18.3 Mechanical Problems
Most mechanical problems arise because of some physical blockage of the moving
parts. Problems caused by severe blocks are most often accompanied by a grinding
noise. The noise is a result of a motor not being able to move – however most of the
time this will not cause mechanical damage to moving parts.
Typical situations can be traced back to salt build-ups around the wash head or the
shear valve. Incorrect operation of cleaning of the system – especially after long
inactive periods of time can cause valves or tubes to get filled with somewhat dried
salt. These problems can be the sources of dilutor motor noise.
In extreme tube or valve clogging situations the pressure built inside the dilutors can
cause some tubes to be released from their connections. This symptom is not normal,
but will not cause damage to the system. However, it is recommended to contact
Service Personnel to sort out the cause and resolve these problems.
18.4 Sample Rotor (SR) Failures
18.4.1 SR Gives Grinding Noise And / Or SW Displays SR Error Messages
•
The front panel is not closed properly
- The opening does not match with the sample rotor door
•
There is liquid in the SR, if you can see traces of salt around the SR, contact
service
•
Check the washing head for contamination (blood and salt) as excessive salt
build up can prevent the wash head to lift up effectively and the sample rotor
door can get stuck
