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.

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.
