LPX-200 FAULT MESSAGES
During operation, if a fault condition occurs, x-ray generation
automatically terminates and FAULT messages
appear in the Message / Mode LCD. The following is a list of
the fault messages that may appear and instructions on
correcting the fault.
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 check the jumper for proper installation.
FLOW:
Coolant flow from the Cooling Unit to the Tubehad has been
interrupted. Check that the Cooling Unit is
running, or check the twin coolant hose for proper attachment.
TEMPERATURE/PRESSURE:
The Tubehad has overheated or the gas pressure has dropped
below 25 psi. Make sure the Cooling Unit (liquid-cooled
units) or the cooling fan (air-cooled units) is working properly.
Check the gas pressure within the
Tubehead. If the pressure is below 25 psi @ 70
°
F, perform the
Re-pressurization or Re-Filling procedure (whichever is
appropriate) in Section 6 of this manual.
ARC DETECTED:
This fault condition is usually due to instability from a new
tube or from an inadequate warm up sequence. Restart the
system and perform another AUTOWARM sequence. If the
ARC DETECTED fault occurs repeatedly on restart, refer to
the X-RAY TUBE SEASONING (later in this section).
EXCESS kV:
This condition occurs if the drive voltage to the high voltage
invertor (in the Control Unit) exceeds a factory set
level. If the Excess kV fault occurs repeatedly after restart,
service is necessary.
X-RAY SW. ERROR:
Upon power up the computer checks the X-RAY ON button
for a short circuit and displays this message if a short is
detected. X-ray generation cannot be initiated in this
condition, and service is necessary.
