• Timeout communication failure : Communication on the X
TRA
-X
VAC
RS-422 serial connection
has timed out (for example, because of a damaged cable or loose connection).
• Serial communication failure : A double communication error on the same communication
window on the X
TRA
-X
VAC
serial line has occurred.
When an alarm occurs (F1 to F11 and the two listed above) during or immediately after the prelink
phase, the X
TRA
user interface displays the message “Vacuum pump out of order”. The X
TRA
system
will continue working as if the X
VAC
module were absent.
When an alarm occurs during the T1 test (alarm F10 or F11) when the boot is over, the X
TRA
system
will consider the X
VAC
module absent without displaying any message.
When one of the two serial connection failures (listed above) occurs, the X
TRA
system switches from
remote control to local control. In addition, the red alarm LED lights up. Unlike with the other alarms,
in the case of the connection failures, the module continues to work (in local control).
