THEORY OF OPERATION
The Game Ready System allows the user to adjust treatment time, temperature and air
pressure as desired. Both Manual and “Program Modes” are offered for convenience. The
Control Unit comprises a user interface “Control Panel”, a microprocessor, multiple sensors,
Hose connection port, and a 12VDC power inlet. The following sections offer additional insight
as to how the Control Unit works.
2.1.
Self-Diagnostics Checks
When pressing the power button, the Control Unit performs several Self Diagnostic
checks.
2.1.1.
LCD Display
All segments of the LCD display are cycled on and then off during the self-test. This allows
the user to inspect the segments for function.
2.1.2.
Air Pressure Sensor “Zero” Check
With the air pump off and the solenoid valve open, the air pressure transducer is checked
for an acceptable range (should be close to atmospheric pressure, or zero pressure). If
the pressure is beyond acceptable limits, an “01 error” will occur. This could be caused by
a bad pressure sensor, or if the Control Unit is hooked up to a Wrap still containing air
pressure.
2.1.3.
Air Pump Check
If the Air Pressure Sensor “Zero” Check passes, the solenoid valve is closed and the air
pump turned on. If the air pressure is not greater than zero within ½ a second, an “02
error” will occur. After this test the air vent is opened and the air pump turned off.
