Product Limit (Enter LIMIT) Preparation for Programming
Product Limit (Enter LIMIT)
The Product Limit code is used to restrict the maximum quantity of fuel dispensed per
transaction. It is provided as a safeguard to prevent accidental spillage. FleetKey can handle
up to 10 limit codes (0-9), and CFN systems can handle up to 100 (default is 20). The limit
codes do not have to be numbered sequentially. In both systems, not having the limit code on
the VM is the same as if it was on with code 0.
The limit code programmed in the VM is not an actual quantity amount. When your
Authorized Service Representative (ASR) configures your FMS, a table is set up to your
specifications. The table contains limit codes and quantity values assigned to those limit
codes. Limit codes are linked with a type of vehicle and are assigned a quantity just slightly
greater than the vehicle's fuel tank capacity.
Complete Table 4-1, Product Limit Codes, prior to programming the VM. Make sure the
completed table is available at start-up, so it can be loaded into the system at that time.
Photocopy this sheet if you need more space.

Limit Code Quantity
Product Authorization (Enter AUTH)
This code authorizes the fuel types the vehicle is allowed to access. An authorization code
allows one or more fuel types, also represented as codes. FleetKey can handle up to 9 (1-9)
authorization codes and each code allows up to 5 fuel types. CFN systems can handle up to
100 authorization codes and each code allows up to 100 fuel types (default is 40). In FleetKey,
authorization code 0 always allows all fuel types. In CFN systems, if no fuel types are loaded
for authorization code 0, it will allow all fuel types, otherwise, code 0 will allow the fuel types
loaded. In both systems, not having the authorization code on the VM is the same as if it was
on with code 0.
First, assign a 2-digit fuel code to each of your fuel types, using Table 4-2. Then, assign the
fuel codes to the authorization codes as you require, using Table 4-3. Make sure this
information is available to load into the FMS at start-up. Photocopy these sheets if you need
more space.
