1 INTRODUCTIONThis Service manual is valid for SELECTOMAT SL models and it contains the summary of data concerning the product, necessary to make the repair works, maintenance and device check.It assumes knowledge of both the Instructions for use, written as a separate document, and annexed connection diagrams.

2 DESCRIPTION OF THE UNIT

The SELECTOMAT SL unit belongs on the category of large steam sterilizers. It is designed to be used in the health service facilities, in central sterilization stations, in the hospitals and generally in all branches where sterile goods are used.

2.1 STERILIZER CHAMBERIn the sense the sterilizer chamber is a pressure vessel. Another standard, holds for operation, maintenance, revisions and tests of pressure vessels.The chamber is made from chrome-nickel-molybdenum stainless steel of grade AISI 316L and ASI 316Ti. The inner surfaces of the chamber are surfaced. The sterilizer chamber is closed by a vertically slidable, electrically or manually operated door. The door and chamber are thermally insulated with mineral fibre (thickness 50 -130 mm).The door and the chamber are thermally insulated by mineral wool. An electrically operated door is fitted with a protective bar with four switches situated under the door cover. The door drive coupling is adjusted to develop a force of 150 N when closing the door. A manually operated door is fitted with a locking magnet with respective position switches avoiding opening the door in case that the pressure in the chamber has not yet reached the atmospheric level. The basic sealing element of the door system is a hose-like seal put into a groove in the vessel. After starting the program, the seal is pushed against the door by steam pressure, what secures tightness between the vessel and the door. After finishing the the program, the seal is pulled back into the groove by vacuum. In models 666 – 6612 the left pair of the door travelling rollers is fitted with an excenter for adjusting the clearance between the guide bars.The sterilizer chamber is provided with two test connections with pipe threads ISO 228-G1/2 A and G1-A allowing to introduce checking sensors into the chamber. The chamber contains shelves for placing the goods being sterilized, or a multi-story frame for the model BW loading trucks.

2.2 STEAM GENERATORThe sterilizers are delivered in three variants FD, ED, FED. The built-in electric heated steam generator (variants FD, FED, or possibly FDT) is designed to generate clean steam from completely demineralized water. The generated steam shall not contain hydrazine (N2H4) or other volatile, corrective chemicals and corrosion inhibitors.

The steam generator may be supplied only with respectively treated, totally demineralized water. A treatment on the principle of reverse osmosis is duly recommended.The power input as per sterilizer models amouns to:446/636 22,5 kW666 36 kW669/6612 45 kW9612 63 kW9618 72 kWThe steam generator is made from chrome-nickel-molybdenum stainless steel of grade ASI 316Ti.The boiler is fed by means of the feeding pump from a storage tank with controlled water level. The water level in the boiler itself is controlled by level switches.There is a double protection of the heater elements. The lowest permissible water level NW is secured by the safety level switch B91 (locking the switching-on of heating power). The operational height of the water level is maintained by the level switch B90, having also a protective function. In case that water has not been refilled within a certain time limit (approx. 40 s), the heating power is reversely switched off. The control of the steam generation is performed by a pressure gauge in dependence on the steam pressure. Excessive values of the steam presure are avoided by built-in safety pressure limiter. The heater elements are switched on and off successively in blocks with approximately 1s delay.

The “G” type liner is set “more sharply” (near the temperature/steam pressure balance) and it is therefore dedicated for traps connected to the outlet from the sterilisation chamber (now newly also for the direct trap of the steam/steam exchanger - FDD).This liner is not so much suitable for condensate draining from jackets as the draining is too rapid, noisy... in some cases.The “E” type liner is set to “standard” (i.e. a little bit under the balanced state, than the previous type) and it is dedicated for other traps, where the softer drain is required. E.g. the condensate drain from the jackets, supply pipe etc.This liner is not suitable for the chamber, as it drains the condensate for this not enough purpose and it can cause a distortion of the measured temperature on the main PT sensor, problems with the residual air, non-condensed gases etc.The liners are mechanically changeable and it is necessary, during the replacement, to replace them by a suitable type and with certain knowledge.

2.4 COVERAGEThe unit is covered with stainless panels of 1.4301 material quality. there is also a lockable service-door in the covering.

