3 Points to observe during assembly

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).

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

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.

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 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

– 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 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"

4 What happens after switch-on?

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.

Turn on SIROLUX FANTASTIC from the dentist side and from the assistant side.

S P

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.
