1.2 Summary of Key Operation and Maintenance Activities

This section presents the key points that a DeFTOS operator and supporter should be aware of.

The motor will go to full speed when the Panel/Foot Switch control is switched to foot switch if the foot switch is not connected.

The compressor/vacuum pump may not restart if there is a vacuum on the vacuum line, make sure the waste container is connected to the system.

DO NOT autoclave the motor.

If a sudden loss of vacuum is experienced it is probably caused by a full waste container.

If there is low suction it is probably caused by a leak or loose connection.

Check filters and water traps at the end of each day.

If the hand piece leaks from the motor, tighten the hose connection at the base of the motor, hand tighten only, DO NOT use any tool.

If the hand piece leaks from the interface with the motor, replace the motor o-rings.

Take care to connect the motor hose to the motor, the threads are very fine and easy to cross thread.

Take care when connecting the motor tubing to the base unit, the locking collar locks with only a 1/16 turn click.

Take care when connecting the foot switch to the base unit, the locking collar locks with only ¼ turn.

Take care when removing the main circuit board to avoid damage to the control panel label. The control panel label is “taped” to the button control circuit board with an adhesive. The button control circuit board is connected to the main circuit board via 2 connectors. Carefully unplug the main circuit board from the button circuit board to avoid damaging the label.

If the 3-way syringe does not work, check the installation of the valve in the handle, make sure it is fully inserted into the handle and locked with a twist.

The compressor bleed valve will make a hissing noise immediately after the compressor is turned OFF.

Make sure the frequency of any load connected to the duplex outlet is the SAME AS the main power frequency.

The power rating of the duplex outlet is 100VA.

The hand piece motor will get warm if the fiber optics is used continuously because the fiber optic bulb is mounted in the motor housing.

The hand piece motor requires cooling air. Motor damage may result if the motor is operated for extended periods without cooling airflow. If cooling air to the motor is lost the Low Cooling Air To Motor LED will come on and the motor will stop. To restart the motor, press the speed increase button.

If the vacuum pump is left ON continuously the controller will turn it OFF if there is NO activity of the hand piece motor for approximately 12 minutes. It will then blink the Compressor ON and Vacuum Pump ON LEDs to indicate that the vacuum pump has been turned OFF. To restart normal operation press any button on the control panel.

It is possible for the vacuum shut-off valve in the waste container to activate prematurely and/or stick if it has not been cleaned completely. To restore flow If the valve activates prematurely you must release the vacuum on the valve. To release the vacuum just turn the vacuum pump OFF and open the HVE valve, this will allow the valve to OPEN.

1.3 System Description

The PortaBELL™ II DeFTOS is a state-of-the-art system utilizing the latest electric motor driven hand piece technology to meet the demanding needs of the modern mobile dentist.

The system incorporates all of the functionality to perform any dental procedure from cleaning to oral surgery. The system includes an electric motor, with or without fiber optics, high speed hand piece, low speed hand piece, air/water supply, air/water syringe, high volume evacuator (HVE), saliva ejector, and variable speed foot switch. In addition an optional FDA cleared scalar and curing light are available.

The system is lightweight and totally self-contained. The system includes an oilless air compressor and vacuum pump that provides air to the water and air supply subsystems and suction for the saliva ejector and HVE, a self-contained water supply for hand piece coolant and oral irrigation, and a waste container for collection of liquids and solids from the HVE and saliva ejector. The system supports a variety of standard electric motors and all E-type connected hand pieces.

The system will operate on any power from 100VAC to 240VAC, 50 or 60 Hz without the need for a transformer.

The entire system can be quickly assembled or disassembled and packs into one molded shipping and storage container for safe transport and storage.

The system components are shown and identified in Figures 1.3-1 and 1.3-2.

1.4 Principles of Operation

The system is composed of an electric power subsystem, an electronic control subsystem, a compressed air subsystem, a water subsystem, and a vacuum subsystem. Each is described below.

