3.3.3 D-23
Principle
The devices are equipped with an automatic door lock. By locking the
door, two lock catches mesh with each other: The door is now in the
closed position.
After starting the program, the lock catches are moved into the locked end
position by a gear motor. The pressure tightness is only guaranteed in the
locked end position.
The controller then checks the correct procedure using a series of inputs
and outputs, thus ensuring safe operation of the device.
Closing
Door Open is shown in the display when the door is open.
• Close the door so that the lock catches mesh with each other. The
“Door Closed” reed contact is closed and the Door Open message no
longer appears: The door is now in the closed position.
Starting the program triggers a chain of events to lock the door securely.
The gear motor is started and moves both lock catches via a spindle into
the locked end position, which is defined by the “Door Locked” switch.