2.5 ELECTRIC CONNECTION

2.5.1 BLOCK DIAGRAMThe apparatus is controlled with micro processor automatics. From the following chart it is obvious the basic arrangement of the electrical equipment of the apparatus:

The basic interface „attendance – apparatus“ is the contact panel on the loading side of the sterilizer, which is controlled with the processor MASTER. This processor also ensures the contact with peripheries (PC, printer, chip-card, MMC).In the unloading side there is a smaller contact panel, which is controlled with the processor BACK.Further the apparatus contains the processor SLAVE, which processes the information from the digital (switches) and analog (temperatures and pressures) of inputs and controls the outputs.In order to secure the safety as well as in the case of a failure of the processor SLAVE, the apparatus contains a block of hardware protection, which is controlled with the processor MASTER and some inputs (see the chapter of hardware protection).

2.5.2 DESCRIPTION OF THE ELECTRIC CONNECTION DIAGRAM

The electric connection diagram is in the supplement of these instructions.The connection diagram is attached to these Instructions. The following page numbers correspond to the diagram Z468466 v.14 and diagram Z471105 v.4 (UL variant). In higher versions, the numbers can differ.

The connectors XP3 and XP4 serve for interconnecting of the sterilizers between them (control of consumption). If the cables are connected to both connectors, the switch S1-2 must be in position „OFF“, if there is connected only one connector, S1-2 must be in position „ON“.

2.5.2.3 FRONT PANEL (ON THE LOADING SIDE)Pages 6, 7 and 14 show the interconnection of the individual front panel elements.The tiltable panel for the SELECTOMAT SL models consists of the touch panel glued by a double-sided adhesive tape to the display, of the VP_M_LB121 board, inserted into the display, of the converter for CFL (display illumination) and of VP_CPUM (MASTER) processor board, for the SP HP E and SP HP S models it consists of the touch panel with display (one part), of the VP_LVDS board, of the converter for CFL (display illumination) and of VP_CPUM processor board. On the rear side of the front panel, the VP_KON connector board is placed and the chip card reader, printer and servo (for SELECTOMAT SL models) are connected to it.When making connection of the servo it is important to take care of the position of the black wire – see the diagram. Furthermore on it there are connectors for connection to PC (RS232, USB and ETHERNET). To the connectors XS1 and XS2 it is led out the internal busbar RS485. If the cable is connected only to one of them, it is necessary that the both two switches S1 (beside the connectors XS1 and XS2) would be in position „ON“, otherwise both the switches S1 must be in position OFF.To the connectors XS1 and XS2 of this board it is led out the internal busbar RS485. If it is connected only the cable only to one of them, it is necessary that the both switches S1 (beside the connectors XS1 and XS2) would be in position „ON“, otherwise both the switches S1 must be in position OFF.If the VP_CPUME.. processor panel is used in SP HP E or SP HP S models, it replaces the VP_CPUM, VP_KON and VP_LVDS panels – see page 14.

2.5.2.4 REAR PANEL (ON THE UNLOADING SIDE)In the sheet No. 9 and 10 it is drawn the mutual interconnection of the respective elements of the rear panel.The rear panel consists, for SELECTOMAT SL models,of the touch panel, display, converter for the display illumination and VP_CPUB processor board, for the SELECTOMAT SL models only of VP_CPUBE processor board. The internal RS485 bus is brought on the XS1 and XS2 connectors of the processor boards. If the cable is connected only to one of them, it is necessary that both S1 switches (close by XS1 and XS2 connectors) are in the “ON” position, otherwise, both S1 switches must be in the “OFF” position.

2.5.2.5 INPUTS

2.5.2.7 HARDWARE PROTECTION

Due to safety purposes the outputs, which in case of undesirable switching can endanger the user, or possibly to damage the apparatus, are blocked by means of the relays, which are switched with the switches being independent to the automatics of the apparatus. The connection of the relay coils is obvious from the sheet No. 9. The appropriate contacts of these relays are represented in the sheets No. 10 and 11.The moment, when it is possible to switch the outputs, is obvious from the following table:Name of the output

transition to the initial state from the master, i.e. in the chamber it is atmospheric pressure and the slot will be de-sealed. The processor back receives from the attendance of the apparatus the instructions for the requested activity and hands over them to the processor master, which further processes them.

