Wherever you see this symbol in the manual you will find a Toolbox note that highlights an aspect of test or maintenance that is important for you to know about. A typical example is a software upgrade that you should

check has been installed.

General precautions

Please read the general Operating Precautions described in the Directions for Use carefully prior to using this pump.

This pump contains static-sensitive components. Observe strict precautions for the protection of static sensitive components when attempting to repair and service the pump.

An explosion hazard exists if the pump is used in the presence of flammable anaesthetics. Exercise care to locate the pump away from any such hazardous sources.

An electrical shock hazard exists if the casing of the pump is opened or removed. Refer all servicing to qualified service personnel.

This pump is protected against the effects of high energy radio frequency emissions and is designed to fail safe if extremely high levels of interference are encountered. Should false alarm conditions be encountered, either remove

the source of the interference or regulate the infusion by another appropriate means.

If the pump is dropped, subjected to excessive moisture, humidity or high temperature, or otherwise suspected to have been damaged, remove it from service for inspection by a qualified service engineer.

When connected to an external power source, a three-wire (Live, Neutral, Earth) supply must be used. If the integrity of the external protective conductor in the installation or its arrangement is in doubt, the pump should be operated

Configuration & Calibration

This section outlines the procedures for calibration of the Alaris® GW Volumetric Pump.

All of these calibrations should only be carried out by qualified biomedical engineers. If in any doubt about how to perform the tests, in particular the pressure sensor calibration checks, contact your local Cardinal Health Service Centre who will be able to assist.

Calibration procedures

Recommended Calibration Equipment

Specialised test equipment is not required for the majority of the functional tests to be carried out on the pump. In order to calibrate or verify the occlusion alarm point or volumetric accuracy, the following equipment will be necessary:



IV infusion set, suitable for the Alaris® GW Volumetric Pump with standard LUER lock taps for connecting to other test equipment. If the standard sets are not available, it is possible to order a basic "test set" that is available from your local ALARIS® Service Centre

- part number 0000TG00074. Note that all sets should only be used for a single calibration operation. Pressure gauge for measuring liquid pressure, with a full scale of 0-2 bar (0-1500mmHg) ±20mmHg.



either:

Class A 50ml glass burette with graduations down to 0.1ml and calibrated down to ± 0.05ml.



or:

Calibrated scales accurate to at least ± 0.01g.



Volumetric Accuracy Calibration (CODE 18)

The volumetric accuracy calibration routine is used for manufacture of the pump only.

Displaying the Volumetric and Pressure Calibration Values (CODE 2)

Use of this access code simply displays the calibration values stored in the software.

Enter the access code 2.

1. Press  to step through all Cal values.

2. Switch the pump "OFF" if there are no further tests to be done at that time.

Battery Calibration (CODE 4)

The pump must be connected to the AC power source throughout the duration of the test. The test can be aborted at any time by switching the pump off using the  key; no change is made to the battery low point calibration value stored previously in the pump. This calibration should only be performed on a fully charged battery. Ensure the pump is plugged into the mains for at least

24 hours before starting this procedure.

Plug a mains lead into the pump.

Prepare a fluid-filled looped tubing, load it into the pump and close the door.

Enter the access code 4.

The test will start automatically. The pump infuses at 999 ml/h internally switching to the battery power source to discharge the

4. battery; the air-in-line alarm is disabled. Throughout this test the time indicator will increase in minute intervals.

As soon as the pump detects that the battery is discharged, the time shown on the main display will stop increasing and begin to

5. flash.

If the time is greater than two hours and the low point voltage value is within the allowable range of 6.5 to 7.8 volts, then the

6. display shows "PASS" / "xx:xx" / "bx.x", the pass indication, elapsed time and battery low point value in volts. Otherwise the display shows "FAIL" / "xx:xx" / "bx.x".

Press the  key. When the  key is pressed, the low point calibration value will be stored.

If the pump is switched off before the  key is pressed, the calibration value will be lost and the

If the pump is switched off before the  key is pressed, the calibration value will be lost and the test will have to be repeated. When  is pressed, the pump will revert to the technical service

test will have to be repeated. When  is pressed, the pump will revert to the technical service entry mode and flash CodE, followed by 0, this allows you to begin other tests. Switch the pump

entry mode and flash CodE, followed by 0, this allows you to begin other tests. Switch the pump OFF if there are no further tests to be done at that time.

OFF if there are no further tests to be done at that time.

