Diagnostics
against either Control Panel. After releasing a stuck key, press any C-Arm control panel key to continue. A malfunctioning control
panel key may interfere with operation if you attempt to continue.
KEY SWITCH IN STANDBY - X-RAYS AND LIFT DISABLED - This message appears when the X-ray disable keyswitch on the
generator is turned on (key handle vertical) , preventing movement of the vertical column and generation of X-rays. Place the key
handle in the horizontal position to enable X-rays and vertical column movement. If the keyswitch is already in the ON position,
there may be a fault in the keyswitch or other associated hardware.
KV ON IN ERROR - This message appears when the system detects that the X-ray tube current is on, but no X-ray switch is
pressed. The system shuts down immediately.
LIFT SWITCH STUCK - PRESS ANY KEY - You will see this message when either C-Arm lift switch has been in the ON
condition for 30 seconds or more. All generator functions are inhibited until you press any C-Arm Control Panel key clear this
message. If the message persists, look for something pressing on the switch, a faulty switch, or a faulty lift circuit.
LOADING LOW DOSE ABS - This message appears when you select the Low Dose ABS table as the current ABS table in the
generator.
LOADING STANDARD ABS - This message appears when you select the Standard ABS table as the current ABS table in the
generator.
MA ON IN ERROR - The system displays this message when mA Sense is on and no X-ray switch is activated. This error shuts
the system down completely.
MA SENSOR FAIL - This message appears alternating with technique when the system detects a failure in one of the mA
sensors. If message persists, check HV tank sense points, and check the HV Supply Regulator PCB.
OVERLOAD FAULT - This message may indicate a fault in the high voltage regulator circuit. The first time this fault occurs, the
message appears only briefly after an exposure. The second time this fault occurs, the system automatically shuts down and the
message remains on display. If message persists, look for excessive current in the series-tuned circuit inductor (L1), and check
for a HV tank or X-ray Tube arc.
OVERVOLTAGE FAULT - This message may indicate an X-ray generator failure. The first time this fault occurs, the message
appears only briefly after an exposure. The second time this fault occurs, the system automatically shuts down and the message
remains on display. If message persists, look for excessive current in the series-tuned inductor (L1), and check for a HV tank or
X-ray Tube arc.
PLEASE WAIT - This message appears while the system performs internal processing. X-rays are disabled during this period.