2.7 LOADING OF BIOS, APLICATIONS AND LANGUAGES

For recording – download of the software equipment into the sterilizer the program „Loader.EXE“ serves. Software is transmitted on the serial line RS 232 z PC by means of the cross cable:

Cannon 9 female

If we want to download the software, then we start the program „Loader.EXE“. on the upper bar we select with a mouse the file „File->Open the file“ and choose the file, which we want to download. On the surface of the program there will appear a window with the listing of the program. (The files are marked in a mnemonics manner such as BiosMltMst…). Then on the upper bar we select „Download->Load the file/process the batch“.When starting the download it is necessary that the window with the listing should have a blue bar. After starting the download it is possible to switch over the window. But it must not be closed.

2.7.1 LOADING OF BIOS Bios is loaded into every processor board separately (VP_CPUM, VP_CPUS, VP_CPUB). For this purpose each of these boards has a connector for connecting of a serial line RS232 (for VP_CPUM it is located on the board VP_KON). With respect to the fact that the switches, which enable to load the Bios, are located on the boards of electronics, before its loading it is necessary to uncover the boards. In loading the bios there is erased the processor memory, in which there are stored all the information on the apparatus (apart from the system version), therefore it is necessary, before you record – load the bios on the boards of electronics VP_CPUM, to backup the following information (see. print,…):- Configuration of the device



and the Slave takes place via RS485 bus, fully controlled by the Master. In moments, when the situation asks for, the Master sends required data to the Slave, in reverse direction pieces of periodically sampled information are transferred in form of data packets with fixed structure.If the apparatus is the two door type, to the busbar RS485 it is connected another microprocessor (back), which ensures the control of the apparatus form the side of the material unloading.

The following table shows the access of both microprocessors to the peripherals.Access to external initiation or possibility to perform activity

Software of the apparatus has two main layers, BIOS and APLIKACE. BIOS ensures the communication between the appropriate processors. And further the upgrade of the application.The application ensures the correct function of the sterilizer. The processor master receives the instructions from the attendance for the requested activity and at the same time for the control it assesses from the processor slave the states of sensors, values of measured variables and also the information regarding to the fact, within which phase of sterilization cycle the process is found. Many of necessary data are obtained independently, or it compares them to the parallel obtained data from the slave. If the attendance gives instruction to the commencement of the activity, the master sends in direction to the slave the packet of necessary parameters. The processor slave is entrusted the course of the sterilization cycle on the basis of the information from the processor master. Slave has a direct access to the outputs (valves, contactor, ...) and to the inputs (thermal and pressure sensors, switches, ...). If the slave detects the error, it notifies of the fact the processor master and freezes its activity, i.e. all the action variables take up the safe state and it is waiting. Only after deleting the error by the attendance the slave receives the instruction to

The pressure is scanned by the pressure gauge PE20. The back-flow valves V13 are fitted only within the version FED. After starting the sterilization program the door is sealed via the valve Y09. The pressure under the seal is checked by pressure switch B20. There is started the vacuum pump VY1, which via the valve Y20, filter F4, cooler CHL and the back-flow valve V12 exhausts the air from the working space. The pressure in the chamber is scanned by the pressure gauge PE1.1 and PE1.2. After gaining the necessary under pressure the valve Y 20 is closed and it is opened the valve Y07, through which the steam is filled into the chamber. The condensate trap O2 realizes the condensate exhaust from the chamberse. In an analogic way, the sterilization cycle proceeds till the phase of pressure releasing, when the steam is intermittently discharged from the chamber via the cooler CHL. Cooling water is supplied into the cooler via valve Y30, filter F6 and flow limiter P1. Water is further supplied into the cyclone and via an orifice plate it feeds the vacuum pump VY1. Excess water flows away via the overflow. The temperature of water in the cyclone is scanned by a PT2 temperature sensor.In case that the water temperature is lower than the preset value, the valve Y30 in some phases of the sterilization cycle closes and the vacuum pump is then feeded from a closed circuit to save water. It is possible to set the controlling temperatures within the automatics.Valve Y80 opens when aerating the chamber. The air flows into the chamber via bacteriological filter F1 and non-return valve V10. Steam is sucked off the groove in the door by vacuum pump VY1 via opened valve Y23, filter F5 and non-return valve V12.Compressed air for pneumatic valves is reduced onto approximately 5 bar pressure by the reduction valve V3. Temperature in the chamber is scanned by double sensor PT1.1, PT1.2. The condensate from the jacket I is conducted via the filter F3, condensate trap O1. The condensate from the jacket II is conducted via the filter F103, back-flow valve V111, condensate trap O101.Additives:-Solution program with self-cooling.Within this version in addition to the device is fitted with a movable sensor PT3, which indicates the temperatures of solutions in the reference bottle. The valve Y50 blocks the condensation valve O2 in case of the started solution program – in the phase of cooling down.-Bacteriologic filter - decontaminationWithin this additive the device is supplied with the bacteriologic filter FIL1. The valve Y02 for lower steam filling into chamber – sterilization of condensate. Another valve is the valve Y21 for the condensate exhaust after the sterilization exposure and evacuation of the chamber.

