Leak Alarm Limit
If necessary, press STEP until you see the message:
During a leak test, Leak Alarm Limit warns when the cumulative temperature compensated product loss from a
tank reaches the limit value. The system automatically interprets the limit you enter as a negative. It is not
necessary to enter the minus (-) sign.
The Leak Alarm Limit is intended to identify and warn of large losses of product during a leak test. Small changes
in fuel conditions can cause temporary variations in fuel level reading that balance out over the duration of a test in
a tight tank.
To prevent false reports and alarms from being triggered, do not set the limit value to identify losses of 0.2 gph
(0.76 lph) or less during the test period. The Leak Limit should be set to identify losses of 1 gph (4 lph) or greater.
Consider the leak rate you wish to identify and the length of the test when determining a limit value. A limit value of
8 gallons (32 litres) will warn of a 1 gph (4 lph) leak in 8 hours or a 2 gph (8 lph) leak in 4 hours.
To enter the Leak Alarm Limit, press CHANGE. Enter the limit in gallons (from 1 to 99) or litres (from 4 to 399),
depending on the units set up in System Units. Press ENTER to confirm your entry. The system displays:
Sudden Loss Limit
If necessary, press STEP until you see the message:
Sudden Loss Limit immediately warns of a sudden loss of fuel during a leak test. It is not based on temperature-
compensated volume and is intended to identify losses larger than the Leak Alarm Limit. Typically, you should set
this limit at 25 gallons or 100 litres, or higher.
To enter the Sudden Loss Limit for the selected tank, press CHANGE. Enter the limit in gallons or litres,
depending on the units specified in System Setup. Press ENTER to confirm your entry. The system displays:
Tank Tilt
The following Tank Tilt procedure is for U.S. installations. For international installations, see Appendix A.
Consoles w/ BIR
only--Entering a Tank Tilt value is not recommended if the system is performing automatic
Business Inventory Reconciliation and AccuChart.
If the probe is installed in the center of the tank, the value is 000.00 U.S.; 0000.0 Metric.
