Possible reason
If the inverter has been stopped
more than 3 times, the exposure will
be interrupted and the Err 23 mes-
sage is shown on the display.
•
Check the inverter current, refer to
the section "Error diagnosis HT
and single tank". Refer also to
"P13 - Inverter test".
•
The X-ray tube may have arced
during the exposure. If the first
exposure after a long interval is an
exposure with high kV values, tube
arcs can occur.
The unit has to be started with
several exposures at high mAs
values. The kV values selected
should be from 40 kV increased to
133 kV.
Refer also to "Error diagnosis HT
and single tank".
•
Check the supply voltage on D1,
see page 110**.
•
Check that the voltage in the
backup battery is > 2.8 V and that
the battery jumper is connected,
refer to page 110**.
•
If the message appeared once, a
tube arc may have disturbed the
program.
If the "Err 37" occurs repeatedly,
the single tank must be checked
according to section "Error
diagnosis HT and single tank". If
the function of the single tank is OK
and "USE 37" appears repeatedly,
replace D1.
