Installation Site 1. Install the autoclave according to the following guidelines: 2. Place the autoclave on the floor. Verify that the surface is leveled. 3. All utility supplies must be prepared in accordance with requirements, before autoclave installation e.g. mineral-free and tap water, compressed air, one or three-phase power network, connection to the drain of the building.
TESTS Installation Tests The service technician shall perform the following preliminary checks before operating the autoclave: Integrity Check Perform a visual check to verify that there are no dents, scratches, broken gauges, etc. Leveling Check Check that the autoclave is leveled. Leakage current test Check the precise operation of the earth leakage relay.
WATER QUALITY Water for Generating Steam The distilled or mineral – free water supplied to the sterilizer shall be according to the table below: Physical Characteristics and Maximum acceptable contaminants levels in steam for sterilizers (According to EN 13060:2004). Element Condensate –...
DESCRIPTION OF THE CONTROL SYSTEM. (See CDR Control diagram). The control system is based on 3 electronic boards designed according to the autoclave requirements, the digital board DIG-T2 containing the micro-controller memories, buffers and digital ICs and the analog board ANL-T2 which performs the processing of signals coming from the sensors and switches.
This component is optimal because it is related to the operation of the printer, which is also an optional item. — The board contains a watchdog, which detects any faulty situation in the running program code. It performs an automatic reset of the micro- controller and stops all the commands to avoid an uncontrolled activation of any of the heating elements or the valves.
Analog Board ANL-T2 The analog board contains the drivers of the valves, heaters and pump. It contains the sensors circuits connected to the control system, and serves as a junction to the autoclave connections. The input is 12VDC & 5VDC and the output is for all the signals to the autoclave.
AC - Board - AC-T1 This board receives command signals from ANL-T2 board designated to activate AC devices. It converts them to AC mode. The AC-T1 board provides AC filtering for the power supply to the control system and protection from sharp current fluctuations. The AC-T1 board includes: —...
CALIBRATION OF TEMPERATURE AND PRESSURE Method of Calibration: The calibration of temperature and pressure is performed digitally. The temperature and pressure measuring circuits are designed with components having 1% accuracy. The temperature circuit is linear and has an output of 100mV÷2400mV for a temperature range 20°C÷150°C.
Temperature Calibration Procedure — Press the PROGRAM key. — The system enables to set the system’s date the time. — This operation is skipped by pressing PROGRAM key six times. — CODE: will be displayed. — Select Technician Code (011) by the UP/DN keys and press the PROGRAM key.

SOFTWARE PROGRAMMING PROCEDURES General The software for the control system of laboratory autoclaves is constructed as one software for all types of laboratory autoclaves (table and vertical), version LAB00VN1. The software contains a table of parameters of which part of them defines the autoclave, and part defines the processes in the autoclave.

9.2.22 Factor This sets the air pressure in the chamber during sterilization and cooling in the Hot Water method. For example: if the temperature in the chamber is 121º C, and the suitable steam pressure is 205kPa, if the selected factor is 1.5, the pressure that will be kept in the chamber will be 205 x 1.5 = 307.5kPa.
9.2.25 DryPulss If the system contains a vacuum pump (i.e. the Vac Pump parameter = 1), and a dry stage is required, the air valve will open or close according to the value of DryPulss. If DryPulss = 0, the air valve remains closed. If DryPulss = 1, after 4 minutes of evacuating the chamber during the dry Stage, the air valve will open in shoot mode of 10 seconds on and 50 seconds off.
REPLACING ELEMENTS 10.1 Safety Tests after Repair ATTENTION! After every repair or dismantling the enclosure, the autoclave should pass two safety electrical test by the Service Engineer. The following shall be performed: 1. Enclosure Leakage Current Test. Every autoclave should pass this test as follows: 1.
ASME type safety valves. 1. Open the right door. 2. Disconnect the pipe connection. 3. Unscrew the safety valve (including the base For models 2540, 3150, 3170, 3850, 3870 or elbow for models 5050, 5075) and remove from the autoclave.

10.7 Cut-Out Thermostat Warning: Before starting, disconnect the instrument from the power source and ensure that there is no pressure in the autoclave chamber. This thermostat cuts out the power to the autoclave, in the event that all other safety systems malfunction. For example: if the autoclave operates without water in the chamber, the PT100 detect this and the control unit cuts the electricity to the heaters.
9. After replacing the heating element run a cycle and verify that it operates as required and that there is no leakage. 10. Close the autoclave’s service door. 11. Test the autoclave by performing a full cycle. 3150/317 3850/387 5050/507 Description 2540 HEA012- HEA012- HEA012- HEA012- Heating element 0005 0006...
