45 Instructions Handbook 1179.2948.02 ─ 01
To control opening and closing of the door manually, you can use the Push-Button
Switch Unit . Also, you can manually push the open door to let it close, see "Push door
to close it" on page 45.
Use the non-latching push-button switch unit as follows:
1. If the door is closed, push the button to open it.
The green status-indicating light in the button is switched off , and the door opens.
2. If the door is open, push the button to close it.
When the door is completely closed, the green light in the button is turned on to
indicate that the chamber is in a state ready for measurement.
Figure 7-3: Green light in the button indicates that the door is closed
When you disconnect the push-button switch unit from the chamber, the door remains
in its current position (opened or closed). Make sure to cover the unoccupied connec-
tor [X21] with the safety cap, see
Figure 6-10 .
If you use the push-button switch unit together with some remote control, refer to
Chapter 10.2, "Controller Conflicts" , on page 59.
Push door to close it
If the
DOOR_TOUCH_CLOSE
state is enabled, you can trigger the pneumatic closing
mechanism by giving the open door a manual push. Your push moves the door away
from its fully opened position and hence releases a sensor, which is integrated to
detect this position. When the sensor is released, it triggers the control module to close
the chamber automatically.
The
DOOR_TOUCH_CLOSE
function works in parallel with the push-button switch unit
and does not interfere with it. Both status LEDs in the push-button switch unit and next
to the front door behave as described above.
Similar to the loading mechanism in typical CD/DVD players, this function provides an
additional option for starting the automatic closing of the door, besides remote control
and using the push-button switch unit.
Note that the door control system returns an error message, if you push the door to
close it, while the
DOOR_TOUCH_CLOSE
state is disabled. See
DOOR?
on page 52.
