Operation
The analyzer can be operated in three different modes. These modes can be accessed at any time
via the "MODE" softkey. The user can switch the modes as he wishes. Restrictions only apply due
to current operating states.
The mode can be changed at any time, even if an action is running. However, the action must be
completed before the mode change can take effect.
9.6.1
Manual
The device is in the manual mode when it is delivered or following a device reset.
The analyzer waits for manual input (Menu/Setup/Manual operation). In this mode, it is not
possible to access the device from the outside, e.g. via a fieldbus. This can be relevant for safety
during maintenance tasks, such as changing the bottles or dispensers.
If accessing via the web server, it is possible to access the analyzer in the manual mode.
Some operations, such as maintenance activities, are possible only in manual mode.
9.6.2
Automatic
The individual actions (sampling, measuring, cleaning, calibration and maintenance) are
performed in the automatic mode. Measuring sequences, calibrations and cleaning intervals can
be configured (see the "Analyzer" section). Only adjustments are performed in the automatic
mode.
When the automatic mode is activated, two options are available:
•
Continue automatic mode
This is only possible if the automatic mode has been active beforehand.
The time and date stamp are retained.
•
Start automatic mode
The time and date stamp are reset.
If "Immediate" has been selected as a Start conditionfor measurement, calibration or cleaning,
these activities start immediately.
9.6.3
Fieldbus
Remote access can take place via fieldbus (e.g. Modbus).
Further information on fieldbus communication can be found on the product pages on the
internet at www.endress.com/ca80ph (-> SD01189C, SD01293C, SD01190C).
