S8 TIGER X-ray Spectrometer Introductory User Manual
Delayed control of the sample seal drive
When turning on the X-ray generator high voltage, the sample seal motor will be disconnected from its
electrical control circuits by the safety relays K3 and K4. The sample seal drive remains disconnected
as long as the two contactors K52 and K53 are turned on.
After switching off the high voltage generator, the two relays K3 and K4 remain turned off and will not
be activated before a defined delay time has completely elapsed. Therefore, the delay circuit ensures
that the sample chamber cannot be opened before the high voltage has been turned off completely.

X-ray Warning Displays

Two directly connected X-ray warning displays indicate the status "X-ray ON". Each display consists of
two LED illumination panels. The warning displays are controlled by the contactors K52 and K53 and
are illuminated when the high voltage is switched on. The current through the displays is continuously
checked by the microcontroller. In case of any error, the safety relays K1 and K2 interrupt both safety
circuits and instantly switch off the X-rays.

Optional External X-ray Warning Display

A fail-safe external X-ray warning display can be connected to the instrument if requested. It will be
controlled by safety relay K5 and is monitored by the micro controller. In case of any error, the safety
relays K1 and K2 will interrupt both safety circuits and switch off the X-ray generation immediately.
