Operating on Battery Power
The pump operates on battery power when it is disconnected from the AC power. The battery power indicator, the
Information and Numeric Displays will flash whenever the pump is on battery power. In the event of a power failure, the
pump will automatically continue to operate on battery power.
Two alarms indicate the condition of the pump's battery:
LOW BATT alternating with the selected volume or pressure status. This indicates that approximately 30 minutes of
operating time remains on battery power
LOW BATT (constant). This indicates that the battery is discharged. Connect the pump to an AC power supply to
recharge the battery.
Note: The pump's battery is designed for limited duration use. Wherever possible, the pump should be used connected
to an AC power supply. If the pump is to be taken out of service for an extended period, it is good practice to charge the
battery periodically to ensure full capacity.

Introduction and Start Up
Secondary Infusion (Model 572)
Introduction
This mode of operation supports automatic secondary infusions ("piggybacking") in the same pump channel. When
the secondary VTBI reaches zero, a transition tone will sound and the primary settings will automatically take effect.
Secondary mode can be used where a second, independent VTBI is required, and also when an automatic rate change is
required.
When the pump is programmed and delivering in the secondary mode, the primary infusion is temporarily stopped and
fluid is drawn from the secondary (higher) container. Delivery from the primary container resumes when the fluid level in
the secondary line is level with the fluid in the primary container.
Notes:
1) The primary fluid container must hang lower than the secondary fluid container to allow the secondary infusion to
run.
2) On completion of the secondary infusion the pump will automatically return to primary infusion.
Secondary
Starting the Pump with Secondary Infusion
1. Load the primed set. See 'Loading the IV Infusion Set' earlier in this
chapter for instructions.
2. Prepare the secondary infusion using a secondary solution container
and the IVAC® "52" Series back check valve set; lower the primary
container. See Figure 1-3 below.

WARNING:
Secondary infusion applications using a back check
valve set must have a VTBI setting equal to the
volume in the secondary container; this will require
consideration of such variables as factory overfill,
medication additions, priming volume, etc.
Underestimating the volume will cause remaining
secondary solution to be infused at the primary rate;
overestimating will result in primary solution being
infused at the secondary rate.
When using a flow sensor it must be positioned on the
primary IV infusion set (as shown in Figure 1-4). Correct
placement of a flow sensor is essential for proper
operation.

Calibration Procedures (continued)
Rate Accuracy Calibration (Test 8)
There are two types of rate accuracy associated with the pump, these are System Rate Accuracy and Pump Rate Accuracy.
System Rate Accuracy is the rate accuracy of the pump when used with a standard "52" Series infusion set. Due to slight
variations in between sets, the system accuracy of the pump is ± 5%. Pump Rate Accuracy is the absolute rate accuracy of
an individual pump which can only be determined with the use of a characterised set.
The following procedure describes how to calibrate the Pump Rate Accuracy. For instructions on how to verify Pump Rate
Accuracy, see 'Rate Accuracy Verification' in Chapter 3, 'Routine Maintenance'.
Characterised Sets (part number 191806)
Must be used for rate accuracy calibration
Sets are labeled with a serial number, a nominal volume and an expiry date (180 days from the date
the set was characterised)
Handle sets with care at all times. Sets must not be pressurised. Prior to loading or removing from
the pump, manually open the auto-pinch-off mechanism. Do not stretch the set excessively
Record the number of times each set is used in a log book. A set must not be used for more than 20
rate runs.
Equipment required:
Characterized set (191806)
Stopwatch
Class A burette (50 ml) with 0.1 ml
graduations
Preparation:
1. Set up the equipment as shown.
The vertical distance from the
fluid level of the container to
the pump pressure transducer
should be 34 ±4 inches
The burette zero line should
be within ± 2 inches from the
pump pressure transducer.
Verify that the inside of the
wall is free of droplets
Ensure fittings are secure and
there is no leakage through
the 3-way stopcock
Ensure that the air has been
purged from the characterised
set and all equipment
2. Close the set roller clamp.

