HANDLING PRECAUTIONS FOR PCB’S AND SOFTWARE

Chapter A - GENERAL & TECHNICAL DATA

5 HANDLING PRECAUTIONS FOR PCB’S AND

SOFTWARE CHIPS

5.1 Handling printed circuit boards

The circuit boards are well protected against static discharges when they are in the unit. However, some precautions are necessary when handling the boards since some internal nodes can easily be damaged by static electricity.This is true especially during low humidity conditions when there is evidently a potential risk of static discharges.

Keeping these few simple rules in mind when handling PCBs or software chips can make a big difference;

• Grounding wrist-straps are not necessarily required when handling the boards, as long as you first always touch a grounded exposed metal part in the unit before touching the PCB.

• Place the removed PCB immediately in an antistatic plastic bag. This protects it from later improper handling. Please note that PCB’s for warranty replacement must be returned to the factory properly packaged in antistatic plastic bags.

• Never place a removed PCB on a conductive surface or handle it to another person, without touching the surface or person first.

5.2 Handling software Flash-EPROM chips

To avoid static discharge problems the same rules that apply for PCB’s should be followed when handling software Flash-EPROM chips.

Software Flash-EPROM chips must be stored in their specific anti-static plastic tubes, protecting them also mechanically.

Since the software chip used is a PLCC-type chip, it must be removed only with a proper extracting tool (see the spare part manual for details). Using any other tool for removal can seriously damage the socket on the MCB.

Please refer to 5.1 “How to replace/upgrade the software” on page G-20 for details how to replace the software.

1 GENERAL ABOUT THE SERVICE MODE

The service mode is intended to assist the technician in the service and setup of the unit:

• display of all internal signals from sensors and switches

• display of internal voltages and other variables

• display of output and control signals

• adjustment of unit’s parameters

• preset of all the parameters to the factory default

The service mode is entered using a special key sequence. The entry has been made difficult on purpose to prevent accidental entry. The numeric display and the chair control keys change meaning in the service mode. The rest of the keys and the unit work normally.

NOTE The user display is replaced with service mode information, and no error or

help codes are displayed in the service mode.

NOTE Even if listed in this documentation, some service modes are reserved for

future use and might not yet be implemented in the current software version.

1.3 Navigating among the various service modes

The service modes are numbered with consecutive numbers. To move to the required service mode, use the chair up and down keys (“C” or “D”) on the control panel. All the patient chair control keys are now used for controlling the service mode and do not control the chair.

Press to move up in the list Press to move down in the list

The current service mode number (symbol “n” followed by the current service mode number) is shown on the display when moving around in the list.

Due to the small display, there are not enough digits to show simultaneously the service mode number and its contents. Therefore the service mode number disappears after 1 second, after which the current service mode setting or value is displayed.

Checking the current service mode number

When the service mode setting is shown on the display, pressing briefly either of the moving keys (“C” or “D”) brings momentarily the number of the current service mode to the display. The unit does not move to the next (or previous) service mode.

1.4 Changing an adjustable setting in the service mode

Some of the service mode numbers display a decimal point after the symbol “n”. These modes have settings that can be changed. To change a setting do as follows:

Press and hold until LED lights

to enter the SET mode

a) Move to the desired service mode as described in 1.3 “Navigating among the various service

modes”.

b) Enter the SET-mode by pressing and holding the “S”-key until the yellow indicator light turns

on (1 or 5 seconds, depending on the service mode). c) Decrease the setting with the “A”-key, or increase it with the “B”-key. d) Exit the SET-mode by briefly pressing the S-key (the indicator light turns off). The SET-mode

is exited automatically if you scroll to a different service mode using the “C” and “D” keys.

However, any changes made to the previous service mode are stored.

Decrease the setting

service mode by using the program key. All altered settings, even if they have

an immediate effect, are lost if the power is turned off before pressing the pro-

gram key.

This behaviour can, however, be used as a “master undo”, if you for some rea-

son want to return to the previous settings. The factory presets (mode 16) are

stored immediately and cannot be un-done.

Chapter C - SERVICE MODE

n 1 Show software version on MCB (n.nn.n version)

Shows the currently installed software version on the MCB. Shows normally version number (“3.02.5” ie. 3 = Major version, 02 = minor version and 5 = fix version). When in Set-mode, shows “234.b” where 234 is build version and b can be d, b or r where d for development, b for beta and r for release.

The software version is also briefly displayed whenever the unit is turned on. There is normally also a label on top of the software chip containing the same information.

The unit’s behaviour, features and functions depend completely on the installed software. Always use the latest software available, especially if you notice that some features are missing described in any available documentation.

Some new instruments or retrofittable extensions might require a MCU software upgrades. In this case the unit will display automatically respective help or error codes (HE9, HE14, E16, E19.n, E32.n, E47.n, E52, E62).

The foot-control and the IMUX also both contain microprocessors. Their software is “embedded” inside their respective CPU’s and cannot therefore be replaced. Since the “main brain” is the MCB and its microprocessor, there is rarely ever a need for this. However, you can check their software versions by using service modes n19 and n60 (respectively).

n 2 Show internal unregulated operating voltage (nn.n volt)

SERVICE MODE DETAILED DESCRIPTION

This voltage reflects mains voltage magnitude variations. The nominal value is +33VDC and is allowed to vary ± 15% (28...38V) without affecting the normal operation of the unit.

