Steri-Vac 8XL Gas Sterilizer/Aerator Service and Repair TROUBLESHOOTING AND REPAIR 3M 1997 April 47 Clear Silent Abort Clear Silent Abort is used to correct a Silent Abort error. This procedure is only used to clear specified errors and should not be performed unless directed by those error analysis procedures. DANGER Make sure static discharge wrist ground straps are worn when setting configuration switches or when working with the Steri-Vac 8XL Sterilizer covers removed. Static discharge will cause damage to equipment. Failure to wear static discharge straps can result in damage to equipment or injury to personnel. Note: Do not cycle power. 1. Set SW1 configuration switches 3 and 7 to the closed position (see Figure 28). 2. Set SW1 configuration switches 1, 2, 4-6, and 8 open (see Figure 28). During Clear Silent Abort the sterilizer automatically does the following: • Removes the error from the display and starts printing the report. • Punctures gas cartridge for one minute. • Runs a time based final vacuum for 18 minutes. • Opens the vent and purges for 30 minutes. • Closes the vent and locks up. • After Clear Silent Abort, the screen clears and the error is displayed. The report stops printing and the chamber parameters display. 3. If an error is still displayed after the gas is removed from the chamber, return to the error troubleshooting procedure to clear the error. 1 2 3 4 5 6 7 8 SW1 Dip Switch #s Clear Abort (System Reset Mode) Figure 28.

Service and Repair Steri-Vac 8XL Gas Sterilizer/Aerator TROUBLESHOOTING AND REPAIR 48 3M 2004 October Reset Site Setup Reset Site Setup is automatically performed by the sterilizer when an E1 or E2 checksum error occurs or when a new controller circuit board is installed. Reset Site Setup can be forced by the service representative for troubleshooting purposes or if one of the conditions previously mentioned did not automatically cause a reset to occur. Note: When a new controller board is installed and the sterilizer automatically performs a system reset, three long beeps will be heard when the sterilizer is powered up. This indicates the system parameters are set to their default settings. 1. Power Off the Steri-Vac 8XL Sterilizer. DANGER Make sure static discharge wrist ground straps are worn when setting configuration switches or when working with the Steri-Vac 8XL Sterilizer covers removed. Static discharge will cause damage to equipment. Failure to wear static discharge straps can result in damage to equipment or injury to personnel. 2. Set SW1 configuration switches 2 and 7 to the closed position (see Figure 29). 3. Set SW1 configuration switches 1, 3-6, and 8 open (see Figure 29). 4. Power On the sterilizer. 5.

Steri-Vac 8XL Gas Sterilizer/Aerator Service and Repair SPECIAL CYCLES 3M 1997 April 83 Emergency Aeration Emergency aeration is used to aerate a load that needs further aeration. This option can be activated by configuring SW1 DIP switches (see page 45) or from the Main menu during Normal Mode (the following procedure). DANGER Make sure all precautions pertaining to the handling, use, and storage of Ethylene Oxide (EO) are observed. See the Site Planning and Installation Guide and the Operator’s Manual for detailed information in the handling, use, and storage of EO. Refer to the Ethylene Oxide Safety information at the front of this manual for the effects of EO exposure. 1. Place the items requiring further aeration in the sterilizer chamber. 2. With the sterilizer in Normal Mode, use the temperature select softkey (1) to set the cycle temperature. Use the Up arrow and Down arrow softkeys (2, 3) to set the cycle time. 3. Close the sterilizer door. 4. Press the Stop button (4) twice (within one second) to display the operator’s Site Setup menu. 5. Using the Up and Down softkeys, highlight the EMGY AER on the Site Setup menu. 6. Press the Select softkey to toggle EMGY AER to ON. 7.

