Error
code Description of the error Response
(References to replacement methods are listed at the end
of the table.)
14000 Signal process error
−
Gain Overflow
Gain value has overflowed in
the gain/offset compensation
process during the PowerON/
Wakeup.
Confirm the operation of the LMC with standard current
read if it recur.
14001 Signal process error
−
Gain Underflow
Gain value has underflowed in
the gain/offset compensation
process during the PowerON/
Wakeup.
14002 Signal process error
−
Offset Overflow
Offset value has overflowed in
the gain/offset compensation
process during the PowerON/
Wakeup.
14003 Signal process error
−
Offset Underflow
Offset value has underflowed in
the gain/offset compensation
process during the PowerON/
Wakeup.
14010 Signal process error
−
QRV Overflow
PMT high voltage setup value
has exceeded the operation
guarantee voltage during the
sensitivity calibration.
Confirm the following when it recur.
1. Confirm that there is no mistake in exposure X-ray
condition and the service tool input dosage. (There is a
possibility that the exposure dosage is too small)
2. Replace the cassette and confirm the operation.
3. Confirm the connectors around the PMT and the LMC.
14011 Signal process error
−
QRV Underflow
PMT high voltage setup value is
lower than the operation
guarantee voltage during the
sensitivity calibration.
Confirm the following when it recur.
1. Confirm that the high voltage ON/OFF switch is ON on
the LMC. (It is ON if the image is displayed on the
console upon reading any image)
2. Confirm that there is no mistake in exposure X-ray
condition and the service tool input dosage. (There is a
possibility that the exposure dosage is too large)
3. Replace the cassette and confirm the operation.
4. Confirm the connectors around the PMU and the LMC.
