About this Service Guide

This STATIM service manual was created to act as reference for the service and repair of the STATIM brand. In the interest of providing one comprehensive global service manual, this book references both the STATIM 2000 and the STATIM 2000S models. Because of this, you will note that there are chapters and sections that do not apply to the STATIM unit that you may have, or are repairing.

If you have a question about the unit you are repairing, please do not hesitate to contact your local SciCan representative for conﬁrmation.

Hazardous voltages are accessible when the cover is removed. Disconnect the power cord before servicing the power mains portion of the controller board and associated devices.

If the cover is removed, a dielectric strength test (Hi-Pot) AND a protective bonding impedance test (ground continuity) must be performed on the STATIM when the work is completed and after the cover has been returned to the unit.

The STATIM is heavy. Exercise caution and seek assistance when lifting or carrying the units.

Use only steam-process distilled water in the STATIM.

The STATIM contains electronic circuitry that is static sensitive. Always wear a static strap when working with or near printed wiring boards. In addition, use static footstraps, grounding mats and grounded work surfaces when servicing microprocessor devices. Transport boards and devices in static protected bags.

Ensure that there is sufﬁcient steam-process distilled water in the STATIM before activating the pump.

Safety Compliance

When a STATIM is serviced, the safety criteria as speciﬁed by applicable international safety standards and applicable national, state, provincial, and regional laws and regulations must be observed and maintained.

The following symbols appear in the margins of this book.

A potential hazard to the operator.

Asituation which may lead to a mechanical failure.

Identifying STAT

2000 Units

(Does not include ‘E’ models)

There are two main types of STATIM 2000 units, the G4 touchscreen version and Statim Classic with keypad. Each of these two versions have a North American speciﬁcation or “non S” unit, and the European speciﬁcation or “S” unit. In the Classic series, they are labeled respectively as “STATIM 2000” and “STATIM 2000S”.The G4 series models do not use the “S” designation in their names, but the G4 series does include S-class models for distribution in markets requiring these cycle types, and non S-class for the North American market.

There are many mechanical identiﬁers to differentiate between the set types, (e.g., pressure transducer for ‘S’ class, no pressure transducer for the non ‘S’ class). The details in the matrix further below will help you identify units based on their factory speciﬁcations.

Note that this section does not cover STATIM 2000E models. For more information on these, contact SciCan Technical Service.

Identifying Software Versions

To identify a unit’s software version, power it OFF and back ON again. During start up, a number is brieﬂy displayed in the upper right-hand corner of the LCD that indicates which software is installed (See Figure 1). This number is also printed on the label attached to the U14 microprocessor and the U8EEPROM device on the Controller Board (See Figure 2).

Note that units with Revision 3.x or 4.x controller boards WILL NOT display the software revision on the LCD display. These units will display “SELECT A CYCLE”.

The software version number is the character to the immediate right of the R as indicated by:

The Control Box (5) is a service tool that allows a technician to operate the unit while it is being serviced. There are two kinds of Control Boxes you may encounter: one uses toggle switches, the other uses a membrane keypad arrangement similar to the keypad on the unit.

When connecting the Control Box connectors to the Controller Board note the positions of Pin number 1 of the Control Box test connectors and Pin number 1 of the Controller Board headers.

The Control Box has a display (LCD) and a variety of control switches that allow the technician to:

1. Operate the unit independently of the keypad mechanism, to manually activate the pump, valve or compressor, or run cycles.

2. Make frequently used Controller Board measurements by providing a common output and rotary switch for signal selection during calibration. See the Calibration Instructions in chapters 4 and 5 of this service manual.

If only the display and button functions are being used, connect the LCD cable (6) to Controller Board connector P3, the keypad cable (7) to Controller Board connector P4 and power the STAT

ON.

If the override or measurement functions are being used, connect the test connector cable (8) to connector P1 of the Controller Board in addition to the other cables.

