Important information

ST	Patient chair
S video	This is an image signal split into color and brightness. Com-
	pared to composite video information, which is sent through a
	single line, this signal transmission facilitates images with less
	noise and higher definition. S video images have almost the
	same image quality as RGB images. The color depth is 16 mil-
	lion colors (True Color).
SW	Software
VGA	In this Service Manual, the RGB connection between PC and
	treatment center monitor is designated as VGA. It does not rep-
	resent the resolution of the image signal. Sirona also uses the
	designation XGA instead of VGA frequently, e.g. XGA cable.
TR	Support arm
VAC	AC voltage

	2.1 General service aids
Image quality/image failure	In case of poor image quality, the “Auto Setting” function of the monitor
	can bring about an improvement.
	A reduction of the PC graphics card “Refresh rate” setting to 60 Hz can al-
	so bring about an improvement in image quality. After display parameters
	on the PC graphics card have been changed, the “Auto Setting” function
	of the monitor should be activated once again.
	If no image appears on the monitor, you can connect the plug of the VGA
	cable of the treatment center located in the junction box to the VGA output
	of a notebook for test purposes.
	A second possibility of ruling out a possible cable problem is to replace the
	VGA cable run in the treatment center by a standard VGA cable between
	the PC/notebook and the monitor.

2.2.2 Dentist element with SIROCAM 2

		The SIROCAM 2 is characterized by a high-quality optical sys-
		tem. The lighting is located in the dentist element and is run	C2+
		through a fiber-optic cable to the camera head.
SIROCAM		The Sirocam 2 is intended for the smile line range close to the teeth as well
		as for the full face range. The distance adjustment is continuously variable.

The housing is made of titanium and the lens protective sleeve can be removed and sterilized. The image memory is not located in the camera, but on the VGA converter PCB.

To compensate for camera-specific influences on the color settings, data for the analog camera PCB KB is stored in the camera head.

LED

The unit electronics (PCB ADX) detects the presence of the optional camera system in the dentist element from an identifier resistor on PCB AKV. In this case, the camera is treated by the unit electronics in the same way as an instrument.

When removal of the camera is detected by the photoelectric light barrier at the holder, information about the active video system appears on the LCD panel, and the software allows switching between live image, white screen and still image (freeze) by means of the foot switch (or keyboard).

All the other instruments of the dentist element – apart from the Sprayvit – are blocked. If the camera is removed after an instrument has already been removed, it switches directly to live image mode; switching by means of the foot switch is then no longer possible.

The video signal of the camera is processed to form a standard signal (S video) on PCB KB.

A red LED indicating the status of the communication to the camera head is located on PCB KB:

LED off	Camera OK

PCB AKV	The interface between the camera unit and the unit electronics is PCB AKV,
	on which the galvanic isolation between patient circuit and the operating and/
	or control voltages of the camera system is implemented. The camera/video
	functions are contacted to protective ground.

AKV

Functional units on PCB AKV

Switched-mode power supply for halogen lamp and fan:

The 16VAC from the transformer in the junction box are rectified on PCB AKV and converted into a supply voltage of approx. 11.5VDC for the fan and the halogen lamp.

This switched-mode power supply is activated by a control signal from the logic unit of the AKV.

Power supply for the camera and its electronics with galvanic isolation:

A DC/DC converter with galvanic isolation converts the rectified input voltage of PCB AKV into a supply voltage of approx. 12VDC for the camera and the camera electronics. This converter is activated by a control signal from the logic unit of the AKV.

	Processing of control signals/status signal of the unit electronics/
	camera with galvanic isolation:
	The corresponding control and status signals between the unit electronics
	and the camera electronics are galvanically isolated from each other by
	optocouplers.
	These signals are supplied to a logic unit, which for instance generates
	the run-on time of the fan, enabling of the above power supplies for halo-
	gen lamp and camera electronics, as well as safety shutdown of the halo-
	gen lamp on overtemperature in the lamp box.
	Power supply for the logic unit:
	With the help of voltage regulators, the necessary supply voltages are
	generated for the two galvanically isolated logic units (+5 V and +5 Viso).
Description of the basic functions on	When the supply voltage is applied, the green LEDs V107 (+5 V) and
PCB AKV:	V106 (+20 V) light up.
	The unit electronics (PCB ADX) sends a control signal to PCB AKV when
	the camera is removed and active (yellow LED V118 (CamIn) is on), and
	the power supply for the camera and its electronics is enabled
	(green LEDs V110 (+12 Viso) and V113 (+5 Viso) are on).
	When the camera is plugged in, the camera electronics send a “Camera
	OK” status signal back to PCB AKV (yellow LED V114 (StatusOut) is on),
	through which the switched-mode power supply for the halogen lamp and
	the fan is activated (green LED V304 (Lamp+) is on).
	With an active temperature sensor (overtemperature case, LED V200
	(Temp. sens) is on), the halogen lamp is turned off, but the camera and fan
	functions remain as they are.
	When the camera unit is deactivated by the unit electronics, the fan con-
	tinues running for a short time.
	The two control signals Control_1 and Control_2 are currently not used.

