Special features in active PROFIBUS
®
operation
3.1
General
The pump cannot be manually set or programmed in
PROFIBUS
®
operation! To do this, set the PROFIBUS
®
to ‘Inactive’ .
n Using the
[Clickwheel]
it is possible to switch between the continuous
displays at any time, as in the other operating modes. This does not
affect the operation of the pump.
n The settings from other operating modes are carried over when
switching over to PROFIBUS
®
operation. However, settings made
using the PROFIBUS
®
are not saved! They only apply as long as the
pump is linked to the PROFIBUS
®
. Only the total number of strokes
and the total number of litres continue to be counted and saved.
n If the pump is switched to PROFIBUS
®
operation, it stops and can
only be restarted using the PROFIBUS
®
.
3.2 Displays
There are additional identifiers in the operating display when PROFIBUS
®
operation is running.
The current identifiers can be found in the "Control ele‐
ments" chapter in the "Operating instructions for dia‐
phragm motor driven dosing pump Sigma X Control
type ...”.
Stop PROFIBUS
®
: The pump has been stopped by the PROFIBUS
®
.
The master has sent the pump a corresponding telegram.
Connection error: If the pump loses its connection to the PROFIBUS
®
(for instance as soon as the PROFIBUS
®
is stopped), an error message
with the symbol appears on the main display.
