Chapter 5—System Configuration and OperationPower Xpert C445 Global Motor Management Relay MN042003EN—January 2019 www.eaton.com 99Control SettingsThe following parameters are used to configure the MCCBFeeder Operation Mode and the C445 sources of control.Table 19. MCCB Configuration ParametersNote1 Soft reset (power cycle) required for changes to these parameters to take effect.Fieldbus Control WordThe MCCB feeder control profile will accept the followingcontrol commands over a fieldbus network.Control BitsBit 0/1 0 = Open command, activate Output 2 forpulse width1 = Close command, activate Output 1 forpulse widthBit 2 This bit can be used to switch between Local andRemote from the network when the Allow RemoteControl Switch parameter is enabled.Bit 3 0 = No action1= Reset fault (will clear fault provided conditionhas cleared)Bit 5 0 = No action1 = The C445 will issue a “Test Trip” fault causingthe Output 2 control relay to produce an output pulseto open the MCCB feeder.Control Status WordThe control status word of the MCCB feeder control profilecan be accessed over the fieldbus network.Status BitsBit 0 0 = Open (open command is active1= Close (close command is active)Bit 1 0 = circuit breaker not in tripped position(CB alarm = false)1= circuit breaker in tripped position (CB alarm = true)Bit 2 0 = local control source active1= remote control source is activeBit 3 0 = no fault present1= C445 fault presentBit 4 0 = no warning present1= C445 warning presentBit 5 0 = no inhibit present1= C445 control inhibit presentBit 6 0 = C445 not ready (fault and/or inhibit present)1= C445 ready for control (No fault or inhibit present)Bit 7 0 = MCCB feeder is in open/tripped position(CB on = false)1= MCCB feeder is in closed position (CB on = true)Configuration Parameter Modbus Register Description Read/WriteActive Operation Mode 1 700 This parameter selects the Operation Mode R/WControl Fault Delay 701 Delay time before a control fault is issued. Setting of “0” disables protection.
