Alarms
The section lists the possible alarms, and their causes and effects, that may occur during the operation
of the X
VAC module.
List of Fatal Alarms
Alarm Management in Local Control
When one of the alarms listed in Table 13-1 occurs while the XVAC module is operating in local control
(i.e., when the X
TRA system is booting up or when a fatal error occurred on the XTRA system), the
following actions are taken:
• Vacuum pumps are switched off
• The red alarm LED is turned on
• The system beep is sounded
• The code corresponding to the alarm is shown on the X
VAC LCD display
• The system cuts off the supply of the 230VAC Intra pump by the activation of the safety relay
(only for alarms F1, F2, F3, F4, F5)
To stop an alarm, the operator must power off the module and resolve the cause of the alarm.
If the EEPROM failure alarm (F11) occurs due to the failure of calibration coefficients test, the system
automatically repairs the problem by overwriting the wrong coefficients with a default set of
coefficients.
Alarm Management in Remote Control
For the XVAC module, every point made in “Alarm Management in Local Control” on page 13-8 is also
true when operating in remote control.
For the X
TRA system, there are two other causes of alarms when operating in remote control:
Error Service Code(s) Error Family Operator Response
F1 Over temperature (in the inner module) • Switch the system off
• Ensure that the fan in the rear of the
module is not occluded
• Switch the system on
• If the problem persists, call the
authorized technical service
F2
F3
Overpressure • Switch the system off
• Switch the system on
• Call the authorized technical service
F4
F5
Error in pressure measurement • Switch the system off
