UINT8 RW NV
Default: 0
Enum
Config CRC
Run Lock
Admin Lock
USB Lock
Backup Mem
Selects the source of the digital inputs used for the feedback signals for
certain operation modes. The operation modes that require digital input
feedback are: Solenoid, MCCB Actuation and Contactor Feeder. This
parameter allows the user to select where the inputs are wired to the
C445. To the Base Control Module, the User Interface or to a controller
where they are sent to the C445 via a communication network. For all
three locations these input feedback signals may be wired, the actual
input or bit is pre-defined for each as follows. Solenoid Operation
Mode: 1. Base Control Module: Input 2 (open), Input 3 (closed)
3. Input Register 602 from a controller: Bit 1 (open) and Bit 2 (closed)
Contactor Feeder Operation Mode: 1. Base Control Module: Input 2
(AUX On) 3. Input Register 602 from a controller: Bit 1 (AUX On) MCCB
Feeder Operation Mode: 1. Base Control Module: Input 2 (CB On), Input 3
(CB Alarm) 3. Input Register 602 from a controller: Bit 1 (CB On), Bit 2
(CB Alarm)
