! CAUTION!
Tube current (mA) can be
attained up to the maximum
value it can produce at the Kv
level up to the rating of the tube. At no time
should the tube be permitted to operate above
the rated current. Lower Kv settings will
inhibit x-ray generation. See specification
sheet for Kv, mA, and power ratings for the
specific SPX model number.
8. The exposure will continue for the
duration set by the operator, after
which time the unit will automatically
shut off. During the exposure, x-ray
emission can be interrupted anytime
by pressing the red X-RAY OFF
E-STOP. To restart an interrupted
exposure, t w i st E - S T O P b ut to n t o
re le a s e an d press the X-RAY ON
switch.
For detailed operation
procedures and program settings,
see section 4 of the SPX user guide
9. At the end of the exposure, turn the key in the
SAFETY KEYSWITCH to the LOCKED OFF
position. Remove the key while making any
positioning adjustments to the Tube Head or
replacing film holders. To repeat the
exposure, re-insert the key and turn it to the
ON position and press
10. the X-RAY ON button. If the next exposure
requires new parameters, scroll to the
appropriate menu on the display screen to set
in the new parameters, then turn the key to
the ON position and press the X-RAY ON
switch.
11. If further operation is not necessary, leave the
key to the ON position and allow the Cooling
Unit, or cooling fan (air cooled units) to
operate for an additional five minutes.
NOTE... The Cooling Fan MUST BE allowed
to operate for five minutes after the
exposure before turning the unit OFF.
During this time, heat generated at the
anode during operation is dissipated.
12. Turn the key to the off position. Remove the
power cord from its source, disconnect all
cables and hoses, and replace all covers.
Place the key in a safe, controlled area to
prevent unauthorized use of the unit. Store
the x-ray unit in a cool, dry location that
provides secure storage.
FAULT MESSAGES
During operation, if a fault condition occurs, x-ray
generation is automatically terminated and FAULT
messages will appear on the displayscreen. The
following table lists the fault messages that may
appear and instructions on how to remedy the
fault.
1. Interlock: The connection between pins
"A" and "B" of the INTERLOCK connector
has been interrupted. Check that the
interlocked enclosure door switches are
operable and closed, or that the jumper is
properly installed.
2. Temperature/Pressure: The Tube Head has
overheated or the gas pressure has dropped
below 25 psi. Make sure the Cooling Fan is
working properly. Check the gas pressure within
the Tubehead. If the pressure is below 25 psi @
70º F, perform the Re-pressurization
procedures in Chapter 7,
“Re-Pressurizing the
Tube H
ead”, on page 33 of this manual.
3. Arc Detected: This fault condition is usually
due to instability from a new tube or from an
inadequate warm up sequence. Re-start the
system and perform an additional warm up
sequence. If the ARC DETECTED fault occurs
repeatedly on restart, service is necessary.
4. Over Voltage: This condition occurs if the
output voltage kV exceeds a factory set level. If
the Over Voltage fault occurs repeatedly after
restart, service is necessary.
