Eaton Power Xpert C445 Safety Manual page 13

The C445 will issue a control fault when:
A Run1 command is active and phase voltage is present
•
and no phase current is detected after the Control Switching
Time expires.
A Stop command is active and current is detected after the
•
Control Switching Time expires.
Outputs 1, 2 and 3 will be de-activated anytime the C445 expe-
riences a fault/inhibit condition.
Output 1 – auto transformer reduced voltage starter START
•
coil (NO)
Output 2 – auto transformer reduced voltage starter RUN coil
•
(NO)
Output 3 – auto transformer reduced voltage starter STAR
•
coil (NO)
Solenoid Valve Operation Mode
The Solenoid Valve operation mode accepts energize/ de-ener-
gize commands to open/close a solenoid controlled valve. The
control can be adapted to both normally open & normally closed
valves. An energize command will activate the Output 1. A de-
energize command will de-activate Output 1. Limit switches can
be used to provide feedback to the C445 indicating when the
valve reaches open/closed positions.
The C445 will issue a control fault when:
Both closed and open feedback is detected
•
Normally closed valve
An Energize command is active and no open feedback is
•
detected
A De-energize command is active and no closed feedback is
•
detected
Normally open valve
An Energize command is active and no closed feedback is
•
detected
A De-energize command is active and no open feedback is
•
detected
Output 1 will be de-activated when the C445 experiences a
fault/inhibit condition.
Output 1 – solenoid coil (NO)
Output 2 – open for user configuration and their function can be
selected by the user.
Output 3 – open for user configuration and their function can be
selected by the user.
MCCB Feeder Operation Mode
The MCCB feeder operation mode has two modes of operation
with actuation and without actuation.
When MCCB actuation is enabled, it provides remote control
capability for MCCB installed with motor operators. A close
command will activate Output 1 for the programmed pulse
width providing a close signal to the motor operator. An open
command will activate Output 2 for the programmed pulse
width providing an open signal to the motor operator.
MCCB Parameters :
MCCB Actuation Enable
•
Actuation Pulse Width
•
CB On & CB Alarm auxiliary relays provide feedback, reporting
MCCB feeder open, close, & trip status.
The C445 will issue a control fault when:
An Open command is active and the CB On feedback input
•
is true.
The CB On & CB Alarm feedback inputs are both "high" at
•
same time.
Current is detected after an open command.
•
A Close command is active and the CB On feedback input is
•
false.
When the C445 experiences a fault/inhibit condition Output 2
will be activated for the programmed pulse width to open the
breaker feeder.
Output 1 – close control (NO)
•
Output 2 – open control (NO)
•
Output 3 – open for user configuration and their function can
•
be selected by the user.
