Enabling/Disabling SCM
After learning the channel(s), each channel will need to be enabled to allow containments to be monitored. The
Containment Status reects the current status of the channel.
Enabling SCM Channels
At the T5 FMS console (LCD or TSA), navigate to the SCM Control screen. Press the Enable/Disable button to enable
the channel.
Only while the channel is enabled will that channel continuously monitor and test vacuum levels by activating the STP
as necessary. Normal SCM operating vacuum level is between 2" Hg and 5" Hg. During vacuum recharge periods, it is
normal for the vacuum levels to reach 6" Hg.
Note: A channel will not enable properly if it is not learned, in an alarm status, or if an error condition exists (such as a
sensor malfunction). An alarm must be reset to enable a SCM channel.
Disabling SCM Channels
At the T5 FMS console (LCD or TSA), navigate to the SCM Control screen. Press the Enable/Disable button to disable
the channel.
Important: While the channel is Disabled, SCM will neither maintain nor test containment vacuum levels.
Disabling the channel will force the console to display a Containment Not Enabled warning. This warning will also appear
on the SCM History Report. The channel may be re-Enabled at any time.
If alarms or errors occur, please refer to the Alarms chapter of this guide.