Mechanism Leak Test
When servicing the pump, the Mechanism Leak Test must be performed to verify the integrity of
the pumping mechanism.
Misalignment of the pumping mechanism can result in the pressure plate and the mechanism's cam
followers failing to pinch the IV infusion set tubing sufficiently, thereby allowing the pump to leak
fluid at low rates or when stopped.
Procedure:
1. Prepare a special Pressure Test Set as follows:
Take an IV infusion set and cut the tubing a couple of inches
below the drip chamber, discarding the drip chamber.
With a knife, carefully remove the membrane cover from the
white pressure sensing disc, see Figure 3-2. Ensure no membrane
(rough edges) remain—the surface of the pressure sensing disc
should be as flat as possible after the membrane is removed.
Cut out a piece of mylar to match the shape and size shown
below.

do this read the pressure using test 12 (Enter self-test mode, press the RUN/HOLD switch and select test 12).
Warning: A pressure reading greater than 499 mmHg may result in damage to the transducer.
If a high pressure reading is noted, check the following:
The pressure sensing disc is positioned correctly.
The mylar cap is adhered tightly and correctly on the pressure sensing disc.
The height of the mylar cap matches the Myler Cap Shape shown above.
6. Connect the pump to the AC mains then turn the pump ON, entering self-test mode.
7. Press the RUN/HOLD switch and select the burn-in test 29, then within two seconds, simultaneously press and hold
the PRI switch and the CRIS switch.
Verify that the pump is running at 999 (or 999.9 ml/h).
8. Set the rate to 20 ml/h (or 20.0 ml/h) by simultaneously pressing the R AT E switch and the J K switches. Run the
pump for at least one minute. Verify that no bubbles are visible in the water bottle.
If air bubbles are visible in the water bottle, the pump fails the test.
If the pump fails the test, verify set up and repeat the test as required, otherwise, return the pump to the
manufacturer.
9. Turn the pump OFF.
10. Close the roller clamp slowly. Open the door to release any pressure trapped in the pressure test set and carefully
remove the set from the pump.
Note: Take care not to stretch the silicone segment of the set as correct segment length is critical to the mechanism's
pinch-off capabilities.

Rate Accuracy Verification
There are two types of rate accuracy associated with the pump, these are System Rate Accuracy and Pump Rate Accuracy.
System Rate Accuracy is the rate accuracy of the pump when used with a standard "52" Series infusion set. Due to slight
variations in between sets, the system accuracy of the pump is ± 5%. Pump Rate Accuracy is the absolute rate accuracy of
an individual pump which can only be determined with the use of a characterised set.
The following procedure describes how to verify the Pump Rate Accuracy. For instructions on how to calibrate the Pump
Rate Accuracy, see 'Rate Accuracy Calibration' procedure in Chapter 2.
Equipment required:
Characterized set (191806)
Stopwatch
Class A burette (50 ml) with 0.1 ml graduations
Characterised Sets (part number 191806)
Must be used for rate accuracy calibration
Sets are labeled with a serial number, a nominal volume and an expiry date (180 days from the date
the set was characterised)
Handle sets with care at all times. Sets must not be pressurised. Prior to loading or removing from
the pump, manually open the auto-pinch-off mechanism. Do not stretch the set excessively
Record the number of times each set is used in a log book. A set must not be used for more than 20
rate runs.
Preparation:
1. Set up the equipment as shown.
The vertical distance from the
fluid level of the container to
the pump pressure transducer
should be 34 ±4 inches
The burette zero line should
be within ± 2 inches from the
pump pressure transducer.
Verify that the inside of the
wall is free of droplets
Ensure fittings are secure and
there is no leakage through
the 3-way stopcock
Ensure that the air has been
purged from the characterised
set and all equipment
2. Close the set roller clamp.
3. Plug the pump into the AC mains
and turn the pump ON.

Routine Maintenance
Rate Accuracy Verification (continued)
Procedure:
1. Set the pump to Primary rate = 800 ml/h, VTBI = OFF, TOT VOL INF = 000.0 (or, if not using a flow sensor, set the pump
to Primary rate = 800 ml/h, VTBI = 100 ml, TOT VOL INF = 000.0).
2. With the pump displaying START PRIMARY or ON HOLD PRIMARY, press the RUN/HOLD switch to start the pump
and simultaneously start the stopwatch. Allow the pump to run for 180 seconds (3 minutes) ± 0.5 seconds then press
the RUN/HOLD switch to put the pump on hold.
3. Measure the volume in the burette and calculate the percentage of volume error using following formula:
Formula to calculate the percentage of volume error
% volume error =
x 100
n
Where:
b = volume in burette
n = nominal volume as indicated on the
characterised set
4. If the % volume error is ± 2% or less, the pump is within the correct specification. If not, repeat the test.
If the pump fails a second time, perform the 'Rate Accuracy Calibration' procedure. See Chapter 2 for instructions.
Downstream Pressure Occlusion Test
Procedure:
1. Connect an IV infusion set to a fluid container. Prime the set to ensure that air is completely
expelled.
2. Verify and, if necessary, adjust the DEFAULT pressure setting (test 015) and the MAXIMUM
(test 014) occlusion pressure setting to 500 mmHg.
3. Connect a fluid pressure gauge to the luer end of the set.
4. Turn the pump ON and set the pump to VTBI = 100 ml, Primary rate = 499 ml/h.
5. Connect the pump to the pressure gauge by closing the three-way stopcock. Start the pump
and allow it to run until it alarms DOWNSTREAM PRESSURE EXCEEDED.
6. Verify that the pressure gauge reads between 11.0 and 14.0 psi.
7. Open the stopcock to relieve the pressure.
If the pump fails to alarm as stated, perform the 'Dry Set Pressure Calibration' procedure.
See Chapter 2 for instructions.