If one of the MCB electronics fuses (F9 or F10) is blown, the display will only be half of normal (Ý16.5VDC ± 15%). If the internal voltage is too low or too high, the unit will show respective error codes (E9 or E10). If the internal voltage rises above 44VDC (a heavy mains surge, too high mains voltage, wrong voltage jumper position or wrong transformer primary wiring), an internal protection circuitry will blow fuses F9 and F10, protecting the unit electronics from failure.

n 3 Show output current of IPS (n.nn ampere)

This is the output current of the instrument power supply (IPS) located on the MCB. This microprocessor controlled power supply feeds power to micromotors, light-curing bulbs and scaler units. This built-in ampere meter is intended for checking the current consumption of the selected instrument. If the current is continuously zero it indicates an open-circuit somewhere between the MCB and the instrument. This mode is also good for checking the no-load current of micromotors, that is a direct indication of the motor condition.

n 4 Show output voltage of IPS (n.n volt)

This is the output voltage of the instrument power supply (IPS) located on the MCB. This microprocessor controlled power supply feeds all micromotors, light-curing bulbs and scaler units with appropriate voltages. The voltage on the display is measured directly at the IPS output on the MCB, therefore the voltage shown is normally somewhat higher than the instrument receives. However, the voltage drop in the cabling is compensated for so that instruments always receive a proper voltage.

SERVICE MODE DETAILED DESCRIPTION

n 5 Show scaler electronics ID-code (n id-code) and

connection point of the scaler electronics (--n-) or (---n)

The (optionally) installed scaler electronics module is identified by a jumper wire on its connector that plugs to the MCB. It is important for the MCB to know the type of scaler electronics installed. This service mode allows you to check what type of scaler electronics is installed and that the identification works properly. It is also possible to check if the scaler electronics is installed on the MCB or at the IMUX.

The location of the scaler electronics is indicated on the display by pressing the S-key with delay. If the display (--n-) is shown then the electronics is connected to IMUX or (---n) then the electronics is connected to MCB.

0 No scaler electronics module installed 1 AMDENT scaler module installed 2 EMS scaler module installed 3 SATELEC scaler module installed 6 Newtron scaler module installed 4-5, 7 reserved

n 6 Show service door switch signal (n door status)

This is the signal from the microswitch that indicates the door status (1 = door open, 0 = door closed). An open circuit, broken wire or loose connector is interpreted as the door would be continuously open. During this condition the chair cannot be run, except for in the service mode when the control system temporarily ignores this signal.

Chapter C - SERVICE MODE

n 7 Show mains frequency (nn.n Hz)

There is no other use for this service mode than checking the condition of a part of the MCB electronics. If everything is OK the display should be stable within ±2 digits. Severe mains voltage transients can up-set the display temporarily, and would also cause the OP-light to flicker. If this display is stable but the OP-light flickers occasionally, it’s probably caused by a bad bulb socket.

n 8 Show (optional) assistant syringe hose ID (n id-code)

If no hose is connected (or if the assistant syringe option is not installed) the display should show a dash “-”. If any other instrument than a syringe is connected then the display should show 0 (zero). If a valid syringe (hose) is connected then the display shows the syringe hose ID-code (e.g. 20).

n 9 Show (optional) assistant syringe hose sense signal (nnn

signal)

Same as above but this is the direct signal from the assistant syringe hose identification circuitry. The display range is 0-255. 255 indicated an open circuit, 0 indicated a short, any other values represent the signal. The display should be fully stable within one digit.

n 10 Show MCB heatsink temperature (nn °Celsius or

°Fahrenheit)

Technical Manual

The temperature is measured inside the black aluminum block on the MCB. During normal circumstances the temperature should stay below 55°C. The temperature can rise above this level if the fixing screws (that attach the heatsink to the aluminum box) are missing. To protect against overheating the CPU turns off those loads that contribute to the power dissipation (OP-light and IPS) if the temperature rises above 60°C, The error E15 is then also displayed.

Chapter C - SERVICE MODE

n.11 Enable (optional) water heater (n mode = 0, 1)

The purpose of this mode is to guarantee that the (optional) water heater is not powered up without water. When the unit is shipped from the factory the mode is set to 0 (heater off). During the installation (but after the water and drain is connected) this mode should be set to 1 (if there is a water heater attached). When the mode is set to 1, water will be flown from the glass fill for 10 seconds.

n.12 Set main air valve operation (n mode = 0, A, 1)

The main (incoming) air valve is controlled by the CPU. The operation is automatic, in other words, the valve opens only when necessary. This behaviour can be temporarily bypassed in this service mode. Set the mode to 0 (zero) to keep the valve continuously closed, set to “A” to go back to automatic or set to 1 to force the valve to open. Please note that even if this mode is programmed to 0 or 1, it always automatically defaults to “A” after turning off the power to the unit.

n.13 Set main water valve operation (n mode = 0, A, 1)

The main (incoming) water valve is controlled by the CPU. The operation is automatic, in other words, the valve opens only when necessary. This behaviour can be temporarily bypassed in this service mode. Set the mode to 0 (zero) to keep the valve continuously closed, set to “A” to go back to automatic or set to 1 to force the valve to open. Please note that even if this mode is programmed to 0 or 1, it always automatically defaults to “A” after turning off the power to the unit.

