Alaris™ GW Volumetric Pump Configuration and Calibration

Teach Learn (Software Versions V5R1F and above) 1. For both the teach and learn pumps in Technician Mode enable IrDA communications (Code 45), and ensure that ASCII / Binary mode and parity bit options (Codes 38 and 39 respectively) are the same. 2. Turn the teaching pump on in normal operation. Note: For multiple teach-learn operations, to avoid call-back alarm every 2 minutes, turn the teaching pump on in Technician Mode. 3. Enter Technician Code 67 on the learning pump. 4. Align the two IrDA ports on the pumps (optimum distance 50 mm). 5. Depress the  key to initiate learning. 6. A progress bar will travel across the learn pump. 7. When successful, the learn pump will display PASS. 8. If the learning pump is unable to learn all configuration parameters then the display will show ConF followed by a list of the configuration parameters that could not be learnt; these will instead contain the factory default settings. This could occur if, for example, the software version of the learning pump is newer than that of the teaching pump.

A

Possible Reasons for failure • IrDA not enabled on both pumps; • ASCII / Binary and parity bit options are not the same; • If the software versions are not compatible; • If the pump models are different; • The line of sight between the IrDA windows was obstructed during data transfer.

Alaris™ GW Volumetric Pump Configuration and Calibration

Calibration procedures 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 CareFusion Service Centre who will be able to assist.

A

Volumetric Calibration should be performed if the Pump is to be used with DEHP free infusion sets.

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: • Occlusion Calibration test set - part number 0000TG00074. Note a fresh segment of the occlusion calibration set should be used for each calibration operation. • Pressure gauge for measuring liquid pressure, with a full scale of 0-2 bar (0-1500mmHg) ±20mmHg. • Volumetric Calibration test set - part number 3236B. Note a fresh segment of the volumetric calibration set should be used for each calibration operation. • Either: -- Class A 50ml glass burette with graduations down to 0.1ml and calibrated down to ± 0.05ml. -- Calibrated scales accurate to at least ± 0.01g.

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. 1. Plug a mains lead into the pump. 2. Prepare a fluid-filled looped infusion set, load it into the pump and close the door. 3. Enter the access code 4. 4. The test will start automatically. The pump infuses at 999 ml/h internally switching to the battery power source to discharge the battery; the air-in-line alarm is disabled. Throughout this test the time indicator will increase in minute intervals. 5. As soon as the pump detects that the battery is discharged, the time shown on the main display will stop increasing and begin to flash. 6. 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 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. 7. Press the  key. When the  key is pressed, the low point calibration value will be stored. Note: 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 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.

8. 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 Power Supply Unit.

Alaris™ GW Volumetric Pump Configuration and Calibration

Displaying the Volumetric and Pressure Calibration Values (CODE 2) Use of this access code simply displays the calibration values stored in the software. 1. Enter the access code 2. 2. Press  to step through all Cal values.

A

If the Volumetric Calibration value is not 18.00, 19.01 or 20.00 then Volumetric Accuracy Calibration is recommended.

3. Switch the pump off if there are no further tests to be done at that time.

Volumetric Accuracy Calibration (CODE 19 and 5)

A

Important Notes: • The balances need to be switched on for 30 minutes prior to use to enable the electronics to warm up and settle. • Always use new test infusion set for each test. If the test ever has to be repeated, a new infusion set must be used. • Do not move the desk during testing, it will upset the balance readings.

Note: For pumps only using infusion sets containing DEHP this calibration procedure is not required.

This test is used to confirm that the pumping accuracy of the system as a whole, including the infusion set, 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 CareFusion Service Centre for further analysis. The head height on Infusion set should be approximately 30cm. Setup A

1. Enter the volumetric calibration code 19 using the f h keys. Press the e key to confirm. 2. Enter the calibration value 19.00 using the f h keys. Press the e key to confirm. 3. Load volumetric calibration set (3236B) into the Pump. Note: a fresh segment of the infusion set should be used for each calibration operation. 4. Enter the volumetric verification code 5. Press the e key to confirm. This will run a verification run on the pump to check that the pump is now within calibration. 5. The pump will initially display . 6. If it is necessary to prime the infusion set, press and hold the  button. The pump will display  and allow the infusion set to be primed, ignoring any air-in-line alarms. 7. Release  once the infusion set is primed and the pump will again display . 8. Zero scales or burette. Press  to begin the verification check. 9. The pump will automatically pump at 125ml/h for a total of 20ml, which will take approximately 9½ minutes. During the run, it will display the volume infused up to that point and intermittently flash r with the run indicator, to show that this is a verification run. 10. At the end of this run, the pump will beep, display 20.-- and wait. 11. Take the final burette/scales reading as the volume infused. The volume infused should be between 19.95ml and 20.41ml. 12. If volume infused is outside limits change the volumetric calibration value by entering code 19. Press the e key to confirm. 13. Enter the calibration value 20.00 if the value is >20.41ml or 18.00 if the value is <19.95ml, using the f h keys. Press the e key to confirm. This will store the calibration value into the pump. 14. Repeat steps 3 to 11 to check that the pump is now within calibration. 1000SM00006 Issue 21

Alaris™ GW Volumetric Pump Configuration and Calibration

Pressure Sensor Calibration (CODE 17) An internal pressure sensor is used to detect downstream occlusions. This sensor requires calibration whenever a new sensor, Control PCB or door is fitted. 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.

