2. X-RAY SAFETY

followed by a single audible beep. If there is a failure in the lamp, a continued
beeping will be audible and the Portaspec will be inoperative until the lamp is
replaced. The replacement lamp is a 12PSB. X-rays can not be generated when the
lamp is burnt out or missing.
2.4.2 X-ray On Alert . Simultaneous to the red x-ray on lamp illuminating,
identifying that x-rays have been energized, a single beep will be audible.
2.5. Visual Indicators.
2.5.1 Fail Safe X-Ray on Warning Light
The “fail-safe” x-ray on warning light illuminates red when the Portaspec is
generating x-rays. If the lamp fails or is removed from its socket, the Portaspec
will no longer be able to generate x-rays.
2.5.2 Portaspec Control Software X-Ray On Indicator and Timer Display Form
In addition to the visual and audible x-ray on alerts on
the Portaspec, the Portaspec Control Software pops
up and displays the condition of x-rays, when x-rays
are activated.
The indicator form declares that x-rays are on and
displays the x-ray intensity in kV and mA.
The duration for x-rays to be energized is displayed
by the progress bar and is a function of the number
of Readings per Sample times the count time in
seconds. In the example in
Image 2-5 , the duration
for x-rays to be on is 90 seconds.
2.6 X-ray Interlock Switches
The Portaspec can not be operated, nor can x-rays
be generated, without the use of a computer with the
Portaspec Control and Analysis program installed.
Fundamental to the Portaspec, are two separate x-ray interlock circuits. All switches
in both circuits are wired in series, making it impossible to generate x-rays with a
single switch open or inoperative.
The control program has the ability to read the status of the interlock circuits and
x-ray on light and will not allow for x-rays to be generated with an interlock switch
open. Additionally, the controller circuit board installed in the Portaspec requires
a sequential protocol of two commands from the control software, in order to turn
on x-rays.
If, when operating the Portaspec, x-rays are interrupted by turning the X-Ray On key
to the “Off” position or by any other method of opening an interlock switch, x-rays will
not toggle ba
ck on when the key is turned to the “On” position or, if the interlock fault
is corrected. This safety feature diminishes the inadvertent activation of x-rays.