SERVICE MODE DETAILED DESCRIPTION

n.14 Disable automatic functions in S-position (n mode = 0, 1, 2,

)

This service mode can be used to disable automatic cuspidor flush and cup fill functions when using the chair S-position. 0 = no automatic functions, 1 = cuspidor flush only, 2 = cup fill only, 3 = both.The factory default is 3 (all functions).

n.15 Disable error messages (n mode = 0, 1, 2)

This service mode can be used to disable the error message display system. The only use for this mode is during exhibitions or in showrooms where a full installation is not possible (no water and/or water pressure), and because of this error messages would be continuously displayed. Set the mode to 0 to disable the error messages, or to 1 to enable the error messages (factory default), or to 2 to disable the error messages related to the console arm. The unit shows shortly HE12 when turning the power on (remainder of that the error messages are disabled).

SERVICE MODE DETAILED DESCRIPTION

n.16 Enable factory preset mode (- or S U)

This service mode is used to set the unit to a predefined state only using few keystrokes. This feature is mainly used at the factory, that is why it is called a “factory preset”. All user programmable settings and parameters, as well as the most important service mode settings can be set to a “normal” state. Then the unit can be immediately operated without having first to do any adjustments or programming. This is useful also on the field if a showroom unit is installed later for clinical use.

Upon entry this service mode shows a dash (-) in the display. Press the S-key for 2 seconds (prevents accidental entry) so that the yellow LED lights in the key. The display now shows S U.

Performing user mode presets

Press the B-key briefly (“below” the U symbol in the display) to perform the user mode presets (the display shows FP.U during the process). Pressing the B-key sets the factory presets for the user-controlled settings, which are: period of glass filling, period of bowl rinsing, period of door open/nurse call, settings of the dentists (chair positions: backrest, height, light), timer settings, intensity of the operating light and instrument settings (spray, power reduction, chip blow etc.). After performing the user mode presets the text “turn off” will flash on the display. Now turn off the unit.

Chapter C - SERVICE MODE

Performing service mode presets

Press the A-key briefly (“below” the S symbol in the display) to perform the service mode presets (the display shows FP.S during the process). Pressing the A-key sets the factory presets for all the service mode settings. After performing the service mode presets the text “turn off” will flash on the display. Now turn off the unit.

n.17 Select display units for pressures and temperature (n

mode = 1

The unit can show pressures (in the service mode) in either bar, kPa or PSI. Select mode 1 to show the pressure in bar (factory default), 2 to show the pressures in kPa (kiloPascal), or 3 to show the pressures in PSI (pounds per square inch). If mode 3 is selected additionally temperature displays (ex. service mode 10) are shown in °Fahrenheit instead of °Celsius. Select mode 4 to show the pressure in PSI and temperature in °Celsius.

2.2 Instrument MUX related service modes

n 19 Show software version of IMUX CPU (n.nn software version)

This is the software version of the embedded software inside the IMUX CPU EEPROM. This software can be updated on the field.

n 20 Show instrument holder & AUX-input signals (¦ ¦¦¦¦¦

signal)

This service mode is convenient for checking the proper operation of the doriot arm sensors (on the IMUX PCB). The 5 rightmost segments represent the 5 instrument positions, from right to left respectively. A short vertical bar indicated that the instrument is in the holder, a long vertical bar that it is taken out from the holder. The leftmost vertical bar shows the signal at the AUX input terminal on the IMUX PCB (6th instrument place).

n 21 Show active instrument hose ID-code (---- or nn ID-code)

This mode is convenient for checking the instrument hose ID-code and the related electronics on the IMUX PCB. The code range is 1 to 26.

The display shows four dashes (----) if no instrument is selected. Activate a properly attached instrument hose (in this same location) to display the ID-code. The code displayed should be the same as indicated by the last digit(s) on the label on the quick connector.

n 22 Show active instrument hose identification signal (nnn

signal)

This service mode is similar to the one above. This mode shows the actual signal measured from the identification pins on the instrument hose quick connector. The signal range is 0 to

510. The display should show 223 to 228 when no instrument is selected (the electronics meas-

ures a local reference signal). If the signal is outside this range then there is an error on the IMUX PCB. Check for any water leakage.

Activate a properly attached instrument hose (in this same location) to display the identification signal.

n 23 Show active instrument switch/sensor signal (---- or nnn

signal)

This service mode shows the instrument (optional) switch or sensor input signal. The display shows four dashes (----) if no instrument is selected. The display range is 0 to 255.

Activate a properly attached instrument hose (in this same location) to display the ID-code.

n 24 Show console syringe location hose ID-code (nn ID-code)

This service mode shows the hose ID-code for the hose connected to the syringe location. The display shows zero (0) if no hose is attached, otherwise the hose ID-code is displayed continuously.

SERVICE MODE DETAILED DESCRIPTION

n 25 Show console syringe location hose identification signal

(nnn signal)

This service mode shows is similar to the one above. This mode shows the actual signal measured from the identification pins on the connected hose. The display range is 0 to 255. A continuous 255 indicates an open circuit, a continuous 0 a short. The signal should be stable within ± 1 digit.

n 26 Show console syringe switch signal (nnn signal)

This service mode shows the (optional) switch signal from the syringe. At this moment no syringes use this signal, therefore 255 is always shown.

n 27 Show IMUX on/off valve signals (¦¦¦¦¦¦ signal)

This service mode shows the actual driver output signals controlling the on/off type electromagnetic valves inside the IMUX. The five first vertical segments (counting from right) represent the four instrument and one syringe select valves, respectively.