Routine Maintenance
Physical Inspection and Clean
To ensure the pump remains in good operating condition, it is important to keep it clean and carry out the routine
procedures described below.
Routinely clean the pump, especially if spillage has occurred.
Before cleaning always switch OFF and disconnect from the AC power supply. Never allow fluid to
enter the casing and avoid excess fluid build up on the pump.
Keep pump upright to prevent fluid entry around the pressure transducer.
Do not use aggressive cleaning agents as these may damage the exterior surface of the pump.
Do not steam autoclave, ethylene oxide sterilise or immerse this pump in any fluid.
Unplug the power cord from the AC wall outlet before cleaning. Do not allow fluids to enter the pump case.
Clean the exterior surfaces (the outer case top, bottom, sides; the switch panel, the front panel and inside the door)
with a cloth dampened with warm water, or a mild non-abrasive detergent (such as commercially available dish
cleaning liquid) mixed with water.
Note: Alcohol, ammonia, acetone, benzene, phosphoric acid, xylene and similar solvents can erode (wear away pit)
or otherwise damage the cam followers and other surfaces of the pump. The cam followers must be kept clean using
a solution of warm water and a mild non-abrasive detergent, and inspected for possible erosion according to the
procedure outlined on the following page, see 'Inspecting and Cleaning the Mechanism'.
Check that labels are flat, legible and fully adhered. Replace as necessary.
Inspect the case for loose or damaged components and replace if necessary.
Inspect the circuit breaker for damage.
Inspect the AC power supply plug and cable for damage.
Inspect the door assembly for damage. Check that the door pivots freely and latches securely.
Inspect the mechanism for fluid spill residue or foreign matter. Open the door and inspect the exposed cam followers,
the pressure plate and tubing pincher. Clean any surfaces where solution has accumulated.

crevices.
Manually actuate points (B) by pressing then
releasing each part to verify that it moves freely.
After cleaning is complete, if required and
where heavy spillage has required extensive
cleaning, lubricate the tubing pincher and the
sides of the mechanism (C) using a siliconebased grease.

Physical Inspection and Clean (continued)
Inspecting and Cleaning the Mechanism
Open the door and inspect/clean the exposed cam followers, the pressure plate and tubing pincher.
Clean any surfaces where fluid spill residue is noted, referring to the cleaning instructions above for appropriate
cleaning method.
Check the Cam Followers for cleanliness and erosion:
Shine a flashlight into the cam followers. The followers should be clean and shiny. A dull appearance may indicate
erosion. If the followers appear to be dirty or are dull, clean per the following procedure.
Clean the Cam Followers:
Clean the surface of the cam followers using a cotton-tipped applicator dampened in a solution of warm soapy water
and a mild non-abrasive detergent (such as commercially available dish cleaning liquid). Rinse the cam followers with
a soft cloth or cotton-tipped applicator dampened in water then allow the cam followers to dry.
Check the Cam Followers for erosion after cleaning:
If, after cleaning the cam followers, they are still dull, replace the mechanism assembly per replacement instructions in
Chapter 6 of this manual, or return the pump to the manufacturer.
Verify that the Pressure Plate is not bent, cracked or deformed.
Verify that the Tubing Pincher opens and closes freely (without sticking).
If the pincher is sticking or is hard to actuate, remove the pincher cover and inspect for contamination or inadequate
lubrication. Remove assembly and clean if necessary. See Chapter 6, 'Spare Parts Replacement Procedures' for pincher
removal instructions.
If required, apply a coating of silicone lubricant to cavity in front panel. Refit the pincher, pincher spring and pincher
cover following the instructions in Chapter 6.
Flow Sensor Check (where flow sensor is in use)
Clean the flow sensor by wiping over with a cloth, lightly dampened with warm water and a
standard disinfectant/detergent solution. Ensure the connector does not get wet. Dry flow sensor
before use.
To aid cleaning of flow sensors which have been heavily soiled, contaminated or if the handles
operation is not free, the flow sensor may be immersed and soaked in clean soapy water.
Activating the spring mechanism of the sensor whilst immersed will assist in cleaning the inside of
the mechanism. After cleaning, the sensor should be allowed to dry fully prior to use.
CAUTION: the plug of the sensor should not be immersed as damage will occur.
Check that labels are flat, legible and fully adhered. Replace as necessary.
Check that lenses are clean and clear and show no sign of cracks.
Inspect the body of the flow sensor for damage.
Check that the sliding action of the flow sensor operates smoothly.
Inspect the cord and plug for damage.

