Error Code
Cause / Meaning
Corrective Action
Cod01
•
The set dust bag fill level has been
reached.
• Change dust bag (Chapter 6.1).
Err01
•
Suction flow is blocked.
•
Insufficient compressed air pressure.
• Check the suction hoses for blockages, examine the dust
bag fill level, and change if necessary (See chapter 6.1),
examine the fine particle filter for contamination, and
change if necessary (see chapter 6.2.1).
• If the device is supplied with compressed air from a main
laboratory switch together with the air compressor, then
at first the compressed air will be insufficient and the
self-diagnosis will indicate a fault. Switch the device ON
at the On / Off switch (3, Fig. 1).
Err05
• Overheated electronics.
• Switch the extractor off and allow cooling. If the extractor
is located in a closed cabinet, make sure the exhausted
air is able to escape (See chapter 4.2).
Err26
• Suction hose A or B permanently open.
•
The fine filter is too clouded.
• Suction tube is blocked.
• Installation with excessively narrow
cross-section in the suction line.
• Make sure the pinch valve on the suction hose is not
blocked that the pinch valve membrane is not defect.
• Check to ensure that the pinch valve is assembled cor-
rectly.
•
Change fine filter (see chapter 6.2.1).
• Check suction channel from suction point to pinch valve
for blockage and remove if necessary.
• Check the suction tube from the suction point to the pinch
valve for cross-section restrictions and correct if possible.
If necessary, use tube connector adapter (see accesso-
ries).
Err51
• Error occurred whilst adjusting the start-up
threshold.
• Cancel the adjustment of the start-up threshold using
the menu key (30, Fig. 2) and enter the required setting
afresh as described in Chapter 5.3.4.