The sixth (leftmost) vertical bar shows the (optional) steripump control valve / extra water valve signal.

A short vertical bar indicates that the valve is off and that the valve is connected properly (not open circuited). A long vertical bar indicates that either the valve is on or that the valve is open circuited.

Chapter C - SERVICE MODE

When the SET-mode is entered, IMUX IC16 output signal feedback inputs are displayed: 1st vertical segment (counting from right): Syringe water control

2nd: Instrument 4 membrane control valve 3rd: Instrument 3 membrane control valve 4th: Instrument 2 membrane control valve 5th: Instrument 1 membrane control valve 6th: steripump control valve / extra water valve 7th: Syringe fibre light electronics 8th: Syringe heater

n 28 Show IMUX other output signals (¦¦¦¦¦¦ signal)

This service mode is similar to the one above. This mode shows the other outputs driver statuses controlling the relays and other outputs. This service mode is mainly intended for factory use.

n 29 Show air / water pressure difference

This service mode shows the measured pressure difference between the internal continuous air pressure and the regulated spray water fed to the instruments. This pressure difference should always be greater than 1 bar (100kPa) to guarantee proper operation.

n 30 Show active instrument drive/cooling air pressure

(n.nn bar; nnn kPa; nn.n PSI pressure)

Technical Manual

This service mode shows the signal from the drive/cooling air line pressure sensor. The display is either in bar, kPa or PSI, depending of the setting in the service mode n.17. The pressure is measured inside the IMUX just after the proportional valve controlling this line. Therefore this pressure display is (under normal flow conditions) always higher than the pressure measured at the instrument end of the hose.

Chapter C - SERVICE MODE

n 31 Select the service mode navigation type (0, 1, 2, 3)

In this service mode the service mode navigation type can be selected. 0 = Normal navigation. The service mode number is changed in steps of one when using the

chair up and down keys (“C” or “D”) on the control panel. 1 = factory use 2 = Accelerated navigation. The service mode number is changed in steps of 5 when the chair up or down is pressed and held down. 3 = factory use

The factory default is 2.

n 32 Show active instrument spray air pressure

(n.nn bar; nnn kPa; nn.n PSI pressure)

This service mode shows the signal from the spray/chip air line pressure sensor. The display is either in bar, kPa or PSI, depending of the setting in the service mode n.17. The pressure is measured inside the IMUX just after the proportional valve controlling this line. Therefore the pressure measured (under normal flow conditions) is always higher than this same pressure measured at the instrument end of the hose.

n.33 Factory test

SERVICE MODE DETAILED DESCRIPTION

Reserved for factory use.

n 34 Show active instrument spray water pressure

(n.nn bar; nnn kPa; nn.n PSI pressure)

This service mode shows the signal from the spray water line pressure sensor. The display is either in bar, kPa or PSI, depending of the setting in the service mode n.17. The pressure is measured inside the IMUX just after the proportional valve controlling this line. Therefore the pressure measured (under normal flow conditions) is always higher than this same pressure measured at the instrument end of the hose. Because of the construction of the water channel the pressure drops very slowly towards 0 (zero).

n 35 Factory test

Reserved for factory use.

n.36 Set mode of IMUX membrane operation (n mode = 0, 1)

This service mode selects the mode of operation of the IMUX instrument select membrane control valves. The unit software must be upgraded if mode 1 is not available and needs to be used. This feature was added to the software version 1.23 (and later).

Mode 1 is recommended to be selected in new units, since in this mode all instrument select membranes in the IMUX will stay normally closed (pressurized). The benefit is that there is no risk of water leakage or occasional water drops from the instruments. In this mode the integral spray water back pressure valves are only needed when the unit is powered off. This continuous activation of the (4) valves causes some additional heat dissipation in the IMUX (about 8W). Early IMUX assemblies have not been tested with this higher power dissipation and could give problems (due to some tight tolerances) with sticking doriot arm pins. Assuming that the pins are replaced with thinner ones, then the mode 1 can be used in all IMUXes.

Mode 0 is recommended to be selected in older units with IMUX assemblies manufactured earlier than Jan. -96. In this mode all instrument select membranes stays whenever possible open (not pressurized). Then prevention of water dropping from instruments (when idle) is fully dependent of the operation of the integral back pressure valves.

HELP & ERROR MESSAGES

1 HELP MESSAGES

1.1 General about help messages

The help messages are intended to assist the user in special situations. A help message usually indicates a user error rather than a system error or malfunction. The help messages mainly cover the following areas:

• violations against built in security functions

• warnings about amalgam collectors that needs to be emptied

• controls or keys with no response in certain situations

• erroneously attached instruments

• notifying the user of abnormal conditions that cannot be categorized as errors.

The help messages appear on the display as capital letters “HE” followed by a number. The message stays on the display only as long as the reason for it continues. The unit is otherwise fully functional, except for the reported problem. Only one help message is shown at a time.

After the unit has been updated with the latest version of the MCB software it may report a help message that is not listed in this manual. In this case, please request a new revision of the manual. The following table is a list of currently available help messages and their reasons.

