7.4 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 device returns to normal measurement.
