1.2 Distance-read Leak Detection When the Liqui-tect LP3000 measures a current in excess of the defined leak threshold, the microprocessor computes the distance to the leak, annunciates the leak, and logs the alarm in the event log. The leak is communicated via the front-panel display and other configured notification methods.
The LED display cycles through the following 4 lines, then returns to the default display (un-less the Re- Alarm Interval is updated, an existing alarm may display. Refer to Leak Settings on page 23.) LeakageC nnnn uA Length nnn ft (or nnn m) Vertiv | Liqui-tect LP3000 Installer/User Guide |...