Chapter D - HELP & ERROR MESSAGES

2 ERROR MESSAGES

2.1 General about error messages

The error messages are intended to assist the technician in situations where the control system detects a condition that could be a possible fault. An error message usually indicates a system error or malfunction rather than a user error. The error messages cover the following areas:

• insufficient pressures to control the instruments or other pneumatic problems

• failed (open or short circuited) cables and/or valves

• printed circuit boards not functioning properly

• failed bulbs and/or fuses

• power supply failures or problems

• non-compatible printed circuit boards or software versions

• sensor and switch failures

• other miscellaneous errors.

ERROR MESSAGES

The error messages appear on the display as a capital letter “E” followed by a number (“n.n”). The number (left side of decimal point or if no decimal at all) indicates the type of error. Some error messages also have a decimal part (number on the right side of decimal point). This decimal part determines in more detail the reason for the error.

The error message stays on the display only as long as the error exists. In the case of several simultaneous errors, the display shows them one at a time, in ascending number order. The unit is otherwise fully functional, except for the reported error(s). Error messages are not stored internally for later retrieval.

After the unit has been updated with the latest version of the MCB software it may report an error message that is not listed in this manual. In this case, please request a new revision of the manual. The table on the following pages is a list of currently available error messages and their meanings. For a detailed description of the error messages please refer to the indicated pages.

2.2 Disabling/enabling error messages

The error reporting system can be disabled (service mode 15). This is useful in exhibitions or showrooms when a complete installation cannot be made (missing vacuum, water or air supply). In these cases the errors should be disabled so that the unit does not unnecessarily show error messages on the display.

The unit briefly flashes an “HE 12” message on the display at power-on, to remind that the error message system is disabled. Please refer to service mode “n.15 Disable error messages (n mode = 0, 1, 2)” on page C-20 for details how to enable/disable the error message system.

DETAILED DESCRIPTION OF ERROR MESSAGES

3 DETAILED DESCRIPTION OF ERROR MESSAGES

3.1 General error messages

E 1.nn Output short circuit on MCB

All valve and extra outputs on the MCB are short-circuit protected. Additionally, the MCB CPU system is able to read the signal levels on the output pins. Therefore the following detailed information can be presented about the possible short circuit.

E 1.01 Main water valve short circuit E 1.02 Main air valve short circuit E 1.03 Bowl rinse valve short circuit E 1.04 Cup filling valve short circuit E 1.05 Water flush valve short circuit E 1.06 Separator pulse valve short circuit (only with Microvac’s) E 1.07 Ejector valve short circuit (only if defined as an option) E 1.08 Extra out 1 short circuit (High volume membrane valve, reserved) E 1.09 Extra out 2 short circuit (Saliva suction membrane valve, reserved) E 1.10 Extra out 3 short circuit (Reserved) E 1.11 Separator start signal/Microvac’s start valve short circuit E 1.12 Assistant syringe water valve short circuit E 1.13 Separator alarm reset signal short circuit E 1.14 PLANET output (ELMP) short circuit

These errors can only be detected when the circuit is active. Disconnect the valve or output indicated and check if the error disappears. Otherwise the

problem must be in the cable, or as the last possibility, on the MCB. If the error does not disappear even if the valve cable at connector P16 on the MCB is disconnected, then the MCB must be replaced. Advanced

: Replace both IC37 and IC36 on the MCB.

E 2.nn Main Control PCB output open circuit warning

The following list indicates which output is causing the trouble; E 2.01 Incoming water valve open circuit

E 2.02 Incoming air valve open circuit E 2.03 Bowl rinse valve open circuit E 2.04 Cup filling valve open circuit E 2.05 reserved E 2.06 Separator pulse valve open circuit (only with Microvac’s) E 2.07 reserved E 2.08 reserved E 2.09 reserved E 2.10 reserved E 2.11 Separator start signal open circuit / Microvac valve open circuit E 2.12 Assistant syringe water valve open circuit E 2.13 Separator alarm reset signal open circuit E 2.14 reserved

These errors can be detected when the circuit is dead. Disconnect the connectors at the end of the indicated bad valve (load). Measure with an ohm-

meter that the valve resistance is in the range 50-300Ω. Disconnect the valve connector P16 on the MCB and check the condition on the indicated valve cable wires. Check that both the disconnected wires are OK all the way to P16.

DETAILED DESCRIPTION OF ERROR MESSAGES

E 3.n General pressure problem

E 3.1 Incoming air pressure compared to the water pressure is too low The internal air pressure (after the internal pre-regulator) must always be 100kPa higher than

the internal water pressure (after the internal pre-regulator). Otherwise the membranes in the IMUX doesn’t close properly. Normally this never causes a problem, except for the cases when the system compressor is accidentally turned off during the use of the unit. Check that the incoming pressure is according to specifications. Also measure (and readjust if necessary) the internal pressures of the unit. Use either an external manometer attached to the syringe, or use the internal service mode system for the check. Check also the condition of the water and air filters. Look for any kinks in the air tube going to the IMUX.

E 3.2 reserved E 3.3 reserved E 3.4 Internal air pressure (after pressure regulator) is too low E 3.5 Internal air pressure (after pressure regulator) is too high

Check the condition of the input pressures to the unit. Is an external valve or compressor accidentally closed? Check the water and air filter. Check (and readjust if needed) the internal pressures.

