ANAESTIVAC 1 & 2 –
The pressure exceeds the high-pressure alarm setting while the turbine is turning (see § 2.5.3 for setting
information on the MILLENIUM system),
This fault triggers the malfunction light after a 1-minute delay.
The recoverable voltage-free contact
A general alarm change-over contact (C, NO, NC) can be carried over remotely.
This contact is provided for 250 Vac maxi tension and 6A maxi intensity.
This contact is switched when a fault occurs:
Voltage is present,
Loss of current,
Temperature breaker,
Pressure.

ANAESTIVAC 2 panel
Overview
1.
Turbine A or B On/Off switch:
"Off" position: the turbine is switched off.
3
"On" position: the turbine will run
according
to
the
position
of
the
auto/manual switch or the pressure level
in the system.
2.
Auto/Manual switch:
"Auto" position: the pressure level in the
3
system determines when the turbine
starts.
"Manual" position: force starts
the
turbine.
3.
Green "turbine A or B operating" light: comes on when the turbine is operating in either manual or
automatic mode.
4.
ANAESTIVAC 2 MILLENIUM automated system: see § 2.5.3.
5.
Master switch: cuts the electricity supply to the station.
6.
Green "power on" light: comes on when power is being supplied to the switch box.
7.
Green "station operating" light: comes on when the station is functioning and goes off if the two
turbines have come to a stop normally or if a pressure fault occurs lasting more than 1 minute.
8.
Orange "malfunction" light: comes on if turbine A or B develops a problem, in one of the following
situations:
The current to the primary turbine has been lost,
The temperature at the primary turbine exhaust is unusually high and has triggered the temperature
breaker. This fault triggers the malfunction light if it lasts for at least 30 seconds,
The pressure has not reached the low-pressure alarm setting following a 1-minute delay after the primary
turbine has been started (see § 2.5.3 for setting information on the MILLENIUM system).
When the primary turbine causes one of the malfunctions described above, the auxiliary turbine will cut in.
9.
Red "pressure fault" light: comes on when the pressure level does not reach the default vacuum
pressure level following a 2-minute delay after the primary and auxiliary turbines have been started.
This light comes on if the pressure exceeds the high-pressure alarm setting (see §2.5.3) after a 1-minute delay.

The carry-over voltage-free contact
A general alarm change-over contact (5 – 6 - 7) can be carried over remotely.
This contact is provided for 250 Vac maxi tension and 6A maxi intensity.
This contact is switched when a fault occurs:
Voltage is present,
Loss of current to turbine A or B,
A or B temperature breaker,
Pressure.
An NC contact (10 - 11) is linked to the orange "malfunction" light.
An NC contact (8 - 9) is linked to the red "pressure fault" light.

How the MILLENIUM system operates
Alarms management
Line n°1: control pressure in mbar.
Line n°2: "Gas Evac Ready"
waiting for the turbines to be activated.
"turbine : A" or "turbine : B" or "turbine: A B"
Line n°3: "manual mode"
when the switch is on manual mode
Or "** ALARM **"
if an alarm has been activated.
Line n°4: shows either :
● current alarms
● parameters
If an alarm has been activated, "** ALARM **" will appear
on line 3.
Line 4 will then show the type of alarm that has been
generated, in sequence:
Power loss A: electrical current to the turbine
has been lost,
Temperature breaker A: The temperature
breaker for turbine A has been triggered. The
fault will disappear automatically.
Power loss B: electrical current to the turbine
has been lost,
Temperature breaker B: The temperature
breaker for turbine B has been triggered. The
fault will disappear automatically.
Low press.: the pressure in the system is below
the low-pressure alarm setting. Hysteresis: 20
mbar.
High press.: the pressure in the system is higher
than the high-pressure alarm setting.
If no alarm has been activated: "condition OK"
will be displayed on line 4
