5.1. General notes for Operation
All configuration data, measurement and controller parameters can be accessed with the
-key from the operator’s screen.
The last line in the respective setting menu shows the keys that effect the respective
cursor position.
Every set value can be changed directly at its position in the setting menu. The cursor must
be positioned on the corresponding selection and can then be moved to the set value with
the -key. The
keys are used to set one value from between specific limits. The value
is changed by one digit through pressing one of the two keys once. The value changes
continuously if the key is pressed for a longer period; the value at which point the
corresponding arrow key is released is the one that remains. The value is adopted through
operating the ENTER key. The -key is used to cancel the respective setting.
If set values have changed, these are saved during the change to the operating level
(measurement screen). Only the changed values are adopted.
All the controllers are turned off when adjusting the values in the configuration menu, i.e.
fast processes can result in significant set point deviations during the adjustment phase.
The effects of significant set point deviations must therefore be determined in advance
and suitable counter measures should be implemented if required.
The same applies when operating the device using "manual functions". Here too all control
system functions are switched off. The effects of manually operated pumps, valves etc. on
the process must be considered whatever the circumstances