E 4.n Short circuit in the cable from the MCB to the control panel/ suction holder in branch n

Chapter D - HELP & ERROR MESSAGES

E 4.1 Short circuit in the cable from the MCB to the control panel/suction holder

in branch 1

E 4.2 Short circuit in the cable from the MCB to the control panel/suction holder

in branch 2

The problem must be in the cable, or as the last possibility on the control panel PCB or suction holder PCB or MCB. Localize the short circuit in the cable, and repair the cable or replace it. If the error does not disappear, then the control panel PCB or suction holder PCB or MCB must be replaced.

E 5, 6 reserved

3.2 Power Supply related error messages

E 7 IPS voltage failure on MCB (IPS = Instrument Power Supply)

The IPS output voltage is too high. Disconnect the P3 (cable to the IMUX) on the MCB. If the error is still there, then the MCB IPS power supply is faulty. Advanced Q6, Q9 and Q7 on the MCB.

If the MCB is OK; check the condition of the IMUX (8-wire) cable by disconnecting it both at the IMUX and MCB. Measure all wires for shorts between each others as well as the chassis. Replace the cable or the IMUX.

Chapter D - HELP & ERROR MESSAGES

E 9 Internal operating voltage too low

Check first the mains voltage at the input terminals (P25) on the MCB. If the error only occurs when running the patient chair then check that the mains impedance is not too high so that the incoming mains voltage does not drop under the minimum allowed. The following voltage variations are allowed to guarantee normal operation;

• 230 volt setting (Europe) mains can be from 187VAC to 265VAC

• 115 volt setting (USA) mains can be from 98VAC to 132VAC

• 100 volt setting (Japan) mains can be from 80VAC to 110VAC If the incoming mains voltage is at any instance outside the indicated range then an external

voltage stabilizer must be considered. Check that both fuses F9 and F10 on the MCB are OK. If the error still appears, especially in the lower range of the mains voltage, then the MCB must be replaced. Advanced around the voltage measurement filter.

E 10 Internal operating voltage too high

Check first the mains voltage at the input terminals (P25) on the MCB. Do the same checks as above. Make sure that the voltage selector jumper is set properly.

E 11.n Secondary fuse blown on MCB

DETAILED DESCRIPTION OF ERROR MESSAGES

: Check the condition of D9, D11, D14, D15, and components

The conditions of the secondary fuses are indicated also by green LEDs at each fuse holder position. Please look at the inner side of the PCB edge. If a green LED is dark, then the respective fuse at that position is blown. The following list gives more details about the blown fuse. Please remember to replace the fuse with the same type and rating indicated, to guarantee safety of the equipment;

E 11.1 OP-light fuse (F5) and/or Water heater fuse (F7) is blown on the MCB E 11.2 Separator fuse (F6) and/or the Syringe heater fuse (F8) is blown on the MCB E 11.3 Either of the +24V electronics fuses (F9 or F10) is blown on the MCB

Always turn off the power during fuse replacement. If a fuse blows immediately again, try to disconnect the respective load (OP-light, Water heater, Separator or Syringe) to check whether the load itself is causing the problem.

E 12 reserved

E 13 Mains frequency outside acceptable range

The mains frequency is measured by the MCB and is needed to synchronize both patient chair AC motors and the OP-light operation. If the mains frequency is OK and the error still repeats (with possible OP-light flickering) then the MCB must be replaced. Advanced R167, C82, R159, IC8-5 and IC8-6.

E 14 IPS temperature measurement sensor error

: Check

The voltage from the temperature sensor is outside the normal operating range. Check visually the board around the heatsink for any damage. Replace the MCB.

E 15 IPS heatsink is running too hot on MCB

All power semiconductors on the MCB are attached to the same heatsink. For proper cooling, this heatsink must be attached properly to the left side to the electronics control box. Check that the two screws are in place and tight. When the heatsink temperature reaches the maximum allowed (Ý60 °C) this error is generated. The CPU on the MCB first turns off the OP-light and secondly the output power to the dental instruments, if the temperature still rises a few degrees. This safety feature makes it impossible to overheat the MCB heatsink.

E 21, 22 reserved

3.4 Instrument related error messages

E 23 Polymerization light bulb is blown or not properly attached to the socket

The MCB monitors the current flowing from the IPS to the curing light bulb. If the current is abnormally small then this error is generated. Check the bulb and the condition of the bulb socket. Some lights (LYSTA) have in series with the bulb connected a temperature fuse, that might have triggered (overheating). Check also the condition of the quick-connector pins. If it still does not come on, check that the micromotor or the scaler operates to make sure that the cables in the arm between the MCB and IMUX are OK.

3.5 Instrument multiplexer related error messages

E 28 Error in hose identification system in IMUX

The hose ID measurement signal is out of bounds. If this error only occurs with one instrument; check the condition or corrosion of the quick connector pins. Replace the hose. Check visually the IMUX for any water leakage or corrosion on the PCB. Replace the IMUX if necessary.

E 28.1 Reference resistor signal out of bounds when unit is switched on E 28.2 Active instrument signal out of bounds E 28.3 Syringe signal out of bounds E 28.4 Reference resistor signal out of bounds when instrument is activated E28.5 Syrine signal changes during use (blinking)

E 29 Voltage error in the fibre-light power supply in the IMUX

The fibre-light voltage regulator is not able to regulate the voltage to the fibre-light bulbs. During this error the instruments containing a fibre-light (turbines, micromotors and syringes) are not activated, to save the bulb from destruction. If this problem only occurs with one instrument then try first to replace the hose for this before replacing the whole IMUX.

