Warnings and cautions
AC input power connecting socket/cable
The AC input power socket that connects to the rear of the pump has three connections (live, neutral and earth)
provided by a 3-way power cable. As the casing is doubly insulated, the AC input connector situated on the pump
only utilises two connections (live and neutral), there is no third earth pin. This method of AC input enables similar AC
input sockets (if required) to that supplied by Smiths Medical to be used.
Introduction
This Technical Service Manual together with the Instruction Manual, contains all the information that is needed in order
to maintain, repair and operate the Graseby 3200 pump.The contents of this Manual are intended to be read and used
by suitably qualified personnel.
Warnings and cautions
Warnings tell you about dangerous conditions that could lead to death or serious injury to the user or patient that can
occur if you do not obey all of the instructions in this manual.
WARNINGS
1. WARNING:To avoid over- or under- infusion, always verify that the brand and size of the loaded syringe are the
same as the brand and size displayed on the screen before starting an infusion. Failure to do so may result in an
inaccurate delivery of medication, resulting in patient injury or death.
2. WARNING:To avoid incorrect or inappropriate configuration of the pump, the Configuration menu must only be
selected by qualified persons or authorised personnel. Incorrect pump configuration could lead to inappropriate
infusion resulting in patient injury or death.
3. WARNING:This equipment is not suitable for use in the presence of flammable anaesthetics, oxygen-enriched
or explosive atmospheres. The use of the device in such atmospheres may lead to explosion or fire.
4. WARNING:To avoid possible malfunction of the pump, do not expose the pump to X- rays, gamma rays or
ionizing radiation, or to the RF interference or strong electric/magnetic fields emitted (for example) by diathermy
equipment or mobile telephones. If the pump is used in the presence of, or in combination with Magnetic
Resonance Imaging (MRI) machines it must be protected from the magnetic field emitted by such equipment.
Malfunction of the pump can cause incorrect infusion or loss of infusion resulting in patient injury or death.
5. WARNING: Operation of the pump outside the temperature limits defined in the specification may result in
erroneous operation. Ensure that the temperature is within the specified limits. Failure to do so may result in
patient injury or user injury.
6. WARNING: In order to ensure that the intended infusion is performed, data must be entered correctly. Likewise
before confirming any displayed data the user should ensure that it is correct. Failure to do so may result in
compromised function of the product, patient injury or user injury.
7. WARNING: Failure to respond promptly to an alarm may result in patient injury or death.
8. WARNING: Failure to follow the
Service Manual’s maintenance schedule recommendations may result in
compromised function of the product and lead to patient injury or death.
9. WARNING: It is essential that clinical staff remain within visual and audible range of the pump so that critical
alarms can be seen or heard and responded to.
10. WARNING: The user should ensure that the performance offered by the pump is fit for the intended purpose.
Failure to do so may result in compromised function of the product, patient injury or user injury.
11. WARNING: When the pump is carrying out an infusion, to ensure that electrical safety is maintained only items
of equipment that conform to EN60950 are to be connected to the RS232 connector situated at the base of the
pump, otherwise patient safety may be compromised.
12. WARNING: Correct management of battery charging is essential to ensure that the pump can operate on
batteries for the time specified. Failure to do so may lead to impaired functioning of the pump, resulting in
patient injury or death.
13. WARNING: Do
not use a faulty pump. If the pump develops a fault then an alarm will sound; the display will
indicate a FAULT condition and the pump will fail to infuse. Incorrect performance of the pump can cause
complications resulting in patient injury or death.
If the pump develops a fault then it must be referred to a suitably qualified engineer or returned to Graseby
Medical in order to have the fault rectified.
14. WARNING: Failure to use the mains lead clamp means that the pump may be accidentally or erroneously
disconnected from the mains. Although there is battery backup in case this happens, the battery may not be
sufficiently charged. Consequently there is a risk of the pump not functioning, which could lead to patient injury
or death.
15. WARNING: If an occlusion alarm occurs, immediately clamp the line to eliminate the possibility of a bolus being
delivered to the patient. Then inspect the fluid pathway for kinks, clogged catheter, etc. in order to remove the
occlusion prior to restarting the infusion. An unintentional bolus of medication can result in patient injury or
death.

Smiths Medical International Ltd.
Issue 5 (August 2004)
3200 Service Manual Page xi
16. WARNING: Use only the syringes and administration sets listed in the Specification (Chapter 1).
Failure to do so may result in an inaccurate delivery. Smiths Medical does not guarantee performance of the
pump if syringes other than those listed are used. Incorrect function or performance of the pump can cause
complications resulting in patient injury or death.
17. WARNING:The volume of fluid contained in the connecting tubing is a residual amount and will not be infused.
Hence this extra volume of fluid must be allowed for when initially filling the syringe and purging the system.
Under-delivery of medication can cause complications resulting in patient injury or death.
