8.4 Diagnostic messages table
Important: The messages are listed in descending order of priority. Example: If
both
NO OPTICAL IMAGE
and
TEMP MEASUREMENT FAULT
are activated, only
NO OPTICAL
IMAGE will be shown. The wash related messages have priority only during the wash
cycle (preconditioning–wash–recovery).
When a relay is configured with FUNCTION INSTRUMENT OK (see Section 6.3.1), it is
closed when there’s no equipment malfunction i.e. instrument is ok.
Certain malfunctions cause the mA measurement to return to the mA default output
value (Section 6.3.3), see the table below.
