OPERATION
When the Quick Start procedure is complete...
1.
"----" is displayed briefly...
The AIRANGER DPL PLUS rapidly takes measurements,
verifies repeatability, and calculates Readings.
For one vessel, the Reading is displayed continuously.
For two vessels, Readings are scroll displayed.
Difference or Average Readings (if selected) are also scroll
displayed, as Point Number 3.
The Bar Graph indicates material level (0 to 100%),
regardless of the Operation selected.
If "▲" is displayed the vessel level has exceeded 80% and
not yet fallen below 75% (Hi Alarm).
If "▼" is displayed the vessel level has fallen below 20% and
not yet exceeded 25% (Lo Alarm).
When in alarm, the corresponding relay is de-energized.
2.
Readings are displayed in % (based upon Operation).

4.
View the Failsafe Time Left in % (before "LOE" is displayed).
If the value reaches 0, the "old" Reading, Bar Graph, relays,
and mA outputs are "held" and "LOE" flashes.
When a valid measurement is made, the value resets to 100.
The AIRANGER DPL PLUS advances to the "new" level;
operating displays and outputs accordingly.

PERFORMANCE EVALUATION
Monitor system performance, under all operating conditions.
If alternate display, relay, or mA output operation is required,
or "LOE" is displayed, see instruction manual PL-421.
Connect (or enable) alarm/control equipment only after
satisfactory performance is verified.
