Components of the Safety Lines

The various components of the safety lines work as follows:
K6/K7:
When turning on key switch S600 (i.e. the clockwise end position), the two relays K6 and K7 will close
and stay activated (enabling the two safety lines). If either of the safety lines is interrupted, both relays
will be switched off immediately.
K52/K53:
The switching contacts of the two contactors K52 and K53 turn on the high-voltage generation unit
inside the X-ray generator. As soon as this unit is activated, the connected X-ray tube will be supplied
with the specified electrical power. The values for high voltage and tube current will be set individually by
firmware.
If the two safety lines are closed, the contactors K52 and K53 can be turned on and off by firmware
control. If either of the two safety lines is interrupted, both contactors will be switched off immediately
and stop the generation of X-rays.
S651-S658:
Switches S651 through S658 check that the four side panels of the S8 TIGER are mounted correctly.
If any of these switches are interrupted (e.g. because panels are loose or not attached), high voltage
generation will be stopped immediately.
S659/S660:
Switches S659 and S660 monitor the position of the sample seal. They are located at the front edge of
the sample seal. They guarantee that the generation of high voltage can only be enabled if the sample
seal has been closed properly.
S661/S662:
Switches S661 and S662 are located at the rear side of the sample seal and check the position of the
sample seal. They make sure that the generation of high voltage can only be enabled if the sample
seal has been closed properly.