Sterilizer may be alternatively equipped with a series of other additives:• Forced cooling with the air counter-pressure • Independent control of doors• Sterilisable filter (air vent)• Monitoring of media• Waste aftercooling• Air Detector etc.

3 FUNCTION OF THE UNIT

3.1 PIPING DIAGRAMIf within the automatics it is activated the generator, the pump C1 refills with demineralised water into the generator from the storage tank via the filter F7, back-flow valve V14 and valve V7. Reaching the necessary level is secured by the level switch B90. After starting the generator the heater elements TT begin to heat. The boiler is brought onto the operating pressure, which is being scanned by the pressure gauge PE3. The valve Y99 opens for approximately 2s after every water refilling to decrease concentration of salt in the boiler. The level switch B91 secures protection of the heater elements. The pressure switch B31 serves as protection against overpressure. Valve V6 is used for manual mud discharge from the boiler. The generator is equipped with thermal degasification of the feed water. Water in the storage tank is heated by a heating coil. Heating is regulated with the valve Y150. The temperature of demineralised water is scanned by the temperature sensor PT5. The minimal level of demineralised water in the storage tank is scanned by level gauge B86. In case of shortage of water the feed pump C1 is blocked.

After selecting the sterilization program the steam of the heating jacket I is filled via the filter F2, valve Y03 for the pressure being set by the selected program. The pressure is scanned by the pressure gauge PE2. Into the jacket II the steam is filled via the valve Y103.

4.1 MENU - SETTING AND SERVICES ACCESSIBLE FOR THE UTILITY TECHNICIANS

The menu enables for the utility technician a detailed setting of the apparatus test of safety elements, controlling of the appropriate outputs independently on the automatics and other functions, which are not accessible for the attendance.In this chapter there are described only the functions, which are not described in the instructions for use.Most of changes, which are described in this chapter, require the entry into the internal memory of the apparatus.

This will occur after pushing the return button . And after confirming this operation by pushing the button “Store”

For the period of storage the apparatus does not react to the touch contact.If you are not sure that you have performed the mentioned operation correctly, please, push the button „Do not store“, by which you will arrive at the screen by one level higher, or push possibly the button „Cancel“ for the return to the set screen.If it is possible to set the mentioned parameter only on certain limits, these limits are indicated in the brackets. In order for the inactive buttons to become the functional ones, it is necessary to log in the following manner:

- To push the button

- The screen appears:- into the line marked as “Jmeno”, write the name,

assigned by the service MMM department, e.g. serv001 (the line is activated by the touch)

- into the line marked as “Heslo”, write the assigned twelve-character password.

- pushing the button

4.1.1 TEST OF SAFETY ELEMENTS After pushing the button „Test of safety elements“ there appears the screen:

- By pushing the button „K60+K61“ it is possible to verify the functionality of the relay K60 and K61, which in case of a critical error will disconnect the supply of outputs (see the connection diagram).





