a.
At the end of the circular movement of the
arms holder, the pin of the locking solenoid
slides to its locking position.
b.
When the arms moves the last radial
15 mm, one arm activate the microswitch,
while another arm (on which there is the
angular bracket) pushes the piston of the 3/2
valve to a position that the venting port of the
door is blocked.
2.
The user start a sterilization cycle by pressing a “
start
” key
on the operating panel.
3. Cycle completion.
There are 6 sterilization programs:
a.
Program 1 and 2 will end if the cycle is
completed and the pressure in the chamber is
below 115 kPa (abs).
b.
Programs 3 to 6 will end if the cycle is
completed, the pressure decreases below 115
kPa (abs) and the chamber temperature
decreases below 90
C.
4. After all completion conditions are fulfilled, the operator
must rotate the handle a little bit counterclockwise to
activate the microswitch (10).
Activating the microswitch will cause the “door”
light to flash a few times.
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.
This way, the second step, opening the door by
pulling it, can be done safely, with no risk for the
operator, of steam or hot water burst.
After the ”door light” had signaled the operator will
press the “up” key and the solenoid will retract.
At this stage the unlocking operation is completed
and the operator can open the door.
