4.2 Device Interfaces
4.2.1 Local Device Interface
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 smart" operating, monitoring and
parameterizing software (refer to Chapter 10.3.8 "Accessories" , Software) using
a PC and connecting cables.
4.2.2 Profibus Interface (Optional)
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, operated and parameterized via the Profibus interface. The "Soft
Starter ES professional" operating, monitoring and parameterizing software
(refer to Chapter 10.3.8 "Accessories" , Software) can also be connected to this
interface using a PC and connecting cables.
Simultaneous operation of a 3RW44 with a Profibus interface is not possible in
networks where one phase conductor is grounded.
4.3 External Display and Control Unit (Optional)
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 of the display and control unit will be
showed in a normal way.
The control keys of the 3RW44 will be inactive so that normal handling is only
possible via the external display and control unit.
