Maintenance:
●Observe the maintenance intervals. Batteries are wearing parts. The
replacement intervals depend on the utilization.
During operation:
●Observe the ambient conditions (see "Technical data", page 11).
●After battery operation, connect the device to the mains power supply. Fully
charge the batteries. Observe the required charging time.
●Avoid shocks and vibrations.
●Use the battery tests to check the capacity of the batteries on a regular basis.
The batteries must have sufficient capacity. Replace the batteries if necessary.
During storage:
●Storage at an increased ambient temperature reduces the life span of the
batteries. The storage duration must not be exceeded. Observe the following
information: "Technical data", page 11.
●Always fully charge the batteries.
●After 5 days at the latest, connect the device to the mains power supply. Fully
charge the batteries. Observe the required charging time.
If recharging is not possible after 5 days at the latest, do the following:
●Turn off the main switch and then unplug the power plug.
✓The device is then in the energy-saving mode, and the discharge is reduced
to the self-discharge of the batteries.
Before using on the patient:
●Check that the capacity of the batteries is sufficient. The batteries may be deeply
discharged or faulty as a result of excessively long storage.
7.2.2 Battery test
To determine the current state of the batteries, a battery test is possible at regular
intervals. The battery test determines the approximate operating time.
The battery test consists of a charge-discharge-charge cycle. After the batteries
have been fully charged, the device is operated in test mode with power supply
from the batteries. The determined operating time is the approximate operating time
to be expected in the next period of battery operation with typical ventilation without
the GS500 gas supply unit.
Dräger recommends the following test intervals:
Operating time
The following table shows the expected typical operating time due to the ageing of a
new battery without operation with an activated gas supply unit GS500.
If the batteries do not correspond to the approximate operating time listed,
replacement of the batteries is recommended.
Internal battery (NiMH) Every 3 months
PS500 power supply unit (VRLA) Every 3 months
Power supply unit PS500 (LFP) Every 3 months

Supplement | Evita V series / Babylog VN series 9
Service
The operating time may be reduced due to the utilization of the battery. The data
are approximate values and cannot be regarded as guaranteed for every battery,
Replace the batteries if the operating time falls below the minimum value (see
"Battery ageing", page 15) or after 24 months.
The figures are based on the assumed following average battery usage:
– Applies to the internal battery without using the GS500:
400 battery discharges of up to 15 minutes per discharge during device
operation with the internal battery over a time period of 2 years.
This corresponds to a monthly usage of approx. 16 discharges of up to
15 minutes per discharge.
This corresponds to a weekly usage of approx. 4 discharges of up to
15 minutes per discharge.
– Applies for PS500 without use of the GS500:
400 battery discharges of up to 90 minutes per discharge during device
operation with the PS500 over a time period of 2 years.
This corresponds to a monthly usage of approx. 16 discharges of up to
90 minutes per discharge.
This corresponds to a weekly usage of approx. 4 discharges of up to
90 minutes per discharge.
The battery lifespan is shortened if the battery is discharged more frequently or for
longer than 90 minutes (PS500) or 15 minutes (internal battery). This can lead to a
deviation from the maximum operating time specified in the table above.
A discharge is defined as the usage and subsequent charging of the battery.
Preparing the battery test
The battery test can be performed independently of the operating status of the
device. If a patient is being ventilated, note the charge status indicator.
Prerequisites for the battery test while a patient is being ventilated:
– The device is connected to the central gas supply system.
– The device is connected to the mains power supply.

9 Principles of operation
9.1 Battery concept
9.1.1 General information
At the time of manufacture and delivery, batteries have a typical capacity which is in
accordance with the information specified in the battery manufacturer's data sheet.
The electrochemical composition of the battery is crucial for its total capacity. The
battery runtime is derived from this information (see "Technical data", page 11).
The capacity of batteries changes with increasing age and utilization.
All the following information and specifications refer to perfectly functioning
batteries. If batteries are faulty, the correct device function, e.g. battery charge
indication or alarms, may be impaired (see "Battery test", page 8).
9.1.2 Battery charge indication on the screen
The charge status indicator shows the available battery charge determined by the
electrochemical processes. When the batteries are, e.g., fully charged, this state is
indicated by a corresponding symbol.

