Sealed X-ray tube
The inspection system can optionally also be operated with a
sealed X-ray tube.
The sealed X-ray tube is described in the following sections:
Overview
Shutter
X-ray output window
Battery
Monitoring the warning lamp signals
Life span
Overview
The sealed X-ray tube consists of three components: a micro-focus
X-ray tube to generate X-ray radiation, a high voltage generator
circuit and a control circuit; all contained in one unit. This unit can
be operated and controlled from an RS-232C interface. The sealed
X-ray tube is movable in the Z-direction.
The standard system version uses a 130 kV tube, arranged verti-
cally over the PCB. For additional information about technical spec-
ifications, see „Technical specifications“ > „Sealed X-ray tube“
(Page 255).
The following graphics illustrate the sealed X-ray tube construc-
tion.

Shutter
The shutter isolates the X-ray tube during operation with an open
lift gate to prevent X-ray radiation leakage.
X-ray output
window
The X-rays are emitted from this window. It consists of beryllium.
After dismantling the tube a protective cover has to be attached to
this window in order to prevent contact with beryllium. The safety
instructions concerning the handling of beryllium must be
observed, see „Safety“ > „Chemical hazard“ (Page 23).
Battery
The sealed tube has a battery (Type CR2032). The software indi-
cates the time the battery must be replaced. To exchange the
battery, the X-ray tube must be dismounted. According to the
maintenance schedule, the battery has to be replaced every 3
years, see „Maintenance“ > „Exchanging the battery“ (Page 220)
Monitoring
the warning
lamp signals
The XLC assembly monitors the warning lamp signals and makes
sure that the functional warning lamp reports the failure of the
other lamps to the operator by blinking.
NOTICE
If one warning lamp fails, the radiation is switched off.
Life span
The driver of the sealed x-ray tube monitors a measurement
value, the cathode level, for display of the tube lifespan. There are
5 levels in all. If the current cathode level reaches value 1, a
warning mask with the text "Please note: Cathode level is 1" is
displayed. Then the tube is approaching the end of its lifespan, but
can still be used for about 1000 hours of irradiation time.
Mask: Cathode level
Viscom recommends planning installation of a replacement tube at
an early stage, to avoid unnecessary line downtime.
