7. CALIBRATION OF TEMPERATURE AND PRESSURE7.1 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.The pressure circuit is also linear and has an output of 100mV÷2400mV for a pressure range 0÷400 kPa.The measuring at the A/D is limited for values higher than 2400mV or below 100mV.It is obvious that although the accuracy of the circuit components is 1%, the sum deviation may reach 5%. Therefore calibration is necessary. The system has a non-volatile memory in which the offset and gain data of the sensors are stored. Calibration is performed by use of the keyboard (or the communication port for computer use).Following is a description of the calibration of temperature and pressure using the keyboard. The calibration procedure is identical to all autoclave models.

Definition of Gain and Offset:Every straight line can be defined by the equation ax+b=y. “a” is the deviation from y=0 and “b” is the slope of the line. In our case a=Gain and b=Offset.

The system is based on calculation of offset and gain of two points as in the following exampleIf the actual measured pressures are 100 kPa & 300 kPa and the displayed pressure are 90 kPa & 310 kPa respectively, the ‘input Vs pressure” graph will be as follows.

The calibration method enables to input this data into the system in order to perform automatic correction of OFFSET and GAIN.It is necessary to define the two points, which have to be input to the system, prior to performing calibration.

7.2 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.

— Select CALIB CODE: 107 to calibrate the system by means of the UP/DN keys and press the PROGRAM key again until TEMP CAL: will be displayed.

— Set calibration code to TEMP CAL: 1

— Press the PROGRAM key again and do not change the code.

— The following data will be displayed:

UPPER ROW: A 60.0 R 60.0

LOWER ROW: A 130.0 R130.0

Enter the actual data (A) and the displayed data (R) for two known points as in the following example:The actual temperatures are 70°C & 120°C and the displayed temperatures are 68°C & 120°C respectively. the Proceed as follows:— On the upper row, change A60.0 to A 70.0 by means of UP/DN keys.


— The cursor on the upper row will move to R60.0, change to R68.0 by means of UP/DN keys.


— The cursor moves to the lower row to A 130.0, change it to A 120.0 by means of UP/DN keys.


— The cursor on the lower row will move to R130.0, change to R123.0 by means of keys UP/DN, then press the PROGRAM key

This completes calibration procedure for temperature.

of 132 Pages

Remarks: — When cursor is set under any figure, pressing the START/STOP key stops

calibration.

— When the cursor is set under any figure, it enables to feed this value to the reading of temperature by pressing the PARAMETERS key.

Example: If the cursor is set under R68.0 on the upper row and the actual temperature of the autoclave is now 66.0ºC, by pressing the PARAMETERS key, the temperature reading will be corrected from R68.0 to R 66.0.

This calibration method enables the technician to change a certain point without affecting a second point.

Example:When the working temperatures are 134ºC and 121ºC but the actual temperature are 132ºC and 121ºC The measured temperature for 134ºC must be corrected without changing the temperature at 121ºC, Considering the above example, the setting of data can be done as follows:

A 121.0 R 121.0A 132.0 R 134.0

The system will calibrate the new offset and gain and retain them into the non-erasable memory. As a result, while running a 134ºC program the correction is automatically made, while at 121ºC no change is felt.

— Press the PROGRAM key, the cursor will move to R 100.

— Press the PARAMETERS key. The system performs reading

pressure and displays it instead of R100. E.g. R97 (i.e. the system reads out 97kPa, when the door is open).


— The cursor moves to the lower row to A300.

If the system reads out 280kPa, do not change A300. Press the PROGRAM key to move to R300 and change it to the actual

pressure value 280kPa by means of the keys UP/DN.

— Press the PROGRAM key again.

The system calculates the new values for offset and gain and stores these values in the non-volatile memory.

This completes the calibration procedure for the pressure.

10.9 Safety Door Locking System for models 2540, 3150, 3170, 3850, 3870Door locking is achieved by means of two safety devices, a pull type solenoid which must be powered to enable the opening of the door and a pressure -activated door locking.

10.9.1 Solenoid Locking Device The solenoid locks the door in the following situations:When the control unit is not powered.a. If power failed or has been turned off while the autoclave is in

operation, even if power has been restored.

b. If operation was stopped before completion of the cycle as a result of a failure or a manual stop.

c. When the temperature inside the autoclave chamber is higher than the end of the cycle temperature, preset by the operator; the opening of the door is possible only when the temperature has dropped below the pre-set value.

The release of the door locking is done automatically at the completion of a normal cycle. In case of failure or manual stop, release the door locking by pressing the STOP key.

10.9.2 Replacing the Solenoid Locking DeviceCaution!Before starting, disconnect the instrument from the power source and ensure that there is no pressure in the autoclave.

For description of the locking device see next page.

1. Remove the door cover.

2. Disconnect the wires from the connector.

3. Unscrew the tightening nut (cat. No. CMT201-0004).

4. Remove the pin, the spring and the solenoid.

5. Replace the damaged items and reinstall according to drawing below.

6. Operate the autoclave and verify that the pin is retracted when the cycle reaches “stand-by” stage.

10.9.3 Emergency Door Opening In order to facilitate the initial installation, the door locking position is taped in this retracted position at the factory. On completion of all installation activities this tape must be removed. If for any reason the door locking mechanism is permanently locked, it is possible to open the door and provide access for eventual repairs to the locking mechanism. The swing bolt has a drilled opening located in the lock catch. By pushing the piston back with a 2mm. pin, the swing bolt may be turned another 3/4 turn until the position catches again. Repeat these operations until the bolt can be swung away and the door opened.

10.10 Safety Door Locking System for models 5050, 5075

To release the door locking to cancel the door locking at the end of operation; press the UP key

An additional door safety device is fitted to the models, 5050, 5075, which work with a central closing mechanism. This device is a piston-cylinder assembly valve, activated by one of the radial locking arms and connecting the chamber to the open atmosphere, through a small nozzle. When the first step of opening the door is performed and arms are unlocked turning the handle counter-clockwise, the arms change direction, the piston is released and valve opens, chamber is aerated and residual pressure discharged from the chamber.

Following this, opening the door by pulling it, can be done safely, with no risk for the operator, of steam or hot water burst.

Two microswitches ensure that operation cannot be started if autoclave door is unlocked; one is activated by the door, when it is lowered down to the frame, the second by one of the arms in position locked. When the two micro-switches are pressed, the light “DOOR” on the keyboard panel is OFF and operation can be initiated.