E 30, 31 reserved

E 32.n Error in serial communication between MCB and IMUX

The communication between the MCB and IMUX is serial to reduce the number of wires to a minimum between these two. The MCB generates this error if there is any reason why it cannot communicate with the IMUX. Here are the reasons and remedies;

E 32.1 IMUX is not responding. IMUX cable disconnected or failure in cable or IMUX. Check the two LEDs on the IMUX. If both are dark, check the cable at both ends. Disconnect

the cable from both ends and measure all wires for shorts or opens. The green LED indicates (on IMUX) that the IMUX gets power from MCB. The yellow LED (when blinking) shows that the IMUX CPU is running and communicating with the MCB. Try with an external cable outside the arm, or try to connect temporarily another IMUX externally to check what is causing the problem.

E 32.2 IMUX software is not compatible (IMUX is of new type), with the MCB software. A new IMUX has just recently been installed that has some new features that the MCB soft-

ware cannot use. Please upgrade the MCB software. After the upgrade the MCB is still compatible with older versions of the IMUX as well.

E 32.3 IMUX data error (cable short circuit) (data low all the time) Check the pin 6 in P3 on the MCB that it is not shorted to the chassis. Try with another IMUX.

This line is short circuit proof and cannot be harmed even if shorted to ground.

E 32.4 IMUX communication error (checksum or parity) (1 sec timeout) The communication between the MCB and IMUX seems to work most of the time, but there

can be an intermittent contact problem in the IMUX cable. Check the connectors and the pins. E 32.5 Wrong IMUX type or wrong unit type, see service mode 100 and 103.

DETAILED DESCRIPTION OF ERROR MESSAGES

E 33.n IMUX output short circuit

All valve outputs on the IMUX are short-circuit protected and can withstand short circuits. Additionally, the IMUX CPU is able to read the level on the output pins. Therefore the following detailed information can be presented about possible short circuits.

E 33.1 Syringe select valve (lifetimes) short circuit E 33.2 Instrument 1 select valve short circuit E 33.3 Instrument 2 select valve short circuit E 33.4 Instrument 3 select valve short circuit E 33.5 Instrument 4 select valve short circuit E 33.6 reserved E 33.7 Drive/Cooling air valve short circuit E 33.8 Air coolant valve short circuit E 33.9 Water coolant valve short circuit

These errors can only be detected when the circuit is active. Disconnect the valve indicated and check if the error disappears. Otherwise the problem must

be in the valve or its cable, or as the last possibility, on the IMUX. If the error does not disappear even if the valve connector is disconnected, then the IMUX must be replaced.

E 34.n IMUX output open circuit

Chapter D - HELP & ERROR MESSAGES

The following list indicates which output is causing the trouble; E 34.1 Syringe select valve open circuit

E 34.2 Instrument 1 select valve open circuit E 34.3 Instrument 2 select valve open circuit E 34.4 Instrument 3 select valve open circuit E 34.5 Instrument 4 select valve open circuit E 34.6 reserved E 34.7 Drive/Cooling air valve open circuit E 34.8 Air coolant valve circuit E 34.9 Water coolant valve circuit

These errors can be detected when the circuit is dead. Disconnect the connector of the indicated bad valve (load) from the IMUX. Measure with an

ohmmeter that the valve coil resistance is in the range 50-300Ω. Check the crimping on the connector pins for a bad contact.

E 35.n IMUX pressure sensor offset error (too low output)

Check that the indicated pressure sensor pins are properly inserted in the mating sockets on the PSB. Since the pins are fragile, check also that they are not bent or broken. Check the condition of the ribbon cable between the IMUX and PSB. Check that it is not pinched between the IMUX and the console aluminium bottom. Check with another “known to be good” PSB with sensors attached. Replace the IMUX if the error still is there. Check that the orientation (only if you have disassembled the sensor block) of the sensor s is OK. The sensor amplifier outputs can easily be measured at the respective test points on the IMUX.

E 37 Pressure sensor cable not properly attached to the IMUX

Cable is probably loose or not attached to the IMUX ribbon cable connector properly (all sensor signals simultaneously out of bounds). Check also that the PSB is mounted properly so all pressure sensor pins (4 x 4) mates with respective sockets. Check that the ribbon cable is properly manufactured (connectors the right way around - pin 1 to pin 1). Check with a known good PSB and replace the IMUX if necessary.

E 39 Drive (cooling) air valve control servo cannot maintain pressure to instrument

DETAILED DESCRIPTION OF ERROR MESSAGES

The proportional valve gets full power but still the measured pressure does not reach the required level. The most probable reason is that there is something reducing the air flow so that the pressure cannot reach the level required even if the control valve is fully open. Check for air tube kinks inside the unit and console arm. Check the condition of the incoming air pressure regulator and also the air filter. Check that the incoming air pressure is within recommendations. The control valve in the IMUX could also cause this problem. Replace the valve as a last remedy.

3.7 Foot control related error messages

E 51.n Cable from foot control is loose or connected into wrong connector on MCB

E 51.1 reserved E 51.2 Foot control is not responding

The foot control cable is disconnected from the unit, or the cable is open circuited, or the foot control has failed. Check if the foot control gets power by checking its that its internal yellow status-LED is blinking. Try to recalibrate the foot control, see page 2.6 “Calibrating foot control” on page H-15 for details.

