15.5 - Vacuum
The ESR analyser unit uses vacuum, for both aspirating and the rinse system. If problems occurs, it is most
likely because of poor or no vacuum.
Check the airflow, go to
Maintenance
tab -
Check sensors
and select
Check flow sensor
.
Note:
In User mode, the indicators are shown green the vacuum is ok. In Service mode the indicators
are will numbers.
The following values are shown on the screen:
Flow:
0980
± 60 Abs:
0320
±10 Offset:
0050
±5
If for example the blue disk filter blocked, the flow will be: 0050 (offset value).
Low value for the airflow may be caused by a dirty or blocked blue disc filter, or orifices (especially the
yellow one).
Start the pipette wash sequence via
Maintenance

Prime/clean
-
Wash all pipettes
and observe the drying
process, pipettes must be free of water spots.
15.5.1 - Vacuum stabilisation problems
The ESR unit checks the vacuum built up in a pipette just before Sampling. A vacuum stabilization error will
occur if it takes too long to evacuate a pipette or if vacuum level is not stable.
Vacuum stabilization error may caused by:
1. Leakage in sample tube connecting mixing-piece and fill nozzle.
▪ Replace the silicone sample tube.
2. Fill block washer defective or not in place.
▪ Needs replacement
3. Leaking O-ring in the fill nozzle,
replace the fill nozzle O-ring
.
4. Sample tube pinch valve (next to fill nozzle) not operating.
▪ Needs replacement
5. Wet or dirty blue disk filter on flow-sensor board, replace blue disk filter
6. Defective flow sensor board.
▪ Needs replacement
7. Needle vacuum valve is not functioning correctly and vacuum is leaking away, check needle vacuum
valve.
15.5.2 - Vacuum error
The ESR analyser unit monitors the vacuum pressure. If the vacuum pressure drops below a pre-set level, a
Vacuum error message will be indicated on the Main screen.
Vacuum error may be caused by:
