This screen lets you enter tank capacity and tank alar
m
set points. These tank li
m
its provide
the ability for the syste
m
to warn of conditions that
m
ay arise that need i
mm
ediate address-
ing. When progra
mm
ing tank li
m
its, the custo
m
er should discuss their needs with a Veeder-
Root representative to deter
m
ine these levels.
Max. Volume (Label Vol.)
Set this value at 100% of the tank’s capacity (see alar
m
references diagra
m
below). The
m
axi
m
u
m
volu
m
e or label volu
m
e alar
m
s occur when the level of fluid in the tank exceeds
the value entered in this field.
High Product (% of max. vol.)
High Product alar
m
s occur when the volu
m
e 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 syste
m
to recognize the increase as a deliv-
ery and possibly fail to activate the Delivery Overfill Li
m
it Alar
m
.
In International Sites this field is useful to warn of an i
m
pending over-fill (it can trigger the
sa
m
e alar
m
indications as Overfill Li
m
it):
• Set this li
m
it to 98% if the Maxi
m
u
m
(Label) Volu
m
e value is greater than 25,000 liters.
• Set this li
m
it to 96% if the Maxi
m
u
m
(Label) Volu
m
e value is less than 25,000 liters.
Delivery Overfill (% of Max. Volume)
Delivery overfill alar
m
s alert you to potential overfill condi-
tions during a delivery. When the volu
m
e reaches this value,
the console can activate an overfill alar
m
and can trigger a
printout showing the tank nu
m
ber, date, ti
m
e, 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
m
axi
m
u
m
(label) Volu
m
e.
Delivery Limit (% of Full Volume)
Delivery li
m
it alar
m
s occur when the volu
m
e of product in
the tank drops to a level at which you should request a deliv-
ery. This is referred to as the
m
ini
m
u
m
operating capacity.
Set this value at a volu
m
e higher than that of the Low Prod-
uct Volu
m
e 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
m
ade. Nor-
m
ally, this is set around 5-10% of the tank's capacity. A Low
Product alar
m
s alert you when the volu
m
e in the tank drops
to the low product level.
International Sites
Assu
m
ing no water is present in the tank, this li
m
it should be
set no lower than
m
ini
m
u
m
volu
m
es that can be
m
easured
by each probe type:
• The tank volu
m
e at 250
mm
for Mag probe type 8473
• The tank volu
m
e at 125
mm
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 require
m
ent
to know when and how
m
uch water you have in the tank.
Typical water warning setting is 2 inches and is lower than
the high water alar
m
.
NOTE: This
m
essage 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 alar
m
value,
the console triggers an alar
m
. Set this value at a level lower
than the pickup for the sub
m
ersible pu
m
p or suction line.
NOTE:
This
m
essage does not appear for tanks in which high
alcohol probes are installed.
