Chapter 5—System Configuration and Operation
Contactor Feeder Operation Mode
The Contactor Feeder operation mode accepts open/close
commands to control the contactor in a feeder application.
A close command will activate Output 1. An open command
will de-activate Output 1.
In this mode, an input can be used to accept feedback on
●
contactor on status from an Aux contact. If this feedback is
provided, C445 will issue a control fault if the commanded
state does not match the feedback signal. The parameter
"Feedback Signal Source" selects where the inputs are
wired to the C445. Options include the Base Control
Module, the Control User Interface or to a controller where
they are sent to the C445 via a communication network.
For all three locations these input feedback signals may
be wired, the actual input or bit is pre-defined for each
as follows.
0 – No Feedback Source
●
1 – Base Control Module: Input 2 (Aux On)
●
2 – Control User Interface (C445UC..): Input 2 (Aux On)
●
3 – Input Register 602 from a controller: Bit 1 (Aux On)
●
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.
Output 1 – feeder contactor coil (NO)
●
Outputs 2 and 3 – open for user configuration and their
●
function can be selected by the user.

Contactor Feeder Operating Mode

Figure 104. C445UM: Monitoring User Interface

The Monitoring User Interface can be used with any
operation mode. If selected as a local control source, the
User Interface Start (Close) and Stop buttons are enabled
in Contactor Feeder Mode. Users may optionally disable
local start (close) or reset functionality if desired.
C445UM may still be used in Contactor Feeder if the User
Interface is not the local control source. Start, Stop and
Auto buttons will be disabled. If pressed, the screen will
notify the user that this functionality is not enabled. Control
Status LEDs indicating running, stopped and Auto status will
still function.
