• Includes a relative-time clock

The Battery Manager communicates with
the main processor via a serial data
channel. The main processor issues
commands to the Battery Manager which
then responds with status information and
data using this channel.

1.6.1 Fan

The internal fan is used for cooling, mainly
to help prolong battery life. It is a ball­bearing, brushless DC fan. The fan is
always on when the battery is charging with
"Fast" or "Top-up" charge. The fan will go
on any time battery temperature is over
22°C.

1.6.2 Battery and Charging Process

The battery is a ten-cell (1.2V per cell), high
capacity nickel-cadmium type rated at
12 volts and 1.8 amp-hours (with a minimum
of 500 charge cycles).

The battery pack (10 to 18V) has a built-in
temperature sensor which allows the Battery
Manager to monitor the temperature of the
battery. The pack also includes a
temperature-limiting thermostat which opens
the circuit if the battery temperature gets too
hot and closes again when the temperature
returns to normal.

1.6 BATTERY MANAGEMENT SYSTEM

1.6.2 Battery and Charging Process

(Continued)

The battery charge circuit charges the
battery with a constant current of 1 ampere
whenever the Battery Manager turns the
charger on. The Battery Manager regulates
average charge current by turning the
charger on and off with the appropriate duty
ratio. The battery charge cycle consists of
four modes; fast charge, top-up charge, float
charge, and hot charge.

• Fast Charge

: Fast charge is initiated
whenever the battery is less than 36°C,
and has been discharged by more than
200 Ampere-seconds through actual use
or self discharge. Leaving the instrument
unplugged for a day would cause about
200 Ampere-seconds of self discharge.
The charge current is a continuous
1 Ampere. The end of a fast charge is
detected when the temperature of the
battery rises 7°C above its temperature
at start of charge and is at least 30°C, or
when the battery voltage declines by
192mV below its peak value, or total
charge time exceeds 3.2 hours. Refer to
“Battery Charge Regulator” section in the
“Principles of Operation” chapter for
further details.

•T

op-Up Charge: The top-up charge
phase begins at the end of the fast
charge phase and finishes adding the
last few percent of charge to the battery
and balances individual cell charges.
This phase charges at an average rate of
180 mA (1 A for 0.9 seconds every 5
seconds) for 180 minutes. At that time,
the instrument will go into float charge
mode.

The charger will suspend top-up if the
battery temperature exceeds 37°C. The
time spent to cool down to below 37°C is
in addition to the 180 minutes top-up
charge time. If top-up cool down time
exceeds 5 1/2 hours, the instrument will
go into float charge mode.

• Float Charge

: The float charge phase
begins at the end of the top-up phase
and helps maintain a fully charged
battery. This phase charges at an
average rate of 40 mA (1A for 0.2
seconds every 5 seconds). The fan
remains on or turns on when battery
temperature exceeds 22°C.

• Hot Charge

: The hot charge mode occurs
when the instrument determines that the
battery is >36°C (normally due to
ambient temperature being >27°C) to
allow a charge after waiting 3 hours for it
to cool down. Hot charge mode charges
at an average rate of 180 mA (1A for 0.9
seconds every 5 seconds) for a total
charge time of 18 hours. If the battery
temperature exceeds 43°C, the charging
is turned off until the temperature falls
below 43°C.

Note that the cool down time is in
addition to the 18-hour charge time. The
float charge cycle begins at the end of
the hot charge cycle.

1.6.3 Refresh Cycle

A battery refresh cycle performs a full
charge, discharge, and recharge to
condition and measure the capacity of the
battery. This refresh results in a new
"Measured Capacity" in the battery
diagnostics and can be used to judge the
condition of the battery.

1.6.3 Refresh Cycle (Continued)

The refresh cycle must be initiated

capacity is loaded and the OK soft key is
pressed, the original rated capacity must be

The empty ("E") icon will flash during the
discharge part of the refresh cycle (see
Figure 1-1). Important: The AC power must
remain connected and uninterrupted during
the discharge cycle. If the AC power is
removed during this cycle, the discharge
cycle will be terminated and another refresh
cycle will have to be initiated. The time for
complete refresh is dependent upon battery

temperature and takes an average of 20
hours to complete (refer to Figure 1-1).

