Then we will ready to measure.Thank you for watching!