Pressure gauge ± 20mmHg

A

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: • Enter the access code 12. Go to test 8 and press . • With no set loaded and door open check displayed value is 11 ±4. • If the reading is outside of tolerance then adjust R2 on the Pressure Sensor PCB until displayed value is within tolerance.

1. Load occlusion calibration test set, 0000TG00074, into the pump to be calibrated and prime the infusion set. Connect to pressure gauge as shown in diagram above. Note: a fresh segment of the occlusion calibration set should be used for each calibration operation. 2. Enter the access code 17. 3. Apply pressure required for each step and when pressure required is displayed on pressure gauge for 10 seconds (allows pressure to settle) press . Calibration values will be returned. Press  to go to next step. PrES step - 150mmHg ± 40mmHg

HI step - 650mmHg ± 40mmHg.

CAP step - 1000mmHg ± 40mmHg.

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

Difference step

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.

Before cleaning always switch off and disconnect from the AC power supply. Do not allow liquid to enter the casing and avoid excess fluid build up on the pump. 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.

Cleaning the Flow Sensor Before the transfer of the flow sensor to a new Infusion set and periodically during use, clean the flow sensor by wiping over with a lintfree 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 handle operation is not free moving, then the flow sensor may be immersed and soaked in clean soapy water (see A). The inside of the spring mechanism can be cleaned by activating it whilst submerged in the water. After cleaning, the sensor should be allowed to dry fully prior to use.

A

The plug of the flow sensor must not be immersed in water as damage will occur.

Storage If the pump is to be stored for an extended period it should be cleaned and the internal battery fully charged. Store in a clean, dry atmosphere at room temperature and, if available, employ the original packaging for protection. Once every 3 months during storage, carry out functional tests as described in this chapter and ensure that the internal battery is fully charged.

Please note during long term storage of the pump the Real Time Clock circuitry is being maintained by BT1 on the control PCB. Under long term storage conditions it is recommended that the pump is powered in Technician Mode for a period of 24 hours so as to keep the BT1 charged, and eliminate the possibility of depleting BT1 and inducing Err9 faults at power up.

Alaris™ GW Volumetric Pump Preventative Maintenance

Updates Upgrading firmware The optional upgrade of the Alaris GW Volumetric Pump software to V5R1F should be considered at the next product service for all Alaris GW Volumetric Pumps fitted with software version V4R2C. Perform upgrades by acquiring the software upgrade kits specified in the spares parts listings. Note: when upgrading Alaris GW Volumetric Pumps from software version V4R1B, first install the V4R2C software upgrade kit to enable the flash upload capabilty.

For installation of software version V4R2C contact your local CareFusion representative. This software version is not available as a spare part.

The major features of the V5R1F software include: • Teach / Learn Capability; • Additional configuration options: --

Silent Mode;

--

SELECT Mode Options;

--

Drop Sensor Connection Mode;

--

Drop Sensor Light Sensitivity Level;

--

Alarm volume level factory default now 4 (was 7);

--

Clear Infusion Parameters to Zero default now OFF (was ON).

• Additional Technician Mode Configuration options: --

New Volumetric Calibration Mode to reduce calibration time (Code 19);

--

New EEPROM Memory Management to improve work with Teach / Learn and to eliminate need to recalibrate pumps following firmware upgrade (Codes 200, 201, 202).

• Automatic setting of VTBI to OFF when used with drop sensor; • Elimination of  error in  Mode resulting in nuisance alarms; • VI now cleared in  Mode and retained upon power down. Recalibration is not required when upgrading from software version V4R2C, although all configuration parameters will be returned to factory defaults.

To ensure the satisfactory operation of IrDA communications when replacing the PSU & COMMS PCB (1000SP01643), the software must be upgraded to V5R2 (1000SP01570).

Alaris™ GW Volumetric Pump Preventative Maintenance 1. Load the software program onto your PC from the Distribution Disk. 2. The CD should automatically load. If not, access the drive and run 'SETUP'. 3. Follow the on screen InstallSheild Instructions. 4. Select the Alaris LVP SMU icon (WinSmug) 5. Place the infrared programming device approximately 50mm directly behind the IrDA window on the rear case or connect the RS232 cable to the 9 pin D type serial port connector situated on the side of the pump. 6. Select the appropriate port (e.g. COM1) on the Alaris LVP SMU program and Press 'Upload'. 7. Briefly depress the  key on the pump to be upgraded; the pump will now display PROG. 8. Switch the pump on for normal operation when the upgrade is complete. If required, the pump will display  whilst automatically completing a test sequence during which the EEPROM memory will be re-partitioned. 9. When the upgrade is complete, enter the Technician Mode and verify the correct software version has been installed; initiate a factory Reset (Code 200). 10. Perform the Self Test checks (Code 3).

Power failure. Power failures may occur when using laptops when communicating with the Alaris GW Volumetric Pump due to power requirements. External power may be used in conjunction with IrDA or RS232 to compensate for lack of power from the laptop. Bright sunlight and strong fluorescent lighting affect the Infrared programming system. If any errors are reported then the RS232 method of upgrading the software should be used. Complete and return the 'Software Upgrade Record' in the 'Appendix' section after performing any software upgrade.
