You may choose from among the following leak test frequency options:

DAILY (QPLD will be selected if the Leak Test Frequency is set to daily, and the Leak Start Time is disabled.
This feature is only available if HRM has been enabled [see “TLS-350 Consoles” on page 4-1]).
•
AUTOMATIC (requires that the tank be assigned to a Line Leak Detector [see “Tank Selection” on page 10-7 for
PLLD, “Tank Selection” on page 11-6 for WPLLD, or “Pipe Label and Tank Identification” on page 12-1 for
VLLD], or a Pump Sense input - see Chapter 15)
•
CSLD (runs leak tests automatically during idle tank times and stores data for leak test reports)
NOTE: The CSLD option appears only when the tank is equipped with a 0.1 gph (0.38 lph) Mag probe, and the
system has the
CSLD
software module key installed.