When using a toggle switch model of the Control Box, turn the switch to the ON position to activate the desired device. To turn the device OFF, turn the switch to the AUTO position. To select, start and / or stop a cycle, activate the appropriate push-button switch on top of the Control Box.

Calibration uses the Select out +, Select out - jacks and a setting on the Rotary Switch to set the calibration operation desired for Revision 3.x/4.x Controller Boards (for STATIM 2000 units only). See Calibration Procedure 1 or chapter 4 of this service manual.

When using a keypad model of the Control Box, the keypad switch must be held down to turn the desired device ON. Vref measurements use test leads, the Vref + and Vref - jacks and a voltmeter hooked up in series. Calibration uses the Select out + and Select out - jacks, test leads and a setting on the Rotary Switch to set the calibration operation desired for Rev. 3.x/4.x Controller Boards (for STATIM 2000 units only). The keypad of this Control Box provides the same features as a STATIM keypad. Note: The Control Box is for use with STATIM products ONLY.

Calibration Cassettes

The cassette of the STATIM unit is effectively a ﬁxed volume chamber that contains instruments during sterilization. Saturated steam at a speciﬁc temperature and pressure is introduced to produce the correct conditions for sterilization. The cassette is part of a sealed system designed to contain the pressurized steam. To calibrate the unit’s temperature and pressure (if appropriate) monitoring devices, a special calibration cassette must be used. The calibration cassette allows a technician to independently monitor the temperature and pressure inside the cassette, ensuring the unit is operating in accordance to its original speciﬁcations and to national/international standards.

Figure 4

Page 16

The relevant cassette types are detailed in the chart above, and the following important information should be noted before choosing the appropriate cassette to use.

• Non S unit cassettes require a 1.6mm (1/16”) temperature probe and cannot be used with

a 3.2mm (1/8”) temperature probe. (See meter details for probe diameter).

• S unit cassettes have temperature ﬁttings (one ﬁtted and one in the cassette accessories

supplied) that will allow the use of both 1.6mm (1/16”) and 3.2mm (1/8”) temperature probe. (See meter details for probe diameter).

• S unit cassettes are designed for both temperature and pressure reference meters and are

suitable for all models, S and Non S. If these cassettes are acquired, the non S, single port cassette is not required.

• The non S unit cassettes should not be used to calibrate S class units.

• Please note that when calibrating non-S units with an S unit cassette that the pressure

meter will not be required and the test port will require the pressure tube supplied with the cassette to be connected to the pressure ﬁtting to prevent steam leakage.

Reference Meters

Calibration reference meters are important for accurately setting the STATIM unit so that the correct sterilization conditions (temperature and pressure) occur in accordance with the original speciﬁcations of the unit and national/international standards.

When ordering any digital thermometer and temperature probe, ensure that the supplier is aware that the area where the most accuracy is required is between 130°C and 140°C.

Temperature meters and probes should always be calibrated as a matched pair.

Test equipment should be calibrated on a regular basis based on the manufacturer’s recommended calibration interval.

Calibration of reference equipment used with autoclaves should ALWAYS be to national or international standards by a certiﬁed calibration laboratory.

A number of meters are recommended by SciCan and are referenced as follows:

For non-S unit calibration

The following reference meters are recommended for use with 01-103087S and 01-103088S test cassettes:

• Omega HH81A single channel multifunction digital thermometer (www.omega.com)

• Omega TJ36-CASS-116G-6-SMP-M Temperature Probe (with SMP-M miniature male

connector).

Note: the above probe is 1.6mm (1/16”) diameter.

For S unit calibration

The following options are recommended for use with 01-106366S and 01-106367S test cassettes:

• A set of two independent meters, one pressure and one temperature.

• An integrated hand-held pressure and temperature calibrator.

Note: The thermocouple entry ﬁtting on the S class cassette will need to be changed from the

3.2mm (1/8”) diameter ﬁtting to the 1.6mm (1/16”) diameter ﬁtting if using the Omega meter.

The two independent meters have been included where the user may already have an Omega meter for non-S use who is upgrading to S class use, when only a pressure meter will be required.