	The video converter has the task of converting an S video signal
	into a VGA signal.
VGA video converter	The image memory function (switching between still/live image) as well as
	the white screen function are controlled through the control inputs on connec-
	tor X2. If an S video signal is no longer present in live image mode, then the
	system switches to a black screen.
	With a PC connection, the VGA converter is not required! The white screen is
	generated by the PC.

CJ

PC connection

The 12VDC output voltage of the power supply unit is required for the monitor and the VGA converter module.

The white screen control as well as switching between still/live image of the converter is performed by PCB CJ (X80).

With a PC connection/second monitor, PCB CJ conducts the function key commands through the RS232 interface (X11) to the PC. The RS232 commands are structured according to the Mouse Systems Protocol, whereby only the first byte is used. Both the control outputs (X80) and the RS232 interface (X11) are galvanically isolated, so that they can be connected directly with the PC or converter.

The transmission parameters are: 9600 baud, 8 data bits, no parity, 1 stop bit. No protocol.

PC connection of the video application/second monitor

The VGA cable of the PC is connected with the VGA cable of the monitor and fastened with a retaining clamp on the retaining plate of the monitor power supply unit.

The RS232 connection is plugged into PCB CJ at position X11. (Check for proper fit, especially after service work in the area of the junction box)

The grounding cable of the PC is fastened to the proposed grounding point.

For PC connection of the video application only:

The S video cable of the PC is connected with the S video cable of the video application and fastened to the retaining plate (make sure there is correct contact with the metal parts of the connector).

2.2.4 Monitor

The monitor has two VGA inputs; VGA input A should be preferred.

The 12VDC power supply is made through the 4-pin POWER MINI DIN plug.

Refer to the operating instructions for operation of the monitor. The LED next to the on/off switch can assume three states:

	green	there is a VGA signal present
	orange	there is no VGA signal present
	off	monitor is switched off or no voltage available

2.2.5 Video application with PC interfacing

The camera S video signal as well as the control signals generated by the treatment center are sent to the external PC for further processing.

The analog S video signal is digitized on the frame grabber card of the PC and then converted on the graphics card of the PC into an analog VGA signal for display on the treatment center monitor.

When the camera is removed from the dentist element, a live image is transmitted via the S video cable and a removal signal is sent to the PC via the RS232. A window with the live image is automatically opened by the removal signal in the Sidexis/Videxis software.

When the camera is deposited, a control signal sent by the treatment center closes the window with the camera image, and the video signal is switched off.

Further control signals sent from the treatment center to the PC via the RS232 are used for:

switching over between the live and the still image (by means of the foot switch)

saving the still image

switching to white/black screen (white and black screen are generated by the PC)

as well as further freely configurable PC control functions

SIVISION 3

					3.1		Function of the camera
						The SIVISION 3 video application is offered with two camera types:
						The SIROCAM 3/C is designed for integration in all units. The C3+/C4+/C5+
						can also be integrated in the assistant element. There is also a compact so-
						lution with the SIROCAM 3/C, which can be attached to units that are al-
						ready installed.
						The SIROCAM 2 was offered for the C1+ and C2+ units until 03/2003.
SIROCAM C						The SIROCAM C is an intraoral camera designed especially for the range
						close to the teeth and the smile line.
SIROCAM 3						The SIROCAM 3 is the successor to the SIROCAM 2.
						The optical system was improved and the electronic concept of the
						SIROCAM C was adopted. For example, the interface between the
						SIROCAM 3 and the SIROCAM C is identical.
						For the SIROCAM 3 and the SIROCAM C:
						The object is illuminated by white LEDs. These LEDs heat up the lens of the
						camera. This prevents the lens from misting over during treatment.
						The camera has an internal quad image memory. The SIROCAM 3/C can be
						supplied with a direct voltage of 8.5 to 12VDC. The control signals reach the
						camera from the treatment centers or from the PC via a serial interface.
						In treatment centers without a serial interface, the camera can also be con-
						trolled through discrete inputs. A reed contact integrated in the camera
						enables operation through an additional holder mounted on the instrument
						rack. The camera is switched on or off by a magnet in the instrument holder.
SIROCAM 2 (discontinued 03/03)						The SIROCAM 2 is characterized by a high-quality optical system. The hous-
						ing is made of titanium. The lens protective sleeve can be removed and ster-
						ilized. The lighting is located in the dentist element and is guided through a
						fiber-optic cable to the camera head. It is intended for the range close to the

teeth, the smile line and the full face range. The distance adjustment is continuously variable.

The quad image memory is not located in the camera, but on the camera module integrated in the dentist element.

A reed contact integrated in the camera enables operation through an additional holder mounted on the instrument rack. The camera is switched on or off by a magnet in the instrument holder.

To compensate for camera-specific influences on the color settings, data is stored in the camera head. With the introduction of SIVISION 3, apart from a data record for the analog camera PCB KB, a separate data record for the digital PCB AD 2 is stored in the camera. These cameras are identified by the suffix “B” at the end of their serial number. An additional data record can be determined and stored with the white balance function, especially when using cameras featuring only an analog data record (without “B” suffix) in SIVISION 3 configurations. Thus it is possible to optimize the color setting on existing SIROCAM 2 cameras in dental practices on treatment centers with SIVISION 3.
