Setup>Tank>Limits
This screen lets you enter tank capacity and tank alarm set points. These tank limits provide
the ability for the system to warn of conditions that may arise that need immediate address-
ing. When programming tank limits, the customer should discuss their needs with a Veeder-
Root representative to determine these levels.
Max. Volume (Label Vol.)
Set this value at 100% of the tank’s capacity (see alarm references diagram below). The
maximum volume or label volume alarms occur when the level of fluid in the tank exceeds
the value entered in this field.
High Product (% of max. vol.)
High Product alarms occur when the volume of fluid in the tank exceeds the value you enter
in this field, typically set to 95%.
In U.S. installations, this is especially useful in applications such as in used-oil holding tanks,
where the rate of fill can be too gradual for the system to recognize the increase as a deliv-
ery and possibly fail to activate the Delivery Overfill Limit Alarm.
In International Sites this field is useful to warn of an impending over-fill (it can trigger the
same alarm indications as Overfill Limit):
• Set this limit to 98% if the Maximum (Label) Volume value is greater than 25,000 liters.
• Set this limit to 96% if the Maximum (Label) Volume value is less than 25,000 liters.
Delivery Overfill (% of Max. Volume)
Delivery overfill alarms alert you to potential overfill condi-
tions during a delivery. When the volume reaches this value,
the console can activate an overfill alarm and can trigger a
printout showing the tank number, date, time, and product.
Set this percentage no greater than 90% of the tank capacity.
For International Sites, set this percentage to no greater
than 99% of maximum (label) Volume.
Delivery Limit (% of Full Volume)
Delivery limit alarms occur when the volume of product in
the tank drops to a level at which you should request a deliv-
ery. This is referred to as the minimum operating capacity.
Set this value at a volume higher than that of the Low Prod-
uct Volume field.
Low Product
Low product is typically used to indicate that the inventory is
at a critical point and the operator/owner should consider
taking the tank out of service until a delivery is made. Nor-
mally, this is set around 5-10% of the tank's capacity. A Low
Product alarms alert you when the volume in the tank drops
to the low product level.
International Sites
Assuming no water is present in the tank, this limit should be
set no lower than minimum volumes that can be measured
by each probe type:
•The tank volume at 250mm for Mag probe type 8473
•The tank volume at 125mm for Mag probe type 8493
High Water Warning
When you have a Mag probe with water detection, you can
set this threshold to provide a warning condition when water
enters the tank. In the United States, there is a requirement
to know when and how much water you have in the tank.
Typical water warning setting is 2 inches and is lower than
the high water alarm.
NOTE: This message does not appear for tanks in which high
alcohol probes are installed.
High Water Alarm
When water in the tank rises to the high water alarm value,
the console triggers an alarm. Set this value at a level lower
than the pickup for the submersible pump or suction line.
NOTE: This message does not appear for tanks in which high
alcohol probes are installed.
