INTRODUCTION

HS 66

HS 66 is the designation of a series of GETINGE high-pressure autoclaves with vertically sliding automatic doors, all with the door opening 660 x 660 mm

There are both stand-alone and built-in versions.

The autoclaves are intended for sterilization of materials in the health service as well as in industry. They are adapted to their particular functions by the choice of control equipment. This is built up around a microprocessor and therefore provides a very large number of process types, all characterized by exceptional accuracy in controlling the process parameters. The operator can call up on a display information on the current process, current pro cess phase and the actual values of the parameters while the process is in progress.

The dominant sterilizing agent is steam at a temperature of 121 -134 °C. Material that is damaged by this temperature may be sterilized in some autoclave models in formalin vapour at 55 - 80°C.

Most types of items can be treated in the HS 66-autoclaves, using adapted programs: Instruments, machine parts, glass, plastic, leather, textiles, hot or cold liquids in open or vented containers and small rigid pressure-tight containers filled with liquids.

INTRODUCTION -

European standard EN 285 (Australia/New Zeeland, Standard AS 1410) specifies the use of fixed programs only. However, the control equipment of HS 66-autoclaves allows the programs to be made variable during the time testing is in progress.

As not only the processes but door operation too are controlled automatically, the step to full automation of the handling of sterile items is not a long one. The control unit is therefore prepared for controlling an autoclave having a GETINGE ASF automatic loading and unloading unit.

As with other GETINGE double-jacketed autoclaves, the external surface of the cham ber is more than half c overed by all-welded U-sections.. These stiffen the fla t walls of t he pressure vessel, and at the same time accommodate the stea m which keeps the cham ber walls warm in order to minimize condensation in the chamb er. The design principle makes all welds accessible for visual i nspec tion aft er t he th ermal insulation has been removed.

A vacuum pump of the water-ring type removes air, steam and condensation from the chamber and door-gasket groove. The sealing water of the pump is taken from an open tank which in some cases also supplies the feedwater pump, on autoclaves with a steam generator, with water.

The condenser between the chamber and vacuum pump converts waste steam to water. This reduction of the pump handling volume contributes greatly to improving pump efficiency and protecting the pump and waste pipes against high temperatures.

A well-damped discharge system after the vacuum pump and welldimensioned thermal insulation around the chamber mean that the autoclave affects the surroundings to an insignificant extent and is therefore easy to position.

HS 66-autoclaves have to be supplied with electricity, cold water, compressed air and steam. When steam is supplied from a central steam-producing plant, its distribution system is required to be correctly pressurereduced, protected by a safety valve and produce a quality of steam which is suitable in the context of sterilization. (For some versions the pressure reducer is already fitted)

If the steam is not suitable in the context of sterilization, a steam generator can be installed inside the trim plates on all models. The task of the

INTRODUCTION

steam generator is to generate pure steam using the centrally produced steam.

If there is no steam network or there are reasons for not using the steam network, an electric steam generator may be installed inside the trim plates on all models.

Overview of safety de vi ce s

Cladding and front panels must prevent access to the parts of the installation that are normally accessible only to trained personnel.

General access to an installation supplied without cladding, which should normally only be maintained by trained personnel must be prevented. A convenient way of preventing access is to install the equipment in a lockable area.

Additional information about the above safety components are given in the “Safety checks”, “Utility data” a nd “Periodic maintenance” sec tions of the TECHNICAL MANUAL.

Safety components

Every unit is equipped with a number of components with the specific purpose of ensuring the safety of personnel. These items are marked with a warning triangle below in the following documents:

•

These components have undergone special tests before being accepted as safety components. For this reason, they must not be replaced with components of any make or design that has not been appr oved by GETINGE.

It is of the highest importance that the operational reliability of these components is continuously upheld during their entire service life.

electrical diagrams pipework diagrams spare parts lists

The signs are used not only to indicate important components, but also to draw attention to other safety factors that call for special attention, such as dimensions, tolerances, materials, etc.

