SCM Annual Functional Testing
Perform a SCM Functional Test annually. This test will verify that the SCM application will detect and alarm on a leak
condition. This test should be performed during times when there is no dispensing.
1. If the channel is Enabled, disable the channel. At the T5 FMS console (via LCD or TSA), navigate to the SCM Control
screen. Press the Enable/Disable button to disable the channel.
2. Remove the plug in the Leak Generator (LG) port on the SCCM. Connect the TS-SCMCAL (Leak Generator Kit) to this
port.
3. Switch the toggle valve to the DN (closed) position.
4. Enable the channel. Wait for the containment vacuum levels to reach normal operating levels.
5. Switch the toggle valve to the UP (open) position.
6. The vacuum levels will then fall, which could take several minutes for large containments. Verify that the console
displays an alarm.
7. The channel will be disabled by the SCM application. Remove the TS-SCMCAL. Apply TFP tape sealant to the threads
of the Leak Generator Port Plug. Replace and tighten the plug.
8. At the T5 FMS console (via LCD or TSA), navigate to the SCM Control screen. Press the Reset Alarm button to
enable the channel, then press the Enable/Disable button to enable the channel. Resume normal operation.
9. If the SCM Annual Functional Test passed, please skip this step. If the system did not catch the leak and the test failed,
disable the channel and run the pre-operational tests. Perform the annual test again. If the channel still fails to detect
the leak, please contact FFS Technical Support.