They are also the lower cost options over the integrated device.

Setting Up your Reference Meters

With certain meter types, some sub-assembly procedures will need to be undertaken to connect the device to your Statim calibration cassette. All cassettes are supplied with the necessary accessories to enable you to convert your meter of choice from those recommended above, to the appropriate ﬁtting on the cassette.

01-103087S and 01-103088S cassettes (non S calibration) with Omega HH81A reference meter and TJ36-CASS-116G-6-SMP-M Temperature Probe.

No sub-assembly required.

To insert the temperature probe (thermocouple) into the compression ﬁttings, loosen the clamp nut attached to the cassette extension ﬁtting and insert the probe into the ﬁtting as far as it will go. A slight resistance will be felt as the probe passes through the seal. Tighten the clamp nut until a steam/air tight seal is achieved. DO NOT OVERTIGHTEN.

NOTE: The non S calibration cassette ﬁtting is NOT compatible with the Fluke and Heise 1/8” (3.175mm) temperature probes.

Figure 8. Temperature ﬁtting cut-away

If you have the SciCan supplied Omega HH81A type temperature reference meter with the 1/16” (1.6mm) temperature probe (normally used with the Non S-class type calibration cassette) then the compression ﬁtting attached to the S class cassette is correct and does NOT have to be removed.

If you have either the Fluke 51 type temperature reference meter, or Heise PTE1 type combined temperature and pressure reference meter then the 1/16” (1.6mm) compression ﬁtting (complete) will need to be removed from the extension piece attached to the cassette and replaced with the 1/8” (3.175mm) compression ﬁtting from the accessory kit, as both of these meters have 1/8” (3.175mm) thermocouple probes.

NOTE: PTFE tape should be used when assembling these parts to ensure a steam tight seal.

To insert the relevant temperature probe (thermocouple) into either of the appropriate compression ﬁttings, loosen the clamp nut and insert the probe into the ﬁtting as far as it will go. A slight resistance will be felt as the probe passes through the conical seal. Tighten the clamp nut until a steam/air tight seal is achieved. DO NOT OVERTIGHTEN.

2. Tools, Maintenance Schedules, Procedures and Testing

Check and adjust chamber thermocouple calibration as appropriate to board type.

Note: on ‘S’ class units, pressure transducer calibration using the pressure reference meter must be done during this phase. Software revision XXXXR4XX onwards requires this to be done at barometric pressure at the start of the cycle. Previous software variants require this to be done during the sterilization phase.

When set, and during the running cycle, check that the chamber temperature matches the reference meter and that actual and theoretical pressure are within 1 kPa. This is important for the efﬁcient balance of the

control and validation circuits. Failure to achieve this may result in unnecessary cycle failures.

Re-check steam generator thermocouple calibration as appropriate to board type.

• Note 1: steam generator calibration is not required for software revision numbers XXXXR4XX onwards.

• Note 2: if the initial steam generator calibration offset and ﬁnal steam generator caibration offset are > 8 hexadecimal values apart, the steam generator MAY be compromised and further investigation should be undertaken.

After completion of calibration, run a standard cycle to check temperature and pressure values.

Reinstall cover, and check all cycles are available.

Draining the Reservoir

If you have to service the reservoir, ship the STATIM, or move the unit more than a short distance, the reservoir will need to be drained to prevent potential water damage to the internal components (particularly the electronic and electrical components) of the unit.

Also, in some regions of the world, local or national guidelines recommend routine draining and cleaning of the reservoir to reduce the potential of the accumulation of contaminants in the feed water.

To drain the water from the reservoir, carefully move the STATIM to the edge of the work surface and proceed as follows (see Figure 19):

• The front leveler feet (1) should be approximately 12 mm (1/2 inch) from the edge so the unit remains securely seated on the work surface.

• Lift the front left corner of the STATIM upward and remove the drain tube (2) from the clip (3) located on the underside of the unit. Gently pull the tube out as far as possible so the free end can be positioned over a container when the unit is lowered back to the work surface.