INTRODUCTION -

Doors

Emergency stop

The doors are closed and locked while the process is running and remain locked in the event of media loss. The doors cannot be opened until the pressure in the chamber has been equalized with the ambient pressure, not even if fault management gives an opening command. The sliding doors are operated by a compressed air cylinder which has a severe ly throttled inlet. A drain valve with a considerably greater flow capaci ty than the inlet is located in the bottom of the cylinder, which is pointing upwards. Objects that obstruct the upward motion of the door pr ess down a metal plate which op ens the drain valve, causing the do or motion to stop. This prevents operator injuries and material damage. A support latch holds the door so that it does not open if the pneumatic operating cylinder loses pressure. When the pressure of the compressed air is so low that the door cylinder cannot support the weight of the door, the air is not capable of pulling away the support latch.

In the front panel, at the side of the door, there is a pushbutton with these functions:

A On door operation.

B When the door is closed

Door interlock key

The front panel contains a key switch, intended for use whe n cleaning the sterilizer or when it is necessary to reach into the chamber for any reason. With the key removed, the door cannot be closed. See also under "Cleaning the chamber" in the Operation chapter.

Trim plates

Panels are possible to dismount by means of tools or keys. The panels form a barrier for ope rators, but not for specially tra ined technicians. Stainless steel surfaces within reach of the operating personnel are insulated and cooled to a harmless temperature.

to stop the door motion immediately during door operation. Pressing the button triggers an alarm. This alarm stops the door immediately:

The current process is aborted and all valves for media to the chamber are closed. This also triggers an alarm.

Valves

INTRODUCTION

If the equipment has electrically and/or pneumatically actuated valves they are normally made to close by means of spring force. This prevents

Pressure vessels

Safety valves

undesired flow through the valves in case of power failure. A f ail safe function is achieved.

The sterilizer chamber jacket and steam generator are pressure vessels, designed and built in accordance with standards laid down by official bodies charged with monitoring this area of safety.

The internal steam supply to the sterilizer is protected against excessive supply pressure by a safety on the steam generator, the sterilizer or both.

The connected supply lines from external steam, water or compressed air networks must be protected against exce ssive pressure by safety valves. The sterilizer supplier is not responsible for these valves. Permitted supply media pressures are stated in “Utility data”.

Safety valves limit the system pressure, providing the last line of protection to prevent the design pressure of the vessel from being exceeded. Safety valves are required to be inspected at prescribed intervals.

Monitoring the pressure behind the door seal

All valves admitting any medium to the chamber are kept closed until the pressure behind the door seal is high enough to guarantee the tightness of the chamber.

Built-in electrical stea m generator

The sterilizer also has a fully-automatic built-in steam generator, with tubular electric elements as the heat source.

Operation

The heating power is divided among a number of groups of elements. The elements are controlled by a pressure switch with double changeover contacts, one for each heater element circuit. One group of contacts limits the operating pressure of the steam generator. The other controls reconnection of the power when the minimum pressure is reached.

Pressures higher than those stated on the electrical diagra m should not be set, since the steam will be superheated when admitted to the sterilizer chamber. On the other hand, if the operating pressure is allowed to fall too far, the steam tends to become wet, which is undesirable for sterilisation purposes.

INTRODUCTION -

A feedwater pump supplies the steam generator with water from a n integral water tank with air trap. The water level of the steam generator is sensed by a device which controls the operation of the pump so that the level is kept almost constant. Boil-dry protection cuts off the supply of electric power to the elements when the water level is low.

See also “Steam generator settings and controls” under Advice and instructions in the TECHNICAL MANUAL.

Control switch

The steam generator and sterilizer are controlled by the same switch. On sterilizers with med double steam systems there is an extra shutoff button marked Steam generator.

Pressure regulation in power stages

The system prevents wear of the element contacts by switching the power in and out in two stages at d ifferent pressure levels and with a time offset between switch-on and switch-off for the first stage.

Spark-reduction connection

As well as shortening the life of electrical contacts, sparking at the contacts may also cause interference with nearby electronic equipment. The anti-spark protection is based on fast-act ing a uxiliary rela ys t aking over the load from the slow-breaking contacts of the pressure switch for operating pressure, so largely eliminated sparking.

Safety valve, steam generator

The mandatory periodic check of the operation of the steam generator safety valve can be done simply by means of the keyswitch described below. See also the Maintenance chapter in the TECHNICAL MANUAL.

Keyswitch “Test pressure limiter”

When the key is in the safety valve check position, steam is produced continuously and regardless of the setting of the operatin g pressure switch.

Water level regulation

Version with conductive measurement

The Getinge conductive level system is designed for water with a conductivity above 2 μS/cm.

