Technical Manual
Er 52 mA or kV feedback cable open
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 k
Ω
, mA about 383R), measured at the
generator processor board inputs while cables connected, the board is faulty.
Er 53 Up/down motor does not consume power
If this error occurs, check the up/down motor condition and the motor cables.
NOTE If the unit is equipped with the STOP switch, check that it is not activated.
Er 54 Up/down motor consumes too much power
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.
Er 57 Exposure button activated
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.
3.8 Errors 60-61 (generator processor and AEC related errors)
Er 60 Supply voltage ± 15 too low
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.
Er 61 Generator processor does not respond
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 pro5 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.
Er 62 Limit sensor power missing
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.
Er 64 The radiation reaching the AEC sensor is very low or missing completely
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.
Er 65 The radiation reaching the AEC sensor is too high
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.
