Battery Modules - Maquet SERVO-s Service Manual

Service procedures SERVO-s Ventilator System
The life span for the Battery module is calculated
to two and a half year from manufacturing date.
Normal time for logistics and storage are
included in this calculation. The calculation
corresponds thus to an estimated operational
time of two years. Manufacturing date (year-
week) is printed on the battery label.

Battery modules
System SW version V2.01.00 (or higher) includes an
improved monitoring of the battery status. Select
'
Status / Batteries' on the User Interface to check
battery status. Refer to the illustrations below.
On ventilators with this improved battery monitoring,
the batteries condition and capacity are verified
during the Pre-use check and also continuously
during operation of the unit. No further functions
checks of the batteries are required.
With this improved battery monitoring, the Battery
status window shows:
. Usable backup time
.
Calculated as the sum of the
estimated backup time for the connected Battery
modules reduced with 10 minutes as an extra
safety feature.
. Slot number
.
Note that slot 1 is the lower slot and
slot 2 is the upper.
. Battery module S/N
.
. Charge indicator for each battery
,
where:
0 boxes filled = < 10% relative charge
1 box filled = 10-25% relative charge
2 boxes filled = 26-50% relative charge
3 boxes filled = 51-75% relative charge
4 boxes filled = 76-100% relative charge
Recharge time for a discharged battery is approx.
3 hours/battery. If a battery is fully discharged, e.g.
due to long storage time, it may require up to 12
hours charging time.
With the charge status indicator on the User
Interface, the four green LEDs on the Battery
module are no longer required and will be removed
from the modules.
. Remaining operating time in minutes for each
battery.
Furthermore, an activity instruction, displayed
directly next to the operating time, may show:
. Expires soon
.
Message activated if expiry date will
be reached within 60 days.
. Replace battery
.
The battery must be replaced and
discarded. Message activated if:
-
The batteries expiry date is passed and its life
span is exceeded. Note: Due to the age of the
battery, the calculated backup time may in this
case not be reliable. Even if the battery indicates
a significant backup time, the battery must be
replaced.
or
-
The batteries operational capacity is too poor for
continued usage, caused e.g. by the chemical
process in an aging battery.
