1.1 INTRODUCTION
This manual covers Signature Edition versions with
software 2.44 and higher and is the initial release of
the 7101A/7201 version. Series includes 7100F,
7200F, 7100G, 7200G, 7101A and 7201A. 710X
means 7100 and 7101 iterations.
There are two specific model groups —
7100G/7200G and 7101A/7201A. The key
differences are:
HARDWARE — The 7101A/7201A Series is labeled
for 220V with two power cord options and has
isolated RS232 Board, potential equalization (PE)
connector, drop sensor board installed. There is no
Nurse Call option. The keypad has symbols instead of
words.
SOFTWARE — The 7101/7201 Series has no drug list
(Drug ? only), some defaults are different in
configuration mode and there are seven (7)
languages to choose from.
The IVAC Signature Edition system includes the
SE I — Model 710X, and SE II — Model 720X
Volumetric Infusion Pumps and AccuSlide™
administration sets.
Refer to the Directions for Use manual for complete
information regarding the setup and operation of
the pump.
The Model 7100/7200 Series pump is a 100-240
VAC, 50/60 Hz instrument family that supports both
single and dual channel fluid delivery. Each
instrument carries identification labels designating its
model and serial number.
The pump features user-interactive software. It
displays prompts, alarms and alert messages, and
troubleshooting information on the main LCD display
of the instrument. The pump can be configured to
your specific operational requirements and allows
upgrades for future product enhancements. The
pump has been designed to interface with accessory
equipment including nurse call system and/or
computer monitoring system.
This manual contains instructions for maintenance,
repair, and configuration of the instrument. The
maintenance and repair sections of the manual are
written for personnel experienced in the analysis,
troubleshooting, and repair of analog and digital
microprocessor-based electronic equipment.

1.3 Battery Management System
This section contains general information on the
battery management system. Included is information
on how the Battery Manager monitors and maintains
the battery, controls the power on/off for the rest of
the instrument, and provides support functions for
the main processor. Refer to Chapter 4 for more
detailed functional descriptions.
The battery management system consists of 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 the battery charger
•Provides a battery status “battery gauge“
•Monitors voltage and temperature of battery
•Controls the instrument power source (on/off
function)
•Drives the Lower LCD Display (See Figure 1-1)
•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.
1.3.1 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 battery is charging with
“Fast”or “Top-up”charge. The fan will go on any
time battery temperature is over 22°C.
1.3.2 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/discharge
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.
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.
a. Fast Charge: Fast charge is initiated whenever the
battery is less than 36ºC, 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 7ºC above its temperature at start
of charge and is at least 30ºC, or when the
battery voltage declines by 192mV below its peak
value, or total charge time exceeds 3.2 hours. Also
refer to Battery Charge Regulator section (4.5.3)
for further details.
b. Top-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 (1A
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 37ºC. The time
spent to cool down to below 37ºC 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.

1-6 IVAC®Signature Edition™Technical Service Manual
GENERAL INFORMATION
M EDICAL S Y S TE M S
™
c. 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 (1 A for 0.2 seconds every 5
seconds). The fan remains on or turns on when
battery temperature exceeds 22ºC.
d. 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.

1.3.3 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. The refresh cycle must be initiated manually,
either by disconnecting/reconnecting the battery or
by loading 0.0 A-H as the rated capacity in the
battery diagnostics page. After the zero rated
capacity is loaded and the OK button is pressed, the
original rated capacity must be reloaded to preserve
the battery gauge. The empty “E”icon will flash
during the discharge part of the refresh cycle. 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.
Two ways to initiate a manual refresh cycle are:
1. Disconnect from AC, unplug the battery, then
press the power switch. The lower LCD will go
blank. Reconnect the battery then plug the pump
into AC.
2. Enter Diagnostics Mode, go to page D2, and enter
0.0 Ah for battery rated capacity. Press Enter and
ok. Turn pump off and back on, then plug the
pump into AC. Once the fan turns on (indicating
the start of a refresh cycle), return to page D2 and
reset the battery rated capacity to 1.3 Ah (with
battery manager software 3.01 and higher).
1.3.4 Battery Gauge
The battery gauge provides an indication to the user
of the approximate amount of time the instrument
will run on battery power. It will usually indicate less
run time than the user will actually get on 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. The display
indicates up to 4 hours in 15 minute increments.
(See Figure 1-1, 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 pump 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 time
available on battery power at the current infusion
rate.
NOTE: When the instrument is turned off, the gauge will
indicate approximate run time for infusions of 125 ml/hr.

1.3.5 Power On/Off
The Battery Manager provides the interface between
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, a push of either power
switch will immediately cause the power to be
turned off, without intervention by the Battery
Manager.
1.3.6 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.
Figure 1-1 Lower LCD Display Layout
1.3.7 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 determine
when a battery refresh cycle is required as well as
compensating for normal battery capacity
degradation over time.
1.3.8 Battery Maintenance
CAUTION: Use only ALARIS™Medical approved
batteries due to Battery Manager requirements and
the thermostat contained in the battery assembly.
Connect pump to AC before turning pump on if it
has been in storage. 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.
Several features have been included in the Battery
Manager to help properly maintain the battery.
•A measurement of the capacity of the battery is
available in the diagnostic mode.
•A special circuit removes all load from the battery
when the voltage falls too low, preventing
damage from over discharge due to long term
storage.
NiCd 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.
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. Disconnect
battery and AC, press the On/Off switch and verify

instrument into AC. A refresh cycle will be initiated.
Repeat this procedure at 24 hour intervals, 2 or 3
times to increase capacity or use a battery
conditioner.
CAUTION: Dispose of or recycle battery following
hospital protocol. Refer to your institution’s operating
procedures, your state’s EPA guidelines for disposal of
battery or contact Rechargeable Battery Recycling
Corporation (RBRC) at 1-800-822-8837.
1.4 Nicd 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 nicd batteries rate capacities,
usually expressed in Ah (Ampere-Hours), based on a
specified “ideal“charge and discharge condition as
well as the use of a “new”battery. Battery
Manufacturer’s date codes start on 9/1 of the
upcoming year (e.g. date code 9611 = first week of
November 1995).
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.
a. TEMPERATURE 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. Since the batteries are internal to
the instrument case, they will be exposed to
temperatures above room temperature since the
instrument itself generates heat. 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.
b. 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 discharge/charge
cycles. These calculated values are used to reduce
the runtime displayed on the battery gauge.
c. PARTIAL DISCHARGE/RECHARGE - 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 discharge/charge cycles to recover.
The way the instrument deals with this is to
reduce the runtime displayed based on a limited
history of partial cycles.

IVAC®Signature Edition™Technical Service Manual 1-9
GENERAL INFORMATION
M EDICAL S Y S TE M S
™
d. 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 Section
1.3.2 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.
e. BATTERY ALARM VOLTAGE - The battery alarm
voltage is the voltage at which the instrument
stops operating and generates an alarm to tell the
user to plug it into AC line. 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. 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 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 future, ALARIS Medical Systems may provide
different battery packs. 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 Section
5.3 “Replacing Battery”and Section 6.4.6, Changing Rated
Capacity of Battery.
1.5 Dynamic System Monitoring™ (DSM)
The following is general information regarding the
Dynamic Monitoring™system as it relates to the
Signature Edition instrument.
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 1-2
“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.
Pressure = Effect when a force is against a restriction.
Resistance = Cause when impediment to fluid flow occurs.
Resistance = Change in Pressure (∆P)
Change in Flow (∆F)
Refer to Figure 1-3 “Pressure and Resistance Graph”.
