Err 5* During
exposure
No X-ray tube cur-
rent. The measured
tube current < 5 mA
("MAPOS" < 50 mV).
The check starts 0.8 ms after the
exposure is started and ends at the
end of the exposure. If an error
occurs, the exposure is normally
interrupted earlier by "Err 3" or
"Err 23".
If the message appears in connec-
tion with service or maintenance on
the generator, a defective connection
may be the cause.
• Check the connections K64/1 and
K64/2 on D13 and the K64
connection to the single tank, see
page 140**.
• Check cables K9 and K8, see page
140**.
• Check main fuse U101, see page
140**.
• Check the trigger pulses INV A and
INV B to the inverter, page 140**.
• Check the capacitance in the
capacitor bank, see section
"P03 - Capacitor bank and
charging test".
• Check the current to the single tank
and compare it with the curves in
section "Error diagnosis HT and
single tank".
