15. Error codes.
The Pulson is built in a way that , during initialising, the most
important sequences are tested before the instrument can be used.
Under normal conditions, initialising takes about 2 sec., and is
displayed by a single point on the intensity display. If no errors are
detected, the initialising point disappears, and the instrument is
ready to be used.
If an error is detected, it will be displayed.
The timer display shows ERR and the intensity display the error
number.
ERR 1: ROM check fail.
The microprocessor detected a failure in its inside Eeprom.
Solution: Changing the microprocessor.
When a new microprocessor is installed, the upgrade routine
has to be
followed. ( see page )
ERR 2: Eeprom checksum fail.
The checksum result of the microprocessor is different from
the checksum
result of the Eeprom.
Solution: Change the Eeprom ( IC U10 ).
Since every Eeprom contains values specific for one output
stage, the US
output PCB and the Eeprom have to be returned to GYMNA for
recalibration.
ERR 3: Eeprom read
Solution: same as ERROR 3.
ERR 4: Eeprom write fail.
Solution: Same as ERROR 3.
Cab: Cable fracture detected.
This error can also occur during treatment.
The cable of the selected treatment head is broken,
and need to be replaced.
USH: In case of a USH warning, check following items:
Check all connections between the instrument and the
ultrasound head.
Open the head and check if all wires are connected.
Also check for visual damage.
Open the corresponding USH head, take out the
crystal and clean it.
Close the head and try again.
If the problem doesn’t disappear, the crystal
might be damaged.
Change the crystal and its corresponding efficiency
resistance ( in the connector).
