GWA 4NEB 535 2195-02 DS 06
A local device interface on the front side of the starter is provided as standard.
This interface can be used to connect either an optional external operating and
display module, or the "Soft Starter ES" operating, monitoring and
parameterizing software (refer to Chapter 10.3.9 "Accessories", Software) using
a PC and connecting cable.
The SIRIUS 3RW44 soft starter can be equipped with an optional PROFIBUS
module (only available for products delivered after 04/06). The soft starter can
be connected to PROFIBUS, operated and parameterized via the interface. The
"Soft Starter ES" operating, monitoring and parameterizing software (refer to
Chapter 10.3.9 "Accessories", Software) can also be connected to this interface
using a PC and connecting cable.
Simultaneous operation of a 3RW44 with a PROFIBUS interface is not possible
in networks where one external conductor is grounded.
When de-energized, the external display and control unit can be connected to
the local device interface via a special connecting cable.
After being switched on, the SIRIUS 3RW44 soft starter automatically
recognizes that the external display and control unit has been connected. The
3RW44 display will be inverted and the display and control unit's display will be
shown normally.
The control keys of the 3RW44 will be inactive, meaning that normal handling is
only possible via the external display and control unit.
