menu also appears.
The pump is in "stop" mode. To start controlling it, press
the
[Stop/Start]
key. Give the Start command using the
BUS.
While the PROFIBUS
®
is
‘Active’
, all external inputs such as level
monitoring, metering monitoring and external control (pause, con‐
tact input, analogue input) will function. They lead to the expected
reactions as in the case of the pump without PROFIBUS
®
function‐
ality - see pump operating instructions. The pump sends corre‐
sponding information over the PROFIBUS
®
to the master (PCL, PC
etc.).
The gamma/ X, GMXa is set to
‘Automatic’
metering type at the
factory.
Even if the fieldbus is set to inactive, the master is able to read-
access the pump data defined in its GSD file.
If the PROFIBUS
®
is set to
‘Inactive’
, the settings for the operating
mode previously selected are reloaded.
If the pump is switched to another operating mode, it stops and can
only be restarted using the
[Stop/Start]
key.

address is cancelled.
The address is set to "120" for the gamma/ X
GMXa.
