5.5 SELF-DIAGNOSIS INDICATORS
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 lower area of the console or
as an error code close to the “Reset Error” button. (
Also refer to Section 5.8 ).
DOOR OPEN : Indicates the X-ray room door is open when the X-ray equipment
is in use.
GENERATOR OVERLOAD: 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 (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 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 5.6).
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 a thermostat / pressurestat mal-function (housing is cool). Heat units may
raise to any value.
