Self-diagnosis Indicators
Self-diagnosis indicators identify a malfunction in the system alerting the
operator that an error is inhibiting exposure. During normal operation of the
system, these indicators are directly shown on the lower area of the console or
as an error code close to the “CONT.” button.

Indicator
Description
DOOR OPEN
Indicates that the X-ray room door is open when the
X-ray equipment is in use.
GENERATOR OVER-
LOAD
Indicates that the exposure was interrupted because
arcing or malfunctioning occurred during exposure
on the HV circuitry (X-ray tube, HV transformer
and/or HV cables) or a failure of IGBT module
(overheated or defective IGBTs) was detected.
It can also appear when making a lengthy or high
powered exposure with the X-ray tube cool (when
the X-ray tube has not been sufficiently warmed-
up).
TUBE OVERLOAD
Indicates that either the technique selected is
beyond the X-ray tube ratings or present conditions
of the X-ray tube inhibit the exposure (anode
overheated). Parameters for next exposure may be
temporarily limited by the generator (change the
exposure values or wait for the X-ray tube to cool).
ROTOR ERROR
Indicates that the X-ray tube anode is not rotating
while “Prep” is active. Exposures are inhibited.
OVERHEAT
Indicates that the X-ray tube thermostat/
pressurestat is open due to overheating of the X-ray
tube housing (housing is too hot, wait for the
housing to cool) or that there is a thermostat/
pressurestat malfunction (housing is cool). Heat
units may rise to any value.