8.2 Operating characteristics (continued)

Supplement | Evita V series / Babylog VN series 15
Principles of operation
The charge status indicator is a relative indication which is based on the
electrochemical properties of the battery. The charge status indicator is evaluated
on the basis of a battery model.
The use of a model-based indication is a state-of-the-art technique which finds
application in many fields, e.g., computers, cellular phones, etc.
The model-based indication of battery charge takes account of the following
information, among other things:
– Type of battery (e.g., NiMH, VRLA, or LFP)
– Maximum capacity on delivery (e.g., 12 Ah)
– Age of the battery (e.g., new or 2 years)
– Capacity spent (irreversibly lost) over the utilization time (e.g., 1000 Ah)
– Device power consumption (e.g., 2.5 A)
– Discharging mode
– Charging mode
If the power consumption changes, e.g., due to switching to standby mode,
operation of a GS500 gas supply unit, or after adjusting the screen brightness, the
remaining battery runtime of the device also changes. The charge status indicator is
updated to take account of the power consumption.
In accordance with the specification, the charge status indicator is only displayed
and updated after the device has been completely started up. This procedure may
take a few minutes.
9.1.3 Battery ageing
The electrochemical composition of a battery alters as a result of ageing and
utilization. Consequently, every battery loses a proportion of its maximum capacity
when compared to the maximum capacity of the battery in its new condition. This
loss of capacity is typically irreversible.
As a result of ageing and utilization of the battery, there is a change in the actual
maximum battery runtime which cannot be displayed by the percentage values in
the charge status indicator. The percentage value refers to the battery charge,
which entails a different operating time depending on the age of the battery, for
example.
Symbol Battery charge
99 to 100 %
75 to 98 %
50 to 74 %
25 to 49 %
0 to 24 %, flashes red.
Batteries faulty or no information available on the battery charge.

16 Supplement | Evita V series / Babylog VN series
Principles of operation
New batteries
The following data for minimum battery runtime apply to new and fully charged
batteries. The symbol for a fully charged battery is displayed (see "Battery charge
indication on the screen", page 14). For further information see: "Technical data",
page 11. Owing to production fluctuations during the manufacture of batteries, the
battery runtime can be considerably longer.
Aged batteries, e.g., 2 years old
The following data for the minimum battery runtime apply, e.g., to 2-year old and
fully charged batteries. The data are approximate values and cannot be regarded
as guaranteed for every battery, The symbol for a fully charged battery is displayed
(see "Battery charge indication on the screen", page 14). For further information
see: "Technical data", page 11.
When the internal battery and the batteries in the PS500 show less than the
following minimum battery runtimes, they are considered to be spent.
A reduction in the capacity of batteries due to ageing and utilization is normal. As
a greatly simplified approximation, an average linear reduction in capacity can be
assumed. The current individual capacity of a battery depends on the following
factors, among others:
–Age
– Utilization (frequency, duration, and power consumption)
– Battery charge
– Ambient temperature
9.1.4 Alarm behavior during battery operation
The switch-over of the device to battery operation is indicated by the Battery
activated alarm (see "Alarm – Cause – Remedy", page 6). The alarm can be
acknowledged by the user. Consequently, the Battery activated alarm will no
longer be displayed until the mains power supply is re-established.
When the device is equipped with a PS500 power supply unit, in battery operation
the PS500 is discharged first. If the mains power supply has not been re-
established, the device switches over to the internal battery after the battery runtime
of the PS500 has elapsed. The switch-over is indicated by the Internal battery
activated alarm.

Supplement | Evita V series / Babylog VN series 17
Principles of operation
At the end of the battery runtime of the internal battery, the device issues the
Battery low alarm. The Battery depleted alarm follows after that.
These alarms appear at the time specified by the model-based calculation for the
particular battery.
Schematic representation of the sequence of alarms
The schematic representation of the sequence of alarms with respect to battery
utilization is shown in an example with a PS500 but without the use of a GS500.
The representation corresponds to the battery runtime of new and fully charged
batteries.
When the voltage drop of the internal battery reaches an operationally critical value,
a shut-down of the device due to an inadequate supply is imminent. In this case, the
power supply failure alarm sounds.
If the device displays the Battery low alarm message or the Battery depleted
alarm message, connect the device to the mains power supply.
When the remaining calculated battery runtime is less than 10 minutes, the
model-based Battery low alarm appears. When the remaining calculated battery
runtime is less than 5 minutes, the model-based Battery depleted alarm appears.
The remaining battery runtime after the corresponding alarms can be
considerably longer than the specified minimum battery runtime.
When the device is fitted with the GS500 gas supply unit, the device calculates
the time for the Battery depleted alarm allowing for the power consumption of a
GS500, regardless of whether the GS500 is activated or not.
