Errors 70-75 (Software Errors) - Planmeca Proline XC Technical Manual

Chapter C - HELP & ERROR MESSAGES
Er 61 Generator processor does not respond
If the generator processor is not responding to the calls of the keyboard (master) processor
operation 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.
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 6 "AUTOMATIC EXPO-
SURE CONTROL (AEC) CALIBRATION" on page D-34. 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,
perform the AEC calibration, refer to section 6 "AUTOMATIC EXPOSURE CONTROL (AEC)
CALIBRATION" on page D-34. If the calibration does not correct the situation, change the
AEC slide frame assembly.

3.8 Errors 70-75 (software errors)

Er 70 Conflicting commands in communications line
If the generator processor is receiving conflicting commands from the keyboard processor (for
example drive cassette back and forth at same time) the operation command is ignored, all
activity is ceased and this error code is sent to the keyboard processor to be put on the dis-
play.
- Not matching software versions in generator and keyboard processors
- Faulty keyboard processor board
Er 71 Generator processor program memory failure
At power up the generator processor calculates a check sum from the program memory cir-
cuit (EPROM). If it doesn't match all operation is ceased and an error code is sent to key-
board processor. If the EPROM is completely broken it is obvious that this kind of error code
cannot be sent but more likely the Er 61 will be displayed. This error indication is merely
meant to detect a single EPROM failure before complete break down.
- The generator processor EPROM is to be changed immediately