Two ways to initiate a manual refresh cycle
are:

• Disconnect from AC, unplug battery, and
then press power switch. Lower LCD
will go blank. Reconnect battery and
then reconnect instrument to AC.

• Enter Diagnostics Mode, go to page D2,
Select Battery Status, and enter 0.0 Ah
for battery-rated capacity. Press Enter
and ok. Turn instrument off and back on,
and then reconnect to AC. Once the fan
turns on (indicating start of a refresh
cycle), return to page D2 and reset
battery rated capacity to 1.3 Ah.

1.6.4 Battery Gauge

The battery gauge provides an indication of
the approximate amount of charge
remaining on the battery. It will usually
indicate less charge than is actually
available with a new battery. This is
displayed in a bar graph format on the
lower LCD Display and is active as long as
the battery is connected to the instrument.
(Refer to Figure 1-2, Lower LCD Display
Layout.)

The battery gauge circuitry measures the
current flow into and out of the battery and
maintains a record of the state of charge of
the battery. This record is reset each time
the instrument completes a full refresh
cycle. The battery gauge uses this record,
together with a measurement of the present
power requirements of the instrument, to

estimate the charge available on battery
power at the current infusion rate.

NOTES:

• The instrument label and battery gauge
are always displayed, even when the
instrument is turned off; however, the
battery gauge does not represent the
battery charge remaining when the
instrument is turned off.

• To ensure a more accurate battery gauge
reading, review the battery gauge five
minutes after starting an infusion. The
gauge updates for each program change
while infusing. Battery run time may be
affected by the operating mode, rate,
monitoring options and back pressure.

1.6.5 Power On/Off

The Battery Manager provides the interface
between the power on/off switch(es) and
the main processor. When the instrument
is off, the Battery Manager interprets either
power switch as a turn on command and
applies power to the rest of the instrument,
informing the main processor which switch
was pressed. Once power is on, further
presses of a power switch are passed on to
the main processor which determines the
appropriate response under the existing
conditions. If the response is to turn the
power off, the main processor requests that
the Battery Manager remove power from
the rest of the instrument.

If an error has been detected which causes
the watchdog to be in alarm, pushing the
power switch (or for dual channel
instruments, either power switch)
immediately causes the power to be turned
off, without intervention by the Battery
Manager.

1.6 BATTERY MANAGEMENT SYSTEM

(Continued)

1.6.6 Lower LCD Display

The Battery Manager also contains the
driver for the Lower LCD Display. In addition
to the battery gauge, this display contains a
four-character alphanumeric "configuration"
display and several icons. The information
for these other displays is controlled by the
main processor and is communicated to the
Battery Manager through the serial channel.
The Battery Manager also uses the four­character display to indicate errors detected
in the Battery Manager system itself.

1.6.7 Clock

The Battery Manager provides a "relative
time" clock which the main processor can
set and read. This clock consists of a 32-bit
counter which is incremented once a
second under all conditions. The main
processor uses this counter as a means of
determining elapsed time even when power
has been turned off. The clock is used to
compensate for normal battery capacity
degradation over time.

1.6.8 Battery Maintenance

Several features have been included in the
Battery Manager to help properly maintain
the battery.

• A battery capacity measurement is
available in diagnostic mode.

• A special circuit removes all load from
battery when voltage falls too low,
preventing damage from over discharge
due to long-term storage.

NiCad batteries can be stored indefinitely
with no load but will self-discharge from a
charged state in about 100 days. This does
not damage the battery as it would if it were
a lead acid-type battery. Connect
instrument to AC to recharge batteries.

Figure 1-2. Lower LCD Display Layout

• Use only batteries approved by ALARIS
Medical Systems, due to Battery
Manager requirements and the
thermostat contained in the battery
assembly. If the instrument has been in
storage, connect it to AC power before
turning it on. Usually one refresh cycle
is sufficient to restore battery capacity.
If necessary, repeat the procedure at
24-hour intervals, 2 or 3 times, to
increase capacity.

• Battery replacement should be
performed by qualified service
personnel while instrument is not in use.
DO NOT open, incinerate or short circuit
the battery. Worn-out batteries must be
disposed of properly, according to local
regulations.

