ALARM
NOT ACTIVE
Code
T0
When
Starting exposure in automatic mode
Why
Film Screen or technique STD, EXT, LD, HC selected on the control panel is not
programmed.
Action
Select programmed Film Screen and technique STD, EXT, LD, HC.
If only one is programmed, freeze it by means of DIP5 SW1 PCB 01-170.
If problem persist it’s probably due to memory corruption, transfer again AEC calibration
curve to CPU memory
ALARM
EARLY PUSHBUTTON RELEASE
Code
Rp
When
During exposure
Why
Pushbutton has been released before the end of exposure
Pushbutton is defective
Action
Inspect pushbutton at sight, select high mAs value and during exposure force: cable,
connector and pushbutton to locate possible false contact.
Replace pushbutton.
Note
Display shows exposure mAs and kV
ALARM
LOW ANODE CURRENT
Code
Bt
When
After exposure in MANUAL mode
Why
Anode current was below lower limit or zero.
Exposure has been terminated by Back Up Timer.
Action
Check anode current calibration according to specific section of this manual.
Also check kV value according to specific section of this manual.
Alarm can also depend on malfunction of V/F converter onboard of PCB 92-073, event
counter on board of PCB 01-170 and cable CV0173.
To investigate mAs integrator, check LED5 PCB 92-073 and LED3 PCB 01-170
For further investigation, external Dose meter or radiographic cassette with film can be
used to detect if x-ray are generated or not.
LOW ANODE CURRENT could also be due to H.V. generator defect or failure, check it as
described in dedicated section of this manual.
