1.3 Description of Normal Operation
(Figure 1-3 shows Display Panel Buttons & Lamps)
(Figure 1-4 shows location of Major Components)
Plug Power Cord Into Outlet
Display: E001 (Error lamp flashes)
1. Line voltage (100/115/230V) is supplied to Control
PC Board.
NOTE
There are two primary fuses on PC Board. Faulty
fuse(s) will disable all functions of sterilizer.
Press ON/STANDBY Button
Display: (Error lamp goes out; ON/STANDBY lamp
illuminates, & program lamps flash)
Select Cycle (Unwrapped, Pouches, Liquids, Packs)
Display: TIME/TEMP. (for the selected cycle)
Press START Button
NOTE
After the START button is pressed, the PC board
continuously monitors the Door Switch for continuity.
If continuity is not detected, the PC board stops the
cycle, and the Door Ajar lamp illuminates.
1. The Fill Cycle is initiated.
Fill Cycle
Display: (Filling lamp illuminates)
1. Line voltage from PC Board energizes Fill Solenoid;
this allows water to flow into Pressure Vessel.
2. Water fills Pressure Vessel until it makes contact
with the Pressure Vessel Water Level Sensor.
3. When water completes the ground circuit between
the Pressure Vessel Water Level Sensor & the
chassis, the PC Board de-engergizes the Fill
Solenoid & the Steriliation Cycle is initiated.
Sterilization Cycle
Display: (Sterilizing lamp illuminates)
xxx° (chamber temperature)
xx PSI [after temperature reaches 208°F (98°C)]
NOTE
During the Sterilization Cycle, the Temperature Probe
monitors the chamber temperature and the PC Board
monitors chamber pressure.
