Direct Operation Mode
Description
Direct Motor starter is the default profile. The Direct Motor
starter profile will use the motor1 parameters for all control/
protections.
C445 outputs:
●
Output 1 is dedicated by this application mode for
controlling and protecting the motor
●
Outputs 2 and 3 are general purpose
Output 1 controls and protects the contactor/motor. It will
close when a valid RUN command is received by the C445,
provided a fault or inhibit is not active and will open on a
STOP command or if a trip occurs. A C445 Trip condition will
cause the Output contact to open.
Outputs 2 and 3 are user configurable outputs and their
function can be selected by the user.
The C445 will issue a control fault when:
●
Run command is active and phase voltage is present
with no phase current detected after delay expires
●
Stop command active and current detected after
delay expires

Figure 64. 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 and Stop buttons are enabled in Direct
Mode. Users may optionally disable local start or reset
functionality if desired.
C445UM may still be used in Direct Mode 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.
