Errors 60-61 (generator processor and AEC related errors)

Er 60 Supply voltage ± 15 too low
Er 61 Generator processor does not respond
Er 62 Limit sensor power missing
Er 64 The radiation reaching the AEC sensor is very low or missing completely
Er 65 The radiation reaching the AEC sensor is too high
Technical Manual
Before each exposure and after pressing READY the kV and mA feedback signals are meas-
ured. If the result is too high it is assumed that the cables are not properly connected.
If seems ok by resistance measurement (kV about 16 kΩ, mA about 383R), measured at the
generator processor board inputs while cables connected, the board is faulty.
If this error occurs, check the up/down motor condition and the motor cables.
If the unit is equipped with the STOP switch, check that it is not activated.
There can be a fault on the up/down motor control electronics. This error can also occur because
of the up/down motor cable short circuit, or if the motor is jammed.
If the exposure circuit is activated when the unit is turned on or service mode is entered, Er 57
occurs. This is to prevent unintentional exposures.
Generator processor board analog circuits have operating voltages of ±15V.
If these are below about 12.5V this error is indicated.
If disconnecting the cable to cassette end limit sensor board cures this error, then this cable and/
or sensor board is shorting the + 15 V.
Otherwise faulty generator processor board.
If the generator processor is not responding to the calls of the keyboard (master) processor oper-
ation is stopped with this error indication.
- +33 V operating voltage below 24 V.
- Serial communications cable broken
- No power to the generator processor
- One sensor is shorting the generator processor +5 V
- Faulty software EPROM in the generator processor
- Generator processor defective
- Measure voltages and cables to locate problem. Try to disconnect sensors and motors from
generator processor. Replace EPROM.
This error occurs when the power detected from the Keyboard CPU limit sensor: up/down, layer
or temple rest is missing. Check the sensors. Replace the Keyboard processor board.
Check that the cassette is AEC compatible, i.e. marked with text "AEC COMPATIBLE". If the
cassette type is correct, perform the AEC calibration, refer to section "AUTOMATIC EXPOSURE
CONTROL (AEC) CALIBRATION" on page D-26. If the calibration does not correct the situation,
change the AEC slide frame assembly.
If the cassette is in the cassette carriage and the patient is positioned when this error occurs, per-
form the AEC calibration, refer to section "AUTOMATIC EXPOSURE CONTROL (AEC) CALI-
BRATION" on page D-26. If the calibration does not correct the situation, change the AEC slide
frame assembly.
