Outputs
The status of the steriliser outputs can be displayed and modified:
• EV1 charge to which the water inlet pump 35 is connected in parallel
(included on all models)
• EV2 drain (included on all models)
• EV3 3-way (not included on 6/18 S Dynamica models)
• EV4 steam (not included)
• EV5 drying (not included on 6/18 S Dynamica models)
• EV6 by-pass (not included on 6/18 S Dynamica models)
• Water pump is the automatic water inlet pump 46 (optional; standard on
BHD models). If the steriliser is provided with connections to the SPEEDY
WATER demineralisation system, the pump is replaced by solenoid valve EV7
(see page 51)
• Vacuum pump (not included on 6/18 S Dynamica models)
• Door lock (included on all models)
• The fan(s) are fans 42: single on 6/18 S Dynamica and 18 S; double on other
models
• Aux 1 is not used
• Aux 2 is not used
• External coil for pre-heating and drying chamber 09
• Internal coil for steam generation
NB. The internal coil is:
• The external cylindrical band arranged around chamber 09 in models 18 S
Dynamica, 18/24 S - B - BHD
• The series of lower and upper coils external to chamber 09 in 6 S Dynamica
The internal coil is:
• The coil in chamber 09 in models 18 S Dynamica, 18/24 S - B - BHD
• The lower coil external to chamber 09 in 6 S Dynamica
Use the ↑↓ arrows to scroll the list and highlight the required option. Press ENTER to change
the output state (ON/OFF).

PT1 / PT2 / PT3 board calibration
This procedure is used to calibrate temperature probe PT1, PT2 and PT3. A specific
calibration kit is needed for calibration:
To calibrate PT1, PT2 or PT3 press option 3, 4 or 5 respectively in the Technician Menu:
CN2
CN1
CN3
CN4 0-5V switch
Technician Menu

16
Disconnect the connector corresponding to the temperature probe you want to calibrate
from the electronic power board 34: disconnect connector CN12 for sensor PT1,
connector CN13 for sensor PT2 or connector CN14 for sensor PT3.
Using the cable included in the kit, connect connector CN1 of the calibration tool (which
corresponds to a 1000 Ohm sample coil, corresponding to 0°C) to connector CN12, CN13
or CN14 of the power board 34:
Wait for at least 10 seconds and press ENTER.
Technician Menu

17
Disconnect the cable from connector CN1 of the calibration tool and connect connector
CN2 of the calibration tool (1573 Ohm sample coil, corresponding to 150°C) to calibrate
the sensor PT1 or the connector CN3 (1832 Ohm sample coil, corresponding to 220°C) to
calibrate sensors PT2 and PT3.
Wait for at least 10 seconds and press ENTER.
Press to go back to the Technician Menu without changing the calibration.

TP board calibration
This procedure is used to calibrate the pressure transducer:
Disconnect the connector CN11 corresponding to the pressure transducer from the
electronic power board 34:
Technician Menu

19
Using the cable included in the kit, connect connector CN4 of the calibration tool to
connector CN11 of the power board 34.
Set the calibration tool switch to 0 Vdc.
Wait for at least 10 seconds and press ENTER.
Now set the calibration tool switch to 5 Vdc.
Wait for at least 10 seconds and press ENTER.
Press to go back to the Technician Menu without changing the calibration.

PT1 / PT2 / PT3 probe calibration
This procedure is used to complete the calibration of the temperature probes PT1, PT2 and
PT3. This operation must be performed whenever a temperature probe is replaced.
Press +/- to enter a 0°C value of the temperature probe shown on the label or on the wire
sheath (e.g.: if a value of 1000.2 is shown on the PT1 sensor label, press + twice to display
1000.2). Press ENTER to confirm.
Press to go back to the Technician Menu without changing the calibration.
PT1 / PT2 / PT3 correction
This procedure is used to correct the temperature value displayed during the sterilising
process. For example, if using an external sampling tool a temperature lower than the one
displayed is measured in the chamber during the sterilisation process, the temperature
may be corrected as follows:
Press +/- to enter the correction which will change the temperature shown on the display.
Press ENTER to confirm.
Press to go back to the Technician Menu without changing the correction.
