2. Using a sample coil
-
Switch off the sterilizer using the
main switch 13
and disconnect the
temperature probe
PT1 39
(connector CN12 on the
power board 34
).
-
Connect a sample coil with an R value from 1000 to 1573 Ohm, corresponding to a
temperature (°C) of
T = (-R0*A+(R0^2*A^2-4*R0^2*B+4*R0*R*B)^0,5)/2/R0/B
where
R0 = value of the
temperature probe PT1 39
at 0°C (written on label and set in PT1 probe
calibration in the Technician Menu)
A = 0,0039083
B = -0,0000005775
-
Switch on the sterilizer and check the temperature value which appears on the display.
- Adjust the temperature using the Correction parameter in the Technician Menu (option
10).
3. Replacing the temperature probe PT1
-
Replace the
temperature probe PT1 39
.
-
Select option 3 in the Technician Menu (Board calibration PT1) and proceed with
calibration.
-
Select option 7 in the Technician Menu (Probe calibration PT1) and enter the R0 value.
Adjusting pressure setting
To adjust pressure setting select option 6 from the
Technician Menu (Board calibration TP)
and follow the instructions.
Replace the transducer if the error between the pressure shown on the display and the
pressure indicated by an external calibration tool exceeds ±50 mbar.
•
If the alarm is not resolved, possible causes can be:
-
sudden leakage from a valve or a disconnected pipe;
-
faulty
temperature probe PT1 39
;
-
faulty pressure
transducer 38
;
-
faulty electronic board.
Level probe alarm
This alarm indicates inconsistent operation of the level probes in the
clean water tank 10
.
For example, if the maximum level probe detects presence of liquid, minimum level probe
and tank safety probe should also detect it.
The sterilizer shows this message in STAND BY mode.
•
Empty, clean and fill the
clean water tank 10
. The operation must be performed at
environmental temperature.
•
Check the level probes.
•
Replace the level probe insulation.
•
Check water quality. Excessively pure water is corrosive (it removes salts from metals)
and cannot be detected by the probes.
In particular, DO NOT use bidistilled water or
water with a conductivity of less than 1 µS/cm.
