Behavior
DS1
kV Empty
(during testing: kV applied,
no mA applied)
Yellow
Normally OFF
ON during use of proprietary maintenance menu
when only kV is applied but no mA is applied.
DS2
X-ray Exposure
Yellow
ON when an X-ray exposure is taking place.
OFF when an X-ray exposure is not taking place.
DS3
Polar Working
Yellow
ON when polarization is applied (e.g. either during
an X-ray exposure or via the use of the proprietary
maintenance menu).
OFF when no polarization is applied.
DS4
Heater Working
Yellow
ON when current is applied to the heater (e.g.
either during a preparation and an X-ray exposure
or via the use of the proprietary maintenance
menu).
OFF when no current is applied to the heater.
DS5
Track 2
(Track 2 = Rh)
Yellow
ON when the Rh track from the anode is selected.
OFF when the Mo track from the anode is not
selected.
DS6
Starter Working
Yellow
ON when the starter motor is rotating during a prep-
aration.
OFF when the starter motor is rotating (i.e. during
times other than the preparation phase).
DS7
Normal Anode Rotation Speed
Yellow
ON when the anode in the X-ray Tube is rotating at
a normal speed.
OFF when the anode in the X-ray Tube is not rotat-
ing at a normal speed.
DS8
Brake
Yellow
ON when the anode brake in the X-ray Tube is
active.
OFF when the anode brake in the X-ray Tube is not
active.
