9.6 Door Safety System for models 2540, 3150, 3850, 3870
The door opening is ensured by two means:
1. The closing device prevents an incidental opening of the door.
2. A pull-type solenoid, which is in inactivated position, locks the door
and must be electrically powered to release the locking and enable the
opening of the door.
9.6.1 Solenoid locking device
The solenoid locks the door in the following situations:
1. When the control unit is not powered.
2. If power failed or has been turned off while the autoclave
is in operation, even if power has been restored.
3. If operation was stopped before completion of the cycle as
a result of a failure or a manual stop.
4. When the temperature inside the autoclave chamber is
higher than the “end of cycle” temperature, preset by the
operator; the opening of the door is possible only when the
temperature has dropped below preset value.
For cases described at points 2 and 3, press the START/STOP
key to cancel the door locking at the end of the operation.
If, for any reason, the locking mechanism does not open, call for
Tuttnauer service.
Warning!
Do not use force to open the door
