3.5 Assistant element:
The 16VAC and 24VAC cables are interconnected at the neutral conductors. If the conductors are switched, there will be
a short-circuit and fuse F 13 on PCB CF will blow. If no
medium time-lag fuse is fitted, PCB HP in the assistant element may be destroyed.
bеЦдблЬ
General Ensure proper installation of hoses and cables, do not allow them to be
crushed.
If hoses are interchanged, water will penetrate into the air supply system. This
may result in a failure of solenoid valves.
Crushed hoses and cables may cause failures on the entire treatment center.
Check the position of cables and media hoses before tightening any nuts.
EMC installation work EMC work that has not been performed correctly may result in faults which
are difficult to detect later on.
When all the installation work has been completed, measure the contact
resistance between protective ground and electronic ground (see 3.2 or
installation instructions).

4.1 Sequence of events
The unit transformer T1 is supplied with power via the unit main
switch S1.
The transformer supplies a voltage of 25VAC which is then rectified.
This results in a DC voltage (approx. + 35VDC).
S1
T1
READY
"READY" indicates that the treatment center is ready to
operate. This does not mean, however, that the treatment
center self-tests have been completed without errors.
Components AE, HE, WE and the chair (AK) are now supplied with + 35VDC
via fuse PCB CF, i.e., the required voltages (e.g., + 5V for logic, + 24V for
solenoid valves) are generated on the PCBs in the different components.
The 16VAC and 24VAC voltages in the unit are used primarily to power the
SPRAYVIT, water heater, camera supply and the halogen Polylight.
When the supply voltages are applied to the different components, the software on the PCBs powers up (boot procedure).
A self-test is performed on the treatment center in this phase, and is audible
(for example, solenoid valves respond and relays trip).
Current is measured to detect whether any of the components (solenoid
valve, relay, or motor) has 1. a short-circuit, 2. an open circuit.
These evaluations are written into the service info memory of the individual
components AE, HE, WE and chair (AK).
CAUTION
A message relating to an open circuit does not necessarily indicate a fault. If
an open circuit is detected and the component is nevertheless functioning
completely, the current measurement is only out of tolerance.
When the self-test has been completed, the LCD indicates READY.
The clock is also displayed
i
NOTE
The clock chip is located on PCB CJ in the connection box (chair).
If the clock is functioning properly, CAN communication between the components is generally in order.
The software recognizes ...: :
1. ... whether the treatment center is in a sanitation mode.
This signal comes from the water unit, PCB WE, via CAN communication.

If this is the case, it must be terminated or properly interrupted.

This is detected by the different instrument hoses and their
coding.
If it is determined during power-up that the instrument configuration differs from the stored configuration (on the ADX PCB),
the instrument values will be set as follows:
– Highspeed handpiece to full power
– 1. Motor to 40,000 rpm
– 2. Motor to 20,000 rpm
HP
– Ultrasound to 20
CAUTION
The heater and the light in the SPRAYVIT remain turned off during
HC
initial start-up.
The water pump must execute at least 20 strokes before the heating and light are enabled. This applies to the SPRAYVIT both in
the dentist element and in the assistant element.
If the ADX PCBs in the dentist element and HC are replaced, the
pump must execute an additional 20 strokes.
When the self-test has been completed, the individual components can communicate with each other via a data bus system.
This system is called: "CAN BUS"

CAN BUS, data communication between PCBs C5
The four components chair, dentist element, assistant element and water
unit are interconnected via a CAN serial interface.
The individual CAN drivers (transmitters and receivers for data communication) are arranged in the following order:
Chair = board CJ
Water unit = board WE
Assistant element = board HF
Dentist element = board ADX
Dentist element = board AP
Assistant element = board HC
+
The individual signals - for example, cuspidor flushing, tumbler filling, instrument motor ON and clock time - are transferred and relayed from component
to component via this system.

NOTE
Tip: In this way you check the CAN cabling and the functioning of
many PCBs.
The "Turn on SIROLUX" key information is passed from the dentist element panel (AP) to the connection box (CJ) and from there
on to the water unit (WE).
Here PCB WE drives the SIROLUX dimmer PCB.
It then turns the SIROLUX light on.
In addition, the relevant LEDs on the panels are activated by a
CAN message from the water unit.
Check the CAN BUS using the foot switch.
Move the chair with the cursor.
In this way you can test the section between foot switch, chair (connection
box) and panel.

NOTE
Information: You can move the chair with the 4-way foot control.
Tip:The 4-way foot control is not connected to the CAN; the chair also moves
when communication is no longer possible.

PCB
CJ
If you measure approx. 60Ω between X34.1B and X34.2B,
the CAN circuit is OK.
If you measure approx. 120Ω between X34.1B and X34.2B,
the CAN circuit is open-circuited.
2. Locate the open circuit.
Measure the CAN_High and CAN_LOW circuits one after the other.
e.g.: Measure CAN_High between X33.2B and X34.2A
– If you read approx. 2 -3
Ω, this circuit is OK.
– If you read ∞, both this circuit and CAN_LOW are open-circuited.
– If you read approx. 240
Ω, this circuit is open-circuited and the
CAN_LOW circuit is OK!
If an open circuit is found, it is now possible to individually check the
nodes on PCB CJ in order to locate the open circuit.
MeasureX33.2B > X34.2B >>> If there is an open circuit, then:
measure X33.2B > X31.2B >>> If no open circuit can be measured here,
i.e. you measure approx. 2 - 3
Ω, then the open circuit must be located in
the connection to the assistant element!
At this point it is highly probable that the open circuit can be easily located by
simply checking the cables and connectors, since the number of possible
errors is greatly reduced.

