Special features in active PROFIBUS
®
mode
3.1 General
The pump cannot be manually set or programmed
in PROFIBUS
®
mode! To do this, set the PRO‐
FIBUS
®
to „inactive“ .
n
Use button
[i] 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
®
mode. 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
®
mode, it stops and can
only be restarted using the PROFIBUS
®
.
3.2 Displays
There are other identifiers in the operating display when PRO‐
FIBUS
®
mode is running.
The current identifiers are listed in the “Control ele‐
ments” chapter in the "Operating instructions for
the solenoid metering pump delta
®
with controlled
solenoid drive optoDrive
®
” or the “Operating
instructions for the motor-driven metering pump
Sigma/ x Control type SxCb”.
Stop PROFIBUS
®
: The pump has been stopped by the PRO‐
FIBUS
®
. The master has sent the pump a corresponding telegram.
Connection error: If the pump loses its connection to the PRO‐
FIBUS
®
(for instance as soon as the PROFIBUS
®
is stopped), then
the fault symbol and the
symbol flash on the main display.
