Rausch KamPac Pressure Testing In POSM

Using the Rausch KamPac pressure testing system, POSM has the ability to take air or water pressure measurements in pipes at joints, laterals and repair sections. To begin using the KamPac system in POSM ensure the system is registered and enabled.
To enable KamPac the user must open the Edit Preferences the click on the Setup RS232 and
External Devices button, This will open the preference page where the KamPac settings are.

Figure 1: KamPac Setup

The system should already be Unlocked when it arrives from Rausch. If a key change occurs
(change of windows or hardware in the system), please contact POSM technical support at 859-274-0041 to obtain a new key.
To enable the KamPac system ensure the Enable KamPac checkbox is checked and select if the system will be using Air or Water for testing.
Next, start a session in POSM to begin adding KamPac data.


Figure 2: KamPac Tab in a Session

When the KamPac system is enabled a new tab will be displayed in POSM. Click on the KamPac tab. When the first KamPac pressure test is ready to be performed press the Activate button to activate the system. This will only need to be done once during a session. The 3 sliders on the system allow the user to adjust the Bladder Pressure, which is the pressure of the balloons that press against the pipe to create a void. This slider adjusts the system in Bar pressure. The Testing Pressure slider allows the user to adjust the mBar pressure inside the void during testing. The Test Time allows the user to adjust the time a pressure test will take place. This slider operates in seconds.
The Test Chamber Pressure displays a status of the current pressure inside the test chamber. The Activate button activates the system.
Secure Bladders will secure the balloon bladders against the pipe wall with .5 bar of pressure. This is useful for testing to ensure the system is in the correct position.
The Fill Bladders button will fill the bladders to the Bar pressure set with the Bladder Pressure slider. This also sets all the variables required in the system to perform a pressure test.
Cancel will cancel a Secure Bladder, Fill Bladder or a pressure test.


Figure 3: KamPac with Macro Interface

To see all of the KamPac commands the user may press the K button in the Rausch Macro interface. This will open the KamPac command section of the Macro. This interface is useful for debugging the system should an issue occur.


Figure 4: Activating the KamPac

Once the Activate button has been pressed it will be greyed out. The system is now ready to begin testing once the status says “Ready”.
To begin a pressure test position the system into place and press the Fill Bladders button.


Figure 5: Securing the Bladders

Once the system has been activated press the Fill Bladders button to secure the system against the pipe. Once it is complete the status will change to Bladders Filled.
Add an observation in POSM for the pressure test. A KamPac pressure test may be added to any observation in POSM. The user may wish to uncheck the Take Picture and Take Clip buttons before adding the observation so that the end pressure chart only shows the pressure test. Otherwise there will be two pictures for the observation.
To add a pressure test, left click on the new observation, then right click on the observation to display the edit menu.


Figure 6: Add Pressure Test

Once the edit menu has been displayed select Add Pressure test.


Figure 7: Confirm add pressure test

A box will pop up confirming a request to add a pressure test, press “Yes”.


Figure 8: Pressure Test in Progress

During the pressure test a graph will be displayed showing the status of the chamber pressure verses time. When the test is complete this graph will close and the KamPac bladders
will deflate.


Figure 9: Finish KamPac Pressure Test

To complete the observation for pressure testing the user must answer if the test passed.
Select Yes or No from the Passed drop down box. POSM will automatically fill in the Test Type, Bladder Pressure, Chamber Pressure and Test Length from the slider data. The pressure test
is now complete. The data will print out on the POSM reports.
