6. When the message Open Leak Toggle Valve appears, switch the toggle valve to the UP (open) position. SCM will learn
the vacuum decay curve and display Learning Decay Curve on-screen. The vacuum level will begin to fall.
7. When nished, the message Learn Completed – No Errors is displayed on-screen and the Not Learned indicator will
become inactive.
Note: If any errors are encountered at any time during the Learn Process, the screen will display the appropriate error
message and the Not Learned indicator will be active. Refer to the Alarms chapter of this guide for information on
troubleshooting any errors that are displayed.
8. Once the containment has been successfully learned, enable the containment on the Containment Control screen with
the leak generator open. The console will automatically begin a test on the containment. This test should fail, forcing
the containment into alarm status.
9. Close the leak generator. To clear the alarm, navigate to the Containment Control screen and choose Reset Alarm. If
the Auto-enable on Reset option is turned on in the SCM section of programming, the containment will be automatically
enabled after resetting the alarm condition and will automatically begin a test on the containment. This test should
pass, allowing SCM to continue to monitor the containment. If this test fails, isolate why the test failed, make necessary
repairs, and then retry the test.
10. Remove the leak generator and replace the leak generator plug. Apply TFP tape sealant to the threads of the plug,
then tighten the plug. If alarms or errors occur, refer to the Alarms chapter of this guide. When the condition is
corrected, restart the Learn Process.
Learn Messages
Learn Message Description
Existing Vacuum Detected The Learn Process was started with .5" Hg or more existing in the containment. The Learn Process
needs to be restarted at 0" Hg.
Learned The containment has been Learned with no errors.
Learning Decay Curve Displayed during the Learn Process to indicate that the calibrated leak decay curve is being recorded.
Learning Evacuation During the Learn Process, SCM is recording the time and vacuum levels while evacuating the
containment.
Failed to Reach Target
Vacuum / Time Limit
Exceeded / Pre-Existing Leak
A vacuum leak is present when the leak generator should not be open.
No Leak Detected Vacuum level is constant or has risen while Learning the decay curve.
No Leak Detected/Time Limit
Exceed
The leak valve was opened when prompted, but the leak valve was closed before the Learn Process
was completed. Restart the Learn Process and open the leak valve when prompted. Close the leak
valve after the Learn Process has completed.
Not Learned The containment has been programmed, but the containment has never been Learned. Refer to the
SCM Learn Process section to Learn the containment. Follow all Warnings, Cautions, and Notes prior
to Learning the containment.
Open Leak Valve This is a required step during the Learn Process. When shown, open the leak generator.
Pump Request Ignored SCM sent a request to start the STP, but the TPI or the relay module didn’t send conrmation that the
STP was running. The STP may be used or disabled by other applications.
Sensor Malfunction This message is displayed if the containment is enabled in the setup, not Learned, and the sensor
was disconnected. Verify sensor wiring.
Exceed Time Limit to Reach
Target Vacuum
Evacuation Learning exceeds the limit.
Time Out for Leak Valve Not
Opened
The leak valve is not open during the Learn Process. Restart the Learn Process and open the leak
valve when prompted to by the console.