The principle of operation is simple, refer to Figures 1.4-1 through 1.4-5, the compressor pressurizes the air storage tank. Compressed air is provided to the motor for cooling, the hand piece for chip air, the air/water syringe, and the water reservoir, refer to Figure 1.4-1. Water is forced from the water reservoir by the compressed air and flows to the hand piece and air/water syringe. Flow of the water and air to the motor and hand piece is controlled by solenoid valves and adjusted by needle valves, refer to Figures 1.4-1 and 1.4-2. Vacuum is provided by the vacuum pump. The vacuum pump is connected to the waste container. The waste container is connected to the HVE and saliva ejector, refer to Figure 1.4-3. Operation of the unit is controlled from the control panel.

1.4.1 Electric Power Subsystem

The electric power subsystem provides power to the unit. It is composed of the power cord, power cord connector, main power switch, duplex outlet, circuit breakers, RF Filter, compressor/vacuum pump relay, power supply, voltage control circuit board, voltage control relays, 220VAC to 110VAC step down transformer, and associated connections and wiring, refer to Figures 1.4-6 and 1.4-7.

The system is designed to be capable of operation on any power from

100VAC to 240VAC, 50 or 60 Hz. The voltage control circuit board senses the input voltage and configures the power system according to the power it is connected to. The voltage control circuit board senses the voltage and then configures the voltage control relays to the proper configuration.

The duplex outlet allows for the connection and operation of additional accessories. It is switched through the power switch and has its own circuit breakers. It is connected to a step-down transformer for when the unit is connected to 200VAC or more.

NOTE

The duplex outlet will ALWAYS be approximately 110VAC. The voltage will vary depending on the mains voltage. The frequency will be THE SAME AS the mains power.

WARNING - Electrical and Fire hazard

If the frequency of the load and the duplex outlet are not the same it may cause heating of the load and step down transformer and may cause an electrical short or fire.

NOTE

The duplex outlet is rated for 100watts

The entire unit is protected by a 10-amp circuit breaker incorporated into the mains power circuit and the line and return of the duplex outlet are protected by 2A circuit breakers.

Electric power is provided to the compressor/vacuum pump through a logic activated relay. When the control button on the control panel is activated the relay closes and power is provided to the compressor/vacuum pump. The compressor also has a pressure limit shut-off. When the pressure in the air storage tank reaches approximately 60 PSI the control circuit board deactivates the relay turning the compressor/vacuum pump OFF. This also deactivates the normally open bleed solenoid valve bleeding the air from the compressor cylinder.

NOTE

The compressor will not restart with pressure in the compressor cylinder or vacuum in the vacuum line.

1.4.2 Electronic Control Subsystem

The electronic control subsystem powers and controls operation of the low voltage components, hand piece motor, fiber optics, cooling fan, relays, and solenoid valves, refer to Figure 1.4-7. It is composed of the control circuit board and control panel.

The control circuit board takes 36 VDC, 12 VDC, and 5 VDC from the power supply and provides 0 to 30 VDC to the motor, 12 VDC to the solenoid valves, compressor/vacuum pump relay, and fan, and 5 VDC to the fiber optics.

Control circuitry is incorporated into the circuit board to apply power to the solenoid valves and fiber optics only when they have been turned ON at the control panel and the motor is operating and to keep the fiber optics ON for approximately 20 seconds after the motor is turned OFF.

Motor controls include ON/OFF, Panel/Foot Switch, speed, and low cooling airflow. The Panel/Foot Switch switch is included to allow motor control in the event the foot switch fails. When in Panel mode motor speed can be controlled using the motor speed control buttons on the control panel.

The low cooling airflow sensor on the control circuit board senses when there is low cooling airflow to the motor, stops the motor and illuminates the red low cooling airflow LED on the control panel. The operator can restart the motor by pressing the motor speed increase button on the control panel once.

CAUTION

The motor requires cooling air. Motor damage may result if the motor is operated for extended periods without cooling airflow.

1.4.3 Air Supply Subsystem

The air supply subsystem provides compressed air to the unit for motor cooling air, chip air for the hand piece, and pressurization for the water supply subsystem. It is composed of an oilless air compressor, check valve, in-line water trap/filter, distribution manifold, pressure regulator, solenoid valves, flow control valve, air storage tank, external air valve, air/water syringe (this has been included in both the air and water subsystems), pressure gauge, pressure sensor, compressor bleed solenoid valve,and associated plumbing and fittings, refer to Figure 1.4-1

The air storage tank can be pressurized by either the internal compressor or an external compressed air source. The pressure gauge is used to monitor the pressure in the air storage tank.