The panel control PCB [AP] in the C2+, C3+, C4+, C5+, M1+ and
+
forwards the request to operate from the panel to the relevant
M1
components via the CAN cable.
Green LEDs on keys: The green LEDs are status LEDs. The status (ON, OFF, FLASH-
ING) is signaled back by the components concerned to the panel
via the CAN cable. If the function is not activated, search locally
in the respective components. It is possible that an interlock is
active or that the option corresponding to the function has not
been installed.
Exception: The LEDs of the manual chair adjustment keys are
addressed directly by the panel.
Yellow cursor LEDs: The yellow cursor LEDs indicate the location of the cursor posi-
tioned with the help of the foot switch.
This cursor control can be deactivated in the Mode dialog.
Key click: Every key actuation on the panel and foot switch (exceptions: 4-
way foot control and keys on the tilting part) is confirmed by a key click.
This key click is generated on the panel.
If a key click is generated in response to a key operation, it can be assumed
that the keyboard is in order.

5 Description of the functions of ...
Power supply PCB CJ always requires two power supplies:
approx. 35VDC and 115VAC.
Other voltages are derived from the 35V supply voltage.
5V, 600mA (short-circuit-proof) digital logic
24V, 5A (short-circuit-proof) power electronics
5Vref, 20mA (short-circuit-proof) external potentiometers
5.5V, 100mA RS232 and Sivision (with optical isolation)
A 4.0V reference voltage is made available at the analog input of the controller. This reference voltage is required for diagnostic purposes and for electronic control.
There are three green LEDs (+35V, +24V and +5V) for power supply monitoring.
The 115VAC voltage is required for driving the lift and backrest motors. The
AC voltage is fed to the solid-state relays via a safety relay.
The freedom of movement of the motors is restricted by the potentiometers
and limit switches. In addition, there are other safety switches which can interrupt the chair movement immediately. If a safety switch is active, the motor is
blocked in a certain direction of travel.
The cuspidor safety switch is a special case. If this safety switch is active, the
115VAC are turned off by means of the safety relay and the red LED (115V
relay) lights up. The two motors (lift and backrest) are blocked.
Controller At the heart of the circuit is a powerful 16-bit controller (C167CS). The con-
troller controls and regulates the complete range of functions on PCB CJ.
The external oscillator frequency is 5MHz. A PLL boosts the operating frequency internally to 20MHz.
The reset signal is generated by a reset chip. If the voltage drops below
4.63V, reset is activated. The red RESET LED lights up during reset. When
the controller has finished booting, the LED is switched off. There is a reset
button on PCB CJ. This button can be actuated at any time to generate a
reset.
The controller features a monitoring unit, known as watchdog. If the watchdog
timer is not reset within a fixed timeout, the unit triggers a reset. This reset
changes the on-chip I/O to the reset state. For monitoring the watchdog control, an external port (P3.2) is toggled every time the watchdog is reset.
The controller features an internal CAN controller. The CAN bus forms a network within the treatment center. All PCBs are connected to the CAN bus.
Information can thus be exchanged between any two components via the
CAN bus. The beginning and end of the CAN bus are located on PCB CJ.
A terminating resistance of 120 ohms is defined at either end of the CAN
cable. 60 ohms are then measured during operation.
The DC motors (headrest motors and travel track) are driven with a PWM via
the controller. The direction of rotation is determined by switching a relay.
There are LEDs fitted at the output stages that indicate the direction of movement.

NOTE
Both conventional solenoid valves and proportional valves can be fitted on the
solenoid valve block.
A coding resistor in the MV cable enables electronics/software to decide which
type of control must be used.
Currently not available.
The foot switch, 4-way foot control and controls on the headrest are coded. If
a part is fitted while the unit is running, the configuration is updated immediately.
The yellow USER LED lights up when a switch is operated.
There is an RTC (real-time clock) on PCB CJ. The time on the treatment center is set by PCB AP.
Non-volatile data (such as error memory and chair parameters) are stored in
the battery-buffered SRAM.
There is a resistor network on the PCB for identifying the hardware status.
Battery The battery is a lithium type battery (Sonnenschein, type SL-350). These bat-
teries are characterized by their high capacitance at a very low self-discharge
rate. The battery voltage (VBAT) is 3.6V. When the unit is switched off, the
battery supplies the RTC and the 32KB SRAM. Battery life: > 10 years.