12 -

INTRODUCTION

The task of the level device is to sense and control the water level of the steam generator. The main components are a sensitive relay and two electrodes, the ends of which touch the water surface at the upper and lower fill levels. Contact of the upper electrode with the water stops the feedwater pump, whilst absence of contac t at th e low er elec trode st arts the pump. A third, lowest, electrode cuts off the electric powe r supply to the heating elements when the electrode loses contact with water; see boil-dry protection below.

The type and sensitivity of the level relays can be adapted to varying water conductivity. If the f eedwater is de-ionised, a high-sensitivity level relay is required and the sensitiv ity setting must be increased as the conductivity of the water decreases.

The sensitivity of the level relay is automatically adjusted at power up to match varying conductivity.

The distance between the electrodes is another factor that affects the overall sensitivity of the level control system.

Version with float

The GETINGE f loat-based level cont rol system is intended for water with a conductivity of 0 to 2 μS/cm, but it can also be used for higher conductivity.

The task of the level device is to sense and control the water level in th e steam generator. The main components are a float with two level contacts and two relays. The level contacts change over at the upper and lower fill levels. The upper contact stops and starts the feedwater pump, whilst the lower contact cuts off the electric power supply to the heating elements; see boil-dry protection below. The purpose of the relays is to protect the float contacts from harmful currents.

Water-level monitoring

A lamp in the “reset level” button on the steam generator control panel is lit when the water level is correct. On some models, the water level can also be read off on a sight glass. The sight glass has two valves which can be closed to prevent loss of water and steam in the event of breakage of the sight glass.

Boil-dry protection

If the water filling fails, the boil-dry protection cuts of f the electric power supply after a certain time, when the water level has fallen below a minimum limit.

Overheat protection

This protection prevents the steam generator from overheating if the boil-dry protection should fail to operate.

INTRODUCTION -

Overfilling protection

The timer relay prevents the steam generator over-filling with feedwater if the level control system stops working.

“Reset level” button

If a fault occurs on any of the safety components of the steam generator, it must be reset manually in accordance with applicable boiler regulations.

The button is also used when filling an empty steam generator with water. See the Function check chapter in the INSTALLATION MANUAL.

“Test level limiter” button

This button is provides a quick test of the operation of the boil-dry protection. The test interrupts the level circuit without the need to reduce the water level.

RCD

Safety switch

Some types of steam generator must be connected to the electric power supply via a residual current device (RCD). See the Installation instruc- tions chapter in the INSTALLATION MANUAL.

It must be possible to isolate all electric power supplies to the steam generator with a safety switch. The safety switch must be locka ble in the OFF position. See also chapter Installation in the INSTALLATION MANUAL.

INTRODUCTION

THE PROCESS

The steam sterilizing process

The universal steam autoclaving process can be divided into three main phases:

APre-treatment B Sterilizing C Post-treatment

Pre-treatment

Sterilizing

It has been found that moisture is an essential element in achieving sterility with steam. It is therefore important that the steam comes into close contact with the micro-organisms to be killed.

A pre-treatment phase consisting of a number of pressure variations following a certain pattern effectively removes air from various types of goods and produces the moisture required in the subsequent sterilizing phase. Depending on the equipment of the sterilizer, steam may pass through before the evacuations.

Air removal when autoclaving liquids in open containers is by applying a vacuum or by flowing steam, to ensure that the liquid does not boil during the decompression periods in a pulsating procedure.

For sterilizers equipped with a computerized cont rol unit, the sterilizing time starts at the instant in the pre-treatment phase of the process when the chamber temperature sensor signals a temperature equal to or higher than the sterilizing temperature specified for the current program. An alarm sounds if the temperature sensor registers a value outside the temperature band, or if the temperature differs by more than the permitted amount from the chosen sterilizing temperature.

THE PROCESS -

Post-treatment

When sterilizing liquids, the te mperature is measured with a temperature sensor in the load. The condition for countdown of sterilizing time is that both temperature sensors in the chamber and the sensor in the load indicate the programmed sterilizing temperature.

The purpose of the post-treatment is to normalize the temperature and moisture content of the goo ds. All goods except liquids are therefore exposed for a certain time to a vacuum below 70 mbar (a). After suc h post-treatment. textiles may appear to increase in weight by about 1%. This represents the normal addition of water that occurs during steam autoclaving process.

