Control Settings
The following parameters are used to configure the MCCB
Feeder Operation Mode and the C445 sources of control.
Table 19. MCCB Configuration Parameters
Note
1
Soft reset (power cycle) required for changes to these parameters to take effect.
Fieldbus Control Word
The MCCB feeder control profile will accept the following
control commands over a fieldbus network.
Control Bits
Bit 0/1 0 = Open command, activate Output 2 for
pulse width
1 = Close command, activate Output 1 for
pulse width
Bit 2
This bit can be used to switch between Local and
Remote from the network when the Allow Remote
Control Switch parameter is enabled.
Bit 3
0 = No action
1= Reset fault (will clear fault provided condition
has cleared)
Bit 5
0 = No action
1 = The C445 will issue a “Test Trip” fault causing
the Output 2 control relay to produce an output pulse
to open the MCCB feeder.
Control Status Word
The control status word of the MCCB feeder control profile
can be accessed over the fieldbus network.
Status Bits
Bit 0
0 = Open (open command is active
1= 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 active
1= remote control source is active
Bit 3
0 = no fault present
1= C445 fault present
Bit 4
0 = no warning present
1= C445 warning present
Bit 5
0 = no inhibit present
1= C445 control inhibit present
Bit 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)
