X-ray ON Indicators
IVIS Lumina XRMS Series III is equipped with three (3) red indicator lights showing the status of
X-ray generation:
Indicator on the main console control panel that is labeled "X-RAY ON" (Figure 6.5 on page 41).
This indicator operates independently, If it malfunctions, the remaining two indicators will
operate.
Indicator on the decorative camera top cover at the top of the main console (Figure 6.5 on page 41)
Indicator on the rear of the instrument.
The Living Image control panel also indicates the status of X-ray generation (Figure 5.4).
Safety Interlocks
IVIS Lumina XRMS Series III has several interlock switches. The primary interlock switch is
activated as soon as you turn the door handle. It is a micro-switch that when OFF (handle turned to
open position) prevents generation of X-rays or any image acquisition. Unless the door is completely
closed and the handle locked, the CCD camera shutter will not open.
A second redundant door interlock prevents X-ray generation by physically removing part of the X-
ray electrical circuit when the door is opened (Figure 5.6).
In addition to the two safety interlocks, the door has a solenoid-activated lock that prevents the door
from being opened during an imaging session when X-rays could be generated. For reasons discussed
in the warning above, it is important not to attempt defeat of any of these safety features.
WARNING! This product produces X-rays. Do not attempt to open the IVIS Lumina
XRMS Series III door when X-rays are being generated as indicated by the "X-Ray
On" lights.
WARNING! Do not, for any reason, attempt to defeat the built-in safety interlocks
described in this section. Operating the IVIS Lumina XRMS Series III without the
safety interlocks can result in exposure to X-rays. Exposure to X-rays may cause
serious bodily injury or death. Refer all servicing to PerkinElmer Technical
Support (see page 24.)
