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.

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.