Post-treatment of liquids that have been sterilized in open or half-closed containers consists of a self-cooling period. During this period the pressure and temperature are lowered very slowly until the temperature is well below the boiling point of the liquid. This process is speeded up by applying a slight vacuum to the chamber when its pressure appr oaches atmospheric.

NOTE: Liquids must only be processed in sterilizers which have a program for this type of load.

Pressure equalization from vacuum takes place by admitting atmospheric air into t he cham ber via a f ilter tha t preve nts bact eria from entering the chamber. The efficiency of the filter is 99.998% for particles of the order of 0.3 micron (0.0003 mm) in size.

The sterilizer door is kept closed by the door gasket until the pressure in the chamber is equal to atmospheric pressure.

Process adaptation

A large number of factors such as type of goods, goods carrier, packaging material, etc. affect the result of the process. The control equipment offers a number of features that can be used to optimize the processes to suit the requirements of different customers. For further information, see "User-programmable functions" in the TECHNICAL MANUAL.

THE PROCESS

Maintenance program

Leak test

Fully automatic process for steam autoclaves

With autoclaves equipped with an analogue pressure transducer the leak test can easily be automatically performed. The leak test is to be performed with an empty chamber. The chamber additionally has to have been warm, for example as a result of a heating program having been run beforehand.

The checking process has its own program button (see program list) which starts with the vacuum system evacuating the chamber. Depending on the equipment of the sterilizer, steam may pass through before the evacuation. The pump in the vacuum system stops when a deep vacuum has been created. For a short period of time after this evacuation a slight rise in the chamber pressure takes place which is not due to leakage but results from evaporation of condensate and temperature-volume changes in the recently rarefied residual steam.

It is therefore not possible to establish that an increase in pressure in the chamber is caused by leakage until conditions in the chamber have stabilized. It is not until about 10 minutes after the pump has stopped that the pressure and time start to be measured.

A satisfactory leak test allows for a maximum permissible pressure rise of 13 mbar / 10 minutes.

With double-ended autoclaves, the loading door opens after a completed leak test either automatically or manually, depending on how it has been programmed.

A Normal vacuum 5 min. B Stabilization of chamber atmosphere 10 min. C Check time 10 min. D Pressure stepping max. 13 mbar.

In certain phases, sensor faults prevent stepping of the program. Stepping may only be done by trained personnel.

Alarm printout in process documentation

Where a main fault causes one or more secondary faults, the operator panel shows on the most recent fault. If the unit has a printer or similar, all faults are printed out, together with the time when they occurred.

Doors

When a fault has occurred, the unloading door of a double-ended sterilizer will not open. Exceptions are errors that occur so late in the process that unlocking of the door has begun.

The door can only b e opened when the corr ect password has been entered. For further information, see the menu description in the Con- trol unit chapter.

Steam generator alarms

Alarms from the steam generator may be due to the operating pr essure being exceeded or the water level in the steam generator falling below the minimum. Low water level may also indicate that the boiler water quality is beginning to be very poor and that the water should therefore be emptied. Call a service tech nician to analyse and correct the fault, with the aid of the description in the Advice and instructions chapter in the TECHNICAL MANUAL.

OPERATION

Error codes

NOTE! Important where a steam generator safety valve has been blowing off for a long time and the chamber is under pressure at the same time. Only switch off the sterilizer control switch as a last re sort, because doing so disables certain safety functions. Instead, call a service technician who can trip the steam generator circuit-breakers.

The error messages listed below are defined in the control system. If more than one error occurs consecutively, only the error code for the last error is displayed.

If the sterilizer is equipped with a printer, the error message is printed out. For secondary errors, all error messages are printed out.

Information about the last twenty faults is saved in the control system and is accessible in the service menu. If the sterilizer has a printer, this information can be printed out.

General advice when using the sterilizer

•

Keep the sterilizer door closed when the unit is not in use.

•

Read the section “General advice on packaging material” in the guide below.

•

If it is difficult to get items dry, the post -treatment stage can be modified. See the guide “Cycle modification according to the type of load” further down.

•

Read the manual for the medical device to be sterilized before starting the process.

•

Be alert to everything that appears unusual such as leaks, humming solenoid valves, stickily mechanical devices etc. Remedy the situation before it becomes a malfunction.