- Function of the safety pressure switch B31, which creates the independent protection of the generator, can be checked by pushing the button „B31“. There appears the screen:

Push the button „GENERATOR“ – the generator works in normal mode, i.e. it regulates the pressure within the set pressure values (see the setting of the apparatus). The actual pressure value is displayed by a colour column and concurrently in figures in the left upper part of the screen. After attaining the upper pressure limit of the generator (in this case 370 kPa) push the button „GENERATOR++“. By this the generator is switched on for the period of 9 seconds, which is indicated by the number beside the button. At the moment, when the pressure switch B31 disconnects, the screen will appear with the message „Pressure switch of the generator“. Pushing the button „OK“ you will arrive to the preceding screen se, in which there was changed the message „B31 without pressure“ to „B31 Under the pressure“.In the case that B31 will not disconnect within nine seconds, again push the button „GENERATOR“.On the screen there are also the information on the fact, in which state there are the inputs and outputs being necessary for the function of the generator.If it occurs that sooner than B31 activates the safety valve, it is necessary to adjust B31 to lower pressure, or to replace the defected safety valve or the B31.- Functionality of the bottom level gauge of the generator

can be verified after pushing the button „B91“. Proceed according to the instructions described on the screen. After confirming one step, the following one will automatically highlight.

4.1.5 SETTING OF THE DEVICE

4.1.5.1 SERIAL NUMBER AND CHARGES COUNTER

The serial number and charges counter are set during the equipment production and the serviceman does not have any right to change them. These data are stored on up to nine independent places in the electronics and therefore they are not lost in case of replacement of individual boards.

4.1.5.2 OFFSET OF PRESSURE

Pressure sensor offsets are set here:

You can choose either one-, two- or three-point offset. The one-point offset is set in the extreme only if you do not have the device for pressure sensors setting.The two- and three-point offset is set in the following way:Use the arrows to select the appropriate pressure sensor. Press the Point A button and insert the pressure of the first measurement. Then press the Offset A button and insert the measured deviation including the sign. Proceed in the same way for points B and C.Proceed equally for other pressure sensors.Offsets are measured in the following way: The sensor is screwed off the device (it remains connected electrically to the device) and is connected to the calibration vacuum pump (recommended vacuum of 10 kPa). The difference calculated as the set value minus the pressure on the device without offset is the resulting offset. Repeat the procedure with the sensor connected to the calibration pressure air pump on which overpressure is set (205 kPa is recommended).If you do not have the possibility to measure the offsets and you still have to measure them, use the Preset button. After you press this button, the offsets of all pressure sensors will be set to the basic values.

Store the change by pressing the return button It is recommended to check the pressure offsets during the annual device overhaul.

4.1.5.3 OFFSET OF TEMPERATURES

Offsets of temperatures are set similarly as the offsets of pressures. Temperature offsets are measured similarly to the pressure offsets.



4.1.5.9 SERVICE PLANNING (NEXT MAINTENANCE) This service allows the service technician to plan the service in detail.The device then notifies of an up-coming service activity by means of a message displayed on the screen, or of not meeting the deadline for a preset service activity, if any, by means of a printer output (in the report heading).Up to 15 service activities can be planned (in 5 groups), both according to the time or number of batches processed, either separately, or according to an earlier achieved criterion.• Press the button Menu / Device Setting / Next

If not a single page is On, the function of service activities planning will be disabled at all.In the Service Activity Timing field, select the time or batch criterion, or both criteria together.The Was Set buttons set the initial state of the criterion in the moment of setting; the Interval buttons set the appropriate interval between the service activities.By means of the Notification buttons, you can set the number of days/batches by which the device will notify the operator in advance of the upcoming day of a given service activity.The “speaker” symbol shows the active state of a notification. (The appropriate notification for the operator of the upcoming service day has already been displayed.)The Preset button will reset the actual Next Maintenance page.

The service activity can be defined on the individual lines in the field Service Activities Description. If all three description lines on the page remain empty, the page will be excluded from the service activities planning function.The field Will Be Performed Exceeding shows any potential not observing (exceeding) of a specified date / batch number. (The specified dates are displayed in the field Service Activity Timing in the Will Be Performed indicator.)

Note:Information about the specified maintenance date not observing will also be shown in the printed cycle report!

The only difference is that the PT sensor is inserted in a dry calibration oven (recommended calibration temperature: 121 and 134 °C).It is recommended to check the temperature offsets during the annual device overhaul.

4.1.5.4 SETTING THE DOORS

This selection is accessible only in case of the two door device and it is possible to set one of the three selections:- Selection „12“ sets the door on the side of the main panel as to be strictly loading one and the other door as to be strictly unloading one, it refers to a classical configuration of the two door version, automatics watch the logics of opening the doors.

