7 Malfunctions and Error Correction
7.1 General Malfunctions
Malfunctions are indicated in the "Process & equipment information
system" (see 6.3.5.4). An acoustic signal sounds when an error
message is generated.
Eliminate the source of the problem (see 7.1.1 to 7.1.4).
Acknowledge the error messages by pressing the right-hand
function key.
7.1.1 Error Messages
Type of error Possible reason Correction
No vacuum sensor signal The control unit receives an invalid
value from the vacuum sensor
Check the connecting cables
and plug-in connections of the
vacuum sensor. If necessary,
replace the vacuum sensor.
No rotor chamber sensor
signal The temperature sensor of the
rotor chamber is disconnected or
defective. Contact the after-sales service
(see 7.2).
No rotor sensor signal The rotor temperature sensor is
disconnected or defective Contact the after-sales service
(see 7.2).
No ice condenser sensor
signal The data communication link to
the cooling trap is interrupted, or
the ice condenser temperature
sensor is disconnected or
defective. Check the data link between the
rotational vacuum concentrator
and the cooling trap.
Lid cannot be opened The rotor chamber is not aerated
completely. Aerate the rotor chamber
completely.
Lid contacts error the system has detected an open lid
during evaporation.The rotor will be
stopped immediately. The lid must
be closed while the rotor is moving. Check the lid contacts. If
necessary, contact the after-sales
service (see 7.2).
Rotor overtemperature The maximum permissible rotor
temperature of 85°C has been
exceeded. If the system does not cool down,
disconnect it immediately from
the power supply. Contact the
after-sales service (see 7.2).
Chamber overtemperature The maximum permissible chamber
temperature of 85°C has been
exceeded. If the system does not cool down,
disconnect it immediately from
the power supply. Contact the
after-sales service (see 7.2).
Permissible imbalance
exceeded The rotor will be stopped
immediately, the process will also
be stopped.
- improper loading of the rotor
- glass breakage
- uneven evaporation Balance the load and restart the
rotational vacuum concentrator. If
the error occurs again, contact
the after-sales service (see 7.2).
VSK3000 calibration error Incorrect calibration of the vacuum
sensor VSK3000. The sensor must be recalibrated.