Heating of load

Heating of items to be processed may jeopardie sterilization result due to poor humidification. Make sure appropriate process has been chosen before loading the sterilizer.

34 -

OPERATION

Fire hazard

There have been reports of textile loads catching fire in the sterilizer chamber. In all cases this has been due to the load becoming excessively dry and hot. This can happen in two ways:

•

The load has been placed in a heated chamber and left for a long time without the process being started. Ignition is believed to take place when the load is moistened again on the admission of steam to the chamber.

•

The load is left in the chamber for a long time without the process being completed. This probably happens when the process has been interrupted because of a fault and the load has not been taken out of the chamber. Ignition takes place when the process is completed and the load is exposed to air.

Users should be aware of the risks and establish procedures to ensure that loads are not left in a heated chamber for longer than necessary.

Weekly cleaning - Avanti

External cleaning.

Clean stainless steel surfaces on the outside of the sterilizer with a standard household cleaner that does not contain abrasives. Take care when cleaning painted surfaces, texts, and plastic parts.

Cleaning the chamber

When cleaning inside the chamber, a key switch on the front can be used to block the door open, and shut off chamber preheating at the same time. On double-ended steriliz ers, the same key switch can also be use d to open and block the unloading door for better access; see below.

•

With the sterilizer is in standby mode, turn the key switch to the locked position and remove the key. The text “DOOR KEY SWITCH” appears on the operator panel display.

•

Open the door by pressing the sterilizer cool down before starting work.

Open

button. Let the

OPERATION -

The sterilizer should have cooled down before cleaning. When the key switch cannot be constantly observed, the person doing the cleaning must always take the key with them. This is to ensure that no-one mistakenly resets the key switch.

•

Clean the strainer in the chamber floor drain.

•

Remove any shelves, guides, and bottom plates and clean the inside of the sterilizer chamber. Use a general-purpose chlorine-free cleaner. Scouring powder may be used occasionally on stubborn stains. Never use steel wool. Sterilizers that are often used to sterilize products containing salt require especially thorough cleaning, since residual deposits may even have a corrosive affect on stainless steel. An acidic cleaning agent followed by careful rinsing is most suitable for the purpose.

•

After cleaning, insert the key in the key switch and turn it to the initial position.

•

Bowie Dick testing

The purpose of the Bowie Dick test is to reve al deficie ncie s in the abi lity of the sterilizer to expel air and reveal leaks or an excessive content of non-condensable gases in the steam. In testing in accordance with EN 285, (or applicable national standard) an indicator paper is placed in the centre of a test pack. The pack, which must be 220 - 300 mm square and approx. 250 mm high, must consist of folded cloths of 100% cotton. The pre-treatment of the te st programme must be identical to t he pre-treatment for the processes used for routine sterilization, while the steriliza -

Then close the door by pressing the

On double-ended sterilizers, the unloading door can be opened for cleaning by repeating steps in the points above.

Note! Note that there may be restrictions on door opening on SPF sterilizers and sterilizers with controlled work flow.

When cleaning is complete, both doors must be closed and the key must be left in the key switch.

button.

36 -

OPERATION

tion time may be adapted to the performance of the sterilizer but must not exceed 3.5 minutes.

When the indicator paper has be en sufficiently exposed to steam at a particular temperature, further exposure tends to hide the indication of any deficiencies. GETINGE’s Bowie Dick programme is there fore tested with the shortest possible sterilization time so that any deficiencies are not concealed by overexposure.

In day-to-day work, the above, standardised test packs for the sake of convenience are sometimes replaced by various types of disposable packs which are manufactured by a large number of manufacturers. As these packs are generally even more sensitive to overexposure than the standardised test pack, it is extremely important to c hoose the correct make. Test packs in accordance with BS 7720 :1995 must be used for GETINGE’s Bowie Dick programme.

Approved consu m ables

Consumables are used for different purposes as packaging for goods to be sterilized, for testing, for replacement of sterilizer parts with limited life or a sterilization media for low-temperat ure sterilizing. The list of consumables below is intended as a guide to be used with GETINGE’s CE-marked sterilizers.

Always check whether consumables have a use-by date before using them.

Articles for packing items to be sterilized

Packaging materials must be matched to the method of sterilizing, the load carrier and the goods to be sterilized. To guarantee compatibility with GETINGE sterilizers, it is the responsibility of the user to ensure that packaging material and methods used conform to European standard EN868-1, the other parts of which also specify particular requirements for different types of packaging material.