E 52 Foot control is of new type, update MAIN software

The recently attached foot control is of a new type, of its software is not compatible with the MCB software. Please update the MCB software. The new software on the MCB is also still compatible with the older version(s) of the Prostyle Compact foot controls.

E 53 Foot control data error (cable short circuit)

The data signal is short circuited to ground. Check the condition of the foot control cable and replace it if necessary. Try with another foot control to determine the location of the problem. Check also the condition of the internal foot control cable going from the MCB to the foot connector at the rear of the unit base.

E 54.n Foot control calibration error

These errors inform that the foot control calibration failed for some reason. The decimal part number gives the details:

E 54.1 Foot control EEPROM write failure E 54.2 Foot control EEPROM read failure E 54.3 Pedal too far from the sensors, channel A E 54.4 Pedal too far from the sensors, channel B E 54.5 Sensor plate is too much tilted to either side, checksum error E 54.6 Sensor plate is too close to the PCB, channel A E 54.7 Sensor plate is too close to the PCB, channel B

E 54.8 Foot control re-trigger error.

Calibrate the foot control. If it does not help, check that the capacitance sector

plate on the pedal is not touching the foot control PCB, or is not too close to the

PCB. It is also possible, however very unlikely, that the foot control PCB is

defect.

3.8 Operating light related error messages

E 56 OP-light erroneously connected or short circuit in pushbutton

This error can occur only during selftest at power up. If the momentary push button is shorted during the test then this error is generated. The button could be damaged, or the reason can be a wrong connection so that the bulb and button are cross-connected. The electronics refuses to turn on the output power to the operating light, until the short has been removed (or the connection has been corrected). This feature protects the OP-light push button from destruction. Obviously the button should not be pressed simultaneously when powering on the unit, to avoid a false error.

E 57 reserved

E 58 Operating light bulb burned out

This error occurs when the operating light bulb has burned out. Replace the bulb.

3.9 Separator system related

E 59.n The separator is reporting an functional error

The separator is signalling the error output (either Metasys (59.1) or Dürr (59.2)). Please check the separator documentation.

E 60 The separator is not responding or the separator cable is faulty

The stand-by signal is missing from the separator (valid only for Dürr or Metasys). Either the separator is faulty, or the cable between the MCB and separator is faulty. Check that the separator is reaching a power supply voltage. Check that the separator cable is plugged in to the MCB properly.

E 61 Separator is flooded with too much water

This error can occur only if the unit is equipped with a Microvac separator. The error is generated if the water level inside the Microvac rises too high. The reason can be a too fast water flow to the separator compared with the handling capacity of the drain. Check the drain, clean the bottom cup under the Microvac. If necessary, replace the Microvac separator.

E 62 The separator is unknown

Technical Manual

The newly attached separator is of a new type and cannot be controlled by the MCB. Please update the MCB software. Check that the separator connector is properly connected and none of the wires are loose.

E 63 WMS error

3.10 Patient Chair related

E 64 Seat position potentiometer or its cable is faulty or disconnected

This error occurs if the output signal from the position potentiometer wiper is close to 0V. This indicates that the cable is disconnected or the wiper or the hot end of the pot is open-circuited (cable or pot fault).

E 65 Lift motor does not run or no signal from the position sensing potentiometer

There can be several reasons for this error, but they can easily be divided into 3 categories to be more easily understood;

a) If the motor runs and the chair’s lift mechanism moves:

The error must be in the pot, its cable or on the MCB. Check visually the condition of the pot. If the pot’s axle is rotating together with the worm screw then check the cable from the pot all the way to the MCB. Turn off the power and use and ohmmeter to do the checking. If the pot and its cable seems to be ok you can additionally check the reading from the pot with the help of the service mode 76 that shows the pot signal on the unit display. Connect an external pot directly to the MCB and use the service mode to check that the MCB is OK.

DETAILED DESCRIPTION OF ERROR MESSAGES

b) The motor does not run but there is a faint humming sound from the motor.

Check that the movement has not reached either of the mechanical limits. Is the seat overloaded (>150 kg load)? Is there any other mechanical obstruction? Check that the motor capacitor is properly connected and that the capacitor is OK. Check that the motor cable is OK (you should be able to measure the resistance of both windings at the connector that connects to the MCB).

c) The motor is completely dead.

Is the motor very hot? It is possible to overheat the motor if you run it continuously for more than about 2 minutes, or if the motor runs more that 13% of the time. When the motor heats up the built in over-temperature switch disconnects the common wire, resulting in a temporarily dead motor. When the motor cools down (this can take 10...20 min.) it returns back to normal operation. Check also the connector and cables to the motor if it is not overheated but still dead.

E 66 Lift motor or its position pot cable has a wrong connection

This error can occur only if you install a new motor or pot and either of these have a cable with crossed conductors. In other words, the pot signal (or motor running direction) is opposite to what it should be. Check that the cable(s) are according to the drawings.

This error could occur also if the motor direction relay on the MCB has failed. Check that the direction re-lay is toggling when trying to alternatively drive the mechanism in both directions.

E 67 Backrest position potentiometer or its cable is faulty or disconnected

Please refer to the explanation for the lift motor (ER64), since both motor drives are equal.

E 68 Backrest motor does not run or no signal from the position sensing potentiometer

Please refer to the explanation for the lift motor (ER65), since both motor systems are equal.
