Check whether the LED H11 is ON (ON=OK, OFF=NOT OK).
Possible causes:
1.
ambient temperature too high
2.
converter board defective
3.
temperature sensor defective
4.
power transistors defective.
If the converter board PQ1 needs to be replaced,
the service programs Tube calibration and Vf tube
editing must be performed (see the relevant para-
graphs of this section for more information).
The alarm is captured and stored as soon as it is detected.
Press the RESET pushbutton on the control panel to cancel the
alarm (if expired).
F.3.2 Cooling down
This alarm message appears on the display when the maximum
load admissible for the tubehead has been reached.
The host computer board PC1 keeps a constant check on the load
applied to the tubehead and when the maximum limit is reached,
it disables the possibility of making another exposure and displays
the cooling down time (in seconds).
The message appears on the display at the end of the reset
cycle and will disappear automatically when the count down is
extinguished.
If the alarm stays on it may mean:
1.
host computer board PC1 damaged
2.
flash memory of the host computer board damaged.
If the host computer PC1 needs to be replaced, re-
member to remove the EEPROM D38 from the old
board and mount it on the new one, otherwise all
the following parameters will be lost:
If you forget to do this, recover the information from
the System Configuration Chart (see Section C).
