Backup level override
Backup level override provides the option of overriding the ultrasonic input with another
contacting point level device (for example, the Pointek CLS200). The ultrasonic reading is
fixed at the programmed switch level until the discrete input is released; the override is
then removed, and the HydroRanger 200 HMI returns to normal measurement.
Backup level override parameters
2.9.1.2. Discrete Input Number
Sets the discrete input as the source of a level reading override.
2.9.1.3. Level Override Value
Substitutes value for current reading when
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.

2.9.1.3. Level Override Value
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.
2.9.1.4. Override Time Delay
Sets the time (in seconds) used to calm the override condition input.