Page 45
Circuit Descriptions
Module Overview Functional Description
The IVAC® Volumetric Pump, Models 571 and 572 are designed to be serviced generally to major assembly level.
The main circuitry within the pump is contained on five printed circuit boards (PCBs): Logic PCB, Power Regulator PCB,
Display PCB, Accessory Interface PCB, Analog PCB and a switch panel.
Cardinal Health will make available, on request, circuit diagrams which will assist appropriately qualified technical
personnel to repair those parts of the device which are designated by the manufacturer as repairable.
Logic PCB
Contains the main processor module, memory circuits, I/O
circuits and associated support circuitry which provide
the control functions for almost all the aspects of the
pump. It drives and monitors all other modules using the
program code stored in the EPROM and the RAM ICs.
Main Processor
Consists of an 8-bit microcontroller with an internal
clock generator, vectored interrupts and 64k byte
addressing capability. The processor gets instructions
from the program memory (EPROM U1 and RAM U28,
U29) and then executes them.
Power Control Circuit (& On/Off Switch)
Consists of flip flop (U18) and gate (U17) which are
powered from the VRAM supply so are operational
even when the pump is off. The ON/OFF switch
enables power to the system. It uses a single push
switch on the front panel to toggle the flip flop (U18).
Note if the battery voltage falls below 10.2V, the
microprocessor asserts the OFF signal to toggle U18
into the power-off condition as if the ON/OFF switch
has been pressed.
Wait-State Generator
Memory Address Decoder
Decoding used to select EPROM U13 and RAMs U28
and U29 is provided by various logic circuits.
Read Only Memory (ROM)
The software program is stored in ROM (U13).
Electrically Erasable Programmable Read Only
Memory (EEPROM)
U27, a 128 byte EEPROM is used to retain important
user information such as calibration constants and
operating parameter configurations.
Random Access Memory (RAM) and RAM test
U28 is the read/write memory type and a second RAM,
U29, and various ICs form a hardware RAM test circuit.

Power Regulator PCB
The Power Regulator PCB provides system power supplies,
AC line and battery charging functions, motor control,
watchdog and alarm driver circuits.
Transformer, Rectifier and Filter
Line Regulator
Performs two functions, it is the main power source
when the pump is connected to AC power and it keeps
the battery charged by providing a nominal charge
voltage of 2.35V per cell. The circuit uses an integrated
circuit (U1) , configured as a fixed-frequency pulse
modulation regulator.
AC Line Indicator
AC Power Signal
Power Control Circuitry
+5L Regulator
5.12V Reference and VRAM Regulator
5V Switching Regulator
Clock/Dividing Chain
Crystal Y1, with associated components form a crystal
oscillator which clocks a binary counter. This counter
provides a signal which in turn drives certain circuitry
such as the watchdog alarm and provides timing for the
line regulator and motor control circuitry.
Watchdog
Watchdog pulses enable this circuit to perform an
integrity check on the microprocessor, generating an
alarm if pulses are not received within a defined timing
window.
Alarm Circuitry
Motor Control Circuitry
The microprocessor drives the motor by stepping the
current through each motor winding in the correct order
to cause the motor shaft to turn. Digital signals from
the Logic PCB determine the direction and duration of
the current and the winding is increased/decreased to
ensure sufficient torque to move the mechanism and
to hold its position. The motor control circuit controls
current across a bridge to the windings of the stepper
motor using a pulse width modulation technique.
Battery
The sealed lead acid battery pack consists of six cells each
with a potential of 1.8V to 2.40V, connected in series, a clad
fuse (F2), and a 1.5A fuse (F1). The battery pack is rated at
2.5 Ah at 12 VDC.

