retracted from the circular frame due to the rotary
movement of the arm holder to a position which is
described in dotted lines.
9.2.2 Safety means
The door is equipped with three safety means as follows:
9.2.2.1 Locking solenoid (7)
This solenoid is a “Normally pushed” pin type and is
located on an adjustable base (8). The solenoid’s pin is
spring loaded in such a way that when it is not
activated, the pin is pushed out.
A bracket with a hole is attached on the arm holder.
The hole is located in such a way that the solenoid pin,
when pushed, will be trapped in the hole.
An inclined tongue is welded to the bracket. This
tongue assists the pin to retract when the locking
mechanism is turned to the “unlocked position”. When
the pin is in the “locking position” it prevents the arm
holder from any angular movement.
9.2.2.2 Safety locking microswitch (10)
This microswitch is activated when the arms are in a
radial – “locked” position.
The microswitch signal one of the following:
a. Arms are locked – cycle can be activated
b. Arms are in a non-locked position
. It is possible to
start a cycle and the door can be opened.
9.2.2.3 DOOR CLOSED microswitch (13)
This microswitch is located under the circular frame (1)
and has an activating rod piercing through the frame.
When the door is closed it presses the micro-switch’s
rod. At this stage the microswitch sends a signal that the
door is closed.
The two micro-switches (10 and 13) ensure that
operation cannot be started if autoclave door is
unlocked. When the two micro-switches are activated,
the light “Door Closed” on the keyboard panel is ON and
operation can be initiated.
