Basic Operation VÅNTEC-1 Detector User Manual
9 - 2 M88-E01072
9.2 VÅNTEC-1 Power-Down
Procedure
1. Press the high voltage enable button on the
front of the VÅNTEC-1 controller. If the high
voltage button is not illuminated, this indi-
cates that high voltage for the detector is
OFF.
2. Press the I/O button on the front of the VÅN-
TEC-1 controller to switch off the mains
power.
Wait 60 seconds after turning off HV power
before removing the HV connectors!
3. Press the Power OFF button (O) on the D8
enclosure’s right-hand column to stop
power to the control electronics, high volt-
age generator, and the VÅNTEC-1 control-
ler and FDC (if present), when the
controllers are connected to X602.
4. Before switching off the diffraction system,
reduce the high voltage and current of the
generator to the lowest values (e.g., 20 kV/
5 mA) using the control software (e.g., XRD
COMMANDER).
5. Turn off the high voltage generator by turn-
ing the rotary switch “High Voltage” to the
left side. The X-RAY ON displays will turn
off.
6. Switch off the instrument by pressing the
enclosure’s Power OFF button.
Failure to reduce the generator high voltage and
current prior to shutting off the D8 could
significantly reduce the lifetime of the X-ray tube
and the high voltage generator.
