FUEL ALLOCATION EXAMPLES
The allocation option works in conjunction with the limits you set up for each user with the LL
command. Be sure that you have assigned reasonable fuel limitations; unrealistic limits can cause
system tie-ups when used with the allocation option. Consider these two examples: the first
describes standard operation of the allocation option; the second, what happens when two users
with the same allocation number attempt to fuel at the same time.
Example 1:
Assume user A has a limit of 40 liters per transaction and an allocation limit of 400 liters a month.
When user A attempts to fuel his vehicle, the Series 1000 sets aside 40 of these 400 liters. If user
A pumps 40 liters, 40 are decremented from the allocation totalizer. If only 35 liters are pumped,
35 are decremented and the unused 5 are returned to the allocation totalizer.
If user A has less than his limitation amount remaining in his allocation totalizer, the lesser amount
is authorized.
Example 2:
When two users that have the same allocation number try to get gas at the same time, the second
card to be authorized can only get the amount in the allocation totalizer minus what the first card is
authorized for. This is why it is important to keep the limitation amounts reasonable. In an
extreme example, assume that individuals A and B, (who share the same allocation number) have
limits of 400 liters each. The allocation totalizer for these individuals is currently 400. When user
A runs his card, his encoded 400 liter limit is decremented from the totalizer leaving a balance of
zero. If user B attempts to run a transaction at the same time, he cannot get his fuel until user A is
finished. If user A takes all 400 liters, user B cannot fuel until a new allocation amount is set. If
users A and B had been assigned reasonable limits (i.e., maybe 100 liters), they could have fueled
simultaneously and had allocation left over.
