7.4.1
Backup level override parameters
Discrete Input Number (2.9.1.2.)
Sets the discrete input as the source of a level reading override
Level Override Value (2.9.1.3.)
Substitutes value for current reading when Discrete Input Number (2.9.1.2.) (Page 208) is
activated. Value is added in current units and is valid only for the following:
●
Level
●
Space
●
Distance
●
Difference
●
Average modes of operation
●
Head level in OCM mode
Example
A high level backup switch is connected to Digital Input 2 in the same application as
Transducer 1 at level value 4.3 m.

–
When the level rises to 4.3 m and the switch is activated, the reading is forced to 4.3 m
where it stays until the switch is de-activated.
Override Time Delay (2.9.1.4.)
Sets the time (in seconds) used to calm the override condition input

Discrete inputs
Discrete input logic affects the reaction of the discrete input. Normal state is the standard
operation, with the device sensing the material level and controlling the pumps.
