X
Dispensing sensor is dirty
or pressure sensor is faulty
(x=1-6) A) If a cassette can be inserted
without error (single acoustic
signal), the error message
indicates a very dirty ’dispenser
sensor’ (PSDx) photosensor in
dispenser module ’x’ which
must be cleaned. Then execute
a Reset (set CMD-V4 to
dispensing position).
Note:
When this error has occurred for
the first time, the CMD-V4 will
continue to function until operation
shuts down automatically when the
level of dirt increases.
B) If a cassette cannot be inserted
(and there is no acoustic signal
even after a few seconds), the
dispensing unit or controller
must be replaced after
inspection of the connectors on
the CMD controller and the
pressure sensors (PSDx).