Service and Repair Steri-Vac 8XL Gas Sterilizer/Aerator SPECIAL CYCLES 84 3M 1997 April Accelerate Cycle This SW1 DIP switch controllable option allows the service representative to accelerate the time of selected stages of a cycle by 60 during a sterilization cycle, in the normal operating mode (1 hour will equal 1 minute). See table at right for specific elements of the cycle that are accelerated. The acceleration DIP switch can be actuated anytime during the sterilization cycle, usually before the cycle starts. If the DIP switch is set to accelerate during a cycle, the time for the current stage will not be accelerated. During a cycle, times are first calculated then the stages are performed. After a stage has started, the only way to accelerate that stage is to cycle the power. When the sterilization cycle restarts, the acceleration option is detected and the new time is calculated. If the accelerated option is changed to non-accelerated during an accelerated cycle, the accelerated time continues until the next stage starts. Notes: Do not consider items loaded in the sterilizer chamber during accelerated times sterilized. Accelerate Cycle is a Normal Mode service operation. The sterilizer must be set to operate or be operating in the Normal Mode to activate this option. DANGER Make sure static discharge wrist ground straps are worn when setting configuration switches or when working with the Steri-Vac 8XL Sterilizer covers removed. Static discharge will cause damage to equipment. Failure to wear static discharge straps can result in damage to equipment or injury to personnel. 1. Make sure the sterilizer is in Normal Mode. 2. Close SW1 configuration switch 2 (see Figure 30). 3. If no additional cycles are to be run with accelerated time, set SW1 configuration switch 2 to open.

Steri-Vac 8XL Gas Sterilizer/Aerator Service and Repair SPECIAL CYCLES 3M 1997 April 85 Simulating Low Pressure This SW1 DIP switch controllable option allows the service representative to simulate most pressure related checks during a normal sterilization cycle (see table at right for specific elements of the cycle that are simulated). Note: Do not consider items loaded in the sterilizer chamber during simulated pressure cycles sterilized. The simulated pressure DIP switch can be closed anytime during the cycle; usually the switch is closed before the cycle starts. If the DIP switch is set to simulate low pressure during a cycle, the pressure for the current stage may not be simulated. DANGER Make sure static discharge wrist ground straps are worn when setting configuration switches or when working with the Steri-Vac 8XL Sterilizer covers removed. Static discharge will cause damage to equipment. Failure to wear static discharge straps can result in damage to equipment or injury to personnel. Note: Simulating Low Pressure is a Normal Mode service operation. The sterilizer must be set to operate or be operating in the Normal Mode to activate this option. 1. Make sure the sterilizer is in Normal Mode. 2. Close SW1 configuration switch 1 (see Figure 31). All low-pressure stages are simulated during the sterilization cycle. 3. If no additional cycles are to be run with simulated low pressure, set SW1 configuration switch 1 to open.

CAUTION Only the 37°C, 180-minute and the 55°C, 60-minute cycles are approved for hospital use in the US. Additional cycles must be validated by the end user to meet FDA requirements. Use of unapproved cycles can result in inadequate sterilization. Note: Only the 37°C, 180-minute and 55°C, 60-minute cycles are active after Defaulting System. 1. The temperature and gas cycles and times are set through the SET CYCLES option of the Misc. Service menu. If the sterilizer is not at the Misc. Service menu perform the necessary steps from the following to display the Misc. Service menu: a. Place the sterilizer in the Service Mode - page 9. b. Place the sterilizer in Site Setup - page 11. c. Place the sterilizer in Misc. Service - page 23. 2. Using the Up and Down softkeys, highlight the SET CYCLES option on the Misc. Service menu. 3. Press the Select softkey. 4. Using the Up and Down softkeys, highlight the desired temperature cycle. Notes: A small circle (o ) to the left of the listed temperatures indicates that temperature cycle is selected. A one (1) indicates the temperature is not selected. Selecting temperature with a 1 next to it de-selects that temperature and it will not display on the Misc. Service menu. At least one of the Cycle Temps must be selected. 5. Press the Select softkey.
