M9/M11 Sterilizer Drying Mode Theory of Operation
To prevent risk of shock always disconnect power before removing covers or performing any service procedure.
Some procedures require power to be connected with covers removed. Line voltage is present. Use extreme caution to prevent electric shock.
The illustrations show only the components that affect the Drying Mode. Refer to the following dropdowns for detailed descriptions of the Drying Mode.

During the Drying Mode, the heating element is energized to dry the instruments in the chamber.
All electrical current is supplied thru the two high-limit thermostats on bottom of chamber. Refer to: Power Up Mode for further detail.
Display Panel
During the Drying Mode, the display panel will show:
Heating Element
During the Drying Mode, line voltage is supplied to the heating element at preset intervals to turn it ON / OFF. This continues for the duration of the Drying Mode.
When the drying time expires, voltage is removed from the high-limit thermostats and the heating element.
Temperature Sensor
The temperature sensor inside chamber monitors the temperature throughout the Drying Mode. In general, the temperature range will be approximately 170°F (77°C) to 200°F (93°C).
If the temperature exceeds 240°F (115°C), the PC board stops the current flow to the heating element until the temperature drops.
Sterilizer Door
The sterilizer door must remain open throughout the Drying Mode. If the door is closed, pressure may build up in the chamber resulting in an error code.

Display Panel
During the Drying Mode, the display panel will show:
Heating Element
During the Drying Mode, line voltage is supplied to the heating element at pre-set intervals to turn it ON / OFF. This continues for the duration of the Drying Mode.
When the drying time expires, voltage is removed from the high-limit thermostats and the heating element.
Temperature Sensor
The temperature sensor inside chamber monitors the temperature throughout the Drying Mode. In general, the temperature range will be approximately 170°F (77°C) to 200°F (93°C).
If the temperature exceeds 230°F (110°C), the PC board stops the current flow to the heating element until the temperature drops.
Sterilizer Door
The sterilizer door must remain open throughout the Drying Mode. If the door is closed, pressure may build up in the chamber resulting in an error code.