If the pump fails the calibration, try to charge the battery, and repeat the test. If this fails again then replace the battery and / or

8. Power Supply Unit.

Configuration & Calibration

Calibration procedures (continued)

Pressure Sensor Calibration (CODE 17)

An internal pressure sensor is used to detect downstream occlusions. This sensor requires calibration whenever a new sensor, Main PCB is fitted or if door is changed or removed. It is necessary when servicing a pump, to carry out an occlusion pressure test to verify that the sensor is calibrated correctly (see self test routine in Chapter 3 Routine Maintenance). A calibrated pressure gauge will be needed in order to perform this calibration.

PRI

SEC

Pressure gauge ± 20mmHg

When the pressure sensor is replaced the null pressure value must be checked and adjusted, if required, prior to calibration. Check the null pressure value as follows:

1. Enter the access code 12. Go to test 8 and press e.

2. With no set loaded and door open check displayed value is 11 ±4.

3. If the reading is outside of tolerance then adjust R2 on the Pressure Sensor PCB until displayed value is within tolerance.

Load a set into the pump to be calibrated and prime the set. Connect to pressure gauge as shown in diagram above. Enter the access code 17. Apply pressure required for each step and when pressure required is displayed on pressure gauge for 10 seconds (allows pressure to settle) press e. Calibration values will be returned. Press e to go to next step.

PrES step - 150mmHg ± 40mmHg

HI step - 650mmHg ± 40mmHg.

CAP step - 1000mmHg ± 40mmHg.

Difference step

XX or XXX indicates calibration values, that have no tolerance values applicable.

YYY indicates calibration values that should be between 115 and 214.

ZZ indicates a calibration value that is the difference between XXX and XX and should be between 37 and 54.

Do not move the desk during testing, it will upset the balance readings.

This test is used to confirm that the pumping accuracy of the system as a whole, including the tubing, is within the specified limits.

In the most controlled conditions, a needle should be used to pump liquid into the weighing beaker to prevent liquid touching the sides of the beaker and to provide some back-pressure so that leaks/overflows do not affect the readings. As a result of these and other errors, if the system fails just marginally, it is worth performing the test a second time. If it still fails, return the pump to your local ALARIS® Service Centre for further analysis. The head height on IV infusion set should be approximately 30cm.

Flow Stop Mechanism Test

It is necessary to check that the flow stop device can hold sufficient pressure and thus prevent free flow.

Load set into the pump. Use same setup as for pressure calibration (see Chapter 2 Configuration & Calibration).

Open the door and check that the arm stays in the UP position by lifting the arm onto the ledge.

Close the door fully.

Reopen the door and note that the flow stop arm has activated into the down position.

Pull the test tubing out of the pump and place the tube in front of the flow stop mechanism arm in the down position.

Close the door and reopen the door. Check the tubing locator has loaded the tube fully under the clamp and is flat. This checks

6. whether the tubing locator is the correct way around and works.

Ensure the door is open and the flow stop is closed. Apply 650mmHg to the distal end of the IV infusion set for 10 seconds. Then

7. reduce pressure to 500mmHg to the distal end and verify pressure gauge reading is 500mmHg. Ensure the pressure does not drop by more than 15mmHg in 30 seconds.

Troubleshooting

Alarm types

Non Recoverable Alarms

In this state the pump will stop the infusion and give an audible and visible warning to alert the user that a non recoverable alarm (registered on the pump as a Fatal alarm) has occurred. With the exception of a micro-controller (MCU) error or internal communications fault with the external EEPROM, each alarm condition is identified by a unique code, which is stored in the alarm history log each time an alarm occurs, to enable the qualified service engineer to trace the error condition. From a non recoverable alarm the user is able only to enter the POWER DOWN mode. The non recoverable conditions are defined in the alarm code table.

Recoverable Alarms

In this state the pump stops the infusion and gives an audible and visible warning to alert the user to the alarm condition, and to provide an indication of the nature of the alarm. Each alarm is identified by a unique code, which is stored in the alarm history log each time an alarm occurs to enable the technician to trace the alarm condition.

The recoverable alarms are defined in the alarm code table. After a recoverable alarm has occurred, the pump responds only to the following three actions: the user may temporarily silence the alarm for one minute by depressing the  key; this action will suspend only the audible indicator, with the visual message remaining. After one minute the audible indicator will return.

The pump may be switched off directly from the ALARM mode by depressing and holding the  key, to initiate the power down sequence. If the power down sequence is not completed, then the pump immediately returns to the ALARM mode and initiates the audible alarm.

To return the pump to the “HoLd” mode, the user presses the  key; this action clears the alarm message on the main display and silences the audible indicator.