Circuit Descriptions
Module Overview Functional Description (continued)
Analog PCB
Consists of two separate circuits, the drop discriminator
which monitors the flow status and the pressure amplifier
which amplifies the output of the pressure transducer.
Drop Discriminator
The drop discriminator circuitry is only active when
a flow sensor is in use. The circuitry consists of a
synchronous demodulator, differential amplifier, an LED
driver, an AGC (automatic gain control) circuit and drop
simulator circuitry.
Pressure Amplifier
The pressure amplifier circuitry comprises four
functional blocks: the chopper/modulator input, the
instrumentation amplifier, the demodulator and the
output amplifier.
Accessory Interface PCB
Comprises the ultrasonic air-in-line detector and the
vacuum detection circuitry. It also acts as an interface
between the Logic PCB and various sensors and
periphery devices including the door sensor, pressure
sensor, Display PCB, motor and the rotation sensors.
Transducer/Vacuum Assembly
The pressure transducer and the vacuum unit make up
this assembly.
Pressure measurement is detected by the pressure
sensor. Pressure sensor readings are provided by the
transducer output voltage taken from a bridge circuit
on the pressure transducer diaphragm.
A cylinder within the pump provides a vacuum to
ports surrounding the front face of the pressure
transducer to ensure firm coupling between the
pressure sensor disc pad of the IV infusion set and the
diaphragm of the transducer.
Display PCB
This board comprises four 7-segment numeric displays,
two 4-digit alphanumeric modules, battery and AC
power LEDs and display circuitry which includes address
decoders, display drivers, and check circuitry. The bezel/
switch panel is an extension of the Display Board via P2.
Mechanism
The motor drives the timing pulley which in turn drives
the CAM, turning the rotation flag. The rotation flag
passes through the two rotation sensors. The function of
these two rotation sensors is to verify that the motor is
turning the correct direction.
Mains Inlet, Circuit Breaker and
Transformer
The AC line voltage is connected to the step-down
transformer through the circuit breaker. The secondary
output of the transformer provides a nominal 24 VAC
which is rectified through a full-wave rectifier, rectified
and converted into an unregulated DC voltage.
Air-In-Line Detector System
Comprises two parts: the air-in-line receiver on the front
panel and the air-in-line transmitter on the door. These
parts sandwich the IV infusion set tubing when the door
is closed and together with the air-in-line drive and
detect circuit they ultrasonically sense air in the fluid
path.

Refitting notes:
1) When refitting the motor, align the two diagonal motor mounting holes with the motor mounting plate before
securing the motor in place with the two screws. Use Loctite 243 on the two screws.
2) When refitting timing pulley (small) onto a replacement motor, install it at the same height as recorded from the old
motor.
3) When refitting the belt, verify the belt tension by pushing on the belt between the pulleys. The belt should easily push
(> 5 pounds of force) by approx. 0.1 to 0.2 inches. Tighten or loosen the belt as required:
Loosen the two motor screws and hold the motor to the mounting plates
Push motor towards the front of the case to lessen belt tension OR pull the motor towards the rear of the case to
increase belt tension.
Retighten the two screws and recheck belt tension.
4) Position timing pulley (large) onto the cam shaft just far enough to keep it off the mechanism plate then tighten the
set screw. When replacing the timing pulley (large), tighten the set screw onto the flat of the cam shaft to ensure
correct flag orientation.
Turn timing pulley (large) so the flag on the timing pulley passes through the optical sensors freely. Ensure the flag
does not rub the sensors. If so, loosen the rotation sensor fixing screw, reposition the flag then retighten the rotation
sensors screw ensuring the rotation sensors do not move.

2) Open the pump door and insert a 0.125" pin gauge in the clamp of the pincher mechanism on the front panel. The
pin must sit vertically and the pin tip must sit below the pressure plate. Locating it any higher will result in inaccurate
adjustment of the pincher cam block.
3) With the pincher cam block free to move but loosely held in place by the securing screw, close the pump door over
the pin gauge. Slide the securing screw to the right until the pincher cam block rests solidly against the pincher then
tighten the securing screw, taking care not to strip the plastic threads.
4) Apply Loctite 420 to the back of the door and around the pincher cam block. Allow to dry for a minimum of 10
minutes before removing the pin gauge.
5) Insert a 0.110" pin gauge in the clamp of the pincher mechanism on the front panel. The pin must sit vertically and the
pin tip must sit below the pressure plate.
6) Close the pump door. Verify that the pin drops out of the pincher mechanism. If not, readjust the pincher cam block.

each frequency range. c
Interference may occur in the vicinity of equipment marked with the
following symbol:
Note 1—At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2—These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures,
objects, and people.
Note 3—Compliance levels raised by EN 60601-2-24.
a The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz are intended to
decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. For
this reason, an additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in these frequency ranges.
b Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and
FM radio broadcast, and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the pump is used exceeds
the applicable RF compliance level above, the pump should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the pump.
c Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