• Remove the stopper (4) from the end of the drain tube and allow the water to drain from the reservoir.

• When water no longer drips from the drain tube, replace the stopper.

• Lift the front left corner of the STATIM upward and re-insert the tube into the clip on the

underside of the unit. Push the excess length of tubing back into the unit.

Keeping the STATIM cassette clean is good clinical practice and assists in the proper functioning of the unit. SciCan recommends that the interior surface be cleaned at least once a week. Cleaning the inside of your cassette is very important if you regularly sterilize lubricated instruments.

Use dish washing soap or a mild detergent that does not contain chlorine. Scrub the inside of the cassette with a cleaning pad designed for use with Teﬂon™ coated surfaces. After scouring, rinse thoroughly with water to remove all traces of the detergent.

Coating the entire inside surface with STAT-DRI drying agent induces water to form an even coat on the inside surface, without beading. The water in contact with the hot cassette surfaces also evaporates much more efﬁciently. Spotting is minimized and instruments dry much better.

Cleaning the Water Reservoir Filter (where ﬁtted)

This water reservoir ﬁlter should be cleaned at least once a week or when required. The ﬁlter can easily be removed and cleaned by placing the ﬁlter upside down under running water to wash away the particles until clean, and then placed back into the reservoir opening. Replacement water reservoir ﬁlters are available from you SciCan dealer.

Figure 21

Cleaning the Water Reservoir

Check the reservoir for dirt or particles. The reservoir may be cleaned by draining followed by cleaning and rinsing with steam process distilled water ONLY. Use of chemicals or cleaning agents is not recommended and could cause damage to the unit.

Changing the air ﬁlter and bacteria retentive ﬁlter (where ﬁtted)

Never re-use an old ﬁlter. Never run the unit without a clean ﬁlter in place.

After each sterilization cycle, the compressor forces air through the cassette to rid it of steam and to dry the instruments. The air is drawn into the compressor through one or two ﬁlters located at the back of the unit, depending upon which unit is being serviced.

Note: that some units may not have both or either ﬁlters ﬁtted depending on age, unit type,

compressor type, or if a compressor is ﬁtted.

Filters on the STATIM 2000/2000S/2000 G4

The STATIM 2000 type units draw air into the compressor (where ﬁtted) through a circular foam air ﬁlter located behind a cover plate on the rear of the compressor. This plate can be accessed from the rear of the unit with the cover still attached. The air is then directed to the steam generator and cassette, by the compressor, through a bacteria-retentive air ﬁlter (where ﬁtted) which is held in a bracket attached to the rear cover of the unit. If both ﬁlters are present, always change both ﬁlters at the same time.

Replacing the Cassette Seal

To ensure optimum performance of your STATIM cassette autoclave, change the cassette seal every 500 cycles or every six months, whichever comes ﬁrst. Replacement seals are available from SciCan (order number 01-100028S for STATIM 2000 and 01-101649S for STATIM 5000).

To change the cassette seal, follow these steps:

Place the cassette lid and the new seal on a clean work surface. Examine the position of the old seal in the cassette lid and arrange the new seal in the same orientation, next to the lid.

Remove the old seal by gently easing one corner of the seal out of the seal channel with a small screwdriver or similar device and then pull the remaining seal from the channel by hand. Ensure there are no sharp edges on the removal device that may damage the seal channel. Discard the old seal. Clean any residue out of the seal channel and ﬂush out the channel with distilled water.

Lubricate the new seal with the liquid seal lubricant provided. Do not use an excess amount of liquid, only use sufﬁcient liquid to lubricate the seal. Note: the seal will appear to be slightly larger in length and width

than the seal channel. This is intentional as the seal compresses into the channel when ﬁtted to ensure the correct pressure on the base of the cassette when closed.