- Selection „21“ sets the door on the side of the main panel as to be strictly unloading one and the other door as to be strictly loading one, automatics watch the logics of opening the doors.

- Selection „XX“it is not determined, which side of the device is loading one and which the unloading one, automatics do not watch the logics of opening the doors, it is only secured that both the doors cannot be opened at the same time.

4.1.5.5 UNITS

Red button contours show the button position on the touch panel stored in the device memory; the green contours show the position actually being set. It is recommended to set the offset according to the central Test button.

Store the change by pressing the return button

4.2 REPLACEMENT OF THE PARTS OF ELECTRONICS

4.2.1 REPLACEMENT OF THE ELECTRONICS BOARDS

The appropriate electronics boards are obvious from the connection diagram, sheet 4-6 and their order numbers from the spare parts list. In case of their replacement it is necessary to observe the following:1. Before the replacement of the board VP_CPUM it is

necessary to backup:- The setting of the device- Configuration of the device- OffsetsThis information is included in the test report, which is delivered with the equipment. In case that the serviceman changes any parameter, it is suitable to print and store the changed parameters immediately.

2. In case of replacement of the VP_CPUM, VP_CPUS and VP_CPUB processor boards, it is necessary to record there a SW compatible with other boards inclusive bios (the activated board has still recorded bios, therefore it should be overwritten only if an older version is stored on the board).

3. After the replacing and programming the board VP_CPUM it is necessary to perform:- The setting of the device- Configuration of the device- Setting of the offsets


If it was not possible to read it from the replaced electronics board VP_CPUM, it is necessary to obtain the information from the documentation for the mentioned device.

4. After replacing and programming of the board VP_CPUS it is necessary to store the configuration of the device and offsets of the pressures. In this operation there is not set anything – by performing the storage, the data from the memory of the board VP_CPUM are copied into the memory of the board VP_CPUS.

5. When replacing the other boards of electronics there is not set anything.

6. If it is necessary to replace more boards, they must be replaced gradually and the equipment must be turned on after the replacement of each board!.

4.2.2 BATTERY REPLACEMENTThe battery is placed in the electronics board VP_CPUM (VP_CPUME). It is necessary to replace it, if its voltage decreases to the value of 2.7 V. Before its replacement, please, write down the state of the batch counter. Set the date and time and all user settings (language, colour palette, …) after the replacement.

4.2.3 REPLACEMENT OF THE CONTACT PANEL - FRONT PANEL

The contact panel is glued with a bonding tape into the frame of the hinged panel. The contact surface is on the side of the strip tap, this is inserted into the viewport of the frame. When replacing the contact panel first it is necessary to glue a bonding tape into the frame and then to insert it in such a method so as the active surface of the contact panel would not touch the bonding tape (The active surface is transparent).Further the bonding tape is glued on the other side of the display and on its other side there is left the cover foil (this tape serves for sealing between the contact panel and the display). The display is laid on the contact panel without gluing and it is screwed by means of the raising posts to the frame of the hinged panel.

4.2.4 REPLACEMENT OF THE TOUCH PANEL AND DISPLAY - REAR PANEL

The contact panel is glued with bonding tape to the display. When replacing it first it is necessary to separate by scalpel or a thin knife the old contact panel from the display and then to glue a new contact panel so as the active surface of the contact panel would cover with the active surface of the display.After the replacement of the display, the display may not be legible due to an inappropriately set contract. The contrast can be adjusted roughly by pressing the right upper (contrast increase) or left upper (contrast decrease) corner of the touch panel just after the device switching-on (a clock is displayed). Fine adjustment is carried out after pressing the Menu and Contrast buttons.