NOTE: If under load (inside instrument), the

maximum storage time would be about 130
days before electrolyte extrusion occurs past
the battery seal.

If the battery exhibits short run times, a
reconditioning procedure can be used:

1. Disconnect battery and AC

2. Press On/Off switch and verify lower
LCD goes blank.

3. Reconnect battery.

4. Reconnect instrument to AC. A refresh
cycle will be initiated.

5. Repeat this procedure at 24-hour
intervals, 2 or 3 times, to increase
capacity or use a battery conditioner.

1.7 NICAD BATTERY CAPACITY
INFORMATION

All batteries have specific conditions under
which they are guaranteed to meet their
published specifications. Deviations from
these conditions typically result in a
reduction of available capacity.
Manufacturers of NiCad batteries rate
capacities, usually expressed in Ah, based
on a specified "ideal" charge and discharge
condition, as well as the use of a "new"
battery. Battery manufacturers do not use
the calendar year for battery date codes.
The battery date code year starts on
September 1. The first two digits of the date
code are for the year and the last two digits
are for the week of the year (for example,
date code 0411 = the year 2004 and the
eleventh week from September 1).

An ideal charge cycle starts with a fully
discharged battery charged at C/10 (C is the
rated capacity in Ah) constant current for 15
hours while at room temperature. For
instance, a 1.8Ah battery would be charged
for 15 hours at 180mA constant current with
a room temperature of 23°C.

The ideal discharge starts with a fully
charged battery under a C/5 constant
current load at room temperature,
discharging to a cell voltage of 0.9V. The
rated capacity is then calculated as the time
to discharge divided by 5. Again, a 1.8Ah
cell would be discharged at 360mA constant
current and not reach 0.9V for at least 5
hours. Note that a given battery type has
different capacities based on the load. For
instance, a battery rated at 1.8Ah at a
360mA load may have only 1.6Ah at a
1600mA load.

As can be seen from the preceding ideal
conditions, there are many conditions which
can affect the battery capacity. The
following conditions have the most practical
impact on battery capacity delivered in this
instrument.

•T

emperature During Charge:
As the effective ambient temperature of
the battery increases, the amount of
charge that the battery will accept is
decreased. At an ambient temperature of
35°C, an enclosed battery will
temporarily accept only about 90% of the
charge it would otherwise accept at
23°C. Because the batteries are internal
to the instrument case and the instrument
itself generates heat, the batteries will be
exposed to temperatures above room
temperature. Some of the ways the
instrument limits the temperatures that
the battery sees include forcing air
across it (an internal fan) and turning off
the charger when the battery temperature
gets too high.

1.7 NICAD BATTERY CAPACITY
INFORMATION (Continued)

• Cycle Life and

Aging:
As batteries get older and go through
many charge/discharge cycles, batteries
"wear out," in that the chemicals and
materials used to construct the cell break
down. The way the instrument deals with
this is to assume that a battery will
continually reduce capacity at a rate
equivalent to 30% over 4 years, and
continually reduce capacity at a rate
equivalent to 30% per 200 full charge
cycles. These calculated values are
used to reduce the displayed runtime on
the battery gauge.

• Partial Discharge/Charge:
When a battery is partially discharged,
then charged for less than the full time,
differences between individual cell
capacities result in cells completing
charge at different times. If the full
charge sequence is not then completed,
the cell "mismatch" becomes
progressively greater. This is viewed by
the user as low apparent runtimes and
premature low battery warning and
alarms.

The problem is cumulative in that the
mismatch increases for every partial
cycle. The lowered capacity is not
permanent, but may require 2-3 full
charge cycles to recover. The way the
instrument deals with this is to reduce the
displayed runtime based on a limited
history of partial cycles.

• Charge Rate:
The ideal charge rate requires 15 hours
to get to full charge, which is undesirable
from the user's perspective. The
instrument provides a multiphase charge
cycle which results in about 80% capacity

in the first 2 hours after fast charge. The
next charge phase, top-up, is designed to
finish the charge and to bring all
individual cells to the fully charged state,
essentially rematching them. Refer to
“Battery and Charging Process” section
in this chapter for “Fast Charge” and
“Top-up Charge” information. If the
top–up charge is not completed, then the
cell mismatch is not reduced and the
cumulative capacity reduction occurs.
Top-up is a 3-hour charge, but the
elapsed time to complete it may be over
5 hours, as the charger is turned on and
off to keep the battery cool during that
time.

• Battery

Alarm Voltage:
The battery alarm voltage is the voltage
at which the instrument stops operating
and generates an alarm indicating the
instrument needs to be connected to AC
power. As noted in the ideal discharge
condition, the end of discharge is
determined by 0.9V/cell.

Under perfect conditions, a battery of 10
cells connected in series would reach the
end of discharge at 9.0V; however, cells
are not perfectly matched so some will
reach 0.9V before others. The problem
occurs when a cell in series with other
cells can go below 0.9V and actually can
go into cell reversal, which permanently
damages the particular cell. On the other
hand, increasing the alarm voltage to
compensate for imperfectly matched cells
results in reduced runtimes with available
capacity.

1.7 NICAD BATTERY CAPACITY
INFORMATION (Continued)

The user sees this as premature low
battery warnings and alarms. The way
the instrument deals with this is to
increase the alarm voltage to guarantee
the battery is not damaged and to reduce
the assumed capacity to below that
printed on the battery. The battery gauge
is intended to show the minimum run
time left on the battery taking all these
factors into account.

NOTE: In the event ALARIS Medical Systems
provides different battery packs in the future,
the replacement battery may have a different
rated capacity. Therefore, the Battery
Manager of the instrument needs to know that
a new battery has been added and the rated
capacity has changed. Refer to the
“Removing Battery” section of “Corrective
Maintenance” chapter and the “Changing
Rated Capacity of Battery” section of
“Troubleshooting” chapter.

1.8 DYNAMIC MONITORING®SYSTEM
(DMS)

The following is general information
regarding the Dynamic Monitoring

®

System.

In order for fluid to move through the
administration set, a pressure difference
(gradient) must exist. In a gravity setup, this
is done by head height. In a pump, the
instrument will develop pressure to
overcome downstream effects on fluid flow.

The fundamental concept behind the
Dynamic Monitoring

®

System is that the
resistance to fluid flow from the mechanism
to the patient's infusion site can be
measured. This is done by intentionally
varying the flow rate while monitoring the
resulting changes in fluid pressure (refer to
Figure 1-3 "Resistance Graph"). Signal

processing of the pressure and flow data
can then produce the fluid impedance value.
Such measurements can be made
continuously at short intervals and be
independent of the selected rate. Head
height and resulting pressure variations,
likewise, will not affect the measurement.

When a complete occlusion occurs, the
resistive part of the fluid impedance is very
large (theoretically infinite). Elevated
resistances due to clotting, clogged filters,
partial occlusions or infiltrations can be
measured.

The Dynamic Monitoring

®

System provides
a means to measure the mechanical
properties of the downstream flow path.

Features include:

• Alarm setting is based on dynamic
system impedance (pressure changes,
not absolute pressure).

• Detection of complete occlusions.

• Reduced nuisance alarms by minimizing
artifact effects such as head height and
patient movement.

• AutoRestartPlus feature allows
instrument to automatically continue
operation if an occlusion is cleared within
self-check period (40 seconds). A
warning tone and “Checking Line”
message will occur for up to 40 seconds.
The feature can be turned off (set
restarts to zero), or number of restarts
may be set from 1 to 9.

NOTES:

• The restart counter is reset whenever
Run/Hold is pressed, the instrument or
channel is turned off or an alarm occurs.

• When infusion is started, the resistance
may be other than 0%, depending on
solution viscosity, catheter/tubing size and
filters.

• Resistance Alert provides an early
warning of slow or gradual changes in
resistance of IV line/site. Resistance Alert
marker can be set from 5 to 100%. It
allows resistance to be monitored and
provides a tone every 30 seconds if
percent resistance exceeds resistance
alert mark.

• Resistance display may be turned off. If
off, system continues to monitor
downstream resistance and alarm
appropriately.