Packaging material for steam sterili zation

Getinge AB recommends warping in paper for textile packages and for instrument grilles in baskets and containers.

Getinge AB recommends paper/plastic bags for separately packed articles.

OPERATION -

Packaging material for formaldehyde

For formaldehyde sterilizing, we recommend pape r/plastic bags intended for steam sterilizing.

Articles for test purposes

The user is responsible for maintaining a routine check of the operation of the sterilizer in accordance with European standard EN17665. There are various types of test articles on the market to assist the user.

Chemical indicators

Chemical indicators used when testing various types of sterilizer must conform to European standard EN867-1, the other parts of which also specify particular requirements for different types of indicator.

Getinge AB recommends using chemical indicators in steam sterilization processes. For other types of processes it the user’s responsibility to evaluate whether individual makes are applicable to the GETINGE sterilizer process.

An established test method in which chemical indicators are used is the Bowie-Dick test, with test packages or its equivalent with a disposable package. For information see also under “Bowie-Dick testing”.

Biological indicators

Biological indicators used when testing various types of sterilizer must conform to European standard EN866-1, the other parts of which also specify particular requirements for different types of indicator.

Getinge AB recommends using biological indicators in steam sterilization processes. For other types of processes it the user’s responsibility to evaluate whether individual makes are applicable to the GETINGE sterilizer process.

Sterilizer parts for periodic replacement

Spare parts

So that correct operation and product safety can be guaranteed, parts for recorders, printers or periodic maintenance must be genuine GETINGE spare parts or parts approved by Getinge Infection Control. Article numbers of genuine parts are stated in the relevant sections of the service manual.

Sterilization media for low-temperature sterilising with formaldehyde sterilizers

Low-temperature sterilizing can only be done with special sterilizers intended for the purpose. During sterilizing with formal dehyde, the medium is added from containers attached to the sterilizer.

38 -

OPERATION

Formaldehyde solution

Containers holding formald ehyde solution are brought to the site an d attached to the sterilizer by the operator.

Accessories

Where relevant, details of concentration, volume, packaging, handling and properties are described under Operating instructions and under “General advice on formaldehyde sterilizers”.

The sterilizer's CE label makes the manufacturer responsible for ensuring that its product safety and function satisfies the strict requirements laid out in the relevant EC directive. Accessories that are mechanically, electrically or otherwise connected to the ster ilizer must be compatible with this. As a result, only equipment that has been evaluated by Getinge AB and registered as approved equipment may be used together with the sterilizer.

Should non-approved equipment be used, Getinge AB exempts itself of all product liability for the sterili zer and its CE label.

Approved accessories

The accessories listed below are compatible with the sterilizer once the sterilizer has been configured to function with the a ccessory in question. Such configuration shall be performed by a professional authorized by Getinge Sterilization AB.

OPERATION INSTRUCTIONS -

Goods handling

Remember that the goods may contain a c onsiderable amount of heat when unloaded. Position them with regard to a good working environment.

Note that the goods may be very hot immediately after unloading. Let the goods cool down or wear safety gloves to handle them. Long sterilizers can take two load carriers in a row. Use a hook (ordered separately) to reach into the chamber and extract the inner load carrier.

Things to do when the work is finished

Unless otherwise prescribed by local rules:

•

Turn off the control power supply by the switch on the front.

•

Inspect the strainer in the bottom of the chamber and clean it if necessary.

•

Close valves for air, water and, if used, steam and gas.

If necessary:

•

Shut down the sterilizer for long enough to let it cool down, eg overnight.

•

Clean the inside of the chamber. Use a chlorine-free cleaner if necessary.

The sterilizer must always be cold when cleaned. To prevent injury, switch off the power to the control system.

The cleaning instruction is given in the section “General advice on using the sterilizer” in the Operation chapter.

OPERATION INSTRUCTIONS

To interpret the “Finished cycle” indicator

Normal routine cycle:

After completion of fault-free normal routine cycle, the indicator shows a steady green light.

Maintenance cycles:

After a completed, fault-free automatic leakage test or filte r sterilization, for example, the indicator shows a flashing green light.

Normal routine program: On the completion of an error-free routine process, the panel lights up green and an acknowledgement key lights up. (Does not apply to automatic loaders)

Normal routine cycle with fault:

After completion of stepped or alarmed normal routine cycle, the indicator shows a steady red light.

