1.2
Warning and safety information
Prior to opening the unit, connecting a measuring instrument or replacing parts, switch the treatment center OFF.
The building water supply is at protective ground potential and must not touch the fuse box of the chair.
If there is a protective ground contact, the patient or user may be exposed to tension in the event of a fault - risk of electric shock!
To ensure operational reliability, the use of mobile wireless phones in practice or hospital environments must be prohibited.
If you encounter difficulties, search in the error catalog first and proceed according to the instructions given there.
CAUTION
When opening the unit:
Please observe the usual precautionary measures for handling printed circuit boards (ESD).
Touch a ground point to discharge static electricity before handling any components. Use an ESD wrist band.
Connect it to the protective ground wire.

Function of the HF+ board
Generates the high frequency of the Sirotom handpiece.
The one pin of the high voltage is the tip of the handpiece, the other is the ground / casing.
Control via CAN.
Overheating guard at the end phase.
Generation of the operating tone with active HF.
The HF module is switched on for a few seconds after the dental treatment center is switched on. During this period the
HW/SW status is queried and the module carries out a self-test. Subsequently the module is switched off again. When the
HF handpiece is removed, the module is switched on again and carries out a brief self-test. When the handpiece is returned to its place, the module is switched off again.
For operation in this dental treatment center, the code bridge X10 must be set to position "C1" and the code bridge at X7 must be connected to Pin 2 / Pin 3.
When HF is activated, the video circuit is shut off in the power pack and switched on again when the handpiece is replaced. This is necessary so that no interference is visible on the screen when HF is active. When the video circuit is switched off, the USB power supply and thus the USB camera are switched off.

Function of the NHT board
The NHT board is controlled by the NHE board. The keyboard is evaluated with a key matrix and the LEDs are activated directly.
The LEDs are always switched on by the NHE software when they receive the acknowledgment from the corresponding component that the function has been activated.
There is no acoustic feedback when the key is activated.

3.1
Switching the dental treatment center ON/OFF
After switching on the operating power supply, the boot loader is started on all boards. The software of the NSA board checks all components to see whether they are up-to-date.
If they are not, an update is started (this can be done after a board is replaced).
If the software is up-to-date, it will be given approval to start, the corresponding booting LEDs go out and the application software is loaded.
The green LED on the user interface is electronically coupled directly to the 36 V operating voltage.
If the dental treatment center is switched off at the user interface, the water unit emits a short beep to confirm the shutdown.
If the DNA option is installed, the DNA tank is emptied before the dental treatment center is really switched off. In rare cases this may take up to 15 seconds. After the unit is switched off via the user interface, the treatment center can switched on again via the user interface if it has not been switched off at the main power switch.

CAN BUS
In the treatment center there are several CAN networks.
Thestandard CAN runs all of the control units for the treatment center, software updates and service support.
The S CAN runs only PC software functions for the user interface.
The motor CAN runs all commands for controlling the motorsM1 / M2 / M3 from theNSA board to the three DCFU boards.
After the treatment center is switched on, all components and software are queried and displayed in the set-up dialog. If the connection fails during operation, the unit must be switched on again.
SET-UP key
C
Clean Setup
> 2s
If an installed component is missing here, this board and the CAN connection to the user interface (NAKboard) must be checked.
Each node that loses its standard CAN connection to the central error memory in the NSA board flashes cyclically 2x at its
error LED. -> Check the CAN bus.
In each CAN network there are 2x 120-Ohm resistors, that, measured in parallel on the CAN line, result in 60 Ohms. If you measure 120 Ohms on the CAN line with an Ohm meter (when the dental treatment unit is switched off), there is a disruption in the line.
In the case of a disruption, measure the connections between the connectors.
For example:
Check CAN
+
: NSA board, X1.5 to NAJboard X22.5:
0 - 3 Ohm = OK
00 Ohm = line disruption
240 Ohm = line disruption CAN+ but CAN- is OK

Patient chair
3.4.1
Stand-alone installation function
To operate the chair in stand-alone mode, the installation connector must be connected to the SDI connector of the assistant element (on the chair). This connector closes off the CAN, simulates the safety switch in the assistant element and a bridge lets the NSA board detect the connector.
If the patient chair does not find any NAJ board while booting, the four-way switch functions on the foot control like a fourway foot switch. If the four-way foot switch and/or tilt component switch are present as options, these will function to support the set-up phase and operate the patient chair without the dentist element/assistant element.
Once the NAJ board is detected, patient chair travel will be carried out only with "approval of the NAK board".
During movement of the patient chair communication between the NSA and NAK boards will be monitored. If the communication is disrupted, the patient chair travel will also be disrupted or not started at all.
3.4.2
DCFU motor control
In the DCFU board, the motor parameters and motor allocation/addressing are stored for the motor to be activated.
There are two types of motor: one large motor (lifting motor) and 2 small motors (for inclination and backrest).
After the replacement of a DCFU board, the NSA board determines via the "reference travel" function which DCFU board is connected to which motor and will transmit the corresponding motor parameters.
During the reference travel, the motors are moved slowly to the end positions and the software of the NSA board stores those positions.
During operation, whenever a reference point is crossed via a light barrier at X5, the calculated position is compared with the actual position and corrected.

Service support with the PC
The program "Sirona Dental Unit Management Console" (Sirona DUMC) is available to support the service engineers.
This program provides the following services:
•
Service management
(Readout and storage of service information)
•
Data management
(readout, storage, reloading of data in the treatment station, if for example boards must be replaced or if user-specific settings are to be transferred from one dental treatment center to another)
•
Firmware download
(Determine the version of a dental treatment center, download the new firmware, synchronize the firmware to a valid release, e.g. after individual boards have been replaced).
For more information about this program, please refer to the DUMC user manual: 61 94 489 D3509

PC control via SIUCOM plus
6.2.1
Control of PC programs via the treatment center
SIUCOM plus enables you to control PC programs via the Sirona treatment center TENEO. The PC functions can be operated via the user interface of the treatment center (touch screen) or the system foot control.
6.2.2
Ethernet connection is required.
This is achieved through communication of the treatment center with the PC via the Ethernet interface and the practice network. The function codes generated by specific operations in the treatment center are assigned to the desired PC functions in the SIUCOM program. Under certain circumstances it is therefore possible to start, terminate and control PC applications.
6.2.3
Third-party programs can also be controlled in this manner.
The SIUCOM plus PC program provides the Sirona SIUCOM plus interface for operating functions inside PC programs of other manufacturers.
The operating functions provided by the manufacturer of the SIUCOM pluscapable PC application can thus be triggered from the treatment center.
For further information, please see "Installation and Configuration - SIUCOM plus" SN: 6084367.
