VÅNTEC-1 Detector User Manual Basic Operation
M88-E01072 9 - 3
9.3 Emergency Power-Down
Procedure
The mains power for the VÅNTEC-1 controller is
connected to X601, located on the left side of
the D8 lower enclosure.
1. In the event of an emergency, press either
Stop button located on the front side col-
umns to switch off power to the control elec-
tronics, high voltage generator, and the
VÅNTEC-1 controller and FDC (if present),
when the controllers are connected to X602.
Use the Stop button to immediately shut off
power to the X-ray source and stop all mov-
ing drives instantly. The Stop button should
only be used in emergency situations and
not for normal shutdown of the diffractome-
ter system.
The Stop button will not turn off the three AC
outlets (X601) that are located on the mains
distribution panel! Devices connected to these
AC outlets can only be switched off by the
internal automatic circuit breaker labelled F600
or the external power switch that is installed on
the user’s side close to the diffractometer. The
control panels of the D8 diffraction system are
located on the front side of the system. X602 is
supplied power as long as the D8 On/Off switch
(on the right-hand column of the D8 cabinet) is
enabled and the two emergency Stop switches
are not engaged.
2. To disengage the Stop button, turn the but-
ton clockwise and release. Re-apply power
with the Power On button that is on the right
side column of the D8 enclosure.
