Control Settings
The following parameters are used to configure the Solenoid
Valve Operation Mode and the C445 sources of control.
Table 18. Solenoid Configuration Parameters
Note
1
Soft reset (power cycle) required for changes to these parameters to take effect.
Fieldbus Control Word
The solenoid valve control profile will accept the following
control commands over a fieldbus network.
Control Bits
Bit 0
0 = De-energize command, de-activate Output 1
1 = Energize command, activate Output 1
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 t
he Output 1 control relay to open.
Control Status Word
The control status word of the reverser motor starter profile
can be accessed over the fieldbus network.
Status Bits
Bit 0
0 = De-energize (No active energize command)
1= Energize (Energize command is active)
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
Configuration Parameter
Modbus Register Description
Read/Write
Active Operation Mode
1
700
This parameter selects the Operation Mode
R/W
Solenoid Open Time Delay
708
Time for the solenoid to reach it’s open position, control fault is masked during this
time. A setting of “0” disables control fault protection for opening.
Solenoid Close Time Delay
709
Time for the solenoid to reach it’s closed position, control fault masked during this
time. A setting of “0” disables control fault protection for closing.
Solenoid Non-energized State
710
Non energized state of the solenoid valve
0 – normally closed (default
1 – normally open
R/W
Trip Enable Bit Field
1000-1001
Trip (Fault) protection enable bits
Set bits to enable desired protections
R/W
Warn Enable Bit Field
1002-1003
Warning protection enable bits
Set bits to enable desired protection warnings
R/W

R/W
C445 Feedback Signal Source Selector
713
Input source of the feedback signals
0 – No feedback source
1 – User interface inputs
2 – Base control inputs
3 – Fieldbus parameter
