– User Guide
On receipt of the prepayment voucher, the meter processes it and, when complete, submits the result
back to the customer interface unit. Depending on the result, the customer interface unit displays one
of the sequences described in 7.4. Again, depending on what sequence is invoked, the keypad could
remain locked for a variable period of time i.e. it will not respond in any way to further key presses.
An incomplete voucher entry will be timed-out after 30 seconds; where after the customer interface
unit reverts to normal operation.

7.4
Prepayment Voucher Processing
Depending on the type of voucher entered into the meter, it will result in one of the display sequences
described below. Note that with the exception of an „incomplete voucher‟ – 7.4.1, the customer
interface unit only displays these sequences on receipt of a valid response from the meter. Because
there can be some delay in the PLC communication between the customer interface unit and the
meter, the sequences are always preceded by the scrolling „busy‟ display – refer to section 12 for
more details on PLC communication:
7.4.1