4.3 DEFINITION OF THE PROGRAM PARAMETERS

4.3.1 THE WAY OF DEFINITION OF THE PROGRAMME PARAMETERS

The automatics of the SELECTOMAT SL unit is designed so that the actual courses of the individual sterilization programmes are defined in every ready made unit by means of hardware and software tools.Hardware tools:

computer compatible with the IBM PCinterconnecting cable

Software tools:UNICONFIG.EXESet of templates xxx.sab- KlasicCykl.sab (for sterilization data files *.bp1)- Roztoky.sab (for sterilization solutions data files *.li1)- Air detektor.sab (for AirDetector data files *.ad1)- Vakuum test.sab (for vacuum test data files *.vt1)- Unicrash.sab (for UNICRASH data files *.uc1)- Data files

UNICONFIG.exe, templates and data files must be in one directory! The actual form of the program is defined in the following method:By means of the mentioned-above procedure in the device in the menu „Menu“, to select „Download of programs“ and confirm. Then it is necessary to set the program, which we want to alternate. In case of PC it is necessary to proceed as follows:To start the program UNICONFIG.EXE. To select the menu „File->Open“, to open the directory, in which there are stored the appropriate data files, in the line „files of the type“ to select the correct type of the file, to choose the required file (it must appear in the line „name of the file“) and to push the button “Open”. On the PC screen there appears the definition field with parameters. By means of the cursor arrows, or by means of the mouse, the appropriate parameters are selected and then they are modified. The key Enter in general opens the dialog window for editing the value of the selected parameter. A double click on the left pushbutton of the mouse substitutes the key Enter.The tabulator changes the active column of parameters. A finished packet of parameters can be stored on the computer disc.By this there are defined the files of concrete parameters, how they are referred to in the paragraphs about software aids. If we should define a program, we select within the program UNICONFIG.EXE menu „Communication->Data export”. By confirming the program is transferred to the device and there is set the following program. After downloading the programs it is necessary to store the changes. For the transfer it is possible to utilize also the icons on the auxiliary bar.Warning: The parameter changes may unfavourably influence the sterilization cycle and therefore they may be changed only by the authorized person. For this purpose it is better to utilize only the programs created in the manufacturing plant. The manufacturing plant does not hold any responsibility for the damages caused by improper setting of the parameters.

4.6 AIR DETECTOR The Air detector itself is within the diagram of the piping connection of the device. To the Air detector there belongs a pit with the temperature sensor PT6, valve Y27.Air detector works automatically and in case of possible exceeding the limit value of the non-condensed gasses in the sterilizer chamber, it will report the appropriate error reporting, which interrupts the sterilization cycle.(A condition for the Air detector functionality, similarly as in case of other additives, is the configuration in corresponding service.)

In the service of the Air Detector it is possible to set:• Sterilization programs, within which the Air detector is

active. • Modes of the Air detector

Working mode – principal function mode Testing mode without error – it is the auxiliary testing mode, when during the started sterilization cycle there is open the auxiliary valve Y28. Within this mode into the chamber it is sucked a defined amount of the additional air via the hand adjustable butterfly valve V100 as to verify the proper function of the Air detector.Within this mode the Air detector does not report the appropriate error reporting so as the cycle could continue and it would be possible to assess for example the influence of the air on the temperature distribution in the testing packet.Testing mode with error – it is the auxiliary testing mode, when during the started sterilization cycle there is opened the auxiliary valve Y28. Within this mode into the chamber it is sucked a defined amount of the additional air via the hand adjustable butterfly valve V100.

• Setting of the Air detector – setting of the air penetrationClose the door of the sterilizer.



Push the Start button.

The sterilizer performs the evacuation and after a short stabilizing pause it is measured the increase of pressure in the chamber in dependence on the setting of the butterfly (vacuum breaker) valve V100.The pressure increase is continuously displayed in the shape: momentary value/ average value (kPa/min).In case of need it is possible to repeat the measuring cycle by repeated pushing the button Start.The initial value for the setting of the air penetration is 1 kPa/min.The total setting of the Air detector, see EN 285.Additive - the vacuum breaking valve for the setting of the air penetration via the valve Y28 and the butterfly valve V100 has order number: R469696. This additive serves only as the auxiliary device for more comfortable setting and thus it is not necessary for the function itself of the Air detector.The additive of the vacuum breaking valve (R469696) is connected into the orifice„VT“ of the sterilization chamber.Note: For start of this auxiliary program for measuring (setting) of the pressure increase it is necessary to have downloaded the appropriate program in the device. (Air Detector.ad1).• Assessment temperature – enables to set the decisive

temperature of the Air detector.The increase of the decisive temperature it is increased the sensitivity of the Air detector and vice versa (orientation range 50 -100 °C).
