Self-Diagnosis indicators identify a malfunction in the system alerting operator
about error existence that inhibits exposure. During normal operation of the
system, these indicators are directly shown on the APR Display or as an error
code on the kV Display. (Also refer to Section 6.9).
DOOR OPEN: Indicates the X-ray room door is open when the X-ray equipment
is in use.
GENERATOR OVERLOAD: Indicates that the exposure has been interrupted
because during exposure has been produced arcing or bad function on the HV
circuitry (X-ray Tube, HV Transformer and/or HV Cables) or a failure of IGBT
module (overheated or defective IGBTs) has been detected.
It can be also shown making a high power and long exposure with the X-ray
Tube cool (X-ray Tube has not been warmed-up).
TUBE OVERLOAD: Indicates that either the technique selected is beyond the
X-ray Tube ratings or the present conditions of the X-ray Tube inhibit the
exposure (anode overheated). Parameters for next exposure may be
temporally limited by the Generator (change the exposure values or wait for the
X-ray Tube to cool).
Check that heat units available are lower than the calculated for the next
exposure (heat units close to zero). Reduce exposure factors or wait for the
X-ray Tube to cool. (To display the Heat Units refer to Section 6.6).
ROTOR ERROR: Indicates that the X-ray Tube anode is not rotating while
"Prep" is active, then exposures are inhibited.
HEAT: Indicates that the X-ray Tube thermostat / pressurestat is open due to
overheating of the Tube housing (housing is too hot, wait for the housing to cool)
or to a thermostat / pressurestat mal-function (housing is cool). Heat units may
raise to any value.
