Err 30: Power supply/reference mismatch
The microprocessor measures the correct values of +5V, ±12V and
Vref. If an incorrect voltage is found, the ASSISTANT delivers Err 30
and halts all functions.
PRIMING ERRORS
The errors described below are only delivered during the priming procedure.
They are often due to misuse, not to equipment malfunctions.
•
Err 11: Vac offset
Some vacuum is present at start of priming procedure although
aspiration pump has not been activated yet. This could be due to the
following reasons:
a) Priming has been restarted after an Err 13. Open the irrigation
clamp and restart
the priming procedure.
b) Cassette ha been left set on the console for several hours. Replace
cassette.
c) Vacuum sensor needs offset re-calibration.
•
Err 12: Major leakage
The peristaltic pump cannot built-up 100mmHg: There is a major
leakage in the I/A system. This could be due to one of the following:
a) The I/A cassette is not properly latched in position.
b) Test chamber is not installed on the sleeve.
c) I/A lines are not connected to the handpiece.
d) The cassette is defective.
e) Any of the valves (Irrigation, Reflux/venting, Venturi) is defective or
improperly
calibrated.
f) The vacuum sensor in the equipment is malfunctioning.
•
Err 13: No irrigation
To release the vacuum, the reflux/venting valve is open. If the vacuum
does not drop to zero, very likely no irrigation is flowing, irrigation
clamp on the line from the drip
chamber is closed or the line is bent (a
malfunction of the reflux/venting valve causes an Err 12).
•
Err 14: Aspiration occluded
After venting, the line are filled with BSS by the action of the peristaltic
pump. During this phase the vacuum should remain below 200mmHg.
If it builts-up to higher levels, the aspiration line is completely or
partially occluded. This could be due to:
