3 Emergencies
Possible emergencies can result from a failure of the soft-close mechanism that stops
the door, if an obstacle prevents closing, see
Automatic Emergency Deactivation .
But if the soft-close mechanism fails and you have your hands in the way of the closing
door, your hands can get caught between the door and the chamber's frame. In this
case, use the
Emergency Stop .
3.1 Emergency Stop
To stop the chamber's door quickly at any time, interrupt the electric power supply.
To interrupt the electric power supply
1. Hit the panic button that switches power off.
See "Prerequisites for power connection" on page 36.
2. If no panic button is installed:
● Pull the power supply unit out of the grid power socket.
● Or pull the DC plug out of its socket on the rear side of the chamber.
See Figure 7-1 .
Interrupting the electric power supply has the following effects:
●
The door movement stops immediately.
●
The light in the Push-Button Switch Unit (if installed) is off, independent of the
door's state.
Also, the status LED next to the door is off.
●
The pneumatic system is depressurized and the door is left forceless. You can
push it open or close manually against a merely frictional resistance.
To reactivate the chamber, proceed as described in Chapter 7.1, "Activating the Cham-
ber" , on page 42.
3.2 Automatic Emergency Deactivation
During normal operation, the door closes tightly with high force to provide sufficient
shielding effectiveness. To prevent injury due to this forced closing, the door's
soft-
close mechanism moves with a lower force until it is almost closed: maximum 8 mm
gap remaining. The door mechanism switches to high force to close the final 8 mm gap
only if no obstacle stops this low-force closing.
