Instructions for use Primus Infinity Empowered SW 4.5n
Power failure
Primus Infinity Empowered automatically switches
to the built-in uninterruptible power supply UPS. In
this case, the auxiliary outlets will not be supplied
with power.
Provided that the battery is fully charged, operation
can be continued with the current settings for at
least 30 minutes (up to 90 minutes, depending on
the ventilation parameters).
The message POWER FAIL (A) and the remaining
battery capacity in percent (B) are displayed on the
screen.
Example:
If the battery is almost empty, the message
BATTERY LOW is displayed.
Primus Infinity Empowered permits manual ventila-
tion with 100 % O
2 in the event of a power failure
and empty batteries. The fresh-gas mixer, ventila-
tor, and monitoring are inactive.
If all electrical power fails, all individual settings, in-
cluding alarm limits which are not saved in the de-
fault settings, will be lost.
When the power supply is re-established, the an-
esthesia machine behaves as described in "Venti-
lator and fresh gas delivery failure" on page 191;
see also the alarm message GAS + VENT. FAIL on
page 200. To continue operation for emergency sit-
uations, switch the anesthesia machine off and
then on again and refer to page 89 of these instruc-
tions for use.