Circuit Descriptions

Module overview functional description

The pump is designed to be serviced generally to major assembly level. The PCBs are designed as non-serviceable items and as such, can only be replaced as complete parts.

Cardinal Health will make available, on request, circuit diagrams, which will assist appropriately qualified technical personnel to repair those parts of the pump which are designated by the manufacturer as repairable.

The main circuitry within the Alaris® GW Volumetric Pump is contained on three printed circuits boards - Control PCB, Power Supply and Communications PCB, and a small Pressure Sensor and Encoder PCB and additional plug in sensors.

Control Board

Microcontroller Block

All control and display functions are controlled by this part. Safety functions are spread around the pump with various parts. The controller is supported by a watchdog and power reset circuit. An EEPROM is used to store logged data for the pump. There is a battery backed real-time clock.

Power Control Block

Raw DC power is connected from the Power Supply unit to JP1 connector. In the event of the raw DC exceeding 36 volts, components form a crowbar. Components form a 12 volt Switch Mode Power Supply (SMPS). Components form a 12-volt monitor circuit for the Microcontroller. The battery is connected to pin 3 of JP1 and is constantly charged when connected to the mains. Components form a 5-volt reference voltage to the main processor. A switch mode regulator supplies 5-volts (VCC) to the pump. There are two 5-volt crowbar protection circuits.

Motor Driver

A Microcontroller I/O is used to control the motor speed. The modulated signal is smoothed to a DC voltage appropriate to control motor speed. Relay 1 is used to reverse the voltage applied to the motor. This reversal is used for some modes of operation. Safety devices stop the motor if necessary.

User Interface

Microcontroller drives the seven segment displays and the LEDs. The keyboard is scanned for key depressions .The display currents are monitored. Time division multiplexing enables complete control of a user interface display and input with the Microcontroller.

Air-in-line sensor

A phase shift oscillator drives the Air-in-Line sensor; the output of the phase shift oscillator signal is fed into a voltage controlled oscillator. The signal is transmitted through the fluid filled tubing and received by the ultrasonic sensor. The received signal is then passed through a window detector and then to a level detector and input into the Microcontroller.

Air-in-Line

Two ultrasonic transducers continuously check for the presence of air in the IV infusion set throughout the infusion. This air-in-line feature operates in two modes:

Single Bubble Detection - The pump will alarm and display Air OCCL whenever a single air bubble greater than the air-in-line volume alarm limit is detected. The alarm limit can be configured to 50, 100, 250 or 500µl. See also “Configurable Options” section of Chapter 2.

Air-in-Line Accumulation - This accumulation feature monitors the volume of air that passes through the IV infusion set by accumulating the volume of individual bubbles over a 15 minute window. The accumulation will alarm if more than 500µL of air is registered. This feature is particularly useful with infusions for patients that are highly sensitive to air (i.e., neonates, paediatrics) or when infusing products that create significant volumes of small air bubbles.

Flow sensor

The flow sensor is input into the Main Processor.

Door sensor

A Hall effect sensor detects if the door is open or closed and a Microcontroller reads the state of the sensor.

Buzzer

The Microcontroller is used to switch on the alarm (buzzer).

Audio Alarm

The input to the Audio alarm section is driven by a signal from the Microcontroller, fed into a phase shift oscillator and through an RC network to remove any DC present on the signal. The signal is amplified and drives the speaker.

Alaris® GW Volumetric Pump 29/77 1000SM00006 Issue 4

Circuit Descriptions

Power Supply Unit and Communications Board

Power module

The selection of 115V or 230V is made via S1. The secondary is rectified to an unregulated DC Voltage. F2 is a Polyswitch resetable fuse. The raw DC is output to the Control PCB. The battery is connected via JP3, the maximum current being limited by F1.

RS232 & Nursecall

The external RS232 connection is made via JP5 where power for the 4kV isolated interface is taken from pins 4 and 7. This voltage is converted to a 5-volt supply and in turn converts the RS232 communications levels to TTL which are then sent to the Microcontroller. The Nursecall interface is controlled from the Microcontroller to energise the relay which causes the contact to change over.

IrDA Module

IrDA or RS232 is selectable. The IrDA communication signal is output from IC7.

Pressure Sensor and Encoder Board

Motor encoder

Diodes D1 and D2 are the emitters in the motor encoder and OPT1 and OPT2 being the receivers. The signals are sent to the Control PCB where they are used in conjunction with the Pressure Sensor and Encoder PCB to provide a quadrature detection scheme from the rotary encoder on the drive motor. These signals are then processed via the Microcontroller.

