    element, temperature sensor assembly, condensingtank water level sensor (early M9 units only), pressurevessel water level sensor, pulse solenoid, thermostat,door switch, control PC board, fill solenoid, vent sole-noid, bellows assembly, display PC board, and apressure relief valve.

    B. Theory of Operation (See Figures 5-1 and 5-2).

    Theory Of Operation:

    Power is supplied to the control PC board when thesterilizer is plugged in. At this time, the control PCboard will flash the error lamp and display E 001. Thisis normal and occurs when the sterilizer is first pluggedin or if a power outage has occurred.

    When the ON/STANDBY switch is pressed, the errorlamp extinguishes and the program switches areenabled. The program lamps flash and the ON/STANDBY indicator lamp illuminates.

    The operator determines the desired cycle and selectsthe cycle by pressing either: UNWRAPPED,POUCHES, LIQUIDS, OR PACKS button. Uponselecting the desired cycle, the control PC board setsthe specific time and temperature parameters for thatcycle into memory. These settings are alternatelydisplayed on the TIME/TEMP display. Note: Thecontrol PC board will continue to use the same param-eters on subsequent cycles until a new type of cycle isselected.

    The operator presses the START button which signalsthe control PC board to initiate the cycle.

    The control PC board continuously monitors for an opendoor condition from the time the START button ispressed until the start of the drying cycle. It does thisby monitoring the door switch for continuity. If nocontinuity is detected after a cycle has been started, thecontrol PC board will stop the cycle and illuminate theDOOR AJAR indicator. The DOOR AJAR indicator willcontinue to flash until continuity is sensed or until theSTOP or ON/STANDBY button is pressed. Or, if thedoor is closed and continuity is sensed, the control PCboard continues the cycle.