18. WARNING:To avoid patient embolism, ensure that the patient tubing is purged of all air bubbles before
administering any medication.The pump provides a purge facility to assist with this process. The presence of
air within the medication can result in complications leading to patient injury or death.
19. WARNING:To avoid syphoning of the syringe contents (free flow), ensure that the syringe is correctly loaded
into the pump, that the syringe plunger is properly engaged by the pump’s actuator and that the pump is placed
not more than 80cm above the infusion site. Syphoning can result in over-infusion leading to patient injury or
death.
20. WARNING:To avoid over-infusion, do not purge the infusion line when the administration set is connected to the
patient. Over-infusion of medication can result in patient injury or death.
21. WARNING: To avoid the pump becoming detached from an IV pole always make sure that the pump is securely
fixed to the pole. Always check the security and stability of the assembly with the pump mounted.
22. WARNING: Following a significant liquid spill onto the pump, it should be wiped dry and inspected by service
personnel before being returned to service. Failure to do so may result in compromised functioning of the pump,
leading to patient or user injury or death.
23. WARNING: When using a syringe smaller than 50/60 ml the occlusion pressure will increase as the diameter of
the syringe decreases, i.e. the smaller the syringe the higher the pressure.
24. WARNING: For high risk or critical infusions, the use of the dedicated 3200 Extension set incorporating the
pressure sensing disc is recommended in order that occlusion pressure can be appropriately set and
monitored during an infusion.
25. WARNING: The patient history is lost when the clock is reset.
26. WARNING: Only adequately qualified personnel should maintain and repair the pump.
27. WARNING: The pump must be disconnected from the AC power supply before the case is opened.
28.WARNING:The Configuration and Diagnostic mode must only be used by personnel who are adequately qualified and
have previous training in the use of the pump.
29.WARNING:The safety and reliability of the pump may be compromised by the use of parts other than those specified
in this Manual.
30.WARNING:When a new Syringe Size Sensor Flag has been fitted to the pump (see Appendix), then the pump must be
tested using the new syringe size sensor gauges available from Smiths Medical (part number 0131-0202). Page 3 of
the Appendix gives details of the Final Testing procedures.
31. WARNING: The pump must be set to display the brand and the size of syringe that is going to be used. Using a
different brand or size of syringe to that being displayed could lead to the incorrect amount of drug being administered,
that could result in injury or death.
32. WARNING: The internal pump batteries must be disposed of in accordance with the manufacturers instructions.
Lead acid batteries must NOT be placed in the normal waste stream.

3200 Service Manual 1 — 1
CHAPTER 1
INTRODUCTION, FEATURES and SPECIFICATION
The 3200 is a microcomputer controlled syringe pump that has primarily been developed for
the neonatal infusion of sterile liquids.
The pump has an In-line (wet-side) pressure sensing system for accurate occlusion detec-
tion.
The pump is capable of operating in any one of three different infusion modes, as follows:
• continuous,
• preset, or
• intermittent.
And is able to carry out an infusion using a 5, 10, 20, 30, 50/60 ml size syringe.
The pump incorporates a dot matrix vacuum fluorescent display that provides a constant
indication of the pump’s operation. A choice of any one of the following languages is avail-
able (with the appropriate software) via the diagnostic options mode:
English, Dutch, French, German, Italian, Norwegian and Spanish.
The pump can be Configured by the user to work with one of a range of brands of syringe.
It automatically senses the size of the syringe fitted to the pump. The rate of the pump can
be set to operate with either mass units or ml/hour.
The pump is able to dispense liquids at rates of between 0.05 and 200 ml/hour.
The pump keeps the running total of the volume infused, and a history of events as they
occur. About 1,500 events can be logged, complete with the date and time of each.
This compact and robust pump can be used on either a table top or mounted via its pole
clamp to an IV (Intravenous) pole. The pump’s history can either be viewed on the screen or
output to a printer.
An RS232 interface link connects the pump to either a printer or a computer. This allows the
pump’s history to be printed or externally monitored.
Safety features are built into the pump and its software. This includes a set of self test
routines which are run when the pump is switched on.
Users are warned of such incidents as occlusion or power failure by both visible and audible
alarms.
The pump can be powered from either an AC supply or internal rechargeable batteries.
The batteries can power the pump for at least two and a half hours from a fully charged
condition.
A DC version of the 3200 also exists, that requires an input supply of 10 V to 28 V DC (see
Chapter 9).
This Manual refers to pumps that have software Version 2.20 installed. Software versions
other than 2.30 may show slight deviations from certain features described in this Manual.
An optional security cover kit is available (part number 0131-0277). The kit includes all the
items required to modify the pump, including comprehensive fitting instructions. When fitted,
the kit protects the syringe from tampering only; it provides no other security. It does not
lockout the keypad or give audible or visual alarms when opened.
