9.2 Setup (2.)
Enable (2.9.1.1)
Enables/disables the Backup Level Override function.
Options
Level Override Value (2.9.1.2)
This value is substituted for the current reading when the selected discrete input is enabled
and ON.
Values
Value is defined in current Units (2.1.1.) (Page 172), and is valid only for level (and head
when Sensor Mode (2.1.2.) (Page 173) set to Flow). (Volume is calculated based on the
Backup level.)
Discrete Input Number (2.9.1.3)
Sets the discrete input to act as the source for a level reading override when enabled.
Options
9.2.9.2
Discrete Input Logic (2.9.2)
Use the following parameters to configure the discrete input itself.
Normal state is standard operation, with the SITRANS LUT400 sensing the material level and
controlling the pumps, and no faults or alarms present. The discrete input contacts are either
NORMALLY OPEN or NORMALLY CLOSED when the system state is normal.
Discrete Input Logic
Normally Open
Normally Closed
For example:
When discrete input logic is set to Normally Open and discrete input has no voltage applied
on the terminal block, the discrete input will be inactive (OFF).
Discrete Input 1 Logic (2.9.2.1)
Use to change the behaviour of the Discrete Input 1.
