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

Example

A high level backup switch is connected to Digital Input Two in the same application as

Transducer One at level value 4.3m.

Settings

When the level rises to 4.3m and the switch is activated, the reading is forced to 4.3m

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.