Requirement: Customer Service can recognize the production date of the battery to substi-
tute the PCB or change the battery, as necessary.
Safety switches Chair safety switches:
The safety switches inhibit the respective hazardous directions of chair
movement by means of hardware.
There are three safety switches associated with the chair:
Headrest SS (headrest HR), backrest SS (backrest BR) and toeboard SS
(toeboard TB).
Cuspidor safety switch:
When the cuspidor is swung in, the lift and backrest motors are blocked.
+
HE support arm safety switch, C3
The chair motors are blocked during lifting or lowering of the support arm.
/C4+/C5+/M1+:
Emergency Stop The movement stop of the lift and backrest motors can be activated by the
EMERGENCY STOP signal.
The motorized chair movement is completely disabled.
If the emergency stop is active, the red EMERGENCY STOP LED lights up.
Diagnostics When the supply voltage is applied, the green LEDs light up:
z +35VDC supply voltage (approx.)
z +24VDC supply voltage
z +5VDC supply voltage
The states of all inputs are indicated on PCB CJ by means of three LEDs: SS
LED (all safety switches), LIMITS LED (all limit switches) and USER LED (all
switches).
The error states of the outputs, relays, and solenoid and proportional valves
are indicated by the D-ERROR (drive error) LED.

Level sensor DS31, which is located in the mixing tank, sends a
signal to PCB WE in the water unit when the water reaches a low
level and indicates this by means of LED V76.
After the "Low water level" signal has been detected by PCB WE,
pump P performs a precisely defined number of strokes after a
load has been activated. PCB WE then generates a CAN data
signal, which is received by PCB CJ in the chair. MV1 opens and
water flows into the mixing tank. PCB WE then registers the time
that elapses until DS31 is reactivated and calculates the time until
the tank is filled. When the time has elapsed, PCB WE sends a
CAN data signal to PCB CJ, and MV1 closes.

was triggered.
If the bowl flushing key is pressed for more than 3 seconds, the

The motor setting appears on the LC display of the dentist element
(only if PCB ADX in the dentist element detects that a Siromot module is
present).
The solenoid valve module (MV21.1 to 4) assigned to the motor is activated
(one of LEDs V69, V74, V79, V110 on PCB ADX lights up, depending on
which module is activated).
The relay for motor and instrument voltage assigned to the motor is activated
(one of LEDs V57, V60, V63 on PCB ADX lights up, depending on which relay
is activated).
Actuate foot switch S1.
PCB CJ in the connection box/chair then sends a CAN data signal to PCB
ADX in the dentist element and starts the motor.
PCB ADX then sends a CAN data signal to PCB CJ and turns on the cooling
air (MVP1) for the motor (if a proportional valve is installed, with the intensity
preset under MODE).
If there is a problem with the CAN data communication, or if the solenoid
RPM
valves are recognized as faulty, the motor is not started. In addition, the ADX
software queries the cooling air pressure using pressure sensor P21.
If a cooling air pressure of < 0.5 bar is detected, ADX turns off the motor function.

The heater and the light in the SPRAYVIT remain turned off during initial startup. To vent the water pipes, the water pump must have performed at least 20
strokes before the heater and the light are enabled. This applies to the

The Polylight is operated with 16VAC from the power supply.
A switch-on pulse via the light button (if fitted on the assistant element) switches on the electronics.
The same pulse deactivates the electronics the second time.
A checkback signal to the assistant element indicates whether the
Polylight is still active.
This signal is also used to turn off the heating voltage (SPRAYVIT and spray
water heater); this protects the system from overload. The fan is driven by
board PL.
6.9 ... Polylight Mini LED in the assistant/den-
tist element
As soon as the treatment center is switched on, the MINI LED DC/DC module
(MI) is supplied with a 35VDC voltage.
Located in the treatment center is a
DC/DC converter which generates
the 5VDC supply voltage for the MINI
LED handpiece from the 35VDC
voltage.
In contrast to all other treatment center instruments the MINI LED is not
detected by the software, and therefore is not indicated on the dentist
element display.

The PCB returns a status signal via the CAN bus.
This signal causes the AP controller
to activate the green LED on the X-ray image viewer key
when PCB WE has switched on the X-ray image viewer.
2. With a PC connection of the camera or second monitor function, an RS232
command is sent via the interface of board CJ to the PC, which can generate a WHITE SCREEN (factory setting). No status feedback signal is generated, i.e. the green LED on the X-ray image viewer key does not light up.
3. X-ray image viewer on the dentist element (only C2

9 Option list
The option list is output after the hardware (HW) and software (SW) version
numbers during output of the service code list and should always be consulted in a fault scenario.
If an option is not detected (i.e. output) despite the fact that is installed, the

Up to CJ SW version 5.3 Start the error output using the Mode dialog.
To speed up the output when a notebook computer is connected, the complete service information is output to the notebook computer within a few seconds before output to the panel display commences.
Following this, output to the panel display starts at the customary slow rate to
allow you to take notes if no notebook computer is available.
With CJ SW version 5.3 and
higher
Starting with CJ SW version 5.3, the service code can be read in two ways:
1. Using the Mode dialog as described in section 10.1., service codes are
only output on the dentist element display.
2. By pressing the ENTER key after the notebook computer/PC has been
connected and the Hyperterminal program started.
The service codes are output to the notebook computer/PC only. It is not
necessary to start the output via the Mode dialog of the AP.
