Alarm Text
Alarm Cause
Corrective Action
A31
Venous pressure test
failed
An error occurred during
the calibration of the
venous pressure (PV) and
the inlet pressure on the
plasma filter (PBE).
Ensure that:
The pressure transducer for the PV is
correctly screwed on.
The pressure transducer for the PBE is
correctly screwed on.
The pump segment is inserted in the
reinfusion pump.
After eliminating the the cause of the alarm
and acknowledging the alarm, the test is
automatically repeated
.
A 32
Heater test failed
Malfunction of heater
Inform technical service.
A 33
HAK test failed, check
insertion line?
Line not correctly inserted
in HAK clamp
Ensure that:
The filtrate line is inserted correctly in the
HAK clamp.
A 34
2 ml air infused
SAD has detected a total
of > 2 ml air
Ensure that:
The lines have no leaks. When leaks are
found, replace the respective line.
All components have been connected firmly
and properly.
The venous chamber is sufficiently filled. If
required, fill the venous chamber manually.
A 35
Blood leak detector
(BLD) calibration failed
Malfunction of blood leak
detector
Inform technical service.
A 36
Blood leakage from
plasma filter
The BLD detects a blood
leak or larger air bubbles
in the line
Perform a visual inspection of the line after
the plasma filter. Replace the plasma filter
when a blood leak is found (see 8.3.4).
If air bubbles are found, check the
connections for firm seating and the lines for
possible damage.
A 37
Air in venous line, set PV
to -50 mmHg and
acknowledge alarm
Air found in venous line
Clamp shut the venous line with the clamp
between the plasma filter (venous outlet) and
the venous chamber.
Using the level adjustment button of the
venous air chamber, adjust the PV to – 50
mmHg.
The safety air clamp (SAK) opens automatically
and the air is removed from the venous line into
the venous chamber.
Open the clamp on the venous line.
Acknowledge the alarm.
Continue the treatment.
Using the level adjustment button, manually
adjust the level in the venous air chamber
again.
A 38
Minimum arterial
pressure (PA)
Arterial pressure too low
Ensure that:
The arterial access is free and properly
connected.
If necessary, reduce the blood flow.
