the Battery Manager IC and various sensors

and signal processing circuits. The Battery

Manager IC (Rev. 3.06) is a custom-

programmed microcontroller that performs

the following functions:

• Controls battery charger

• Provides a battery status "battery gauge"

• Monitors voltage and temperature of

battery

• Controls instrument power source (on/off

function)

• Drives Lower LCD Display

(refer to Figure 1-2)

• 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 ball-

bearing, 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

(Continued)

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.

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.

(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 four-

character 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.

MNTR

GOLD

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.

1.6.8 Battery Maintenance (Continued)

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,

• 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

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.
