Prepay is similar to preset money, but it allows you to choose a specific fuel grade. When you select a fueling point, you will see all the available grades. Unlike preset money, this option does not automatically authorize the pump; you must authorize it manually afterward. Additionally, the fueling point does not need to be in the "Idle" state for the authorization to be successful.
If you choose "Any grade," any grade can be used for your next fuelling. If you select a specific grade, only that grade can be used for the next fuelling.
After confirming this input nothing happens, the fuelling point keeps the state.
Fueling point 1 is now prepaid for grade option 2. If a non-matching grade nozzle is lifted, the state is set to "Calling," and dispensing does not start.
The incorrect nozzle is replaced, the correct nozzle is lifted, and dispensing begins until the preset amount is exceeded or the nozzle is manually replaced beforehand.
The transaction is created when the nozzle is replaced. It is also automatically locked with the POS ID of the connection that made the prepayment. Once this transaction is cleared, the fueling point is restored to its normal state.