Locate and align the steam inlet holes in the seal by inserting under the lip of the seal channel in the cassette lid and in line with the corresponding holes in the lid. The holes should be concentric to one another and the square tabs adjacent to the holes should be located evenly in the cut-outs in the cassette lid. Ensure seal sits ﬁrmly against the back of the channel.

Locate each corner of the seal under the lip of the seal channel in the cassette lid in the corresponding corners of the seal channel. At each corner, the two square tabs should be visible and located on the edges of the corner cut outs in the cassette lid.

Working from the centre position outwards on each side, locate the sides of the seal by inserting under the lip of the seal channel in the cassette lid and pushing the bottom section in until the seal sits ﬁrmly against the back of the channel. Ensure the seal is completely inserted. Running the thumb along the seal applying light pressure will allow you to feel any irregularities and evenly distribute the seal in the channel.

Note: During the ﬁrst cycle after changing the seal, steam may appear between the lid and the tray as the seal seats. If this persists, remove the cassette and check that the seal is correctly installed.

Be careful. The metal parts will be hot, and the cassette may contain hot steam.

Upgrading the ﬁrmware on STATIM G4 units

Upgrading the Interface Software can be done from a USB drive (similar to the process currently used for the Datalogger ﬁrmware update), a MicroSD card or a web site. The easiest and fastest method is to use a USB drive. To upgrade the ﬁrmware using a USB drive, proceed as follows:

1. Download new ﬁrmware. The ﬁrmware will be made available on MySciCan or emailed from SciCan upon request. It will be packed into a zip ﬁle (e.g. SL00R100.zip is the name of the current revision ﬁle, but the number will change with every revision) and must be extracted to a USB drive.

2. Check that you have the following ﬁles on the USB Drive:

•rmware.ini

•Firmware(Folder)

•SL00R100_4_100_CAA29608.sci

•cp.bat

•rmware.ini

Figure 26

3. With the unit powered OFF, insert the USB drive loaded with the ﬁrmware update.

4. Power ON the unit. The ﬁrmware will be updated automatically using the USB drive. This should take approximately 6 minutes. NOTE: The USB icon on the LCD touchscreen will ﬂash green while it is active. Do not remove the USB key while it is active.

5. When it is complete, the “Firmware.log” ﬁle on the USB drive will include the result of the upgrade (ﬁle name, upgrade OK, or upgrade failed, and for what reason).

6. Whether the upgrade is successful or unsuccessful, the “ﬁrmware.ini” ﬁle on the USB drive will be automatically deleted.

7. To retry or upgrade another unit, insert the USB drive into the PC’s USB port (NOTE there is currently no Mac version) and double-click the “cp.bat” ﬁle in the Firmware folder.Then remove the USB drive and repeat Steps 2 to 5.

Electrical safety testing

Dielectric Strength Test (Hi-Pot)

When mains electrical components are serviced or replaced and when the unit cover is removed and reinstalled following servicing, the dielectric strength of the electrical insulation between the mains and user-accessible conductive parts must be tested to ensure continued compliance of the unit with applicable international safety standards.

Exercise caution while performing this test. Hazardous voltages are present. Do not touch the unit, or allow the unit to touch any conductive surfaces during the test.

Perform the test using a dielectric strength (hi-pot) tester operated in accordance with the manufacturer’s written instructions using the following parameters:

STATIM Classic 2000 units W-Ramp: 2 Seconds W-Volt: 1500 V Dwell Time: 2 Seconds W-High: 3.5mA W-Low: 0.05mA Frequency: 60 HZ Continuity: OFF

STATIM G4 2000 units W-Ramp: 2 Seconds W-Volt: 1500 V Dwell Time: 2 Seconds W-High: 6.0mA W-Low: 0.05mA Frequency: 60 Hz Continuity: OFF

Connection Points: A. Unit chassis B. Live and neutral terminals of the mains plug connected together.

Page 44

For the unit being tested to pass, there must be no breakdown of the insulation or any ﬂashover.