Maintenance cycles with fault:

After completion of a stepped or alarmed maintenance cycle the indicator shows a flashing red light.

Stopping the program or a blowing safety valve

In an emergency, the program can be stopped or a safety valve that is blowing off can be made to close, by means of the EMERGENCY STOP button on the front panel, without disabling the safety systems of the unit. An alarm is triggered when the program is stopped.

•

Press the EMERGENCY STOP button.

•

Follow the instructions under “What to do if there is an alarm” below.

Only switch off the control unit power switch as a last resort, since this affects t he safe ty sys tems of th e installation.

The main power supply switch or disc onnector to the st erilizer may be turned off only in an emergency.

OPERATION INSTRUCTIONS -

On power failure or if the control switch or working switch of the sterilizer had to be turned off during a process, there is a risk of leakage at the door. Safety measur e when there is positive pressure in the chamber:

KEEP WELL AWAY FROM THE DOOR AND CALL A TECHNICIAN!

ALWAYS LEAVE THE PREMISES and call a technician if the chamber pressure is in the RED area of the pressure gauge.

Measures in case of alarm

Programs that are installed to be ended automatically

•

The program ends automatically.

An emergency stopped process or program that did not finish automatically.

•

Note the process phase during which the fault occurred.

•

Silence the alarm signal by pressing

OPERATION INSTRUCTIONS

CONTROL UNIT PACS 3500

The letters PACS stand for Programmable Autoclave Control System. The purpose of the control system is to issue orders and send them to

the executive components of the unit so that a number of process steps are performed in accordance with a pred eterm ined tem plat e. The orde r signals are worked out by the computer program of the control unit in conjunction with measurements of actual parameter values for the current program. These are usually times, temperatures and pressures.

Several different pieces of equipment can be connecte d to the control unit for programming, monitoring and documenting the processes.

The operator communicates with the control unit via a control panel or an ordinary PC. There are several versions of the operator-machine interface, from the simplest, which consists of two pushbuttons and eight LEDs to show that certain statuses have been reached, to the most advanced, which allows complete programming of the control system, among other things.

All operator panels are manufactured to monitor the processes by displaying all the set parameter values as well as actual values on request. All relevant data associated with a given process, such as cycle number, operator number, date, etc., can be entered by the operator.

Programs, system definitions and process data can be documented by connecting a printer to the unit. A host computer can also be connected directly to the CPU of the control system.

If necessary, a measurement and monitoring system which is completely independent of the control system, can be set up by providing the equipment with a SUPERVISOR. This contains a separate CPU and its own measurement and control boards. The SUPERVISOR performs its measurements by means of separate temperature and pressure sensors alongside those of the control unit. The system has links to the control unit CPU and can therefore use the shared operator panel, as well as adding the c ontrol unit readi ngs to the process documentation. The SUPERVISOR can also be involved in independent interlocking of door opening, for example.

The computer contains programs for automatic calibration of the temperature and pressure sensors. Where alternative correction constants are known, they can be entered manually. The testing functions include means of activating analog and digital outputs and for monitoring analog and digital inputs.

The control unit hardware is divided, so that the operator panels can form small separate units that are easy to position at the most suitable location. CPU, measurement and control boards and the power supply are installed in separate electrical enclosures which are connected to the operator panels by shielded cables.

A number of special terms

STERILIZATION refers to the entire series of treatments that make up a process aimed at achieving the total killing of all living organisms. This applies to sterilizers and usually includes air removal, heat treatment and a drying phase.

STERILIZING refers to the actual killing part of the process, the heat treatment.

On the same basis as the two terms above, STERIL IZATION TIME refers to the duration of the entire process from the start until the obje cts can be taken out of the sterilizer. The PROCESS TIME is the same as the sterilization time.

The STERILIZING TIME is only that part of the process for which the programmed STERILIZING TEMPERATURE exists in the chamber.

In this context, PARAMETERS means FACTORS THAT I NFLUENCE THE sterili zatio n pro cess . Ex amples of p aram eters in th e ster ilization process are temperature, pressure, time, humidity, gas concentration, etc.

PARAMETER VALUES may be permanen tly set in the program, be adjusted by the operator, be included in selectable recipes or downloaded from a higher-level system.
