Cascade Master Series Overview
The Cascade Master Series option consists of five components, which control standard chair and delivery system functions. These components include: master touchpad, master 17-watt power supply, master circuit board, solenoid valve manifolds, and master dental light air-electric switches. This section presents details on how to service the components and troubleshoot specific problems.

Master Touchpads
Master 17-Watt Power Supply
Master Circuit Board
This overview provides a brief description of each of the five master series components.
The master touchpad controls low voltage electrical signals that activate chair functions in the same manner as the standard chair touchpad. It also sends low voltage electrical signals to a bank of solenoid valves, which control the air pilot signals used to activate various delivery system functions, the dental light, and, optionally cuspidor functions.
The master 17-watt power supply connects directly to the power mains and provides power to the master circuit board.
The master circuit board receives electrical signals from the master touchpad to activate or deactivate a desired function. It then sends a low voltage electronic signal to the appropriate solenoid valve, opening or closing it to control air flow to the balance of the delivery system.

Cascade Master Series Components
Solenoid Valve Manifolds
Master Dental Light Air Electric Switches
The solenoid valve manifolds can contain a maximum of six normally closed solenoids, which control the pilot air signals used to activate standard Cascade unit and cuspidor functions. Each solenoid valve receives an electrical signal from the master circuit board, which causes it to open (no signal causes the solenoid to close). Each of the solenoid valves have an indicator that lights when the valve receives an electrical signal from the master circuit board. This signal causes the valve to open or close thereby controlling the flow of the pilot air signal through the valve.
The master dental light air-electric switch is connected in the common return for the light. It receives a pilot air signal from the solenoid valve manifold. This signal closes the normally open switch, which completes the electrical circuit, allowing the dental lamp to light.

Cascade Master Series Master Touchpad Functions
Air, water and electrical power to the handpiece control system, and dental light are turned ON or OFF when this button is pressed. An electrical signal is sent from the touchpad to the circuit board, which opens the master air solenoid valve, allowing the pilot air to activate the system.
Water coolant to the handpieces is turned ON or OFF when this button is pressed. An electrical signal is sent from the touchpad to the circuit board, which opens the water coolant signal solenoid, allowing the water coolant signal air to flow to the handpiece control block. This opens the water valve when the foot control is pressed. Handpiece coolant water can then be adjusted in the normal manner.
When the master On/Off, Air Coolant On/Off, and Water Coolant On/Off buttons are pressed, the indicator above the individual function switch (on the master touchpad) illuminates to indicate the function is ON.
Air coolant to the handpieces is turned ON or OFF when the button is pressed. An electrical signal is sent from the touchpad to the circuit board which, opens the air coolant signal solenoid, allowing the air coolant to flow to the handpiece control block. Handpiece air coolant can then be adjusted. Refer to Handpiece Controls (HC) for adjustment instructions.

Cascade Master Series Master Touchpad Functions
The Cascade master touchpad chair controls are identical to the standard A-dec chair touchpad. Refer to the Chairs (CH) section for chair programming instructions.
The cuspidor cup fill function may be accomplished by pressing the manual button on the top of the cuspidor or by pressing the touchpad button. An electrical signal is sent from the touchpad to the circuit board, which opens the cup fill signal valve, allowing the pilot air signal to flow to the cup fill circuit in the cuspidor. Cup fill functions may then be adjusted. Refer to Post Boxes & Cuspidors (PB) for adjustment instructions.
The cuspidor bowl rinse function may be accomplished by pressing the manual button on the top of the cuspidor or by pressing the touchpad button. An electrical signal is sent from the touchpad to the circuit board, which opens the bowl rinse signal valve, allowing the pilot air signal to flow to the bowl rinse circuit in the cuspidor. Bowl rinse functions may then be adjusted in the normal manner.

The dental light is turned ON or OFF when this button is pressed. An electrical signal is sent from the touchpad to the circuit board, which opens the dental light solenoid. Air from the solenoid closes the dental light air-electric switch, turning the light ON. Light intensity and other adjustments are the same as A-dec dental lights. Refer to Dental Lights (LI) for adjustment instructions.

Cascade Master Series Service
Servicing the Unit
Opening a Solenoid
Before servicing the unit:
Ensure that a minimum of 60 psi of air is being supplied to the unit. The indicators on the individual solenoid valves will light when air pressure is above 30 psi. The unit will not function unless the air pressure is above 60 psi.
Ensure that the unit is ON. The indicator above the button should be illuminated when the unit is ON. If the indicator is not illuminated, press the master On/Off button.
To manually open a solenoid, carefully turn the solenoid valve's manual override selector (orange) a quarter turn clockwise, to the ON (1) position. Do not force the override On/Off selector beyond the ON (1) position.
When a solenoid is manually opened, the indicator will not illuminate. The function will remain ON until the unit is turned OFF or the manual override selector has been returned to the OFF (0) position.
CAUTION
Use minimal force when manually opening a solenoid. Excessive force, or turning the override selector too far, will permanently damage the solenoid.