Protective Bonding Impedance Test (Ground Continuity)

Applicable international safety standards require that the impedance between the protective conductor terminal of the power entry connector and any user-accessible conductive parts must not exceed 0.1 ohms. If any components of the protective earthing system are changed or any connections of that system are broken and remade, the impedance of the protective bonding must be tested and veriﬁed as being less than 0.1 ohms using test equipment and procedures in compliance with applicable International safety standards and national, state, provincial, and regional laws and regulations.

Diagnostics and Troubleshooting

When a STATIM unit fails to function correctly it is designed to ‘fail safe’ so that if sterilization conditions are not met, a message or cycle fault will appear on the display to inform you of the failure.

Depending on the age, type and controller variant of the machine, there are a number of things you can do to understand the problem. The following chapter contains guidance on what can be done on the various unit types.

Basic mechanical diagnostics

If the immediate cause of the problem is unknown and a cycle fault is unavailable, the following functional checks are recommended:

 •Inspecttheunitforexternaldamage.  •Removethecoverandinspecttheunitforinternaldamage.  •AttachacontrolboxandpowerONtheunit(ifpossible)andrunacycletoseeifthe

pump and compressor (if ﬁtted).

 •Performapumpowcheck.  •Checkcalibrationstatusoftheunit.

Using software as a diagnostic tool

Depending on the software in the problem unit there are a variety of things you can do to gather information to help with diagnosis. This varies from unit to unit and you will ﬁnd that the newer the unit, the more options are available.

For units with revision 2.x/5.x and 6.x controllers (no service menu)

For the above controller boards with version 2.xx and higher software it is possible to print out the last complete or incomplete cycle as a diagnostic tool. If the unit does not have a printer or if the printer was not connected when the fault occurred, a STATIM printer can still be used as a diagnostic tool, however the time and date printed on the report may not be valid.

To print the last cycle information, proceed as follows:

1. Turn the STATIM OFF and remove the cover.

2. Install a calibration jumper on controller board header W1 located to the left of the microprocessor. Connect a control box and printer to the controller board and enable the printer.

per button can be accessed by pressing any speciﬁc button repeatedly until the desired cycle is selected. This cycle is automatically the ﬁrst cycle to show on the display the next time the cycle button is pressed.

Note that units with Revision 6.x controller boards (rev 4.xx/5.xx software) DO NOT have a service menu, so the locking/unlocking procedure is different.

If you do not require some of the extra cycles, each button can have the redundant cycles ‘locked out’ to simplify cycle selection. Note that in ‘locked’ mode, each cycle button will only have

one cycle available. Single buttons cannot be locked, it must be all or none.

The cycles available on all ‘S’ class units mentioned above are as follows:

STATIM units monitor water quality using conductivity. The default settings are based on the minimum level required to detect water in the unit (except units ﬁtted with a ﬂoat – see below) and the maximum level required to protect the internal components from damage due to mineral deposits (e.g. Calcium) on the internal surfaces.

3. Troubleshooting Cycle Faults

This function allows the technician to adjust the water conductivity threshold. This may be required after a change of sensor and should be checked after a controller or software change.

Up to 2008, all units used the water sensor to detect both water quality and water level. In 2008, all units were upgraded with a ﬂoat in the chamber to detect level, which allowed the sensor just to monitor quality.

The default conductivity setup is as follows:

Note that these settings should NOT be changed to suit water used as damage MAY occur to the components of the STATim.

Units with sensor but WITHOUT ﬂoat

– LL.L (Lower value threshold / No water threshold. Values lower than this triggers

“Reﬁll reservoir empty waste bottle” error) = 0.3uS

– HH.H (Upper value threshold / Bad water quality threshold. Values higher than this

triggers “Water quality unacceptable” error) = 10.0uS

– G.GG Water conductivity circuit gain. Default value 1.00

Units with sensor and WITH ﬂoat

96-108639 Rev 2.0

– LL.L (Lower value threshold / No water threshold. Values lower than this triggers “Reﬁll

reservoir empty waste bottle” error) = FLOAT

– HH.H (Upper value threshold / Bad water quality threshold. Values higher than this

triggers “Water quality unacceptable” error) = 10.0uS

– G.GG Water conductivity circuit gain. Default value 1.00

On entering the Conductivity setup sub menu, the ﬁrst digit will be highlighted and can be changed as follows:

CD=xx.xuS/NNN/y.yppm L=LL.L H=HH.H G=G.GG

The ﬂashing value indicates the currently selected ﬁeld.

