CODE PHASE DESCRIPTION
Vacuum test: leak during
maintenance phase.
Vacuum
E34
Rate of leak :::::::::
test
If ∆P/∆t = p3-p2/10 ≥ 13
mbar.
Vacuum test: temperature
outside set range.
This occurs if the internal
temperature probe detects
Vacuum
E35
a temperature ± 3°C higher
test
than the initial temperature
Internal boiler temperature
sensor not working if the
E41
2-17
PTC1 sensor measures a
full-scale value
External boiler temperature
sensor not working if the
E42
2-17
PTC2 sensor measures a
full-scale value
Generator temperature
sensor not working if the
E43
2-17
PTC3 sensor measures a
full-scale value
Cooling system
temperature sensor not
E44
2-17
working if the PTC4 sensor
measures a full-scale value
Ambient temperature
sensor not working if the
E45
2-17
PTC5 sensor measures a
full-scale value
Pressure sensor not
working if the PS1 pressure
E46
2-17 transducer measures a full-
scale value
Sensor for detecting closed
door not working if the
SW1 micro-switch fails to
E47
2-17
detect the closed door
during the sterilization
cycle.
Sensor for detecting door
safety not working if the
SW2 micro-switch fails to
detect the door safety lock
E48
2-17
during the sterilization
cycle.
POSSIBLE REASON
Leak from hydraulic circuit
1 Irregular heating during
test due to a sudden
change in temperature if
the unit was stored at
temperatures.
2 PTC1 temperature probe
faulty, though neither in an
open nor a closed circuit.
PTC1 probe faulty: circuit
open, short circuit or false
contacts
PTC2 probe faulty: circuit
open, short circuit or false
contacts
PTC3 probe faulty: circuit
open, short circuit or false
contacts
PTC4 probe faulty: circuit
open, short circuit or false
contacts
PTC5 probe faulty: circuit
open, short circuit or false
contacts
Sensor faulty
1 False contact between
cables or flat cable
disconnected.
2 SW1 micro-switch faulty.
1 False contact between
cables or flat cable
disconnected.
2 SW2 micro-switch faulty.

AUTOCLAVE
ACTION
Check the tubes, unions,
porthole and solenoid
valves for leaks.
1 Turn off the unit, wait for
it to adjust to ambient
temperature and then
repeat the test.
2 Check probe operation
and replace if necessary
1 Check contacts with
card.
2 Replace the PTC1
probe.
1 Check contacts with
card.
2 Replace the PTC2
probe.
1 Check contacts with
card.
2 Replace the PTC3
probe.
1 Check contacts with
card.
2 Replace the PTC4
probe.
Replace the display card.
Replace sensor and check
contacts with card.
1 Check micro-switch
connections.
2 Check and/or replace
micro-switch.
1 Check micro-switch
connections.
2 Make sure the
electromagnet comes
out upon start-up.
3 Check and/or replace
micro-switch SW2.