Pressure sensor

The strain gauge is connected to the Pressure Sensor PCB, the sensor o/p signal is then amplified and then output to the Control PCB and used to provide a second stage of amplification for the pressure sensor signal. This signal is processed via the Microcontroller.

In order to replace a front case, it will be necessary to fully strip down the old case and insert all of the components into the new

1. front case. The task requires a good knowledge of the pump, so be certain that you are fully conversant with all of the procedures in this section before undertaking this replacement. In order to simplify the task, new front cases are supplied with the flow stop mechanism, air sensors, and the finger and pressure sensor covers already fitted, so it is not necessary to remove these from the old case.

For each sub-assembly to be stripped down, follow the instructions in the relevant section of this manual. The recommended

2. order for stripping down a front case is described below :

Separate the front and rear case halves;



Remove the Control PCB;



Remove the door assembly;



Remove the Pumping block assembly (keeping the motor on the chassis);



Remove the pressure sensor.



When re-assembling these sub-assemblies into the new case, it is advisable to simply reverse the order of dis-assembly.

It will also be necessary to apply a new front panel label, door label and flow direction label at the end of assembly. These labels are language specific. Refer to the “Spare Parts Listing” in this service manual to ensure that you order the correct label set. The part number should also be shown on the labels that were removed from the old case.

Write the serial number of the pump on the label provided and stick it onto the inside of the new case.

Door assembly

Remove the air sensor assembly from the back of the door and retain the small screws for re-assembly later.

Remove circlips and push out the two shafts that form the hinge of the door so that they clear the first part of the hinge.

2. Do not free the main pressure plate that is sprung on the door.

The old door assembly will now come free from the front of the pump.

Reassemble in reverse order.

When fitting the door, take care to keep the air sensor on the correct side of the door and do not crush its wires.

Reassemble in reverse order. Tighten the countersunk screws first, then the pan head screws. Ensure the pumping fingers are

5. the correct way around with the narrow curved end in contact with the tubing. Fit a new flow direction label to the front of the pump.

IMPORTANT: Recommended when serviced, grease should be applied a minimum of once every 12 months.

The Alaris® GW Volumetric Pump uses Molykote grease (F) to lubricate the moving mechanical parts of the pumping mechanism to reduce the current draw of the pump. Only Molykote PG54 grease has been approved as compatible with the pump components. Each of the cams should have a thin layer applied to the circumference so that the fingers run smoothly over the cam face. The grease can be applied by a lint-free cloth or finger for example, to achieve an even layer over each cam.

Electromagnetic Environment – Guidance

Portable and mobile RF communications equipment should be used no closer to any part of the pump, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter.

Recommended Separation Distance

3.5 d = [-----] √P

12 d = [-----] √P 80 MHz to 800 MHz

12 d = [-----] √P 80 MHz to 2.5 GHz E

23 d = [-----] √P 800 MHz to 2.5 GHz E

where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m).

Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, b should be less than the compliance level in each frequency range.

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.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be determined using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the

transmitter manufacturer.

Note 1—At 80 MHz and 800 MHz, the separation distance for the higher frequency range apply. Note 2—The ISM (Industrial, Scientific, and Medical) bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz. Note 3—An additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. Note 4—These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.

Fitting & Replacement Guidelines

General assembly information

A wide range of self-tapping fasteners are available.



PT screws are for plastic, self-tapping applications.



Almost all fasteners on the Asena® GW Volumetric Pump are self tapping and have the potential to be over tightened (over torqued).



The force required to create a thread for the ﬁrst time is more than when reassembling a previously made joint.



Always use the correct torque level when ﬁrst making an assembly stage.



Take care with the torque applied when re-assembling parts. Less torque is required, so a hand tool may be more appropriate.



In many situations a stripped thread will require replacement of the failed component.



The head patterns of the fasteners are of the following types:



- Pozi Number 1 (smaller X head)

- Pozi Number 2 (larger X head)

- Torx Number T8 (Small star profile, used typically on countersunk parts with smaller heads).

- Torx Number T10 (Medium star profile)

- M6 nut

Always select the correct tool and bit pattern for the fastener.



Torque guide

The following list outlines the torque levels established during pump manufacture.

Torque levels selected apply throughout product life for the Asena® GW Volumetric Pump.

Use this information as a guide to the 'do not exceed' torque levels when servicing the pump. When servicing it is recommended that torque is applied gradually until the component is secure. In any process do not exceed the stated levels.

If a torque driver is available for servicing, this will help control the applied torque; otherwise, be aware that excess force may cause the component to fail.
