mands to control the contactor in a feeder application.
A close command will activate Output 1. An open command will
de-activate Output 1.
C445 Feedback Signal Source Selector parameter.
Input source of the feedback signals:
0 – No feedback source
•
1 – User interface inputs (In#2 – aux on)
•
2 – Base control inputs (In#2 – aux on)
•
3 – Fieldbus parameter
•
The C445 will issue a control fault when:
An Open command active and the Aux On feedback input is
•
true.
Current is detected after an open command.
•
A Close command is active and the Aux On feedback input
•
is false.
When the C445 experiences a fault/inhibit condition Output 1
will be de-activated to open the feeder.

Current Ranges Of The Overload Relays
The C445 motor management relays can be set to the rated
current of the motor using the communication cards.
The specialist personnel responsible for the installation shall
refer to the motor name plate or the approval certificate of the
motor when setting the overload relay current.
Motors with a rated current of 0.3 to 136 A can be managed
with the Measurement Module, the Base Control Module and
communication modules that are available in C445 family cata-
logue.
