Backup Level Override
Backup Level Override
Backup level override provides the option of overriding the ultrasonic input with another
contacting point level device, for example, the Pointek CLS 200. The ultrasonic reading is
fixed at the programmed switch level until the discrete input is released and the
ultrasonic device makes its decisions based on the override value.
Backup Level Override Parameters
P064: Reading Override Enable
Sets the discrete input as the source of a level reading override.
P065: Reading Override Value
Substitutes value for current reading when the discrete input (P064) is enabled. 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 Two in the same application as
Transducer One at level value 4.3 m.
Settings
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.
P066: Override Time Delay
Sets the time (in seconds) used to calm the override condition input.
Parameter Index Value
P064 1 2
P064 2 0
P065 1 4.3
P065 2 –