Compressed air flows from the compressor through the water trap/filter and check valve to the air storage tank and pressure regulator. The regulator controls the air pressure to the motor, water reservoir, air/water syringe, and hand piece and is set at the factory to approximately 60 PSI. Airflow to the motor is controlled by a solenoid valve on the manifold. The solenoid valve opens whenever the motor is turned on. This is an automatic function. The motor airflow splits, going to the low cooling airflow sensor on the circuit board and to the motor through the motor cooling airflow control needle valve. The hand piece airflow is controlled by a solenoid valve on the manifold. The air flows through the solenoid valve and then through a flow control needle valve to the hand piece. When the air control on the control panel is ON the solenoid valve is opened when the motor turns on, allowing air to flow to the hand piece. Air is provided directly to the air/water syringe with the syringe controlling the ON/OFF flow.

A pressure relief valve is incorporated into the compressor outlet. The valve relieves the pressure at about 70 PSI when the suction is turned ON. This reduces the load on the compressor and the power draw.

There is also a compressor bleed solenoid valve connected to the outlet of the compressor. This is a normally OPEN valve that is closed by the control microprocessor on the main circuit board when compressed air is needed, that is the pressure is about 40 PSI or less. The valve opens when the compressor is turned OFF bleeding the air from the compressor outlet line. Note, the compressor WILL NOT restart with pressure in the outlet line.

1.4.4 Water Supply Subsystem

The water supply subsystem is an independent self-contained water system, which provides water to the air/water syringe and hand piece. It is composed of the water reservoir, filter, water solenoid valve, water flow control

valve, back flow check valve, air/water syringe, and associated plumbing and fittings, refer to Figure 1.4-2.

Compressed air pressurizes the water reservoir, which forces water through the filter. The flow splits between the air/water syringe and hand piece.

The hand piece flow goes through a solenoid valve and then through a flow control needle valve. When the hand piece water control on the control panel is

ON the solenoid valve is opened when the motor turns on, allowing water to flow to the hand piece. Water is provided directly to the air/water syringe with the syringe controlling the ON/OFF flow.

1.4.5 Vacuum Supply Subsystem

The vacuum supply subsystem is an independent self-contained vacuum system, which provides vacuum for the HVE and saliva ejector. It is composed of an oilless vacuum pump, waste container, solids trap, vacuum water trap, HVE, saliva ejector, vacuum shut-off valve, and associated plumbing and fittings, refer to Figure 1.4-3.

The HVE and saliva ejector tubes are attached to the top of the waste container. When the vacuum control on the control panel is turned ON the vacuum pump is activated and evacuates the waste container, drawing the waste fluids through the HVE and saliva ejector tubes into the waste container. The solids trap is located in the waste container.

The vacuum shut-off valve is integrated into the vacuum connector on the waste container top. It is a float type valve. When the fluids get to a certain level in the waste container a float ball will shut the vacuum off.

NOTE

It is possible for the vacuum shut-off valve to activate prematurely and/or stick if it has not been cleaned completely. To restore flow if the valve activates prematurely you must release the vacuum on the valve. To release the vacuum just turn the vacuum pump OFF and open the HVE valve, this will allow the valve to OPEN.

NOTE

If the vacuum pump is left ON and there is no operation of the hand piece motor for approximately 12 minutes the controller will turn the vacuum pump OFF and blink the Vacuum Pump ON and Compressor ON LEDs. To restore normal operation press any button on the Control Panel.

NOTE

In the event there is a sudden loss of suction with the HVE and saliva ejector check the fluid level in the waste container.

NOTE

The vacuum pump WILL NOT start with vacuum in the inlet line. In this situation the motor will make a humming sound when turned ON. To relieve the vacuum connect a vacuum tube or fitting to the vacuum connector on the back of the base unit, see page 29

NOTE

A thermal shut-off switch is integrated into the pump motor windings to shut the pump off if it gets too hot. To resume operation just let the pump cool down.