The values shown on the screen are as follows:

xx.x – Actual water conductivity in uS (micro-Siemens) as read by the unit software.

NNN - Water conductivity in ADC (Analog to Digital converter) counts (0…255)

y.y - Water quality in ppm (parts per million) as read by the unit software.

LL.L - Lower value threshold / No water threshold/Float status.

HH.H - High value threshold / Water quality threshold.

G.GG - Water conductivity circuit gain

Note that xx.x, NNN and y.y are for information only as measured by the unit software and can not be changed.

Screen display when in Water.Cnd Tmp. Comp sub menu.

Electrical conductivity can change with temperature and as a result provide a false reading possibly causing the unit to show a water quality/level fault when the water is in fact good. To overcome this, revision 7 STATIM units have water conductivity temperature compensation built in to the software to overcome this potential problem.

The default setting on all STATIM units is ON. To change this (NOT recommended) or to reset this condition should it change as a result of a software or controller change, follow these steps:

1. The UNWRAPPED or WRAPPED keys will switch the screen display to “ON” or “OFF” depending on the opening display.

There will be some cases of course where because of the unit type, a particular fault will not be appropriate (e.g. pressure faults on non S units where a pressure transducer is not ﬁtted) so establishing the following criteria before looking up a fault reference will assist in easier diagnosis.

Note also that the ‘probable cause(s)’ of any fault shown in the following chart are a GUIDE only. There may be multiple faults and the fault displayed may be either the ﬁrst problem the software has identiﬁed or as the result of a different but related issue. For example, a blown thermal fuse is only symptomatic of a boiler overheat, and not necessarily the cause of the failure, which may be through poor water delivery, so it would be useful to undertake an assessment of the unit as described earlier in this chapter under: “Basic mechanical diagnostics.”

Before referring to the following guide, establish the following where possible:

 •STATim type (2000/5000)  •Model type (‘S’ or non ‘S’)  •Controller board revision (2.xx/5.xx etc.)

– TIP: this is usually found on the bottom right hand corner of the controller

board except for revision 7 board where it may be located top right or bottom left depending on manufacturing revision. If in doubt, refer to Chapter 1 of this manual.

 •Software revision. (S2S2R415 for example, the R415 being the important part)

– TIP: this is usually found on the main microprocessor label, but the easiest

method is by powering up the unit. On all of the revisions refered to in this chart, this will appear on the top right hand corner of the LCD display for a few seconds after power up. If in doubt, refer to chapter 1 of this manual.

 •Cycle Fault number.

Note that there may be more than one of the same cycle fault which may be the same, but have different causes depending on the derivative of the unit, so when you have established these details, go to the CF number and use the ‘unit type’ and ‘software revision’ guide to establish if this particular CF is relevant (3) or not (6) as the case may be.

1. Reference Voltage Veriﬁcation / Adjustment

To verify / adjust the reference voltage:

1. Ensure the unit is OFF.

2. Connect the Control Box (1) to the Controller Board (2).

3. Connect the digital voltmeter (4) to the VREF terminals on the control box.

4. Set the voltmeter to read DC Volts with a resolution of 1mV.

5. Power the unit ON.

6. Adjust the VRH potentiometer (5) until VREF is 4.000 V ± 0.001.

7. Once VREF is adjusted, apply a drop of non-conducting lacquer or nail polish to the

adjustment screw of the potentiometer.

2. Steam generator thermocouple calibration

To calibrate the steam generator thermocouple:

1. Turn the control box SELECT knob to blr-chm. This signal is the difference between the

chamber and steam generator thermocouples.
