Buzzer Operation

4.3.1 Low Credit Warning
E470 Tokenless Smart Prepayment Meter
Issue: 1.8
The meter will allow codes to be re-entered for up to 10 minutes and will
allow the entry of 5 sets of invalid codes. If a valid code is not entered after
a total of 10 minutes, or 5 invalid attempts are made during this period, the
display will revert back to the Default Operating display. If 5 invalid entries
are made the facility will be locked out until the next hour.
The meter will allow a maximum of 5 sets of Payment code entries in a
24hr period.
Example
1pm: Enter invalid code 5 times
Must wait until 2pm before allowed to re-enter code
2pm Enter invalid code 5 times
Must wait until 3pm before allowed to re-enter code
3pm Enter invalid code 5 times
Must wait until 4pm before allowed to re-enter code
4pm: Enter invalid code 5 times
Must wait until 5pm before allowed to re-enter code
5pm Enter invalid code 5 times
Facility locked out until 00:01 next day
If no button presses are detected after 60 seconds the display will revert
back to the normal operating display.
A further use of the code entry mode is to instigate the binding process for
external devices or an installation mode.
When instigating these processes a 6 digit pin is entered into the first 6
digits of the payment code. If the entered pin corresponds to one of the
configured pins then the meter will enter the appropriate mode. See
installation section.
The meter uses an audible buzzer to indicate to the consumer the following
events:
 Low Credit warning
Valid Button press

Incorrect Entry of Purchase Code.

The Low credit warning will operate when the Present Balance register
value falls below the Emergency Credit Availability point and Emergency
credit is available.
If the Present Balance register falls below the Emergency Credit Availability
point during a Non-Disconnection period, the Low credit warning will be
suspended until the Non Disconnection period has ended.
