Understanding the meaning of the above error messages may help in
troubleshooting ASSISTANT malfunctions.
• Err 01: Serial comunication fault
The User interface software checks the correct serial communication
between the 391130 PC board that controls the graphic interface and
the 393200 Control board controlling the surgical functions of the
equipment. If this vital communication cannot be estabilished, the Err 1
message is delivered. This could be due to a malfunction of the
393200 or to a missing hardware link between the two boards
(detached connector or wire), referring to the 391000 Wiring diagram,
check the connection 391538 between CN6 of the 391130 and J7 of
the 393200.
• Err 02: Low input pressure
This message is generated by the closure of the pressure switch
(Fig.4a, ref.5). The ASSISTANT should be supplied with a pressure in
the 5-8 bar range (72.5-116PSI). If the input pressure goes outside this
range (less than 4.5 or more than 9bar, 65.29-130.6PSI)), Err 2 is
delivered. Before attempting recalibration of the pressure switch and/or
of the input main pressure regulator, verify that the actual value of the
air supply pressure falls in the 5-8 bar (72.5-116PSI) range.
• Err 03: Cassette missing or full
This error is generated when there is no reading from the Tank full
Optic sensor (when the internal surface of the cassette is wet at the
level of the sensor, the infra-red beam is not reflected nor read by the
sensor. If the alarm is generated when the cassette is correctly
installed and empty, re-calibrate the sensor position (refer to”TANK
FULL ALARM CALIBRATION”)
• Err 04: Aspiration Halted
This alarm is consequent to Err03, if the cassette is not replaced within
approximately 50 seconds of aspiration from Err03, the aspiration is
halted to prevent damages due to fluids reaching the internal parts of
the equipment and Err04 is notified. The error disappears is the
cassette is replaced.
• Err 08: Diathermy power mismatch
The equipment checks the actual supply voltage to the diathermy final
amplifier against the preset power. If a mismatch is found the error is
