parts: Switch the unit OFF.

Protective ground connection The building water supply is at protective ground potential and must not touch

the fuse box of the chair.

Warning! 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!

Operational reliability To ensure operational reliability, the use of mobile telephones in the practice

or hospital area must be prohibited.

Troubleshooting: If you encounter difficulties, search in the error catalog first and proceed

3 Points to observe during assembly

3.1 Patient chair

The patient chair can be moved without dentist element only if the

4-way foot control is installed.

3.2 Protective ground / electronic

ground

An equipotential bonding conductor must not be connected. If

present, isolate it!!

Measure the protective ground against electronic ground.

Measure continuity from A to B:

The continuity tester must not beep.

A meter must show a reading of ∞ Ω.

3.3 MV1 / AD3

During assembly, decide whether the MV1 (version with disinfec-

tion system) or pressure reducer AD3 (version without disinfec-

tion system) is to be installed (see installation instructions).

3.4 Connecting the water Unit/assis-

tant element:

The 16V supply cables must be connected according to the color

coding to terminals X1, X2 and X3 on PCB CF in the connection

box.

3.5 Assistant element:

The 16VAC and 24VAC cables are interconnected at the neu-

tral 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 ele-

ment may be destroyed.

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 – 2 D 3370.076.01.06.02 10.2005

4 What happens after switch-on?

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).

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 soft-

ware 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

NOTE

The clock chip is located on PCB CJ in the connection box (chair).

If the clock is functioning properly, CAN communication between the compo-

nents 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.

Interrupt sanitizing by simultaneously pressing the SPRAY ON/OFF and

CHIP BLOWER keys, AP SW version 5.4 and higher press intensity

. 2. ... whether the instrument configuration at the instrument

flanges has changed since the last power ON.

This is detected by the different instrument hoses and their

coding.

If it is determined during power-up that the instrument config-

uration 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

– Ultrasound to 20

CAUTION

The heater and the light in the SPRAYVIT remain turned off during

initial start-up.

The water pump must execute at least 20 strokes before the heat-

ing 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 com-

municate 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 communica-

tion) are arranged in the following order:

The individual signals - for example, cuspidor flushing, tumbler filling, instru-

ment motor ON and clock time - are transferred and relayed from component

to component via this system.

4.2 Checking the CAN BUS

Is the clock running ?

If not, check whether the CAN connections are crushed, and

check for short-circuits and loose pins on the connectors.

NOTE

Tip: The clock chip is situated on PCB CJ in the chair (connection

box).

Turn on SIROLUX FANTASTIC from the dentist side and from the

assistant side.

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 den-

tist 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.
