12.2.1 Power supply management
The supply board manages the energy source changeover automatically according to the hierarchy as
follows:
1.
Mains supply;
2.
In the event of failure, power supply from external battery;
3.
In the event of failure, power supply from internal battery.
12.2.2 Mains supply
Two pictograms indicate whether or not the mains power supply is present.
Mains present
Mains absent
12.2.3 Internal battery
In the event of absence of the mains and the external source, the switch to internal battery is indicated
by a low-priority acknowledgeable alarm “Ventilator operates from internal battery!”.
The charge status of the internal battery is then indicated in the upper left-hand part of the screen (ex-
ample based on a new battery):
Full battery charge
Comfortable battery charge
Medium battery charge
Battery low - connect the unit to the mains power supply.
Associated with a medium-priority acknowledgeable alarm “Internal battery nearly dis-
charged!”
Battery dangerously low - imminent shutdown
Associated with high-priority acknowledgeable alarms “Internal battery discharged!!!
Connect AC power” and then “Internal battery inoperative!!! Connect AC power”
It is then urgent to connect the ventilator to the mains or to an external battery to prevent
it from shutting down due to a lack of power.
When the unit is connected to the mains or an external battery, the unit’s internal battery recharges. A
special pictogram appears on the screen to show the progress of light segments (example based on a
new battery):
Battery discharged
Battery half-charged
Battery fully charged
