High Filter - Maximum Height for the No-Delay Condition
If water level is 10 inches or more for three minutes, then the Console posts a High Water Alarm and High
Water Warning, even when a Delivery is in progress.
Leak Alarm Limit
During a Leak Test the Leak Alarm Limit warns when the cumulative TC Product loss from a Tank
reaches the Leak Alarm Limit. It identifies and warns of large losses of Product during a Leak Test.
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 Alarm Limit should be set to identify losses of 1
gph (4 lph) or greater.
Consider both the leak rate you wish to identify and the length of the test when determining a value for
Leak Alarm Limit. A value of 8 gallons (32 liters) will warn of:
• A 1 gph (4 lph) leak in 8 hours.
• A 2 gph (8 lph) leak in 4 hours.
Note: the system automatically interprets the limit you enter as a negative. It is not necessary to enter the
minus (-) sign.
Sudden Loss Limit
Sudden Loss Limit (theft alarm limit loss) immediately warns of a sudden loss of fuel during a leak test. It
is not based on TC Volume; it is intended to identify losses larger than the Leak Alarm Limit (See above).
Typically, you should set this limit at 25 gallons (100 litres), or higher.
Density Low Limit
Density Low Alarms occur when the Fuel Density value falls below the value you enter in this field.
Density High Limit
Density High Alarms occur when the Fuel Density value rises above the value you enter in this field.
